Thyroglobulin

What's

Thyroglobulin (Tg) is a protein made by your thyroid gland, the small, butterfly-shaped organ in your neck. This protein is essential for creating thyroid hormones, which are important for managing your body's metabolism. Tg acts like a storage container, holding onto iodine - a necessary ingredient your body uses to make thyroid hormones. When your body needs more thyroid hormones, Tg releases the stored iodine for hormone production. In short, Tg is a vital part of your body's metabolic system, helping to maintain your energy levels and keep your body working effectively.

If Your Levels Are High

Elevated Thyroglobulin (Tg) levels might mean that your thyroid gland is working extra hard. This can happen for various reasons, such as your body needing more thyroid hormones, changes in your diet, or taking certain medications like lithium or iodine-containing drugs. High Tg levels could also point to a problem with your thyroid gland itself, like inflammation or an autoimmune issue where your body's defense system accidentally attacks your own cells. Keep in mind that these are just possible explanations and not definite conclusions.

Symptoms of High Levels

Symptoms of high levels of Tg could include fatigue, unexplained weight gain, dry skin, hair loss, sensitivity to cold, and muscle weakness.

If Your Levels are Low

Low levels of Tg might mean that your thyroid gland isn't working as well as it should. This could be due to a number of reasons, such as not getting enough iodine in your diet, which is crucial for making Tg and thyroid hormones. Some medications, like those used to treat overactive thyroid, could also lower Tg levels. Additionally, conditions like Hashimoto's thyroiditis, where your immune system attacks your thyroid, might be a factor. It's worth noting that things like stress and poor diet can also impact how well your thyroid functions.

Symptoms of Low Levels

Symptoms of low levels of Tg might include fatigue, unexplained weight gain, dry skin, hair loss, and sensitivity to cold.
