Stools from a colostomy should remain soft. If they become hard (like rabbit pellets) you may need to increase your fluid intake. Contact your specialist nurse if it persists.
You cannot be constipated with an ileostomy but if the waste matter in your pouch seems too thick, drink extra fluids.
Do not forget that some drugs can change the output from your stoma. Antibiotics, indigestion medicines, iron tablets and laxatives, may give you a looser bowel action. Conversely, iron tablets and painkillers, especially those with codeine, may cause constipation. Anti-depression medicines may also affect your bowels. Do remember that some medicines may change the colour of your motions and in some instances your urine. Check with your pharmacist or specialist nurse.
