Feeling out of sync? A quick blood test checks your thyroid hormones(TSH & T4). High or low levels could explain unexplained fatigue or weight gain.
Here are some reasons why you may have a thyroid hormone imbalance:
If you are having weight issues, mood changes, excessive sweating or feeling tired all the time this may indicate a thyroid problem. The thyroid is a small butterfly-shaped gland in the neck that produces hormones crucial for regulating metabolism and maintaining overall health. Abnormal results may indicate various thyroid disorders, including:
This thyroid test will enable a more personalized management plan based on your specific result. Identifying problems early is beneficial in managing potential thyroid issues.
Thyroxine (T4), one of the thyroid hormones produced by the thyroid gland, plays a crucial role in accelerating metabolism. The majority of T4 is typically bound to carrier proteins in the blood. This test measures the free, or unbound, T4, which is the active form in the body. When free T4 levels are too low, it may result in symptoms such as fatigue, weight gain, and intolerance to cold, reflecting a potential underactive thyroid (hypothyroidism). Conversely, elevated levels of free T4 may lead to symptoms such as weight loss, nervousness, and heat intolerance, indicating a potential overactive thyroid (hyperthyroidism). Free T4, being the less active of the two primary thyroid hormones, requires conversion to a more active form when needed to exert its effects on cells. Maintaining an appropriate balance is crucial for overall thyroid function and well-being
Thyroid Stimulating Hormone (TSH) is manufactured in the pituitary gland to regulate the thyroid gland's production of thyroid hormones, thyroxine (T4) and triiodothyronine (T3). When the levels of thyroid hormones in the blood are low, increased TSH production stimulates the thyroid gland to produce more. Conversely, elevated thyroid hormone levels prompt the pituitary to reduce TSH production, slowing down thyroid hormone production. Abnormal TSH levels, whether too high or too low, often indicate an issue with the thyroid gland, leading to either underproduction or overproduction of thyroid hormones. Occasionally, disruptions in the pituitary gland can also result in irregular TSH levels.
