Ask the doctor: My waist has expanded but I haven't gained weight. Is this because I've stopped wearing a belt?

Q. The article in your December 2014 issue about women's waistlines expanding the past few years intrigued me, because I have experienced an increase, and I have not gained weight. My theory is that the styles of the past few years—pants riding low on the hips, no belts at the waist, and loose shirts—may have caused my waist to increase from 24 to 25½ inches. I am 59 years old, so it also could be aging in general, but I still think the belted styles kept women smaller. Am I right?

A. There is no evidence that the physical effect of wearing a belt influences waist circumference. At best, wearing a belt is one way to keep tabs on your waistline. While having to loosen their belt a notch may drive some women to re-examine their diet and exercise routines, it doesn't sound as if you need to do that. I think your alternative explanation that aging is responsible is more likely to be true.

Gain more weight, get more GERD

Maintaining a healthy weight is the best way to rein in gastroesophageal reflux disease (GERD), or chronic heartburn, according to a study in The American Journal of Gastroenterology. Researchers found that GERD symptoms increased for every incremental rise in body mass index (BMI), which measures the ratio of weight to height.

In GERD, the acidic contents of the stomach back up into the lower esophagus, causing burning pain. The most effective treatment for GERD is taking an acid-reducing proton-pump inhibitor medication, such as omeprazole (Prilosec). People who are overweight are much more likely to develop GERD.

Adding folate to blood pressure medication reduces stroke

People with high blood pressure could benefit from a B vitamin known as folate if they are not getting enough from their diets, according to a study in The Journal of the American Medical Association (JAMA).

The study included more than 20,000 adults in China with high blood pressure who had never had a stroke or heart attack. Participants who took folate supplements along with a blood pressure medication had fewer strokes over the four-and-one-half-year trial than those who only took the medication.

New concerns about diet sodas

They're linked to calorie absorption, high blood pressure, and heart trouble.

For weight-conscious people who love the bite of carbonation and the taste of various soft drinks, the advent of sugar-free sodas 60 years ago seemed a blessing: if there were no calories, you didn't have to worry about weight gain—and the diseases that go along with obesity, like diabetes and heart disease. "But there are growing doubts about whether diet sodas really help people lose weight and avoid diabetes," says Dr. Anthony Komaroff, editor in chief of the Health Letter.
