- Physiological factors: old age or significant calorie restriction with dieting
- Certain medications: Amiodarone, steroids, beta blockers and synthetic progestins (by the way.... I HATE synthetic hormones)
- Pathological factors: kidney or liver disease, malnutrition, increased cortisol, postop
- Vitamin deficiencies: Zinc, Selenium and Iodine are essential to normal thyroid function.
This is just a very brief overview of hypothyroidism. Many, many textbooks are devoted entirely to the thyroid and its diseases and metabolism. There are so many other things we could cover, but we'll save those for another day! At Sei Bella we wish you all the best Health|Wellness|Beauty!
