Dr. Donald J. Fleischli: This 47-year-old woman entered the hospital complaining of intermittent cramps and diarrhea during the past year. A typical attack lasted three to four days and consisted of five to ten episodes of severe lower-abdominal cramps and urgency, relieved promptly by defecation, which often produced only small amounts of loose watery stool containing mucus but no blood.
