medical management of IBS
Restriction and then gradual reintroduction of foods that are possible irritating may help determine what types of food are acting as irritants
changes for IBS patients
o High fiber diet, exercise, stress reduction or behavioral modification therapy programs
may be prescribed to decrease smooth muscle spasms decrease cramping & constipation for IBS patients
o Anticholinergics or antispasmodics (propantheline)
