3. Fluid Retention (Edema)

Edema occurs when excess fluid builds up in body tissues. In seniors, this is often linked to conditions such as heart disease, kidney problems, or liver disorders. When these organs do not function properly, the body cannot regulate fluid balance, resulting in visible swelling.

4. Medication Side Effects

Many seniors take medications for chronic conditions. Some drugs, including blood pressure medications and anti-inflammatory treatments, may cause swelling as a side effect. If swelling appears after starting a new medication, medical advice should be sought.
