What is Hypothyroidism and What Causes It?

Hypothyroidism or also known as underactive thyroid diseases is a condition when the thyroid gland is not producing enough thyroid hormones.
The thyroid gland is located in the lower front part of your neck and the hormones it produces move with the bloodstream and affects almost every part of your body from your heart to your brain, skin and muscles.

The thyroid hormones affect how your body metabolize the energy you are taking from the food you eat, and your metabolism in turn affects your body temperature, heart rate and your energy levels. If you don’t have enough thyroid hormones, your metabolism becomes sluggish and you lack energy.

– What Causes Hypothyroidism?

The main cause for hypothyroidism is a condition known medically as Hashimoto’s thyroiditis which is an inflammation that affects the thyroid gland, thyroiditis is an autoimmune disease that causes the body to produce antibodies that attack and destroy the thyroid gland. Thyroiditis can also be caused by a viral infection.

– Other Causes Of Hypothyroidism:

Radiation Therapy

RadioActive Iodine Treatment
: This Treatment is often orescriped to hyperthyroidism patients who have their thyroid gland over working, however the radiation damage the cells in the gland which leads to hypothyroidism.

Use Of Certain Meds
: Certain Meds like those orescriped for heart problems and psychiatric conditions can affect the production of the thyroid hormones.

Surgeries: Thyroid surgery leads to hypothyroidism if only q part of the gland is removed, the remaining part may still be able to produce enough hormones to meet the body’s requirements.

Iodine Defecienciy: Consuming too little iodine through your diet can lead to hypothyroidism as the gland require iodine to produce hormones, sources of iodine include table salt water, seawater fish, eggs and seaweed.

Pregnancy: The reason is unclear, however many women experience a postpartum hypothyroidism where their thyroid hormones spike so much during pregnancy then drop sharply after child birth, most women regain their regular thyroid function within months of childbirth.

Problems With The Thyroid At Birth: Some babies born with their thyroid gland not completely developed and poorly working, this is called congenital hypothyroidism, most hospitals screen new born babies for this condition.
