Can IBS be Caused by Stress? A Functional Nutritionist's Perspective


Can IBS be Caused by Stress?

Many women wonder, "Can IBS be caused by stress?" While stress itself doesn't cause IBS, it can exacerbate the symptoms and trigger flare-ups in individuals already suffering from the condition. Managing stress is often a key component of treatment plans for IBS. But there’s also more at play as well. Let’s dive in so you can get relief from your IBS symptoms. 


What Your Doctor Left Out About IBS

Irritable Bowel Syndrome (IBS) can be a real pain, interfering with your daily life, and a lot of women have to deal with it. But did you know that IBS is more than just a bunch of unexplained symptoms lumped together?


In reality, it's multiple things happening beneath the surface that lead to these IBS symptoms (like emergency bathroom runs, not having a bowel movement in 5 days, or on and off of both these symptoms…)


These aren't just surface-level issues; they are deep down in the cells of our bodies. It's these changes, disturbances, or funky things happening at the cellular level that cause the symptoms we usually chalk up to “IBS”. So, while it's easy for doctor to just say "IBS" and leave it at that, it's important to understand there's a whole lot more going on beneath the surface.


The Connection Between Stress and IBS: Can IBS be Caused by Stress?

In today's fast-paced world, we all seem to be constantly under stress, right? It's not just about having a rough day at work anymore. This kind of stress is always present, like a little voice at the back of your head, reminding you of everything you didn’t get done for the day. 

It could be because we're juggling so many things at once, worrying about finances, sorting out relationship issues, or even dealing with health problems. This constant pressure can really mess with your gut health, ladies.


Let's talk about the ways chronic stress can impact your gut:


  • Altering Gut Motility: Stress has a sneaky way of influencing how fast food travels through your digestive system. This can lead to issues like diarrhea or constipation, which you might recognize as common symptoms of IBS. This happens because stress can trigger your body's "fight or flight" response, which changes the pace of your digestion.

  • Impacting Digestive Secretions: Stress can also put a damper on the production of stomach acid and digestive enzymes, both of which are vital for proper digestion. When you're stressed, your body might produce less of these essential digestive components, leading to problems like heartburn and malabsorption. Over time, this could contribute to the development of IBS.

  • Triggering Food Sensitivities: When you're under chronic stress, it might even make your food sensitivities or intolerances worse, which are often linked to IBS. This happens because stress can cause inflammation in your gut, leading to an increased sensitivity to certain foods.

  • Affecting the Gut-Brain Axis: Stress can interfere with the conversation between your brain and your gut, often referred to as the gut-brain axis. This interference can lead to increased sensitivity to pain, changes in gut motility, and altered gut secretions, all of which can contribute to IBS symptoms.

  • Inhibiting Nutrient Absorption: Stress can also mess with your body's ability to absorb nutrients effectively due to its impact on the gut's permeability. This allows larger, undigested food particles to sneak through the gut lining and into the bloodstream, a condition often referred to as 'leaky gut'. When nutrients aren't properly absorbed, it can lead to nutrient deficiencies, and in the long run, contribute to IBS. Science backs this up, showing that stress can indeed affect nutrient absorption, which underpins the importance of managing chronic stress for a happy and healthy gut.

But stress isn’t the only factor in IBS. Other dysfunctions and imbalances can lead to IBS-like symptoms and stress can just be the thing that puts your symptoms into full gear.

Other Factors Contributing to IBS in Women

Gut Microbiota Dysbiosis: Picture your digestive system as a delicate ecosystem. When the balance of bacteria in your gut is off, it can lead to symptoms like bloating and discomfort. For women, this imbalance is often exacerbated by fluctuations in hormones, which can influence gut flora directly. Managing dysbiosis through targeted probiotics or dietary changes can help restore balance and reduce symptoms.


Chronic Infections: Hidden infections such as Small Intestinal Bacterial Overgrowth (SIBO) can imitate or worsen IBS symptoms. For women, the link between SIBO and conditions like endometriosis, which also impacts gut health, can complicate symptoms. Recognizing and treating these infections can significantly alleviate discomfort and improve digestive health.


Medication Side Effects: Many women are prescribed a range of medications that can impact gut health, including antibiotics and NSAIDs. These can disrupt the microbial balance in the gut, exacerbating IBS symptoms. Being mindful of the medications you take and discussing potential side effects with your healthcare provider can help mitigate these impacts.


Food Additives: The modern diet, filled with processed foods containing various additives, can irritate the gut. Women with IBS might find relief by identifying and eliminating additives that trigger symptoms, focusing instead on whole, unprocessed foods.


Natural Ways to Support Your Body When Stressed

If you are struggling with stress and IBS symptoms, my first recommendation would be to focus on reducing as much stress in your life as possible! There are natural ways to support your body when you're feeling stressed that you can put into practice not only when you are stressed but all the time so your body becomes more resilient when you enter into those stressful times (because let's face it…we can’t also control our environment or life in general!). 

By introducing specific foods, supplements, and lifestyle changes into your daily routine, you can manage your stress levels more effectively and give your gut health a significant boost. Here are some strategies to support stress and IBS symptom:

  • Add Probiotic Foods: Starting your day with a bowl of yogurt or adding some sauerkraut to your meals can introduce beneficial probiotics to your diet. These foods help maintain a healthy balance in your gut, which can ease IBS symptoms and improve your digestive health.

  • Consider Supplements: B-vitamins are great for keeping your energy levels up and helping you deal with stress. Magnesium is another helpful supplement, particularly if you’re dealing with constipation, a common issue for those with IBS.

  • Lifestyle Tweaks: Regular physical activity can significantly lift your mood and improve your health. Getting enough sleep is also crucial, as it helps your body recover and manage stress better. Practices like yoga or meditation might also help you feel more centered and could lessen IBS symptoms by reducing stress.

  • Identify Food Sensitivities: Paying attention to how certain foods affect you can be really eye-opening. If you know which foods trigger your symptoms, you can avoid them and potentially feel a lot better. Keep in mind that avoiding certain foods isn’t a long-term solution - functional stool testing can help you dive deeper into why you’re experiencing those food sensitivities in the first place. 

  • Work with a Functional Nutritionist: If you’re finding it tough to manage stress or IBS symptoms on your own, consider seeing a functional nutritionist (hi!, I’m Taryn Mattern, a registered dietitian and functional nutritionist).
