A new study has indicated that weight loss might help middle-aged women who are overweight or obese reduce bothersome hot flashes accompanying menopause. There has been information known that obesity negatively affects hot flashes. There seems to be data that losing weight can reduce hot flashes. Study participants were part of an intensive lifestyle-intervention program designed to help them lose between 7 percent and 9 percent of their weight. At the study’s start, about half of both the study and control groups reported having hot flashes; about half of these were at least moderately bothered, and 8.4 percent were extremely bothered. Participants were not told that weight might influence hot flashes. After six months of losing weight, 49 percent in the study group, compared with 41 percent in the control group, reported improvement in frequency and duration.
