Water retention, also known as fluid retention or edema, occurs when the body holds onto excess fluid. This can happen for various reasons, including a high-salt diet, hormonal changes, or certain medical conditions. The retained fluid can lead to swelling, particularly in the legs, ankles, and feet. In some cases, water retention may be temporary and resolve on its own. However, if it persists or is accompanied by other symptoms, it is important to consult a healthcare professional. They can help determine the underlying cause and recommend appropriate treatments or lifestyle changes to manage the condition.
