If the swelling of the eyes in the morning is caused by physiological factors such as drinking too much water before going to bed and eating improperly, no treatment is usually needed. If it is caused by diseases such as granuloma and chalazion, medication and surgery should be taken to treat the cause. 1. Physiological factors: Drinking too much water before going to bed and eating too much food with high water content will cause your eyes to swell in the morning. If there are no other uncomfortable symptoms, no special treatment is needed. Appropriate activities, the symptoms can be relieved. 2. Emphysema: Swollen eyes in the morning may also be caused by emphysema. Patients need to use antibiotic drugs under the guidance of the doctor, such as levofloxacin eye drops, erythromycin ophthalmic ointment and so on. If an abscess is formed, it needs to be cut and drained in time. 3. Chalazion: Swollen eyes in the morning is also considered to be caused by chalazion. Patients can follow the doctor’s instructions for local injection of glucocorticoids, such as trimethoprim and dexamethasone, so as to reduce the size of the chalazion, in order to facilitate the operation. Once the size is reduced, chalazionectomy can be performed. There are many causes of swollen eyes in the morning, and it is recommended that patients promptly identify the cause of the disease and actively cooperate with doctors to take treatment measures.
