The diagnosis is made by examining the anus and anal canal, and it is important to exclude more serious causes of bleeding, such as cancer. No relation between piles and cancer has been found. A simple look inside is done by a procedure called proctoscopy where a 3 inch long hollow instrument with a diameter of about 1 inch is introduced in the rectum and with the help of a torch, the inside is looked at by the doctor. The procedure is painless and is done in the OPD.
Occasionally sigmoidoscopy and colonoscopic examination of the large intestine may be required if other diseases are suspected. these procedure are done under sedation or anaesthesia.
PREVENTION OF PILES
The best way to prevent haemorrhoids is to keep stools soft so they pass easily, thus decreasing pressure and straining, and to empty bowels as soon as possible after the urge occurs. Increased fibre in the diet helps reduce constipation and straining by producing stools that are softer and easier to pass. If the diet cannot be modified in this way, adding bulk laxatives may be necessary; they can prevent worsening of the condition. There are numerous creams and suppositories that can relieve anal irritation and pain, but they rarely provide long term benefit.
In addition, a person should not sit on the toilet for a long period of time.
