After overnight journey in sitting position without moving lower part of leg swollen this is called Edina.how it is caused

Answer 1

Edema is swelling that is caused by fluid trapped in your body’s tissues. Edema happens most often in the feet, ankles, and legs, but can affect other parts of the body, such as the face, hands, and abdomen. It can also involve the entire body.

• Edema can occur as a result of gravity, especially from sitting or standing in one place for too long. Water naturally gets pulled down into your legs and feet.
• It can happen from a weakening in the valves of the veins in the legs (a condition called venous insufficiency). This problem makes it hard for the veins to push blood back up to the heart, and leads to varicose vein and a buildup of fluid in the legs.
• Certain diseases — such as congestive heart failure and lung, liver,kidney, and thyroid disease — can cause edema or make it worse.
• Some drugs, such as medications that you are taking for your blood pressure or to control pain, may cause or worsen edema.
• An allergic reaction, severe inflammation, burns, trauma, clot(s), or poor nutrition can also cause edema.
• Too much salt from your diet can make edema worse.
• Being pregnant can cause edema in the legs as the uterus puts pressure on the blood vessels in the lower trunk of the body.
