Suddenly swollen eyelids may be a physiological phenomenon, or it may be caused by various factors such as inflammatory reaction, allergic reaction, systemic edema, systemic malnutrition and trauma, which can be analyzed in two categories: physiological factors and pathological factors. I. Physiological factors 1. Poor sleep: Because of staying up late or poor sleep environment, resulting in too little sleep time or poor sleep quality, you will find your eyelids suddenly swollen when you wake up in the morning. It is recommended not to stay up late, or try to sleep in a quiet, warm environment, you can also wet compress the eyes with a warm towel to promote blood circulation around the eyes and reduce the eyelid swelling; 2, poor sleeping posture: sleep at night with a pillow that is too low, resulting in the sudden edema found on the eyelids when you wake up in the morning. This situation can be avoided by replacing the pillow, reducing the large amount of water before bed, and improving the bad sleeping posture to avoid the eyelids swelling again. Second, pathological factors 1, inflammatory reactions: factors leading to swollen eyelids may be caused by bacterial infections, common conjunctivitis, wheals, chalazion, etc. When inflammation constantly stimulates the eyes, there will be eyelid swelling and pain and other reactions; 2, allergic reactions: eyelids suddenly swollen may be the eyes contact with pollen, dust and other allergens caused by allergic conjunctivitis, when allergic conjunctivitis occurs, the eyes will hypersensitivity reaction, the eyelids will suddenly become swollen, there will also be red eyes, increased secretions, etc., or because of mosquito bites caused by allergic reactions to the eyelids; 3, systemic edema: because of renal edema, hepatic edema and cardiogenic edema can lead to eyelid edema; renal edema is mainly due to a decrease in the filtration capacity of the glomerulus, the renal tubular reabsorption slowed down due to systemic edema, common eyelids and the entire Hepatic edema is mainly due to impaired liver function, causing obstruction of portal venous reflux, resulting in venous blood stasis leading to eyelid edema, as well as a decline in liver function, resulting in low plasma albumin and other causes of systemic edema; while cardiogenic edema is mainly due to the occurrence of right heart failure, venous reflux is obstructed, commonly lower limb edema, which can seriously cause sudden edema of the eyelid; 4, systemic malnutrition: malnutrition is mainly It is because the level of albumin in plasma decreases, causing a decrease in plasma osmotic pressure, causing an increase in intertissue fluid, which can lead to edema of the eyelids, face and limbs, and in more serious cases, also secondary to ascites; 5, trauma: external injury can lead to edema bruising of the eyelids of patients, which is manifested as a sudden swelling of the eyelids, and patients are advised to go to the hospital for trauma treatment as soon as possible to avoid delaying the disease, affecting vision and leading to irreversible damage. When the eyelid swelling occurs, you need to ensure sufficient sleep in ordinary life and develop good habits of rest and relaxation, you can also carry out appropriate ice packs to eliminate edema or massage the eyes to promote blood circulation; for inflammation-induced eye swelling can apply some anti-inflammatory ointment for application to relieve symptoms, in addition to avoid contact with allergens that cause eye swelling, for edema caused by systemic factors, you need to consult a doctor for systematic professional For edema caused by systemic factors, systematic and professional treatment is needed.
