Hello there @kam1, and WECOME to Mayo Connect! I think if you take a look around this site you will find a lot of HOCM folks have some trouble with eating, eating large amounts, eating certain foods, and sometimes just eating in general. Why is that? I do not know! But I do remember having a really tough time after indulging in a meal consisting of all the "fun" stuff...hashbrowns, gravy, bacon, Thanksgiving food, those sorts of things. It would make me feel really crummy, my heart would race, pound like crazy and I would vow to not do that again. But I am a slow learner, so I did it again! In my mind, digestion takes energy and big meals take more energy and blood flow, which with HOCM is a struggle to provide. That is just my thought. When were you diagnosed with HCM? Has your cardiologist discussed a plan or course of treatment with you?
