Is gallbladder sludge linked to your gut bacteria?

Gallbladder sludge is an initial step in the development of gallstones. It causes many people pain but is arguably too early for surgery.  There are, of course, many natural ways to address this issue including a basic protocol, lecithin, and castor oil packs and research is indicating that probiotics might be helpful as well. While it stands to reason that a healthy digestive tract, i.e. one with a thriving colony of beneficial bacteria, will help protect against any digestive disease it is still nice to see the results on paper.

This study, published in the online journal PLoSOne, was actually conducted on different types of mice. These mice were from four groups of genetically related strains that were purchased from different vendors with a very different treatment of the mice in terms of their good bacteria. The researchers use genetically similar mice because genetics plays a role in gallbladder stone and sludge development so having similar genetics eliminates that variable and puts all the mice on an even playing field. The groups of mice differed mostly in their gut flora.  One vendor maintains the mice in a germ-free environment but doesn’t introduce any good bacteria. Another colonizes the mice with a healthy bacterial flora and then maintains a pathogen-free environment after that.

All of the mice were fed a “lithogenic diet”  meaning a diet that is known to induce gallstones. This diet was essentially similar to a high-fat human diet. Specifically 1% cholesterol, 15% triglycerides and 0.5% cholic acid (one of the components of bile – in humans we would produce this naturally). Results were based on gallbladder weight, the percentage of mucin (or mucus) in the bile, cholesterol crystal formation, sandy stone formation, and presence or absence of true cholesterol stones.




The study found that the mice with the good flora were more resistant to gallbladder sludge than the mice without the good flora. The total gallbladder weight was lower which is important because it represents a measurable way to test inflammation. Inflamed gallbladders grow thicker walls that have a higher content of immune cells and inflammatory particles.  Also the mice without the good flora showed higher percentages of mucin and researchers were able to determine that the good bacteria actually influence the gene expression of those mice.  Healthy gut bacteria is able to down-regulate the action of mucin genes, which contribute to mucus formation in the digestive tract.

Actual cholesterol crystal formation, sandy stone formation and cholesterol stones were also all significantly less in the mice with healthy gut flora.

What Does This Mean for Humans With Gallbladder Sludge?

Mice aren’t people, and although this is certainly something to think about, we can’t jump to the conclusion that gallbladder sludge can be prevented by good bacteria.  We can, however, use common sense to say that chances are having healthy digestive bacteria can help our bodies to maintain healthy digestion. That means that gut inflammation will probably be lower with good flora, there will probably be less mucus, and digestive processes will run more smoothly.  Logically it makes sense that this would lead to less gallbladder sludge formation.

How Do I Get Healthy Gut Flora?

Of course, there are a million probiotic formulas out there all claiming to be the “best” and as a consumer, it can be very difficult to wade through unless there is specific research on a specific product for the specific issue you’re having (which happens only in a handful of cases). There are not any products currently on the market which are researched for gallbladder sludge.  There are a number of ways to increase your good bacteria, many of which are from food.

Increasing Your Good Gut Flora

Your gut bacteria are 100 trillion friends you didn’t know you had. Take care of them!

  • Reduce Antibiotic Use. If at all possible, minimize or eliminate all antibiotics from your life.  Life-threatening illnesses are a different matter and some situations do require antibiotics but work with your doctor to minimize usage that is not absolutely necessary. Antibiotics kill off your good bacteria along with any bad bacteria and overuse is linked to obesity, serious digestive disease along with the more globally threatening antibiotic resistant bacteria.
  • Moderate Processed Foods. Processed foods are typically filled with preservatives, emulsifiers, stabilizers, colors and other chemicals that are foreign to your body and to your more fragile gut flora.  A whole food diet has been shown to foster a very different digestive environment than a processed food diet and so eating foods with fewer chemicals will help your host of tiny helpers.
  • Increase Dietary Fiber.  If you’ve read this blog before you probably know I’m a big fan of fiber. Fiber, especially soluble fiber, helps to feed the good bacteria and provides material for fermentation in your gut.  All of those good bacteria really like fermentation and need the “prebiotics” or bacteria food that the fiber provides.
  • Get More Fermented Foods. Naturally fermented foods like yogurt, kefir, sourkraut and other fermented veggies like spicy kimchee are all rich sources of good bacteria and can help to reintroduce those good strains into your digestion.
  • Grow Some (Organic) Veggies. Many of our good bacteria are soil microorganisms that we are supposed to through contact with, well, soil.  We are supposed to have these good bacteria from the earth and historically we would have got plenty of them by gardening, harvesting, farming and eating vegetables that aren’t “sanitized” before being put on grocery store shelves or irradiated to prevent foreign plant diseases from entering the country with produce. So growing some of your own or buying from a good local organic grower.  Rinsing your veggies as you normally would won’t eliminate all of the healthy bacteria so as long as they haven’t been sprayed with pesticides and herbicides they’re a great source of some of your most potent good flora.
  • Take a Supplement.  The supplements are always an option if that is easiest for you, but don’t forget to do some of the rest of it too. In terms of supplements, every digestive tract is different so it can be helpful to rotate through different types of products with different strains of beneficial bacteria because there isn’t a great way to predict which strains will colonize best in your system.

 

 



Your Microbiome: Are You Too Clean?

Your microbiome is getting a lot more attention lately, which makes sense because as of 10 years ago nobody even knew the word “microbiome” let alone had any idea why they should pay attention to it. Your microbiome, according to Joshua Lederberg who coined the term, is:

“The ecological community of commensal, symbiotic, and pathogenic microorganisms that literally share our body space.”

What that means in reality is that this is your population of bugs.  It’s the bacteria and microbes that populate your skin, your digestive tract, your mouth, ears, eyes, fingers, toes and genitals. It’s the community that makes up you. In fact, if you look at your entire body there are about 100 trillion organisms – that’s 100,000,000,000,000.  Essentially that means there are at least three times as many bacterial cells as human ones. Makes you think, doesn’t it?  Even without all the research, it follows naturally that just like your bacteria need you to survive, you need your bacteria to survive too.  Your microbiome helps you to protect yourself from harmful bacteria that might actually produce disease, help you digest your food, manufacture vitamins for you to absorb and generally maintain the health of your tissues. In fact there is a link between poor mixtures of bacteria in the gut and conditions like obesity, diabetes, rheumatoid arthritis, fibromyalgia and even some cancers.

So let’s talk about taking care of your microbiome – all those trillions of things are helping to protect you, so it makes sense that you should also protect them.  In this post we’ll talk about lifestyle factors and the next post will focus on the best diet for your community of trillions.




Keys  to a healthy microbiome:

  1. Get dirty already. There is a growing body of evidence that shows that modern standards of hygiene are linked to the increasing incidence of allergies and autoimmune disorders.  We don’t just keep clean, we actually make an attempt to ‘sterilize’ which is a horrible idea because if we actually managed it we’d probably die shortly thereafter. One of our major sources of new microbial material is simple soil – the earth from the place where you live.  This to me is a great reason to get out there and garden, to eat veggies from your garden straight out of the soil, and generally wallow around in the rich microbial environment that the earth has provided for us.
  2. Boycot the sanitizer. Of course it’s important to wash your hands if you’re exposed to people who have the flu or if you’re around a sick population, but wash with warm water and regular (not antibacterial) soap. Avoid the hand sanitizer, which typically contains toxic ingredients (like triclosan) and doesn’t actually help other than to encourage bacteria to develop triclosan resistance. So yes to normal hand washing as a way to prevent acute illness, but no to the overly-clean “sanitized” hands.
  3. Forget the antibacterial soaps. Not just do you not want to kill your bacteria, which sharply reduces the interest in anything antibacterial, there is also no actual benefit to most things labeled as antibacterial. Research studies have compared the effects of soaps and consumer products which claim to be antibacterial versus those which don’t and found literally no difference.  In fact, the FDA is currently taking a closer look at whether or not it is ethical for this labeling to continue.
  4. Skip the antibiotics unless they are absolutely necessary. Obviously antibiotics have a broad range of killing potential and that includes your healthy microbiome. Antibiotics don’t discriminate.  Obviously there is a time and a place where antibiotics could save your life and I am all for that use, but there is also a time and a place where your doctor hands you a prescription because they don’t feel right letting you leave the office without something in your hand, but it’s also probably not really useful for whatever you’re coming to see them for (like the ear infection). We also know that the effect of broad-spectrum antibiotics on your microbiome is long-lasting.
  5. Consider probiotics when you need them. Probiotics are basically packaged bacteria that are similar to the ones that make their home in your gut. If you’re in a situation where you had to take antibiotics or you had a stomach bug that might have knocked out the bacteria in your gut then it can be really helpful to replace those with a supplement.  Of course there are lots of different options for probiotics, and different ones are better for different situations so we’ll save the which-probiotic-is-best conversation for another day.
  6. Wear your probiotics with pride. It isn’t just your gut that benefits from beneficial bacteria, your skin is a colony too.  Fermented foods which contain bacteria similar to the bacteria in your gut can make a great topical treatment for a variety of skin imbalances.  There is a reason that yoghurt skin masks are so awesome.  Or kombucha toner. In fact, here are a couple of my favorite skin care recipes from my book, DIY Health: For Women.

Yummy Yogurt mask for dry skin:

1/2 Avocado
1 teaspoon yogurt
1 teaspoon honey
1 tbsp oatmeal

Protein Microbiome Tingler:
Leave this one on until it dries and it will refresh and renew your skin. The enzymes in the papaya and the probiotics in the kombucha eat away dead skin cells and replenish your skin microbiome and the raw egg firms up your collagen and connective tissue. You can always add a few drops of essential oil for additional pampering. Blend it up in the blender and apply to your face, decollete, or really any area that needs a little lift.

1 raw egg
1 tbsp kombucha
1/4 cup papaya

The bottom line is that if you’re fighting against your microbiome, or being generally  unfriendly with the sanitizers and wipes then it’s time to consider changing your tune and softening up your attitude towards your friendly helpers.  Without your microbiome, your life would be a whole lot harder so learn to love your own trillions of personal assistants.
