TSH levels in your bloodstream rise or fall depending on whether there is enough thyroid hormone in your system to meet your bodyâs needs. Higher levels of TSH push the thyroid to produce more hormone. Low TSH levels mean the thyroid is producing more than enough hormone. TSH levels can change a great deal with minor increases and decreases in T4. This is a very tightly regulated feedback process between the pituitary and the thyroid gland.
What do low TSH levels mean? According to About.com, low levels of TSH, or thyroid-stimulating hormone, occur when the pituitary gland shuts down TSH production due to high levels of thyroid hormone in the blood. The low levels of TSH are the pituitary gland's attempt to keep thyroid hormone levels normal within the body. What are some symptoms associated with high TSH levels? According to WebMD, high TSH (thyroid-stimulating hormone) levels indicate an underactive thyroid gland (hypothyroidism). Common symptoms include feeling weak, tired or depressed, sensitivity to cold, constipation, brittle nails, memory problems, and heavy or irregular periods.
