Consequences of Obesity Obesity is a complex health issue to address. Obesity results from a combination of causes and contributing factors, including individual factors such as behavior and genetics.
Radiation risk from medical imaging Updated: April 2, Published: October, There's been a lot in the media about radiation exposure from medical imaging, and many of my patients are asking about it. They want to know if radiation from mammograms, bone density tests, computed tomography CT scans, and so forth will increase their risk of developing cancer.
For most women, there's very little risk from routine x-ray imaging such as mammography or dental x-rays. But many experts are concerned about an explosion in the use of higher radiation—dose tests, such as CT and nuclear imaging.
Over 80 million CT scans are performed in the United States each year, compared with just three million in There are good reasons for this trend. CT scanning and nuclear imaging have revolutionized diagnosis and treatment, almost eliminating the need for once-common exploratory surgeries and many other invasive and potentially risky procedures.
The benefits of these tests, when they're appropriate, far outweigh any radiation-associated cancer risks, and the risk from a single CT scan or nuclear imaging test is quite small. But are we courting future public health problems?
Exposure to ionizing radiation on the rise The radiation you get from x-ray, CT, and nuclear imaging is ionizing radiation — high-energy wavelengths or particles that penetrate tissue to reveal the body's internal organs and structures.
Ionizing radiation can damage DNA, and although your cells repair most of the damage, they sometimes do the job imperfectly, leaving small areas of "misrepair. We're exposed to small doses of ionizing radiation from natural sources all the time — in particular, cosmic radiation, mainly from the sun, and radon, a radioactive gas that comes from the natural breakdown of uranium in soil, rock, water, and building materials.
How much of this so-called background radiation you are exposed to depends on many factors, including altitude and home ventilation. But the average is 3 millisieverts mSv per year.
A millisievert is a measure of radiation exposure; see "Measuring radiation.
Measuring radiation If you mention the measurement of radiation, many people will recall the classic Geiger counter with its crescendo of clicks. But Geiger counters detect only the intensity of radioactive emissions.
Measuring their impact on human tissues and health is more difficult. That's where the sievert Sv and millisievert mSv come in.
These units, the ones most commonly used in comparing imaging procedures, take into account the biological effect of radiation, which varies with the type of radiation and the vulnerability of the affected body tissue.A health risk assessment (also referred to as a health risk appraisal and health & well-being assessment) is one of the most widely used screening tools in the field of health promotion and is often the first step in multi-component health promotion programs.
Waist Circumference. Measuring waist circumference helps screen for possible health risks that come with overweight and obesity.
If most of your fat is around your waist rather than at your hips, you’re at a higher risk for heart disease and type 2 diabetes. This concerns medical experts because marijuana use during pregnancy is linked to lower birth weight 10 and increased risk of both brain and behavioral problems in babies.
If a pregnant woman uses marijuana, the drug may affect certain developing parts of the fetus's brain. Losing even more weight has been shown to lower the risk even more.
Type 2 Diabetes. Most people who have type 2 diabetes are overweight or obese. You can cut your risk of developing type 2 diabetes by losing weight, eating a balanced diet, getting adequate sleep, and exercising more.
About the NMCPHC Workplace HRA: The Navy and Marine Corps Public Health Center (NMCPHC) Workplace Health Risk Assessment (HRA) is a brief, anonymous, optional tool for military members and GS civilians which measures lifestyle behaviors that are most commonly associated with adverse health outcomes.
Users are asked to select their workplace. Health care practitioners routinely collect family health history to help identify people at high risk of obesity-related diseases such as diabetes, cardiovascular diseases, and some forms of cancer. Family health history reflects the effects of shared genetics and environment among close relatives.
