xeno clarification

[Guest guest]

Gael:

You are very clear and you are very kind in sharing. But please do not take

this the wrong way because I have to correct your interpretation. Please

understand that some of your interpretation is correct but not all. It is

really confusing in the words that doctors and researchers use. Truth is when

people use the words " estrogen disruptors " it seems like something will get into

the site and " block " as you say estrogen from getting into the site, but please

understand that is not necessarily the case. In fact most of the time it is not

the case at all. The xenoestrogen mimic estrogen and other hormones, which

means that they go into the receptor for estrogen, (that is not suppose to

happen) " trick " the receptor into letting it in but since it is not estrogen it

can effect more than one hormone, effect the pathways in which estrogen is

utilized and can cause a whole host of problems that are difficult to predict.

If you remember from HS Biology class one receptor for one enzyme, well the body

is only suppose to accept estrogen, but " drugs " and other chemicals are

disrupting the normal estrogen pathway. Maybe even changing the way estrogen is

utilized even when it is true estrogen that binds to the receptors. So no, they

do not really block estrogen from getting in there are millions of receptors on

every cell in your body (that just floors me right there, the human body is

amazing!) estrogen gets in too, and there ya go, the body can perceive too much

estrogen. Actually that is just one of the things that the body can perceive,

there are many more, and some we don't even know about, realize the research is

so new. So if you give estradiol, more estrogen, wow, now you have what the body

makes, the xeno estrogens, the phytoestrogens, (which is why some people should

not eat soy) and you have more estradiol!

But don't believe me, I looked up the research for you.

Abstract

Environmental xenoestrogens can be divided into natural compounds (e.g. from

plants or fungi), and synthetically derived agents including certain drugs,

pesticides and industrial by-products. Dietary exposure comes mainly from

plant-derived phytoestrogens, which are thought to have a number of beneficial

actions. However, high levels of exogenous estrogens including several

well-known synthetic agents are associated with harmful effects. Chemicals like

xenoestrogens, which can mimic endogenous hormones or interfere with endocrine

processes, are collectively called endocrine disruptors. Adverse effects by

endocrine disrupting chemicals (particularly xenoestrogens) include a number of

developmental anomalies in wildlife and humans. Critical periods of urogenital

tract and nervous system development in-utero and during early post-natal life

are especially sensitive to hormonal disruption. Furthermore, damage during this

vulnerable time is generally permanent, whereas in adulthood, ill effects may

sometimes be alleviated if the causative agent is removed. The most commonly

studied mechanism in which xenoestrogens exert their effects is through binding

and activation of estrogen receptors a and similar to endogenous hormone.

However, endocrine disruptors can often affect more than one hormone (sometimes

in opposite directions), or different components of the same endocrine pathway,

therefore making it difficult to predict effects on human health. In addition,

xenoestrogens have the potential to exert tissue specific and nongenomic

actions, which are sensitive to relatively low estrogen concentrations. The true

risk to humans is a controversial issue; to date, little evidence exists for

clear-cut relationships between xenoestrogen exposure and major human health

concerns. However, because of the complexity of their mechanism and potential

for adverse effects, much interest remains in learning how xenoestrogens affect

normal estrogen signaling.

Oh and I have to correct you again, if you deaminate protein, meaning that you

take off the nitrogen from a protein molecule, yes it does turn to glucose

(sugar), and the body will use too much protein as energy which is why the

Atkins diet doesn't really work, but I digress.

At 55 years old I know that you did not go all the way through menopause yet,

but your hormones have been declining for many years before that. I have to

admit, although I don't want to wish my life away, I would rather be dealing

with this at 55 not 45. At 55, bleeding is just not a good sign. I am so sorry

you had to go through that. I am not so sure I agree about progesterone causing

your bought with atypia, the cells of the uterus do not respond to progesterone

like that. In fact high doses of progesterone down regulates estrogen

production. There are some studies that have shown that certain estrogens down

regulate proteins that are found in breast cancer but again we have to be

careful interpreting those studies because those receptors are not the same as

the ones in the uterus. The study I read was a metabolite called 1,7,

Betaestradiol. Is that the drug that they give when the give estradiol. Hmmmm?

The woman was correct, you had a 40 percent chance of it changing to cancer,

which I also thought was not a bad chance either, however in cancer circles that

is way too high!

I was not insinuating that your ovaries are killed after hysterectomy but when

you remove the broad ligament, and other structures with the uterus, many of the

blood vessels to the ovaries are cut, many nerves to the ovaries are cut, heck,

even nerves to the urinary bladder are cut, to the skin... well you get the

picture. Every person is different, different nerve supply and different blood

supply. You had every right to worry, every person that has this done has

different and the same side effects. You are very lucky that your ovaries still

produce hormones, some women's hormones stop immediately, some stop within two

years. No your ovaries do not shrivel up and die, but the uterus also makes

hormones when it is not there the ovaries stop producing the hormones in the

same amounts and sometimes not at all. The studies that show that keeping

ovaries are not that conclusive, but it is great that they are doing these

studies, they are also showing that the right combo of hormones post surgery

will prevent the heart disease, osteoporosis and dementia related to

oophorectomy. Which is probably why you are using the Vivelle dot and are very

happy with it.

Gael, thanks so much for sharing but please understand that in the US, there is

no reason to eat meat, in fact cholesterol only comes from animal products. We

over eat protein in the US, I am not going to get into it at all, but we can get

more than enough nutrition by eating plant products and not have to kill an

animal to do it. I did not have problems with infertility because I am a vegan,

if anything I had problems with infertility because of a lot of stress in my

life and because I was too old. The genetic material in my ova made the eggs

not viable, or it could of been the sperm of my partner, or it could of been my

uterus, where there is a problem to begin with which is what I think but the

doctors said no.
