Hi Daya, Welcome to HealthcareMagic Forum.
You haven't said if your Husband is on any medications and what is his age? Because there are many causes for constipation
like Diabetes Mellitus
, few medicines like anti depressants, magnesium deficiency
, poor diet which is devoid of fiber, not taking enough fluids including water, intestinal gas, bowel obstruction and others. He needs a thourough evaluation by a Gastroenterologist at the earliest and if necessary a Colonoscopy
will always be fine to rule out if there is any problem with his Large Intestine like bowel obstruction. Do not give him further laxatives and fix an appointment with a Gatroenterologist. Let him take plenty of fiber rich foods and drink plenty of water. Ask him to exercise regularly this will increase his bowel movements.
