What Causes Hypothyroidism?

Hypothyroidism is a condition in which the thyroid gland is underactive, producing too little thyroid hormone. It can cause a range of symptoms, including tiredness, weight gain, and depression. But what are the underlying causes of this condition, and what can be done to treat it?

What Is Hypothyroidism?

Hypothyroidism occurs when the thyroid gland does not produce enough hormones for the body to function properly. This can leave the body feeling tired, weak, and inactive. It can also interfere with the body’s metabolism and cause weight gain. In more severe cases, hypothyroidism may cause infertility, swelling in the neck, joint pain, and nervous system problems.

What Causes Hypothyroidism?

Common causes of hypothyroidism include:

  • Congenital Hypothyroidism – Congenital hypothyroidism is when an infant is born with the condition. It can be the result of a genetic mutation, or it can be due to a problem with the development of the thyroid gland.
  • Autoimmune Disease – Medical conditions such as Hashimoto’s thyroiditis and Graves’ disease can interfere with the function of the thyroid gland, leading to hypothyroidism.
  • Iodine Deficiency – A lack of iodine in the diet can lead to hypothyroidism. Iodine is an essential mineral, and it plays an important role in the production of thyroid hormones.
  • Radiation Treatment – Radiation treatment for certain types of cancer can cause damage to the thyroid gland, leading to hypothyroidism.
  • Medication – Certain medications, such as lithium and interferon alpha, may interfere with the production of thyroid hormones leading to hypothyroidism.

Treatment for Hypothyroidism

Treatment for hypothyroidism usually involves supplementing the body with thyroid hormones in the form of a daily pill. In more severe cases, surgery may be necessary. It’s important to follow the instructions of the doctor to ensure that the hypothyroidism is effectively treated and managed.
