Ride a Bike

Biking -- in a group or alone, outside or on a stationary bike -- builds stamina and balance with less impact on knees, hips, and other joints than walking or jogging. Recumbent and comfort bikes can provide relief for people who are uncomfortable on upright bikes. If you have a medical condition, check with your doctor before starting any new fitness program. Depending on your condition and health, some exercises may not be recommended.

Practice Yoga

Yoga is a gentle way to improve posture, balance, and coordination. Several early studies suggest yoga helps the physical functioning of people with arthritis and promotes relaxation. Look for a beginners' class and explain any physical limitations you have to the teacher. Once you're comfortable with the poses and breathing, you can also practice yoga at home.

Exercise in Water

Swimming, water walking, and other water-based exercises are ideal for relieving the pain and stiffness of arthritis. The resistance provided by water increases strength and range of motion, while its buoyancy supports the body's weight, reducing stress on joints. Water workouts can be as strenuous as swimming laps or as gentle as a game of tag in the shallow end.

Add Short Bursts of Activity

Physical activity in small amounts really adds up. Vacuuming or 10 minutes of pruning may be easier to incorporate into a busy day than an hour of exercise. Always try to use correct posture -- such as standing rather than stooping -- and let your larger joints handle as much of the work as possible. To track your activity, wear a pedometer and record how many steps you take each day.

Set a Goal

Commit to a greater level of training by signing up for a 5K walk, bike ride, or other organized event. Registering for an event increases your commitment and motivation to train. It may give you extra motivation to join events that support causes you may believe in, such as arthritis research. Be sure to give yourself enough time to train. Work backward from the event to set specific, realistic training goals.

Try Tai Chi

Studies suggest that tai chi, a traditional Chinese martial art, reduces pain and stiffness in many arthritis patients. Tai chi combines slow, gentle movements with a mental focus. It can be practiced in groups or alone. Participants in these studies also reported improved balance and lower levels of depression.

Maintain Sexual Intimacy

Pain from arthritis can affect every part of life, including sexuality. But a fulfilling sex life is possible. Plan for sexual activity during times when you feel rested, avoid cold temperatures, use pillows to support painful joints, and relax muscles and joints with massage. Communicate openly with your partner and strive for emotional and physical closeness.

Walk the Dog

Take your four-legged friend when you run errands on foot or head out for a lunchtime stroll. Walking the family pet around the block can deliver a low-impact, inexpensive workout. Walking can reduce stiffness, increase bone mass, increase energy, improve mood, and reduce anxiety.  Try to accumulate at least 150 minutes a week. This could include 30 minutes of walking or any other moderate-intensity "lifestyle" activity, three to five days a week.

Take a Hike

At home or on vacation, hiking is an active way to explore the outdoors. Vary the trails you use, from short and strenuous to long and gentle. Activities like hiking are essential to managing the physical symptoms of arthritis, but they have other benefits, too. Exercise improves sleep and helps combat the stress and depression that can accompany arthritis.

What Your Skin Says About Your Health

Your Skin: A Window to Your Health

Your skin can be a window to your underlying health, says Wake Forest University's Joseph Jorizzo, MD, one of the experts who literally wrote the book on skin signs of internal disease. Many underlying health conditions -- some very serious -- first appear as skin problems.


Butterfly Rash

A butterfly rash across the face is often the first sign of lupus. But don't jump to conclusions. "It could be rosacea, it could be contact dermatitis. Unfortunately, sometimes it is a sign of lupus," says University of Miami dermatologist Paolo Romanelli, MD. Only further tests can tell if it's really lupus.


Velvet Plaques

Velvety plaques in the neck and/or armpit suggest diabetes. This condition -- acanthosis nigricans -- could be benign or be caused by obesity. But it is very often a sign of diabetes. In rare cases acanthosis nigricans occurring in other places, such the hands or lips, may indicate an internal cancer.


Leg Plaque: Red on Edge, Gold in Center

Doctors call it necrobiosis lipoidica diabeticorum. As the name suggests, it's a distinctive sign of diabetes, but it is rare. It can first appear as a dull, reddish colored patch but then become shinier with a distinct border. Sometimes the affected skin may crack and become itchy or painful.


Itchy, Violet Bumps on Wrist

Lichen planus is a rash made up of reddish-purple, flat-topped bumps that may itch like crazy. It usually appears on the wrists or ankles, but may be in the mouth or on the lower back, neck, legs, and genitals. The cause isn't known, but if you have it, you may need to get liver tests. It could be linked to having hepatitis C.


Flesh Colored, Orange-Peel Patches on Back

Shagreen patches are flesh-colored lesions on the lower back that have the texture of an orange peel. They often occur with other skin signs: red or brown acne-like bumps spreading across the cheeks and nose; and ash-leaf spots of under-pigmented skin, most often on the trunk, that are oval at one end and pointy at the other. These are signs of a rare genetic disease called tuberous sclerosis that causes benign tumors to grow in the brain and other vital organs.


Tripe Palms

Tripe palms describes a skin condition in which the skin of the palm becomes thick and velvety-white with pronounced folds in the lines of the hand. The skin resembles boiled tripe. About 90% of cases can be linked to cancer. If only the palms are involved, it may likely be lung cancer. If tripe palms is accompanied by acanthosis nigricans, it's more likely gastric cancer.


'Wooden' Hands and Feet

First described in 1997, nephrogenic systemic fibrosis starts as a brown discoloration and indentation of the lower arms and legs. Very soon, the hands and feet become brown and like wood. Sometimes there's also a small yellow spot in the eye. Researchers only recently found that the gadolinium contrast agent used during MRI exams triggers this condition in some patients with kidney disease.


Scaly Rash on Buttocks, Red Tongue

Fortunately, necrolytic migratory erythema is pretty rare. It's a red, scaly rash, sometimes with small erosions of the skin, more often seen in elderly patients. It tends to start in the fold of the buttocks or palms but can be elsewhere on the body. A bright red, painful tongue is common. The condition usually signals a pancreatic tumor, usually a glucogenoma.

Anger, Stress May Provoke Heart Attacks

Angry Heart Attack Survivors More Than Twice as Likely to Have Another Heart Attack, Study Finds

Aug. 31, 2011 (Paris) -- Heart attack survivors who anger easily or who are often stressed out may be setting themselves up for another, potentially fatal heart attack, a new study suggests.

Over a 10-year period, more than half of heart attack survivors who had high scores on psychological tests designed to identify people with anger problems had a fatal or non-fatal heart attack, compared with fewer than one-fourth of people who had low scores.

"People with a high score on the anger scale were 2.30 times more likely to have [another heart attack] in comparison with those with a low score on the same scale," says researcher Franco Bonaguidi, DPsych, of the Institute of Clinical Physiology in Pisa, Italy.

Similarly, heart attack survivors who scored high on the stress scale were 1.90 times more likely to have another heart attack, compared with those who had low scores, he tells WebMD.

The analysis took into account known risk factors for heart disease, such as age, gender, high blood pressure, and high cholesterol.

The study involved 228 people who had had a heart attack, 200 of whom were men. Over the 10-year course of the study, 51 people had another heart attack, 28 of whom died.

The findings were presented here at the European Society of Cardiology annual meeting.

Anger a Primitive Emotion

"Anger is a primitive emotion that cannot be switched off at will," Bonaguidi says. "It can have a constructive function when it comes to overcoming obstacles and reach certain objectives."

Beyond a certain point, however, or in people who are already vulnerable to heart disease, "anger can trigger unfavorable physiological changes and can contribute to self-destructive behaviors and food and alcoholic addiction," Bonaguidi says.

The good news: People can change their behavior, he says.

American College of Cardiology Vice President John Harold, MD, a heart specialist at the University of California, Los Angeles, says the findings reflect what he sees in his own practice.

"When a heart attack patient comes in and exhibits anger or turns beet red or is stressed out, I can almost predict [that they are not going to do well] if they don't change their behavior," he tells WebMD.

Harold says he often prescribes an ocean cruise for such patients. His point is relaxation may help their health.

Other advice: If a family argument or other stressful situation is getting out of hand, walk away, Harold says. "It's just not worth it."

Sugary Drink Habit Is Widespread in U.S.

Survey Shows Teens and Young Adults Drink the Most Sugary Drinks
By Kathleen Doheny
WebMD Health News Reviewed by Laura J. Martin, MD

Aug. 31, 2011 -- Half of the U.S. population age 2 or older indulges in sugary drinks on any given day, new research finds.

"Men drink more than women, and teens and young adults drink the most," says Cynthia L. Ogden, PhD. Ogden is an epidemiologist at the CDC's National Center for Health Statistics.

The American Heart Association recommends drinking no more than 450 calories a week of sugar-sweetened drinks. That's less than three 12-ounce colas. In 2010, U.S. dietary guidelines recommended limiting the intake of both foods and beverages with added sugars.

Overall, men and boys drink an average of 175 calories from sugary drinks a day. That is more than one can of cola. Women and girls drank about 94 calories a day. That is less than one cola a day.

Sugary drink intake in the U.S. has increased over the last 30  years. Sugared beverages have been linked with weight gain, obesity, poor diet, and, in adults, type 2 diabetes.

The CDC report, "Consumption of Sugar Drinks in the United States, 2005-2008," was issued today.

Sugary Drink Intake: The Numbers

Ogden  looked at data from the 2005 to 2008 National Health and Nutrition Examination Survey (NHANES). This survey asks a sample representative of the U.S. population to tell what they ate and drank during a 24-hour period. It includes those who drink sugary drinks and those who do not.

Sugary drinks as defined for the analysis included fruit drinks, sodas, energy drinks, sports drinks, and sweetened bottled waters. Diet drinks, 100% fruit juice, sweetened teas, and flavored milks were not classified as sugary drinks in the study.

Among the other findings:

• Boys age 2 to 19 drink the most, with 70% drinking sugary drinks on any given day.


•  Adult women, overall, drank less, with 40% drinking sugary drinks on any given day.


• Teen boys averaged 273 calories a day from sugary drinks; teen girls, 171. Men 20 to 39 averaged 252 calories a day. Women in that age range averaged 138 calories.


• Five percent of the population drinks at least 567 calories from sugary drinks a day. That is more than four 12-ounce colas.

Low-income people take in more calories from sugary drinks as a percentage of daily calories than those with higher income. Non-Hispanic black and Mexican-American adults have a higher percentage of calories from sugary drinks than do white adults. One surprise, Ogden says, is that ''over half, 52%, of sugar drinks are consumed at home." She thought people would be more likely to drink them at restaurants.

She is not certain whether the intake of sugary drinks has declined since the 2010 guidelines were issued. There is new data from 2009 and 2010, she says, but it has not yet been evaluated.


Beverage Industry Reaction

Sugar-sweetened drinks ''are not driving health issues like obesity and diabetes," according to a statement issued in response to the report by Chris Gindlesperger of the American Beverage Association, an industry group.

The group points to a July 2011 study published in the American Journal of ClinicalNutrition. It showed that Americans took in nearly a quarter less added sugars in 2008 compared to 1999. That decline, according to the study, was mostly the result of people drinking less soda.

The new report did not look at these trends, but only at a snapshot in time, according to Ogden. There is not an identical NCHS report of sugared beverage intake on a given day from 2001 to 2004.

The statement by the industry group also says: "Moreover, the total number of calories from beverages that our member companies have brought to market decreased by 21 percent from 1998 to 2008, according to Beverage Marketing Corporation data."

This is due, the group says, to bringing more no-calorie and low-calorie options to market.

"Balancing calories from all foods and beverages with those burned through physical activity and exercise is essential to maintaining a balanced, active and healthy lifestyle," the group says.

Campaign to Reduce Sugar Drink Intake

A new campaign to help lovers of sugar drinks reduce their habit is being launched today by the Center for Science in the Public Interest.

It is called "Life's Sweeter with Fewer Sugary Drinks."  It will include city public health departments and organizations such as the American Heart Association and the American Diabetes Association, says Jeff Cronin, a spokesman.

The goal, he says, is to decrease intake of soda and sugary drinks down to the American Heart Association recommendation of fewer than three cans per person per week.

Among the cities signing on, he says, are Boston, Chicago, and Los Angeles. Some cities already have launched programs.

Unexpected Benefits of Depression Treatment

Better Sleep

Depression can rob you of rest by making it hard to fall asleep or by waking you up too soon. That leaves you dragging the next day. And more important, lack of sleep can make depression more severe. Treatment for depression can help improve sleep.


Better Love Life

Some antidepressants may dampen the libido. But often, the bigger roadblock to a happy love life is depression itself. One study showed that 70% of people with depression reported a loss of sexual interest while not taking medicine. Treatment may help restore your self-confidence and strengthen your emotional connection with your partner.


Pain Relief

Treatment for your depression can make you feel better emotionally and may reduce pain. That’s because depression can contribute to the discomfort of pain. Studies have found that people who have conditions like arthritis and migraines actually feel more pain -- and are more disabled by it -- if they're depressed. Seeking treatment may help provide relief.


Improved Health

If you are depressed, getting treatment may help prevent some serious diseases down the road. That’s because depression can take a toll on your body. One study found that women who were depressed had double the risk of sudden cardiac death than women who weren’t. Getting treatment may help lessen health risks.


Better Performance at Work

Depression can make it hard to hold a job. If you’re depressed, you might lose focus at work and make more mistakes. If you think depression might be affecting you at work, getting help now could head off serious problems.


Sharper Thinking and Better Memory

Feeling forgetful? Does your thinking seem fuzzy? Experts have found that depression might cause structural changes to the areas of the brain involved in memory and decision-making.
The good news is that depression treatment may prevent or reverse these changes -- clearing away the cobwebs and strengthening your recall.


Happier Home Life

Irritable and angry? Constantly snapping at your kids -- and then feeling bad about it? Getting depression treatment can help boost your mood. And that can help reduce tension around the house and improve your relationship with your family.


Healthier Lifestyle

Why does depression cause some people to gain weight? In part, it’s behavioral -- you may withdraw and become less active, or turn to food for comfort. It’s also physiological -- low levels of certain brain chemicals can trigger a craving for carbs. Getting treatment may change that while giving you the energy to exercise and eat well.


Less Chaos, More Control

When depression zaps your energy, even the most basic tasks -- like vacuuming or paying the bills -- can become impossibly hard. The more chaotic things get, the less capable you feel. Depression treatment can restore the energy you need to take control of your life and get it organized.


Lower Risk of Future Depression

People who have been depressed have a higher risk of becoming depressed again. But ongoing therapy or medication may help prevent depression from coming back. Even if it does return, treatment now will prepare you. You’ll know the early signs. You’ll know some coping skills. And you’ll know where to get help.


Stronger Ties With Friends & Family

Treating depression may improve your social life. Depression isolates people. It can sap your self-esteem, making you feel unlikeable. While therapy and medication can help restore some of that lost confidence, you still need to decide to reach out. Reconnecting to old friends when you’re depressed -- not to mention making new ones -- is hard. But it’s a crucial part of getting better.


Getting Help

Some people with depression try to wait it out, hoping it will get better on its own without treatment. That's a mistake. Studies have found that the longer depression lasts, the worse your symptoms may get and the harder it is to treat.
See your doctor. Schedule an appointment with a therapist. The sooner you get help, the better your odds for a healthy future.

Taking on Eye Allergies

Understanding Eye Allergies

Eye allergies causing red, puffy eyes? You're not alone -- millions of Americans cope with eye allergies, or allergic conjunctivitis.  A cold compress can give you a quick fix before heading out in public. But for long-term relief, you need to identify triggers and treat symptoms.


Eye Allergy Symptoms

Symptoms can include redness in the white of the eye or the inner eyelid. Other signs: itchy eyes, tearing, blurred vision, burning sensation, eyelid swelling, and sensitivity to light. Eye allergies can occur alone or with nasal allergies and the allergic skin condition eczema.The only way to know for sure if it's eye allergies is to see your doctor.


Why Allergies Make Eyes Red

Eye allergies happen when your eyes are exposed to the offending allergen -- say pet dander or pollen. Cells in your eyes called mast cells release histamine and other chemicals, causing inflammation. The result: Itchy, red, and watery allergic eyes.

Don't Rub Your Eyes

It may be tempting, but rubbing itchy eyes can make things worse. Rubbing your eyes may cause the mast cells to release more of the chemicals that caused your eyes to itch in the first place! Instead, take contact lenses out (if you wear them), avoid eye make-up, and apply cool compresses to your eyes. Wash your hands often.


Eye Allergy Cover Up Tips

Apply a hypoallergenic concealer to help hide dark circles. Don't try to cover up with heavy makeup -- it will only call attention to red, watery eyes. Instead, emphasize another feature -- wear a pretty lipstick, for example.


Eye Allergy Triggers: Pollen

If your eyes well up around Mother Nature -- and not just because of all the beauty she inspires -- you may have seasonal allergic conjunctivitis. Grass, tree, and weed pollens are the worst offenders. When pollen counts are high, stay indoors, keep your windows closed and the air conditioner on. Wear sunglasses to keep pollen out of your eyes.

Wear sunglasses to keep pollen out of your eyes.

Mop Away Allergens

If dust mites trigger your runny, watery eyes, invest in bedding and pillowcases that keep them out. Wash sheets in hot water, and try to keep the humidity levels in your home between 30 and 50%. Clean floors with a damp mop. Don't sweep, which stirs up allergens.

Eye Allergy Drops

Tear substitutes rinse the allergens out of your eye and keep eyes moist. Decongestant drops shrink blood vessels in your eyes, which decreases redness. But using them long-term can actually make symptoms worse. Both kinds of eye drops are available over the counter. People with certain conditions should not use certain types of eye drops, so ask your doctor.

Other Kinds of Eye Drops

Antihistamine eye drops reduce swelling, redness, and itching.  Some eye drops combine both antihistamines and mast cell stabilizers. These drops are available OTC and by prescription. Other prescription options may include non-steroidal anti-inflammatory drug eye drops and steroid-based eye drops.

Can Allergy Shots Help?

Allergy shots work well for eye allergies. Allergy shots (immunotherapy) help your immune system get used to the substances that cause your allergy symptoms. They are usually an option for severe allergies. Treatment can take months, and you may still need to use medicine. Are you a candidate? Talk to your doctor.

Ending Eye Allergies

From prevention and OTC artificial tears to prescription eye drops and allergy shots, there is a lot you can do to take the sting out of your eye allergies. Develop a plan of action with your doctor so today is the last day you have to put up with red, watery and itchy eyes.

Swine Flu FAQ

What Is Swine Flu?

The H1N1 flu, often called "swine flu," first appeared in the U.S. in April 2009 and quickly went on to become a pandemic, which means it was seen worldwide. H1N1 spreads between people, not pigs. The "swine flu" nickname comes from the way the virus evolved, as a mix of genes from swine, bird, and human viruses.  By August 2010, the pandemic was over, but experts believe H1H1 will continue to hang around for several flu seasons.


Swine Flu Virus

Here is a picture of the 2009 H1N1 swine flu virus, colorized and magnified.


What Are Swine Flu Symptoms?

Symptoms of H1N1 swine flu are like regular flu symptoms and include fever, cough, sore throat, body aches, headache, chills, and fatigue. Some people have reported diarrhea and vomiting associated with swine flu. Those symptoms can also be caused by many other conditions, and that means that you and your doctor can't know, just based on your symptoms, if you've got swine flu. It takes a lab test to tell whether it's swine flu or some other condition.


When Should I See My Doctor?

If you only have mild flu symptoms and you're not at high risk of severe disease, you don't need medical attention unless your illness worsens. If you are at high risk (pregnant women, young children, people with chronic medical conditions such as asthma, and elderly people), call or email your doctor at the first sign of flu-like symptoms.


When Is Swine Flu an Emergency?

Children should get urgent medical attention if they have fast breathing or trouble breathing, have bluish or gray skin color, are not drinking enough fluid, are not waking up or not interacting, have severe or persistent vomiting, are so irritable that the child doesn't want to be held, have flu-like symptoms that improve but then return with fever and a worse cough, have fever with a rash, or have fever and then have a seizure or sudden mental or behavioral change. Adults should seek urgent medical attention if they have trouble breathing or shortness of breath, pain or pressure in the chest or abdomen, sudden dizziness, confusion, severe or persistent vomiting, or flu-like symptoms that improve, but then come back with worsening fever or cough.


How Does Swine Flu Spread?

The 2009 H1N1 swine flu virus spreads just like regular flu. You could pick up germs directly from an infected person, or by touching an object they recently touched, and then touching your eyes, mouth, or nose, delivering their germs for your own infection. That's why you should make a habit of washing your hands, even when you're not ill. Flu germs can start spreading up to a day before symptoms start, and for up to seven days after getting sick, according to the CDC.


How Is Swine Flu Treated?

The 2009 H1N1 swine flu virus is sensitive to the antiviral drugs Tamiflu and Relenza. But not everyone needs those drugs. Most people who have come down with swine flu have recovered without treatment. The CDC has recommended prioritizing antiviral drugs for people with more severe flu illness and people in high-risk groups.


Is There a Swine Flu Vaccine?

Yes. WebMD Senior Writer Dan DeNoon, pictured here, took part in a trial of the H1N1 vaccine. Swine flu came on the scene too late in 2009 to be included in the regular flu shot that people can get beginning in October each year. For winter 2010-2011, the H1N1 vaccine was included in the seasonal flu vaccine. It comes as a shot or nasal spray.


How Severe Is Swine Flu?

The severity of cases has varied widely, from mild cases to fatalities. Most U.S. cases have been mild, but there have been a number of deaths and hospitalizations. Flu viruses can change, and it's impossible to know whether the 2009 H1N1 swine flu virus will become more deadly. But so far, this particular virus hasn't changed much since it first appeared.


How can I prevent swine flu infection?

The CDC recommends taking these steps:

• Wash your hands regularly with soap and water, especially after coughing or sneezing. Or, use an alcohol-based hand cleaner.


• Avoid close contact with sick people.


• Avoid touching your mouth, nose, or eyes.


• Got flu symptoms? Stay home, and when you cough or sneeze, cover your mouth and nose with a tissue. Afterward, throw the tissue in the trash and wash your hands.

What Else Should I Be Doing?

Keep informed of what's going on in your community. Your state and local health departments will have important information on how your area is handling flu.

Can I Still Eat Pork?

The nickname "swine flu" initially caused a lot of confusion and some worries about what was safe to eat. The answer is "yes," pork is safe to eat. You can't get swine flu by eating pork, bacon, or other foods that came from pigs.
