If a patient has upper eyelid swelling every morning, the following diseases should be considered: 1. Endocrine metabolic diseases, such as hypothyroidism and adrenocortical insufficiency, can cause varying degrees of sodium and water retention, which can lead to upper eyelid swelling in the morning. 2. Patients with chronic cardiac insufficiency may also be prone to upper eyelid swelling in the morning. In particular, in right heart failure and total heart failure, the swelling of the periphery, forehead and even lower limbs is relatively significant. 3. Patients with malnutrition, such as anemia or severe malnutrition, may also have swollen eyelids in the morning, usually as a result of hypoproteinemia. 4. This is because the body produces hypoproteinemia after a large amount of proteinuria, which causes puffy eyelids.
