Constipation

Symptoms

Constipation usually results from not getting enough exercise, not drinking enough water, or from a diet that does not include an adequate amount of fiber-rich foods like beans, bran cereals, fruits, raw vegetables, rice, and whole-grain breads.

Other causes of constipation include anal fissure (a tear or crack in the lining of the anus); chronic kidney failure; colon or rectal cancer; depression; hypercalcemia (abnormally high levels of calcium in the blood); hypothyroidism (underactive thyroid gland); illness requiring complete bed rest; irritable bowel syndrome; and stress.

Constipation can also be a side effect of:

• aluminum salts in antacids
• antihistamines
• antipsychotic drugs
• aspirin
• belladonna (Atopa belladonna, source of atropine, a medication used to relieve spasms and dilate the pupils of the eye)
• beta blockers (medications used to stabilize irregular heartbeat, lower high blood pressure, reduce chest pain)
• blood pressure medications
• calcium channel blockers (medication prescribed to treat high blood pressure, chest pain, some types of irregular heartbeat and stroke, and some non-cardiac diseases)
• diuretics (drugs that promote the formation and secretion of urine)
• iron or calcium supplements
• narcotics (potentially addictive drugs that relieve pain and cause mood changes)
• tricyclic antidepressants (medications prescribed to treat chronic pain, depression, headaches, and other illnesses)

An adult who is constipated may feel bloated, have a headache, swollen abdomen, or pass rock-like feces; or strain, bleed, or feel pain during bowel movements. A constipated baby may strain, cry, draw the legs toward the abdomen, or arch the back when having a bowel movement.
