Almost there. Well Kinda

You mentioned a dislocated jaw, so did you get seen by a doctor and tell them everything you are taking plus what happened? The whole picture you gave points to high risk of fainting, but people usually do not lose memory of the event itself with a simple faint. Not remembering how you ended up on the floor does not fit the usual pattern. The fall plus the memory gap could point more toward a seizure or a concussion from the faint. Just guessing without full details. Big weight loss often causes low blood pressure when standing, and you clearly have that. If you have not already been checked out it might be worth doing, and it sounds like you should back off a little, stay on top of fluids and regular meals, and maybe get electrolytes checked.

As a GP this worries me. Passing out with zero warning signs is very concerning. It could be all the things you listed, but it could also be something else. No warning means you need to rule out heart issues and similar problems. You really should see a doctor. You do not sound well and skinny fat is not healthy. You need proper nutrition and some exercise. We should not blame every symptom on the glp meds or the other peptides. I see posts where people assume everything is from the meds but we can get sick for other reasons too. Go see your doctor and let us know how you are doing.

I do not know the US system well but here in Denmark you start with your GP who refers you if needed. If you cannot eat, please lower the dose or pause. The point of these meds is not to force feed. We need balanced meals every three hours or so, three main ones plus snacks, staying under TDEE. That is doable. I would spend a week eating more than my weight loss target. Eating on a schedule helps. An endocrinologist cannot do much if you are under eating. If I were your GP I would at least run an ECG, talk more about the episode, and do an exam to decide next steps. Normal blood tests do not rule everything out. Get better and eat.

Same thing happened to me today. My son who just finished med school called it orthostatic hypotension from low blood volume. Fancy way of saying drink more water. At least for me. Your situation may differ. It was not low blood sugar for me. I had sushi two hours earlier. Here are the numbers he checked with my home monitor. Left column sitting, right column right after standing after five minutes sitting. Big difference. So right now I am drinking a couple glasses of water.

This is interesting. Sorry you fainted and hope you sort it out, but I had never connected feeling faint with not drinking enough. I have never passed out but I do get lightheaded when standing up quite often and this might explain it. I will pay closer attention to these symptoms now.

Good reminder to watch protein, water and electrolytes. Skip a week if you have to and do not risk your health for a few pounds. Take care.

Some of those issues seem partly handled now, but you still need a proper medical check and the US version of a GP is the place to start. Ruling out more serious causes has to happen. Since you already show postural hypotension it makes sense to get a home blood pressure cuff. They are inexpensive and accurate enough. You can take several readings sitting then standing, write them down, and repeat on different days for an average. That gives you data and something to show the doctor. Know your pressure is not high before trying to treat the standing drop. People usually get electrolytes from food and added salt. If you are not eating steadily then lowering or pausing the glp dose is sensible. But if your blood pressure

Update. I have been slammed with work. Saw a cardiologist, new labs, wore a heart monitor for a month, and had an echo with bubbles. Heart is fine. Doctor says a subtype of POTS where standing makes BP and heart rate jump more than 40 points. Could be the brain adjusting to the weight loss plus all the stress on my body over the past year, and it might be long lasting. We will see after a year or so at stable weight. For now I am on a low dose beta blocker to stop the spikes and make daily life better.
