Patients with diabetes may also have diarrhea, especially when features of autonomic neuropathy are present. Laboratory testing Screening tests for HIV infection should be considered in patients with chronic diarrhea. This infection commonly causes diarrhea, which can be the result of a coexistent gastrointestinal infection that requires specific therapy. Additionally, endoscopic examination of the colon to evaluate for inflammatory bowel disease may be indicated in a patient with chronic diarrhea. Treatment Treatment of IBS may be challenging, since the disorder is chronic and has a natural history of exacerbations and remissions.
Patient education Developing a good relationship with patients is important.
In addition, patients should be told that IBS is a chronic disorder that cannot be cured and should be reassured that it does not lead to life-threatening disease or physical impairment. Symptomatic therapy Symptomatic therapy for gastrointestinal symptoms is directed at the specific complaint. Constipation may be relieved with a diet high in fiber and fluids and sometimes requires the addition of fiber supplements. Since symptoms are chronic, the use of laxatives should be avoided. Patients with predominant symptoms of diarrhea also respond to fiber supplements, although antidiarrheal drugs, such as loperamide hydrochloride, may also be necessary.
