What is the cause of high TSH levels?
Causes of high TSH levels One of the most common causes of hypothyroidism with a high TSH level is chronic autoimmune thyroiditis, also known as Hashimoto’s thyroiditis. White blood cells begin to attack the thyroid gland, which decreases the amount of thyroid hormone it produces.
Is high TSH harmful?
Slightly elevated TSH levels are usually detected by accident during a routine examination. But taken on their own they don’t pose any health risk.
Does stress cause high TSH?
“Stress increases production of the hormone cortisol, which is produced by the adrenal glands. Cortisol can inhibit secretion of TSH (thyroid stimulating hormone) from the pituitary gland, leading to partial suppression of thyroxine, the main hormone produced by the thyroid gland,” Dr. Guandalini explains.
How do I get my TSH levels down?
If your thyroid is overactive, there are several options:
- Radioactive iodine to slow down your thyroid.
- Anti-thyroid medications to prevent it from overproducing hormones.
- Beta blockers to reduce a rapid heart rate caused by high thyroid levels.
- Surgery to remove the thyroid (this is less common)
Is TSH 25 high?
The typical range of reference for TSH levels is anywhere between 0.45 and 4.5 milliunits per liter (mU/L) . A recent study suggests that the normal range should be more like 0.45 to 4.12 mU/L. TSH can vary wildly based on your age, sex, and stage of life.
What are the causes of increased TSH levels?
Hypothyroidism is one of the most common causes of elevated TSH levels, the National Institute of Diabetes and Digestive and Kidney Disorders explains. The pituitary makes TSH to stimulate the production of thyroid hormones.
What does high TSH levels indicate?
High level of TSH usually indicates that you have an underactive thyroid and that it doesn’t produce enough thyroid hormones. Thyroid-stimulating hormone (TSH) directly affects how much T3 and T4 hormones the thyroid secretes.
What can cause a low TSH level?
Low TSH levels can be caused by pituitary gland tumors, which are almost always benign (not cancerous). If a tumor is detected, you’ll receive hormone or radiation therapy, or have it surgically removed. Cases of low TSH levels due to a pituitary gland disorder are rare.
What are the side effects of high TSH levels?
Abnormally high TSH levels can damage the bones. The levels of calcium in bones may decrease and the person may suffer from osteoporosis (low bone density resulting in brittle bones) and its consequences like frequent fractures. on Heart. High blood TSH levels over an extended period can affect heart health adversely.
