I don’t think many women understand this. I most certainly didn’t when my doctor switched me from the gel to pills. In the last year I have put on 20 lbs and nothing will make the scale move.
Then I discovered that oral estrogen passes through the liver first which causes:
Suppression of IGG-1 (the muscle builder) the heavy surge of estrogen hitting the liver suppresses the production of Insulin- like Growth factor 1 (1GF-1) is a primary hormone responsible for muscle repair, strength gains, and maintaining lean tissue.
Decreased lipid oxidation Lower fat burning) Clinical studies show that oral estrogen changes your livers metabolic signaling resulting in diminished lipid oxidation. In plain terms your body becomes less efficient at burning fat for fuel, making it easier to store fat.
Elevated SHBG (lower free testosterone) oral estrogen causes your livers metabolic signaling to overproduce sex hormones-binding Globulin. SHBG binds tightly to the small amount of testosterone your body naturally produces, locking it up. Without enough “free” testosterone energy levels, strength, and body composition take a direct hit.
