If you lose feeling in a particular part of your body, lose control of your muscles or have abnormal nerve sensations such unexplained pain, burning in your feet, tingling or itching, you usually have a neuropathy: nerve damage. Nerves can be damaged by something pinching or stretching them, such as excessive pressure from moving a limb repeatedly (as in carpal tunnel syndrome in your hand), scar tissue, or a disc problem in your back.
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 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.
A neuroma is a swollen or damaged nerve. This often occurs between the bones that your toes attach to on the foot, most commonly between the third and fourth toes. Neuroma can be caused by tight shoes, repetitive stress or trauma.
A 6.5-year-long study followed 826 people who had been diagnosed with colon cancer that had already spread to their lymph nodes and been treated with chemotherapy and radiation. The researchers found that those who ate at least two one-ounce servings of tree nuts per week gained a 42 percent reduced rate of cancer recurrence and and a 57 percent reduced risk for death during the study period.
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.
A study this month showed that prunes are an effective treatment for constipation, with 120 healthy adults, who did not eat a lot of fruits and vegetables and had bowel movements only 3 to 6 times a week, assigned to groups given either 0, 10 or 15 prunes per day for 4 weeks.
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.
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.
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.
Researchers at Stanford reviewed the medical records of nearly three million people and found that those who took a type of ulcer medication called Proton Pump Inhibitors (PPIs) were almost 20 percent more likely to suffer heart attacks than those not taking these drugs (PLoS ONE. June 10, 2015). PPIs reduce excess stomach acidity...
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...
Deaths from cancer of the liver are increasing every year. Each year, more than 35,000 North Americans develop liver cancer and 25,000 die from it. Less than 20 percent of liver cancer patients are alive five years after being diagnosed. If the cancer is diagnosed after it has spread to surrounding tissues, the five-year survival rate drops to 11 percent.
A seven-year study of 992 patients with colon cancer that had already spread to their bellies had a 42 percent reduction in death rate and a 31 percent reduction in recurrence of their cancer when they avoided overweight, exercised regularly (one hour of walking per day), ate a diet rich in whole grains, vegetables and fruits, and low in red meat and processed meat, and restricted alcohol.
Don't put your faith in the many advertisements for ultraviolet light machines making claims that they destroy SARS-CoV-2, the virus that causes COVID-19. They have not been shown to be effective, and UV rays strong enough to kill a virus may also damage your skin and eyes.
Almost all skin cancers are caused by excessive exposure to sunlight. Basal and squamous cell skin cancers are caused by cumulative exposure to sunlight over a lifetime, so every time you expose any part of your skin to direct sunlight, you are adding to the damage that you have received from previous exposures.
Stem cell clinics have sprung up in most states, but are most abundant in Arizona, California, Colorado, Florida, New York and Texas. Last year the FDA sent warning letters to clinics in California, Florida and New York for illegally using stem cells from people's fat tissue to treat conditions such as Parkinson's disease.
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.
As reported by the White House medical team, the drugs given to President Trump to treat COVID-19 included Regeneron's antibody cocktail (monoclonal antibodies), Gilead Sciences' remdesivir (brand name Veklury), and dexamethasone.
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.
Sunscreens offer only partial protection from the sun. It is dangerous to expose large areas of your sun screen-coated skin to sunlight. If you want to really protect your skin from sun damage, get under a roof when the sun is out in full force. Clothes are next best, and sunscreens are a poor third.
For many years we have been told to watch existing moles for changes that may signal a melanoma, but a new review of 38 studies covering 20,126 melanomas shows that fewer than 30 percent of melanomas are found on moles. More than 70 percent of melanomas show up on previously normal skin.
One in 20 North Americans can expect to develop colon cancer, with more than 100,000 new cases each year. A recent review of 80 studies found that most cases of colon cancer are linked to poor lifestyle choices.
A study in the UK that followed 5.24 million people for 7.5 years identified more than 166,000 who developed at least one of 22 cancers. Each 5-point elevation of BMI above normal (equal to about 30 pounds for a person 5'6" tall) was associated with significantly higher risk for cancers of the uterus, gallbladder,...
Tinnitus means that you hear a sound that no one else hears. It can be a buzzing, roaring or ringing and it can even sound like a heart beat. If the sound is pulsatile like a beating heart, the doctor may look for obstructions or widening in the arteries in the brain such as those caused by arteriosclerotic plaques or a ballooning of an artery called an aneurysm
If you get recurrent painful blisters with itching or tingling in your skin, around your mouth or in your genital area, check with your doctor who will usually do a culture of the blisters. If the culture shows that you have an infection with one of the two herpes simplex viruses, your doctor can give you a prescription for pills containing one of three common drugs used to shorten the course of each outbreak of blisters:
The recent medical literature shows that certain lifestyle factors are associated with developing prostate, breast, colon, pancreatic and many other cancers and that changing these same lifestyle factors should be part of every treatment for people who are diagnosed with any type of cancer. Up to 40 percent of human cancers are at least partially caused by modifiable lifestyle factors.
