You can retain up to 2.5 kg of fluid per day. Here’s how to get rid of the excess.

Why Your Body Retains Fluid

Fluid retention (also called edema in more noticeable cases) happens when excess water builds up in the body’s tissues instead of being properly eliminated.

Common causes include:

• High salt (sodium) intake
• Hormonal changes (especially in women)
• Prolonged sitting or standing
• Hot weather
• Certain medications
• Low physical activity

Most everyday fluid retention is temporary and harmless, but it can feel uncomfortable—causing bloating, puffiness, or swelling in the hands, feet, or face.
