People with chronic constipation caused by anorectal dysfunction can use biofeedback to retrain the muscles that control release of bowel movements intolerance-symptoms-of-lactose-intolerance Biofeedback involves using a sensor to monitor muscle activity that at the same time can be displayed on a computer screen, allowing for an accurate assessment of body functions intolerance-symptoms-of-lactose-intolerance functions intolerance-symptoms-of-lactose-intolerance A health care professional uses this information to help the patient learn how to use these muscles intolerance-symptoms-of-lactose-intolerance Physical Examination Problems with Intestinal Function (Chronic Idiopathic Constipation) problems with the colon and rectum Saline laxatives act like a sponge to draw water into the colon for easier passage of of stool intolerance-symptoms-of-lactose-intolerance Laxatives in this group include Milk of Magnesia and Haley's M-O intolerance-symptoms-of-lactose-intolerance scleroderma sensation of anorectal blockage/obstruction sensation of incomplete evacuation Several kinds of diseases can cause constipation: sigmoidoscopy or colonoscopy Sigmoidoscopy or colonoscopy intolerance-symptoms-of-lactose-intolerance An examination of the rectum and lower (sigmoid) colon is called a sigmoidoscopy intolerance-symptoms-of-lactose-intolerance sigmoidoscopy intolerance-symptoms-of-lactose-intolerance An examination of the rectum and entire colon is called a colonoscopy intolerance-symptoms-of-lactose-intolerance Some medications can cause constipation intolerance-symptoms-of-lactose-intolerance They include Some people have chronic constipation that does not respond to standard treatment intolerance-symptoms-of-lactose-intolerance This rare condition, known as idiopathic (of unknown origin) chronic constipation may be related to to problems with intestinal function such as problems with hormonal control or with nerves and muscles in the colon, rectum, or anus intolerance-symptoms-of-lactose-intolerance Functional constipation occurs in both children and adults and is most common in women intolerance-symptoms-of-lactose-intolerance Some people with IBS, also known as spastic colon, have spasms in the the colon that affect bowel movements intolerance-symptoms-of-lactose-intolerance Constipation and diarrhea often alternate, and abdominal cramping, gassiness, and bloating are other common complaints intolerance-symptoms-of-lactose-intolerance Although IBS can produce lifelong symptoms, it is not a life-threatening condition intolerance-symptoms-of-lactose-intolerance It often worsens with stress, but there is no specific cause or anything unusual that that the doctor can see in the colon intolerance-symptoms-of-lactose-intolerance Sometimes constipation can lead to complications intolerance-symptoms-of-lactose-intolerance These complications include hemorrhoids caused by straining to have a bowel movement or anal fissures (tears in the skin around the anus) caused when hard stool stretches the sphincter muscle intolerance-symptoms-of-lactose-intolerance As a result, rectal rectal bleeding may occur, appearing as bright red streaks on the surface of the stool intolerance-symptoms-of-lactose-intolerance Treatment for hemorrhoids may include warm tub baths, ice packs, and application of a special cream to the affected area intolerance-symptoms-of-lactose-intolerance Treatment for anal fissure may include stretching the sphincter muscle or surgical removal of of tissue or skin in the affected area intolerance-symptoms-of-lactose-intolerance Sometimes straining causes a small amount of intestinal lining to push out from the anal opening intolerance-symptoms-of-lactose-intolerance This condition, known as rectal prolapse, may lead to secretion of mucus from the anus intolerance-symptoms-of-lactose-intolerance Usually eliminating the cause of the prolapse, such as as straining or coughing, is the only treatment necessary intolerance-symptoms-of-lactose-intolerance Severe or chronic prolapse requires surgery to strengthen and tighten the anal sphincter muscle or to repair the prolapsed lining intolerance-symptoms-of-lactose-intolerance Specific Diseases specific diseases such as stroke (by far the most common) spinal cord injuries Stimulants cause rhythmic muscle contractions contractions in the intestines intolerance-symptoms-of-lactose-intolerance Brand names include Correctol, Dulcolax, Purge, and Senokot intolerance-symptoms-of-lactose-intolerance Studies suggest that phenolphthalein, an ingredient in some stimulant laxatives, might increase a person's risk for cancer intolerance-symptoms-of-lactose-intolerance The Food and Drug Administration has proposed a ban on all over-the-counter products containing phenolphthalein intolerance-symptoms-of-lactose-intolerance Most laxative makers |
