When dehydration is serious, it will cause collapse and even life-threatening, so it is necessary to supplement body fluids by infusion. According to the change of blood sodium or osmotic pressure, dehydration is divided into hypotonic dehydration, that is, extracellular fluid reduction combined with hyponatremia; Hypertonic dehydration refers to the decrease of extracellular fluid combined with hypernatremia; Isoosmotic dehydration refers to the decrease of extracellular fluid and normal blood sodium.
Dehydration to lose weight is very common among people who lose weight, because they can pursue rapid weight loss and ignore the common phenomenon caused by whether the drugs used really have weight loss effect. Common does not mean harmless.
The food eaten every day will generally decrease, and the actual calorie intake will also decrease every day. If people can't consume enough calories every day, then the body will mobilize its stored energy substances to supply energy.
Extended data:
1, weight loss does not pursue rapid weight loss.
Many people pursue fast weight loss, but the real weight loss is fat loss, and the weight loss speed is relatively slow. So many people think they have lost weight. They only eat vegetables and fruits because of hunger. Hunger and exercise lose water, bones and protein's weight. The resulting problems are decreased metabolic rate, decreased immunity and accelerated aging.
2. To lose weight quickly is to lose muscle.
Lose 1 kg muscle, lose more than 3 kg, because protein will combine a lot of water, and muscle contains 20% protein and 70% water. So if you lose fat, you only have 1 kg of fat. If you lose 1 kg of pure muscle, you will lose 3.5 kg of water accordingly. Weight loss caused by protein reduction is very rapid and significant.
