My stomach feels heavy and when i eat i feel sick no pain happening a couple of weeks now can't see dr no money what could it be?

Heavy Stomach: If you regularly feel sick after eating and feel you are constantly bloated or full you may have issues with your gallbladder. You should see your doctor to have labs done to check your liver and pancreatic enzymes and an abdominal u/s. I see you are taking phentermine, fluctuations in weight can cause gallstones.

Gi issues: You could have reflux disease, gallbladder problems or constipation. Try some otc zantac/pepcid or Prilosec and see if that helps. Regulate your bowels with fluids and fiber. If vomiting blood or blood in stool go see your doctor. Get on internet to sign up for health insurance.
