The Hidden Link Between Anxiety and Your Gut Health

We all experience stress and anxiety in our own way and may have a variety of symptoms as a result. However, you have undoubtedly heard many people say that their stomach is in knots or they feel nauseous when they are having a tough time with anxiety. There is a growing body of research suggesting that there is a link between anxiety and your gut health. Unsurprisingly, the gut is home to trillions of microorganisms, collectively known as the gut microbiota, which play a crucial role in many aspects of our health, including digestion, immunity, and mental health.

What is anxiety?

Anxiety is a common mental health condition that affects millions of people worldwide. It is characterized by feelings of worry, nervousness, and fear that can interfere with daily activities and lead to physical symptoms such as headaches, muscle tension, and digestive issues. While anxiety is often treated with medication and therapy, recent research suggests that there may be a hidden link between anxiety and your gut health.

The gut-anxiety connection

The gut is often referred to as the “second brain” because of the close relationship between the digestive system and the nervous system. In fact, the gut has its own network of neurons, called the enteric nervous system, which communicates with the brain through the vagus nerve. This connection allows the gut to send signals to the brain, influencing mood, behavior, and even cognitive function.

Several studies have shown that people with anxiety and other mental health conditions tend to have a different composition of gut microbiota than those without anxiety. Specifically, they may have lower levels of beneficial bacteria and higher levels of harmful bacteria. This can lead to a disrupted gut-brain axis, a bidirectional communication pathway between the gut and brain essential for maintaining mental and emotional well-being.

Those with anxiety are more likely to experience digestive issues such as bloating, constipation, and diarrhea. Additionally, research has found that people with irritable bowel syndrome (IBS), a chronic digestive disorder, are more likely to experience anxiety and depression.

Are your brain and gut communicating?

One theory behind the link between anxiety and your gut health is that imbalances in the gut microbiome, the collection of microorganisms that live in the digestive tract, can lead to inflammation and changes in neurotransmitter levels that contribute to anxiety symptoms. For example, low levels of the neurotransmitter serotonin, which is produced in the gut, have been linked to both anxiety and digestive issues.

Another possible explanation is that the gut-brain axis, the communication system between the gut and the brain, may be disrupted in people with anxiety. Stress, a common trigger for anxiety, can cause changes in gut motility and increase gut permeability, which allows toxins and bacteria to enter the bloodstream and potentially affect brain function.

How do we repair the connection?

So, what can be done to improve gut health and potentially alleviate anxiety symptoms? Let’s take a look at some steps that are simple enough for anyone to give a try.

Eat a healthy diet

One approach is to focus on a healthy diet that supports a diverse microbiome. This includes eating plenty of fruits and vegetables, whole grains, and fermented foods that contain probiotics, beneficial bacteria that can help balance the gut microbiome. Additionally, avoiding processed foods, sugar, and unhealthy fats can reduce inflammation in the gut and promote overall well-being.

Manage stress

Chronic stress can negatively impact both mental and physical health, including an imbalance in gut bacteria and increased anxiety symptoms. However, there are various ways to reduce stress and promote relaxation, such as practicing yoga, meditation, or deep breathing exercises. For instance, moving can be a significant source of stress, especially if you’re moving in Miami-Dade County. The good news is that hiring moving pros can make it stress-free. This can significantly alleviate the moving day anxiety that many people experience. To further ease the stress of the moving day, consider preparing simple and easy-to-eat moving-day meals to keep your energy levels up and your stomach settled.

Exercise regularly

Recent research has provided strong evidence that exercise can benefit not only our physical health but also our gut health and mental well-being. Regular exercise can enhance the diversity of our gut microbiome and has been shown to reduce symptoms of anxiety and depression by triggering the release of mood-boosting endorphins and reducing stress hormones like cortisol. Even moderate exercise, such as walking, can have a positive impact on gut microbiome diversity and anxiety reduction, making it an accessible and effective way to improve both physical and mental health. Therefore, incorporating regular exercise into our daily routine can not only help us stay physically fit but also improve our overall quality of life.

Get enough sleep

Sleep plays a crucial role in maintaining optimal physical and mental health, and it is particularly important for maintaining the health of both the gut and the mind. Not getting enough sleep can hurt our gut health, disrupting gut function and leading to inflammation and poor digestion. This, in turn, can cause a range of unpleasant symptoms, such as abdominal pain, bloating, and constipation.

Moreover, sleep deprivation can also have a detrimental effect on our mental well-being. A lack of sleep is associated with an increased risk of anxiety and other mental health issues, such as depression, mood swings, and irritability. This is because sleep plays a critical role in regulating our emotions and cognitive function, helping to restore balance and maintain a healthy mental state.

Take probiotics

For some people, a probiotic supplement may be beneficial in restoring gut balance. However, it’s important to consult a healthcare provider before starting new supplements, as some may interact with medications or have other potential risks.

Probiotics are beneficial bacteria that can help support gut health and alleviate anxiety symptoms. Probiotic supplements and fermented foods such as yogurt, kimchi, and sauerkraut can provide a natural source of beneficial bacteria for the gut.

Seek professional help

If anxiety symptoms persist, seeking professional help from a mental health professional or medical doctor is crucial. They can provide personalized recommendations and treatment options to help alleviate symptoms and improve gut health.

The takeaway

While the link between anxiety and your gut health is still being studied, there is growing evidence to suggest that the gut-brain axis plays a key role in mental health. By taking steps to support gut health, it may be possible to alleviate some of the anxiety symptoms and improve overall well-being.

What’s inside your gut may be the reason for your poor health . . .

Many health conditions and psychological symptoms originate in your gut.  Your enteric nervous system, or “second brain,” is home to an abundance of neurons and produces an array of neurotransmitters. It is also where trillions of microorganisms (collectively known as your gut microbiome) reside.  You are, in fact, only 10% human as each of these microorganisms has its own DNA and they outnumber the total number of cells in your body by at least 10.  Your microbiome weighs an average of 3-6 pounds.  These tiny microorganisms include bacteria, yeast, fungi, mold and parasites and they play an enormous role  in determining your health.

While capable of functioning independently, your enteric nervous system and central nervous system “speak”(i.e., via the vagus nerve)  to one another all the time.  In fact, about 90% of your body’s serotonin (a feel good neurotransmitter) and 50% of your dopamine is produced in your enteric nervous system by your gut microbiome.

People who experience various digestive disorders and psychological syndromes including food allergies and intolerances, frequent gas and bloating, diarrhea and constipation, symptoms of anxiety or depression, schizophrenia and ADHD or who suffer from auto immune conditions frequently  have an imbalance of gut microorganisms; a condition known as gut dysbiosis.1,2,3

Many lifestyle factors affect how your gut functions and the health of your gut microbiome.  The standard American diet that is full of refined sugars and processed foods, stress, “dirty” electricity (i.e., nEMFs), poor quality and insufficient sleep, pesticides, herbicides, antibiotic medications and birth control pills negatively impact the health of the friendly probiotic bacteria in your gut.4

Animal studies have found that the administration of antibiotics leads to a significant increase in fearful behavior.  Conversely, the addition of probiotic supplements has been found to decrease such anxious behavior.5 Human studies have also found that the administration of beneficial probiotic supplements significantly reduces symptoms of anxiety and depression.2

An important principle to adopt to ensure optimal health and prevent many physical and mental health problems is to make sure that you include probiotic rich fermented foods in your diet.  Traditionally fermented foods, like sauerkraut and kim chi, are rich sources of friendly bacteria and yeast and help to support your immune system because they contain many B vitamins, omega-3 fatty acids, digestive enzymes, lactase and lactic acid, and other immune chemicals that fight off harmful bacteria and cancer cells.   Aim to eat multiple servings of probiotic rich fermented foods every week to support your overall health and well-being.
