question: Hi my stomach swells up and I also have a tired sort of gritty feeling behind my eyes for some period of time over possibly the course of the week I start to feel as if my body inside is shaking and I have mild anxiety attacks.over this period of time I have swollen stomach slightly painful sometimes not always and after my anxiety attack I am really tired.throughout I have very low energy.I have had numerous blood tests are which of showed nothing and also I have had blood tests for a thyroids problem botChatDoctore back as ok.my diet is ok but not great and found last year when this happened I ate extremely healthy and it went away.i understand that I have to keep a good diet of fish veg and fruit ect but wonder what is happening to make me feel like this.i occasionally take omeprazole for acid indigestion could indigestion be the problem? Or just a symptom of a problem?
