How long diuretics should be taken continuously cannot be generalized, but needs to be decided in the light of the condition, diuretic effect, and the presence of electrolyte disorders. If the condition requires, the time of taking diuretics should be based on medical advice. When taking oral diuretics, if the diuretic effect is poor, not to achieve the effect of excreting excess water in the body, you can extend the time of taking. When diuretics expel water from the body, they also expel electrolytes such as sodium and potassium. In addition, when water is excreted excessively, it may lead to a decrease in blood volume and low blood pressure. When these conditions occur, diuretics need to be suspended. Diuretics should be used correctly under the guidance of a doctor, and if there is any discomfort during the taking of diuretics, it is necessary to consult a doctor in time to avoid accidents.
