Hyperthyroidism: What It Is, Why It Matters & When to Get Tested

The thyroid is small but powerful. This butterfly-shaped gland in your neck controls metabolism, energy, temperature, and heart rate. When it makes too many hormones, your body speeds up. This condition is called hyperthyroidism.

Many people confuse its symptoms with stress or daily habits. But if ignored, it can lead to serious problems—like heart disease and osteoporosis.

Recognising the Symptoms Early

Hyperthyroidism often starts quietly. You may feel anxious, sweat more, or notice a racing heart. You might lose weight without trying. Trembling hands and sleepless nights are also common.

In some cases, especially with Graves’ disease, your eyes may bulge or your vision may blur.

These signs are easy to miss. You may blame them on stress, caffeine, or lack of rest. However, a thyroid function test is the only way to confirm the real cause.

What Causes an Overactive Thyroid?

Graves’ disease is the leading cause. It’s an autoimmune disorder where the immune system overstimulates the thyroid.

Other causes include thyroid nodules—small lumps that release extra hormones. In some cases, excess iodine from food or supplements can also overstimulate the gland.

No matter the cause, early testing is key. Without treatment, you risk irregular heartbeats, brittle bones, or even a thyroid storm—a rare but severe medical emergency.

How Can You Check Your Thyroid Health?

A simple blood test reveals your thyroid health. At Hi-Tech Diagnostic Centre, we offer a full thyroid panel to detect hyperthyroidism:

T3 & T4 – Measure your total thyroid hormone levels.

FT3 & FT4 – Show active hormone levels your body can use.

TSH – The key marker that often flags thyroid imbalance.

AMA & FTG – Identify autoimmune conditions like Graves’ or Hashimoto’s.

Our fully automated labs ensure fast, reliable results. With this data, your doctor can provide the right treatment.

When Should You Get Tested?

If you feel “off” and can’t explain it, get tested. Sudden weight loss, a racing heart, constant fatigue, or restlessness may signal a thyroid issue.

You can walk into Hi-Tech Diagnostic Centre Palarivattom or any of our 29 branches across Kochi for a quick TSH test.

Don’t wait. Book your thyroid test today at hitechdiagnosticcentre.com and take charge of your health.
