Thyroid is a serious disease, which is called silent killer because its symptoms are very common and are seen slowly. World Thyroid Day is celebrated on 25 May every year to spread awareness about thyroid.
Women are more at risk of thyroid than men. Actually, the thyroid is a gland located in the throat. This gland produces many essential hormones for the body and balances the chemicals. Usually thyroid disease is genetic but due to wrong diet and wrong lifestyle, this disease can make you a victim. There are 2 types of thyroid disorder -hypothyroidism and hyperthyroidism.
Research so far has found that 4 to 10 percent of the total population of any country has hypothyroidism and only 1 percent have hyperthyroidism. Both these situations are harmful for health.This problem bothers women more than men.
There are some differences in the symptoms of both these types of thyroid. Let us tell you what are these differences.
In hypothyroidism, thyroid gland starts to work slowly and it is not able to produce the hormones T3, T4 required by the body, but the level of TSH in the body increases.
Symptoms of hypothyroidism
- Weight gain, fatigue, irritability, depression
- Dry skin, brittle nails
- Cold intolerance
- Joint and muscle pain
- Lack of sweat
- Hair fall
- Heavy or irregular menstruation and impaired reproduction
- Decreased heart rate
Causes of hypothyroidism
- Medicines such as lithium carbonate
- Lack of iodine in the body
- Genetic reasons
- Pituitary gland and hypothalamus disturbances
- Because of viral and bacterial infections
In hyperthyroidism, the thyroid gland becomes very active. Due to this, T3 and T4 hormone is released in excess and becomes soluble in blood and TSH levels are reduced.
Symptoms of hyperthyroidism
- Feeling nervous, moody, weak or tired
- Excessive sweating, feeling hot
- Problems with breathing, increased heart rate, trembling hands
- Hair loss problem
- Rapid weight loss even after consuming enough food
- Short menstruation
- Skin itching and redness
- Soft nails
Causes of hyperthyroidism
- Graves’ disease is a major cause of hyperthyroidism. In this, the secretion of thyroid hormone from the thyroid gland is greatly increased.
- Vanine (noncancerous) thyroid tumor, which removes an increased amount of thyroid hormone in an uncontrolled manner.
- Toxic multinodular goiter, a condition that causes the thyroid gland to become enlarged due to multiple vinine (noncancerous) thyroid tumors and increases the amount of thyroid hormone secretion.
What is the difference between hypothyroidism & hyperthyroidism?
In hyperthyroidism there is an increase in thyroid hormone levels while in hypothyroidism there is a decrease in thyroid hormone levels.
Hyperthyroidism can be thyrotoxicosis and Graves’ disease. Whereas hypothyroidism does not produce these diseases.
Hyperthyroidism has a rapid metabolism, while hypothyroidism slows metabolism.
Hypothyroidism is treated by thyroid hormone supplements, while in hyperthyroidism is treated with anti-thyroid drugs.
