Thyroid

Why have a Thyroid blood test?

One often overlooked yet vital aspect of our well‐being is the thyroid gland. A thyroid blood test is essential for detecting thyroid issues early. This can help prevent and manage fatigue, weight fluctuations, and metabolic issues linked to thyroid dysfunction. It also supports mental and emotional health by identifying imbalances that could cause mood swings, depression, and anxiety. Additionally, regular monitoring aids reproductive health by addressing thyroid-related fertility issues. 

What is the thyroid?

The thyroid is a butterfly-shaped gland in the neck, producing hormones that regulate metabolism, growth, and development, and control energy use, affecting nearly every organ in the body. Therefore it plays a pivotal role in our overall health.

Who may be at risk?

People at risk of suboptimal thyroid function include those with a family history of thyroid disease, women, older adults, individuals with autoimmune diseases, iodine deficiencies, or those who have undergone radiation therapy to the neck.

What are the symptoms?

Symptoms of suboptimal thyroid function include fatigue, weight changes, cold intolerance, hair loss, dry skin, muscle weakness, depression, constipation, memory issues, and irregular menstrual cycles. These can vary depending on whether the thyroid is overactive or underactive.

How does the blood test work?

A thyroid blood test allows for the early detection of thyroid‐related issues. By measuring the levels of thyroid hormones (T3 and T4) and the thyroid‐stimulating hormone (TSH), healthcare professionals can identify any imbalances or abnormalities. Early detection is key to prevent the progression of thyroid disorders, such as hypothyroidism or hyperthyroidism, which can have a significant impact on your overall health and quality of life.

What does my result mean?

Hypothyroidism (under active thyroid) may be indicated by high TSH, low T3 and low T4. Hyperthyroidism (over active thyroid) may be indicated by low TSH, high T3 and high T4. Both conditions affect metabolism and energy levels, but they have opposite effects on the body's functions and require different treatments. Your healthcare professional can provide specific guidance based on your result.

Having a thyroid blood test is a key step in taking control of your health and potentially improving your metabolism, energy levels and fertility.
