Hypothyroidism 101

Hypothyroidism or low thyroid function affects 5% of the total population but up to 15% of women. The incidence increases with age.

• Fatigue, low energy (99%)
• Weight Gain
• Gets cold easily (89%)
• Dry or coarse skin (89%)
• Constipation (61%)
• Hair Loss
• Forgetfullness (61%)
• Irregular menses
• Elevated cholesterol

The above is not a complete list and as you may notice, the symptoms are not very specific because they could be caused by other health issues.

Because of this, lab tests are usually done to prove or disprove the the diagnosis of hypothyroidism.

• TSH (Thyroid Stimulating Hormone). Higher levels of TSH indicates decreased thyroid function. What is normal TSH?
• T4 is the less active form of thyroid hormone. Medications like Levothyroxine and Synthroid are forms of T4.
• T3 is the more active form of thyroid hormone. Medicatons like Cytomel are T3. 
• T4 is converted into T3 primarily in the liver, but also in the kidneys.  The co-factors for converting T4 to T3 include the nutrient selenium and iron.

Hypothyroidism is usually treated with thyroid hormone replacement.  Optiions include:

• T4=Synthroid, Levothyroxine
• T3=Cytomel
• Combination T4/T3= Armour, Nature-Throid
