Early eyelid swelling may be related to nephritis, visual fatigue, improper sleeping position, drinking too much water before going to bed and other reasons. 1. Nephritis: the glomerular filtration rate of patients with nephritis is reduced, which will lead to drainage dysfunction and fluid accumulation in the body, and the eyelid skin is relatively thin, which will lead to the symptom of early eyelid swelling. 2. Visual fatigue: If you stay up late or use your eyes too much before going to bed, it will cause visual fatigue, affecting the blood circulation around the eyes, which will lead to the symptoms of early eyelid swelling. 3. Improper sleeping posture: If you like to sleep on your stomach, you may make the blood circulation in the eyes is not good, water retention in the microvessels, thus causing the symptoms of early eyelid swelling. 4. Drinking a lot of water before going to bed: If you drink a lot of water before going to bed, when you sleep flat on the face of the venous return resistance increases, blood circulation will be slowed down, thus causing the symptoms of early eyelid swelling. It is recommended that patients with early eyelid swelling develop good eye habits. If the symptoms are not relieved after resting, it is recommended to go to the hospital in time, to clarify the cause of the disease and standardize the treatment.
