The Curious Case of the Nervous TummySource:

Have you ever experienced butterflies in your stomach before a big event or felt the need to run to the bathroom when feeling anxious? These are just a few examples of the infamous nervous tummy. In this article, we will explore the science behind this curious case and provide some tips on how to manage it.

What is the Nervous Tummy?

The nervous tummy is a common physical response to stress, anxiety, or fear. It can manifest in various ways such as stomach pain, cramps, nausea, bloating, diarrhea, or constipation. The reason why the gut reacts to emotional stimuli is due to the gut-brain axis, a complex network of communication between the central nervous system and the enteric nervous system.

The enteric nervous system, also known as the second brain, is a network of neurons and neurotransmitters that governs the digestive system’s functions independently of the brain but also communicates with it. The gut has its own sensory receptors that can detect changes in the environment and send signals to the brain, influencing mood, behavior, and cognition.

Thus, when you are under stress, your brain sends signals to the gut, causing it to either slow down or speed up its activity, leading to the symptoms mentioned above. The nervous tummy can happen to anyone, regardless of age, gender, or health status, but some people are more prone to it than others.

The Role of Cortisol

The Role Of CortisolSource:

Cortisol is a hormone produced by the adrenal gland in response to stress. It is known as the “stress hormone” because it helps the body cope with stress by increasing blood sugar levels, suppressing the immune system, and activating the fight-or-flight response.

However, prolonged exposure to cortisol can have detrimental effects on the body, such as weight gain, high blood pressure, and digestive problems. Cortisol can affect the gut by altering the gut microbiome, increasing gut permeability, and decreasing gut motility, leading to inflammation, infections, and food sensitivities.

Therefore, managing cortisol levels is crucial for maintaining a healthy gut and reducing the risk of the nervous tummy. Some ways to lower cortisol levels include exercise, meditation, deep breathing, adequate sleep, and a balanced diet.

The Gut-Brain Connection

The Gut-Brain ConnectionSource:

The gut and the brain are closely interrelated, and their communication is bidirectional. The gut sends signals to the brain via the vagus nerve, which is responsible for regulating various bodily functions such as heart rate, breathing, and digestion.

The brain also sends signals to the gut via the hypothalamus-pituitary-adrenal (HPA) axis, which is responsible for the stress response. The HPA axis can activate the sympathetic nervous system, which can decrease gut motility and increase gut permeability, leading to inflammation and other gut problems.

Therefore, maintaining a healthy gut-brain connection is essential for overall health and well-being. Some ways to improve the gut-brain connection include eating a diverse and plant-based diet, taking probiotics and prebiotics, reducing stress, and getting enough sleep.

Managing the Nervous Tummy

If you are experiencing the nervous tummy, there are some things you can do to alleviate the symptoms and prevent them from recurring. Here are some tips:

Eat Mindfully

When you are stressed or anxious, you may tend to overeat or undereat, leading to digestive problems. Try to eat slowly, chew your food well, and avoid eating too much or too little. Also, avoid foods that can trigger your symptoms, such as spicy, fatty, or processed foods.

Stay Hydrated

Dehydration can worsen digestive problems, so make sure to drink enough water throughout the day. You can also drink herbal teas or warm water with lemon to soothe your gut.

Exercise Regularly

Exercise can help reduce stress and improve gut motility, leading to better digestion. You don’t have to do intense workouts; simple activities such as walking, yoga, or swimming can make a difference.

Practice Relaxation Techniques

Relaxation techniques such as meditation, deep breathing, or progressive muscle relaxation can help reduce stress and cortisol levels, leading to a calmer gut. You can also try aromatherapy or massage therapy to relax your body and mind.

Get Enough Sleep

Sleep is crucial for the body’s recovery and repair, including the gut. Lack of sleep can increase cortisol levels and disrupt the gut microbiome, leading to digestive problems. Try to sleep at least 7-8 hours per night and establish a regular sleep-wake cycle.



The nervous tummy is a common yet mysterious phenomenon that affects many people. Understanding the science behind it and implementing some lifestyle changes can help manage the symptoms and improve overall gut health. Remember to eat mindfully, stay hydrated, exercise regularly, practice relaxation techniques, and get enough sleep.
