With aging, many people develop dark spots on their skin, particularly in the sun-exposed areas of the face and back of the hands. Others develop dark spots after pregnancy or trauma, such as an abrasion, insect bite or cut.
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.
The risk of developing dementia doubles every five years after age 65, until by age 85 almost 50 percent of North Americans suffer some degree of dementia. Finnish researchers showed that they were able to slow the onset of dementia in people at high risk with a lifestyle program.
All people smell when they don't bathe often enough. Sweat doesn't smell when it first reaches your skin. The odor comes only after bacteria or fungi on the skin's surface break down the fat in sweat to form chemicals that smell. Most sweat glands produce sweat that contains no fat, but the sweat glands around the breasts, genitals and armpits produce sweat that contains fat.
Millions of North Americans take zinc lozenges to treat their colds. A study in the Archives of Internal Medicine showed that they neither shorten the cold nor lessen its symptoms. Another study from the University of Virginia showed that zinc nasal sprays do not prevent or treat the common cold.
If you belch or have burning in your stomach or chest, particularly when your stomach is empty, you probably have either an infection, a tumor, or a condition called GERD (reflux or regurgitation). Infection with bacteria such as helicobacter pylori is by far the most common cause.
A single CT scan routinely used to evaluate patients for heart disease emits more than 150 times the amount of radiation that comes from a single chest X-ray. Radiation can damage the DNA genetic material in cells, kill some cells, and cause increased expression of genes involved in the repair or death of cells...
A study from the University of California, San Diego shows that fermentation of sugar takes the least amount of energy for cells to grow and thrive (Nature, December 3, 2015). I think this study shows how cancer will be cured in the not-so-distant future. Cancer cells multiply so much faster than normal cells do...
A popular natural health newsletter tells you that toxic sludge builds up in your colon, and of course they will sell you a product to remove it. This is nonsense. You don't need to cleanse your colon, and frequent use of these products can be harmful. Colon cleansers are laxatives that soften your stool. They...
The most common complaint among older people is constipation. If you have constipation, check with your doctor who often orders thyroid tests and a barium enema to rule out a cancer or other obstruction or diabetic nerve damage. Usually these tests are normal and you need to correct your diet. Eat whole grains and stop eating foods made from white flour.
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...
If you have been diagnosed as having sinusitis, and have sought help from allergists, ear-nose-and-throat-doctors, internists or surgeons, you know that you still have sinusitis, even though you may have had surgery, allergy shots, all kinds of medications and shots or any other treatment.
We do not know how safe sunscreens are because they have never been tested systematically. Oxybenzone in sunscreens has been shown to be absorbed into the bloodstream in humans, and to disrupt hormones in animals. Zinc oxide and titanium dioxide appear to be safe, except that manufacturers often convert them to nanoparticles that can be inhaled.
A bunion is a bony prominence on the side of the foot, at the base of the big toe joint. This enlargement of the joint, spurring, bump or lump can be aggravated by sports or tight shoes. There is progressive movement of the big toe toward the other toes.
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.
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....
If you notice dark brown or whitish circles on your skin, particularly on your chest or back, you probably have a fungus infection called tinea versicolor. Tinea versicolor is especially noticeable as white spots on your skin when you try to get a suntan. You don't have to treat it as it usually causes no harm...
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.
The American Association for Cancer Research reports that being overweight is linked to 25 percent of cancers, and adding lack of exercise and eating pro-inflammatory foods raises the risk to 33 percent of newly diagnosed cancer cases in the U.S.
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.
Two recent studies show that non-ionizing radiation from cell phones may be associated with impaired ability to recall images, but not words, in teenagers; and at high levels, can increase brain and heart tumors in rats. Most studies on cell phone use have not shown increased cancer risk or memory loss.
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.
Colds and pneumonia are caused by infection. You do not pick up infections from cold weather, you get germs from other people who sneeze or cough in your face or transmit germs with their hands to objects that you touch.
Autophagy means "self-eating". When a cell is damaged or dies, the body quickly breaks down the dead cell’s parts (protein-making, power-generating, and transport systems) into small molecules that can be reassembled to be used for making new cell parts and supplying the energy to power these processes.
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.
The risk factors for a heart attack are also risk factors for many cancers. People who are at 20 percent increased risk for suffering a heart attack in 10 years are three times more likely to develop cancer in 10 years, while those who develop a heart attack, heart failure or atrial fibrillation are seven times more likely to develop a cancer.
Post Traumatic Stress Disorder, or PTSD, means that a person has excessive fear, depression and inability to function normally after witnessing or experiencing intense fear or helplessness. While most commonly associated with veterans of combat or captivity, PTSD can also occur after:
Thirteen percent of North American men and seven percent of women suffer from kidney stones which can be incredibly painful to pass from the kidneys to the bladder. Those who get one stone have a 50 percent chance of passing another stone within the next five years. Here are the current recommendations for preventing kidney stones:
