MYOSITIS: WHAT PATIENTS NEED TO KNOW

Muscle pain and weakness are symptoms that many people attribute to fatigue or a cold. However, they can sometimes be signs of a serious condition—myositis. Understanding this condition will help you see a doctor in time and start the right treatment.

What is myositis?

Myositis is an inflammation of muscle tissue. The term “myositis” encompasses both common inflammation following overexertion or exposure to cold, as well as serious autoimmune diseases: polymyositis, dermatomyositis, and necrotizing autoimmune myopathy.

In autoimmune forms, the immune system mistakenly attacks the body’s own muscles, causing chronic inflammation. Without treatment, this can lead to persistent weakness, muscle atrophy, and serious complications.

How to recognize myositis: main symptoms

Look for the following signs:

•       Muscle weakness—especially in the shoulders, hips, and neck; difficulty getting up from a chair or raising your arms.

•       Muscle pain—may be constant or worsen with movement and palpation.

•       Increased fatigue—even after minimal physical exertion.

•       Muscle atrophy — with a prolonged course of the disease, muscle mass may decrease, and strength and endurance may decline.

•       In dermatomyositis, characteristic skin rashes may appear: redness around the eyes (the “goggle” sign), and rashes on the finger joints.

•       Possible difficulty swallowing or shortness of breath — if the throat muscles and respiratory muscles are affected (this requires immediate medical attention!).

⚠ Important: If you experience severe shortness of breath, difficulty swallowing, or a sudden worsening of your condition, contact a doctor immediately or call an ambulance.

Why does myositis occur?

The causes can vary:

•       Autoimmune processes—the most common cause of chronic myositis.

•       Viral and infectious diseases—the flu, strep throat, and other infections can trigger muscle inflammation.

•       Injuries and excessive physical exertion.

•       Exposure to cold and prolonged exposure to drafts.

•       Taking certain medications (for example, statins—drugs used to lower cholesterol).

•       Concomitant connective tissue diseases (lupus, scleroderma).

•       Cancer — in some cases, myositis may be the first sign of a tumor.

Treatment and rehabilitation

According to the clinical guidelines of the Ministry of Health of Ukraine, treatment is selected based on the form and cause of myositis. Properly prescribed therapy significantly influences the course of the disease and the prognosis.

Drug treatment

•       Corticosteroids (e.g., prednisolone)—the main treatment for autoimmune myositis, reduce inflammation.

•       Immunosuppressants (methotrexate, azathioprine) — prescribed when corticosteroids are not effective enough.

•       Anti-inflammatory drugs — to relieve pain and swelling.

•       Antibiotics — if myositis is caused by a bacterial infection.

Rehabilitation

Rehabilitation is an integral part of treatment and includes:

•       Physical therapy — a personalized exercise program to restore muscle strength.

•       Physical therapy procedures — to improve blood flow and reduce inflammation.

•       Massage — as a supplement to the main treatment.

Important to remember

•       Do not self-medicate—myositis requires an accurate diagnosis and a doctor’s prescription.

•       Seeking timely medical attention and receiving proper treatment significantly improve the prognosis.

•       Follow rehabilitation recommendations—this will speed up recovery.

•       Avoid triggering factors: hypothermia, excessive physical exertion, and stopping medication on your own.

•       Visit your doctor regularly to monitor your condition and adjust your treatment.

Diagnosis and Rehabilitation at Helios

At the Helios Medical Center, we conduct comprehensive diagnostics, monitor the course of the disease, and develop a personalized treatment and rehabilitation program.

An important part of recovery is properly selected physical rehabilitation and therapeutic exercises, which help maintain muscle strength, reduce the risk of atrophy, and improve the patient’s quality of life.

If you experience muscle weakness, pain, or rapid fatigue, it is important to consult a specialist promptly.

Thyroid-Stimulating Hormone (TSH
Thyroid-Stimulating Hormone (TSH

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.
