What causes haemorrhoids?
“Weak” veins – leading to haemorrhoids and other varicose veins – may be inherited. It’s likely that extreme abdominal pressure causes the veins to swell and become susceptible to irritation. The pressure can be caused by obesity, pregnancy, standing or sitting for long periods, straining on the toilet, coughing, sneezing, vomiting, and holding your breath while straining to do physical labour. Diet has a pivotal role in causing – and preventing – haemorrhoids. People who consistently eat a high-fibre diet are less likely to get haemorrhoids, but those who prefer a diet high in processed foods can expect them. A low-fibre diet or inadequate fluid intake can cause constipation, which can contribute to haemorrhoids in two ways: it promotes straining on the toilet and it also aggravates the haemorrhoids by producing hard stools that further irritate the swollen veins.
