Underactive vs. Overactive Thyroid: Why Black Women Are Often Misdiagnosed

Table of Contents
thyroid

Thyroid disorders are among the most common yet least understood chronic health conditions affecting women. For Black women in particular, thyroid disease is frequently missed, misdiagnosed, or dismissed, even when symptoms are disruptive, progressive, and life-altering.

The thyroid—a small, butterfly-shaped gland at the base of the neck—plays a massive role in regulating metabolism, energy, mood, temperature, heart rate, and reproductive health. When it is underactive or overactive, the effects ripple through nearly every system in the body. Yet because symptoms can appear vague, overlapping, or inconsistent, many Black women are told their concerns are “normal,” stress-related, or purely lifestyle-based.

The American Thyroid Association reports that “more than 12 percent of the U.S. population will develop a thyroid condition during their lifetime” and “up to 60 percent of those with thyroid disease are unaware of their condition.” The risk for thyroid complications is even higher in women. A 2021 article in the Journal of the American Medical Association stated that “thyroid dysfunction is more common in women than in men.” 

Understanding the Thyroid’s Role in the Body

The thyroid produces hormones—primarily T3 (triiodothyronine) and T4 (thyroxine)—that help 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
When thyroid hormone levels are too low or too high, the body struggles to maintain balance. Even subtle disruptions can lead to symptoms that affect daily functioning and long-term health.

Hypothyroidism vs. Hyperthyroidism: What’s the Difference?

Although both are thyroid disorders, hypothyroidism and hyperthyroidism are essentially opposite conditions—and are often confused or overlooked.

Hypothyroidism (Underactive Thyroid)

Hypothyroidism occurs when the thyroid does not produce enough hormones. This leads to a general slowing of bodily processes.

Common symptoms include:

  • Fatigue and low energy
  • Weight gain despite no major diet changes
  • Cold intolerance
  • Depression or low mood
  • Dry skin and hair
  • Constipation
  • Brain fog or memory issues
  • Heavy or irregular menstrual cycles
Because these symptoms develop gradually, they are often attributed to aging, stress, or lifestyle—especially in Black women, whose pain and fatigue are routinely normalized or minimized.

Hyperthyroidism (Overactive Thyroid)

Hyperthyroidism is an overactive thyroid condition. The National Institute of Diabetes and Digestive and Kidney Diseases defines it as a condition “when the thyroid gland makes more thyroid hormones than your body needs.” Common symptoms include:
  • Rapid or irregular heartbeat
  • Anxiety or restlessness
  • Unintentional weight loss
  • Heat intolerance
  • Insomnia
  • Tremors
  • Frequent bowel movements
  • Lighter or absent menstrual periods
These symptoms are often misdiagnosed as anxiety disorders, panic attacks, or cardiovascular issues—without proper thyroid testing. Interventions addressing poor thyroid health can range from oral prescription medication to surgical procedures. Hormone replacement therapies are an option in some instances as well. 

Why Symptoms in Black Women Are Often Dismissed

The misdiagnosis of thyroid disorders in Black women is not accidental. It is rooted in medical bias, racialized assumptions, and gaps in clinical research.

Symptom Overlap with “Stress” and “Lifestyle” Labels

Fatigue, weight changes, mood shifts, and sleep problems are frequently attributed to:
  • Stress
  • Depression or anxiety
  • Poor diet
  • Lack of exercise
For Black women, these explanations are often offered prematurely, without adequate testing. The assumption that symptoms are behavioral rather than biological delays diagnosis and treatment.

Weight Bias and Racial Stereotypes

Weight gain—one of the most common symptoms of hypothyroidism—is especially likely to be dismissed in Black women. Instead of investigating hormonal causes, providers may default to:
  • Diet advice
  • Exercise recommendations
  • Moralizing language about “self-care”
This not only delays care but reinforces stigma that discourages patients from returning for follow-up.

Pain and Symptom Minimization

Research consistently shows that Black patients are less likely to have their pain and discomfort taken seriously. Subtle thyroid symptoms—like joint pain, palpitations, or cognitive changes—may be downplayed until the condition becomes severe.

The Impact of Thyroid Disorders on Key Areas of Health

Weight and Metabolism

Thyroid hormones directly influence how the body uses calories. When levels are off, weight changes can occur even with consistent eating and activity patterns. This can be deeply frustrating for patients who are blamed for changes they cannot control.

Mood and Mental Health

Both hypo- and hyperthyroidism can mimic or worsen mental health conditions:
  • Hypothyroidism is associated with depression, low motivation, and brain fog
  • Hyperthyroidism is associated with anxiety, irritability, and panic
Without proper testing, patients may be prescribed psychiatric medications without addressing the underlying hormonal issue.

Fertility and Reproductive Health

Thyroid disorders can interfere with:
  • Ovulation
  • Menstrual regularity
  • Pregnancy outcomes
Undiagnosed thyroid disease increases the risk of infertility, miscarriage, preterm birth, and postpartum complications—yet thyroid testing is not always standard in fertility or prenatal evaluations.

Heart Health

An overactive thyroid can strain the heart, increasing the risk of arrhythmias and high blood pressure. An underactive thyroid can contribute to elevated cholesterol and cardiovascular disease. These risks are especially concerning given existing disparities in Black women’s heart health.

When and How to Advocate for Proper Testing

Because thyroid symptoms are often dismissed, self-advocacy becomes a critical tool—not because patients should have to fight for care, but because the system often requires it.

When to Ask for Thyroid Testing

Consider requesting thyroid testing if you experience:
  • Persistent fatigue that doesn’t improve with rest
  • Unexplained weight changes
  • Mood changes alongside physical symptoms
  • Irregular periods or fertility challenges
  • Heart palpitations or temperature intolerance

What Tests to Request

A comprehensive thyroid evaluation may include:
  • TSH (thyroid-stimulating hormone)
  • Free T4
  • Free T3
  • Thyroid antibodies (to assess autoimmune conditions like Hashimoto’s or Graves’ disease)
Relying on a single TSH test can miss important nuances, especially in early or atypical presentations.

How to Advocate Effectively

  • Document symptoms over time, not just on “bad days”
  • Be specific about functional impact (work, sleep, daily life)
  • Ask directly: “Can we rule out a thyroid issue with labs?”
  • Request copies of lab results and ask for explanations
Advocacy is not confrontation—it is collaboration grounded in informed questions.

Why Awareness Alone Isn’t Enough

Improving thyroid outcomes for Black women requires more than patient education. It demands:
  • Provider training on bias and symptom recognition
  • More inclusive clinical research
  • Standardized screening protocols
  • Accountability when concerns are dismissed
Awareness empowers patients—but systemic change is necessary to reduce the burden of self-advocacy placed on those already navigating chronic symptoms.

Reclaiming Trust in Your Body

Black women are often taught to doubt their bodies—to push through fatigue, ignore discomfort, and accept dysfunction as normal. Thyroid disorders expose the danger of that conditioning.

If something feels off, it deserves investigation. If symptoms persist, they deserve explanation. And if care is delayed or denied, seeking a second opinion is not disloyal—it is lifesaving.

Understanding the difference between an underactive and overactive thyroid is not about self-diagnosis. It is about naming possibilities so that conversations with providers are informed, grounded, and harder to dismiss.
