Impact of Low TSH Levels.
The impact of low TSH levels is quite widespread on the body ad this is something that is related to the entire body function. In order to understand this impact of low TSH, let’s take a look at the function of thyroid gland and the use of TSH in regulating this function. The thyroid gland is responsible for producing some thyroid hormones, mainly T3 and T4, which are important for the function of various organs in the body.
However, the amount of T3 and T4 to be secreted completely depends upon the body’s requirement and the presence of thyroid hormones in the blood. This requirement is generally estimated by the pituitary gland, which then produces the thyroid stimulating hormone, or TSH, for influencing the thyroid gland into controlling the amount of thyroid hormones in the blood. A low TSH means that the amount of thyroid hormones in the blood is high, and this can be related to a condition of hyperthyroidism.
Symptoms of Low TSH
The symptoms of low TSH are generally related to the condition of excess thyroid hormones in the body, or hyperthyroidism. This is a condition which can bring about certain symptoms in the body. Increased heart rate, anxiety, weight loss etc. are some of the symptoms that can come about due to a low TSH. Weakness, diarrhea, light sensitivity, visual disturbances and tremors in the hands are some extreme symptoms that can arise due to a low TSH level. In order to take care of this condition, you would first have to diagnose the TSH level in the body. Generally, this is done through a simple blood test that evaluates the amount of TSH in the blood. The TSH blood test comprises of the extraction of blood from the upper arm using a surgical needle, and then evaluating it to check the amount of thyroid stimulating hormone in it.
Low TSH Level
The low TSH level is usually estimated to be somewhere around 0.4-4.2mU/L in adults. However, the impact of low TSH is not limited to adults only, and it has widespread implications in children and newborns too. A low TSH is estimated to be 0.7-6.4mU/L in children and 1-39mU/L in newborns. Low TSH levels should not be ignored in any case as they can be seen as a precursor to major health problems.
