What Is A Diuretic And What Is It Used For?

A diuretic is a diuretic. These drugs are often used to treat high blood pressure or kidney disease.

What is a diuretic and what is it used for?

A diuretic is a medicine that helps you pass urine. So it helps to remove water and electrolytes from the body through the urine. Many people also call these diuretics “water tablets”. Because they act on the kidneys in such a way that they release more sodium and more water into the urine.

In this way, a diuretic reduces the amount of fluid that flows through the blood vessels. This in turn reduces the pressure exerted on the vessel walls by the blood itself.

Although many people don’t know, a diuretic doesn’t have to be a drug. Because there are numerous foods that achieve the same effect naturally. In addition, they are very useful for treating many diseases in other ways.

For example , a diuretic can be used in the treatment of high blood pressure or heart failure. That’s why in this article we explain everything you need to know about diuretics. And what purposes they are usually used for.

How does a diuretic work?

As mentioned earlier, a diuretic usually works by causing the kidney to excrete more electrolytes and more water in the urine. By increasing the flow of urine, there is a decrease in the total amount of blood circulating in the vessels.

It is important to know that there are different types of diuretics. These are classified according to their mechanism of action. That way they can act much more effectively. Because they are then used for a very specific medical treatment. The different groups of diuretics primarily include :

  • Thiazide diuretics: These inhibit the uptake of sodium and chloride in the kidneys. In this way you reduce their amount and the amount of fluid in the blood. Plus, these are the only ones that allow blood vessels to widen. That is why they are mainly used to treat high blood pressure.
  • Potassium-sparing diuretics: The effect is practically the same as that of the thiazide diuretics just discussed. However, they prevent the loss of potassium from the urine. And this is important for certain diseases that are caused by an imbalance in the potassium balance.
  • Loop diuretics: Again, the mechanism is similar to that of thiazide diuretics. In fact, they are often combined with each other. They are used in acute treatment because of their high effectiveness in increasing urine production.

    What exactly is a diuretic used for?

    Diuretics can be used for a variety of purposes. They are primarily used as a medicine to treat certain diseases. For example, they are used in heart failure.

    With heart failure, the heart is unable to efficiently pump oxygen-rich blood to all parts of the body. As a result , blood collects in certain areas of the organism over time.

    As a result, fluid then reaches the so-called interstitial tissue. That also means z. B. in the lungs or in the legs. This amount of fluid can then be reduced by using a diuretic. So the heart becomes more efficient again.

    In addition, diuretics are also used for various kidney diseases and liver diseases or for the treatment of edema. Likewise, it’s important to know that they are especially important in treating high blood pressure.

    Nevertheless, the prevailing opinion among many people is that a diuretic is also useful for losing weight. But this is by no means the case. This is because diuretics help reduce the amount of fluid that builds up. But they don’t burn fat.

    It’s true: you can make it look less bloated by taking diuretics. Therefore, you then draw the wrong conclusion that you have lost weight. But that’s because you lost fluids, not because you lost excess fat. In fact, taking diuretics can put you at risk of dehydration. So you should only use these remedies on medical advice.

    What foods are natural diuretics?

    The following foods are considered to be natural diuretics: celery, beetroot, pears or cucumbers. And of course watermelons and asparagus are also part of it, which many already know. But don’t forget to combine these foods with a correct and sufficient intake of fluids.


    A diuretic is a medicine that helps remove more water and electrolytes from your urine. These diuretics help reduce the total amount of blood. This is important in the treatment of some diseases, such as: B. high blood pressure, very beneficial.
