Also known as piles, haemorrhoids are best described as swellings found inside or around the bottom – the rectum and anus – which contain enlarged blood vessels. The cause of them is often associated with an increased blood pressure of the blood vessels in the anus, causing those in the back passage to become swollen and inflamed.
Many things have been linked to causing the increased blood pressure in the anus that results in piles. This includes too much straining from experiencing constipation, caused by a lack of fibre. Other factors include being overweight or pregnant, long-term diarrhoea, regularly lifting heavy objects and sitting down for long periods of time.
There are different symptoms that are associated with haemorrhoids. These include and an itchy bottom and bleeding after passing a stool, which is usually bright red blood. Others include a lump hanging down outside the anus, mucus discharge after passing a stool, as well as soreness, swelling and redness around the bottom.
