Causes of hypothyroidism

  • Autoimmune Causes: most common autoimmune disease is Hashimoto’s Thyroiditis. In this condition body develops antibodies against thyroid gland and causes auto-consumption of thyroid. This leads to hypothyroidism.
  • As a response to Hyperthyroid medication: at times over treatment of hyperthyroidism my push the patient towards hypothyroidism, but that’s very easily controlled by tittering the dosage.
  • Radiation therapy: it’s used to treat head & neck cancers even the Thyroid cancer (Radio-Iodine Ablation Therapy) which leads to destruction of thyroid gland and hypothyroidism. Patient would need hormone replacement therapy for life in such conditions.
  • Surgery: if patient has undergone Total Thyroidectomy then they would develop hypothyroidism for life.
  • Drug Induced: few medications alter the thyroid profile of patients. Few of the common drugs are:
    • Amiodarone
    • Interferon alpha
    • Thalidomide
    • Rifampin
    • Lithium
    • Phenytoin
    • Anti-cancer drugs & many more

Less common causes:

  • Low Iodine Intake: patient might be in low Iodine region which might be lead to Goiter. Such cases are less now a days since prevalence of Iodized Salt in diet of population is attaining the minimum requirement of Iodine in people.
  • Pregnancy: due to high demand state or patients develop antibodies towards thyroid leading to hypothyroidism or even post-partum hypothyroidism.
  • Pituitary disorders: pituitary stimulates and regulates thyroid gland so any problem in pituitary would certainly effect the thyroid gland.
  • Congenital conditions:it’s very rare to develop congenital absence or abnormality of thyroid gland. It’s known as Cretinism.

How do we detect hypothyroidism?

The patient has to be thoroughly investigated for the cause:

  • Thyroid function test
  • Thyroglobulin
  • TPO antibody
  • Ultrasonography of neck
  • Fine needle aspiration cytology (FNAC)

What is the treatment?

If all other tests are normal and the patient has Primary Hypothyroidism then levothyroxine is the treatment of choice for patients.

  1. Yes, I do have Hypothyroidism. All the facts and symptoms you’ve shared are so right. I would give this article more weightage as you are a Doctor.

  2. I developed hypothyroidism during pregnancy and have been taking medicine ever since. I do have increased cholesterol levels and sensitivity to cold. Weight gain is also an issue.

      1. My doctor did ask me to get the test once. Since then, I get tested every 3-4 months (TSH levels) and my medicine dose is fine-tuned.

  3. This is really informative. I developed hypothyroidism due to auto-immune disease. Add to that, it runs in the family.

  4. Last year I fell really sick due to stress and untreated jaundice. One thing led to another, and everything in my blood report was on the higher end of the acceptable bracket – including thyroid and diabetes. These articles can be really helpful – thanks,
