My Dad has been suffering with the pain at the upper abdominal since mid of February and most of the time, he's not able to release feces without the aid of stool softerners. His stomach is bloating and sometimes we can hear the sound of his stomach growling (sounds like water is running in the stomach).

Normally his stomach will start bloating again after meals and the discomfort comes back again after 1 or 2 days.

Any idea of what is happening with him?
