Long QT syndrome (LQTS) is a heart rhythm condition that can potentially cause fast, chaotic heartbeats. These rapid heartbeats might trigger a sudden fainting spell or seizure. In some cases, the heart can beat erratically for so long that it causes sudden death.

You can have a genetic mutation that puts you at risk of being born with congenital long QT syndrome. In addition, certain medications, imbalances of the body's salts and minerals (electrolyte abnormalities), and medical conditions might cause acquired long QT syndrome.

Long QT syndrome is treatable. You might need to take medications to prevent an erratic heart rhythm. In some cases, treatment for long QT syndrome involves surgery or an implantable device.

You'll also need to avoid certain medications that could trigger your long QT syndrome. After treatment, you likely can live and thrive, even with this condition. You may be able to continue being active in recreational — and even competitive — sports.

Q fever, also called query fever, is a bacterial infection caused by the bacteria Coxiella burnetii. The bacteria are most commonly found in cattle, sheep, and goats around the world. Humans typically get Q fever when they breathe in dust that was contaminated by infected animals. Farmers, veterinarians, and people who work with these animals in labs are at the highest risk of being infected. The highest amounts of bacteria are found in the "birth products" (placenta, amniotic fluid) of infected animals. The disease may cause mild symptoms similar to the flu. However, many people have no symptoms at all. Mild forms of the disease may clear up in a few weeks without any treatment.

In rare cases, a more serious form of disease develops if the infection is chronic, which means it persists for six months (and there are some case reports indicating that it may persist for more than six months). A more serious form also can develop if the infection is recurrent, which means it comes back. People with heart valve problems or weak immune systems are at the highest risk of developing these types of Q fever. Chronic Q fever is very serious because it can damage a person’s vital organs, including the:

heart

liver

brain

lungs

More severe or chronic forms of Q fever can be treated with antibiotics. Those at risk for Q fever can prevent the disease by disinfecting contaminated areas and washing their hands thoroughly.

Frequent urination is a condition defined when the need to urinate is felt several times an hour, caused by the false impression of once again having a full bladder. The quantity of urine passed during the day is not, however, larger, as the urinations are very small in volume. Daytime frequent urination is assessed based on the frequency with which the patient has to go to the toilet. This false impression is most of the time due to an irritation in one of the urinary organs. There can be many different underlying causes of this irritation, such as inflammation of the bladder, called cystitis or more commonly urinary infection, or prostatitis, which is an inflammation or benign swelling of the prostate in men.

Mosquito bites are the itchy bumps that appear after mosquitoes use their mouthparts to puncture your skin and feed on your blood. The bump usually clears up on its own in a few days. Occasionally a mosquito bite causes a large area of swelling, soreness and redness. This type of reaction, most common in children, is sometimes referred to as skeeter syndrome.

Bites from mosquitoes carrying certain viruses or parasites can cause severe illness. Infected mosquitoes in many parts of the world transmit West Nile virus to humans. Other mosquito-borne infections include yellow fever, malaria and some types of brain infection (encephalitis).

You eat organic almost exclusively and try to steer clear of anything made of plastic (especially The 4 Most Dangerous Types Of Plastic). But there’s just one unhealthy habit you can’t shake: smoking.

You may even tell yourself that the “natural” tobacco you use isn’t as bad for you, but even without the additives found in common cigarette brands, tobacco smoke contains a panoply of dangerous chemicals such as carbon monoxide and dozens of other known carcinogens.
