Many women suffer from fluid retention, especially on hotter days. This happens when excess fluid builds up in the body. It is also known as edema and occurs in the circulatory system or within tissues and cavities. It can cause swelling in the hands, feet, ankles, and legs.
Fluid retention is an increasingly common problem. Swollen legs at the end of the day, with pressure marks from socks or shoes, are an example of edema or fluid retention. The problem is caused by abnormal accumulation of fluid within the body's tissues, and is most common in women during menstruation or pregnancy.
