Hypothyroidism Q & A

What is hypothyroidism?

Hypothyroidism is an underactive thyroid gland that doesn’t produce enough thyroid hormone to meet your body’s needs. The thyroid hormone keeps your body running normally and is used to regulate your metabolic rate, heart function, brain development, muscle control, and much more.

An untreated thyroid issue can cause a number of other health problems like obesity, infertility, joint pain, heart disease, and more.


What are the symptoms of hypothyroidism?

Since the thyroid hormone is used to regulate so many organ systems, hypothyroidism causes a wide range of symptoms, including:

  • Fatigue
  • Extreme weight gain
  • Joint and muscle pain
  • Constipation
  • Dry skin
  • Brittle hair and nails
  • Decreased sweating
  • Insomnia
  • Loss of libido
  • Anemia
  • High Cholesterol

Hypothyroidism develops slowly and symptoms vary a lot between patients. Many of the symptoms are shared with other diseases and are so general that they’re often ignored for years.

If your hypothyroidism progresses to an advanced stage, the health complications will be serious and can lead to premature death. Some of the major organ systems affected by hypothyroidism are your:

Cardiovascular system

Hypothyroidism can slow your pulse and weaken your heartbeat.

Renal system

Low levels of thyroid hormones can affect your kidney function, which affects your body’s ability to get rid of water and absorb salt.

Nervous system

Hypothyroidism can cause muscle weakness and nerve damage.

Reproductive system

Abnormal thyroid levels affect the production of sex hormones, which control the production of sperm and eggs, and affect fertility. The disease can also increase your risk of miscarriage and other birth complications.

If you notice any troubling signs, it’s important to get tested at your yearly physicals regardless of your age.


How do you treat hypothyroidism?

Dr. Sivalingam diagnoses your condition using blood tests that measure the levels of thyroid-stimulating hormone and the hormone thyroxine in your blood. Low levels of these can indicate an underactive thyroid.

If you’re diagnosed with hypothyroidism, Dr. Sivalingam can prescribe synthetic thyroid hormone in the form of an oral medication, which works to restore normal thyroid levels and reverse the symptoms of hypothyroidism. As your condition improves, he adjusts your dosage based on the results of yearly blood tests.

Dr. Sivalingam can also suggest dietary changes to include more fermented foods and foods rich in iodine and zinc to improve your thyroid function.
