The Science Behind Anxiety’s Impact on Your Digestive System
Fight-or-Flight Response: Anxiety triggers the body’s "fight-or-flight" response, releasing stress hormones like cortisol and adrenaline.
Gut-Brain Connection: The brain and gut are closely connected through the vagus nerve, which allows signals to travel between them.
Increased Stomach Acid: Anxiety often increases stomach acid production, which can lead to heartburn, acid reflux, or stomach ulcers over time.
Reduced Blood Flow to the Gut: During anxious moments, blood is redirected to muscles and organs that are crucial for survival.
Digestive Discomfort: Anxiety can lead to bloating, constipation, diarrhea, or nausea. The body may be in a constant state of tension, disrupting normal digestive processes.
Altered Gut Microbiome: Stress and anxiety can alter the balance of gut bacteria, potentially contributing to digestive issues like irritable bowel syndrome (IBS).
Increased Gut Sensitivity: Anxiety can increase gut motility, making it more prone to cramps and irregular bowel movements.
Slower Digestion: Chronic anxiety can lead to slower digestive processes, meaning food stays in the stomach longer and causes discomfort.
