Could Reta be causing low blood sugar?

Hichewgoddess said:

I'm only on week 4 of Reta, taking 1mg each week. Roughly 24 hours in, my blood sugar seems to fall. I feel dizzy and nauseous, and I get faint. I'm guessing that's the cause, since a bit of candy or something sugary plus water appears to sort it out. I do eat carbs, I keep up with my water, and I take electrolytes too (1 packet of liquid IV daily), yet I still feel like I have to be extremely cautious. Is this hypoglycemia? Or could it be low blood pressure from not getting enough water/electrolytes?
There was one occasion when I felt somewhat lightheaded, so I used that moment as a reason to have something sweet. I continue to have sugary snacks, although I have reduced them a lot. My typical lunch is a light meal plus a snack, and for dinner I have a moist meal with a snack, and occasionally I'll have 2 snacks. Right when I began, I lowered my sugar intake considerably, so it was simple for me to connect the way I was feeling to a need for sugar—or at least, that was my assumption.
 
I typically take in larger servings of carbs both before and after my training sessions. It's been 3 weeks so far, and up to this point I haven't experienced any drops.

Is your blood glucose being checked with a CGM, or are you doing fingerstick readings every so often? From what I've seen, the numbers shift at different points during the day.

Every day I go through 3-4 packets of electrolytes 😂
 
There's a lot of fear, uncertainty, and doubt in this thread:

"Asymptomatic hypoglycemia" is not something worth worrying about. In fact, this is partly why doctors tend to resist prescribing CGMs to people without diabetes (and even to many with type 2 diabetes), even though I think it would be a great thing. They know their patients will overinterpret the readings and begin acting as though they have type-1 diabetes (for example, eating sugar snacks whenever the number drops, and making other strange choices to flatten the figure displayed in their phone app). You're also mixing up the usual early GLP symptoms with hypoglycemia. I had those symptoms at the start too. I've used a CGM for years. On reta my blood sugar dropped. During dose escalation it often sat in the 50-60 mg/dL range. That's not unusual. Ordinarily I'd need to fast for 4-5 days before it would sit in that range.

If you inject insulin and take sulfonylureas, then you should monitor your blood sugar and do things like eat a sugar snack when you notice it dropping. Apart from that, unless something very unusual is going on with you, acting like a type-1 diabetic won't do you any good.

No one here, as far as I can tell, is worried about hypoglycaemia without symptoms. Honestly, if I could walk around with asymptomatic low blood sugar for years, I'd be delighted, since the link between a raised HbA1c and atherosclerotic burden is well established.

Claiming with such certainty that hypoglycaemia symptoms cannot occur when someone starts retatrutide — and that every complaint is simply 'normal initial symptoms' — takes a fair amount of nerve. And remember, GLP1 drugs were originally developed with the explicit aim of bringing blood glucose down in T2DM.

Experiencing hypoglycaemia symptoms does not require a T1DM diagnosis. How low someone's glucose has to fall before they notice symptoms varies a great deal from person to person — this is what's called hypoglycaemia awareness.

I'm glad 50–60 mg/dL felt fine for you, but presenting your own experience as if it were universally safe or typical for everyone else is probably not the right move.

I never said "can't." What I meant is this: when someone begins injectable insulin or a sulfonylurea, doctors give a hypoglycemia warning for a reason, yet no such warning accompanies the start of a GLP. Why? Because symptomatic hypoglycemia is not a frequently seen risk tied to GLP therapy, unless the same individual is concurrently using injectable insulin or a sulfonylurea.

That said, once in a blue moon a person's metabolism is deranged enough that introducing a GLP tips them into symptomatic hypoglycemia, just as once in a blue moon someone loses their vision after starting a GLP. Both events are uncommon, and with hypos the individual typically already knows it is an issue for them before ever starting the GLP, since it has been a longstanding problem in their history.

What you are actually doing is over-interpreting the numbers on your CGM. Even without feeling light headed, clammy, or passing out, you have talked yourself into believing you are in danger. As a result, you misapply type-1 diabetic rules of thumb about hypoglycemia and treat 50-60 mg/dL as a dangerously low blood sugar, even though that level is commonly reached during an extended fast and a substantial number of normal healthy people will show it as a reactive reading after eating, all without those symptoms.

Here is the piece you are missing: a type 1 diabetic will sweat a 50-60 mg/dL reading not because the number itself causes harm, but because of the direction it signals. When their blood sugar is moving downward AND their body cannot self-correct, then by the time the CGM displays 50-60 mg/dL their true blood sugar is probably already beneath that. And because their body cannot hormonally self-correct, acting right away matters; waiting until it drops to a harmful level means it is already too late to respond.

So once more: anyone may wear a CGM and role-play being a type 1 diabetic, but in the overwhelming majority of cases it is not needed.

Armchair expertise on the internet carries risk even in ordinary situations, and that risk is especially high when the subject is drugs of this kind.

All the best

What strikes me here is that the majority of physicians I run into zero in on trial-derived clinical evidence and would write off personal accounts (such as your CGM readings) as "weak." Your evident enthusiasm for N=1 anecdotal reports stands out as unusual (and frankly I wish a greater number of your colleagues shared that inclination, and I think you deserve praise for it, though that complaint belongs elsewhere).

Just wondering, have you looked into how Lilly addresses this matter across their phase 2 and 3 retatrutide trials, and whether any hypoglycemia prevention steps (such as CGM usage) were put in place? Phase 2 trial results are out there, and we also have accounts from people enrolled in phase 3 trials. The logic would be that if this were even somewhat frequent, phase 2 trials ought to have flagged it, and failing that, phase 3 trials would have.

Should you dig into it, you will find a trial in which Lilly combines retatrutide with CGM use and.... (drumroll).... it sits within their 3rd TRANSCEND-T2D trial, which centers specifically on type 2 diabetics who are ON INSULIN.

That said, this is not proof that no hypoglycemia risk exists (and as I emphasized in my previous reply, I am not claiming zero risk). What it does do is lend strong backing to the notion that any such risk would be an edge case rather than a frequent side effect.

I don't have diabetes, but my job gives me access to what is essentially an endless stock of continuous glucose monitors (CGMs), and I used them in the past to follow my BGLs while off retatrutide. My readings usually sat in the 6-8mmol (108-144 mg/dl) range.

I've been raising my Reta dose over several weeks and have now been steady at 4mg for the last 3.

This week I put a CGM back on, and here's what I found.

- Roughly 12 hours after my weekly retatrutide injection, I had a notable low of around 3mmol/L. No symptoms.

- These days I generally sit near 4mmol/L, though I also spend a large amount of time in the 3.2-3.7 range. That pattern shows up most reliably during working hours, when I might go 8-10 hours without actually having a chance to eat.

- I haven't had symptoms from a low yet, but at these lower levels I do feel at minimum somewhat tired and foggy, plus hungry

A few things I take from this personally

- For my glycemic control, Reta is VERY GOOD — that's an average drop of 2mmol compared with before

- Even so, I believe hypoglycaemia risk on a GLP1 doesn't get discussed enough

- There's probably a group of people like me whose BGL is already 'borderline' without any medication, and they could be at risk of hypoglycaemia on a GLP1 without realising it. It matters that every trial so far selected people who are pre-disposed to insulin resistance (I.e BMI >31). By contrast, anyone can obtain it on the grey market, and that group isn't well represented in trials.

- Given the chance of a genuine symptomatic hypoglycaemic event, I definitely don't feel safe going above 4mg. For comparison, where I live T1 diabetics are legally required to test their BGL before driving and can't drive unless it's >5mmol/L.

- While on this medication it's important to eat at least small meals across the day; I'm not convinced that prolonged intermittent fasting is very safe on it.

- I do question whether some retatrutide side effects people report could be accounted for entirely by ongoing hypoglycaemia

However, giving patients treatment isn't what I do. What I do is share my take on pharma products.

Where your reasoning goes wrong is that you assume blood sugar works on a simple "lower is bad" rule the moment a person drops below 70 mg/dL. The only time lower is bad is when SYMPTOMS follow from it. That was the whole basis of my first critique of your FUD: you weren't having hypoglycemic SYMPTOMS. Distinguishing the two is straightforward (with a CGM on, like you had) because you can check whether the symptoms line up with the stretches when blood sugar falls and disappear the rest of the time. Actually, a CGM isn't even required for that.

Constant fatigue or tiredness isn't hypoglycemia. That points to GLP side effects. Symptoms that shift and fade minute to minute, hour to hour, at least could plausibly tie back to hypoglycemia. Before someone reaches that stage, the whole question is a moot point.
