The more you worry, the more you throw off the delicate balance of hormones required for health - Andrew Bernstein

"Bisphenol A (BPA) is a known endocrine disruptor that hijacks the normal responses of hormones. Yet, traditional toxicology studies indicate that only very high doses of this chemical affect exposed animals - doses as high as 50 mg/kg/day. For the past decade, scientists have used modern scientific techniques to probe the effects of BPA on numerous endpoints that are not examined in those traditional toxicology studies. Examining these non-traditional endpoints reveal a very different story. Because of increased understanding of the mechanisms by which hormones and chemicals that mimic hormones work, it has recently become clear that endocrine disruptors need to be studied at much lower doses.
As a consequence of this new understanding, a group of scientists that study endocrine disruption worked together to update and refine a 2007 review of the low dose effects of BPA. The group not only added hundreds of more recent studies, but they also used an integrative biological approach to scrutinize low dose effects of BPA at multiple levels of biological organization: on cells, animals and human populations.
The findings are striking. When looking at the "low dose" literature as a whole, reproducible effects were seen in animals after exposure to incredibly low doses of BPA. In fact, effective doses were ten to forty times lower than the doses identified in traditional toxicology studies. Several dozen "low dose" studies show effects of BPA at doses that humans are thought to encounter in their everyday lives.
These scientists detail in their article the effects of BPA exposure both in vitro and in vivo, and how it contributes to a large range of health problems in humans, such as polycystic ovarian syndrome, immune response to allergens, behavioral problems and decreased fertility. The effects on wildlife are also widespread.
With the knowledge that such tiny amounts of BPA can have such far-reaching implications for humans and wildlife, stricter regulations of this chemical and other endocrine disruptors should be fast on its heels."

The Toxic Brew in Our Yards
In 2009 the Endocrine Society, a group of doctors, researchers and educators who specialize in diseases related to the hormonal system, published a scientific statement based on 485 citations from research papers showing growing evidence that there are significant health threats caused by endocrine-disrupting substances in our environment.
A site primarily aimed at health professionals but is also widely used by patients who want to understand more about the management of their conditions.
Since its launch in the late 1990s by James Norman, MD, EndocrineWeb has emerged as the premier site addressing endocrine disorders. Today, the site receives more visits than any other general endocrine site.
From the beginning, EndocrineWeb's goal has been to provide patients with accurate and current information about endocrine disorders. In clear, straightforward language, we explain the causes and symptoms of these disorders and how they can be treated. We are committed to presenting trustworthy, high-quality information.
One of the main reasons I've published this site is because I get the impression most pituitary patients have to deal with major problems on a day to to day basis. Yet, as a person who has had to go through puberty and adulthood without a pituitary gland, I lead a very good quality of life and I just wanted to offer some hope to those with pituitary problems.
Hormone Health Network
The Hormone Health Network helps you and your health care provider have more informed discussions about hormones and health. Our free, online resources come from the most advanced clinical and scientific expertise in endocrinology.
WELCOME! This site is dedicated to providing reliable information for those who want to be informed about their bodies and the hormonal system that affects us all.
Men and women, children and teens are affected by hormones. Hormones are amazing components of our bodies and when in the right balance help our physical and mental health function properly. Hormones are important and necessary for growth and health.
In 2011 Stacey did just that when she publicly shared her health journey from diagnosis, to treatment, to acceptance of the thyroid autoimmune condition she has. Since then she has become a mom and continues to raise awareness for thyroid and autoimmune conditions.
The Endocrine Post
Welcome to the official blog of the Society for Endocrinology. We are a membership organisation which supports researchers and clinicians working within the field of endocrinology.
While our members aren't out making a difference to the world of hormone science, you might find them here, sharing their news, ideas and advice.
The NET Community
Information, support, and insights for people affected by neuroendocrine tumors.
The Testosterone Deficiency Centre
Replacing Testosterone is now known to be beneficial in the treatment of a large number of diseases and conditions. The AACE now suggest General Practitioners need to be more aware of the need to detect and treat Testosterone deficiency, as its importance to the health and well being of men and women is now becoming too clear to ignore any longer.
You & Your Hormones
Welcome to You & Your Hormones, a new web-based project by the Society for Endocrinology that aims to give patients and the general public access to reliable online information on endocrine science.
AutoimmuneMom.com was born out of a frustration with a lack of online information about autoimmune conditions beyond the surface-level articles and blog posts, even on the top health websites. Believing there must be a way to develop content that dug into current research and examined deeper questions, the planning for the site began. And because moms are amazing resources for all things related to their kids, why not also create a way for them to help each other find new ideas for managing their autoimmune issues? After all, women are the majority of people affected by autoimmune, and many of us are moms.
You might say endocrine (say: en-doh-krin) glands are a little bossy – they tell your cells what to do! But that's actually a good thing. Without your endocrine glands – and the hormones they release – your cells wouldn't know when to do important things.
For instance, your bones wouldn't get the message that it's time for you to grow and get bigger. And your body wouldn't know that it's time to begin puberty, the body changes that turn kids into grownups.
You have a variety of endocrine glands in different sizes and shapes located in different parts of the body.
The endocrine system sends signals throughout the body, much like the nervous system, but unlike the immediate responses triggered by the nervous system, the effects can take a few hours or weeks.
Medical News Today
The latest Endocrinology News articles published daily. Includes news on internal or hormonal secretions and their physiologic and pathologic relations - including thyroid diseases, menopause, cancers of the endocrine glands, hormone replacement and much more.
The endocrine system is made of eight major glands, which are groups of cells that produce and secrete chemicals. A gland selects and removes materials from the blood, processes them, and secretes the finished chemical product for use somewhere in the body. Almost every organ and cell in the body is affected by the endocrine system.
