fork4Considering gastric bypass surgery to help lower your risk of heart disease, type 2 diabetes and other complications related to excess weight? Researchers say there may be one more benefit to the procedure: It can help normalize irregular menstrual cycles.

In a new study in the journal Gynecological Endocrinology, researchers studied 13 premenopausal women with longer than normal menstrual cycles (longer than 40 days) or who didn’t menstruate who underwent gastric bypass surgery.

What they found: One year after surgery, 85% (11 of the 13 patients) experienced regular menstrual cycles.

Why the change? Excess weight often leads to excess insulin production and insulin resistance, which impact your body’s hormone production, throwing it out of balance. Gastric bypass helps normalize insulin and reduce insulin resistance, which in turn helps rebalance your hormones.
