Causes of weight change in a short period of time
The usual reason
The change of human body weight is not only related to the different weight of clothes worn when weighing, but also related to the real-time "in and out" of various systems of the body such as diet, drinking water, sweating (including hidden sweat), excretion, breathing and hormone levels. For example, if you eat too much rice, you will gain weight 1 kg, and if you sweat too much, you will lose 2 ounces.
exceptional case
Some special circumstances may also cause small fluctuations in weight in a short time, such as food poisoning, infection and other symptoms may lead to weight loss, or menstrual women may also cause edema due to changes in hormone levels, resulting in weight gain.
drug effect
In addition, some drugs such as glucocorticoid may lead to weight gain, and topiramate, an antiepileptic drug, may reduce the weight of epileptic patients by affecting appetite and taste. Hypoglycemic drugs such as insulin, metformin and acarbose also have different effects on weight gain and loss.
How often and when should I weigh myself?
Many people weigh themselves several times a day when they lose weight, once to see how much they have gained after a meal, and once to comfort themselves that they have lost a little weight after going to the toilet ... In fact, this is a kind of anxiety to lose weight, and the fluctuation of weight loss data in one day is not of great reference significance, because due to changes in environment, diet, activities and other factors, it is actually normal for the weight to fluctuate up and down within the range of 2.5kg at different times.
It is recommended to weigh it once a week during weight loss, because it is normal to have fluctuations within two or three days. The actual weight loss effect is suggested to be seen in a few weeks. It is suggested that the time for weighing each time is after defecation every morning and before breakfast. The weight measured by wearing light clothes is often the lowest value in a day, and then compare the weight value of one week horizontally to see if there is any overall weight loss. If you lose weight through a healthy diet and proper exercise, it is more appropriate to lose 2-4kg per month.
Losing weight is not necessarily a good thing.
People eat fat bit by bit, and thin is of course a little thin, so when your weight drops sharply in a short time, and you don't control your diet or increase your exercise, you should be alert, which may be a signal of some diseases. 1-3 months of sudden weight loss of more than 5%, but it may be a signal of some diseases, such as diabetes, cancer, hyperthyroidism, gastrointestinal diseases and so on.
Of course, if weight loss is really caused by disease factors, it will usually be accompanied by other related symptoms. For example, diabetic patients may have symptoms of drinking, eating and urinating at the same time, so when the body is obviously thin. And there are other symptoms of discomfort, please go to the hospital in time to check if you are sick, instead of being immersed in the joy of losing weight, thinking that losing weight is effective.
In short, the weight value is only a concrete reference value, and mentality and methods are the two magic weapons to maintain a healthy weight.
