Hyperthyroidism is a condition where there is an overproduction of , which play a significant role in the smooth functioning of various critical processes of the . Let’s more about these hormones and their connection to .
What is Hyperthyroidism?
Hyperthyroidism refers to the state of overactivity of the thyroid in the body. It is a condition in which the thyroid gland, that is shaped like a butterfly, produces excess thyroid hormones and is also sometimes referred to as thyrotoxicosis. The thyroid gland produces tri-iodothyronine (T3) and thyroxine (T4) hormones which regulate our metabolism. The pituitary gland in the regulates the production of these hormones by secreting a chemical called thyroid stimulating hormone (TSH). These hormones keep the body and ensure and .
The causes of hyperthyroidism include:
- Graves’ disease: Graves’ disease and is the most commonly found reason for hyperthyroidism. It is characterized by the retraction of upper along with and erythema. Graves’ disease is caused by the release of excess thyroid hormone by the thyroid gland. This happens because of the present in the , stick to particular activating on the gland, which triggers the growth of thyroid gland resulting in excess secretion. is an
- Toxic nodular goiter: Another reason for hyperthyroidism to occur is the gradual growth of lumps or nodules in the thyroid gland. These lumps lose their regulatory mechanism and boost the of thyroid gland resulting in excess secretion of the thyroid hormone into the blood. It is also known as multinodular .
- Immune system malfunction: Some viral in the thyroid or system may also be a cause of hyperthyroidism. This condition also known as thyroiditis can cause leakage of stored thyroid hormone by the gland.
- Excess of iodine: iodine intentionally or inadvertently from various sources such as and X-ray contrast mediums can also lead to hyperthyroidism in vulnerable individuals. of excess
Thyroid hits moreas compared to and typically happens after 60 years. Let’s see some of the other signs and :
- Increased metabolism: Thyroid hormones contribute significantly to the rate of the processes in the body. Excess thyroid hormone has a tendency to accelerate the functions of the body. metabolism as a result of hyperthyroidism may primarily lead to an over-energized body. However, eventually, the body breaks down with the persisting hyperthyroidism leading to general body and .
- Goiter: Due to the enlarged thyroid gland, from Graves’ disease may experience swelling in front of the neckline also known as ‘goiter’. Some may have raised upper eyelids making their look enlarged and protruding.
Individuals suffering from hyperthyroidism might also experience other symptoms such as:
- Weakness in the upper and

The following are the ways tohyperthyroidism:
- Physical tests: Diagnosis of hyperthyroidism can be done by conducting a simple physical test generally detecting an enlarged thyroid gland and fast running . The patient might exhibit rapid reflexes and as already stated, some abnormality in the eyes in case of Graves’ disease.
- Lab tests: The would also conduct lab test to confirm the level of tri-iodothyronine (T3), thyroxine (T4) and TSH. Tests conducted on an over-active thyroid gland normally result in low level of TSH and high level of thyroid hormone in the .
- Scanning: In addition, the physician might also conduct a thyroid scan to reveal the basic cause and necessary details.
Difference between Hyperthyroidism & Hypothyroidism
Hypothyroidism refers to an underactive thyroid, whereas hyperthyroidism refers to an overactive thyroid. Both these conditions have opposite effects on the body – while causes depression, weight gain, and tiredness; hyperthyroidism causes , increased , and weight loss.
Hypothyroidism: Here, the thyroid gland slows down the production of hormones and thereby results in slowing down the metabolism. Hypothyroidism is mostly caused by a condition called Hashimoto’s disease, in which the body starts attacking its own immune system. This prevents the production of hormones by the thyroid gland.
Hyperthyroidism: Here, the thyroid gland increases the production of hormone and thereby results in an overproduction of the hormones. This causes an increase in the metabolism. Hyperthyroidism can most commonly be seen in the form of Grave’s disease that causes goiter and inflammation of the eyes.
