Having infrequent or difficult-to-pass bowel motions is known as constipation. Common causes include lack of exercise, eating less fibre, or not drinking enough fluids. Opioid medicines, some anti-nausea medicines and some chemotherapy drugs also cause constipation.
Severe constipation plus abdominal pain, bloating, nausea and vomiting may be signs of a blockage in the bowel (bowel obstruction). This occasionally happens with peritoneal mesothelioma. To relieve the symptoms, you may have a small tube (stent) put in to help keep the bowel open. If the bowel is completely blocked, it needs to be cleared with emergency surgery.
Managing constipation
- Drink plenty of fluids.
- Eat fresh fruit and vegetables and fibre-rich foods (e.g. prunes), unless your doctor advises otherwise.
- Try to be physically active every day. Talk to your doctor or physiotherapist to find the exercise that is right for you.
- Ask your doctor how to manage constipation. You may be prescribed medicines to help control symptoms.
- Try over-the-counter laxatives such as Coloxyl with senna, Duphalac or Movicol, but check the dose with the pharmacist and let your doctor know. Don’t wait too long before starting laxatives.
- Talk to your treatment team about how to manage bowel obstruction. If your stomach is swollen and you are in pain, call 000 as it may be an emergency.
