"There are many different causes of chronic constipation. It can be due to structural lesions of the colon (e.g., colon cancer, colon stricture or narrowing), medical conditions such as diabetes, thyroid disorders, Parkinson’s disease, or pregnancy, or due to medications such as pain medications (narcotics), blood pressure medications (calcium channel blockers), anti-seizure medication, and antispasmodics. In these cases, switching to a new medication can improve the symptoms. In people over 50, a more serious bowel disease or a structural disorder could cause the onset of constipation, so it is important to see a health professional to rule out any serious causes.
Chronic constipation that is not due to “secondary” causes, such as other medical conditions or medications, is referred to as “functional constipation.” The three main causes of functional constipation are normal transit constipation, slow transit constipation, and defecatory or evacuation disorders. In normal-transit constipation, the rate of stool passage through the colon and stool frequency are normal, but patients perceive that they are constipated. Changes in the water content of the colon may also play a role in this type of constipation. In slow-transit constipation, passage of stool through the colon is slower than normal. Defectory disorders that can cause constipation include dyssynergic defecation, rectal prolapse (protrusion of rectal tissue through the anal opening), and rectocele (outpouching of the rectum). In dyssynergic dysfunction, also referred to as pelvic floor dysfunction or anismus, there is ineffective coordination of the pelvic floor, abdominal, rectal, and anal sphincter musculature in the evacuation mechanism."
