What causes the body to swell easily?

Generally, body swelling may be caused by physiological reasons, but it could also be due to medical conditions such as hypothyroidism or nephrotic syndrome. The specific analysis is as follows:

I. Physiological Factors

Excessive fluid intake before sleep, especially without urination during the night, can lead to fluid retention in the body, resulting in easy swelling, typically presenting as facial and hand edema. If no other discomfort symptoms are present, no special treatment is required—simply avoiding drinking fluids before bedtime is sufficient.

II. Pathological Factors

1. Hypothyroidism

Insufficient secretion of thyroid hormones in the body leads to deposition of mucoproteins, triggering myxedema. Treatment may include oral administration of thyroid hormone tablets or levothyroxine sodium tablets, as directed by a physician.

2. Nephrotic Syndrome

Due to abnormal kidney function, the kidneys cannot properly metabolize and eliminate fluid from the body, leading to fluid retention, proteinuria, and elevated blood pressure. Medications such as furosemide tablets or spironolactone tablets may be prescribed for treatment.

In addition to the above causes, heart failure, liver cirrhosis, and heart disease cannot be ruled out. However, the exact cause should be evaluated through medical examination at a local hospital, followed by targeted treatment based on the diagnosed condition.
