Many interconnected organs digest and absorb the food we eat and rid the body of waste from that process. But problems can arise.
* Heartburn is caused by a too-relaxed muscle at the bottom of the esophagus. (See "Eat small, eat early" on page 107.)
* Ulcers are caused when the lining of the stomach erodes. (See "A Whole Other Matter" on page 390.)
* You may have dyspepsia if a normal dinner makes you feel uncomfortably full. (See "Burn Baby Burn" on page 390.)
* Sometimes your bowels get in an uproar--gas, bloating, diarrhea--and you don't know why. To identify some likely culprits, see "Intestines" on page 183.
* The gallbladder shoots bile into the small intestine to help it break down food. But sometimes bile forms painful gallstones. (See "Scaling Back Your Risk" on page 152.)
* Your pancreas makes the hormone insulin, which helps your body absorb its food. Sometimes the pancreas stops making enough, and the result is adult-onset diabetes. (See "Finding Out Where You Stand" on page 306.)
