hi, i have severe bloating and trapped gas, occasionally with cramps. lots of noises from large intestine, like clicking and rumbling. every morning must have a bowel movement immediately otherwise severe discomfort continues all day. stools are always pebble-shaped with mucus, easy to pass. occasionally there is constipation or diarrhea. passing excessive mucus at times during a bowel movement (on its own, not stuck to stools) is very common. i'm 33 years old, 5' 9" and have a healthy diet and no other medical issues. please help!
