About Dr. Westin Childs

Content: Now, this sounds good, except when you consider this: If conditions are not perfect then your body is just as likely to convert that T4 hormone into the inactive metabolite reverse T3 (3) thereby making your thyroid function WORSE. So what causes your body to convert T4 to T3 and T4 to reverse T3? All of these factors increase T4 to reverse T3 conversion (exactly what you DON'T want): Chronic inflammation or autoimmune disease
Hormone imbalances like insulin resistance and leptin resistance
Nutrient deficiencies (see this post for more info on the 13 nutrients required for proper thyroid hormone function)
Chronic infection (Viral, bacterial or parasitic)
Calorie restricted diets (4) and yo-yo diets
Certain medications: Beta blockers, antihypertensives, anti-seizure medications, diabetic medications, and antidepressants
S,o take a look at that list and ask yourself if you have any of those conditions? You probably have 2 or more if we are just going off of statistics here. The point is this: If you have any of those conditions and you're taking levothyroxine or Synthroid then there is a good chance you might be converting your T4 into reverse T3 instead of T3. ​So let's put this into perspective...
If you're taking levothyroxine or Synthroid (T4 only medication) and your body is turning it into the antithyroid metabolite which can blunt thyroid function (5) it's possible for these medications to lead to weight GAIN instead of weight LOSS.
