If you have attempted a low carb lifestyle, as more than a projected 45 million people in the United States have, it is possible that you may experience increased PMS symptoms, or skipped periods. Note: some low-carb diets are also gluten-free such as phase 1 of the South Beach Diet. If you notice a change in digestion, such as less constipation, diarrhea, bloating, please ask to be tested for gluten intolerance. Contact the Cycle Diet dietitian for help in asking for the right tests from your primary doctor.
If you are taking an oral contraceptive it may also be possible that you have experienced mid-cycle breakthrough or spotting. Many women are unaware of the connection between nutrition and their hormones and as a result visit their OB/GYN in a state of panic. Unfortunately many physicians are also unaware of the low-carb diet-hormone connection. As a precautionary measure they proceed to do expensive diagnostic tests, when the first question they should be asking is "How is your diet?" or, "Are you on a LOW CARB DIET?"
