Height Loss with Aging

The bones of your spine are separated by pads called discs. As you age, these discs dry out and become smaller. However, regular exercise compresses and relaxes these discs as you move up and down. This helps to keep the discs from shrinking and maintains your height.

New Drug May Slow Down Alzheimer’s Disease

A study of 856 patients with a mild, early form of Alzheimer’s disease, found that a new drug called BAN2401 may reduce the amount of amyloid plaques in the brains of people with Alzheimer's disease. The drug reduced the amount of Beta-amyloid in sticky plaques that form around nerves in the brain to prevent messages being sent from one nerve to another.

Sleep Problems Associated with Increased Stroke Risk

A study of 1,799 people, who had suffered and survived strokes at the average age of 62, found that stroke risk is markedly increased by sleep disturbance symptoms, poor sleep quality, napping for long periods, and sleep apnea symptoms (Neurology, May 23, 2023;100(21): e2191–e2203). The stroke survivors were compared to age-matched people who had not had a stroke and the results were adjusted for smoking, physical activity, depression, and alcohol intake.

Male Infertility

Infection is the most common cause of male infertility and that standard tests for infertility often do not find the infection. When evaluating a male for infertility, doctors check sperm count and sperm mobility. If a man's ejaculate contains fewer than 50 million sperm, he is infertile, and the most common cause of reduced sperm count is infection.

Hepatitis C

If you are tired, feel sick and have muscle and joint pains, part of your evaluation should include a blood test for hepatitis C, even if all liver function tests are normal.

Preventing Alzheimer’s Disease

A study from Brown University Medical School showed that Alzheimer’s disease may be another form of diabetes, and all the recommendations for avoiding diabetes may also protect your memory.

Exercise Can Help to Treat (and Prevent) Cancer

Exercise is now recommended as part of the treatment for cancer by the American College of Sports Medicine, the American Society of Clinical Oncology, the National Comprehensive Cancer Network, the American Cancer Society, the Oncology Nursing Society, the Commission on Cancer and the Cancer Foundation for Life.

Radon

After cigarette smoke, radon gas is the second leading cause of lung cancer, causing more than 15,000 deaths each year. Radon-222 is a colorless, odorless gas that forms from the decay of naturally occurring uranium-238. Since U-238 occurs in soil and rock throughout the world, radon gas seeps into homes through the soil.

Eating Mammal Meat is Associated with Increased Risk for Gastro-Intestinal Cancers

Researchers at the Centre for Ecological Research in Hungary analyzed the death records for 110,148 animals from 191 mammal species that died in zoos and found that carnivorous mammals were much more likely to die of cancer than mammals that rarely or never eat animals. Humans are mammals, so we might expect to see similar results in studies of human diets.

Exercise lowers homocysteine

A regular exercise program helps to lower high blood levels of homocysteine, according to a study from multiple medical centers (European Journal of Applied Physiology, November 2006). High blood levels of homocysteine increase your risk for heart attacks, but at this time, nobody knows why. More than 200 papers show high blood levels of...

Protein Found in Belly Fat Increases Cancer Risk

Visceral fat (the fat inside your belly and around organs) makes a protein called fibroblast growth factor-2 (FGF2) in much larger amounts than fat underneath your skin does. FGF2 can convert normal cells into cancerous ones.

Colon Cancer and Bacteria

Researchers at Harvard University and VHIO cancer Institute in Barcelona report that colon cancer may be caused by a specific bacteria, Fusobacterium nucleatum. I believe this is breakthrough research that could lead to a potential cure for colon cancer and a Nobel Prize.

New Studies on Fatty Liver

A liver full of fat can be caused by anything that damages the liver. Doctors used to separate liver damage into that caused by alcohol and that not caused by alcohol (non-alcoholic fatty liver disease or NAFLD). Now we know that a liver damaged by excess alcohol has the same harmful consequences as a...

Foot Odor

Do you know why you should wear socks? It's to keep your feet and shoes from smelling. Foot odor is caused by bacteria or fungi rotting old skin. Your skin turns over every 28 days. A new cell starts on the bottom layer of skin, then another skin cell forms underneath it. The process continues...

Impotence is a Major Risk Factor for Heart Attacks

A review of published studies shows that the world-wide incidence of inability to achieve an erection varies widely from three percent to 76.5 percent, and the geographical incidence of impotence is associated with all the same risk factors as those for heart attacks, dementia and having an enlarged prostate (BJU International, July 3, 2019)....

Angioplasty’s Questionable Results

Angioplasty may not boost survival for heart disease patients. A 15-year follow-up shows that those who have had angioplasties do not live longer than those who received just medication. This supports other studies that have shown that some angioplasties should not have been done

Brain Tissue Loss Linked to Diabetes

Research shows that the longer a patient has diabetes, the smaller his brain, particularly in the gray matter that interprets and directs muscle control, seeing and hearing, memory, emotions, speech, decision-making and self-control. Diabetics lose brain size more than twice as rapidly as non-diabetics. The longer a person has diabetes, the more likely he is to suffer dementia.

Healthful Diet Helps to Prevent Colon Cancer

A study published this week shows that vegetarians who eat fish have a 43 percent reduced risk for developing colon cancer, compared to people who eat meat (JAMA Internal Medicine, March 9, 2015). Researchers analyzed the diets of nearly 78,000 men and women. During an average seven years of follow-up, they identified 380 cases...

Aspirin to Prevent Colon Cancer?

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...

How Excess Fat Can Spread Cancer

People who have cancer and are also overweight are at increased risk for having the cancer spread through their bodies. A new study shows how excess weight may spread cancer cells through the body.

How Sugar-Added Foods and Drinks Increase Risk for Heart Disease

Researchers followed more than 110,000 people for nine years and found that the more free sugar a person takes in, the greater the risk for heart disease. Each five percent increase in free sugar intake in a participant's daily diet resulted in a six percent higher risk of heart disease and a 10 percent higher risk of stroke. Furthermore, a higher fiber intake and replacing refined grain starch and free sugars with whole grains and non-free sugars appeared to help protect against heart attacks.

Can Your Cholesterol be Too Low?

Almost everyone agrees that having total blood cholesterol levels above 250 is likely to shorten your life and markedly increases your chances of suffering a heart attack, unless you have a very high HDL (which is good). Other studies also show that people with very low cholesterol are at increased risk for cancer of the stomach, esophagus, liver and colon, but it looks like the incubating cancers cause the low cholesterol, rather than a low cholesterol causing the cancers.

Fatty Liver Can Cause Diabetes, Heart Attacks and Cancers

More than 80 million North Americans suffer from a fatty liver and many do not know that they have it because most people with a fatty liver have normal liver function blood tests in the early stages of the disease. The American Association of Clinical Endocrinology, supported by the American Association for the Study of Liver Diseases, has issued guidelines for diagnosing and treating a fatty liver.

Agent Orange Does Not Cause Diabetes

In April 2000, a study from the Air Force was widely reported in newspapers to have shown that agent orange causes diabetes. Only Gina Kolata of the New York Times wasn't fooled (NYT, April 20, 2000).

Varicose Veins Helped by Exercise

A regular exercise program may be the most effective treatment for varicose veins. Veins are supposed to contain valves that keep blood from backing up. When the valves cannot close properly, veins become varicose, blood backs up and causes the veins to widen and look like blue snakes underneath the skin. Since varicose veins...

Grapefruit Juice Effects on Drugs

Several reports show that taking certain medications with grapefruit juice can cause problems by markedly increasing absorption of the medication. Many drugs are broken down in your intestines by an enzyme called cytochrome P450 that is normally there, so these drugs have to be given in higher concentrations than normal to achieve adequate blood levels....

LDL Cholesterol Can Be Too Low

A study of more than 100,000 healthy Chinese citizens followed for nine years showed that having very low levels of LDL cholesterol (<70 mg/dl) is associated with increased risk for bleeding into the brain, and the lower the LDL, the greater the risk (Neurology, July 2, 2019). Normal blood levels of LDL cholesterol are...

Intense Exercisers Have More Plaques but Fewer Heart Attacks

The MARC-2 study followed 291 older men for 6.3 years with a test called Coronary Artery Calcification (CAC), and found that the amount of calcium in the arteries leading to the heart increased most in men who exercised at the highest intensity, even more than those who exercised the most. The authors said this showed that intense exercise increases the amount of plaques in arteries, which may be true. However, they would then have to explain why intense exercisers are far less likely to suffer heart attacks than non-exercisers

Smoking Increases Cervical Cancer Risk

Cervical cancer is a venereal disease caused by the human papilloma virus called HPV. Nineteen different strains of HPV have been associated with cervical cancer. HPV-16 is the most carcinogenic. As solid cancers grow, they produce angiogenesis factors that increase blood flow to them to supply nutrients and energy. Tobacco contains nicotine, a potent...

The Hidden Cause of Many Heart Attacks

More than 40 percent of people who have had heart attacks are diabetic and these patients are the ones who are most likely to die from their heart attacks (Lancet, 2002; 359: 2140-44). Three tests are commonly used to diagnose diabetes: fasting blood sugar, blood sugar level two hours after eating, and HbA1c, a measurement of how much sugar is attached to cells.
