Thyroid disease
The thyroid is a small but crucial gland located in the neck, responsible for regulating metabolism, energy production, and body temperature. Disorders of the thyroid, such as hypothyroidism (underactive thyroid), hyperthyroidism (overactive thyroid), and thyroid nodules or cancer, can affect your overall health. Early diagnosis and treatment are key to managing thyroid conditions and ensuring optimal well-being.
When to worry?
- Unexplained Weight Changes
- Fatigue or Weakness
- Neck Swelling or Lumps
- Mood Swings and Depression
- Changes in Heart Rate
Risk factors
- Family History: A family history of thyroid problems increases the risk of developing thyroid diseases. Genetic predisposition plays a significant role, especially in conditions like Hashimoto’s thyroiditis or Graves’ disease.
- Age and Gender: Women, particularly those aged 20 to 60, are more likely to develop thyroid issues, especially autoimmune thyroid disorders like hypothyroidism. Men can also develop thyroid disorders but at a lower rate.
- Pregnancy and Postpartum: Hormonal changes during pregnancy and after childbirth can trigger thyroid problems, particularly postpartum thyroiditis.
- Autoimmune Disorders: People with autoimmune diseases, such as rheumatoid arthritis or type 1 diabetes, are at higher risk of developing thyroid diseases.
- Iodine Deficiency: A lack of iodine in the diet can lead to thyroid dysfunction, as iodine is necessary for thyroid hormone production.
Diagnosis
- History & Clinical examination
- Blood Tests
- Imaging Tests
- Biopsy
Treatment
-
Hypothyroidism (Underactive Thyroid) :
Levothyroxine, a synthetic thyroid hormone, is commonly prescribed to replace the missing thyroid hormone. -
Hyperthyroidism (Overactive Thyroid):
Antithyroid medications, such as methimazole, can help reduce thyroid hormone production. -
Radioactive Iodine Therapy:
Often used for hyperthyroidism or thyroid cancer, radioactive iodine can help shrink overactive thyroid tissue or destroy cancer cells. This is a common treatment for Graves' disease and toxic goiters. -
Thyroid Hormone Replacement:
For hypothyroidism patients, long-term thyroid hormone replacement is often necessary to maintain normal thyroid function. This typically involves daily medication with regular monitoring of hormone levels.
