[Facing My Fears: The Data and Emotional Rollercoaster of My Re-hospitalization & Precision Needle Biopsy]

My hospitalization was triggered by persistently high IgG4 levels—suggesting possible Autoimmune Pancreatitis (AIP)—along with a visibly swollen pancreas on my contrast CT and MRI scans. To get a definitive answer, I was put under close observation.
IgG4 Reference Levels: 146 (At admission) → 135 (1 month later)
The thought of an Endoscopic Ultrasound-Guided Fine-Needle Aspiration (EUS-FNA)—where a fine needle is passed through the stomach wall to harvest tissue—was absolutely terrifying. The mere mental image stressed me out. A knowledgeable friend even warned me, "If it's a tricky procedure, you should swap hospitals to find a high-volume specialist." I was torn, but ultimately stuck with my original doctor. Funnily enough, when I researched it a few days beforehand, I realized this is actually a very standard procedure and not nearly as daunting as I'd feared (lol!).
On the day of the procedure, the sedative knocked me right out, and the next thing I knew, I was back in my hospital room. It felt just like getting a routine endoscopy. Aside from a slightly bloated tummy, I felt completely fine. I breathed a huge sigh of relief when my doctor confirmed, "Everything went perfectly." If the results came back positive, I would have faced the ultimate challenge for a Type 1 Diabetic: steroid therapy and the explosive blood sugar spikes that come with it. Waiting for the results was an absolute nerve-wracking ordeal.

[The Verdict: My Test Results]

Two weeks later, the biopsy results came back. (According to medical guidelines, they look at things like the rate of abnormal cell infiltration). The verdict? "The pancreas does not present like AIP. Pathology is negative for AIP. => No issues detected." In that single moment, the dark cloud of cancer and autoimmune pancreatitis fears completely vanished.
Fast forward three months: a follow-up MRI scan officially confirmed that the swelling and inflammation in my pancreas had completely subsided and resolved.
While the root cause of the "fulminant type 1 diabetes" that suddenly struck me remains a mystery, we cleared up its connection to my pancreatic swelling. Now, I can focus solely on managing my blood sugar with insulin, without needing any unnecessary extra treatments.

【Summary】

Since being discharged, my daily routine has revolved around insulin injections before every meal and finger-prick blood sugar checks.

But after getting through that follow-up hospitalization and biopsy, I received the ultimate peace of mind: my biggest fears (pancreatic cancer and autoimmune pancreatitis) were completely ruled out. Best of all, I don't need steroid therapy anymore. Now, I can pour 100% of my energy into my daily insulin routine and mastering my blood sugar control.

Survived the dreaded needle biopsy and got a clean bill of health, putting my biggest worries to rest.
Successfully avoided steroid treatments that would have sent my blood sugar levels through the roof.
The final MRI confirmed that the pancreatic inflammation from when my fulminant diabetes first struck has fully cleared up.

I decided to track my blood sugar levels after treating myself to Chateraise's "Freshly Squeezed Milk Bar - Coffee Flavor." As expected, my numbers shot up post-indulgence. Thanks to the high fat content of the ice cream, my glucose spiked quickly and then lingered at a high level for quite a while.

Ingredients & Nutrition: This treat is officially classified as premium "ice cream" with a relatively high milk fat content of 9.0%. Since dietary fat slows down digestion and delays carb absorption, my blood sugar didn't just spike immediately—it remained elevated well into the night.

[Quick Summary]

Right before 10:00 PM, I was heading into low blood sugar territory. My glucose had dipped to 69 mg/dL, but it spiked dramatically after eating the ice cream bar.
At its peak, my glucose reached 199 mg/dL, creating a massive spike with a total fluctuation of +105 mg/dL.
Even past 11:30 PM, my levels refused to come down, staying elevated for quite some time.

[Blood Sugar Data After Eating the Ice Cream]

Around 10:00 PM: Started on the lower side, right around 69 mg/dL just before eating.
10:00 PM – 11:30 PM: Levels began climbing immediately after eating, steadily rising over the next hour and a half.
Around 11:30 PM: Reached my peak for the night at 199 mg/dL, where the rise finally plateaued.
After Midnight: Although it dropped slightly past the peak, my glucose hovered stubbornly around 140 mg/dL even by 1:00 AM.

The Blood Sugar Diaries: Surviving My First Hospital Stay and a Type 1 Diabetes Diagnosis

📌 Related Support Tools: Discover useful goods & low-carb management options on Amazon (Affiliate Link)

Hospital Diaries: Life in the General Ward

It was my first time ever being hospitalized. I was assigned to a four-person room, specifically designated for "independent" patients who could take care of their own basic needs.

My roommates were mostly men in their 50s to 70s. If it had been a long-term stay, I would have broken the ice and tried to make friends, but I was scheduled to be discharged in less than a week. Plus, I didn't know their medical situations. Everyone kept their privacy curtains tightly shut, so the only sounds were occasional snippets of conversation with the nurses.

Even so, those brief overheard conversations painted a picture of what each person was going through.

Roommate #1: A middle-aged man fighting cancer
He was constantly complaining about severe constipation, lamenting that even laxatives didn't work and had caused him hemorrhoids. He was a bit lively and vocal, often grumbling about how much the blood draw needles hurt.
Roommate #2: An elderly diabetic man transferred from a nursing home
He didn't seem to have any family visiting. The real challenge was—to put it bluntly—his silent but incredibly deadly flatulence. It was so overwhelming that I couldn't bear the smell, and I actually had to ask my family to bring a portable handheld fan from home just to survive.
Roommate #3: A mysterious patient who left after three days
He seemed anxious to get discharged quickly because his child had upcoming school entrance exams. However, his prescribed medication didn't seem to agree with him; he kept complaining of feeling unwell and having no appetite, which ended up delaying his release.
Roommate #4: The elderly man who took his place
He was admitted for some internal organ issues. He frequently muttered to himself, saying things like, "I'm finished..." or "I just want to die." It was heartbreaking to listen to.

All these different lives playing out just on the other side of a curtain. It made me pause and wonder: "How did I look to the rest of them?"

Diabetes Education

During my stay, I had daily "diabetes education" sessions, rotating between my doctor, nurses, dietitians, and physical therapists.

How diabetes actually works in the body
The "SHIMEJI" and "ENOKI" acronyms (classic Japanese mnemonics for diabetic complications) and how to handle sick days
The difference between "long-acting" (basal) and "rapid-acting" (bolus) insulin
How carbs, proteins, and fats impact your body

They thoroughly drilled me on these essentials—vital knowledge I'll need for managing my condition moving forward.

Heading Home

Thanks to the comprehensive diabetes training, the anxiety that had consumed me at first began to fade, and I was finally able to welcome discharge day with a calm mind.

My daughter came to pick me up. We walked home together, wheeling our bicycles and chatting about everything and nothing. It was in that simple, ordinary moment that I realized I was finally getting my life back.

When my hospital stay finally ended and I was discharged, I felt an overwhelming sense of relief. Taking in that first breath of fresh air outside, I thought, "I'm finally back in the real world!" At first, when they suspected all sorts of terrifying illnesses, my mind went completely blank. But after undergoing extensive testing and pinpointing the exact cause, I felt empowered to make a positive, proactive start on my new lifestyle. Keeping everything I learned in mind, and holding onto the joy of that walk home with my daughter, I’m ready to take it one step at a time and work in harmony with my body.

【Summary】

Despite a tense scare with elevated tumor markers and immune system indicators, follow-up scans showed zero abnormalities, bringing immense relief.
As the severe internal inflammation triggered by the rapid spike in my blood sugar subsided, all of my lab values naturally stabilized.

📊 Discharge Test Results & Key Takeaways

Though I had a major scare when my tumor markers, CEA (6.5) and CA19-9 (45), flagged potential pancreatic cancer, my contrast-enhanced CT scans showed absolutely no tumors or abnormal blood flow.
My IgG4 levels (140+) raised suspicions of autoimmune pancreatitis. However, since the imaging showed none of the swelling typical of the pancreas, both scary possibilities were ruled out, leaving me with a clean bill of health and a simple "follow-up/no issues" diagnosis.
It turns out this alarming spike in numbers was just a temporary disruption triggered by severe hyperglycemia and intense internal inflammation. As my treatment progressed, the numbers naturally settled back to normal.

Weekly Blood Glucose Management Summary

Looking back at this week's blood glucose management, it was a week with a significant shift in blood glucose patterns between the first and second half of the week. Overall, the average blood glucose level was 181 mg/dL, and the Time in Range (TIR) was 48.4%. Although the time spent within the target range was slightly less than half, I could feel my control improving day by day, which kept me feeling positive.

A particularly positive aspect was that the average blood glucose level gradually decreased toward the latter half of the week, settling at 127 mg/dL on Friday. On the other hand, I noticed some periods where blood glucose trended high from nighttime to early morning, as well as times during the day when it dropped close to hypoglycemia. Next week, I want to focus on stabilizing nighttime levels and preventing sharp daytime drops, aiming for more comfortable and steady control.

Weekly Trend Analysis

Let's take a closer look at this week's weekly trend. The weekly average blood glucose level was 181 mg/dL, and the Time in Range (TIR: the percentage of time blood glucose remains within the target range of 70–180 mg/dL) was 48.4%. Additionally, the coefficient of variation (CV), which measures blood glucose variability, was 32.0%. Since this is below the generally recommended threshold of 36%, the overall blood glucose fluctuations can be considered relatively stable.

The highest level recorded was 306 mg/dL on Tuesday at 14:45, and the lowest was 66 mg/dL on Thursday at 14:30. In the second half of the week, there was an increase in the time blood glucose stayed below the green baseline (180 mg/dL), which was a positive change. Note that GMI (Glucose Management Indicator/estimated HbA1c) and comparison data with the previous week could not be confirmed from the images in this report. I hope to carry the stable momentum from the latter half of this week into next week.

Daily Summary Analysis

Looking at the daily summary for each day of the week, there is a clear trend change between the first and second half of the week. Starting with an average of 190 mg/dL on Sunday, followed by 222 mg/dL on Monday, and a weekly high average of 235 mg/dL on Tuesday, levels remained generally high during the first half. It is possible that the portion sizes and content of meals, or the typical busyness at the start of the week, had some influence during this period.

However, things gradually improved from Wednesday onward. The average fell to 162 mg/dL on Thursday, and on Friday, I achieved the week's best average of 127 mg/dL. On Friday, my blood glucose levels remained stable throughout the day, and I felt very light and energetic. From Thursday to Saturday, the lowest blood glucose levels dropped to around 66–71 mg/dL from afternoon to late afternoon, suggesting a need to adjust daytime activity levels or the timing of lunch and snacks.

AGP Analysis

Let's analyze the Ambulatory Glucose Profile (AGP), which overlays 24-hour glucose variability patterns. Looking at this, from nighttime to early morning (around 00:00 to 06:00), the median (dark blue line) trends above 200 mg/dL, indicating a hyperglycemic tendency. Since glucose levels remain relatively high during sleep, there may be room for improvement in the timing and menu of dinner.

Looking at daytime trends, there is a temporary rise after breakfast around 08:00, followed by a sharp drop toward 14:30 in the afternoon. During this time, the 5th percentile (the lower limit of the light-shaded area showing the lowest variability range) falls below 70 mg/dL, indicating an increased risk of temporary hypoglycemia. After evening, levels rise gradually again, leading to high nighttime glucose after 21:00. Preventing the sharp drop in the early afternoon and the high levels overnight will be key points moving forward.

Highlights of the Week

Being able to achieve a highly stable day in the latter half of the week (especially Friday) with an average blood glucose level of 127 mg/dL.
The coefficient of variation (CV), which indicates blood glucose variability, was well within the target at 32.0%, below the 36% threshold.
Maintaining a positive trend of decreasing daily average blood glucose levels day by day starting from Wednesday.

Areas for Improvement for Next Week

Paying attention to the carb content and timing of dinner to prevent blood glucose levels from staying high overnight and into the early morning.
Reviewing lunch options or incorporating appropriate snacks as needed to prevent the sharp drop in blood glucose (hypoglycemia risk) observed around 14:30.
Being mindful of the tendency to have high blood glucose during the first half of the week (Monday and Tuesday) and managing dietary habits more carefully at the start of the week.

Summary

Although levels were slightly high in the first half of the week, it was a wonderful week as I managed to bring control back on track toward the second half. Being able to visually understand my body's rhythms and when blood glucose is most likely to fluctuate makes planning solutions much more encouraging. Without striving for perfection, let's continue to build comfortable, healthy days next week while enjoying small daily adjustments!

Navigating Type 1 Diabetes: My Journey to Mastering Blood Sugar Control

📌 Related Support Tools: Discover useful goods & low-carb management options on Amazon (Affiliate Link)

By the time I hit the three-week mark of my grueling hospital stay, I could physically feel my body making a dramatic recovery. The self-injections before meals and the constant blood sugar monitoring—which initially filled me with anxiety and dread—have now become a natural, essential part of my daily routine. Seeing my numbers steadily improve has given me the confidence to face my body and my health with a positive, proactive mindset.

【Quick Summary】

My muscle and kidney levels, which were looking incredibly grim, have plummeted back down, meaning I am officially out of the danger zone.
My blood sugar levels—essentially my body’s past report card—are still a bit on the high side, but compared to the sheer panic of when I was first admitted, they have improved massively.
Thanks to my daily insulin injections, my blood sugar has stabilized within a healthy, body-friendly range. I've come to see these shots not as a chore, but as a vital ritual that does the job my pancreas can no longer do.

🔍 The Pancreatic Cancer Scare: Looking Back at the Results

My blood test showed tumor markers above normal, with CEA at "6.5" and CA19-9 at "45". When doctors first mentioned a possible pancreatic cancer scare, my mind went completely blank with shock.
Fortunately, a prompt contrast-enhanced CT scan revealed no sign of tumors, conspicuous lesions, or abnormal blood flow around the pancreas.
It turns out the spiked levels weren't caused by cancer, but were likely a temporary reaction to severe high blood sugar and intense, systemic inflammation.
As my diabetes treatment progressed and the bodily inflammation subsided, the tumor marker levels naturally dropped, leading to a final diagnosis of negative (all clear).

📈 My Hospital Stats: Blood Sugar Trends and Vital Signs

My muscle enzyme level (CPK), which had skyrocketed to over 10,000 upon admission, plummeted to a perfectly healthy 58 U/L.
My rapidly deteriorating kidney function marker (creatinine) also dropped to 0.86 mg/dL—a massive sigh of relief.
My HbA1c (the report card for blood sugar over the last few months) stands at 7.4%. It's still slightly elevated, but it represents a dramatic improvement.
Thanks to daily insulin, my once-sky-high blood sugar has stabilized at a gentle, body-friendly 137 mg/dL.
While I still face the daily annoyance of the occasional painful prick when a needle hits a nerve, or minor swelling like a mosquito bite, I’m back to strength training and walking for rehabilitation without any issues.

🔍 Autoimmune Pancreatitis Suspicions and Lab Results

As mentioned above, my overall health is improving, and my blood levels are returning to normal. With my tumor markers dropping back to healthy ranges, the pancreatic cancer scare has been officially ruled out.

However, my blood work revealed IgG4 levels above "140 mg/dL" (or an equivalent abnormal elevation in immunoglobulins), a key marker for immune function. This raised concerns about possible Autoimmune Pancreatitis.
This is a specific condition where the immune system goes haywire and attacks the pancreas. Confirming a diagnosis requires not just blood data, but also visual confirmation of physical changes (such as sausage-like swelling) via imaging.
In my case, the contrast-enhanced CT scan showed no typical signs of abnormalities, such as diffuse enlargement or pancreatic duct narrowing.

Nevertheless, the suspicion of autoimmune pancreatitis still lingers, meaning I will continue with follow-up observation and re-testing.

Type 1 Diabetes: My Blood Sugar Battle and a Terrifying Pancreas Scare

Although my blood sugar levels slowly began to stabilize after starting insulin therapy, my ordeal was far from over. In fact, subsequent detailed MRI scans revealed that my 'pancreas was severely swollen,' raising suspicions of another serious illness. This time, I'll share details about this other alarming change in my body and the concerning test results.

[Swollen Pancreas and Suspected Autoimmune Pancreatitis]

Detailed MRI imaging of my internal organs revealed that my pancreas was generally enlarged (swollen and bloated).
My doctor informed me of the possibility of pancreatic cancer, as well as 'my own immune system mistakenly attacking my pancreas (autoimmune pancreatitis).
Hearing that the sudden onset of fulminant Type 1 Diabetes might be deeply connected to this severe inflammation of my pancreas, I was shocked to realize just how much my body was deteriorating.
Was it diabetes first, or pancreatitis? The cause of fulminant Type 1 Diabetes is often unclear, making it hard to say...

[Terrifying Abnormal Numbers]

Among my blood test results, one alarming number was CA19-9.
This value is typically used as a marker for cancer (tumor marker), with a reference range of 37.0 or less. However, I astonishingly registered an off-the-charts 401.0 U/mL.
I vividly remember my heart pounding when the doctor explained, 'It's unclear if this is a serious illness, or just a temporary spike due to your severely swollen pancreas.'

My Type 1 Diabetes Journey: The Shocking Diagnosis and My First Steps to Blood Sugar Control

📌 Related Support Tools: Discover useful goods & low-carb management options on Amazon (Affiliate Link)

Immediately after my emergency hospitalization, my doctor delivered news I never expected. It was the diagnosis of Type 1 Diabetes. Unlike the more common lifestyle-related diabetes, I learned that my body had completely stopped producing insulin, and the shock was immense. In this post, I'll look back at the definitive reason for my diagnosis and the dramatic changes in my blood sugar levels after starting insulin therapy.

Definitive Evidence: My Body Wasn't Making Insulin

Special test results revealing how much insulin my body was producing showed values significantly below the standard range.

📊 Insulin Secretion Capacity Test Results (Collected on Day 4 of Hospitalization)

Test Item Name	Your Measured Value	Reference Range	Unit	Condition / Explanation
C-Peptide (Serum)	0.16 L	1.0～3.5 approx.	ng/mL	This value clearly indicates a state where almost no insulin is being produced in the body (depletion state).
C-Peptide (Urine・24-hour collection)	15.12 L	15.0 - 133.0	µg/day	Shows extremely low insulin secretion over a 24-hour period.

💡 What These Numbers Mean

"C-Peptide (CPR)" is a substance released into the bloodstream in equal amounts with insulin when insulin is produced in the pancreas. Therefore, measuring this value directly reveals "how much insulin the pancreas is currently capable of producing on its own."

The current value of "0.16 ng/mL" indicates a state where independent insulin secretion has almost completely stopped, and this is the definitive evidence (numerical value) that leads to a confirmed diagnosis of "Type 1 Diabetes (or fulminant diabetes)," which differs from lifestyle-related diabetes.

These results clearly showed that my pancreas had completely lost its ability to control blood sugar.
Even in the initial urine tests upon admission, urine glucose was recorded at an abnormally high level of 4+, indicating that my body was overflowing with sugar.

Starting Insulin Treatment

Immediately after the diagnosis, insulin injections began, with medication taking over the role of lowering blood sugar in place of my own body.

To be continued...

Weekly Glucose Report (2026/07/04)

🛒 Check Health Management Items on Amazon

This is an affiliate link. We may earn a small commission if you make a purchase through this link, at no extra cost to you.

Weekly Blood Glucose Management Summary

Looking back at this week's blood glucose management, I was able to maintain high awareness toward the second half of the week and gradually bring in a positive wave. Although there were periods in the first half when the numbers were on the higher side, I feel it was an excellent opportunity to review my daily rhythm. While there were some gaps in the data, looking at the overall picture provided many clues to help me improve next week.

Particularly positive was the decline in average blood glucose levels leading into Friday and Saturday, showing a stable trend. On the other hand, I noticed a slight tendency for blood glucose levels to rise from late night to early morning. This could be influenced by dinner choices or meal timing.

For next week, with the goal of stabilizing overnight blood glucose levels, I plan to make some adjustments to the content and timing of my dinners. Without rushing, I will continue managing my levels comfortably at my own pace.

Weekly Trend Analysis

Reflecting on this week's trends, the overall average blood glucose level was 191 mg/dL, and the TIR (Time in Range, the percentage of time spent within the target range of 70–180 mg/dL) was 48.2%. Additionally, the CV (Coefficient of Variation), which indicates blood glucose variability, was 34.7%. It was pleasing to see that this met the target benchmark of 36% or less.

Looking at the graph, high blood glucose levels exceeding 250 mg/dL were prominent in the first half of the week (Sunday and Monday). However, toward the second half, the time spent within the green target range clearly increased. Note that there was a period of unmeasured data during this report window, making it impossible to confirm the week-over-week comparison from the image. Nonetheless, I want to focus on maintaining the positive changes seen in the latter half into next week.

Daily Summary Analysis

Looking at the daily data, there were distinct characteristics depending on the day of the week. The best day was Saturday (July 4), with a low average blood glucose level of 138 mg/dL and stable fluctuations throughout the day. Thursday (July 2) also showed a low average of 131 mg/dL, but since this was measured over only a short period during the night, it is reasonable to think that stability genuinely improved heading into Friday (average 156 mg/dL) and Saturday.

On the other hand, the highest glucose variability occurred on Monday (June 29), with an average blood glucose level of 246 mg/dL and a peak rising to 351 mg/dL. Sunday's average was also on the higher side at 230 mg/dL, which may have been influenced by meals over the weekend or changes in my daily rhythm at the start of the week. The stabilization of numbers toward the end of the week is likely due to the positive impact of regular weekday habits.

AGP Analysis

Analyzing the AGP (Ambulatory Glucose Profile), which summarizes the 24-hour blood glucose trend, highlights my patterns during different times of the day. Looking at the daily trend (the dark blue median line), levels are highly stable around 130–150 mg/dL from about 9:00 to 13:00, showing a tendency to stay within this range during the day. Regarding hypoglycemia risk, although the lower boundary drops slightly between 14:00 and 16:00, it did not reach dangerous hypoglycemic levels, which is reassuring.

A future area for improvement seems to be the late-night to early-morning period (around 21:00 to 5:00 the next morning). Blood glucose levels start rising after 21:00, likely post-dinner, and tend to peak between 3:00 and 5:00. Additionally, during this timeframe, the light blue shaded area (representing variability) widens significantly, indicating high daily fluctuation and elevated risks of hyperglycemia on certain days. This could be influenced by the carbohydrate content of dinners or pre-bedtime routines.

Key Successes of the Week

Average blood glucose levels decreased significantly in the latter half of the week (Friday and Saturday), increasing time spent within the target range.
The CV (Coefficient of Variation), which measures glucose variability, was 34.7%, staying below the target threshold of 36% and maintaining relatively stable trends.
Blood glucose levels were beautifully controlled within the target range during the daytime hours (9:00–13:00).
I safely got through the week without experiencing any severe hypoglycemia.

Areas for Improvement for Next Week

To moderate the overnight to early morning rise in blood glucose, I will adjust the portion of my dinner's main carbohydrate and balance my side dishes.
I will try eating dinner slightly earlier or doing light stretching before bed to help stabilize overnight glucose levels.
I will focus on proper sensor management and making scanning a habit to reduce missing measurement data.
While some metrics like GMI (Glucose Management Indicator) could not be verified from the images in this report, I will pay closer attention to handling the device so that all data is properly recorded next time.

Conclusion

Through this week's review, I have gained a very clear understanding of my blood glucose patterns and specific trends at different times of day. Building confidence from the wonderful stability seen in the latter half of the week, I will continue to gradually adjust my daily meals and lifestyle habits within a manageable range next week. Step by step, listening to my body, I will keep up the positive and enjoyable management of my blood glucose!

My ICU Nightmare: Surviving Fulminant Type 1 Diabetes and Ketoacidosis

📌 Related Support Tools: Discover useful goods & low-carb management options on Amazon (Affiliate Link)

I still remember the sheer panic that washed over me when the first blood test results came back after I was rushed to the ER. Even the doctors were stunned by the off-the-charts numbers. Let’s take a look at the terrifying, life-threatening data from the day I was admitted.

[The Shocking Blood Sugar Levels on Admission Day]

When I was first brought in, my blood glucose level was at a mind-boggling 828 mg/dL.
This was astronomical compared to the normal range of 70–109 mg/dL. It was a miracle I hadn't completely slipped into a coma.
On top of that, my triglycerides—which basically measure how thick and sluggish your blood is—were sitting at a terrifying 1146 mg/dL. *Note: My LDL and triglyceride levels had always been on the higher side, and I had been taking Atorvastatin 10mg for about three years.

[The Terrifying Numbers: When My Muscles Began to Fail]

My CPK levels, which skyrocket when there is massive muscle breakdown, had shot up to a staggering 11806 U/L.
Because of the sheer amount of waste from the damaged muscle fibers, my kidneys were struggling to cope. My blood urea nitrogen (BUN) rose to 63 mg/dL and creatinine hit 2.03 mg/dL—my kidneys were practically screaming for help.
To make matters worse, my CA19-9 level (an indicator of severe pancreatic inflammation) surged to 401.0 U/mL. It felt like multiple massive fires were raging inside my body all at the same time.

[Surviving the ICU: My Memories of Those Critical Days]

Fading consciousness in the ambulance: I have a hazy memory of being loaded onto the stretcher and put into the ambulance, but after that, everything goes completely blank. My wife later told me that my speech was so slurred that the paramedics asked her, "Does your husband always talk like this?"
Waking up to a web of wires: When I finally opened my eyes, I was in a hospital bed. I only found out later that it was the ICU. My arms were covered in a dizzying array of IV lines and blood monitors.
Delusional work anxiety: Apparently, in my confused state, I kept babbling to the nurses about needing to get to my job because I'm a designer, only to be gently told to calm down.
Hallucinations of a computer screen: There was a small, somewhat bright window in the room. Every time I closed my eyes, that square shape would expand and transform into a computer monitor, showing a desktop screen. I kept looping between opening my eyes to see the hospital room and closing them to see this hallucination.
Vision issues caused by high blood sugar: Once my consciousness returned, I tried putting on my glasses, but everything was incredibly blurry. An ophthalmologist examined my eyes but found nothing physically wrong. For a while after that, my ability to see far-off objects would fluctuate constantly depending on my blood sugar levels.
The harsh reality of the ICU: The patient next to me was coughing constantly and needed regular phlegm suctioning. I also remember hearing hospital staff discussing funeral arrangements nearby on my second day, realizing someone had passed away. It was a sobering environment.
Transfer to the general ward on Day 3: After about three days, my blood work stabilized enough for me to be moved out of the ICU and into a general ward.
