The text explains the causes and symptoms of chronic venous insufficiency (chronic venous hypertension), a condition where the veins weaken over time, making it harder for blood to flow back to the heart. The risk factors include: * Age: Veins deteriorate with age, especially in women starting in their 40s * Gender: Women are more likely to suffer from venous diseases than men, due to weight distribution and pregnancy * Body weight: Extra weight puts pressure on organs, muscles, and blood vessels, increasing the risk of chronic venous hypertension * Occupation and lifestyle: Jobs that require standing for long periods or a sedentary lifestyle without regular exercise can weaken veins Symptoms include: * Pain in the legs * Leg cramping * Skin discoloration * Lower leg and ankle ulcers * Varicose veins (although these are just one of many possible symptoms) The text also mentions that Dr. Banda, an expert in treating vein conditions, diagnoses and treats chronic venous hypertension and other vein conditions to help the body stay healthy. Treatment options include compression socks or garments, elevating legs while lying down, avoiding prolonged periods of sitting or standing, and following a regular exercise routine like walking or running. Overall, the text aims to educate readers about the causes, symptoms, and treatment options for chronic venous insufficiency, with the goal of promoting vein health and preventing more serious conditions.
