Probiotic Benefits for Chronic Fatigue Symptoms and Digestive Issues

Digestive system can be related to fatigue. Do probiotics help? Research is showing that probiotic benefits may include relief from chronic fatigue symptoms.

By taking advantage of probiotic benefits, you can help heal your leaky gut AND your chronic fatigue symptoms.

There’s nothing like suffering from debilitating chronic fatigue symptoms and digestive issues. Unfortunately, many people suffer from both. It’s not at all uncommon to be dealing with fatigue and bowel problems, like irritable bowel syndrome (IBS) simultaneously.[1,2] In this article, you’ll learn how probiotic benefits help chronic fatigue symptoms and can also help your digestion.

Gut Health and Fatigue Are Related

The association between gut problems and fatigue has been noted for years, but it wasn’t until very recently that researchers really started putting the pieces of the puzzle together, uncovering how abnormalities within the digestive system are related to fatigue and what can be done to heal both. Feeling chronically tired and also having digestive symptoms like abdominal pain, bloating, loose stools, diarrhea, alternating diarrhea and constipation, gas, and reflux means you likely have a “leaky gut” along with an overgrowth of “bad” gut microbial flora and too little healthy flora.[3,9]

Leaky gut is another term for increased intestinal permeability.  It is caused by a loosening of the tight junctions within the gut lining which form a barrier between the inside and outside of the digestive tract. It can be caused by any type of inflammatory process, including:

  • Infections with yeast, viruses, or bacteria
  • Long-term or very frequent use of antibiotics
  • Repeated use of pain-killers (NSAIDs) or alcohol
  • Long-standing psychological stress; extended exercise (athletes)
  • Food allergies or sensitivities, such as gluten sensitivity
  • insufficient intake of antioxidants

When any of these factors increase the permeability of the intestinal wall, unwanted bacteria, proteins, and other compounds can leak through. To deal with these foreign compounds, the body mounts an immune response, leading to more inflammation.

CFS and Gut Bacteria

Researchers have now found that if you have chronic fatigue syndrome (CFS), your body likely produces high levels of immune cells directed against the toxins given off by unhealthy gut bacteria—a sign of leaky gut and a cause of inflammation.[7] In fact, the severity of both chronic fatigue symptoms and digestive symptoms was found to directly correlate with the number of these immune cells directed against toxin-generating gut bacteria.

Probiotics are “friendly” microorganisms (typically bacteria or yeasts) that can live in the gastrointestinal tract or on other mucosal surfaces and have beneficial effects on human physiology and health. There are three general probiotic benefits which researchers believe may help in the treatment of leaky gut and chronic fatigue:

  1. They increase the numbers of healthy bacteria that live in the gut while decreasing the unhealthy bacteria;
  2. They improve the ability of the gut wall to act as a barrier to keep unwanted compounds out of the body;
  3. They decrease your body’s own production of inflammation-producing compounds, lowering inflammation in the gut and throughout the body.[3]

How to Choose a Probiotic

By taking advantage of probiotic benefits, you can help heal your leaky gut AND your chronic fatigue symptoms. But with literally thousands of probiotics on the market now, it can be nearly impossible to choose. To get the most benefit, look for a high potency probiotic with billions, rather than millions, of microorganisms. Ideally, you want to purchase the highest quality, most potent probiotic you can afford, one which uses human-sourced strains of both lactobacilli (for the small intestine) and bifidobacteria (for the large intestine) and has been proven to survive the harsh conditions of the stomach.

Fixing your digestion and improving the health of your gut is absolutely essential for total health and for healing from fatigue. But gut health is not the only factor that causes fatigue.

    Hello! interesting site! I really like it! Very, very good!

  • I stopped probiotics because I could not afford them. One month. I felt exhausted. I do have chronic fatigue and tomorrow I am getting them again. The best one for me is VSL 111. It’s 45$ but I will cut back on something else and would not stop taking them again. I take 2 a day. I do. Lost a bit from them but I would rather that than the chronic exhaustion. I hope this helps someone.

    Karen, keep it up. Look at healing your gut lining also. Very important and find out what foods are causing the damage…..often wheat, dairy, and then things like eggs, corn, soy. Good luck. My daughter has had CFS for 8 years….since she was 13. Very difficult.

    Also Karen, if you are in the USA check out a brand called Regactive. Can’t get it in Australia yet but it seems to aid glutathione production which aids in clearing toxins and thus assisting in better liver function, and more energy. Anyway….gooogle it. I am going to see if I can import some..but I doubt I will be allowed.

    Chronic Fatigue Syndrome is 100% undiagnosed Ehlers-Danlos Syndrome types the term CFS should never have been used & Fatigue is a symptom of EDS a connective tissue disorder a Born Genetic condition

  • I suffered with chronic for a year, and no supplements and vitamins and diet seemed to help. Finally I came across an obscure article about a woman describing how she used four different probiotics (to get a wide range) which helped her chronic illness. So I decided to try this. I happened to have four of the highly rated probiotics in my fridge. Within a few days, I was feeling a lot better. Months later, I’m finding that I need a continued intake of probiotics or else my fatigue gradually returns.

  • i meant suffered with chronic fatigue in the post above…

  • Hi Larry, Thats great news! what were the probiotics you had in your fridge? Thanks
