Chemotherapy and radiation used to treat cancers can help to prolong lives, but these treatments can also increase heart attack risk. The American Heart Association recently recommended that patients receiving chemotherapy or radiation to treat breast cancers should be made aware that these treatments increase heart attack risk and that all people being treated for cancer should be on a lifestyle program to prevent heart attacks.
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
People who run or walk regularly have healthier and stronger spinal discs than non-exercisers do (Scientific Reports 7, April 19, 2017). This is very reassuring because some doctors tell patients with back pain not to run because they think that the jarring of the foot striking the ground will damage discs and injure backs,.
Research has shown that most cases of swollen testicles do not need to be corrected by surgery. Swollen, painless testicles are usually caused by varicoceles, large veins full of blood on the outside of the testicles; or hydroceles, a sac of fluid around the testicles. Less common causes include infection or a tumor.
Today, more than 29 million people in North America are diagnosed as being diabetic, another 86 million have pre-diabetes, and most diabetics have not even been diagnosed. More than 88 percent of North American adults have their blood sugar levels rise too high after they eat.
Your liver is the organ that picks up breakdown products of your own metabolism and removes them from your body. The promoters of liver-detoxifying supplements tell you that their products "support healthy liver function" and help it do its job better.
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.
A study that followed 13,000 men from 1971 to 2009 shows that men who keep a high level of fitness from their forties onward have a one third lower risk overall of dying from certain cancers after age 65 (JAMA Oncology, March 27, 2015). Fitness was measured by their ability to keep on running...
Many doctors are missing a chance to save the lives of their patients by not ordering a blood sugar level one hour after eating a meal. Having a normal fasting blood sugar (<100 mg/dl) does not rule out diabetes.
Researchers followed 63,257 Chinese adults aged 45–74 for an average of 10.9 years and found that eating red meat was associated with increased risk for developing diabetes. The authors suggest that it may be the iron in meat that could cause diabetes.
Millions of people take over-the-counter NSAID pain medicines when they have a headache, fever, chills, joint pain or various other aches and pains. A new study shows that NSAIDs are associated with increased risk for heart attacks.
In the biggest advance in knowledge about the prevention of heart attacks since the discovery of statins, researchers at Harvard Medical School have shown that blocking inflammation helps to prevent heart attacks and cancers.
The U.S. Food and Drug Administration (FDA) has announced that it will ban triclosan and 18 other antibacterial chemicals in soaps and liquid hand or body wash products because they are ineffective and potentially harmful. The banned chemicals are also found in hand sanitizers, detergents, deodorants, antiperspirants, lotions, creams, toothpastes, dishwashing liquids, shampoos, mouth washes, shaving cream, after-shave lotions, hair conditioners, foot odor products, cleaning supplies, pesticides, kitchen utensils, toys, bedding, socks, trash bags and even baby pacifiers, but the FDA ban does not affect these products.
One in three North American adults have to get up to urinate more than twice a night, and a study presented at the European Society of Urology shows that the most common cause may be taking in too much salt.
A review of the world's literature shows that high-intensity exercise, particularly interval training, causes greater reduction in HbA1c in diabetics than less intense exercise. HbA1c measures cell damage from high blood sugar levels. Many studies show that increasing exercise intensity controls blood sugar in diabetics more effectively than just increasing the duration of exercise.
People who take aspirin are at reduced risk for colon cancer, unless they are among the four percent of North Americans who have a genetic susceptibility for colon cancer (JAMA, March 17, 2015;313(11):1133-1142). Colon cancer is the second leading cause of cancer death in the United States (after lung cancer), with 1,162,426 people living...
Debilitating constipation affects 16 percent of North Americans and 33 percent of those older than 60. This epidemic of constipation is largely caused by a food industry that produces mostly ultra-processed foods that contain little or no fiber. People keep looking for constipation cures in a pill, but it is usually curable just with simple lifestyle changes.
Having high blood levels of cholesterol increaes your chances of getting a heart attack, but your blood cholesterol level is influenced far more by how many calories you eat than by how much cholesterol is in the food you eat.
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.
Many studies show that eating meat every day is associated with increased risk for heart disease, but until now we have had little data about the effects of eating meat less often than that. A new study followed 29,682 participants, average age 53.7, for 30 years and found that eating two servings per week of mammal meat or processed meat was associated with a seven percent increased risk of heart disease.
The majority of heart attacks are caused by unhealthful lifestyles, not by genetic defects. Statins remain the major choice of preventative drug, but everyone should realize that many studies show that lifestyle changes are probably more effective than statins in preventing heart attacks.
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.
Very exciting research from Princeton University explains how taking in sugared drinks and any sugar added to foods (not in whole fruits and vegetables) can cause diabetes. The authors of this study show that fructose is converted to glucose primarily in the intestines, and not in the liver as scientists thought previously.
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.
More than 90 percent of North Americans will develop high blood pressure. A new study shows that a diet high in potassium appears to protect teenagers from high blood pressure in adulthood, while a low-salt diet has no effect (JAMA Pediatr, June 2015;169(6):560-568). A high-potassium and low-salt diet is achieved by eating mostly plants,...
