O22: Venous complications and haemorrhoids in pregnancy

The group of conditions known as venous complications and haemorrhoids in pregnancy can occur when there are issues with the blood vessels, specifically the veins, during pregnancy. These complications arise due to the increased blood volume and hormonal changes during pregnancy, which can lead to the swelling of veins in the legs (varicose veins) and rectum (haemorrhoids). Common symptoms include discomfort, itching or pain in the affected area; in the case of haemorrhoids, there may also be bleeding during bowel movements. If left untreated, these conditions can progress, resulting in prolonged discomfort, blood clots, or ulceration. It's also important to note that these venous complications are linked to the circulatory and digestive systems.
