PROGESTERONE & Estrogen Dominance - some useful snippets in this relating to Thyroid


Progesterone Cream helps stop hair thinning and hair loss due to Estrogen Dominance. Estrogen Dominance (too much estrogen) causes hair loss. So avoiding xenoestrogens and phytoestrogens and taking progesterone cream can help hair loss problems. Too much estrogen tells the body to build up fat and have weight gain for the pregnancy. Weight loss becomes impossible. How does it do this? It does this by decreasing the body's sensitivity to thyroid hormone so that the body looks hypothyroid.Thyroid hormone levels are normal or low normal, but the sensitivity to thyroid hormone is decreased. Thus, even if the thyroid hormone levels are normal, the body's reaction to the thyroid hormone is muted. So women with Estrogen Dominance appear to look hypothyroid or low thyroid.

Thyroid hormone controls the metabolism of the person. More thyroid and the metabolism goes up (hyperthyroid). Less thyroid and the metabolism goes down (hypothyroid).

What does a woman with hypothyroid look like? Hair begins to thin. The body temperature is low. Fat builds up on the belly and hips despite exercise and diet.Even with exercise and diet it very difficult to get rid of the fat on the belly and hips. The women feel cold. There may be sugar cravings. The eyebrows may look thin and begin to thin. She begins to feel a lack of energy and sluggish.

Typically, she goes to see the doctor, and a thyroid blood test is done. The thyroid hormone test is normal or low normal. The doctor usually shrugs and says she is normal, and waves goodbye to the patient. But I don't know what woman is happy with thinning hair and fat on the belly and hips with weight gain. The smarter doctor will give her a little thyroid. She looses the fat on the belly and hips and weight gain and the hair grows back. Weight loss is easy. And the patient comes back to see the doctor every so often to get a refill on the thyroid hormone. Everyone is happy.

I talked to a "smart" specialist that noted that every time he gave synthetic estrogen replacement to a woman, he noted that they began to look hypothyroid despite having normal blood tests. Naturally, the women were unhappy with thinning hair and increased fat on the belly and hips. So he began to give them a little thyroid hormone. Hair stopped thinning and the fat on the belly and hips stopped. The women were happy. So after several years he began to give synthetic estrogen replacement and thyroid hormone together. This would prevent a repeat trip from his patients complaining about thinning hair and fat on the belly.

In contrast, natural estrogen (as opposed to synthetic estrogen) that your body makes could actually increase your hair, IF you do not have too much estrogen (Estrogen Dominance) to begin with.

Here is a rabbit trail. If you do need to take thyroid hormone, I would suggest that you take Armour Thyroid or Biothyroid. There are two thyroid hormones, T3 and T4. T3 is the more active of the thyroid hormones. T3 has 3 Iodine molecules on it. T4 is the less active of the thyroid hormones. T4 is converted to T3 by a converting enzyme in the human body. For those that are very allergic, diabetic type II, and other chronic conditions, there is frequently a lack of the converting enzyme that converts T4 to T3. For these people, simply giving T4 like Synthyroid does not cut it. The better choice is to give BOTH T3 and T4, so a converting enzyme is NOT needed. Armour thyroid and Biothyroid contain BOTH T3 and T4.

Hopefully, you can be even smarter in treating your hypothyroid condition. Get rid of the cause of the thyroid receptor desensitivity. Estrogen Dominance from xenoestrogens and phytoestrogens is causing the hypothyroid condition by decreasing the thyroid receptor sensitivity. So just get rid of the xenoestrogens and phytoestrogens, and the thyroid receptor will wake up! Progesterone Cream will also oppose the effect of estrogen and Estrogen Dominance. Wake up the thyroid receptor with progesterone cream and avoiding xenoestrogens and phytoestrogens.

Typically, avoiding xenoestrogens and phytoestrogens, and using progesterone corrects the hypothyroid problem in 2-6 months, but not always. Fat on the belly and hips goes away without dieting or exercise. The need for thyroid supplements also goes away. Hair loss stops and the hair becomes thicker. When the thyroid receptor sensitivity comes back to normal, you must be careful NOT to have too much thyroid hormone. Work with your doctor, to make sure that that you do not have too much thyroid hormone, if you are taking a thyroid supplement. Too much thyroid hormone caused by too much thyroid supplement may result in a dangerous "thyroid storm".

If the hypothyoid symptoms do NOT go away, usually the patient has some kind of xenoestrogen or phytoestrogen in her environment. This is the most common reason for failure for progesterone therapy.

Another less common reason for failure, is that the patient has fear/stress/anxiety that prevents the xenoestrogens and phytoestrogens from being excreted.

Another reason for failure is that the patient may be poisoned with a chemical that blocks thyroid hormone. One type of fire retardant PBDE commonly used in plastics is the classic example of a thyroid blocker. Since PBDE fire retardants are structurally similar to thyroid hormone they can block thyroid hormone. People in the United States have the highest PBDE levels in humans worldwide. Women in North America have 10 to 40 times the levels of the PBDEs in their breast milk, as do women in Europe or in Asia.

Another common cause for hair loss is toxic chemical exposure (unrelated to Estrogen Dominance). It is sort of like chemotherapy. The chemotherapy is toxic to the rapidly growing hair follicles and the hair falls out. The most common cause of toxicity with hair thinning is exposure to chemicals in a new building or living in a newly built house. The solution is to open the window and get fresh air.

Progesterone can help with ovarian cysts, fibroid, endometriosis, pms, fibrocystic breast disease, and menstrual cramping. Most of the time, the women with these diseases also suffer from hypothyroid from Estrogen Dominance causing thyroid receptor to become less sensitive.

Hear what it's saying and on the face of it , it's sounds logical- ish. BUT I have in the past had breast cancer and it was caused by estrogen 100 percent score and also progesterone 100 percent score Not just estrogen dominance, so one does have to be so careful with messing with these hormones,sometimes we make one problem whilst helping another!
