Q82.0: Hereditary lymphoedema

Hereditary lymphedema is a genetic condition that involves swelling (edema) due to an impaired lymphatic system, which plays a crucial role in your immune function and fluid balance. In people with this condition, the body has trouble clearing away waste materials and immune cells from tissues, leading to localized or widespread swelling, most often in the arms or legs. Symptoms usually become apparent at birth or during puberty when hormonal changes can trigger the onset. The primary indication is noticeable swelling, which can impact daily activities and quality of life. As a hereditary condition, it is passed on within families, typically through an abnormal gene you receive from one or both parents. The disease progression varies, meaning some individuals will have mild swelling and others will have a more extreme presentation. Regardless of the severity, it is a chronic condition and requires lifelong management.
