TSH analysis allows you to monitor the activity of the thyroid gland and makes it possible to identify the presence of a threat of hormonal disorders in the body. The level of its content in the blood of men is subject to many factors, including age and health.
The value of TSH for men
The TSH test helps to determine the content of thyrotropin, which is responsible for the functioning of the thyroid gland. The male body is very dependent on the state of this gland, which controls most of the metabolic processes in the body. Therefore, it is very important for him to maintain thyroid-stimulating hormone within the required values, which is produced by the cells of the pituitary gland.
The normal operation of the following systems depends on the condition of the thyroid gland:
In addition, it affects the functioning of the musculoskeletal system, blood vessels and heart. Violation of the TSH norm for men can lead to a thyrotoxic crisis or hypothyroid coma. Without the presence of the required amount of thyrotropin, the thyroid gland will not be able to produce the required amount of hormones, which will necessarily reduce the rate of metabolic processes in the body, negatively affect immunity, the mechanisms of thermoregulation, the ratio of the amount of calcium and phosphorus. All these negative phenomena can directly affect the quality of life of a man and his performance.
The test is taken by all males suffering from an enlarged thyroid gland, hypo- and hyperthyroidism. It is performed in the morning, when the concentration of this hormone in the blood is maximum, always on an empty stomach. For a few days, you should exclude the intake of aspirin-containing drugs, antipsychotics, adrenergic blockers and the passage of an X-ray study. The level of TSH in men is also significantly influenced by their emotional state. Therefore, in order to avoid a false result, all stress and anxiety must be minimized.
TSH, the norm of which in men varies in the range of 0,4-4,1 mU/l, and increases when the content of other thyroid hormones decreases. The inverse relationship also persists – a high level of T3 and T4 hormones entails a decrease in TSH.
This hormone is very sensitive to the smallest changes in the thyroid gland, starting to be produced in large quantities. In addition to endocrine diseases, an increase in the content can be observed with damage to the pituitary gland and its tumors. Therefore, when an overestimated TSH index is obtained, an assessment of other components of a man’s blood is required. If they also deviate from the norm, then most likely the patient has a pituitary gland pathology. In other cases, an increase in hormonal levels is caused by disorders of the thyroid gland.
In addition to these diseases, TSH may be overestimated if a man regularly plays sports, works physically, works in hazardous industries, or has recently undergone anesthesia.
The table below very clearly shows the dependence of the TSH hormone norm on the number of years lived. It classifies the change in normal values by age in male patients.
|Up to 3 months||0,5-10,1 mU/l.|
|5 years||0,3-6,1 mU/l.|
|15 years||0,3-5,1 mU/l|
As you can see, the boundaries of the norm change throughout life, and the highest values are observed in newborn boys. The values given in this table are used by endocrinologists to assess the quality of the thyroid gland in men. At the same time, insignificant deviations from them do not indicate serious pathological changes.
The main symptoms and their causes
Detonic – a unique medicine that helps fight hypertension at all stages of its development.
The complex effect of plant components of the drug Detonic on the walls of blood vessels and the autonomic nervous system contribute to a rapid decrease in blood pressure. In addition, this drug prevents the development of atherosclerosis, thanks to the unique components that are involved in the synthesis of lecithin, an amino acid that regulates cholesterol metabolism and prevents the formation of atherosclerotic plaques.
Detonic not addictive and withdrawal syndrome, since all components of the product are natural.
Detailed information about Detonic is located on the manufacturer’s page.
Elevated TSH levels
can indicate the presence of a variety of diseases. Usually this deviation is accompanied by the following symptoms:
- Weakness and fatigue;
- Decreased performance;
- Thinning and hair loss;
- Arrhythmias and bradycardia;
- Decrease in blood pressure;
- Unexplained weight gain
- Loss of cold sensitivity;
- Gastrointestinal disorders;
- Impairment of memory and ability to concentrate;
- Deterioration of potency;
- Muscle weakness;
- Puffiness around the eyes.
The condition in which the concentration of this hormone is increased is called hypothyroidism. What does it mean? The hormones T3 and T4 are produced by the thyroid gland in insufficient quantities. The following diseases are considered the main causes of such a violation:
- Decreased thyroid function;
- Tumors of the pituitary and adrenal glands;
- Psychosomatic disorders.
An increase in concentration also occurs if ectopic secretion of TSH (lung, breast tumors) occurs. The concentration increases in case of severe somatic diseases (convalescence phase), or if there is a syndrome of resistance to thyroid hormones.
The use of drugs such as amiodarone, beta-blockers (atenolol, metoprolol, propranolol), X-ray contrast agents, antipsychotics (phenothiazine derivatives, aminoglutethimide), clomiphene, antiemetics (motilium, metoclopramide), anticonvulsants (phenyzepintoin), carbodamide-containing drugs drugs (for example, solutions for sterilizing the skin), lithium salts – can also lead to an increase in values.
All conditions in which there is an increased content of thyroid-stimulating hormone in men require medical intervention. Correctly chosen treatment tactics will help prevent the development of complications and normalize the activity of the thyroid gland.
Not always, in the case of deviations, the TSH is increased. A considerable number of men suffer from the opposite condition, which is characterized by an increase in the content of hormones T3 and T4, and a decrease in the level of thyroid-stimulating hormone.
In these cases, patients have the following symptoms:
- Increased sweating during sleep;
- Chronic diarrhea
- Sharp weight loss.
In addition to these symptoms, men may experience such delicate problems as decreased libido, loss of fertility, and a drop in testosterone in comparison with normal values. A decrease in TSH can also lead to the development of osteoporosis.
A decrease in TSH from the norm is most often caused by the following diseases:
- Diffuse toxic goiter;
- Euthyroid syndrome;
- Pituitary gland pathology;
- Plummer’s disease;
- Exhaustion of the body;
- Mental disorders;
- Itsenko-Cushing’s disease.
A decrease in the amount of TSH in the blood may be associated with the intake of drugs such as corticosteroids, dopamine, thyroxine, triiodothyronine, amiodarone, cytostatics, beta-adrenergic agonists (dobutamine, dopexamine), somatostatin, octreotide, nifedipine, drugs for the treatment of hyperprolactinemia (meteribedergoline, bromocriptine), heparin, acetylsalicylic acid preparations.
TSH levels are often low as a result of inadequate nutrition and inappropriate lifestyle choices. It can be caused by fasting or harsh diets such as postoperative diets. Due to the fact that the activity of the endocrine system depends on the iodine content in the body of a man, it can be partially regulated by changing the amount of iodine-containing products in the diet.
