Why Anemia in Hypothyroidism

What is Anemia?

Anemia is a condition in which the body lacks enough healthy red blood cells. As a result, the body's tissues and organs do not get enough oxygen. This can lead to a variety of symptoms, including fatigue, shortness of breath, and pale skin. Anemia can be caused by a number of factors, including iron deficiency, vitamin B12 deficiency, and chronic diseases like hypothyroidism.

What is Hypothyroidism?

Hypothyroidism is a condition in which the thyroid gland does not produce enough thyroid hormone. Thyroid hormone is essential for a number of bodily functions, including metabolism, growth, and development. When the thyroid gland does not produce enough thyroid hormone, it can lead to a variety of symptoms, including fatigue, weight gain, and constipation.

Link Between Anemia and Hypothyroidism

Anemia is a common complication of hypothyroidism. In fact, up to 50% of people with hypothyroidism will also have anemia. There are several reasons why anemia is so common in people with hypothyroidism.

• Decreased Production of Erythropoietin: Thyroid hormone helps the body produce erythropoietin, a hormone that stimulates the production of red blood cells. When the thyroid gland does not produce enough thyroid hormone, the body produces less erythropoietin, which can lead to anemia.
• Impaired Iron Absorption: Thyroid hormone helps the body absorb iron from food. When the thyroid gland does not produce enough thyroid hormone, the body absorbs less iron, which can lead to iron deficiency anemia.
• Increased Red Blood Cell Destruction: Thyroid hormone helps regulate the lifespan of red blood cells. When the thyroid gland does not produce enough thyroid hormone, red blood cells are destroyed more quickly, which can lead to anemia.

Symptoms of Anemia in Hypothyroidism

The symptoms of anemia in hypothyroidism are similar to the symptoms of anemia caused by other conditions. These symptoms may include:

• Fatigue
• Weakness
• Shortness of breath
• Pale skin
• Cold hands and feet
• Headache
• Dizziness
• Lightheadedness
• Chest pain
• Rapid heartbeat
• Brittle nails
• Hair loss

Diagnosis and Treatment of Anemia in Hypothyroidism

Anemia in hypothyroidism is diagnosed with a blood test. The blood test will measure the levels of red blood cells, hemoglobin, and hematocrit. If the levels of these substances are low, the doctor may diagnose anemia.

The treatment for anemia in hypothyroidism depends on the underlying cause of the anemia. If the anemia is caused by iron deficiency, the doctor may prescribe iron supplements. If the anemia is caused by vitamin B12 deficiency, the doctor may prescribe vitamin B12 supplements. If the anemia is caused by hypothyroidism, the doctor may prescribe thyroid hormone replacement therapy.
