Stress can be a factor in having amenorrhea (the absence of a menstrual cycle), but it’s rarely the only one. And as sports nutrition and performance expert Rebecca McConville explains, it goes both ways, in that having RED-S / REDs (Relative Energy Deficiency in Sport) increases the stress in our body.

She describes how food/fuel actually becomes our mood, and how stress affects us physically.

[Tina]  My life is really stressful right now. I have a lot going on; is that why I have RED-S right now? 

[Becca]  It could be. It could be a barrier to connecting with your body, as well, to understand what you need. So RED-S can increase the stress in our body, and one thing that really gets overlooked is that food, fuel, becomes our mood. It’s broken down into neurotransmitters that cross into our brain and then they actually get up there, and then whatever feelings we are expressing will then become a mood. So when we are not eating enough fuel, or enough energy, we actually become kind of a flatter effect, which can feel stressful at times. The other piece of this is, you know, when we’re doing a high level of training, you have to build in time to be able to prepare meals, get your snacks. I think sometimes we make it overly complicated, but when life is stressful, the natural instinct is sometimes to put self-care on the back burner, which then can make the situation even more stressful.

[Tina]  Is a menstrual cycle disruption, can that ever just be from stress and nothing else, or is there usually caloric deficit or other factors involved? 

[Becca]  The literature would say that it can be purely from stress; however, I’ve never seen where somebody is sleeping perfectly, eating enough, training within their parameters, and still super stressed. There’s usually some piece of it that ends up trickling, so I think it’s really hard to isolate that particular variable. And one of the words I really love to use is, we lose our resiliency, right?  When we’re stressed, our body can’t handle even some of the smallest things that normally it would be able to. You know, even viruses and colds, your ability to tolerate maybe stressful environments with your co-workers or your kids, or things like that, which then gets magnified, as well. 

[Tina]  Okay, thank you.
