Handling Iron Deficiency and Hypothyroidism

Handling Iron Deficiency and Hypothyroidism

Jennifer started experiencing frequent bouts of constipation and sluggishness. This interfered with her ability to focus at college or even participate in sports, which she was so fond of. When her concerned mother took her to the doctor, a blood test revealed that Jennifer was suffering from iron deficiency. On further examination, it was discovered that Jennifer’s prevalent iron deficiency had also led to the development of thyroid problems.

We all know that iron deficiency leads to anaemia. Your body cells require sufficient iron supply to produce a protein molecule called haemoglobin. Haemoglobin helps transport oxygen to your cells and tissues so they function well. A low haemoglobin count leaves you vulnerable to disease. What most people don’t know is that iron deficiency also leads to a thyroid disorder called hypothyroidism. Here are some facts on hypothyroidism and how it is linked with iron deficiencies.


Hypothyroidism is a thyroid disorder that is characterised by a slow function of the thyroid gland. Your thyroid gland secretes a hormone that is needed to control and regulate the function of your major organs, including the brain and heart.

Your thyroid also controls the function of your metabolism. Metabolism is the process by which your body converts the food you eat to energy. A slow thyroid gland slows down your metabolism. This explains why people with hypothyroidism suffer from constant exhaustion, weight gain, cold feet, muscle weakness and cramps, joint pains, heavy menstruation, depression, and constipation.

What causes hypothyroidism?

The autoimmune disease Hashimoto’s thyroiditis causes hypothyroidism. This disease is often genetically passed on. However, modern lifestyle and habits including chronic stress, smoking, bad diet, and an irregular sleep cycle can lead to hypothyroidism.

In certain cases, hypothyroidism is also caused by high doses of medication given to reverse the symptoms of an overactive thyroid gland. Hypothyroidism is generally more prevalent among women than men.

How does iron deficiency worsen hypothyroidism?

Iron deficiency slows down the production and conversion of your thyroid hormones. Moreover, iron deficiency leads to physical symptoms which mimic those of hypothyroidism, thus making thyroid problems worse. These symptoms include a slow heart rate, constipation, cold hands and feet, severe hair loss, dizziness, and constant fatigue. Additionally, an iron deficiency also lowers the capability of your immune system to fight disease. This leaves you vulnerable to autoimmune conditions that cause thyroid problems.
