Episode 126: Perimenopause or Thyroid Problems? How to Tell the Difference (And Why It Might Be Both)
Are your symptoms perimenopause or thyroid problems?
How to tell whether symptoms are hormonal or thyroid-related? If you’re in your 40s and suddenly dealing with fatigue, brain fog, weight gain, poor sleep, low mood, or feeling unlike yourself, but your blood tests keep coming back “normal,” this episode of The Goode Health Podcast will help you understand what may actually be happening beneath the surface. Nicole Goode explores one of the most common and misunderstood health issues women face in midlife: the overlap between perimenopause and thyroid dysfunction.
In this episode, Nicole breaks down why perimenopause symptoms and hypothyroidism symptoms can look almost identical, how fluctuating hormones can directly affect thyroid function, and why so many women are told their symptoms are “just stress” or “just age.” You’ll learn the key differences between thyroid problems and perimenopause, the symptoms that may point more strongly toward one or the other, and why it’s often not a case of one versus the other, but both happening together.
Nicole also explains what a full thyroid panel should include, why TSH alone may not tell the whole story, and how thyroid antibodies, estrogen fluctuations, progesterone decline, and cortisol all interact inside the body.
This episode answers questions like:
“Perimenopause vs hypothyroidism symptoms”
“Can perimenopause affect thyroid function?”
“Why women in their 40s experience brain fog”
“TSH normal but still symptomatic”
“Hormonal changes during perimenopause”
“Signs your thyroid may be slowing down”
“How hormones and thyroid function affect each other”
Whether you’ve been struggling with unexplained exhaustion, perimenopause weight gain, hormone imbalance, Hashimoto’s symptoms, or ongoing brain fog despite normal labs, this episode will help you better understand your symptoms, recognize important patterns, and advocate for more complete testing and support.

“Perimenopause is not always a gentle decline in hormones the way many women have been led to believe. For many women, it feels more like unpredictability. One week you feel okay, the next week you feel anxious, exhausted, emotional, foggy, or completely disconnected from your body. And when those hormonal fluctuations start interacting with underlying thyroid dysfunction, it can create symptoms that feel impossible to explain unless someone is finally looking at the whole picture together.”
Essential learnings from this episode…
Perimenopause and thyroid dysfunction share many of the same symptoms. Fatigue, brain fog, weight gain, low mood, sleep issues, and hair changes can happen with both hypothyroidism and perimenopause, which is why so many women struggle to get clear answers.
“Normal” thyroid labs do not always mean optimal thyroid health. TSH alone may not reveal the full picture. Free T3, Free T4, thyroid antibodies, and symptom patterns can provide important insight into underlying thyroid dysfunction or Hashimoto’s disease.
Hormones and thyroid function are deeply connected. Fluctuating estrogen, declining progesterone, and elevated cortisol can all directly impact thyroid hormone availability, making perimenopause symptoms and thyroid symptoms worse together.
Symptom patterns can help identify what’s driving your symptoms. Perimenopause symptoms often feel erratic and cycle-related, while hypothyroidism symptoms tend to feel more constant, progressive, and persistent over time.
Tracking symptoms can help you advocate for better care. Keeping a simple symptom log alongside your menstrual cycle can reveal important patterns and help you communicate more clearly with healthcare providers.
Feeling exhausted, foggy, or unlike yourself in your 40s is not “just aging.” Many women are told their symptoms are caused by stress or midlife alone, but underlying hormone imbalance, thyroid dysfunction, or Hashimoto’s may be contributing factors worth investigating further.
