Kidney disease: for example, nephrotic syndrome, etc., due to hypoproteinemia will cause edema, starting from the face first swelling.

Facial edema cough may also be caused by other diseases, it is recommended that if it is not relieved or aggravated, please consult a doctor in time to clarify the cause of the disease and then actively treat it.
