Unopposed estrogen dominance can interfere with thyroid dysfunction. Commonly obsereved symptoms of hypothyroidism(underactive thyroid)
include fatigue, constipation, muscle weakness, memory loss, infertility, swelling of hands, feet eyelids, dry skin, intolerance to cold and heat, indigestion, menstrual disorders,sleep disorders, loss of hair, emotional instability, premenstrual syndrome,and weight gain.
Estrogen and thyroid are two hormones that have many opposing actions, probably at the thyroid hormone-receptor level. Unopposed estrgen will prevent the thyroid from performing its normal activities and can lead to relative hypothyroidism DESPITE NORMAL BLOOD LEVELS of thyroid hormone. Progesterone, (the natural kind only)being a normal counterbalance to estogen, inhibits many of estrgen's undesirable effects, including its interference with thyroid hormone activity. It is strongly suspected that a majority f women with mild hypothyroidism would be better treated with progesterone cream than with thyriod meds. When there is estrogen dominancek, there is also a decrease of libido with mood swings and irritability, depression, and headaches, all symtoms of hypothyroidism. Natural progesterone is the source of libido or sex drive in women and markedly increases libido in men.
Another contributor to hypothyroidism is iodin deficiency. Over 85 years ago, we thought we had solved the problem of widespread iodine deficiency by adding iodine to salt. Unfortunately, for the pasy 50 years physicians have recommened minimized salt intake. During this same time the entire world has suffered a marked increase in nuclear radiation: ironically, it is the thyroid gland that is the most sensitive organ to radiation damage. Finally, we have been advised to increase our intake of cabbage, broccoli, and cauliflower (the brassica family) for their protective effects on the colon. But all these foods block thyroid use of iodine to make thyroid hormone. 90% of individuals have periods of low body temp., a prime feature of hypothyroidism going on. Iodine replacement restores normal body temp.s (get a good natural on with no fillers. usually found in kelp) Individuals with low body temps. may suffer even more because of either estrogen dominance or progesterone deficiency or both.
For those with low body temps., it is recommended iodine supplementation of 1.0 mg per day for six weeks. If the body temp. comes up to normal (97.6 in the A.M. and 98.6 in the P.M., temp. taken by mouth), then continue with just 300to400 micrograms per day.
Hi Diana. Thank you for the insightful post, but I have to say it may be somewhat misleading out of context from the rest of the article.
I'm a great proponent of Dr. Lee's progesterone article and I used Natural Progesterone for a number of years. However, I do not find it to be a replacement for thyroid hormone as he suggests in the passage you quoted. In fact, my hypothyroid symptoms continued while using progesterone cream, and my thyroid cancer was diagnosed two years after I started the progesterone cream.
Progesterone definitely supported me until my thyroid levels were balanced (even helping with my endometriosis), but I found that my menstruation became abnormal when I continued the Progesterone after my thyroid medication was helping. I had also started taking Maca by then (which also supports the hormones), so the progesterone may have become redundant. I have since stopped using the progesterone cream and feel much better. Perhaps my estrogen dominance was corrected after my surgery (helped by my Synthroid, the Maca, or both).
But, while it may support, I feel that it is dangerous to suggest that progesterone is a replacement for thyroid hormone.
The same can be said for the use of kelp and other iodine supplements. I haven't studied much about them, but I understand that it may be potentially harmful to ingest large quantities of iodine if we have not been found to have an iodine deficiency.
I hope this post doesn't sound too negative. Dr. Lee's work is quite useful and I still think it can help many people (including thyroid patients). But we have to be careful when self-treating, particularly when it comes to hormones.
Good health to you. <IMG SRC="http://www.healthboards.com/ubb/wave.gif">
I am going to echo Artful's sentiments, especially regarding Iodine. When I realized that I had a thyroid problem, i started taking Kel to see if that would help. It made my symptoms WORSE rather than better, and my basal temps stayed low.
On the progesterone, I would say the same thing. Too much can be detrimental and it is possible to have enough and still be hypo.
Niecey wanted more info, I was just typing the info that was in the book. I think maybe you are correct. I personally and on synthroid. I had cancer of the thyroid in 1989, and Iam also on Tri-est which is spendy, but the closest natural estrogen replacement you can get, I got the recipe from the same book. So you see the thyroid part doesn't apply to me. I'am also on the watercure diet. But again mineral based sea/salt doesn't have a significant amount of iodine.
Which I don't need with the med. Im on.
I am on the prog. cream too. Iam just over on the synthroid so my thyroid shuts off completely. My skin was so dry before I started this cream. I know I feel better.
I should of listed the symtoms and directed others to get tested for their levels first, next time I will use better judgement. Thanks for the pointers. I know not everyone is the same. Diana
