I am a 3 year survivor of breast cancer but for the past year have had to take zantac or another antacid every day due to "indigestion". It does not burn - but I can have two bites of food and feel so full and bloated I can't eat more. I feel bloated and miserable. I have not lost weight - so have not paid a lot of attention until recently when the symptoms seem more intense and I'm finding myself taking both the zantac and additional tums and still feeling miserable. I have eliminated meals - because I'm so uncomfortable. I just recently went to my Oncologist - for normal blood work, etc... and everything looked good. I am wondering if this is just due to getting older (56) and needing to adjust my diet or if I should be concerned.
