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.
Are you concerned about getting one of the new COVID-19 vaccines as soon as they are approved? We have no long-term safety information because no one has more than 10 months of experience with this disease. However, we do have decades of experience with other vaccines.
This winter is expected to be a severe flu season. Flu virus is headed here from the southern hemisphere, and Australia already has a very severe flu season. Only 49 percent of North Americans plan to get a flu shot during the 2022-2023 flu season, according to a survey by the National Foundation for Infectious Diseases (NFID).
Heart attacks and strokes cause 50 percent of the deaths in North America today, yet many people are not adopting the lifestyle changes needed to prevent the factors that cause them: inflammation and clotting. A new study from the University of Michigan shows how important inflammation is as a cause of heart attacks and strokes.
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.
You cannot be poisoned by vitamin D through sun exposure or diet alone, but vitamin D poisoning can occur when people take high-dose supplements for an extended time. Excess vitamin D can cause blood calcium levels to rise and after several months of having high blood calcium levels and having no symptoms at all, you can develop kidney failure and not even know it.
Dry skin on any part of the body can be annoying and can cause flaking and cracking, redness due to scratching, and unsightly patches of thick or hard skin. When dry skin occurs on the feet, the symptoms are magnified due to wearing shoes, the stretching of the skin on the feet with every step . . .
The only way that the pandemic will end is when a sufficient percentage of people become immune to COVID-19, most by being vaccinated plus a lesser number of people who have been infected with the virus and recovered. This is called herd immunity. Researchers tell us that in the U.S., the pandemic will not end until about 40 to 70 percent of the population is immune.
A hammertoe is a general name for a toe that is bent. Hammertoes are caused by genetics, arthritis, poor-fitting shoes, or feet that are either excessively high-arched or flat. You can't change genetics, and in most cases, you can't prevent arthritis.
I have said repeatedly that surgery to trim attached cartilage in the knee is usually worthless. I have seen many patients who have had cartilage removed by surgeons for an average charge of $5000, and then they must have a knee replacement several years later.
Recent studies show that having low levels of vitamin D is associated with increased risk for high blood pressure, heart disease, and severe consequences of COVID-19. Researchers in Australia collected data prospectively from 295,788 participants, and found that having low blood levels of vitamin D is associated with increased risk for high blood pressure and heart disease. (Normal blood levels of hydroxy-vitamin D are considered to be above 30 ng/mL).
More than six million North Americans suffer from dementia, which affects three percent of people age 65-74, 17 percent of age 75-84, and 32 percent of those age 85 and older. Anything that damages brain cells can cause dementia and many of the causes are treatable.
A very important new study of 27,599 adults, average age 47-50, showed that almost 15 percent of North American adults and almost 19 percent of those with high blood pressure take medications that can raise blood pressure. The blood-pressure-raising medicines taken most frequently were antidepressants, NSAIDs, steroids, and estrogens.
A huge study from Korea confirms that people with Metabolic Syndrome are at increased risk for heart attacks, and that when they correct some or all of the components of Metabolic Syndrome, their risk for a heart attack goes down dramatically.
Your blood pressure usually rises as soon as you start to exercise and drops a little bit while you exercise at the same intensity. However, as you continue to increase the intensity of exercise, your blood pressure usually rises higher and higher.
In small studies in animals and humans, vinegar has been shown to reduce the rise in blood sugar and insulin that normally occurs after a meal. However, I cannot find any large studies to show that vinegar is an effective treatment for diabetes.
The CARDIA Study shows that having certain types of bacteria in your colon is associated with having high blood pressure, and that you can lower blood pressure by improving the proportion of healthful to unhealthful bacteria in your colon. Lifestyle changes may be more important than drugs in treating high blood pressure.
Nearly fifty percent of people over 85 suffer from symptoms of dementia of which Alzheimer's disease, a progressive loss of brain cells, is the most common form. The second most common type of dementia comes from repeated strokes. This month researchers offer strong evidence that Alzheimer's disease may be started by an infection.
A recent study from respected researchers at Johns Hopkins claims that two-thirds of adult cancers are caused by random DNA mutations in your cells, and far fewer cancers are caused by genetics, lifestyle or exposure to cancer-causing agents.
More than 30 million adults in North America suffer from diabetes and another 85 million have pre-diabetes that is likely to become full-blown diabetes within five years. Research papers published this month suggest that people who are diabetic or likely to become diabetic should eat a very large amount of plant fiber and restrict animal products, particularly red meat and processed meats.
Medical researchers agree that exercising into old age helps to prevent heart attacks, strokes and cancers and prolongs lives, but one report shows that sometimes competing in endurance sports may cause atrial fibrillation.
Having high blood levels of the bad LDL cholesterol (>100 mg/dL) is associated with increased risk for heart attacks and premature death, and is the single most important predictor of forming plaques in your arteries. Many experts recommend lowering elevated LDL levels to 70 mg/dL in people who are at increased risk for heart attacks.
On November 10, 2018, heart specialists presented the latest recommendations for preventing heart attacks from the American College of Cardiology and the American Heart Association: Treat all of their patients with recommendations for heart-attack-preventing lifestyle changes, and Treat all patients with significant heart attack risk factors with medications that lower blood levels of the bad LDL cholesterol.
I had my appendix removed when I was a child because the doctor told my mother it was a useless organ that might someday burst and cause horrible problems. After generations of children had their appendices removed for no reason, researchers have found that perhaps it may have an important function.
Edges of toenails that press into the flesh can cause pain, swelling, redness, and even infection. Your skin may start to grow over the ingrown toenail. Treatments include special chemicals, lasers, and various ways to remove the edge of the nail that presses into the skin.
A study from Columbia Medical School shows that a high fiber diet that is low in sugar and saturated fat can help you to fall sleep faster and sleep deeper at night. A single day of increased sugar and fat and decreased fiber intake can interfere with your sleep that night.
Having a high (>100 mg/dL) bad LDL cholesterol or a low (<40) good HDL cholesterol has long been associated with increased risk for heart attacks. However, new studies show that you can form plaques and be at risk for a heart attack even if your bad LDL cholesterol is as low as 50.
