There are several different types of kidney stones, but each of them can cause a lot of pain.
Kidney stones are small chunks of solid material that can form in your kidneys, a pair of organs that filter your blood.
The “stones,” which are usually yellow and brown, vary in size and shape.
For instance, some may be jagged and as small as a grain of sand, while others may be lumpy and the size of golf balls.
A stone may stay in the kidney or travel down the urinary tract — the body’s waste and excess-water drainage system — and get stuck, causing severe pain in the belly or side of the back.
Other symptoms may include nausea, chills, and blood in the urine.
Prevalence and Demographics of Kidney Stones
Kidney stones are one of the most common disorders of the urinary tract, resulting in more than a million visits to health care providers and 300,000 emergency room visits each year in the United States, according to the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK).
About one in 11 people in the United States, or 8.8 percent of the population, have had a kidney stone,
Holding a cell phone to your ear for a long period of time increases activity in parts of the brain close to the antenna, researchers have found.
Glucose metabolism — that’s a measurement of how the brain uses energy — in these areas increased significantly when the phone was turned on and muted, compared with when it was off, Dr. Nora Volkow, director of the National Institute on Drug Abuse, and colleagues reported in the Journal of the American Medical Association.
“Although we cannot determine the clinical significance, our results give evidence that the human brain is sensitive to the effects of radiofrequency-electromagnetic fields from acute cell phone exposures,” co-author Dr. Gene-Jack Wang of Brookhaven National Laboratory in Long Island, where the study was conducted, told MedPage Today.
What We Know About Cell Phones and Cancer
Although the study can’t draw conclusions about long-term implications, other researchers are calling the findings significant.
“Clearly there is an acute effect, and the important question is whether this acute effect is associated with events that may be damaging to the brain or predispose to the development of future problems such as cancer as suggested
Did you know that your body weight is approximately 60 percent water? Your body uses water in all its cells, organs, and tissues to help regulate its temperature and maintain other bodily functions. Because your body loses water through breathing, sweating, and digestion, it’s important to rehydrate by drinking fluids and eating foods that contain water. The amount of water you need depends on a variety of factors, including the climate you live in, how physically active you are, and whether you’re experiencing an illness or have any other health problems.
Water Protects Your Tissues, Spinal Cord, and Joints
Water does more than just quench your thirst and regulate your body’s temperature; it also keeps the tissues in your body moist. You know how it feels when your eyes, nose, or mouth gets dry? Keeping your body hydrated helps it retain optimum levels of moisture in these sensitive areas, as well as in the blood, bones, and the brain. In addition, water helps protect the spinal cord, and it acts as a lubricant and cushion for your joints.
Water Helps Your Body Remove Waste
Adequate water intake enables your body to excrete waste through perspiration, urination,
Barely a week goes by, it seems, without some company announcing a new pill designed to help you live a longer, healthier life.
Medication can, indeed, do a lot toward curing, preventing or easing many ills. But taking a fistful of pills each day creates its own set of medical risks, prompting concern among a growing number of physicians and pharmacists that people are simply taking too many medications for their own good.
“As you keep increasing the amount of prescriptions, that increases the chance of having a drug interaction or major side effect,” said Sophia De Monte, a pharmacist in Nesconset, N.Y., and a spokeswoman for the American Pharmacists Association. “It’s exponential. The more you add on, the more chance you’ll have something bad happen.”
It’s a concept called polypharmacy, the use of more medications than someone actually needs. And that means not just prescription drugs but also over-the-counter medications and dietary supplements.
The average American is prescribed medication about 13 times a year, according to a report last year by the Kaiser Family Foundation. But the likelihood of polypharmacy increases as people age. Studies have found that seniors make up 13 percent of the population but account for 30 percent of all
Monday, Jan. 31, 2011 – Regular aerobic exercise such as walking may protect the memory center in the brain, while stretching exercise may cause the center — called the hippocampus — to shrink, researchers reported.
In a randomized study involving men and women in their mid-60s, walking three times a week for a year led to increases in the volume of the hippocampus, which plays an important role in memory, according to Dr. Arthur Kramer, of the University of Illinois Urbana-Champaign in Urbana, Ill., and colleagues.
On the other hand, control participants who took stretching classes saw drops in the volume of the hippocampus, Kramer and colleagues reported online in the Proceedings of the National Academy of Sciences.
The findings suggest that it’s possible to overcome the age-related decline in hippocampal volume with only moderate exercise, Kramer told MedPage Today, leading to better fitness and perhaps to better spatial memory. “I don’t see a down side to it,” he said.
The volume of the hippocampus is known to fall with age by between 1 percent and 2 percent a year, the researchers noted, leading to impaired memory and increased risk for dementia.
But animal research suggests that exercise
