Noises keep coming from bowels, they are loud and constant. also i have diarrhea. i don't feel pain when the noises occur but i can feel the pressure?

Try changing diet?: Bowel sounds, even loud ones are normal. Gas may cause more sounds like this and may be worsened by carbonated beverages, vegetables, milk or a variety of other foods. Diarrhea usually means frequent ill-formed stools...this can commonly occur with irritable bowel syndrome, which may have the other symptoms you note. Overall I suggest you see a doctor, try simple foods until then. Get well
