The most cause of swollen feet and legs is caused by increased fluid buildup when one sits or stands for long periods of time without switching positions. Serious health conditions can also cause swelling, such as deep vein thrombosis, lymphedema, cellulitis, and heart failure. Eating foods that are high in sodium and not drinking enough water can also lead to swelling and bloating all over the body.
Sitting at a desk while working all day or standing in one spot without moving are both common causes of swollen feet and legs. This can usually be easily remedied by moving around during the day and getting adequate exercise. Drinking plenty of water and staying away from foods that can cause bloat, such as excess salt, may also help reduce swelling.
Being overweight or pregnant can also cause swelling in the feet and legs. In pregnancy, this is partially due to the extra blood flow in the body. The extra weight around the middle in both instances can also hinder the drainage of fluids from the body and lead to swelling. Treatment for this are generally the same as for swelling being caused by lack of movement. Losing weight may also help.
Sometimes a serious health condition will be to blame for swollen feet and legs. Cellulitis is a condition caused by a skin infection which can cause swelling. Additional symptoms are usually also present and can include redness, pain, soreness, fever, and warmth in the affected area. Treatment generally involves antibiotics.
Congestive heart failure can also cause swollen feet and legs, as well as swelling in the abdomen. It can be caused by too many fluids being retained in the body and the chest. As the heart pumps blood less efficiently, even more fluids are retained and the condition worsens. Medication and sometimes surgery is often necessary.
Varicose veins and deep vein thrombosis are both conditions which can lead to swelling in the legs and feet. Varicose veins are generally swollen and filled with blood while deep vein thrombosis refers to a blood clot in the veins. These conditions are related because varicose veins are more susceptible to clotting than normal.
