Why do haemorrhoids cause constipation?

Constipation is a common presentation of Haemorrhoids. Hard stool and pushing can increase pressure in the anal area and aggravate swollen tissue. In turn, fear of pain or bleeding may lead a person to postpone using the toilet. Haemorrhoids and constipation can therefore reinforce each other, but constipation also has many other possible causes, including diet, fluid intake, activity, medicines, and bowel conditions.

Build a routine that reduces straining: respond to the urge to open your bowels, allow unhurried toilet time, drink fluids through the day, and add fibre gradually through food. Gentle movement can support regular bowel activity. A pharmacist or clinician can help you choose a fibre product or stool-softening option if self-care is not enough. Avoid using strong laxatives repeatedly without advice.

Book a medical review if constipation is new or persistent, bowel habits have changed, or you see blood in the stool. Seek urgent care for severe abdominal pain, repeated vomiting, a swollen abdomen, inability to pass stool or gas, faintness, or black stool. These symptoms need evaluation and should not be attributed to haemorrhoids alone.

Ask whether your symptoms fit haemorrhoids, whether any medicines may be slowing your bowels, and how to increase fibre without worsening bloating. Tell them how often you pass stool, its consistency, whether you strain, and whether pain or bleeding makes you avoid the toilet.
