Why do I gain weight the next day if I drink water before going to bed?

If you drink water before going to bed and gain weight the next day, it is usually because the water in the body cannot be metabolized, which leads to weight gain the next day.

Normally, it is normal for a person's daily weight to fluctuate within two kilograms. It is natural for the human body to eat and exercise every day, and different weight increases and decreases. Fluctuations within two kilograms are within the normal range. If the patient's weight continues to increase or decrease every day, it is a disease. For example, if the patient's weight increases by two kilograms every day, it is a disease. It is necessary to check whether the patient's diet is not controlled, the amount of exercise is too little, or the excitatory hormone disease of the body's metabolism has occurred. If the patient loses weight every day and loses 10% of his original weight within a month, he should be checked for metabolic diseases.
