I have extreme bloating above my belly button for several hours after i have eaten, there is no pain, i have heartburn often.

Bloating: You may have indigestion or acid reflux; try over the counter antacids or gas relief meds. If no improvement, see your doctor to rule out a gastric emptying or digestive abnormality. Avoid lying down for 2 hours after a meal and drink 8 ounces of water with your meal.

Indigestion: you are having indigestion watch what you eat stay away from greasy and spicy food avoid red meat and raw vegetables you might be having irritable bowel syndrome as well take anti a it with gas x in it keep your bowel regular hydrate well and exercise sodas and pops are not fluid only water and juices no better talk to your doctor good luck

Bloating: You could have reflux as you describe heartburn already. It also could be your gallbladder. The best thing to do is to be evaluated with an ultrasound

Possibly due to acid: Your symptoms may be due to acid, especially since you mention heartburn. Try 2 weeks of omeprazole 20 mg once a day- taken 1/2 hr before a meal.

Also consider possible food in tolerance to gluten or lactose, or use of artificial sweeteners.
