If you suffer with IBS, then you know how frustrating this health condition can be. Odds are (since you’re reading this) you have been searching for better

solutions to this chronic health condition. Today I want to introduce you to what I call “The Big 3”…these are the 3 major systems that must be assessed and addressed if you suffer with IBS.

If you have seen a gastroenterologist, you probably didn’t get much help or guidance for your condition. I don’t say this as a slam or attack on that specialty; it’s just a fact. IBS is a functional disorder of the bowels and restoring normal function of the digestive tract is not your gastroenterologist’s specialty. I have yet to see a patient walk into my office that has had their IBS evaluated from a functional perspective by their gastroenterologist.  Most of the patients at my Naperville office have been told by their doctor to drink more water, take fiber/laxatives or try a probiotic. In most cases, IBS sufferers require more specific and comprehensive solutions than fiber or a probiotic.

IBS is a health issue that tends to respond well to a functional medicine approach. This is because IBS generally stems from one or more of what I call “The Big 3.” To properly assess and manage The Big 3, you may need the help of a functional medicine doctor.  Learn more about the nervous system, endocrine system and the immune system with respect to IBS below.

Endocrine System, Immune System and Nervous System: The Big 3 For IBS

The Big 3 are the 3 major regulatory systems of the body:

• Nervous system
• Immune system
• Endocrine system

Nervous System and IBS

As functional medicine doctors, Irritable Bowel Syndrome (IBS) involves intricate interactions between the nervous system and the gastrointestinal tract, known as the gut-brain axis. In individuals with IBS, there’s often dysregulation within this axis, leading to heightened sensitivity of the GI nerves. This heightened sensitivity can result in exaggerated responses to normal stimuli, manifesting as symptoms like abdominal pain, bloating, and bowel irregularities.  The autonomic nervous system, responsible for regulating involuntary bodily functions including digestion, also plays a crucial role in IBS. Imbalances within this system, particularly between its sympathetic and parasympathetic branches, can contribute to alterations in gut motility, visceral sensitivity, and digestive secretions—key features of IBS.

Furthermore, the central nervous system, particularly brain regions involved in pain processing and emotional regulation, can influence symptom perception in IBS. Psychological factors like stress and anxiety can exacerbate symptoms through their impact on the nervous system and the gut-brain axis.  Recognizing these complex interconnections underscores the holistic approach of functional medicine in managing IBS, addressing both physical and psychological aspects to promote optimal gastrointestinal health and overall well-being.

Your nervous system is a major regulatory system of your body; arguably the most important. Then you have the immune system; most of which if located in and around the digestive tract. Most diets used to manage IBS are targeting the immune system one way or another.

The Immune System and Irritable Bowel Syndrome

The immune system significantly influences Irritable Bowel Syndrome (IBS) through interactions with the gastrointestinal (GI) tract and gut microbiota. In IBS, there is often low-grade inflammation and immune activation within the GI tract, leading to increased intestinal permeability and immune responses, even without structural abnormalities. Dysbiosis, characterized by imbalances in gut bacteria, further exacerbates immune activation, contributing to symptoms like abdominal pain and altered bowel habits.

Additionally, stress, dietary factors, and environmental triggers can stimulate immune cells and inflammatory mediators, perpetuating inflammation in individuals with IBS. Understanding these immune-mediated processes is vital for developing targeted interventions to alleviate symptoms and restore gut health in IBS patients.

IBS and The Endocrine System 

Finally, we have the endocrine system; this is your hormone system and includes cortisol from your adrenal glands and other hormones such as thyroid hormones, estrogen, progesterone and testosterone. I would also like to make the point that you can’t have imbalances in only one of these system. This is because they all influence one another.

The endocrine system, which includes glands that produce hormones, can influence Irritable Bowel Syndrome (IBS) through various mechanisms. Hormones produced by the endocrine system can impact gastrointestinal (GI) motility, visceral sensitivity, immune function, and inflammation, all of which are factors involved in the development and exacerbation of IBS symptoms.  For example, hormones such as serotonin and melatonin, which are primarily produced in the gastrointestinal tract and the pineal gland, respectively, can affect gut motility and sensitivity. Imbalances in these hormones have been implicated in the pathophysiology of IBS, contributing to symptoms like altered bowel habits and abdominal discomfort.

Furthermore, stress hormones such as cortisol, produced by the adrenal glands as part of the body’s response to stress, can affect GI function. Chronic stress and dysregulation of the stress response system have been associated with the onset and exacerbation of IBS symptoms.  Hormones involved in regulating immune function and inflammation, such as cytokines and cortisol, can influence gut health and contribute to the inflammatory processes observed in IBS.  Overall, the endocrine system plays a multifaceted role in IBS, influencing various aspects of GI function and symptomatology. Addressing hormonal imbalances and dysregulation through a comprehensive approach, including lifestyle modifications, stress management techniques, and targeted interventions, is essential in managing IBS effectively.

By improving any 1 of them the other 2 improve and by the same token, damage to any one of them pulls the other two down.

They are like the sides of a triangle; all connected and each side influencing the shape and balance of the whole.

Why The Big 3?

Why would anyone want to focus on The Big 3? Well, what else would you focus on? IBS is a functional disorder; that means the problem is due to a lack regulation and normal function. The 3 major regulatory system are the nervous system, immune system and hormonal system.

Let’s look at 3 examples to get this point across:

Nervous system: stress can make IBS worse and the only way we can perceive stress is through our nervous system. The negative effects of stress originate from the nervous system. This system includes neurotransmitter imbalances in the gut and brain. Many with IBS also suffer with anxiety or depression…again nervous system.

Immune System: most of your immune system is located in and around your digestive tract. Your immune system is also a major source of inflammation. Some people with IBS respond favorably to diet changes and diet changes have a significant impact on the immune system. This is where testing food allergies or food sensitivities can be very helpful. Probiotics also impact the immune system.

Endocrine System (hormones): many IBS suffers notice their symptoms are worse during different times of the month (menstrual cycle) or when going on or off of hormonal birth control. It is common to see IBS develop in teenage girls when they begin to have menstrual cycles and during perimenopause and after menopause…again hormones shifts.

I could just keep going here making connections between The Big 3 and IBS but I think you get the point.

You really need to take 3 specialties and roll them into one…neurology, immunology, and endocrinology to appreciate the complexity of IBS.
