What causes puffy eyes after sleeping?

Under normal circumstances, eye swelling after sleep may be caused by lack of sleep, excessive fluid intake before bedtime, conjunctivitis, blepharitis, glomerulonephritis, or other reasons. It is recommended to seek medical attention promptly, identify the underlying cause, and receive symptomatic treatment under a doctor's guidance. Specific analyses are as follows:

1. Lack of sleep: Staying up late at night can lead to insufficient sleep, preventing the eyes from fully resting and impairing local blood circulation, which may result in swelling. It is important to ensure adequate sleep, avoid staying up late, and refrain from using mobile phones before bedtime.

2. Excessive fluid intake before bedtime: Drinking large amounts of water before sleep increases fluid retention in the body, potentially causing eye edema. Avoid drinking large volumes of water before bed. Gentle eye massage, if recommended by a physician, may help reduce swelling.

3. Conjunctivitis: This condition may be related to infection or immune abnormalities. Inflammation can cause eye swelling, often accompanied by symptoms such as itching and increased eye discharge. Patients may use medications such as chloramphenicol eye drops, ganciclovir eye drops, or ofloxacin eye drops as directed by a physician.

4. Blepharitis: Most commonly caused by staphylococcal infection, it is characterized by redness, swelling, heat, and pain in the affected area. Eye swelling may be particularly noticeable upon waking. Patients should use medications such as levofloxacin hydrochloride eye drops, tobramycin eye drops, or erythromycin eye ointment as prescribed.

5. Glomerulonephritis: This may be associated with genetic factors, infections, or immune dysfunction. If left untreated, it can impair kidney function, leading to an inability to eliminate excess fluid from the body. This may result in facial and severe eyelid edema, along with symptoms such as hematuria (blood in urine) and proteinuria (protein in urine). Treatment under medical supervision may include medications such as furosemide injection, captopril tablets, or cyclosporine soft capsules.

In daily life, maintain proper eye hygiene, avoid overuse of the eyes, and limit prolonged screen time on mobile devices. Diet-wise, avoid spicy foods such as chili peppers and Sichuan pepper, and opt for light, non-irritating meals.
