Clinical diuretics are taken to lose up to 1kg a day. Diuretics include tab diuretics, thiazide diuretics, potassium-protective diuretics, etc. Regardless of which type of diuretic is applied to the body, it means that the body may experience inappropriate retention of water in the body, which means that edema occurs. If diuretics are applied in higher doses, the body weight can be reduced a lot. However, in order to ensure the safety of the body, the clinical practice is not to reduce the body weight by more than 1 kg every 24 hours. If more than 1kg of weight reduction is applied, it may cause serious ionic disturbance or cause insufficient blood volume, which may lead to insufficient blood supply to certain vital organs, such as heart, lungs, liver, kidneys and organs in the brain. Therefore, no matter what diuretic is applied to reduce swelling, weight should not be reduced too quickly, and serious consequences may occur if it is reduced too quickly.
