Serious symptoms of low TSH, such as high fever, racing heartbeat, confusion, severe agitation, jaundice, or unconsciousness, may If you have hypothyroidism with normal TSH levels, you may still experience symptoms even though your thyroid stimulating hormone (TSH) blood test levels are well within range. Most people whose thyroid works normally have a TSH between 0.4 mU/L and 4.0 mU/L, but there can be variations in "normal" levels and symptoms. A high level of TSH could indicate that your thyroid is underactive.This situation is referred to as primary thyroid disease. As there is a feedback loop between the thyroid and the anterior pituitary, the low amount of thyroid hormones in the blood cause the anterior pituitary to produce more TSH, so that the thyroid would be stimulated to produce more T3 and T4. High TSH is a common health condition that can affect anyone regardless of age, sex, race, or ethnicity. Early signs of high TSH include fatigue, weight gain, sensitivity to cold, and mood changes. Serious symptoms of high TSH, such as confusion, cognitive problems, low body temperature, slow breathing, slow reflexes, slow heart rate, and coma In general, normal TSH levels during pregnancy include: First trimester (9 to 12 weeks): 0.18 - 2.99 (uIU/mL). Second trimester: 0.11 - 3.98 uIU/mL. Third trimester: 0.48 - 4.71 uIU/mL. Always check your lab's reference range on your results report.
