👉 Altered veins are typically characterized by visible changes in their appearance, such as being more prominent, dilated, or discolored. These changes can be caused by various factors, including genetics, aging, or underlying medical conditions like varicose veins or blood clots. In some cases, altered veins may also be a symptom of more serious health issues, such as lymphedema or cancer. Treatment options for altered veins depend on the underlying cause and severity of the condition.
