Answer

Bladder dysfunction was identified in 50% of patients with irritable bowel syndrome and in only 13% of control subjects. One study found patients with irritable bowel syndrome to have a higher incidence of orthostatic hypotension. A clinical study demonstrated a greater reduction of forced expiratory volumes in 1 second (FEV1) induced by methacholine in patients with irritable bowel syndrome than in control subjects.
