Thyroid imbalance quietly disrupting your sleep and energy.
Educational information — not medical advice. Talk to your care team about what's right for you.
Thyroid disorders are common, often subtle, and frequently missed as a cause of sleep and energy problems. An underactive thyroid (hypothyroidism) can cause fatigue, cold intolerance, and fragmented sleep, while an overactive thyroid (hyperthyroidism) can cause insomnia, heat intolerance, and a racing heart at night. Because the symptoms overlap with many other conditions, the thyroid is worth checking when sleep and energy are off without a clear explanation.
Dr. Morse treats unexplained sleep and energy problems with a low threshold for checking thyroid function. A simple blood test can identify or rule out a thyroid cause, and effective treatment exists for both under- and overactive thyroid. She is attentive to the subtle presentations — especially in women and post-pregnancy — and she treats the thyroid as one of the first medical conditions to evaluate when sleep and fatigue are chronic and unexplained.
