Haemorrhoids
1
Haemorrhoids are swollen and inflamed varicose veins located on the rectum or anus.
Straining with bowel movements causes pressure on the blood vessels of the anus and rectum, and if the blood vessels are weak, the increased pressure can cause them to swell and become distorted, leading to the formation of haemorrhoids.
Other sources of pressure in the anal region may include pregnancy, standing and sitting for long periods, heavy lifting, liver disease, coughing, sneezing, and vomiting. Sitting on hard surfaces for extended periods of time may also contribute.
A hereditary component may also play a role in the development of haemorrhoids.
Bleeding from the bowel always requires further medical investigation to determine the cause - consult your healthcare professional for more information.
