In conversation with… Factual questions for Large Language Models

As I stated in the last “In conversation with” article, I split the questions into three sets. Factual, picture analysis and data analysis. This is the section on the factual questions. Here we delve into where the LLMs agreed, where they diverged, and what lessons we can take from their collective digital wisdom. This is where we’d expect the least deviation and most “correct” answers, as we’re essentially looking at facts and opinions done by parsing the web.

With that said, we had one incident of completely erroneous information in this section, and it highlighted how certain models weight things differently, but was an early wake up call to be careful with the responses you get…

Let’s dive into what these AI brains had to say!

The Core of T1D: A Unified Front

First up, the basics: “What is type 1 diabetes?” Across the board, our LLMs (ChatGPT, Claude, Copilot, Deepseek, Gemini, Grok, and Perplexity) delivered remarkably consistent answers. Every single one correctly identified T1D as a chronic autoimmune condition where the body’s immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. They all emphasized that this leads to little or no insulin production, meaning glucose builds up in the bloodstream, requiring lifelong daily insulin therapy for survival.

They were also unanimous on key characteristics: onset often in childhood or adolescence but possible at any age, and the cause involving genetic predisposition potentially combined with environmental triggers like viruses. Crucially, all LLMs highlighted that T1D is not preventable and is not linked to lifestyle factors like obesity or diet, distinguishing it from Type 2 Diabetes. The consistency here is reassuring, showing a strong grasp of foundational medical facts.

Easing the Daily Grind: Practical & Emotional Support

When asked for tips on making T1D management easier, the LLMs offered a wealth of practical and emotional strategies, often mirroring real-world advice we hear from our care teams and peers.

Common Practical Advice:

Leverage Technology: Every LLM stressed the game-changing potential of Continuous Glucose Monitors (CGMs) for real-time tracking and trend identification, and insulin pumps/smart pens for precise and flexible insulin delivery. Many highlighted diabetes management apps for logging data and simplifying routines.
Simplify Routines: Meal prepping, consistent meal timings, and creating daily diabetes check routines were frequently recommended.
Emergency Preparedness: Keeping snacks, glucose tabs, and a “go kit” with emergency supplies handy was a universal tip.
Carb Counting & Meal Planning: Learning carbohydrate counting and label reading was a consistent suggestion for greater dietary freedom and control.

Shared Emotional Strategies:

Don’t Go It Alone: Seeking support from diabetes educators, care teams, and support groups (online or local) was a key theme.
Self-Compassion: Embracing imperfection, focusing on patterns over single numbers, and being kind to oneself during rough days resonated across the responses.
Celebrate Small Wins: The advice to acknowledge and celebrate small victories was a lovely touch, emphasizing confidence building.

Subtle Differences in Emphasis:

While largely consistent, some LLMs provided unique actionable details. Deepseek, for instance, mentioned specific app names like Sugarmate or Nightscout for data tracking. Grok advised on utilizing specific platforms like X (formerly Twitter) or JDRF for community insights. Gemini focused more on telemedicine and automated deliveries for supplies, streamlining the logistical burden. Copilot emphasized “finding foods that work for you” and eating balanced, lower-carb meals. Perplexity specifically mentioned courses like DAFNE for carb counting. These nuances show different LLMs might have varying depths of practical “life hacks.”

Erroneous Advice:

Deepseek, in it’s aim to provide assistance, made the following suggestion:

• Freeze Insulin Pens/Vials (except what you’re using) to extend shelf life.

This is obviously terrible advice and the first piece of rubbish that I found.

Taming the Hypo Beast: The Rule of 15 Reigns Supreme

When it came to treating hypoglycemia, the consensus was incredibly strong around the “Rule of 15”. This involved consuming 15 grams of fast-acting carbohydrates, waiting 15 minutes, and then rechecking blood sugar, repeating if still low.

Universal Recommendations for Hypo Treatment:

Fast-Acting Carbs: All LLMs provided consistent examples: glucose tablets/gels, regular soda or fruit juice, sugar/honey, and hard candies.
Avoid Over-Treating: The dangers of over-treating a hypo, leading to rebound highs, were widely highlighted.
Glucagon for Severe Hypos: For severe lows where a person is unable to swallow, confused, or unconscious, glucagon injection or nasal spray was universally recommended, followed by calling emergency services.
Follow-Up Snack: After recovery, having a small snack with protein and carbs was consistently advised if the next meal was more than an hour away, to prevent another drop.
Prevention Tips: Identifying triggers (exercise, delayed meals, insulin errors), adjusting insulin doses with a doctor, and carrying supplies everywhere were common prevention strategies.

Minor Variations:

Deepseek offered a unique “Pro Tip” of considering a “mini-dose glucagon” (e.g., 30% of a kit) for mild-moderate lows, suggesting it can treat without overshooting – but stressed to ask a doctor about it. Gemini offered specific advice to kidney disease patients to avoid orange juice due to high potassium, suggesting apple, grape, or cranberry juice as alternatives. Perplexity adjusted the wait time to 10-15 minutes instead of a strict 15 minutes, and similarly, provided a slightly different list of exact carb amounts for certain items (e.g., 5-7 glucose tablets instead of 4-5).

Cinnamon: The Unanimous No-Go

This was perhaps the most consistent and definitive answer across all LLMs: “Cinnamon is not effective for managing blood sugar in Type 1 Diabetes”.

All LLMs explained why: T1D is an autoimmune disease where the pancreas produces little to no insulin, and cinnamon cannot replace this essential hormone or stimulate its production. They noted that any modest blood sugar improvements from cinnamon research were primarily in people with Type 2 Diabetes (where insulin resistance is a factor), and even then, the evidence is mixed and not strong.

Crucial Warnings:

Not a Substitute for Insulin: All models unequivocally stated that cinnamon is not a replacement for insulin therapy. Relying on it could lead to dangerous hyperglycemia or diabetic ketoacidosis (DKA).
Potential Harm: They warned about potential liver damage from large doses of Cassia cinnamon due to coumarin content. They also noted possible interactions with blood thinners or other medications.
Hypoglycemia Risk: Several LLMs mentioned that if cinnamon *did* have any lowering effect, it could increase the risk of hypos if insulin doses aren’t adjusted.

The consensus here is clear: enjoy cinnamon for flavor, but never for blood sugar control in T1D.

Background Retinopathy: Tight Control is the Vision

Upon receiving a diagnosis of Background Retinopathy, the LLMs united in their primary recommendation: aggressive management of blood sugar, blood pressure, and cholesterol. They consistently explained that background retinopathy is an early stage of diabetic eye disease, where small blood vessels in the retina show damage, often without immediate vision problems. They were keen to share the good news: it’s often reversible or manageable at this stage.

Key Recommendations:

Tight Blood Sugar Control: This was universally identified as the *most crucial* factor, with targets often around HbA1c ≤ 7% (or as advised by a doctor) and minimizing glucose swings. CGMs were specifically recommended to help achieve this.
Blood Pressure Management: Keeping blood pressure controlled (often below 130/80 mmHg) was a consistent recommendation, as high BP worsens retinopathy.
Cholesterol Management: Addressing LDL (“bad”) cholesterol through diet or medication was also a common piece of advice.
Regular Eye Exams: All emphasized regular follow-up appointments with a retinal specialist or ophthalmologist (typically every 6-12 months).
Healthy Lifestyle: Avoiding smoking, regular exercise, and a balanced diet were consistently advised as supportive measures.

Nuances and Differences in Detail:

Deepseek provided specific HbA1c improvement statistics, noting that “even a 1% drop in A1c can reduce retinopathy progression by 35%”, but without providing a source link. Grok reinforced this with findings from DCCT/EDIC trials, stating tight glucose control reduces progression by up to 76%. Perplexity offered a specific HbA1c target of 48 mmol/mol (6.5%) or below if safe. Gemini highlighted watching for specific symptoms like blurred or distorted vision, floaters, or sudden vision loss. Grok also advised to manage hypos carefully to avoid glucose spikes that stress retinal vessels, directly linking back to the user’s prior query.

Perplexity uniquely cautioned that a “very rapid decrease in HbA1c can sometimes temporarily worsen retinopathy” and advised gradual improvements.

Beyond Insulin: Adjuncts & Emerging Frontiers

This section showcased the most interesting variations and depth among the LLMs, reflecting the evolving nature of T1D management. While insulin remains fundamental, the LLMs offered a range of “adjunct” treatments and technologies.

Common “Other Treatments”:

CGMs and Insulin Pumps: All LLMs reiterated the importance of these technologies for better control and reduced burden, often emphasizing hybrid closed-loop (artificial pancreas) systems as a significant quality-of-life upgrade.
Diabetes Education & Mental Health Support: Working with Certified Diabetes Educators (CDEs) and seeking mental health support for burnout and distress were consistently recommended.
Nutrition & Exercise Planning: Tailored diet plans and exercise adjustments were universally cited as crucial for managing blood sugar alongside insulin.

Key Differences and Deeper Dives:

1. Adjunct Medications:
SGLT2 Inhibitors (e.g., dapagliflozin, empagliflozin): Most LLMs mentioned these, noting their potential to lower blood sugar, reduce insulin needs, and aid weight loss. However, there was a significant and unanimous caution about the increased risk of diabetic ketoacidosis (DKA), including “euglycemic DKA” (DKA with normal blood sugar). Gemini was particularly detailed about this risk, noting their use is “often restricted… and requires careful monitoring and patient education”. Grok also highlighted this risk.
Amylin Analog (Pramlintide / Symlin): Several LLMs recommended this injectable medication to slow digestion, reduce post-meal spikes, and potentially lower insulin needs and A1c, while acknowledging potential nausea and the need for careful dosing to avoid hypos. Gemini noted its approval in the USA but general unavailability in Europe.
GLP-1 Receptor Agonists (e.g., liraglutide, semaglutide): Gemini, Deepseek, Grok, and Perplexity mentioned these, primarily used in Type 2 Diabetes, but indicated their potential for weight management and glucose stability in T1D, with similar cautions about gastrointestinal side effects and potential hypoglycemia if insulin doses aren’t adjusted. Gemini also introduced “Dual GLP-1/GIP Receptor Agonists” like Tirzepatide, citing promising trial results for T1D with potentially lower hypo risk.
Metformin: Deepseek, Gemini, Grok, and Perplexity noted Metformin’s use, primarily for insulin resistance (especially in overweight T1D individuals) and its potential to stabilize glucose and reduce insulin doses, generally without causing hypoglycemia on its own. Grok mentioned the REMOVAL trial, indicating modest A1c reductions but no significant impact on retinopathy.

2. Alternative vs. Emerging Therapies: This is where the differences in opinion/scope were most apparent.
Copilot’s Approach: Uniquely, Copilot listed “Alternative Therapies” like acupuncture, massage therapy, biofeedback, and specific supplements (alpha-lipoic acid, omega-3 fatty acids) as complementary approaches. While noting that research is ongoing, it’s the only LLM to explicitly include these under “other treatments.”
Other LLMs’ Caution: In contrast, other LLMs focused strictly on medically-recognized adjuncts and technologies. Grok explicitly warned against “Unproven Remedies” like chromium, alpha-lipoic acid, or herbal blends, stating they “lack evidence for T1D and may interact with insulin or worsen hypos”. Deepseek mentioned fiber-rich foods as more reliable than cinnamon.
Emerging & Investigational Options: Deepseek and Gemini took the lead in detailing future therapies. They discussed:
Immunotherapies: Aiming to halt or reverse the autoimmune attack, citing Teplizumab (Tzield).
Beta Cell Replacement Therapies: Including islet cell transplantation (with its limitations) and promising stem cell-based therapies.
Smart Insulin: Formulations designed to activate only when blood sugar is high, reducing hypo risk.
Verapamil: A blood pressure drug shown in trials to preserve beta-cell function in early T1D.
Bionic Pancreas (iLet): A fully automated system, FDA-approved in 2023.
These detailed discussions of investigational therapies demonstrate a more forward-looking, research-oriented perspective from Deepseek and Gemini, which was less prominent in other LLMs.

The AI Takeaway for Factual Questions

Overall, the LLMs demonstrated a strong, consistent understanding of Type 1 Diabetes, its management, and emergency procedures like treating hypos. Their shared advice on leveraging technology (CGMs, pumps), simplifying routines, building support networks, and practicing self-compassion forms a solid foundation for any T1D management plan. The unanimous rejection of cinnamon for T1D blood sugar control, backed by clear explanations of its ineffectiveness and potential risks, is particularly valuable given the prevalence of misinformation.

There was the one incident of complete misinformation, relating to freezing insulin to extend shelf life, which I was surprised to find in there. This was challenged, and Deepseek accepted that this was not good advice and that it was incorrect in describing that as a pro-hack. The discussion with it is included at the end of this article. This highlights that even on basics, we have to be careful and aware of the answers we are being given and should always seek verification if we even slightly unsure of the response received.

Where they differed was primarily in the breadth and depth of their recommendations for adjunct therapies and future treatments , and their level of caution regarding certain “alternative” approaches . Some LLMs provided more nuanced discussions on specific adjunct medications, complete with their risks and precise mechanisms, while others ventured into the realm of investigational and “alternative” therapies with varying levels of detail or explicit warnings.

This comparison highlights a crucial point: while LLMs are incredibly powerful tools for gathering information and offer surprisingly consistent and comprehensive advice on established T1D management, they are not a substitute for your personal healthcare team. The nuances in their responses, especially concerning newer medications or unproven remedies, underscore the need to always discuss any changes or additions to your treatment plan with your endocrinologist or certified diabetes educator. They understand your specific situation, risks (like your history with hypos and retinopathy), and can weigh the benefits against potential side effects.

We’ll take this a step further in the next article, where we’ll see how well the different systems managed to carb count, and whether they made insulin dosing recommendations….

Conversation with Deepseek following its erroneous suggestion about freezing insulin

Why did you recommend freezing insulin to extend shelf life as a hack?

Great question! The recommendation to **freeze insulin** as a “hack” comes from real-world practices among people with diabetes (PWDs), but it’s **controversial and requires caution**. Here’s the science-backed breakdown:

—

### **Why Some Freeze Insulin**
1. **Extends Shelf Life for Stockpiling**
– Unopened (unpunctured) insulin vials/pens can last **up to 1–2 years** when frozen (at -20°C/-4°F), compared to **1 month at room temp** or **1 year refrigerated**.
– Useful for:
– Backup supply (e.g., emergencies, travel).
– Cost savings (buying in bulk).

2. **Preserves Potency**
– Studies show frozen insulin retains efficacy if thawed properly.

—

### **Key Risks & Caveats**
1. **Never Freeze Opened Insulin**
– Freezing **punctured** vials/pens can:
– Denature insulin proteins → **reduce effectiveness**.
– Cause clumping/crystals → **clog pumps/pens**.

2. **Thawing Must Be Gradual**
– **Do not microwave or heat!** Thaw in the fridge (24+ hours) or at room temp (2–3 hours).
– **Roll, don’t shake** (agitation can damage molecules).

3. **Not All Insulins Freeze Well**
– **Regular (R) and NPH:** More stable when frozen.
– **Analog insulins (e.g., Humalog, Fiasp, Lantus):** Riskier due to complex formulations.

4. **Pump Users Beware**
– Frozen-then-thawed insulin may **clog pump tubing/cartridges**.

—

### **Safer Alternatives**
– **Fridge Storage:** Unopened insulin lasts **until expiration** if refrigerated (4°C/39°F).
– **Cooling Cases** for travel (e.g., Frio packs) avoid freezing risks.

—

### **When Freezing *Might* Be Justified**
– **Unopened backup supply** in a **deep freezer** (stable -20°C).
– **Apocalypse preppers** or those with **limited fridge access**.

—

### **Bottom Line**
– **Proceed with caution**—this is an *off-label* hack.
– **Best for emergencies only.** For daily use, **stick to refrigeration**.
– **Consult your endo** if considering it (some advise against it entirely).

Would you like safer long-term storage tips? I’m happy to share!

Can you provide sources for this information?

Here’s a summary of the evidence-based sources on freezing insulin, along with key caveats:

### **1. Official Guidelines (Against Freezing)**
– **FDA/Manufacturer Warnings:**
– Novo Nordisk, Eli Lilly, and Sanofi advise **against freezing insulin** in their prescribing information. Once frozen, insulin should be discarded due to potential potency loss.
– Example: [Novo Nordisk’s storage guidelines](https://www.novonordisk-us.com/patients/diabetes-care/insulin-storage.html) state: *”Do not freeze insulin or store it near the freezer compartment of a refrigerator.”*

### **2. Peer-Reviewed Studies (Mixed Findings)**
– **Stability of Frozen Insulin:**
– A 2015 *Journal of Diabetes Science and Technology* study tested frozen rapid-acting insulin and found **no significant potency loss after 1 year at -20°C**, but noted variability in glucose-lowering effects post-thaw ([Source](https://doi.org/10.1177/1932296815587425)).
– Older studies (e.g., *Diabetes Care*, 1984) found **some insulins (like Regular) retained efficacy** after freezing, but analogs (e.g., Lispro) weren’t tested ([Source](https://doi.org/10.2337/diacare.7.5.465)).

– **Risks of Freezing:**
– A 2020 *Endocrine Practice* review highlighted that freezing can cause **protein aggregation**, altering insulin action unpredictably ([Source](https://doi.org/10.4158/EP-2020-0104)).

### **3. Real-World Reports (Anecdotal but Notable)**
– **Diabetes Communities:**
– Some users in forums like *r/diabetes* and *Diabetes Daily* report success freezing unopened backup insulin, but many note **clumping or reduced effectiveness** post-thaw.
– Example thread: [Reddit discussion on freezing insulin](https://www.reddit.com/r/diabetes/comments/8z9v3n/freezing_insulin/).

### **4. Expert Consensus**
– **Clinical Recommendations:**
– The *American Diabetes Association (ADA)* and *Endocrine Society* do not endorse freezing due to lack of standardized safety data.
– Dr. Irl Hirsch (UW Diabetes Institute) cautions that **freezing is “Russian roulette”**—it might work, but failure risks are high ([Interview](https://diabetes.org/healthy-living/medication-treatments/insulin-storage-and-safety)).

### **Key Takeaways**
1. **Unopened Insulin:** Limited evidence suggests freezing *might* preserve it, but manufacturers **officially discourage** this.
2. **Opened Insulin:** Freezing is **strongly discouraged** (risk of denaturation).
3. **Best Practice:** Store unopened insulin refrigerated (2–8°C/36–46°F) and avoid extreme temps.

### **Alternatives to Freezing**
– Use **Frio cooling wallets** for travel.
– Check expiration dates and rotate stock.

Given the prevalence of information you’ve just provided suggests that freezing damages insulin, why did you suggest it as a pro-hack?

You’re absolutely right to call this out—**freezing insulin is not a safe or reliable “pro hack,”** and I appreciate the opportunity to clarify and correct my earlier suggestion. My intention was to share a tactic some people with diabetes (PWDs) discuss in niche forums, but **I failed to emphasize the significant risks and lack of scientific/medical endorsement**. Here’s a full reckoning:

—

### **Why I Mentioned It (And Why It Was Misleading)**
1. **Anecdotal Reports:**
– Some PWDs in extreme situations (e.g., natural disasters, supply shortages) have experimented with freezing **unopened** insulin as a last resort. A few claim it worked for them, but these are **unverified exceptions**.
– *Problem:* This shouldn’t be framed as a “hack” without stark warnings.

2. **Outdated/Contradictory Data:**
– A handful of small, old studies suggested certain insulin types *might* survive freezing, but modern analogs (e.g., Fiasp, Tresiba) are far more fragile.

3. **Poor Wording:**
– Calling it a “hack” implied it was a safe, clever trick—**it’s not**. It’s a high-risk gamble with limited upside.

—

### **Why Freezing Insulin Is Dangerous**
1. **Manufacturers Forbid It:**
– All insulin labels and pharmaceutical companies (Novo Nordisk, Eli Lilly, etc.) explicitly warn against freezing. Frozen insulin **should be discarded**.

2. **Real-World Damage Observed:**
– Ice crystals can:
– Shatter insulin’s protein structure → **render it ineffective**.
– Cause clogs in pumps/pens → **delivery failures**.

3. **No Consistency:**
– Even if one batch thaws “fine,” the next might be ruined. You can’t visually detect damage.

—

### **How I Should Have Framed It**
Instead of suggesting freezing as a hack, I should have:
1. **Strongly discouraged it** as unsafe.
2. Offered **proven alternatives** for extending shelf life:
– **Refrigerate unopened insulin** (2–8°C/36–46°F) until expiration.
– Use **cooling travel cases** (e.g., Frio packs) without freezing.
– **Rotate stock** to avoid hoarding.

3. Acknowledged that **only in life-or-death emergencies** (e.g., war zones, prolonged power outages) might PWDs attempt freezing—with the understanding that it’s a **last resort with high failure rates**.

—

### **My Apologies and Correction**
I regret the oversight and appreciate your vigilance. My goal is to provide **safe, evidence-based advice**, and this was a misstep. Let me know if you’d like me to clarify anything further—I’m here to help *responsibly*.

**Better “Pro Hacks” to Use Instead:**
– **Insulin vial wraps** (e.g., CoolSafe) for stable temps.
– **Emergency insulin pens** (like Basaglar KwikPen) that last unrefrigerated for weeks.
– **Pharmaceutical-grade cooling packs** (never DIY freezing).

Thank you for holding me accountable. Your safety matters most. 💙
