Up to 60 percent of North American adults suffer from night-time leg cramps, a sudden painful contraction usually of the calf muscles that can last from a few seconds up to 10 minutes or more. Doctors do not know what causes most cases of leg cramps, but usually they are not caused by dehydration or lack of minerals.
CAUTION: The news media often reports on articles from the websites of scientific journals that have not yet been peer reviewed by other doctors. It has become common practice to "pre-publish" studies or press releases online before they have been fully reviewed, and many of these reports are sent out by companies with a lot of money at stake.
People who develop frequent infections are at increased risk for developing cancer later on. Japanese researchers checked 2,354 patients suffering from malignant cancers and found that compared to those who did not develop cancer, cancer sufferers were at significantly increased risk for suffering infections such as influenza, pneumonia, hepatitis, or gastroenteritis in the six years before they were diagnosed with cancer
A review of 4,103 patients found that obesity and its resultant inflammation, heart disease and diabetes are the most common conditions found in patients requiring hospitalization with COVID-19.
We have no drugs yet proven to prevent or treat COVID-19, although some drugs appear promising, as do transfusions of blood donated by people who have recovered and are now immune. The virus is spread from one person to another; it has not been shown to be spread from animals or food.
Federal guidelines now require most Americans to avoid non-essential travel, non-essential work, eating at bars and restaurants, and gathering in groups of more than 10, at least through April 30, 2020. Many states and local governments have stricter directives that take precedence over the federal guidelines.
The World Health Organization (WHO) gave the new coronavirus the name "COVID-19" on February 11, 2020, and declared it a pandemic on March 10, 2020. COVID-19 is not more severe than many flu viruses. However, it is incredibly contagious.
As of 3/27/20, we have no drugs that have been proven to be effective for shortening the course of COVID-19 infections. Several possible drugs are currently being tested in the midst of the massive outbreak in New York City.
Today there are no drugs that have been proven to treat the coronavirus, COVID-19, but a study from China showed that the inexpensive anti-malarial drug, Chloroquine phosphate, was safe and effective in shortening the course and decreasing symptoms in patients suffering from COVID-19 pneumonia.
Lack of vitamin D can cause weak bones that break easily, bone pain, and muscle weakness, and may increase risk for diabetes, high blood pressure, certain cancers, nerve damage and autoimmune conditions such as multiple sclerosis. However, taking very high doses (>3000 IU/day) of vitamin D can harm you.
In North America, more than 40 percent of cancers and cancer deaths from 26 different cancers are associated with lifestyle factors such as excess weight, a faulty diet or lack of exercise.
Compared to non-drinkers, people who take one or two drinks per day for one year are at increased risk for cancer, and drinking even one glass of wine a day raises the risk of cancer of the throat, esophagus, liver, colon, rectum or breast.
You should never suffer from frostbite: painful freezing that can cause permanent loss of skin, and can be followed by loss of fingers, ears, toes, or even arms and legs. You get plenty of warning before your skin starts to freeze. First your fingers feel cold and then your skin starts to burn or itch.
If your fingers turn white and start to hurt when you are out in the cold, you may have a condition called Raynaud’s phenomenon. When your body temperature starts to drop, your brain sends signals along nerves to shut blood flow to your hands and the skin turns white.
Lack of vitamin D may change the colon bacteria to an overabundance of harmful bacteria to cause inflammation that increases risk for autoimmune diseases such as inflammatory bowel disease, multiple sclerosis, diabetes, lupus and some types of arthritis.
2019 Nobel Prize honors the discovery of how your body responds when you can't meet your needs for oxygen. Their groundbreaking research is now being used to treat certain cancers, strokes, infections, anemia, heart attack risks, and some eye diseases that can cause blindness.
Your body uses inflammation to protect you from invading germs and to heal injuries. When a germ gets into your body, you make cells and proteins to kill that germ. As soon as the germ is gone, your immune system is supposed to dampen down and stop making large amounts of these cells and antibodies.
A study of more than two million people showed that being overweight markedly increases risk for at least nine different cancers in men (bladder, colorectum, gallbladder, kidney, liver, lung, lymphatic system, pancreas, stomach) and eleven cancers in women (gallbladder, kidney, liver, lung, lymphatic system, ovaries, pancreas, stomach, uterus, cervix, and endometrium).
A study of 58,769 patients over 55 years of age diagnosed with dementia and 225,574 people of the same age without dementia found a 50 percent increased risk of dementia among people who used a strong anticholinergic drug daily for about three years within the 10-year study period
It only takes one injection each year to protect you from the flu. The vaccine is very safe and cannot cause disease because it is made from killed virus. The most common side effect is a sore arm from the injection. Some people may suffer a few hours of fever, muscle pain, and chills.
At last, the U.S. Food and Drug Administration (FDA) is proposing new rules on sunscreen safety. Finalizing these rules and actually making changes on the regulation or labeling of sunscreens will take time, so I advise you to follow their recommendations now by reading the labels and avoiding those products with ingredients that are unlikely to be safe or may be found unsafe. Here are the proposed rules.
More than 30 percent of North Americans over the age of 85 suffer from dementia. A study presented recently at the International Stroke Conference 2019 shows that having harmful bacteria in your colon increases risk for dementia.
For many years I have offered my opinion that sunlight provides benefits that are not gained just from taking vitamin D pills. Recent research is confirming that opinion, and many scientists now believe that low vitamin D blood levels are only a marker for not getting enough sunlight.
More than 1.3 million North Americans have had colorectal cancer, a disease associated with behaviors that encourage cancer-causing bacteria to thrive in your colon. Colon cancer is linked to lifestyle factors that increase inflammation risk: an unhealthful diet, lack of exercise, excess weight, smoking, and alcohol consumption.
Dementia means loss of brain function, and your chance of having dementia increases with age. Doctors can now predict increased risk for developing dementia by ordering an MRI which can show decreased volume of grey matter in the brain.
Extensive evidence shows that aging is associated with, and partially caused by, the accumulation of "senescent cells" in your body. Recent animal studies have shown that it is possible to extend the lives of animals by reducing the numbers of senescent cells, even if treatment is started late in life.
Results from the huge EPIC study (European Prospective Investigation into Cancer and Nutrition) confirm that eating a lot of junk food increases risk for many cancers. Researchers in Paris followed 471,495 adults in 10 European countries for an average of 15.3 years, and the participants developed 49,794 cancers. The participants' diets were scored using the British Food Standards Agency's Nutrient Profiling System (FSAm-NPS), which ranks foods according to their healthful and harmful components. Those who ate more of the harmful and less of the healthful food components were at significantly greater risk for developing cancers, particularly cancers of the breast, prostate, colon-rectum, mouth, throat, esophagus, stomach, lung and liver.
You can reduce your risk for suffering from dementia by up to 70 percent when you follow the same healthful habits that help to prevent heart attacks. A study of 6,600 people over 65, followed for 8.5 years, found that each lifestyle risk factor for heart attacks is also a risk factor for dementia, and that correcting each heart attack risk factor reduces risk for dementia.
