Hemorrhoids Causes
Hemorrhoids CausesAuthor: bcured Hemorrhoids are a common health condition worldwide. Although many patients and clinicians believe that hemorrhoids are caused by chronic constipation, prolonged sitting, and vigorous straining, little evidence to support a causative link exists. Other risk factors historically associated with the development of hemorrhoids include the following: pregnancy, lack of erect posture, familial tendency, higher socioeconomic status, chronic diarrhea, colon malignancy, hepatic disease, obesity, elevated anal resting pressure, spinal cord injury, loss of rectal muscle tone, rectal surgery, episiotomy, anal intercourse, and so on. Varicosities caused from portal hypertension are a distinct entity from hemorrhoids. A CBC may be useful as a marker for infection. Anemia due to hemorrhoidal bleeding is possible, albeit rare (0.5 cases per 100,000 patients), and its presence should raise suspicion of an alternate diagnosis. Proctogram may be indicated in rectal prolapse. Proctoscopy may be performed to supplement anoscopy. Full evaluation of the large bowel with colonoscopy is recommended for patients with significant abdominal symptoms, weight loss, change in bowel habits, age older than 50 years, or other risk factors for colonic malignancy. Most hemorrhoids resolve spontaneously or with conservative medical therapy alone. Along with over-the-counter topical agents, there are several modalities at the disposal of physicians to treat piles.
