If you’ve been feeling tired, foggy, or gaining weight despite eating the same way you always have, your thyroid might be the missing piece. Thyroid issues are extremely common—especially in women—but they’re often overlooked or misdiagnosed. The good news? When treated properly, thyroid imbalance is very manageable and life can feel normal again.
Here’s everything you need to know, without the medical jargon.
What Does the Thyroid Actually Do?
Your thyroid is a small butterfly-shaped gland in your neck that plays a HUGE role in how your body feels every day. It controls:
Metabolism
Energy
Mood
Heart rate
Temperature regulation
Weight stability
When it slows down (hypothyroidism), everything feels sluggish. When it speeds up (hyperthyroidism), everything feels overstimulated. Most people experience the slow version.
Common Signs of an Underactive Thyroid
Constant fatigue
Weight gain or inability to lose weight
Cold hands/feet
Depression or low mood
Dry skin and hair
Hair thinning
Brain fog
Constipation
Slowed heart rate
Heavy or irregular periods
If several of these symptoms sound familiar, your thyroid could be struggling.
Why Does Thyroid Imbalance Happen?
The most common causes include:
Autoimmune conditions (like Hashimoto’s)
The immune system attacks the thyroid.Stress
High cortisol disrupts thyroid hormone conversion.Nutrient deficiencies
Low iodine, selenium, or iron affects thyroid function.Hormone imbalances
Low testosterone or estrogen shifts can impact thyroid signaling.Genetics or chronic illness
Some people are more prone to thyroid issues.
AgeMD evaluates ALL contributing factors—not just TSH.
How AgeMD Tests the Thyroid (More Than Just TSH)
Many clinics only test TSH, which often misses the full picture.
AgeMD checks: - TSH - Free T3 (active thyroid hormone) - Free T4 - Reverse T3 - Thyroid antibodies (for Hashimoto’s) - Cortisol and sex hormones
This allows your provider to understand EXACTLY what’s going wrong
How Thyroid Imbalance is Treated
Thyroid Medication AgeMD uses personalized dosing of: - T4 therapy - T3/T4 combination therapy - Natural desiccated thyroid (when appropriate)
Hormone Balancing Thyroid doesn't work in isolation. Balancing estrogen, progesterone, or testosterone can dramatically improve thyroid symptoms.
Lifestyle & Nutrient Support Simple, doable improvements in sleep, stress, and nutrition can greatly improve thyroid performance.
Key Takeaways
Thyroid imbalance is common and very treatable.
Symptoms often appear years before diagnosis.
Testing must look deeper than just TSH.
AgeMD creates a plan tailored to YOUR thyroid.
