1. Constipation

Constipation is when a person is not having bowel movements as often as is normal for them, or if they are having difficulty passing stools, which may be dry and lumpy. There may also be associated nausea and/or stomach ache. Constipation can be caused by not eating enough fibre or drinking enough fluids, as well as by certain medicines, changes to the usual diet, lack of exercise or stress.

2. Diarrhoea

Diarrhoea is the passing of frequent watery stools. There may be other symptoms too, such as stomach cramps, loss of appetite, dehydration or a fever. The causes of diarrhoea include infection, food intolerances and allergies, as well as certain medicines.

3. Haemorrhoids

Haemorrhoids, or piles as they are more commonly known, are associated with increased pressure on the blood vessels in the rectum and anus, and can be either internal or external. It is not fully understood why piles occur, but straining to go to the toilet, pregnancy, being overweight or lifting heavy objects are all contributory factors. Symptoms include bleeding after a bowel movement (the blood is bright red), itching, and protruding lumps and soreness in and around the area.
