Stress and anxiety can trigger various physical symptoms, including diarrhea. Stress hormones enter the digestive tract and disrupt beneficial gut bacteria balance.
Stress is a natural response of your body when faced with threats and challenges, such as threats of physical harm. Once these challenges have passed, your resting state returns; however, if prolonged anxiety continues, other responses from your body may become apparent.
Stress Causes a Chemical Imbalance
Your body's natural response to stress is to activate its sympathetic nervous system, which regulates bodily functions such as your heartbeat and breathing. Once activated, this system triggers a fight-or-flight response releasing cortisol as part of its fight-or-flight response, making you alert and ready to act in response to whatever threat presents itself.
As soon as a threat has passed, your body should automatically reduce the stress response and return to a state of equilibrium. However, prolonged overstimulation of the nervous system can alter how your gut and brain communicate leading to issues like diarrhea, bloating and constipation.
Your brain and gut are connected, constantly communicating with one another, which explains why you may experience "butterflies" when making difficult decisions or becoming anxious about an upcoming event. Studies have discovered that more neurons reside in your gut than any spinal cord - meaning your gut is highly responsive to signals sent from your brain, easily overstimulated by short-term stressors or chronic worries.
It Slows Down Your Digestion
Stress causes the body to go into "fight or flight" mode, diverting blood and energy away from digestion in favor of muscles and organs necessary for survival. As a result, digestive processes slow or cease functioning altogether leading to buildups of waste in the digestive tract resulting in gas, bloat, or stomach discomfort.
Food requires time in your digestive tract for absorption and waste elimination; when stressed, this process can become disrupted and it becomes hard to digest foods. If you're experiencing issues like diarrhea, kabz ka ilaj, bloating or constipation that don't seem to go away using home treatments alone, contact Northeast Digestive immediately for professional assistance.
Your gut is often considered your second brain and continuously sends signals to your central nervous system, impacting both your mood and anxiety levels, as well as digestive symptoms.
It Causes a Bacterial Overgrowth
Researchers have established that the gastrointestinal tract contains the largest concentration of nerves outside the brain, and a strong connection exists between this area and our brains. Therefore, many people suffering from anxiety report experiencing stomach symptoms like stomach pain, bloating, diarrhea or constipation as a symptom.
Functional Gastrointestinal Disorders affect approximately 35-70% of the population and result from changes to how your body processes food; often without any known medical cause such as an illness or infection.
Stress activates the sympathetic nervous system which controls your fight or flight response. This triggers more blood to go directly to muscles while slowing or stopping digestion in your stomach - over time this could lead to IBS symptoms and other digestive disorders; keeping stress at a manageable level is the best way to protect against their development.
It Causes a Nervous Response
Your brain and gut are intrinsically linked. Some experts even refer to your stomach as having its own "mini brain". In either case, both areas remain in constant communication with each other.
Under stress, your nervous system triggers what is known as the "fight or flight" response. This response allows your body to quickly escape danger by shutting down parts that are unnecessary for doing so - including your enteric nervous system - which directly controls your GI tract. This part of the autonomic nervous system shuts down when activated during stressful moments. However, always consult with medical professional before using any pakistan herbal products or medictaions.
As such, when faced with intense stress levels you may experience symptoms like bloating, abdominal pain, diarrhoea or constipation which are typically the result of stress and anxiety. Stress-induced functional gastrointestinal disorders characterized by abdominal pain and other related GI symptoms arising without clear physical causes may also arise due to anxiety-driven anxiety attacks.
