Ileitis, if it is a mild case, may heal spontaneously with a careful diet, but it is rare. If the inflammation is not completely cleared, the condition usually does not heal on its own. The most common cause of terminal ileitis is bacterial infection, which is caused by a poorly structured and unclean diet, resulting in decreased gastrointestinal function, slowed intestinal peristalsis, and bacterial attack on the ileum, resulting in mucosal congestion and edema in the intestine, increased glandular secretion, and inflammation, which requires anti-inflammatory medication. You can give haloperidol, levofloxacin tablets, berberine hydrochloride tablets for symptomatic treatment. At the same time, the diet needs to be adjusted and a good habit should be developed in general. The end of ileum is a good site for tumor, and should pay attention to review.
