Sorry for your dilemma. Not being able to eat is quite scary. I am wondering, did you use excessive over the counter pain medications like ibuprofen, Aleve, Advil and the like? If so, you may have destroyed your stomach and gut which maybe the cause of your inability to eat. I did this myself due to life-long migraines. I got down to 103 at age 60. I was 138. Did you have an endoscopy? Without the endoscopy, I would never have known the cause of my severe weight loss. The medications made my stomach produce too much collagen to protect it from burning itself but then I could not eat, nor absorb nutrients. Please consider the possibility. I am not a medical doctor, but it appears they may be overlooking a rare disorder which is on the rise. Collagenous Gastritis is the diagnosis I have. My best to you in finding the cause. Don’t wait....
