More than half of people say they've suffered lower back pain in the past year, according to the latest NPR-Truven Health Analytics Health Poll.

That's not a surprise; low back pain is very common, and one of the biggest reasons that people seek medical care. But people told us that they're making very different choices in how they treat that pain, with some stark differences among age groups and income levels.

Getting the flu while pregnant doesn't appear to increase the child's risk of being diagnosed with autism later on, a study finds, and neither does getting a flu shot while pregnant.

Erik Vance didn't go to a doctor until he was 18; he grew up in California in a family that practiced Christian Science. "For the first half of my life, I never questioned the power of God to heal me," Vance writes in his new book, Suggestible You: Placebos, False Memories, Hypnosis, and the Power of Your Astonishing Brain.

Not so very long ago, colonoscopy was the gold standard for colon cancer screening. But times are a-changing. Last month when I went in for a checkup, my primary care doctor handed me a FIT test, a colon cancer test you can do at home without the unpleasantness and risk that turn people off to colonoscopy.

The FIT test, or fecal immunochemical blood test, is a newer and more accurate way to test for blood in stool, which can be a symptom of colon cancer.

Women are less likely to die of breast cancer than they were a decade ago, but not all women are benefiting from that trend.

White women saw more of a drop in death rates than black women — 1.9 percent a year from 2010 to 2014, compared to a 1.5 percent decrease for black women, according to a report published Thursday by the Centers for Disease Control and Prevention.

Women had a lot to say about what works — and what doesn't — for treating morning sickness, after we ran a post summarizing the evidence for home remedies and over-the-counter meds.

NPR's Facebook feed lit up with comments from women saying that ginger, acupressure and other home remedies, which were recommended for mild symptoms in a medical journal article published Tuesday, did nothing to tame their nausea and vomiting.

Many people struggling with opioid addiction can't find a doctor to provide medication-assisted treatment, even though it's highly effective. One reason could be that doctors who are qualified to prescribe the medication typically treat just a handful of patients.

Saline nose spray is becoming increasingly popular as a treatment for allergies and sinus problems. And a study suggests the cheap, simple solution helps with severe nosebleeds, too.

Two studies published Tuesday in JAMA, the journal of the American Medical Association, used saline nose spray as a control when testing medications to treat severe nosebleeds caused by a rare genetic condition.

A body mass index under 25 is deemed normal and healthy, and a higher BMI that's "overweight" or "obese" is not. But that might be changing, at least when it comes to risk of death.

The body mass index, or BMI, associated with the lowest risk of death has increased since the 1970s, a study finds, from 23.7, in the "normal" weight category, to 27, which is deemed "overweight."

Immunotherapy tablets are starting to edge out shots as a treatment for allergies. And it looks like the pills can help reduce the frequency of asthma attacks, too.

Scientists reported Tuesday that immunotherapy tablets for dust mite allergy reduced the risk of an attack in people with moderate to severe asthma. The results were published in JAMA, the journal of the American Medical Association.
