Every January, Thyroid Awareness Month shines a spotlight on a small, butterfly-shaped gland that has a massive impact on your overall health. The thyroid helps regulate metabolism, heart rate, body temperature, mood, weight, and energy levels. When it’s not functioning properly, symptoms can be subtle, confusing, and often mistaken for stress, aging, or lifestyle issues.

At Starling Diagnostics, we see firsthand how undiagnosed thyroid conditions can quietly affect quality of life. This comprehensive guide explains how the thyroid works, common thyroid disorders, warning signs, testing options, and why seeing an endocrinologist is critical for proper diagnosis and long-term management.

At a glance

• The thyroid controls metabolism, energy, heart rate, and hormone balance.
• Millions of Americans have thyroid disease, and up to 60% are undiagnosed.
• Hypothyroidism, hyperthyroidism, thyroid nodules, and thyroid cancer are the most common conditions.
• Symptoms are often vague and overlap with everyday health complaints.
• Blood tests and imaging such as ultrasound are essential for diagnosis.
• Early detection and specialist care can dramatically improve outcomes.

What Is the Thyroid and What Does It Do?

The thyroid gland sits at the front of the neck and produces hormones — primarily T3 (triiodothyronine) and T4 (thyroxine) — that regulate how the body uses energy.

These hormones influence:

• Metabolism and weight regulation
• Heart rate and blood pressure
• Body temperature
• Digestion
• Mood and cognitive function
• Menstrual cycles and fertility

Even small hormone imbalances can affect nearly every organ system.

Why Thyroid Awareness Month Matters

According to the American Thyroid Association, more than 20 million Americans have some form of thyroid disease, and women are 5–8 times more likely than men to be affected. Many people live with symptoms for years before receiving a diagnosis.

Raising awareness helps patients recognize symptoms earlier, seek appropriate testing, and connect with specialists like endocrinologists who focus specifically on hormone health.

Common Thyroid Disorders

1. Hypothyroidism (Underactive Thyroid)

Hypothyroidism occurs when the thyroid does not produce enough hormones. It is often caused by Hashimoto’s thyroiditis, an autoimmune condition.

Common symptoms include:

• Fatigue and low energy
• Weight gain
• Cold sensitivity
• Dry skin and hair loss
• Depression or brain fog
• Constipation

2. Hyperthyroidism (Overactive Thyroid)

Hyperthyroidism happens when the thyroid produces too much hormone, speeding up body functions. A common cause is Graves’ disease.

Symptoms may include:

• Rapid heartbeat or palpitations
• Anxiety or irritability
• Weight loss despite normal eating
• Heat intolerance
• Tremors
• Difficulty sleeping

3. Thyroid Nodules

Thyroid nodules are growths or lumps within the thyroid. Most are benign, but some require further evaluation.

Possible signs:

• A lump in the neck
• Difficulty swallowing
• Hoarseness
• Neck discomfort

Imaging plays a key role in assessing nodules.

4. Thyroid Cancer

While less common, thyroid cancer is one of the most treatable cancers when caught early. Many cases are discovered incidentally during imaging for other reasons.

Who Is at Risk for Thyroid Disease?

You may be at increased risk if you:

• Are female
• Are over age 35
• Have a family history of thyroid disease
• Have autoimmune conditions
• Are pregnant or postpartum
• Have had radiation exposure to the neck
• Have iodine deficiency or excess

Thyroid screening becomes especially important during major life stages such as pregnancy, menopause, and aging.

Symptoms Often Go Unnoticed

One of the biggest challenges with thyroid disease is that symptoms often overlap with common complaints like stress or aging.

Symptoms that should not be ignored include:

• Persistent fatigue
• Unexplained weight changes
• Hair thinning
• Mood changes
• Menstrual irregularities
• Sensitivity to cold or heat
• Changes in heart rate

If these symptoms persist, testing is essential.

How Thyroid Disorders Are Diagnosed

1. Blood Tests

Blood work measures:

• TSH (Thyroid Stimulating Hormone)
• Free T3 and T4
• Thyroid antibodies

These tests help determine whether the thyroid is underactive, overactive, or affected by autoimmune disease.

2. Thyroid Ultrasound

Ultrasound is a non-invasive imaging test used to:

• Evaluate thyroid size and structure
• Detect nodules or cysts
• Guide biopsies when needed

3. Biopsy or Advanced Imaging

If nodules appear suspicious, further testing such as fine-needle aspiration (FNA) or additional imaging may be recommended by your endocrinologist.

Why Seeing an Endocrinologist Matters

While primary care providers often identify thyroid concerns, endocrinologists specialize in hormone-related conditions and are best equipped to manage complex thyroid disorders.

An endocrinologist can:

• Interpret nuanced lab results
• Adjust medications precisely
• Monitor long-term hormone balance
• Evaluate nodules and cancer risk
• Coordinate imaging and follow-up care

At Starling Diagnostics, our endocrinology services are integrated with on-site diagnostic imaging, allowing for faster answers and coordinated care.
