Unreasonable deadlines. Being stuck in traffic. Having too much to do and not enough time to do it in. Most of us are familiar with these kinds of daily stresses that get our heart racing, our breath quickening, and our stomach churning. Of course, just having a digestive condition can be a source of anxiety in itself. Studies show that a major stressful event long-since passed could still be affecting your gut even now. Being stressed-out also causes many of us to overeat and drink too much alcohol, both of which affect our gut.
What is the real effect of stress on our gut? Many studies show that stressful life events are associated with the onset of symptoms, or worsening of symptoms, in several digestive conditions, including inflammatory bowel disease (IBD), irritable bowel syndrome (IBS), gastroesophageal reflux disease (GERD), and peptic ulcer disease.1
