What is NuvaRing?The birth control ring (NuvaRing) is a relatively new form of hormone-based birth control. It is a flexible, transparent ring that is approximately two inches in diameter that is inserted into the vagina. The position of the NuvaRing is not important for its function. NuvaRing is left in the vagina for three weeks and then removed. After one week, during which time withdrawal bleeding usually occurs, a new NuvaRing is inserted for another three-week cycle. NuvaRing was approved by the United States Food and Drug Administration (FDA) on October 3, 2001.How Does NuvaRing Work?NuvaRing is a combination hormone contraceptive containing - an estrogen and a progestin. NuvaRing is a third generation birth control that uses a different form of progestin than older contraceptives called desogestrel. Those hormones are released into the bloodstream through contact with the vagina. The vaginal walls absorb the hormones and place them into the bloodstream. These hormones are designed to prevent the ovaries from producing mature eggs. In addition, the lining of the uterus becomes thinner which inhibits implantation of a fertilized egg.Is NuvaRing Effective?In three clinical...more

Back in 1991 when I first earned my license to practice chiropractic, I was of the mindset that my typical patient would have complaints of low back pain, neck pain or headaches. By the mid 1990s I was a chiropractor in San Diego with an office full of people suffering from Repetitive Stress Injuries like Carpal Tunnel Syndrome. Instead of my original expectations of having an office full of patients with typical cases of low back pain, I was studying ergonomics and spending the bulk of my time unraveling the negative effects of Postural Stress that was accumulating in these patients secondary to computer work.The study of workstation ergonomics tells us that the objects that we use most often should be located closest to your body and accessed easily, without awkward body positions or movements. Repeated reaching or prolonged fixed postures that involve leaning forward from your chair are stressful and fatiguing. Some people are aware of computer ergonomics and have purchased various ergonomic devices. These devices, such as keyboard trays, gel mouse pads, and ergonomic keyboards rarely provide solutions to the big picture of computer ergonomics. These items must work with each...more
