stomach burns and it last for a few seconds. When they happens, I feel weak, I sweat and I feel nauses. This happens almost 5 times a day. When I eat, it will a few minutes after I ate and I will go to the bathroom and relieve myself. Ever since I started getting sick, I relieve myself 5 or 6 times a day. Can someone please tell me what is wrong with me and what I need to do.
