Donald Trump recently received a diagnosis of Chronic Venous Insufficiency (CVI), sparking interest in this condition. CVI occurs when leg veins fail to effectively return blood to the heart due to damaged or weak valves. If left unaddressed, CVI can lead to swelling, pain, and other symptoms. Risk factors include deep vein thrombosis (DVT), varicose veins, long periods of sitting or standing, obesity, pregnancy, aging, gender, and injuries. Symptoms of CVI include leg pain, swelling, varicose veins, skin changes, and ulcers. Treatment often involves lifestyle changes, compression stockings, and medical interventions. By understanding the causes, symptoms, and treatments of CVI, individuals can better manage this condition and improve vein health.
