Hypothyroidism is a disease state caused by insufficient production of thyroid hormone through the gland. The most common cause is Hashimoto’s disease, which occurs when the immune system attacks the thyroid gland. The symptoms of hypothyroidism are weight gain, fatigue, increase sensitivity to cold, muscle weakness, bradycardia, puffy face, and so on.
Hyperthyroidism, on the other hand, is the pathologic condition that occurs due to the excessive production of hormones by the thyroid gland. Hyperthyroidism most occurs due to inflammation of the thyroid gland (thyroiditis), autoimmune disease (Grave’s disease), or as a result of a thyroid nodule causing producing too much thyroid hormone.
The symptoms of hyperthyroidism include increased sweating, increased appetite, increased heart rate, sudden weight loss, and increased sensitivity to heat.
There are a lot of people who are not aware of the differences between hyperthyroidism and hypothyroidism. Hyperthyroidism will come with symptoms that are different from hypothyroidism. The usual symptoms of hypothyroidism are slowed metabolism, weight gain, and fatigue. Those who are experiencing hyperthyroidism are going to have different symptoms.
For example, someone who has hyperthyroidism will realize that they are more hyper than before. They will have a lot of energy and they may begin to lose weight without doing anything. Some who have hyperthyroidism may notice that he/she would be sweating too much or will not be able to tolerate heat too much. Someone who experiences weird symptoms should get themselves checked immediately.
