Hormone Replacement Therapy Bad, Bioidentical Hormone Replacement Therapy Good

Hormone replacement therapy is often debated within the medical community.  People fail to realize there is a distinct and BIG difference between synthetic hormones and bioidentical hormones.  Studies have shown that hormone replacement therapy using synthetic hormones (Premarin, Prempro, Premphase, Provera, Cycrin, Amen) have actually caused increased risk for disease.

  • 41% increased risk for stroke
  • 29% increase risk for heart attack
  • 26% increase risk for breast cancer
  • 22% increase risk for total cardiovascular disease
  • Shown to double the rate of blood clots
  • Possible contribution to Alzheimer’s disease

Common Side Effects of Using Synthetic Estrogen include:

  • Abdominal swelling
  • Breast tenderness
  • Enlarged breasts
  • Fluid retention
  • Loss of appetite
  • Nausea
  • Sinus irritation and congestion
  • Stomach cramps
  • Weight gain

Common Side Effects of Using Synthetic Progesterone Include:

  • Bloating
  • Blurred vision
  • Breast tenderness
  • Change in vaginal discharge
  • Dizziness
  • Drowsiness
  • Headache
  • Mood swings
  • Nausea
  • Weight gain/loss

Bioidentical hormone replacement therapy (BHRT) uses hormone with the same structure as the hormones created by the body.  BHRT uses progesterone, NOT progestin and estrogens (estriol, estradiol, and estrone) NOT esterified estrogens (dienestrol, ethinyl estradiol, and conjugated equine estrogens).  Studies have shown that BHRT decreases symptoms in menopausal women.  One study revealed that before treatment, 52-70% of the women in the study were experiencing symptoms of hot flashes, night sweats, sleep problems, dry skin/hair, vaginal dryness, foggy thinking, mood swings, and decrease sex drive was decreased.  After treatment with BHRT, only 4-20% were experiencing these symptoms.

Studies have shown that bioidentical progesterone:

  • Increases protection of the cardiovascular system
  • Increases brain function
  • Increases bone density
  • Decreases cancer risk
