After women take diuretics orally, there may be a decrease in blood pressure, a decrease in metabolite accumulation, weight loss, water-electrolyte disorders, allergies, impaired renal function and other states. Women should use drugs under the guidance of a doctor to avoid unauthorized use of drugs, causing unnecessary harm. 1, blood pressure reduction: if the female patient has hypertension, after the application of diuretics, a large number of circulatory system from the filtration, or excess water, thereby reducing the volume of the circulatory system, so that the pressure of the blood vessel wall decreases, so as to achieve the purpose of lowering the blood pressure. 2, metabolite accumulation reduction: if the female patient kidney function is not good, in the period of recovery of kidney function, the metabolites are reduced, and the metabolites are not stored in the bloodstream. If the female patient’s kidney function is not good, in the period of recovery of kidney function, short-term application of diuretics, can help to strengthen the kidneys for the circulation of the blood system filtration and cleansing effect, can prompt the kidneys to the blood of a large number of metabolites, through the urine out of the body, to avoid toxic metabolite accumulation in the body, damage to the heart or liver function; 3, weight loss: women oral diuretics will lead to a substantial increase in the number of times of urine, accompanied by the amount of urine each time, the number of times of urine, and the amount of urine. At the same time with the amount of urine each time also increased accordingly, the body contains water decline, may cause women to lose weight accordingly; 4, water electrolyte disorders: if women take oral diuretics for a long time, due to a large amount of urine out of the body, will lead to excessive loss of potassium, sodium and other necessary trace elements, resulting in electrolyte disorders, so may cause hypokalemia; 5, allergy: if the female patients on the If female patients are allergic to sulfonamides, after applying thiazide diuretics such as furosemide and torasemide, cross-allergic reaction may occur, insulin resistance and hyperglycemia may occur, thus aggravating diabetes mellitus; 6. impaired renal function: if female liver function is relatively normal, after taking diuretics orally, due to the loss of large amounts of fluid in the body, it may lead to the decrease of effective blood circulation, causing insufficient perfusion of female kidneys, and may even cause acute kidney injury and other conditions. The status of female patients suffering from different diseases after taking oral diuretics varies and should be analyzed and judged according to the actual situation.
