There is no cure, but there are treatments available.


Another extremely common symptom of stomachaches, constipation occurs when stool cannot be passed through the digestive system quickly enough. It is often caused by a poor diet, and can be ameliorated by eating enough fiber. It can be painful enough to send people to the hospital, and usually causes bloating as well.

An infected appendix must be removed surgically as soon as possible, so you should seek emergency medical assistance.
