Getting it Right: Estrogen Replacement in Women

By Dr. Jerry Mixon June 21, 2012

I’ve written about this before, but it bears repeating. In spite of what people often say, estrogen is not a hormone – estrogen is a class of hormones. When a female patient comes to Longevity Medical Clinic and we start discussing Hormone Replacement Therapy, it’s critically important that we use the right type of hormones to accomplish our goal. Women can benefit dramatically from Hormone Replacement Therapy. But they need to receive human type hormone, in doses that maximize benefits while minimizing risks, and the hormones should never be given by mouth.

Do Our Labels Tell the Whole Story?

By Dr. Jerry Mixon April 29, 2011

We human beings seem to like to label things – the simpler, the better! This urge to put everything into simple categories definitely applies to drugs and supplements – we like to think that Drug A always has one particular effect, and Supplement B has a different one. Just take this pill or use this crème and, voila, you always get one simple outcome.

That may be tidy, but it’s seldom accurate. In the real world, the drugs and supplements we take usually refuse to cooperate with this fantasy. Instead, one compound can have many effects – and many compounds can have similar effects. Often none of these interactions seem to correlate very well to the labels we put on them.

Take Mice Studies with a Grain of Salt

By Dr. Jerry Mixon March 18, 2011

Are clinical trials using animal studies always valid for humans? Consider me a skeptic.

I frequently see advertisements and newsletters (even some written by physicians) that promote lab tests and treatments based entirely on studies done using rodents. These “experts” frequently draw conclusions from these studies that their lab test or product is a breakthrough of vital importance to humanity. While it may be true, all too often it’s not.

Let me give you a recent example of a study done in mice that could lead to the conclusion that every woman with breast cancer should be taking very robust doses of the adrenal hormone DHEA. This study should serve both as an encouragement and as a caution, an example of the care we must exercise when we use animal studies to draw conclusions about humans.

Do Doctors Know Everything?

By Dr. Jerry Mixon September 14, 2009

Some patients get upset if I will not accept, on faith, that their latest homeopathic, holistic, ionized, wheat grass remedy (you get the idea) was unlikely to cure their arthritis. Many years ago I accepted the fact that there are many things I do not, and probably never will, know.  But I like to think I know SOMETHING.

I think the perception that we doctors don’t know anything derives from how often patients get told crazy, conflicting health advice. Consider a man who was born in 1949 who would be about 60 now. In his lifetime, he would have seen doctors talk about which brand of cigarettes had the greatest health benefits and that a hearty breakfast of bacon and eggs was healthy. However, he would also remember being told that the cholesterol in eggs and bacon would kill him but then he’d recall being told that maybe it wasn’t as bad as we originally thought. More recently, he has probably heard that there is good and bad cholesterol and he needs to get
