Facing 50 and Menopause: The Tests You Need to Take After the Transition – May 2, 2012

The last third of a woman's life can be a very rewarding and dynamic time. Menopause, the end of one's menstrual cycles, is an entry point into this time, and a great time to "pause" at the threshold to ensure you're taking steps to stay as healthy as you can for the duration.

The average woman reaches menopause at the age of 51; you'll know you are there if you have missed a full year's worth of periods. If you suspect you're entering menopause, it's a good time to see your doctor. He or she can work with you to make sure you receive some important and potentially life-altering screening tests. Life altering, because the post-menopause years can be associated with chronic diseases such as osteoporosis, heart disease, and diabetes. The good news is that these diseases may be easy to detect early and can be treated or even beaten with decisions you can make with your doctor and actions you can take. [+more]


Urinary Incontinence: Steps You Can Take – April 30, 2012

Imagine not being able to sit through a movie or a meeting without having to take a bathroom break. Or not being able to pick up your grandchildren, sit through a movie or exercise without risk of urinary leakage. Nearly 13 million people in the U.S. suffer from urinary incontinence (UI), a disorder that is often so distressing that they choose to stop some of life's most pleasurable activities rather than seek help. UI is surprisingly widespread, and while the chances of it increase with aging, it is not inevitable. That's why I chose to discuss UI on The Doctors, to help people shed their shyness and take on a problem that can be addressed.

There are many conditions that can cause incontinence, including stroke, diabetes, and changes associated with growing older - though UI can happen at any age. And there are different types of incontinence. If activities like sneezing, laughing, coughing or carrying heavy objects result in leakage, it may be stress incontinence. People who have a strong need to urinate and don't reach the bathroom in time are experiencing urge incontinence. It is not uncommon for some people to experience both types of UI. [+more]


Alzheimer's Disease — The Prospects for Progress – February 29, 2012

I'm often asked why it's taking so long for new treatments to emerge for Alzheimer's disease. That's a critical question, not only for people challenged by Alzheimer's and caregiving for it, but also for our national health outlook. Like many of you, I know at first hand the heartbreak of Alzheimer's and the stress of dementia care. I also see the alarming statistics about the rise of Alzheimer's as members of my generation-the Baby Boomers-move into their seventh and eighth decades. Right now, our society will be hard pressed to afford the kind of care that the projected epidemic of Alzheimer's will bring.

So why are new treatments taking so long? A host of factors. The human brain is a complex organ, one that we are only beginning to understand. Alzheimer's symptoms can mimic those of other diseases. Alzheimer's diagnosis is still an imperfect science-while experts can usually diagnose it correctly, the only way to confirm the existence of plaques in the brain outside of the research setting is through autopsy. There are still competing theories as to what causes Alzheimer's. Tracking the progress of the disease is difficult-we don't have the equivalent of the blood pressure cuff for Alzheimer's. Perhaps most striking, only recently have advances in public health and medical science allowed enough people to live long enough to expose Alzheimer's as a serious health issue. Today, the "super-elderly"-people over 85-are among the fastest growing cohorts of Americans, and they are at highest risk of age-related dementia.[+more]


If It's Cancer, Ask Your Doctor About Testing – January 18, 2012

Just about everyone has some personal experience with cancer — whether through a friend or family member, or through their own battle with the disease. The good news is that in recent years, medical science has brought many new advances in cancer diagnosis and treatment, and new options for patients.

It is important to know how to recognize cancer's symptoms, because earlier detection means better outcomes. Symptoms of cancer can mimic those of other diseases. Listen to your body and talk to your doctor if you notice anything out of the ordinary. The American Cancer Society recommends that everyone over age 20 add cancer screening to their regular examinations (tips for early diagnosis can be found on the ACS website — link at right).

It is also important to know that all cancers are not alike. For example, we now know that "breast cancer" is not one disease but several different ones; in all, the cancer cells begin growing in the breast, but the cancer cells themselves are different types or may grow in different ways. The same is true for cancers of the colon, lung, blood, etc.[+more]


Quitting Smoking – December 13, 2011

Smoking is not just a bad habit; it's an addiction. This was one of the most important things I wanted to get across when talking with Drs. Travis and Ordon on The Doctors. My mother was one of the strongest women I have ever known. I believed she could do almost anything. But the one thing she could not do was quit smoking. Unfortunately, smoking, as a risk factor for stroke, helped lead to her death.

Today, over 46 million people in the United States smoke. The effect of this smoking goes beyond the 46 million. Millions of people are affected through exposure to secondhand smoke.

Smoking is responsible for an estimated $96 billion in public and private health care costs. More importantly, smoking and exposure to smoke kills over 400,000 people in the United States annually, according to a November 2011 report released by the Centers for Disease Control and Prevention. Making the decision to quit is one of the most important decisions you can make to improve your health.[+more]


Differences Can Make a Big Difference – November 23, 2011

People from different racial and ethnic groups have different biological responses to both diseases and their treatment. Whether we are talking about liver cancer in Asians, asthma and stroke in African-Americans, or diabetes in Hispanics, these are just a few of the devastating chronic diseases that affect different groups at different rates. Scientists and doctors argue about "cause and effect" here — how much is genetic and how much is a result of diet and other factors. One thing is for sure. Diversity in clinical trials is necessary to test for differences in outcomes and to improve the safety and efficacy of therapies for all people.

There are about 35,000 clinical studies underway today, and patient-volunteers, lots of them, are needed. In fact, without trial participants, groundbreaking medical research would come to a grinding halt. Moreover, the investigators who manage clinical trials need participants of different ages, gender and ethnicities, because the real world is made up of all kinds of people. Diversity in clinical trials helps illuminate the factors that cause differences in disease rates and pave the way for more effective medicines and medical procedures.

Talk to your doctor if you want to learn more about participating in a clinical trial. They aren't without risks, and you will have to judge whether the risks are worth the benefits that may be available to you. But for those of us who work in biomedical research, clinical trial participants are the unsung heroes who enable the advance of medicine. Check out the links in the resource section to find out more about clinical trials. Also, in the video box on the right, you can watch my segment on The Doctors where I talk about how clinical trials work. In the video, you'll hear first hand from a clinical trial participant who made a difference in medical progress.


The Power to End Stroke – November 15, 2011

My last post focused on the need to respond quickly if you suspect someone is having a stroke. There, every minute counts, and counts for a lot. Today, though, I want to talk about the steps each of us can take, over time, even over years, to help reduce the odds of a devastating stroke. Even small changes in lifestyle can add up to reduced risk. [+more]


Stroke Signs – November 1, 2011

Stroke is the third leading cause of death in the United States. On The Doctors, I shared my thoughts on this important health issue and what we can do to prevent stroke. As I put in my previous post, it's crucial to call 9-1-1 when you think someone's having a stroke. Remember, Act F-A-S-T. Check your local CBS listings to see the whole show or watch the segment to the right.


A Stroke Is an Emergency! – October 27, 2011

I am writing this a few days before Halloween, which seems fitting — because there are not many things scarier than a stroke. Like a heart attack, a stroke can come on suddenly, with little or no advance warning. And like a heart attack, a stroke can cause serious and lasting damage, or it may be fatal, especially if you don't respond quickly.

That's why it's very important to know stroke's warning signs and if you see them, call 911 immediately. A quick response can literally mean the difference between life and death. Warning signs of stroke include sudden: [+more]
