About Thyroid-Stimulating Hormone
TSH regulates thyroid function, affecting metabolism, energy levels, and overall endocrine balance.
The reasons for low TSH
Low TSH is usually a sign of hyperthyroidism due to Graves’ disease, excessive iodine intake, or overuse of thyroid medication. Treating the underlying cause and adjusting iodine intake can help restore balance.
The reasons for elevated TSH
High TSH levels suggest hypothyroidism, which may be caused by Hashimoto’s thyroiditis, iodine deficiency, or thyroid dysfunction. Increasing iodine intake, addressing autoimmunity, and using thyroid hormone replacement therapy can help regulate TSH levels.
Is it bad too have too high/low TSH?
Low TSH leads to excess thyroid hormone production, which can cause rapid heartbeat, anxiety, unintended weight loss, and difficulty sleeping.
High TSH results in reduced thyroid function, leading to fatigue, weight gain, depression, slowed metabolism, and sensitivity to cold.
