Why do elderly people have swollen feet?

Swollen feet in the elderly may be a problem that many people experience. Swollen feet, in simple terms, is the phenomenon of swelling in the feet due to fluid retention. For the elderly, this condition can be caused by a variety of reasons, including but not limited to heart, kidney or liver dysfunction, varicose veins, and even side effects of some medications. Understanding these potential causes can help us better cope with and manage this condition.

Heart problems are one of the common causes of swollen feet in the elderly. A weak heart can cause poor blood circulation, which can lead to a buildup of fluid in the lower extremities. In this case, swollen feet are often accompanied by other symptoms, such as shortness of breath or fatigue. If an elderly person experiences these symptoms, it is very important to seek medical attention immediately.

Decreased kidney function is also a major cause of swollen feet in the elderly. The kidneys are responsible for removing excess fluid and waste from the body, and if kidney function weakens, fluid in the body may begin to accumulate in the feet. Liver disease may also cause fluid retention, as the liver plays an important role in protein synthesis and fluid regulation.

Of course, lifestyle and eating habits can also affect the degree of edema. Standing or sitting for long periods of time, consuming too much sodium, and lack of exercise can all worsen edema. For older people, proper exercise and a healthy diet are key to staying healthy. Eating more potassium-rich foods, such as bananas and spinach, can help balance the sodium and potassium levels in the body, thereby reducing edema.

If you find that your feet are swollen or getting worse, it is recommended that you consult a doctor for a detailed examination. Through professional medical evaluation, the specific cause can be determined, and the most effective treatment measures can be taken. Although swollen feet are common, the reasons behind them may be complex. Timely attention and treatment are the key to staying healthy. I hope this information can help you better understand and manage the problem of swollen feet in the elderly.
