How should an 80-year-old elderly person reduce foot swelling?

Generally, foot swelling in the elderly is commonly caused by physiological edema, prolonged sitting or standing, hypothyroidism, deep vein thrombosis, diabetes, and other factors. Swelling can be reduced through general management and medication. If discomfort occurs, timely medical consultation is recommended. Specific causes are analyzed as follows:

1. Physiological Edema

Some elderly individuals may develop physiological edema in the evening or after prolonged walking, manifesting as foot swelling. Regular moderate exercise, adequate rest, and avoiding extended periods of walking are recommended.

2. Prolonged Sitting or Standing

Reduced physical activity in the elderly, along with long periods of sitting or standing, can slow venous blood return in the lower limbs, leading to blood pooling and foot swelling. It is important to avoid maintaining the same posture for extended durations.

3. Hypothyroidism

Long-term insufficient iodine intake can lead to hypothyroidism, disrupting metabolism and fluid balance, resulting in non-pitting edema in the lower limbs. This may be accompanied by symptoms such as cold intolerance and excessive sleepiness. Elderly individuals can increase iodine intake by consuming seaweed and should, under medical guidance, take medications such as methylprednisolone tablets, propranolol hydrochloride tablets, and levothyroxine sodium tablets.

4. Deep Vein Thrombosis

In the elderly, decreased vascular elasticity and slowed blood flow may lead to deep vein thrombosis in the lower limbs. The clot causes blood and tissue fluid to leak into the interstitial spaces, resulting in foot swelling, possibly accompanied by pain and fever. Elevating the affected limb and wearing compression stockings can help promote venous return and reduce swelling. Under medical supervision, medications such as rivaroxaban tablets, warfarin sodium tablets, and diosmin tablets may also be used.

5. Diabetes

Diabetes, often associated with obesity and irregular lifestyle, can damage capillary wall integrity and increase vascular permeability, leading to increased tissue fluid accumulation and foot swelling. Symptoms may include increased thirst and appetite. Under medical guidance, medications such as metformin hydrochloride tablets, glipizide tablets, and glimepiride tablets may be prescribed for treatment.

Elderly individuals should maintain moderate physical activity, avoid prolonged sitting or standing, follow a balanced diet, limit alcohol consumption, and take preventive measures against foot swelling.
