Seven Reasons a Brain Injury can Destroy Your Gut!

Seven Reasons a Brain Injury Can Destroy Your Gut

According to the CDC, incidence of hospital visits for traumatic brain injury have increased over the past decade.  It is one of the leading causes of disability world-wide.  You may know that the gut and brain are intricately connected but did you know that many people who experience brain trauma often experience resulting gut issues?   The gut problems come from alternations in the gut-brain axis or the communication network between our intestines and our cerebral matter.   When this delicate network is disrupted, it may result in dramatic gastrointestinal dysfunction, chronic pain or even disability.

According to Dr. Kharrazian, there are seven key ways in which traumatic brain injury can alter GI function, each of which may contribute to your chronic gastrointestinal disorders.

1. Autonomic Dysregulation - this occurs when the autonomic nervous system no longer appropriately  controls things that should come automatically, like heart rate, breathing, and gut motility.   If the system becomes overactive to a sympathetic stimulus the result may trigger a chronic pain loop that is hard to control, leading to abdominal pain.
2. Disorders of visceral sensing and processing - Visceral sensing is the gut's way of telling the brain what is going on.   Sensations in the gut such as temperature, pH, contractility communicate with the brain to notify the body what is happening in the digestive system.  Disruption of these sensing circuits is one of the main factors implicated in irritable bowel disorders (IBS).  Brain injury often contributes to a broken communication network between gut and brain.
3. Increase in intestinal permeability (leaky gut) -  After brain  injury the tight junctions that connect the cells that line your gut often become dysfunctional and allow large molecules to enter from the digestive tract into the blood stream.  Normally these tight junctions are protecting you from the large molecules, such as undigested food particles, bacterial parts or other luminal contacts that could cross over into the blood stream.  We know that the increase in intestinal permeability is a key factor in the development of autoimmune diseases, from Hashimoto's thyroiditis to multiple sclerosis.
4. Compromise of intestinal mucosa - Very commonly after brain injury, there is a compromise in the health of the mucosal lining.  We see this in patients in the Intensive Care Unit (ICU) as well... anytime the body is under massive stress, there is a tendency for the mucosa that lines the gut to atrophy and die.  The changes we see are often immediate and occur within minutes after brain injury, severe trauma or infection.
5. Breakdown of the blood-brain barrier (BBB) - The BBB, as it is affectionately known, protects your delicate gray matter from outside chemicals and inflammatory agents that may cause problems if allowed to enter.  After a brain injury, this barrier is often compromised, allowing massive inflammatory triggers inside the brain where they do not belong.
6. Brain Immune Dysfunction  - The Central Nervous System (CNS) controls much of the immune system and the production of inflammatory signaling molecules, like cytokines.  If there is an injury to the signaling mechanism it may contribute to either over-activation or under-activation of the immune system  This can lead to either immune compromise or autoimmune disease, where the body attacks itself.
7. Impaired gut motility - Sadly we see this as a factor in many disorders such as intestinal dysbiosis and SIBO (small intestinal bacterial overgrowth).   The impairment in smooth muscle contractility of the gut mucosa leads to dysmotility. This dysmotility leads stagnation  and alteration in bowel function and even malabsorption.  Ultimately patients may have very severe symptoms related to this problem of abnormal peristalsis in the gut.

Can see how these many mechanisms of action on the gut after brain injury may contribute to chronic pain and dysfunction, not only in the gut but the immune system as well?  Here's some simple things you can do to ensure you will maintain a healthy gut for life!

So What Can I Do to Maintain a Healthy Gut?

1. Eat a variety of colorful organic and local produce
2. Avoid genetically modified foods and glyphosate which contribute to a leaky gut
3. Take a daily multi-strain probiotic to support your microbiome and immune system
4. Eat prebiotic-rich fruits and vegetables to feed your healthy gut bugs
5. Protect your noggin!  Wear a helmet if you are skiing, biking or doing any activity that involves risk of head trauma
6. Try Restore, my favorite new product to restore gut health and heal tight junctions.  Call Amy at #303-993-7910 if you would like more info....

Although we cannot predict or even prevent a head injury, it's important to realize that if it does happen to you, your gut function may be affected.   Start NOW to take steps to develop a healthy gut microbiome in the meantime!

Are Your Gut Microbes Making You Fat!?

Are Your Gut Microbes Making You Fat!?

There are trillions if bacteria living in your gut, that we know.  But did you know that the population of your microbes may determine if you are likely to be fat or thin?! As we study this amazing microbe machine inside of us, we are discovering the many and far reaching implications of having a healthy population of bugs in your gut.

Researchers recently found pairs of human twins in which one was obese and the other lean. They transferred gut bacteria from these twins into mice and watched what happened. The mice with bacteria from fat twins grew fat; those that got bacteria from lean twins stayed lean. The study published in Science on September 6, 2013, describes the details.

It is becoming more clear that our microbial colonies play critical roles in health, with doctors now curing people by transferring microbe-rich tissues from healthy people into sick ones. Where the term "fecal transplant" used to sound like science fiction, there is now strong enough evidence of potential benefits that there are major medical centers performing this procedure to treat resistant clostridium difficile colitis infections.  Could they be transplanting gut bugs in the future to cure obesity? Sounds crazy but perhaps not too far fetched...

I don't know about you... but I'd rather change my diet than exchange fecal matter! Keep reading on for how diet can change your microbes, too...

There is a caveat: Microbes associated with leanness can’t take up residence in mice with “obese” gut microbes unless the animals eat a healthy diet.

As part of the study, the twins’ gut microbes were transferred into mice that had been raised in a previously microbe-free environment. The researchers had a chance to observe what happens when a mouse carrying a collection of gut microbes from an obese twin is housed with another mouse carrying gut microbes from the lean twin.

“Eating a healthy diet encourages microbes associated with leanness to quickly become incorporated into the gut,” said senior author Jeffrey I. Gordon, MD, director of the Center for Genome Sciences & Systems Biology at Washington University. “But a diet high in saturated fat and low in fruits and vegetables thwarts the invasion of microbes associated with leanness. This is important as we look to develop next-generation probiotics as a treatment for obesity.”

In 2009, Gordon found that the microbes in obese individuals also lack diversity and contain more pathogenic species. Individuals with healthy microbes contain a larger variety and include species such as provatella and bifidobacter. Earlier research showed that obese individuals had a shift from more Bacteroidetes to greater proportion of Firmicutes. Those that remained lean continued to have high levels of bacteroidetes. There is also evidence showing that these gut bug populations also change as we age.  Perhaps the most important idea from that past decade of research is that the diet we consume has the ability to change our internal mileau!  More industrialized nations tend to have gut populations that favor Firmicutes while less industrialized societies that still rely heavily on unprocessed food sources have guts that remain high in Bacteroidetes.

These observations were confirmed by a recent Danish clinical study that linked the risk for metabolic disorders – obesity, cardiovascular disease, and diabetes – to a shortage of friendly intestinal.  The microbiome of bacteria-poor people were dominated by species that cause chronic inflammation in the body.

The "good" guys vs. the "bad" guys ... 

The Firmicutes ("bad" guys) and the Bacteroidetes ("good" guys)  are divisions of gut bacteria. The microbiota of the human gut is dominated by these two species, most of which are benign although a few are pathogenic.

The Firmicutes is the largest bacterial class, containing more than 250 types, including Lactobacillus, Mycoplasma, Bacillus and Clostridium.  They are a very diverse class and Clostridium species are obligate anaerobes whereas members of Bacillus form spores and many of them are obligate aerobes. Streptococcus pyogenes, the well-known cause of 'Strep throat', is also a member of the Firmicutes.

The Bacteroidetes include about 20 types. In the human gut, Bacteroidetes is probably the most abundant single genus. Species of Bacteroidetes are obligate anaerobes that are benign inhabitants of the gut. However, they are opportunistic pathogens that can cause disease if they gain access to the peritoneal cavity outside the gut, for example in bowel perforation or surgery. In addition research raises the question of how consumption of increasingly hygienic and processed food deprives our microbiota from useful environmental genes and possibly affects our health.

Could Probiotics Help?

Probiotics are bacteria that help maintain a healthful balance of microbes in the intestines, and generally benefit their host.  The average person’s digestive tract hosts about 400 kinds of probiotic bacteria, which help prevent the growth of harmful bacteria and promote healthy digestion.  Now we know they may also affect our disposition towards being thin or obese!

Lactobacillus are often given to patients following a course of antibiotics, and are also found in yogurt and most other cultured/fermented foods.  Probiotics may be used in infants to populate the gut after c-section and may benefit babies with colic.  For more on probiotics and how they can benefit your health, read this!  I believe we are just on the edge of understanding how these healthy bugs and supplementation of different strains may affect health and disease and weight.  Stay tuned for the coming research and blog articles...

So What Should I Eat?

The Paleo Diet may be beneficial in reducing your risk of chronic diseases such as diabetes, obesity, heart disease and many autoimmune and inflammatory conditions. I frequently use the basic principles of the paleo diet to help patients re-learn how to eat healthy, maintain ideal weight, and feel fabulous! Perhaps the most important thing about it is that it encourages you to get back to whole delicious real food.  It will allow you to feel better, lose weight easily and maintain muscle at any age. I challenge you to give it a try for yourself for 30 days and see if it doesn't change your life!

Healthy Gut = Healthy You!

There is a microbial zoo living inside you, literally trillions of microscopic organisms―more than 10,000 different kinds of them―all co-existing with each other and you.

In fact they outnumber you ten to one and ninety percent of the genetic material, (DNA and RNA) in your body is not yours, it belongs to the bacteria that is located mostly in your gut, but some also live on your skin and even in your nose.

Exactly what those different life forms do has been the subject of some exciting research in recent years, and while a few of these organisms can sometimes wreak havoc with your system, the majority of these little "bugs" are good, helping you digest your food, stay protected from infections, and even keeping your immune system properly regulated to fend off autoimmune diseases like asthma, allergies, and diabetes.

The community of microbes living on and in your body is unique to you – like your fingerprints – and is now being regarded as a key contributor to your overall health.

More and more, science is finding that teeny tiny creatures living in your gut are there for a definite purpose. Known as your microbiome, about 100 trillion of these cells populate your body, particularly your intestines and other parts of your digestive system.

Although some of these bacteria can make you sick, the majority are good, and they work together as to aid your digestive system and keep you well. Beneficial bacteria, better known as probiotics, along with a host of other microorganisms, are so crucial to your health that researchers have compared them to "a newly recognized organ." We now know that your microflora influence your:

• Immune system function
• Brain development, mental health, and memory
• Obesity
• Genetic expression 
• Risk of diseases, including autoimmune disease, cancer, diabetes, and autism

According to the featured article in Time Magazine:

"Our surprisingly complex internal ecology has been a hot topic in medicine lately. Initiatives such as the Human Microbiome Project, an extension of the Human Genome Project, have been working tirelessly to probe potential links between the human microbiota and human health, and to construct strategies for manipulating the bacteria so that they work with us rather than against us.

...They've been linked to a range of nasty conditions, including obesity, arthritis, and high cholesterol. Now, two newer areas of research are pushing the field even further, looking at the possible gut bug link to a pair of very different conditions: autism and irritable bowel disease."

Most people, including many physicians, do not realize that 80 percent of your immune system is located in your digestive tract, making a healthy gut a major focal point in your efforts to achieve optimal health. In fact, the root of many health problems is related to an imbalance of intestinal bacteria.  

The beneficial bacteria in your gut has actually been found to help prevent allergies by training your immune system to distinguish between pathogens and non-harmful antigens and respond appropriately – and this may be one reason why they also appear so beneficial in conditions like allergies, asthma, and eczema

 Like it or not, the bugs in your gut have a lot to say about your health!  This is why I frequently test patients gut function for common complaints such as fatigue, migraines, mood disorders, depression, anxiety or insomnia, ecezma, allergies, asthma, autism, and even trouble with concentration & memory.  Getting the gut bugs back into proper balance is critical to your overall health and especially the health of your immune system.  The simplest way to jump start your overall health is pay attention to the gut...  Eliminate sugar and refined flours from your diet and add a high dose probiotic to you regimen.  You'll be well on your way to a happy and helpful intestinal "zoo"!

Tips for Dealing with Herxheimer or Die-off Reactions

Dealing With Yeast Die-Off (Herxheimer) Reactions

  

Yeast overgrowth can happen in response to improper diet, poor immunity, difficulties in digestion and antibiotic use. Poorly digested food can lead to putrefaction (rotting) and encourages the growth of organisms.  Antibiotic use destroys the normal balance of gut flora and leaves an open field for bad bacteria and fungi to move in.  Hormones and steroids can make this condition worse, too.  Most importantly, over-consumption of simple sugars & refined carbohydrates will feed the yeast.  If the immune system is weakened or there are not enough probiotic ("good" bacteria) to combat the yeast, then it begins to grow unchecked and cause symptoms, such as "leaky gut".

In this blog, I am addressing specific patients who are being treated for fungal dysbiosis (yeast overgrowth), who may experience a worsening of their condition after starting a program for yeast control. This may be very unsettling & discouraging if it is not understood.  It must be addressed effectively in order to avoid worsening symptoms. Here are some strategies to minimize the chances of suffering unnecessarily from a Herxheimer (die-off) reaction.

Common Symptoms of yeast die-off include:

Fatigue, brain fog, gastrointestinal distress such as nausea, gas, bloating, diarrhea or constipation, low grade fever, headache, sore throat, body itch, muscle and joint soreness or pain, flu-like symptoms. Other symptoms include: lethargy, intense sweet cravings, rashes, irritability, joint stuffiness, or muscle pain. In susceptible individuals with pre-existing neurological symptoms such as hyperactivity, irritability, tantrums, and difficulty concentrating, their symptoms may temporarily intensify.

Yeast die-off reactions are not necessarily a sign that yeast treatment is succeeding. It may be an indication that yeast cells are dying in large numbers, and an indicator of the body's toxic overload. At that point, more poisons are being released than the body can adequately cope with at one time and may be a sign the system's elimination pathways (liver, kidneys, & bowels) are overburdened or blocked (as in constipation or liver congestion)

If properly undertaken, treatment for yeast related health problems should not lead to severe yeast die-off reactions.  Patients with elevated heavy metal levels may more problems with “die-off” symptoms

Strategies to minimize discomfort & shorten duration of die-off reactions

·       Reduce the dose of anti-fungals: Some patients may have to stop altogether for a few days. Dr Jill will generally start doses slowly and increasing them over time to help you deal with the possible die-off symptoms

·       Enzymes: Adding enzymes with meals may improve the digestion of foods and limit putrefactive short chain fatty acids with enzymes.  Use pancreatic enzymes, NOT fungal or plant based enzymes.

·       Stay hydrated:  Dr Jill recommend 4-6 fluid ounces of warm water every forty-five minutes, throughout the day.  Mineral water may help, too!

·       Get your sleep:  It is imperative to rest when experiencing yeast die-off reactions – 8-10 hours per night is essential.

·       Neutralize toxins:  There are ways to neutralize fungal toxins. Dr. Jill may recommend molybdenum, biotin, pantethine or liver support to accomplish this.  Activated charcoal may also help.

·       Alkalinize:  You may buffer the toxins by taking alkalizing agents immediately upon experiencing die-off symptoms. Such products as AlkaSeltzer Gold. Drinking mineral water may also help.

·       Antioxidants:  Provide extra antioxidants to quench the oxidative reactions created by the toxins.  Dr Jilll may prescribe vitamin C, Vitamin E or A, alpha lipoic acid or N-acetylcysteine.

·       Sauna & baths:  If you have access to a sauna, begin slowly (15 minutes per session) scrub all skin surfaces with a stiff brush and shower immediately afterwards. Another helpful detox regimen is Epsom salt baths – use 3-4 cups in hot bath and soak for 20min every night.

·       Keep your bowels moving:  You must address any issues with bowel elimination if you have constipation – if you are not eliminating, you will reabsorb any die-off toxins being released! 

More remedies for constipation:

·       Use magnesium citrate 500-1000mg daily or until normal, soft bowel movements 1 or more X daily.  You may also add Ascorbic Acid 5-10grams daily to bowel tolerance.

·       Start every morning with a tall glass of warm water.  8 oz of coffee may also be helpful.

·       Try a few tablespoons of extra virgin olive oil, several times daily on an empty stomach.

·       Mix 2 TBSP of ground flax or chia seed into water & stir , let sit for 10minutes, stir & drink on an empty stomach.

Low SIgA and why it matters to your gut health!

What is SIgA?

IgA is a type of antibody that protects against infections of the mucous membranes lining the mouth, airways, and digestive tract... it is your first line of defense on the mucosal lining and it makes up a majority of your entire immune system.

Some people have a genetic deficiency and present with low levels of SIgA and frequent infections.  Others acquire a low level after their intestinal tract becomes over-run with abnormal microbes.

SIgA helps to shape the composition of the microbes in your gut!

Extraordinary amounts of immunoglobulin A (IgA) are produced in your intestinal mucosa daily, it is known as SIgA and is secreted into the human gastrointestinal tract. SIgA production is driven largely in response to mucosal antigens (bugs or food) encountered by gut-associated lymphoid tissue (GALT).  It is clear that secretory antibodies are directed against at least two broad classes of antigens. The first is associated with enteric pathogens (the "bad guys" or infections) and their virulence factors, or things that the bugs secrete, like toxins.


The second broad class of antigens recognized by SIgA is associated with the intestinal microbes or commensal microflora (the "good" guys, like probiotics). In experimental animal models commensal bacteria are potent inducers of secretory antibodies; in humans, it is estimated that between 25 and 75% of intestinal bacteria are coated with SIgA.  This could explain why one of the most basic ways to improve levels of SIgA is to give a patient probiotics and saccromyces boulardii. 

There is also evidence from mice that secretory antibodies play an important role in shaping the composition of the intestinal microbiota, which in turn can influence your gut's defense against invaders and enhance resistance to the intestinal infections.
  
Profound Role in Intestinal Balance and Your Health

So because SIgA can neutralize the "bad guys" and shape the "good guys" SIgA plays a profound role in intestinal balance and health.  SIgA is the main immunoglobulin in mucus secretions. The intestinal cells produce about 2-3grams of SIgA every day!  And production tends to peak in childhood and start to decline after about sixty years old.

This is our first-line defense against gut pathogens like bacteria, food proteins, parasites, fungi, toxins and viruses. SIgA antibodies prevent micro-organisms, food proteins and cancer-causing substances from binding to the surface of absorptive cells. Effectively, they attach themselves to invading bugs and trap them in mucus to prevent them from going anywhere!

The antibodies also 'tag' foods as acceptable to the body and this suggests why low SIgA levels can be a factor in developing and progressive food allergy and intolerance. Intestinal permeability is also related since, if levels are low, repair of mucosal tissues can be compromised.  This is often referred to as Leaky Gut and can coexsist with low levels of SIgA.

Certain SIgA antibodies have been shown to directly quench bacterial virulence, whereas others help with uptake of SIgA–immune complexes by mucosal dendritic cells and result in down regulation of pro-inflammatory responses normally associated with pathogens and allergic antigens.

In fact it is becoming increasingly evident that human health is inextricably linked to the gut microbiota, intestinal homeostasis, and mucosal immunity. IgA is at the centre of this dynamic. 

Testing your SIgA

Secretory IgA is quite independent of blood IgA levels so just because one is normal, doesn’t mean the other is.   SIgA can be measured in different ways, including stool and saliva. Levels can turn out to be low or high. Stool measurements have traditionally been based on sample extractions from animal models – it is hard to ask a mouse to spit! Salivary samples provide a systemic overview of circulating SIgA.

Ongoing low levels can help to explain why people can’t shift an immune problem like allergies, chronic skin conditions or infections. It can also explain why they find it hard to get rid of a microbial infection, too. Celiacs and those with IBD can have low levels and chronic stress has a major effect on SIgA levels. Certain medications can lower levels – including anti-inflammatories.   Other factors  includeviral infections (like Epstein Barr viruses), poor nutritional status, food allergies, ongoing stress. Interestingly some studies have shown variations in levels with gender and age – male patients often have lower levels.
