Complex Relationship Between Body Fat and Your Brain Hormones

Body composition has a very complex relationship between fat, hydration, muscle, and bone mass. The regulatory hormones that control each are integrally linked and seem to control how we gain or lose weight, how the weight is distributed, how fit we are, how much muscle we can build as we get older and many other aspects of our health.

To help understand this complex relationships how fit you are is more accurately measured by body composition readings than BMI. Specifically knowing your relative skeletal muscle mass can determine if you have an appropriate amount of strength for your gender and age. Knowing your body fat, and the differential between your visceral fat and your overall fat percentage can help determine your overall leanness. It is important to be lean for thermoregulation. Once it was thought that heavier women would have fewer hot flashes because of overall higher estrogen levels. Then the prevalent theories were that body fat functions as a natural 'sweater layer, and it was postulated that women with increased Body Fat Percentages had more hot flashes.

In a new study published in Nature in May of 2017 Mone Zaidi and colleagues tested the theory of FSH, a brain hormone that is involved in the regulation of ovulation in younger females, can be involved in how the body begins to accumulate more deep fat deposits as a person ages. The researcher gave an antibody to bind and thus lower the the pituitary hormone FSH (follicle-stimulating hormone) and showed that with this treatment increases bone mass and reduces adiposity in mice that have had their ovaries removed and much lower estrogen levels. The antibody treatment also reduced adiposity in premenopausal mice fed a high-fat diet, in part due to increased metabolism and oxygen consumption. It is thought this can both help explain some of the complex relationships between fat and the cascade of brain hormones that are responsible for our body composition.

The thought is that in our fat, our largest endocrine organ, some hormones are converted to estrogens. The theories have always had a few problems. The amount of hormone produced by the fat is small, and the hormones produced are weak as well. Some studies indicate that a woman's weight and BMI may not be as directly related but it is the amount of fat. We notice that the relationship between hot flashes and weight and BMI seems to change as women get older, and with careful body composition we now see that the amount of fat in a woman's body also changes as women age, and this body fat percentage is probably the key factor, not the absolute weight.Now we can explain this more accurately by understanding the relationship between the elevation in FSH in menopause and the weight issues, as well as bone loss, that occurs at this time.

Passing Your Uterine Lining, Menstrual Period Norms

Decidual Cast Periods can be fairly easy, passing some tissue at a time, or off can come the whole lining in one piece called a decidual cast. Generally the lining of the uterus is only 6-8 mm thick at the time of the menstrual period, and it is shed gradually, a few cells at a time. The decidual cast is when the entire lining passes spontaneously. It's not uncommon, but it usually both uncomfortable, and alarming to some. But us women are designed to have some sort of periods Or Not? We have to pass tissue each month. Or Not? Are they good for us? Or Not? Do we want them? Or Not? Is this something that is individual? Or Not? It's a complex topic that I will be discussing a lot over my time in this blog. So lets start with basics: How much do we bleed and what are we loosing, and just what was this that the patient passed? And another basic: track your periods, and the Women's Health Practice site http://www.womenshealthpractice.com/media/pdf/menstrual_chart.pdf you...

Post-Endometrial Ablation Syndrome

If you have had an endometrial ablation and have developed symptoms of pelvic pain you might have post endometrial ablation syndrome. What is post-endometrial ablation syndrome? It is a constellation of symptoms due to entrapped blood or tissue within a uterus that has previously undergone an endometrial ablation. We are able to diagnose this at Women's Health Practic e but occasionally other conditions are causing similar symptoms. Other complications of endometrial ablation include pregnancy, risks from pre-existing conditions such as a polyp or fibroid, an infection of the uterus, or a pregnancy. If you have had a tubal ligation then it is possible that the condition could be post-ablation tubal sterilization syndrome. The ablation procedure is designed to destroy all lining tissue, but in fact there is no way to confirm the completeness of the ablation. It is thought that either residual or regrowth of the tissue is producing the symptoms of post-endometrial ablation syndrom...

You Have an IUD: But a Positive Pregnancy Test

Fortunately IUD pregnancy failures are rare. But if you have an IUD for contraception, and you get a positive pregnancy test, you probably ask yourself, what next? Well, make your gyno appointment promptly, this is a condition that is not typically an emergency, but it can be and it’s not handled over the phone or on a blog, or through self diagnosis! That being said, some researchers from University of Texas Southwestern Medical Center in Dallas decided to look back at over 4100 women who had IUDs and of those 42 cases who became pregnant in their institution, over about a year period of time, to help understand what these women could expect when they got to their gyno and what actually happened to their pregnancies. Accurate pregnancy diagnosis, pelvic examination, and pelvic ultrasound were the cornerstones of the evaluations. They had very specific ways they looked at their ultrasound to prove there was no pregnancy in the fallopian tube, or partially in the fallopian tube...
