We have our hormones to blame for those crazy PMS symptoms. As estrogen levels fluctuate, so do levels of the stress hormone cortisol. The body wants to keep these levels even, so it turns on the fight or flight response, causing us, the innocent bystanders of this whole thing, to crave carbohydrates and fat. Bring on the ice cream and potato chips. But there's another culprit here; serotonin. Serotonin is that brain chemical that increases feelings of contentment. Foods can trigger serotonin, as can exercise and other lifestyle factors. If cortisol, the stress hormone is high, and serotonin is low, we'll crave simple carbohydrates and fats, usually sugary treats like candy and chocolate. This is because these simple carbs will up our serotonin fast. If cortisol is elevated, but serotonin is normal, we'll crave carbs and fat, but not necessarily that sugary treat. You may find you crave croissants or bagels loaded with peanut butter or cream cheese.
Its normal for your hormones to be raging around your period. It boils down to basics. Your stress levels go up and your eating habits do too. Some eat less during this time. Its nothing to worry about. Your a healthy lady ;) Dont stress so much over it. If your worried it could become an weight issue then try going running or doing soothing things.
