Edema is the medical word for swelling brought on by an accumulation of excess fluid in human tissues. It takes place when there is an imbalance between the flow of fluid out of the blood vessels and the clearance of fluid from the lymphatic or circulatory systems. This fluid accumulation leads to the damaged tissues expanding, which results in edema that is visible and makes the affected area feel heavy or tight. The legs, ankles, feet, hands, face, and abdomen are just a few of the body areas that edema can affect. Here you can find Symptoms and Causes of Edema in Pakistan at imchospital.
