I had a colonoscopy and endoscopy and being the first time I was scared too. I think the prep was worse than the procedure tbh but it's just a lot of toilet trips actually. The procedure is quick and easy and I was asleep for it. Woke up moments later with good news that they found nothing. I too had lost a lot of weight so there was some worry there. Turns out it was all due to anxiety. I had no ill effects afterwards. Went straight home with huge relief. They told me it's a good thing to have this procedure so if there's anything that shows up they can address the problem immediately. The anticipation is the worst, I know. I got lorazapam to take for the week before so I could stay calm.⁷
