There are more reasons for the recurrent swelling of the face, and the following reasons are common in clinical practice: First, patients drink too much water before going to bed at night, and the metabolic rate of the body is slower during sleep, so the excess water in the body cannot be excreted in time, resulting in the phenomenon of swelling of the face. Patients often eat food with high salt content, and salt can easily lead to water retention in the body, which cannot be discharged in time, resulting in swelling of the face. Patients may suffer from certain kidney diseases, heart diseases, endocrine diseases and other symptoms, and swelling of the face is one of the main symptoms. Patients should go to the hospital for a detailed examination at this time, and then carry out targeted treatment after diagnosing the cause clearly. Fourth, the patient’s face is affected by allergens, so that the facial skin is stimulated to cause puffiness. Patients should regularize their work and rest time, avoid staying up late, avoid allergens, strengthen physical exercise, and promote metabolism, which will help to relieve the swelling phenomenon.
