Thyroid Function Test
Thyroid Balance = Life Balance. Check Before Health Goes Off Track Without You Knowing.
Do you feel tired easily? Gained or lost weight unintentionally? Have trouble sleeping, palpitations, or experience chronic hair loss? These symptoms might not just be due to “lack of rest” but could be signs that your thyroid is not functioning properly.
The thyroid is the “control center for metabolism” in the body. If the hormones from the thyroid are too high or too low, the whole body can become unbalanced. A Thyroid Function Test is a crucial check to ensure balance, which should not be overlooked.
What is the Thyroid Gland?
The thyroid gland is a small, butterfly-shaped endocrine gland located at the front of the neck. Its main function is to produce thyroid hormones, which control metabolism and the functioning of organs throughout the body.
Types of Thyroid Hormones:
The thyroid gland produces two main hormones: T3 and T4, and their function is coordinated with a hormone from the pituitary gland called TSH.
TSH (Thyroid Stimulating Hormone)
- Produced by the pituitary gland, TSH stimulates the thyroid to produce T3 and T4.
- If the thyroid is underactive → more TSH is produced to stimulate the thyroid.
- If the thyroid is overactive → TSH levels decrease.
T4 (Thyroxine)
- This is the main hormone produced by the thyroid (up to 90%).
- It is inactive and needs to be converted into T3 before it can be used.
T3 (Triiodothyronine)
- This is the active hormone that controls metabolism, energy, mood, and brain function
- Although in smaller amounts than T4, it is much more potent.
Free T3 / Free T4
- These are “free” hormones that the body can immediately use.
- They are more accurate in assessing thyroid function than the total hormone levels.
Anti-TPO / Anti-Tg
- These antibodies may indicate autoimmune thyroid disease such as:
- Hashimoto’s thyroiditis (hypothyroidism)
- Graves’ disease (hyperthyroidism)
Thyroid-Related Conditions:
Hypothyroidism (Underactive Thyroid):
The body produces insufficient thyroid hormones → metabolism slows down.
Symptoms:
- Fatigue, feeling cold, weight gain
- Dry skin, hair loss, irregular periods
- Depression, slow brain function, forgetfulness
Causes:
- Hashimoto’s (autoimmune destruction of the thyroid)
- Iodine deficiency
- Radiation treatment or thyroid surgery
Hyperthyroidism (Overactive Thyroid):
Symptoms:
- Palpitations, shaking hands, excessive sweating
- Rapid weight loss, excessive hunger but still losing weight
- Irritability, insomnia
- Bulging eyes, irregular periods
Causes:
- Graves’ disease (autoimmune stimulation of the thyroid)
- Thyroid tumors or nodules
What is a Thyroid Function Test?
- A blood test to measure TSH, Free T3, Free T4,
- and potentially Anti-TPO / Anti-Tg to assess autoimmune thyroid conditions.
- This test is useful for diagnosis, monitoring treatment, and overall health assessment.
Why Should You Get a Thyroid Function Test?
- Confirm whether your thyroid is functioning properly.
- Investigate chronic symptoms such as fatigue, difficulty sleeping, weight gain, or hair loss.
- Adjust hormone levels or medication for patients already under treatment.
- Prepare for pregnancy or resolve fertility issues.
- Reduce the risk of heart disease, osteoporosis, or depression.
How to Prepare for the Test:
- No fasting required if only thyroid hormones are being tested.
- Avoid certain medications as advised by your doctor (e.g., thyroid medications, vitamins, or iodine supplements).
- Inform the doctor of any current medications or health conditions.
- Avoid stress or insufficient rest before the test, as this may affect TSH levels.
