Kidney stone disease (urolithiasis) is a common urological condition in which hard mineral deposits (stones) form in the kidneys or urinary tract. These stones may remain asymptomatic for a long time, but as they grow or move through the urinary system, they can cause severe pain, urinary obstruction, and other potentially serious complications. Early diagnosis and appropriately selected treatment help remove stones and reduce the risk of recurrence.

The thyroid gland plays a vital role in the functioning of the entire body by regulating metabolism, energy balance, and the activity of the cardiovascular and nervous systems. One of the key indicators of thyroid function is the thyroid-stimulating hormone (TSH). A TSH blood test helps doctors assess how well the thyroid gland is working and detect potential disorders at an early stage.

At the Helyos Medical Center, patients can undergo laboratory testing, have a thyroid ultrasound, and receive a consultation with an endocrinologist for an accurate diagnosis and personalized treatment plan.

What Is Thyroid-Stimulating Hormone (TSH) and What Does It Do?

Thyroid-stimulating hormone (TSH) is produced by the pituitary gland and regulates the function of the thyroid gland. It stimulates the production of thyroxine (T4) and triiodothyronine (T3), hormones that affect nearly every organ and system in the body.

When thyroid hormone levels decrease, the pituitary gland produces more TSH to stimulate the thyroid. Conversely, when T3 and T4 levels are too high, TSH production decreases. This is why a TSH blood test is considered one of the most important methods for evaluating endocrine system function.

Normal TSH Levels in Women, Men, and Children

Reference ranges may vary slightly depending on the laboratory and the testing method used. In most cases, the normal TSH range for adults is approximately 0.4–4.0 mIU/L.

TSH levels can be influenced by:

• age;
• sex;
• pregnancy;
• certain medications;
• underlying medical conditions.

During pregnancy, normal TSH values change, especially in the first trimester. Therefore, test results should always be interpreted by a healthcare professional.

In children, TSH levels also vary with age. Newborns typically have higher TSH levels, which gradually decrease and approach adult reference values as they grow.

When Should You Get a TSH Test?

A doctor may recommend a TSH test if you experience symptoms that may indicate thyroid dysfunction.

These symptoms include:

• persistent fatigue;
• drowsiness;
• sudden weight changes;
• dry skin;
• hair loss;
• irregular heartbeat;
• excessive sweating;
• insomnia;
• irritability;
• difficulty conceiving.

A TSH test is also commonly recommended during pregnancy, when planning pregnancy, to monitor thyroid disease treatment, and as part of routine preventive health check-ups.

Causes of High and Low TSH Levels

An elevated TSH level most commonly indicates an underactive thyroid gland (hypothyroidism). Possible causes include autoimmune diseases, iodine deficiency, the effects of thyroid surgery, or treatment with certain medications.

A low TSH level may occur in hyperthyroidism, a condition in which the thyroid gland produces excessive amounts of thyroid hormones. Changes in TSH levels may also be associated with pituitary disorders, severe stress, or the use of certain medications.

TSH test results should always be interpreted together with T3 and T4 levels, clinical symptoms, and the findings of additional diagnostic tests.

How to Prepare for a TSH Blood Test

To obtain the most accurate results, it is recommended to:

• have your blood drawn on an empty stomach;
• avoid intense physical activity the day before the test;
• avoid alcohol for 24 hours before the test;
• inform your doctor about all medications you are taking;
• whenever possible, have follow-up blood tests performed at the same time of day.

Following these recommendations helps ensure the most reliable laboratory results.

What Do Abnormal TSH Levels Mean and When Should You See an Endocrinologist?

An abnormal TSH level is not a disease itself but rather an indicator of a possible endocrine disorder. To determine the underlying cause, your doctor may recommend additional blood tests, a thyroid ultrasound, and other diagnostic procedures.

You should consult an endocrinologist if you experience symptoms of thyroid dysfunction, receive abnormal thyroid test results, or have a family history of endocrine disorders. Children with suspected thyroid problems should be evaluated by a pediatric endocrinologist.

Conclusion

Thyroid-stimulating hormone (TSH) is one of the most important indicators of thyroid function. A timely TSH blood test can detect thyroid disorders before noticeable symptoms develop, allowing treatment to begin at an early stage. Regular preventive check-ups, consultations with an endocrinologist, and modern diagnostic methods help maintain endocrine health and reduce the risk of developing serious thyroid and hormonal disorders.

Ears, nose, larynx, pharynx, larynx, pharynx, paranasal sinuses - all these belong to the group of ENT organs, the treatment, diagnosis and prevention of diseases of which is engaged in otolaryngologist. Regular visits to a specialist will allow you to avoid and prevent the development of very unpleasant diseases and complications. Helios Family Health and Rehabilitation Center provides an opportunity to make an appointment and visit an otolaryngologist at a convenient time and date. Both adults and children can come for an appointment.

When is it necessary to consult an ENT?

Not only painful sensations in the ears, throat, nose can be a motivation to visit an ENT office. There are many reasons for this. For example:

• Prolonged runny nose, occasional nasal congestion;
• Hearing loss;
• Loss of sense of smell;
• Fever in the throat, inflammatory process;
• Noise sensations in the ears;
• Ear stuffiness, wax plugs;
• hoarseness of voice;
• Difficult and painful swallowing;
• Frequent nosebleeds;
• Unmotivated dizziness, headaches.

Coming to the otolaryngologist it is important to tell all your complaints, as well as about previous diseases. A detailed anamnesis together with instrumental examination will help the doctor quickly, with high accuracy to determine the disease, make a diagnosis, prescribe adequate therapy.

What diseases does an otolaryngologist treat?

A number of different diseases of the respiratory and hearing organs are within the competence of the ENT doctor. Sinusitis, maxillary sinusitis, laryngitis, pharyngitis, otitis media, angina, pharyngomycosis, ozen, abscess, boils, malignant and benign tumors, deviation of the nasal septum, injuries to the nose, throat, ears, tonsillitis, tracheitis, infections of the ENT organs, problems with hearing, voice box, and so on. All this is diagnosed and treated by a specialist otolaryngologist.

In case of untimely referral to a doctor, left untreated symptoms, "neglected" diseases of the above can cause serious complications affecting other internal organs and body systems. Do not wait for an increase in the intensity of symptoms. It is better to go to the doctor immediately, when even minor signs of the disease appear.

Examination and diagnostic methods

ENT examination is prescribed by a specialist after visual examination, collection of anamnesis, palpation of lymph nodes and assessment of the condition of mucous membranes.

Diagnostic methods used in the Helios Medical Center are as follows:

• Video endoscopy;
• Audiometry;
• Functional diagnostics.

Therapy is prescribed depending on the results of the diagnostic examination. It can be photodynamic treatment, as well as with the help of drugs, lavage, purging, pressotherapy, puncture, removal of sulphur plugs, foreign bodies, irrigation with aerosols, other technologies.

The Helios medical center offers an individual approach to each patient. All laboratory and diagnostic tests are carried out in one place, which allows us to save time, make a diagnosis as quickly and accurately as possible, start treatment at early stages of the disease, and get the desired effect.
