Furosemide is the most dangerous and powerful diuretic: harm and side effects. Furosemide for weight loss: instructions for use

The diuretic Furosemide in bodybuilding is a popular diuretic drug that is used “for drying” on last week before the competition. Furosemide is one of the most powerful diuretics, as well as the most dangerous. In this article we will talk about the dangers of furosemide, side effects, and also talk about ways to mitigate its effects that bodybuilders use.

Diuretics (diuretics) are used to rapid removal water from the body. In bodybuilding, they help to “dry out” and achieve muscle definition; in other sports, they help to reduce weight in order to compete in a lighter weight category (boxing, horse racing, wrestling).

also in Lately diuretics are increasingly being used for weight loss, although it is obvious to those who understand the mechanism of their action that they have no effect on fat mass, but give only a temporary effect, removing a little more fluid from the body.

The initial purpose of diuretics was purely medical; they were used to reduce blood pressure for hypertension, treatment acute poisoning(to quickly remove toxins from the body) and in some other critical situations 1,2.

The use of diuretics is associated with enormous health risks and serious side effects, including death. From a certain point of view, they can be called the most dangerous pharmacological drugs in bodybuilding, even in comparison with anabolic steroids, drugs and hormones. Diuretics can make professional athletes writhe in convulsions on stage, and most deaths among pro bodybuilders are associated with their use.

Furosemide is one of the most popular and the most powerful diuretics in bodybuilding and, as a result, has the highest risk of harm to health and serious side effects.

What makes furosemide popular is its Very low price , especially if it is produced in third world countries (Mexico, China).

Its low price and truly very strong diuretic effect puts it out of competition, preventing other drugs from entering the market 3.

Diuretics act directly on the kidneys through various mechanisms. Some of them are more “mild” and relatively safe, while others are extremely strong, both in effect and in the severity of side effects.

Furosemide is a loop diuretic, which is one of the the most powerful and dangerous diuretics used in bodybuilding.

Mechanism of action of Furosemide

To understand the mechanism of action of Furosemide, and indeed all loop diuretics to which it belongs, knowledge of the anatomy and physiology of the kidneys is necessary, but let’s try to do this on in simple language sufficient to evaluate its effectiveness and side effects.

The kidney filters unnecessary substances from the blood and, in particular, cleans it of excess of certain ions that form electrolytes. Electrolytes are understood as internal fluids of the body (cells, intercellular spaces) that ensure the occurrence of biochemical reactions in the body, thanks to which the body lives.

In particular, thanks to normal functioning kidneys (which is equivalent to the correct balance of ions in the blood and cells) is ensured by maintaining normal blood pressure. The ions can be released into the urine from the blood as a result of filtration in the kidneys or, conversely, returned to the blood, depending on blood pressure. If it is high, more ions are removed; this leads to a decrease in blood pressure, since it is excreted into the urine along with ions. more water 1 .

Where does water come from?

The water that is removed in the urine is taken from the blood plasma (its aqueous part), and it enters the plasma from the space between the cells, including the skin and subcutaneous tissues. Exactly this intercellular fluid“erases” the muscle relief, giving the muscles flat view. What do diuretics do? They remove it.

Mechanism of action of furosemide, like absolutely all diuretics, is very simple: it prevents the absorption of sodium ions (their main source for the body is ordinary salt), which “bind” water. The removal of sodium is always accompanied by the removal of water.

Unpleasant consequences of Furosemide

As bodybuilders note, Furosemide and some other loop diuretics have one unpleasant consequence consumption: it acts very quickly, and is eliminated from the body in about 4-6 hours -> the body very quickly senses a large loss of water -> this leads to rapid replacement of water as soon as Furosemide is metabolized (excreted from the body) -> the unpleasant thing is that that in response to such “water stress” the body launches a compensation mechanism, accumulating it, resulting in the formation of edema.

Many bodybuilders note a characteristic unpleasant heaviness due to swelling when they stop taking Furosemide the day before the competition.

Cost of using diuretics: side effects and effects

The use of diuretics (Furosemide) cannot leave a lasting impact on the body. There is almost always a price to be paid for this in the form of serious side effects: when used, too many ions (electrolytes) can be “washed out”, since their effect is stronger than the function of the kidneys in maintaining the balance of ions.

Furosemide begins to act a few hours after consumption. However, it is obvious to us diuretic effect- far from the only one. Along with the excretion of urine, it almost always occurs. state of internal electrolyte imbalance, deficit important microelements, which can affect the functioning of the brain, muscles and heart. When the imbalance is very severe, the heart's rhythm becomes irregular and it may stop. When the heart stops, the body dies... and very quickly.

The main reason for the harm of furosemide and dangerous side effects is that it blocks the mechanism for the return of sodium, potassium and chlorides into the blood from filtered urine, and with them calcium and magnesium ions.

Why is this dangerous?

Important: There is a large amount of sodium and chloride in the bloodstream and interstitial fluid, so the loss of these two ions is not immediately felt. But there is much less potassium there, and it is its lack that causes the side effects or death characteristic of Furosemide (Lasix). Loss of calcium and magnesium can further increase potassium leaching, further increasing the extent of harm.

Let's illustrate with an example.

Side effects of Furosemide on the heart and muscles

Have you ever wondered why the heart beats?

The heart contracts due to an electrical impulse that travels throughout the heart muscle through a complex network of nerve fibers.

When an electrical impulse passes through a cell, it causes it to contract. But the most interesting thing is that the contraction and propagation of the impulse is carried out with the direct participation of potassium ions inside and outside the heart muscle cells.

Important: If the level of potassium outside the cell becomes too high or too low, it prevents the impulse from spreading, the rhythm is disrupted and the heart can stop.

This is a very life-threatening condition that can occur suddenly.

Another mineral important for heart health is magnesium, which is also washed out when using Furosemide.

It is probably the simultaneous deficiency of these two “heart” minerals (potassium and magnesium) that explains the extreme dangerous action Furosemide on the heart.

Calcium is another ion that is washed out when using Furosemide (Lasix). It is involved in muscle contraction 12. When calcium levels fall, weakness or muscle cramps(the muscle contracts and cannot relax). Obviously this can lead to serious problems for a bodybuilder while posing on stage.

The dangers of long-term use of the diuretic Furosemide for weight loss

All of the above side effects can occur even with short-term use of diuretics, as bodybuilders do (they are usually used only in the last week of “cutting” before competitions).

Long-term use of diuretics (for weight loss, for example) is associated with even more high risks harm, including an even higher risk of death due to cardiac arrest and metabolic disorders. This is due to the fact that the body experiences a chronic deficiency of minerals important for life.

In addition to the health hazards listed above, they reduce physical performance and exercise tolerance, impair the body's ability to regulate temperature, leading to dehydration, weakness and poor circulation.

Conclusion

Furosemide is popular and powerful loop diuretic, which is really capable of quickly removing great amount fluids from the body, give the body a brutal relief appearance and even create quick effect"weight loss"

Furosemide, like many other diuretics, affects the kidneys by blocking the return of vital mineral ions to the bloodstream, causing excretion more water into urine, which is taken from the space between cells. It is this intercellular fluid that hides the muscle relief from prying eyes.

The use of Furosemide in bodybuilding leads to a deficiency of potassium and magnesium, which can cause irregular heartbeat And sudden death . Even low doses of the drug in a dehydrated person can increase blood viscosity or poor circulation (usually due to too low blood pressure).

Important: Furosemide may seem to be enough safe medicine, as it is “just” a diuretic and not a powerful hormone, steroid or drug. However, he is one of the most dangerous drugs ever used in bodybuilding.

If you ever decide to try Furosemide or any other diuretic for yourself, always be aware of the enormous risk of serious side effects.

Despite the fact that getting rid of extra pounds with the help of some medications has a number of contraindications and side effects those who want to become slimmer and more beautiful continue to try to find universal method to achieve the desired result.
