The thyroid is a part of glands that form the endocrine system which coordinates many activities of the body.
The thyroid gland produces hormones that regulate our body’s metabolism. To understand the types of thyroid disorders, it is important to understand two conditions – hyperthyroidism and hypothyroidism.
Hyperthyroidism is when the thyroid gland is overactive and produces a lot of hormones, while hypothyroidism is when the gland is underactive and the production of hormones is not much.
The four common diseases of thyroid are:
This disease happens when the body’s immune system by mistake attacks and destroys the thyroid gland. Because of this, the gland’s ability to produce hormones gets impacted. Hashimoto’s thyroiditis is the most common reason for hypothyroidism. The symptoms of the disorder are fatigue, dry skin, constipation, depression, etc.
The most common cause of hyperthyroidism, Graves’ disease also happens when the immune system out of mistake attacks the thyroid gland, making it overproduce the hormone. The symptoms are somewhat similar to hyperthyroidism such as anxiety, fatigue, irritability, too much sweating, among others.
It is the enlargement of the thyroid gland which is non-cancerous in nature. The most common reason for goiter is a deficiency of iodine in the diet. The symptoms when the enlargement grows big enough include swelling in the neck and voice hoarseness.
They are growths that get formed in or on the thyroid gland. The cause is not always known. Iodine deficiency and Hashimoto’s thyroiditis are probable causes of thyroid nodules. Symptoms of it are somewhat similar to hyperthyroidism like weight loss, tremors, nervousness, among others.
