Following the relief of constipation, maintenance with adequate exercise, fluid intake, and high-fiber diet is recommended. Treatment
A limited number of cases require urgent medical intervention or will result in severe consequences.The treatment of constipation should focus on the underlying cause if known. The National Institute of Health and Care Excellence (NICE) break constipation in adults into two categories - chronic constipation of unknown cause and constipation due to opiates.In chronic constipation of unknown cause, the main treatment involves the increased intake of water and fiber (either dietary or as supplements). The routine use of laxatives or enemas is discouraged, as having bowel movements may come to be dependent upon their use. Fiber supplements
Soluble fiber supplements such as psyllium are generally considered first-line treatment for chronic constipation, compared to insoluble fibers such as wheat bran. Side effects of fiber supplements include bloating, flatulence, diarrhea, and possible malabsorption of iron, calcium, and some medications. However, patients with opiate-induced constipation will likely not benefit from fiber supplements. Laxatives
If laxatives are used, milk of magnesia or polyethylene glycol are recommended as first-line agents due to their low cost and safety. Stimulants should only be used if this is not effective. In cases of chronic constipation, polyethylene glycol appears superior to lactulose. Prokinetics may be used to improve gastrointestinal motility. A number of new agents have shown positive outcomes in chronic constipation; these include prucalopride and lubiprostone. Cisapride is widely available in third world countries, but has been withdrawn in most of the west.
Low fiber intake, inadequate amounts of fluids, poor ambulation or immobility, or medications can contribute to constipation. Once the presence of constipation is identified based on a culmination of the symptoms described above, then the cause of constipation should be figured out. Separating non-life-threatening from serious causes may be partly based on symptoms. For example, colon cancer may be suspected if a person has a family history of colon cancer, fever, weight loss, and rectal bleeding. Other alarming signs and symptoms include family or personal history of inflammatory bowel disease, age of onset over 50, change in stool caliber, nausea, vomiting, and neurological symptoms like weakness, numbness and difficulty urinating. Examination
A physical examination should involve at least an abdominal exam and rectal exam. Abdominal exam may reveal an abdominal mass if there is significant stool burden and may reveal abdominal discomfort. Rectal examination gives an impression of the anal sphincter tone and whether the lower rectum contains any feces or not. Rectal examination also gives information on the consistency of the stool, the presence of hemorrhoids, blood and whether any perineal irregularities are present including skin tags, fissures, anal warts. Physical examination is done manually by a physician and is used to guide which diagnostic tests to order. Diagnostic tests
Functional constipation is common and does not warrant diagnostic testing. Imaging and laboratory tests are typically recommended for those with alarm signs or symptoms.The laboratory tests performed depends on the suspected underlying cause of the constipation.
