discuss varicose veins
Varicose veins are when the veins in the lower limbs become enlarged and swollen because the valves in the veins are weak. The cause of weak valves in the veins are increased blood pressure in the legs, overweight, or venous insufficiency. Treatment for this is to not stand for long periods of time or to elevate the feet and rest. Some side effects include fatigue, tiredness, or pain.
Atherosclerosis is when plaque builds up in the arteries and hardens. This makes the heart work harder to pump blood. This can be caused by poor diet, lack of exercise, or being overweight. This increases blood pressure and can cause hypertension. Blockages may occur and can cause heart attack or stroke. This can be prevented by dieting, exercise, or medication. This can be treated by surgically removing the plaque from the artery or replacing the artery.
