Is Testing Thyroid Regularly Important

The butterfly-shaped steel serves as the engine of our body and weighs only 25 grams and 2 inches. This is the “thyroid gland,” a small gland located at the base of the neck. It produces two hormones, T3 (triiodothyronine) and T4 (thyroxine), which play a huge role in regulating metabolism and overall functioning of the body. These two hormones are released when another important hormone, TSH, is released by the pituitary gland (the gland located in the brain).

Disorders of T3, T4, and TSH levels can lead to thyroid disorders and disease in the long run. Hypothyroidism occurs when the thyroid gland does not produce enough hormones. Some symptoms include weight gain, lack of energy, and depression. Overproduction of these hormones causes hyperthyroidism. This condition presents with symptoms such as weight loss, restlessness, and tremors.

Blood test

Doctors analyze a person’s symptoms if they suspect a thyroid problem. Blood tests are done to measure levels of T3, T4, TSH, free T3, and free T4. A blood sample is taken from a vein in the arm, placed in a test tube, and sent to a laboratory for analysis.

Result Interpretation

Results of the above-mentioned blood tests are interpreted based on the deviation from standard values.

  • When TSH levels are high and T4 levels are low, hypothyroidism (hypothyroidism) is diagnosed.
  • When the level is low and T4 is high, hyperthyroidism (hyperthyroidism) is diagnosed.
    Mild thyroid insufficiency (asymptomatic hypothyroidism) is diagnosed
  • Also, elevated T3 levels indicate hyperthyroidism, and low T3 levels indicate hypothyroidism.
  • when the level is slightly elevated but the T4 level is still within the normal range.
  • A low TSH with low T4 levels indicates a failure of the pituitary gland or a symptom of a significant non-thyroid illness.

The TSH blood test is the most sensitive indicator of thyroid status. If you are taking medications for thyroid disease, these blood test results will help your doctor fine-tune your treatment options. Patients with pre-existing thyroid should have these blood tests every 34 months as recommended by their doctor.

Do not change your prescribed medications without consulting your doctor. Tame your thyroid gland with this blood test before your metabolism changes and open the door to health catastrophe!
