What causes facial swelling in elderly people?

In general, facial swelling in elderly individuals may be caused by fluid retention, improper sleeping posture, medication side effects, malnutrition, nephritis, or other conditions. If discomfort occurs, it is advisable to seek medical attention promptly. The specific causes are analyzed as follows:

1. Fluid Retention

Due to a decreased metabolic rate, elderly individuals may experience weakened kidney function, making it difficult for the body to eliminate excess fluid efficiently. This retained fluid can accumulate in the loose tissues of the face, leading to edema. It is recommended to limit salt intake, maintain appropriate fluid consumption, avoid drinking large amounts of water before bedtime, and engage in moderate physical activity to promote sweating and urination.

2. Improper Sleeping Posture

Elderly individuals may sleep with their heads positioned too low due to stiffness or habitual postures, which can impede facial blood return and result in facial swelling. Using an appropriate pillow to maintain a suitable head elevation and avoiding prolonged periods in the same sleeping position can help prevent this issue.

3. Medication Side Effects

Long-term use of certain medications, such as calcium channel blockers or nonsteroidal anti-inflammatory drugs (NSAIDs), can disrupt the body's sodium and water metabolism, potentially causing facial edema. Consult a physician to adjust dosages or switch to alternative medications if necessary.

4. Malnutrition

Weakened digestive and absorptive functions in older adults, along with inadequate nutrient intake, can lead to malnutrition. This reduces plasma osmotic pressure and increases interstitial fluid, resulting in facial swelling. A balanced diet rich in protein and vitamins, combined with smaller, more frequent meals, is recommended.

5. Nephritis

Kidney inflammation (nephritis) can be triggered by infections or reduced immune function, leading to a decreased glomerular filtration rate and subsequent retention of water and sodium in the body, which may manifest as facial swelling. Additional symptoms may include hypertension, hematuria, proteinuria, and reduced urine output. Under medical guidance, patients may be treated with medications such as prednisone acetate tablets, Jinshuibao capsules, or alprostadil injection.

Elderly individuals should maintain healthy lifestyle habits, follow a balanced diet, engage in moderate exercise, undergo regular health check-ups, and adjust their lifestyles and medication regimens as needed to prevent the occurrence of facial swelling and other forms of edema.
