Puffy eyes and face are often caused by bad habits such as lack of sleep, localized inflammation of the eyes, allergies, and systemic pathologies. 1. Lack of sleep: Bad habits such as pressure on the eyes while sleeping and drinking too much water before going to bed may lead to impaired blood return around the eyes, and eyelid swelling may occur. 2. Localized inflammation of the eyes: Acute dacryocystitis and orbital cellulitis due to bacterial infection, etc. may cause swelling of the eyes and face, mostly accompanied by pain when pressed. 2. Allergy: the skin of eyelids and face will be swollen due to allergic reaction caused by contact with external allergens, mostly accompanied by itching. 4. Systemic lesions: such as kidney disease, thyroid disease, hypertension, diabetes and other pathologies, may lead to bilateral swelling of the eyes and face. When there is eye and face swelling that cannot be relieved by rest, you need to go to the hospital in time to clarify the specific cause and follow the doctor’s instructions for treatment.
