Menstrual Phase Impacts Exercise Effects in Type 1 Diabetes
Women with type 1 diabetes may need additional glucose after exercise during the luteal phase of the menstrual cycle, compared with other times, according to a study in nine women.
@rituparna The menstrual cycle could be an additional barrier to exercise for women with T1D because it increases glucose fluctuations that have not been well documented in the literature to date, said Yardley, of the University of Alberta, Augustana. The follicular phase of the menstrual cycle lasts from menses to the midcycle, about 14 days later. This is followed by the luteal phase, which lasts until approximately day 28, Yardley explained. Data on insulin sensitivity have shown that the late luteal phase is associated with "a little less insulin sensitivity" in women with T1D, she noted.
