It is a normal physiological phenomenon that you weigh the same in the morning as you do in the evening. There are many factors affecting the weight of a day, including the amount of food intake, excretion, and clothing, etc. Therefore, relative to normal people, the above factors do not have significant changes in the case, the weight of a day between the weight may occur some slight changes, but the overall change is not significant, the chances of appearing exactly the same are also relatively low. Due to the influence of some disease factors or drug factors, it will affect the excretion of intestinal contents and the discharge of water and sodium, so there will be a more obvious change in weight within a day. When the weight is abnormal, you must go to the hospital in time and ask the doctor to analyze it with your own situation.
