159: Hashitoxicosis: When Your Thyroid Swings Too Far | Lizzie Ens

Signs of hyperthyroidism are easy to miss, especially when they show up as heart palpitations, unexplained heat, or exhaustion that will not go away. If your heart has started racing for no clear reason, you feel hot when everyone around you is comfortable, or you wake up from a full night of sleep still tired, an overactive thyroid could be the reason. Hyperthyroidism symptoms get mistaken for anxiety, perimenopause, or plain burnout more often than not, which is almost exactly what happened to Lizzie Ens.

Lizzie Ens, functional nutrition coach, business owner, author, and speaker, walks you through the exact signs of hyperthyroidism she started noticing when her own thyroid swung from subclinical hypothyroidism into hashitoxicosis. Using her real blood work, including a free T3 level of 13 when healthy range tops out around four or five, and her Oura Ring heart rate data, Lizzie breaks down what was actually happening inside her body. You will hear why heart palpitations, feeling hot to the touch, insane nighttime itching, and constant fatigue can all point to an overactive thyroid, plus the theory she has connected it back to something deeper, suppressing your voice. If something in your body feels off and you cannot explain why, this is where you start paying attention.

In this episode, you’ll learn:

• Why heart palpitations that wake you up at night, especially without anxiety, can be one of the clearest signs of hyperthyroidism rather than stress or caffeine.
• How a simple blood panel revealed Lizzie's free T3 level had climbed to 13, more than double the healthy range, and what that number actually means for your metabolism.
• What hashitoxicosis is and why a sudden swing from Hashimoto's antibodies into hyperthyroid territory can happen even years after a hypothyroidism diagnosis.
• Why feeling hot to the touch, insane nighttime itching, and looser stools can all be overactive thyroid symptoms most people never connect to their thyroid at all.
• How to tell the difference between hyperthyroidism fatigue and normal tiredness, including why a full night of sleep can still leave you feeling like you worked out.
• Lizzie's theory that hypothyroidism and Hashimoto's are tied to suppressing your voice, and why finally speaking up may have pushed her thyroid the other direction.
• Why using an Oura Ring to track heart rate and HRV helped Lizzie catch that something was wrong before her symptoms became a bigger problem.
