Book your Thyroid function test at a local lab
Could your thyroid be affecting how you feel?
Your thyroid is a small gland that controls your energy, metabolism, and many important body functions. When it’s not working properly, it can affect how you feel day to day.
Thyroid function test details
This thyroid test is a simple blood test that helps check how well your thyroid is working. This test measures your TSH (thyroid-stimulating hormone) level. High or low levels can be a sign of a thyroid problem, such as an underactive or overactive thyroid. Many people don’t realize their symptoms-like fatigue, weight changes, or mood shifts-may be linked to their thyroid.
This test helps you better understand what’s going on in your body so you and your doctor can take the right next steps.

Why TSH levels matter for your well-being
High TSH levels often indicate hypothyroidism, which can cause fatigue, weight gain, depression, and sensitivity to cold.
Low TSH levels are usually linked to hyperthyroidism, leading to symptoms like anxiety, weight loss, and heat intolerance.
Untreated TSH imbalances can increase the risk of heart disease, infertility, and osteoporosis over time.
