A TSH level above the normal range may indicate hypothyroidism, where thyroid hormone levels are too low. This could be due to impaired thyroid function caused by autoimmune diseases, thyroid surgery, radioactive iodine treatment, or other factors.
TSH levels are elevated, but FT4 and FT3 levels remain within normal limits. This condition may require regular monitoring to assess the progression of hypothyroidism.
High TSH levels may occur due to increased feedback regulation by the pituitary gland or hypothalamus, leading to increased TSH secretion.
TSH levels are elevated, but thyroid hormone levels are normal or low, possibly due to reduced response to thyroid hormones in the body.
Certain medications, such as antidepressants, beta-blockers, and others, may affect TSH levels.
TSH levels may increase during pregnancy, especially in the first trimester.
TSH levels may increase with age, and women may experience variations in TSH levels during different stages of their menstrual cycle.
