What causes pain in the stomach after running?
Patient: Hi, I have had a gastric bypass last May and have lost 30kg and am now 87kg, 171cm tall.  I have been running regularly and am finding that my stomach really hurts when I have finished.mmimstill have quite a bit of flab.  Is there a way I can support it while running. Doctor: Hi.Thanks for your query.Read the history and understood your problem.It is good that you have undergone gastric bypass and have results of reducing 30 kgs. Flab will go slowly as the body will recoil it back slowly.You can use abdominal strappins meant for this purpose while supporting. Stomach can hurt a bit as there will internal scarring and fibrosis. Nothing to worry if there is no bloating, nausea and vomiting
