Have you ever been told your exhaustion is just part of being a working adult, a mom, or a high achiever? I’ve been there too. That’s why I was so happy to speak with my dear friend, Dr. Alex Carrasco, about one of the most overlooked and misunderstood symptoms people with thyroid conditions face: fatigue.
Dr. Alex Carrasco is a board-certified functional medicine physician, bestselling author of Bloom: Seven Steps to Reclaim Your Health, Cultivate Your Desires, and Reignite Your Spark, and founder of Nourish Medicine. With over a decade of functional medicine experience, Dr. Alex has spent over a decade helping people get to the root of their chronic fatigue, brain fog, and burnout — and she’s here to share her most powerful tools with us.
In this episode, we dive deep into what’s really driving fatigue — beyond just thyroid hormone levels — and how Dr. Alex helps her patients reclaim their energy and vitality. We discussed the testing that often gets missed, the nutrients you didn’t know you needed, and why lifting weights and going outside might be more powerful than your morning coffee.
What you’ll learn in this episode:
- Why fatigue is rarely caused by just one thing and how to uncover all the hidden “logs” in your bonfire. Dr. Carrasco shares her metaphor of fatigue as a bonfire fueled by many logs — like nutrient deficiencies, hormone imbalances, chronic infections, and emotional stress — and how removing them one by one can lead to real healing.
- The critical nutrient deficiencies that can mimic thyroid issues (it’s not just B12!). Low levels of thiamine, ferritin, vitamin D, and CoQ10 can all contribute to fatigue, brain fog, and other symptoms that are often misattributed to thyroid dysfunction alone.
- The sleep mistake almost everyone makes — and how a simple circadian reset can help. Unfiltered morning sunlight and limiting blue light at night can dramatically improve sleep quality and energy levels throughout the day.
- The genetic blueprint that could explain your symptoms (plus what foods can help!). Polymorphisms like MTHFR and COMT can impact how your body handles nutrients, stress, and neurotransmitters, and knowing your genetic tendencies can help you eat and supplement smarter.
- The overlooked environmental factor that might be hiding in your home, office… or car. Mold exposure can suppress the immune system, drain your energy, and even impact mood and cognition.
