What could an analysis with a high tsh possibly mean? What is tsh parsing, then? More information on this topic can be found in this article.
The tsh resolution can fluctuate between being high and low. In this article, we will focus on the meaning and implications of a high tsh resolution:
High tsh analysis and its implications
A blood test called a TSH test reveals the amount of TSH present. More TSH is secreted from the pituitary gland in the brain when thyroid hormone levels in the blood are low, and it is inhibited or less secreted when thyroid hormone levels are high in the blood.
An elevated tsh could indicate the following:
1. Hypothyroidism
The upper limit of the normal TSH ranges between 4-5 mIU/L, and if the result of the TSH analysis is higher than that, this may indicate hypothyroidism. The normal TSH ranges between 0.4 and 4.0 mIU/L, and it may vary from one laboratory to another.
In the case of hypothyroidism, the thyroid gland does not produce enough thyroid hormone, which causes symptoms such as a sluggish metabolism, weight gain, exhaustion, sensitivity to the cold, and others.
2. Subclinical hypothyroidism
It is a condition or an early stage of hypothyroidism, and it gets its name from the fact that, despite the levels of the thyroid hormones T3 and T4 being within the normal range, the tsh test shows a slight over-reaction.
3. Euthyroid Sick Syndrome
As the patients have another disease that causes this problem and are typically in the intensive care unit, the body in this case produces high levels of tsh and low levels of the thyroid hormones T3 and T4 as a result of a problem unrelated to the thyroid gland.
Symptoms associated with elevated TSH
Most frequently, an elevated TSH test indicates hypothyroidism, and in this situation, symptoms that go along with an elevated TSH include:
- Fatigue and physical exhaustion.
- Body weight gain.
- Swelling of the neck and face.
- Cold allergy.
- Dry skin , hair thinning.
- Slowing of the heart rate.
- Irregular menstruation, and its abundance.
- feeling depressed
- constipation .
- Fertility problems.
Factors that may affect tsh levels
In addition to age and sex, there are a number of genetic and intrinsic factors that may influence the analysis of elevated TSH in general and its change, and among these factors are the following:
- Medicines and nutritional supplements.
- Ethnicity.
- The followed diet.
- Iodine status.
- Different time of day, as well as different time of year.
- Autoantibodies, and hydrophilic antibodies.
- Smoking, and various pollutants.
- Other pathological conditions occur at the same time.
