  • Do Genetic Tests Really Work?

    MEDICAL NEWS

    You may have seen ads for genetic tests. These tests claim to tell you about your health. They might tell you if you’re at risk for a certain disease or if you should eat a certain diet.

    Big promises from companies

    At-home genetic tests may sound exciting, and companies advertise them as “the answer” to many health issues. But the Food and Drug Administration (FDA) and the Centers for Disease Control and Prevention (CDC) say you should be careful about using these tests.

    Before you spend a lot of money on one, keep in mind that the test may not have any science to back up its claims. Others may give you some good information, but the information is only useful if you also have a complete medical exam.

    The FDA and CDC say that genetic tests are complex. They say that the results can be hard to understand without having appropriate medical knowledge.

    Just a snapshot

    Many genetic tests look at a few of your body’s genes. But you have more than 20,000 genes in your body. If you get a “positive result” for certain genes, it could mean:

    *  You have a certain disease.

    *  You have a higher risk of getting certain diseases.

    *  You are a carrier for a certain disease.

    But even a positive result doesn’t tell the whole story. You may never get the disease that comes back “positive.” Or if you do, it may not be severe enough to cause any serious health problems.

    A negative result means the lab didn’t find any unusual changes in your genes. While this can be good news for certain diseases, it’s not foolproof. It doesn’t mean you’ll never get a disease or have health problems. It’s also possible that the test didn’t look at other genes that could be important.

    Many factors at play

    Genes are only one piece of each person’s health story. Your environment and your lifestyle also play huge parts in your physical and mental health. Don’t rely on genetic tests to make any health promises. Instead, see your doctor regularly and follow a healthy lifestyle. That can mean more than a few genes.

    When genetic tests are part of a medical exam, they can be helpful. Your doctor can help you decide if you need genetic tests. If you do need them, make sure a medical professional reads your results.

  • Getting Fit In Less Time

    BE FIT

    Have you heard of interval training for exercise? You may have assumed this type of exercise is only for athletes. However, people of almost all fitness levels can use it.

    Interval training means you add short bursts of more intense activities into your regular exercise routine. How fast and how long you do your intervals is completely up to you. This can be as simple as 10 seconds of running and then 4 minutes of walking. If that’s not possible, alternate brisk walking with slower walking.

    Intervals don’t have to be more than a few seconds. One of the biggest advantages is that you don’t need any special equipment to get started!

    Why should I do it?

    The American College of Sports Medicine (ACSM) says interval training has several benefits, including:

    *  Burn more calories: Even if you can only do short intervals, you’re still burning more calories than if you hadn’t done the intervals at all.

    *  Most of your time: Many people can’t find time for longer workouts. Instead, use the time you have to work harder with intervals.

    *  Boost mood: Exercise releases endorphins. These are feel-good chemicals in the brain. More vigorous exercise may release more endorphins than only doing light exercise.

    *  Fight boredom: Doing the same exercises all the time can lead to boredom. But, mixing it up with intervals can help keep you interested.

    *  More aerobic fitness: Higher intensity will improve your cardio fitness. With time and practice, you’ll be able to exercise harder and longer.

    For beginners

    *  Choose a distance if you don’t want to count or use a stopwatch. For instance, jog or walk briskly to the next tree or driveway.

    *  If using equipment like an elliptical machine or bike, alternate faster bouts of that exercise with your usual pace.

    Interval training can be done at your fitness level. But, don’t be too aggressive at first because you could get an injury. While you want to get your heart pumping, you don’t want to make it so hard that you can’t stick with it.

    Studies suggest that interval training can be safe and helpful to most people. Ask your doctor before starting a new exercise plan to be sure it’s right for you.

  • Pregnancy Tests

    Pregnancy & Prenatal Care

    How can you find out for sure if you are pregnant? Do a home pregnancy urine test. You can do one yourself. Facts about these tests:

    *  They test for a hormone called HCG. HCG is present in the urine only during pregnancy.

    *  You can buy them over-the-counter. Look for them at the drug store or supermarket.

    *  They are 95 to 100% error-free. But you have to do what the label says.

    *  They come in many brands. Some brands include a second test in the package.

    *  They are not all used the same way. Read the label to find out what to do. Some can be used the day after you miss a period. That’s about 14 days after conception. Some have you wait 3 to 5 days after you miss a period. Some have you use your first morning urine sample.

    {Note: If your test is positive, call your health care provider. Make a date to be seen. Ask what prenatal vitamins (vitamin pills) you should take. Do this if you are not already taking them. It is a good idea to start taking prenatal vitamins before you get pregnant and right at the start of pregnancy. Doing this, especially getting enough folic acid, may prevent some birth defects. Prenatal vitamins will supply the minerals you need, too.}

    *  Get a lab or in-office urine test. Ask your health care provider to order one. Facts about these tests:

    – They test for HCG in the urine.

    – They are nearly 100% error-free.

    – They can confirm pregnancy 7 to 10 days after conception.

    *  Get a blood test. Ask your health care provider to order it. Facts about these tests:

    – They test for HCG in the blood.

    – They are 100% error-free.

    – They can confirm pregnancy 7 days after conception. That’s even before you miss a period.

    Always follow up your pregnancy test with a medical exam. Your health care provider can see signs of pregnancy by or even before the 6th week!

  • Exercise Benefits Outweigh The Struggle At Any Age

    BE FIT

    The more you age, the more you need exercise to stay independent and healthy, said Dr. Keith Veselik, director of primary care at Loyola University Health System. “Around age 35 is when our muscle mass and resting metabolism starts to decrease. When this happens our bodies require more, not less exercise to manage our caloric intake. When this starts to happen, we can eat the same things, do the same things and may gain 3 pounds a year. That’s 30 pounds in a decade,” he said.

    Dr. Veselik said the best workout program balances heart healthy exercise, strength training, and flexibility. He recommends an hour of cardiovascular exercise 4 days a week, 2 days of strength training for 30 minutes, and balance and flexibility exercises such as stretching, yoga or pilates, 1 to 2 times a week.

    In your 50s:

    *  Muscle and joint aches and pains start becoming more apparent, so get creative about how to keep up cardiovascular exercise that is easy on the joints but gets the heart rate up (hint: swimming, biking, or running on softer surfaces).

    *  Cardiovascular exercise also helps to fight many of the most common and deadly medical concerns, including heart disease, asthma, and COPD.

    *  Don’t go from doing nothing to running a marathon. Talk to your doctor, ask about risk factors, and together create a plan that’s right  for you.

    *  If back pain occurs, protect your back by building strong core muscles and make sure you are lifting heavy objects correctly.

    In your 60s:

    *  Balance and strength should be a major focus. Many people are scared of breaking a hip, which can limit independence.

    *  Bones aren’t as strong and both men and women become more prone to osteoporosis.

    *  Add balance and leg strengthening exercises to increase flexibility, as well as balance to help prevent accidental falls. Weight-bearing exercise is crucial to bone health and keeping bone density strong.

    *  If arthritis develops at this age, exercise can help you cope. Swimming or aquatic classes are especially good.

    *  Walking is a great form of exercise. Just make sure you get your heart rate up.

    In your 70s and beyond:

    To combat seniors’ biggest worry, dementia, know that exercise is the only thing that is proven to prevent Alzheimer’s disease. And many of the major risk factors for dementia – high blood pressure, high cholesterol and diabetes can be countered with exercise.
