My best friend has been throwing up every morning since April 2018. She has had a colonoscopy, endoscopy, MRI, blood tests, and stool tests. When this began in April of 2018, she could not hold down food or liquids for weeks. She went in for a scope and they said she has 5 ulcers at the top of her stomach opening. They aren't peptic ulcers. Her doctor said she likely developed the ulcers from taking too much Advil, because she has debilitating cramps when she's on her period. He prescribed Prilosec to reduce stomach acid production and told her to start taking tylenol instead.
Since that diagnosis, her ulcers have not healed. She is very careful to eat bland, non-fatty foods. She does not take advil, drink alcohol, or drink anything caffeinated. With the aid of the acid reducer, she is able to eat, but she throws up every single morning. She has dropped a lot of weight, but her doctor does seem concerned and is not coming up with anything new to help her.
What could cause ulcers to last this long??
