I’ve been taking Wegovy/Ozempic since the end of February for weight loss. I’m neither diabetic nor pre-diabetic, so I don’t have A1C values, etc… to compare. But… I’m about 20 lbs down so far, and I’m only on the 1 mg dose by this point.
From what I’ve read and talking to my doctor, semaglutide does a couple of things. One, it slows your GI tract, making you feel fuller longer. That’s a purely physical effect. The other main thing it does is regulate insulin levels- IIRC it causes your pancreas to secrete more when needed.
So from the inside, it makes you feel full longer, and you don’t eat as much because you’re already feeling full/not hungry. It also wipes out what they call “food noise”, which is the term for the sort of mental preoccupation with food that many of us have.
Before this stuff, I was constantly snacking on things, overeating too much of the ones I really liked, and generally thinking about my next meal with excitement and anticipation. Now it’s much more… sedate(?). Food just isn’t really on my mind most of the time- I don’t feel hungry, and I can leave chips and cupcakes alone without any sort of struggle. Or I can choose to eat them. But it’s not an urgent desire like it used to be. That’s probably the biggest change from the inside. I don’t feel any compulsion to clean my plate, or overeat because something tastes good. It’s weird, but welcome. I imagine that’s how most people operate actually.
Side-effects wise, I have been really lucky. The only real GI issues I’ve had were last week, believe it or not, and I’m still not entirely convinced they were Wegovy-related and not the result of something dodgy that I ate. The symptoms and outcome were a lot more consistent with having eaten something bad, in that it came on in the third week of 1 mg, lasted for about 5 days, and ended with a couple of bouts of diarrhea and almost immediate relief, with no side effects whatsoever since. Other than that 5 day period, it’s been side effect free for me thus far. The effects I did suffer were extreme heartburn, terrible sulfurous burps (like farting out of my mouth!), and gut cramping.
I kind of feel like the bad side effects most people get are related to the GI tract slowing down, and that probably amplifies any uncooperative stomach/gut issues people already have, like heartburn, constipation, gas, etc… Lucky for me, my guts have always been pretty agreeable, so I think that’s why I haven’t had much issue yet.
As far as the long term goes, I think the reason that the weight doesn’t stay off when people stop is because all that food noise rushes back, and suddenly they’re hungry again because their GI tract speeds up. I suppose that if you did it just right, you could parlay the medication into building better lifestyle habits, but I don’t know that those are going to hold up in most people in the face of that food noise and hunger. As far as I was concerned, I figured I was going to end up diabetic and taking something like this anyway in the next decade, so why not cut to the chase before things get that bad, and lose some weight using it? So I don’t really expect to ever go off of some sort of GLP-1 agonist type drug whether it’s weight loss or because I end up diabetic.
