Take thyroxine for weight loss - is a risky business, especially if such a treatment is carried out without a prescription, and a preliminary examination. Depending on the function of the thyroid gland, adrenal gland and cardiovascular systems it may lead to various complications.

Action thyroxine

Thyroxine - is iodine-containing thyroid hormone Thyroid hormones: mechanism of action and physiological effects . Its synthetic analogue - L-thyroxine is used as a drug for treating some diseases - after ingestion has the same effect as the natural hormone.

Thyroxine has a variety of actions: it is essential for the normal development of the growth and development of tissues, stimulates the cardiovascular activity, all types of exchanges, conducting nerve impulses, enhances the absorption of the tissues of oxygen and heat production, increases the activity of certain enzyme systems. Metabolic processes are activated particularly in the cardiac muscle, skeletal muscle, liver and kidney.

In some cases, prescribe thyroxine slimming

Slimming a L-thyroxine is used only on strict conditions, when the increase in body weight is associated with reduced function of the thyroid gland. This may be caused as diseases of the thyroid gland, and diseases of regulating its function - the pituitary and hypothalamus.

Decrease of thyroid function leads to a decrease in metabolic rate, and this in turn to the accumulation of fat in the body. In such a case as intended endocrinologist being treated with L-thyroxine, which accelerates all metabolic processes and fat burning.

At the same time it contributes to a L-thyroxine withdrawal and other symptoms of hypothyroidism Hypothyroidism - Symptoms: What should pay particular attention : Subcutaneous edema (they can also be the cause of weight gain), disorders of the cardiovascular system and the central nervous system. Hypothyroid patients receiving permanent replacement therapy can lead a normal life, the quality of which does not differ from the quality of life of healthy people. But in order not to have health problems with hypothyroidism, it is necessary to adjust the dose of L-thyroxine replacement therapy for long.

Do all you can to take thyroxine for weight loss?

In order to reduce the weight by using thyroxine required to take very large doses of the drug. Sometimes they far exceed the dose recommended for drug treatment with L-thyroxine Thyroxine - the main thyroid hormone .

A L-thyroxine at therapeutic doses can be taken for years without any consequences. If the daily dose exceeds the recommended, the risk of side effects is greatly increased, and at some point it becomes a perfect match.

Therefore, a L-thyroxine slimming without a strict indications for this in the form of decreased thyroid gland does not apply.

In addition, some people can not be applied thyroxine - for receiving this drug has a number of contraindications, which should take into account the doctor. This hypersensitivity to the drug of the patient, untreated hyperthyroidism, untreated adrenal insufficiency, acute cardiovascular disease, lack of enzymes which decompose in the intestines of simple sugars or impaired absorption of food in the small intestine.

The caution is recommended to appoint a L-thyroxine in cardiovascular diseases, diabetes, severe long-existing hypothyroidism.

What complications can cause an overdose of L-thyroxine

The greatest risk of complications when taking thyroxine haphazard threatened by the cardiovascular system. The toxic effects of large doses of thyroxin on the heart and blood vessels can be very significant.

This creates an increased load on the heart, and after some time the heart muscle can not stand it - the heart stops pumping the needed volume of blood, it leads to its stagnation in the venous system and the development of cardiovascular disease with shortness of breath and increasing edema.

Increased protein breakdown leads to muscle weakness and decreased immunity. It appears fast muscle fatigue, constant weakness, tremors in the limbs and throughout the body.

In most cases there is the development of osteoporosis (bone brittleness due to loss of calcium), the accumulation of a large amount of potassium in the bones and impaired general motor activity. Complications of the central nervous system are irritability, tearfulness, anxiety Anxiety - how to distinguish normal from disease? , Insomnia, nervous exhaustion.

Thyroxine is not used for weight loss without the presence of this evidence.

  The thyroid gland - a small gland located in the neck, behind the front of the trachea and larynx. The thyroid gland produces two hormones - thyroxine (T4) and triiodothyronine (T3), which regulate the metabolism (digestion of food coming into the body and distribution of energy). Thyroid gland regulates another - so-called pituitary gland, or the pituitary gland, located at the base of the brain and produces a thyroid stimulating hormone.

Hormones produced by the thyroid gland, practical effect on the operation of all systems of the human body to regulate oxygen consumption, generation and distribution of energy.

Hyperthyroidism

A condition in which overactive thyroid causes excessive secretion of thyroid hormones, called hyperthyroidism. It is a disease of the thyroid gland increases metabolism Improves metabolism and losing weight without dieting   and it occurs in one percent of all women who are faced with hyperthyroidism much more often than men. One of the most common forms of hyperthyroidism - the so-called Graves' disease, an autoimmune disorder that is inherited. The exact nature of the genetic abnormality is unknown.

Hypothyroidism

Deficiency of thyroid hormones caused by a decrease in the function of the thyroid gland, called hypothyroidism. In hypothyroidism there is slowing of metabolism. There are several main reasons for hypothyroidism, most of which directly affect the thyroid gland, disrupting the production of hormones. In very rare cases, the cause of hypothyroidism are tumors in the pituitary gland to block the production of thyroid stimulating hormone. As a result, the thyroid gland does not produce enough for normal functioning of body systems the amount of hormones.

Whatever the reason, resulting in hypothyroidism there is a shortage of thyroid hormones and, consequently, slow down various body systems. The body uses less oxygen and produces less power.

Thyroid nodes

Thyroid node - a small degree or nodule in the thyroid gland. Thyroid knots - quite common: they are either fluid-filled cysts that form node in the thyroid or nodules in the breast tissue. Nearly half of all people at a certain age is faced with thyroid nodes, but in most cases these formations are too small and therefore invisible. Only five percent of cases of thyroid nodes to develop significant (about one centimeter) size and affect the normal size of the thyroid gland.

Furthermore, in some cases of thyroid growth nodes may cause difficulty breathing or swallowing process.

Thyroid disease and irregular heartbeat

People with an overactive thyroid (hyperthyroidism) increased risk of atrial fibrillation - a violation, a characteristic feature of which is an irregular pulse.

Hyperthyroidism occurs when the thyroid gland produces too much thyroxine Thyroxine - the main thyroid hormone   (thyroid hormone), causing the acceleration of many processes in the body. Approximately one out of a hundred women and one out of a thousand men in this or that period of life is revealed hyperthyroidism; it can develop into absolutely any age.

It is well known that clinically significant hyperthyroidism can cause atrial fibrillation, but it is not clear whether the softer (subclinical) form of this disorder have the same effect. Information about the risk of atrial fibrillation in patients with hypothyroidism (decreased activity of the thyroid gland) is also limited.

Therefore, recently, scientists have decided to study the link between atrial fibrillation and a spectrum of thyroid disease in a large group of patients. Several countries have studied history 586 460 patients who had a blood test for details thyroid-stimulating hormone. In people with hyperthyroidism levels of this hormone are usually low in patients with hypothyroidism - is high. During the median follow-up duration of 5.5 years, 17 154 (3%) patients were diagnosed with atrial fibrillation. 53% of patients were women.

According to a study in patients with subclinical hyperthyroidism risk of atrial fibrillation was increased by 30%, while in patients with normal thyroid function, he was 12%. In patients with hypothyroidism, the likelihood of developing this disorder even lower.

The researchers emphasize that despite the findings to prove a direct causal link between hyperthyroidism and arterial fibrillation has not yet succeeded. Meanwhile, however, it can be assumed that adequate treatment of hyperthyroidism can, at least to some degree, helping to avoid problems with the heart.

Lithium-induced thyroid disease

Lithium - a drug used for the treatment of acute mania, unipolar and bipolar depression Depression - a little more than a bad mood And for the prevention of bipolar disorders. Thyroid disease associated with taking lithium, have long been known and is often referred to in medical literature. Among these diseases - goiter, hyperthyroidism, hypothyroidism, and autoimmune thyroiditis.

Lithium affects the thyroid gland by different mechanisms. At the cellular level, it reduces the synthesis and secretion of thyroid hormones. It also affects the peripheral deiodination of T4, because of which the level changes of thyroid hormones.

Hypothyroidism and goitre - the most common thyroid disease among patients taking lithium. Lithium-induced hyperthyroidism is very rare.

It is also noted that lithium increases the risk of autoimmune thyroiditis in patients who already have a tendency to this violation; this is due to the fact that the drug is able to increase the activity of B-lymphocytes.

More frequent examinations are required for women over 50, patients in whose family history of thyroid disease, as well as those who have thyroid antibodies in the analysis gave a positive result.

Other diseases

The number of less common diseases include thyroid cancer, thyroid cancer Thyroid cancer: it is curable , Thyroiditis (swelling of the thyroid gland), goiter (swelling of the thyroid gland).
