The thyroid is located at the front of the neck, situated below the cartilage known as the Adam's apple. It is a small, butterfly-shaped gland responsible for the production of thyroxine (T-4) and triiodothyronine (T-3) hormones that regulate the body's metabolic rate and development. An imbalance in thyroid hormones can adversely affect the functioning of various organs and systems in the body.

What are the Symptoms of Thyroid Problems and How are They Treated?

Thyroid problems arise from the underactivity or overactivity of the thyroid gland and affect many of the body's systems. These issues are generally categorized into two main groups: hypothyroidism (insufficient hormone production) and hyperthyroidism (excessive hormone production). The symptoms of both conditions vary greatly and need to be monitored closely.

In hypothyroidism, the metabolism slows down, leading to symptoms such as persistent fatigue, weakness, weight gain, intolerance to cold, constipation, difficulty concentrating, depressive mood, menstrual irregularities, hair loss, and dry skin. Hypothyroidism often begins insidiously and may go unnoticed for a long time. It is more likely to occur in women, especially in the postpartum period.

Hyperthyroidism, on the other hand, causes the metabolism to speed up. In this condition, symptoms such as sudden weight loss, palpitations, sweating, irritability, insomnia, tremors, hair thinning, hot flashes, and sometimes prominence of the eyes are observed. Hyperthyroidism can seriously impact quality of life and lead to complications like heart rhythm disorders.

Thyroid issues are diagnosed with blood tests (TSH, T3, T4), thyroid antibodies, ultrasound, and biopsy, if necessary. Treatment varies depending on the type of thyroid disease. Levothyroxine-based thyroid hormone medications are typically used in hypothyroidism. These medications should be taken regularly and on an empty stomach. In hyperthyroidism, medication treatment, radioactive iodine, or surgical options may be considered.

In both cases, treatment should be individually tailored and monitored with regular doctor check-ups. Additionally, lifestyle factors such as nutrition, sleep, and stress management can directly impact the success of the treatment. Therefore, individuals with thyroid problems should not only focus on medical treatment but also pay attention to their lifestyle habits.

What are the Symptoms of Thyroid Diseases?

Dysfunction in the thyroid gland can lead to various physical and emotional symptoms. Underactive or overactive thyroid results in adverse effects on the body, and these symptoms can vary from person to person. To make an accurate diagnosis, consulting a doctor is essential.

  • Weight gain
  • Palpitations
  • Anxiety
  • Restlessness
  • Hair loss
  • Voice changes
  • Lump in the neck
  • Swelling in the neck
  • Menstrual irregularity
  • Constipation
  • Muscle pain
  • Joint pain


High Thyroid: Hyperthyroidism  Hyperthyroidism develops due to the excessive production of thyroid hormones and accelerates metabolism.
Low Thyroid: Hypothyroidism  Hypothyroidism results from insufficient hormone production by the thyroid gland, leading to a slowing of metabolism.

How is Thyroid Disease Treated?

Treatment of thyroid disease varies based on the type and severity of the disease. Overactive or underactive thyroid requires different treatment approaches. During the treatment process, doctors regularly check patients' hormone levels and adjust medication dosages accordingly. If medication treatment is not sufficient, surgical intervention is usually a recommended option. If you have a thyroid issue, it is important to see a doctor for early diagnosis and treatment. Early diagnosis allows thyroid gland diseases to be treated without the need for surgical intervention.

Frequently Asked Questions

What is Thyroid Disease?

The question, "What is thyroid disease?" is used to define health issues involving structural or functional disorders of the thyroid gland located at the front of the neck. The thyroid gland produces thyroid hormones (T3 and T4) that regulate the body's metabolic rate. An imbalance in the secretion of these hormones can lead to health problems that affect many systems. Structural disorders such as nodules or enlargement (goiter) in the thyroid gland are also included under thyroid diseases.

Thyroid disorders can directly affect body weight balance, mood, digestive system, heart rate, and menstrual regularity over time. Therefore, symptoms should not be underestimated, and regular hormone tests should be conducted. Thyroid diseases are more commonly seen in women than in men and can become more pronounced during hormonal transitions such as reproductive periods, pregnancy, and menopause.

What are the Symptoms of Thyroid Disease?

The symptoms of thyroid disease vary depending on whether the thyroid gland is overactive (hyperthyroidism) or underactive (hypothyroidism).

Symptoms of hypothyroidism include persistent fatigue, weakness, weight gain, sensitivity to cold, constipation, dry skin, hair loss, slow heart rate, depression, and forgetfulness. The slowing of metabolism can lead to decreased energy and disruptions in daily activities.

In contrast, symptoms of hyperthyroidism include weight loss, palpitations, excessive sweating, hand tremors, insomnia, irritability, increased appetite, and hair thinning. In some individuals, protrusion of the eyes may also occur.

If these symptoms persist for a long time, detailed evaluation using thyroid hormone tests (TSH, T3, T4) and ultrasound is necessary. Early diagnosis helps prevent progressing systemic complications.

Which Department Treats Thyroid Disease?

The question "Which department treats thyroid disease?" is the first topic many people research when experiencing these symptoms. The following medical specialties are usually involved in the diagnosis and follow-up of thyroid diseases:

Endocrinology and Metabolism specialists identify overactive or underactive thyroid hormone conditions and plan appropriate treatments. This department particularly handles medication dose adjustments, autoimmune thyroid diseases, and long-term follow-ups.

Internal Medicine (General Medicine) is often the first point of consultation. After an initial assessment, patients may be referred to endocrinology if necessary.

General Surgery comes into play in cases such as nodules, goiter, or thyroid cancer, planning surgical interventions. Therefore, it is very important for individuals with thyroid disease to be followed up under expert physician supervision with proper guidance.

How Should Nutrition be Managed in Thyroid Gland Diseases?

The question "How should diet be managed in thyroid gland diseases?" is crucial for supporting the treatment of both hypothyroidism and hyperthyroidism patients. Dietary habits directly affect the release of thyroid hormones.

Hypothyroidism patients should follow a balanced diet rich in minerals like iodine, selenium, and zinc. Foods such as seafood, eggs, whole grains, and leafy greens are effective in meeting these needs. It is also recommended that consumption of coffee, dairy products, and soy-containing foods occurs at least 30 minutes after taking thyroid medication.

A gluten-free diet may positively impact the immune system, especially in autoimmune-based hypothyroidism cases such as Hashimoto's thyroiditis.

In hyperthyroidism patients, iodine intake should be limited, and caffeine and alcohol consumption should be controlled. Calcium and vitamin D supplementation is essential for protecting bone health in these patients. The diet must be individually planned and regularly reviewed by a dietician or endocrinologist.

What is the Importance of Early Diagnosis in Thyroid Diseases?

Thyroid diseases can cause serious complications if not diagnosed early, as they affect many systems. Secondary health issues such as heart rhythm disorders, infertility, high cholesterol, muscle weakness, nervous system disorders, and depression can develop.

Early diagnosis allows control of thyroid hormone levels, preventing organ damage. Hormone tests like TSH, free T3, and T4 are the first steps in evaluating thyroid function. Along with these tests, ultrasound is used to detect structural abnormalities such as thyroid nodules or gland enlargement. If necessary, advanced tests like biopsy and thyroid scintigraphy are utilized.

Starting appropriate treatment with early diagnosis improves the individual’s quality of life, with symptoms like fatigue, mood swings, and concentration issues rapidly diminishing. Regular monitoring and ensuring thyroid functions are particularly beneficial for women undergoing infertility treatment, as it can positively affect pregnancy success. Therefore, it is necessary to pay attention to symptoms without underestimating them and monitor thyroid functions with regular check-ups.
