36
What are all the gynecological conditions associated with estrogen DOMINANCE (hyper-estrogenism). (4)
- PMS - Abnormal uterine bleeding - Benign growths of breast, uterus, ovary - Breast cancer risk
37
What causes estro dominance? (5)
Increased body fat (estrogen production) Poorly functioning liver (estrogen catabolism) Lack of nutrient cofactors required for estrogen metab Inefficiency elim of estrogen metabolites Also, insufficient progesterone production can oppose effects of estrogen
38
What gyn conditions are estrogen deficiency?
Menopause Amenorrhea Some types of infertility
39
What gyn conditions are better described as eicosanoids imbalance?
Dysmenorrhea Pain is from combo of eicosanoids-mediated ischemia, uterine mm irritability, and nerve hypersensitivity.
40
What is a natural therapy strategy to regulate estrogen?
Anything that helps liver function - reduce dietary fat - increase fiber and plant food - improve colon bacteria - adequate micronutrient intake
41
How does reducing dietary fat help regulate estrogen?
Animal fat contains arachidonic acid which is a precursor of leuteolytic prostaglandin
42
How does increasing dietary fiber and plant food help regulate estrogen?
Decreases enterohepatic recycling of estrogen and decreases plasma estrogen levels which increases fecal excretion of estrogen
43
How does healthy colon bacteria help regulate estrogen?
Improve intestinal elimination of estrogen w/ Lactobacillus acidophilus cultures, which inhibit fecal bacteria and deconjugate estrogen and render it available for absorption back into circulation
44
What are 4 ways to help liver function?
- reduce dietary fat - increase fiber and plant food - improve colon bacteria - adequate micronutrient intake
45
How is estrogen metabolism affected by liver function and the intestinal environment?
Ovary makes estradiol Estradiol converted to estrone and then estriol in the liver. Estrogen dominance may be because of 1 - incomplete conversion which leads to a build up of estradiol Estradiol contributes to fibrocystic breast disease, dysfunctional uterine bleeding, breast cancer, endometriosis, PMS.
