Do you now take medicine for the slight hypertension and does your stomach get upset after taking it? I would suggest you lose weight, avoid real salty food and take any medicine your doctor wants you to take. If you get side effects talk to your doctor as often a change in meds can solve the problem. You sound like you are very anxious to me. I would avoid coffee and strong tea and see if that helps your stomach. When I get very upset I get an upset stomach (among other things). If the anxiety continues you might want to try some medicine for anxiety like xanax or prozac. Maybe just talking with your doctor or nurse is all you need.
