A small but growing body of research shows that GLP-1 drugs often used to treat obesity may also work for the hormonal disorder known as PMOS. They are believed to help women with PMOS not only by promoting weight loss but also by improving insulin resistance, hormone balance and ovulation. These things are key to the disease, which used to be called PCOS but was renamed earlier this year to shift the focus away from ovaries and cysts. Colorado teen Charlotte Touzalin joined a study testing the treatment. On the GLP-1, she stopped constantly gaining weight and her periods normalized.
