What causes thrombosed haemorrhoids?
Haemorrhoids are delicate ‘cushions’ around the bottom that are filled with blood vessels designed to help control our bowel movements and make stools easier to pass. When there is too much pressure on them they can become swollen. Sometimes blood clots can form in these swollen areas but it is not always clear why this happens. Some of the most common causes of haemorrhoids include:
▶Straining too hard when going to the toilet
▶Constipation - difficulty passing a stool can result in excessive straining
▶Diarrhoea - frequent toilet trips and pushing can put extra pressure on the bottom
▶Spending a long time on the toilet (e.g. due to constipation or diarrhoea)
▶A low fibre diet – fibre foods help to make stools soft and easier to pass
▶Heavy lifting – lifting heavy weights, for example at the gym, can also exert too much pressure on the blood vessels around the bottom
▶Obesity – being overweight can put extra strain on your body
▶Pregnancy – hormonal changes can relax the blood vessels and the weight of an enlarged uterus can put pressure on haemorrhoids
▶Older age – as we get older the tissues holding haemorrhoids in place can weaken.
