What causes a child's fever and swollen eyes?

Generally speaking, fever refers to an elevated body temperature. Possible causes of eye swelling in children with fever may include fluid accumulation, allergic reactions, conjunctivitis, glomerulonephritis, and Kawasaki disease. If any discomfort occurs, it is recommended to seek timely medical attention and receive targeted treatment under a doctor's guidance. A detailed explanation is as follows:

1. Fluid Accumulation

When a child has a fever, the body's metabolism speeds up and blood circulation accelerates, which may cause fluid to accumulate in the tissues around the eyes, leading to eye swelling. Additionally, during fever, children may drink less water, although their body's demand for water does not decrease, which may also cause local edema. Ensure adequate hydration during fever, while avoiding excessive water intake to prevent water intoxication. Arrange sufficient rest and avoid strenuous exercise to reduce the risk of excessive fluid accumulation.

2. Allergic Reaction

During fever, children may develop allergic reactions to certain medications or foods, causing congestion and swelling of the eye tissues. Understand the child's allergens and try to avoid exposure. Before administering medication, carefully read the drug instructions to understand the ingredients, and consult a doctor for skin testing if necessary.

3. Conjunctivitis

Conjunctivitis may be caused by bacterial or viral infection. Inflammation leads to conjunctival congestion and swelling, often accompanied by a foreign body sensation in the eye, tearing, and increased secretions. Symptoms may also include photophobia and blurred vision. Under a doctor's guidance, medications such as levofloxacin eye drops, acyclovir eye drops, and epinastine fumarate eye drops may be used for treatment.

4. Glomerulonephritis

Glomerulonephritis may be caused by streptococcal infection. Kidney function impairment leads to water and sodium retention, causing edema in the periorbital tissues. Other symptoms may include proteinuria, hypertension, and reduced urine output. Treatment should follow medical advice to use medications such as furosemide tablets, penicillin V potassium tablets, and compound cyclophosphamide tablets.

5. Kawasaki Disease

Kawasaki disease may be related to infection and immune abnormalities. Vasculitis leads to ocular blood vessel congestion and swelling. Symptoms may include rash, lymphadenopathy, and hard edema of the hands and feet. Under a doctor's recommendation, medications such as aspirin enteric-coated tablets, intravenous immunoglobulin, and prednisone tablets may be used for treatment.

In daily life, children should be taught to wash hands frequently, avoid rubbing their eyes, and reduce the risk of eye infections. Maintain a balanced diet, ensure adequate nutrition, and engage in regular exercise to enhance immunity.
