Morning edema can be caused by drinking too much water before going to bed, kidney disease or liver disease. It can be improved by reducing the amount of water consumed before going to bed and taking medication as prescribed by the doctor. 1. Drinking too much water: If it is caused by drinking too much water before going to bed, you can use a cold towel on the face in the morning, which can promote the contraction of local capillaries and reduce swelling. 2. Kidney disease: edema may be caused by kidney failure, nephrotic syndrome or other kidney diseases. You can use diuretics and edema-reducing drugs such as furosemide and torasemide under the guidance of your doctor. 3. Liver disease: If it is caused by active replication of Hepatitis B virus, you need to use entecavir and lamivudine as prescribed by the doctor. If it is caused by autoimmune liver disease, it can be treated with prednisone, methotrexate and other drugs. Sodium and water intake should also be strictly limited to correct electrolyte disorders. These are only some of the common causes. If the symptoms persist, you should consult a doctor for a clear diagnosis and standardized treatment. The use of drugs must follow the doctor’s instructions, not blindly use their own drugs, so as not to cause adverse consequences.
