Recently, my friend and colleague, Dr. Melissa Fougere wrote an article explaining the intricate relationship between your brain and your digestive tract. Most people would not think these two systems are related, but they share many of the same cells that communicate extensively with one another. It also helps explain why emotions such as nervousness, anxiety, and stress are expressed physially with digestive symptoms such as nausea, diarrhea, or constipation.
All the more reason for you to ensure that your digestive system is working optimally, and not to ignore symptoms such as constipation or cramping that may seem normal, because they are not. Contact a Naturopathic Doctor who can work with you to see if your tummy could use some tweaking!
