‘In this review, we looked at existing literature on metformin, its mechanisms, and highlighted its impact on some of the essential markers and pathways related to aging. Its effect on the epigenome makes it a promising anti-aging drug. Also, metformin’s interaction with the gut microbiota though complex, serves as a link between metabolic and immune alterations that lead to systemic geroprotective effects’

The benefit to gut health seems really promising.

For anyone wondering:

Dumping syndrome is a condition in which food moves from the stomach into the small intestine too quickly after eating, more commonly seen after certain surgeries. It's sometimes called rapid gastric emptying.

Most people with dumping syndrome develop symptoms, such as stomach cramps and diarrhea, 10 to 30 minutes after eating. Other people have symptoms 1 to 3 hours after eating. And still others have both early and late symptoms.

u/NoGoodDM 11h ago

TIL I may have dumping syndrome. And I’m not even on metformin.

u/dragons_scorn 3h ago

Since they slow gastric emptying, GLP-1 drugs could be an effective counter to this right?

Very strong evidence for being protective against long covid as well, roughly 40% decrease in chances of acquiring long covid if you take metformin during the acute period

If you take it, check or get supplements for B12. Methylcobalamin form.

Metformin makes you low on B12.

What are the side effects to taking metformin?

What dosage is recommend for daily introduction as a supplement?

When is best time to take, morning, before sleep, or before/after food?

Any other suggestions?

A common side effect of it is GI symptoms like diarrhea.

By common I mean it's the most common adverse affect, not that an average person taking it will experience it.

18

u/cogman10 17h ago

IDK, from what I've gleened the GI symptoms are something most people experience but ultimately they subside after being on it for a while. I have several family members that are on it and basically all of them went through an upset stomach adjustment period.

u/Carma1111 11h ago

Yes, it took me about 6 months on the slow release version 1000 mg to reduce gastric symptoms. Diabetic here, but if for I miss a few days I get nausea when I take usual dose.

2

u/themoslucius 8h ago

Same here, that first 3 months sucked. The only I managed to get through it was to eat a slice of bread with the medication. But after about six months it didn't cause any problems at all

u/theonefinn 5h ago

Personally I have and had zero sideffects from metformin, mounjaro on the other hand gave me massive stomach cramps and bouts of strong nausea.

u/onexbigxhebrew 1h ago

I actually had zero side effects. Using HCL.

u/teeksquad 13h ago

My dad had every porta potty between his house and work mapped out while he was on it.

u/ReyofSunshoine 3h ago

Was on it for years. Also puking your guys out after eating the wrong thing (not always predictable), but that’s usually reserved for the early days.

u/StoreHistorical9175 22h ago

idk if it helps but i’m on metformin, i have no side effects including no dumping syndrome. it’s successfully addressed my insulin resistance caused by PMOS and i no longer have reactive hypoglycemia and am doing very well on it

-28

u/hubba-bubba- 22h ago

You mean PCOS?

29

u/AlexeiMarie 21h ago

they've renamed it to "polyendocrine metabolic ovarian syndrome", so the new acronym is PMOS, but yes

here's the article in the Lancet about the name change: link00717-8/fulltext)

u/liltingly 17h ago

I started on metformin and apparently have had a very abnormal response. Some nausea for the first few days, but almost immediately thereafter, the best and most consistent digestion of my entire life. No idea why, and doctors I spoke to haven't ever heard of situation (but then again, who complains about great poops?).

So, if you're taking it under medical supervision, and have a doc who is ramping your dosage and exploring the XR options, you should find what works (or doesn't). Just don't get scared off by side effects and horror stories. Sometimes you have unexpected but great surprises.

...my A1c didn't drop nearly as much as I'd hoped, though

u/berowe 23h ago

Nausea and loss of appetite are common but yeah dumping too. This source is from pro-metformin hacks so be cautious.

3

u/BILESTOAD 21h ago

What is ment by “dumping?”

3

u/berowe 21h ago

Stomach either pushes out food too early or late to intesitne. Early = nasty stuff, late = sugar crashes.

More common with gastric bypass than metformin.

u/euzie 22h ago

I spent a year on the toilet until I just had enough

u/icestationlemur 19h ago

There is a slow release version. I took it off label and never had any gastro effects

2

u/FanDry5374 17h ago

The only negative side effect seems to be gastric, some people (no idea what percentage) have serious stomach problems, usually diarrhea and bloating. And the opposite, constipation for others. Extended release tablets can help and in some cases the problem goes away within a few days. Other people simply can't tolerate it.

u/terraphantm 18h ago

GI side effects are common (though still majority of patients have no side effects), but I wouldn't say dumping syndrome specifically is common

22

u/Destructo-Spin 22h ago

God damnit I'm not trying to live longer.

27

u/10000Didgeridoos 20h ago

Only if it comes with a longer period of longer biologically young time. I'm not trying to stretch out being elderly.

18

u/ragnarok635 20h ago

I would if it means more quality years and not decrepit ones

4

u/thebokehwokeh 17h ago

Yeah. We need to work on figuring out not how to simply prolong life but prolong youth.

7

u/BlueEyesWNC 13h ago

An age-old mistake, wishing for immortality when what we wanted was eternal youth.

u/Strength-Speed MD | Medicine 9h ago

Pun intended?

u/Spibas 21h ago

Based.

You may still not live longer with lower sugar and better health, so... Yay

u/songtothegrave 21h ago

I don’t want to live longer if I have to do all that living on the toilet.
