Severe bloating when havent eaten for awhile. the bloating is painful and only goes when i eat but then get diarrhoea. happens every day?

Maybe your stomach: is reacting to your medications if they are new. Or you have some digestive issue which increased the bloating. Bloating generally means indigestion, from lack of digestive enzymes or normal flow of bowel "stuff". If you have gas, or pain under the right ribs, then gallbladder problem is suspected. Or you may just have poor function due to dietary changes. See a healthcare provider to figure.
