There is no way to tell you what kind of surgery you had but it’s easy to say vitamin deficiency is normal with surgery. I need to get vitamin iv’s and iron Iv’s frequently, I also need vitamin d during the year. It has made me feel so much better. I also was diagnosed with celiacs and that has helped me feel better. They say if intestines were taken at all it’s highly likely you can develope celiacs. I live in Michigan and have an amazing doctor. She is a DO but practices mostly wholistic, look for one where you are. They look more at vitamin and hormone levels
