Travel Health Advice


Suffering from traveller's tummy is a fear many people have when visiting a foreign place, especially a developing county. Research shows that one in three people may be genetically susceptible to traveler’s diarrhea, caused by an E coli bacteria. “In the future, we might be able to do a quick test to determine if someone is susceptible and if so, the logical thing would be to give them antibiotics before they travel, to prevent them from getting sick,” says Dr. Herbert DuPont, co-author of the University of Texas study.

In the meantime, the ‘boil it, peel it, cook it or forget it’ rule is sensible for visits to developing countries. To further guard against poor restaurant hygiene, Dr. David Shlim, medical director of Jackson Hole Travel and Tropical Medicine in Wyoming suggests ordering only freshly cooked dishes (like meat), avoiding reheated items such as lasagna or quiche and carrying a quick-acting antibiotic such as ciprofloxacin.

Heart Smart Travel

If you sit in a cramped airline, bus, train or car seat for hours at a time you may be at risk for a heart attack says a study from the University of Innsbruck. Comparing trips by plane and bus, the research showed that tight seating (not high altitude or low oxygen pressure) prompts coagulation of the blood and can make travelers prone to deep vein thrombosis (DVT)— a blood clot in the leg which can lodge in an artery and block blood going to the heart. To help prevent DVT, drink plenty of non-alcoholic fluids and move your “ankles and legs every hour to work those calf muscles and get them pumping blood,” advises Dr. Bo Eklof, an expert on travelers’ thrombosis with the University of Hawaii, Honolulu. He also suggests wearing support hose and for those at high risk (recent surgery or seriously ill), getting a blood thinner injection before your trip.

The Swine Flu crisis has brought awareness of travel health risks to the fore. However, findings of a survey by the European Travel Health Advisory Board (ETHAB) a few years ago revealed that the majority of travelers in the Asia-Pacific and U.S. did not seek travel health advice before going to an area with a risk for infectious disease. The survey reported that of 8,000 people questioned, the majority hadn’t had a hepatitis vaccine while 40 percent of Americans and 97 percent of the Asia-Pacific respondents did not carry anti-malarial medication. Dr. Francesco Castelli, a member of ETHAB, noted there was a “60 to 70 percent chance that a traveler will develop a health complaint on a trip to developing countries.”

Stye - Symptoms and Treatment

A stye is an infection, typically a bacterial infection, which causes a painful red lump either on the edge or inside of the eyelid. Bacteria grow at the root of an eyelash follicle or inside an oil gland. The bacteria can be a result of poor hygiene, touching the eyes with unwashed hands or chronic inflammation. The stye resembles a pimple or a boil and is usually filled with pus. A stye does not pose a risk to vision and most often heals without treatment within a week. However, a stye may require treatment with a doctor if the infection does not resolve with at-home remedies. Symptoms of a Stye A stye is not usually hard to spot. Not only does a red lump form on either the top or bottom eyelid, but pain is also an immediate symptom of the condition. Typical symptoms of a stye include: red lump on the eyelid similar to a pimple watering of the eye eyelid pain and swelling clear or yellow fluid collecting in the stye A normal stye will come to a head in approximately three to

Safeguard the Achilles

One of the most painful tendon injuries is Achilles. But there are also ways to avoid these injuries. Here are some of them: You’ll feel a burning and piercing in the tendon above your heel and it can even make a crackling sound when you move it. Any higher up your calf and it’s more likely that you’ve strained or pulled a muscle. Rupturing your Achilles tendon is a exceptionally painful experience and you’ll know when you’ve done it. Your Achilles tendon connects your calf muscles to your heel bone and is made of thousands of individual fibers of collagen. Restricted blood flow to this area slows repair and pain will worsen if you keep training . Four important factors in healing the Achilles are: rest, ice, compression and elevation. If your tendon is harmed take a break from all weight bearing sport (except swimming) for at least 2 weeks. You can recover from mild injury in a couple of weeks but a severe one can take 5 months. In order to prevent Achilles injury in

Causes of Easy Bruising: Reasons Why People Bruise Easily

Bruising , a reddish or purple discoloration under the skin, most often results from trauma to the small blood vessels, called capillaries, but can also occur spontaneously. How and Why Bruises Occur Blood leaks out of the capillaries and accumulates under the skin, gradually absorbing over several days. Bruising most often occurs because people run into objects or experience other trauma. Most bruising is easily explained, but frequent bruising that occurs without obvious cause needs prompt investigation, since several serious diseases can cause bruising. In general, women bruise more easily than men. How Aging Increases the Risk of Easy Bruising Bruising increases as people age for several reasons. Skin thins as people age and the capillaries become more fragile. The layer of fat that cushions blood vessels and protects them from injury becomes thinner as well. Older people often take medications and supplements that thin the blood and contribute to easy bruising. Visi
