Yes, research shows there may be some benefits to drinking coffee. But I believe that the risks for women with active hormone issues—like PMS, PCOS, fibroids, endometriosis, and difficulty becoming pregnant—not only outweigh any benefits but could also exacerbate these conditions. The female body is brilliantly designed to conserve as much energy from whatever we’re consuming so we can grow tiny humans in our uterus—amazing, right? Whether you are actively doing this or not, your body is built to retain fluids for much longer and to metabolize the chemicals contained much more slowly. That said, if you’re skipping breakfast and caffeinating on an empty stomach or even using coffee as a meal replacement, you might feel those negative effects of coffee way more quickly.
