The thyroid is a butterfly-shaped gland in your neck. It is responsible for producing the hormone thyroxine (also known as T4), which helps regulate metabolism, body temperature, and the proper functioning of many other organs including the brain and heart. Hypothyroidism occurs when thyroxine production does not meet the normal threshold.
Causes of Hypothyroidism
Causes of hypothyroidism include various autoimmune disorders like Hashimoto’s thyroiditis, past thyroid surgery, past thyroid radiation, and low levels of dietary iodine.
The 6 Most Common Symptoms
1) Fatigue
Low thyroid hormone production leads to lower energy levels. Patients who have hypothyroidism may find themselves tiring more easily.
2) Weight Gain
A lack of thyroxine results in slow metabolism, which can cause weight gain.
3) Dry Skin
Itchy skin, cracked skin, or a flaky scalp can be symptoms of hypothyroidism.
4) Depression
Changes in thyroxine hormone levels may negatively impact one’s mood.
5) Constipation
A thyroxine insufficiency can slow down many of your body’s normal functions, including bowel movements. This may cause constipation.
6) Feeling Cold
As hypothyroidism slows metabolism, your body burns fewer calories and therefore may have a lower core temperature. Thus, hypothyroidism can cause an increased sensitivity to the cold.
Diagnosis & Treatment
Hypothyroidism can be diagnosed through a simple blood test. The blood test will evaluate the levels of thyroxine in your system. Hypothyroidism can be completely controlled with hormone supplementation. If you are concerned about hypothyroidism, talk to your doctor.
