What Kind Of Leaky Gut Test Should You Take

How Do You Know If you Have Leaky Gut? Ask Your Doctor For These Tests

By Jillian Levy, CHHC

Think you might have leaky gut syndrome, causing you to experience symptoms like arthritis, fatigue, headaches and mood changes? If so, you should strongly consider taking a leaky gut test.

Many health and nutrition experts agree that to a large extent, health really begins in your gut. Why? A large portion of your immune system actually resides within your gut , where billions of bacteria live . Your gut communicates with your brain to control things like appetite, mood and stress levels plus it helps control your bodys ability to defend itself from sickness.

When your gut is healthy, it remains tightly sealed, in essence, carefully keeping toxins and waste within the digestive tract where they belong instead of spreading throughout your body.

Leaky gut syndrome, a condition that occurs when the gut lining becomes abnormally permeable , is diagnosed when tiny gateway openings develop between your intestines and bloodstream, allowing things to pass through that are normally blocked like toxins, undigested food particles and other harmful substances.

  • Autoimmune reactions and diseases
  • Changes in mood, weight and appetite

Food Allergy And Food Sensitivity Testing

We use very comprehensive blood testing to detect food allergies and food sensitivities that can be the cause of inflammation in the gastrointestinal tract as well as the cause of symptoms/conditions elsewhere in the body.

Certain foods can have the same effect as toxins in some people. We use very comprehensive blood testing which use very sensitive testing for more accurate results.

Gut Microbiota And Leaky Gut Syndrome

The intestines are also home to a wide range of bacteria called gut microbiota. These bacteria aid digestion, protect the intestinal wall and support normal immune function. LGS may involve imbalances in gut microbiota.

According to a 2016 article, imbalances in the gut microbiota can trigger the bodys immune response. This results in gut inflammation and increased intestinal permeability . IP describes how easily substances can leak out of the intestines and into the bloodstream.

Experts still do not know exactly why autism develops. However, scientists have suggested that various genetic, biological, and environmental factors may play a role.

Recently, scientists have begun investigating a possible link between gut microbiota, IP, and autism.

Leaky Gut Syndrome: 7 Signs You May Have It

If youve been around the natural health world very long, youve probably heard of a condition known as leaky gut syndrome. It sounds pretty gross, but its an important enough problem to consider. There are several leaky gut symptoms to be aware of, which is particularly important since leaky gut is associated with dozens of related conditions and diseases.

As more Americans are affected by poor diet choices, chronic stress, toxic overload and bacterial imbalance, it appears that the prevalence of leaky gut has reached epidemic proportions. The medical profession is just now agreeing this condition may even exist, which is especially shocking to me because intestinal permeability has been discussed in the medical literature for over 100 years!

Why should leaky gut syndrome concern you? Recently leaky gut has been called a danger signal for autoimmune disease. If youre wondering if you may be experiencing leaky gut, the first thing to do is access your symptoms. Keep in mind that its very common for people on a Standard American Diet to struggle with poor gut function and high levels of inflammation but just because digestive issues and autoimmune conditions are common doesnt make them normal!

Nourish Your Intestines To Promote Friendly Bacteria

Leaky gut

Remember yeast? Its just one of the microorganisms that can overdevelop and lead to increased permeability of the intestines.

You can learn how to fix a leaky gut by defeating them in number and quality: eat fermented foods.

Fermentation is actually a natural process that happens in the intestines when they break down sugar. Bacteria can then dine on them.

When you have gut issues, its possible you have more of the bad microorganisms than the good ones. What you need to do is nourish them by eating fermented foods.

Here are some of your options:

  • Yogurt
  • Tempeh
  • Miso

Note: Many grocery stores now offer instant versions of these foods. Make sure to check the label as some of them may contain a lot of artificial sugar.

Other Types Of Antibody Testing

In addition to testing for zonulin antibodies, other types of antibodies are being used as indirect measures of gut permeability.

These include:

  • LPS antibodies: Lipopolysaccharide is a type of sugar found on the cell walls of some gram-negative bacteria. LPS molecules are released when the bacteria die, but since they are relatively large in size they do not normally pass through the lining of the small intestine. However, when the gut is leaky some LPS can pass between the cells and stimulate the immune system. Therefore, the presence of LPS antibodies in the blood is an indirect marker of gut permeability .
  • Occludin antibodies: Occludin is one of the proteins that make up the tight-junctions between enterocytes. If occludin breaks down, the gut becomes more permeable, and if occludin fragments cross the intestinal barrier, they can stimulate the immune system to form antibodies against them. The presence of occludin antibodies in the blood suggests leaky gut .
  • Actomyosin network antibodies:Similarly, actomyosin proteins are found between the cells of the small intestinal lining and play a role in opening up the tight junctions. If the actomyosin network begins to break down and antibodies are formed, it suggests increased gut permeability as well .

Testing options:

It is important to note that any testing that involves antibodies can be blunted by steroids or immunosuppressants.

The Fundamentals Of Leaky Gut

A leaky gut is a popular term that describes a condition where the lining of the intestines is not functioning correctly. The correct medical term for leaky gut is increased intestinal permeability.

The intestinal lining covers a surface area of about 400 metres squared and requires about 40 per cent of the bodys energy expenditure. That is pretty extraordinary when you think that the brain needs only 20 per cent of the bodys energy expenditure.

This fact tells us that the intestinal lining is essential to our health.

The gut is a hollow tube that connects the mouth to the anus. So, everything that is inside of the gut is technically outside of the body. Therefore everything that is inside of the gut is not technically inside of the body.

Therefore anything that is in the gut to move into the body has to cross that intestinal lining. A fundamental function of the intestinal lining is to let in things that should get in and keep out things that should not stay out.

When certain conditions are present, the intestinal linings capability of doing that task breaks down, and then all kinds of problems can happen.

Many factors can interfere with the function of the intestinal lining including:

There are other factors which we call endogenous factors. Endogenous means they are factors that occur inside of the body that can contribute to leaky gut.

Endogenous factors include chronic inflammation, SIBO, or gut-brain axis problems

What Is The Best Test For A Leaky Gut

While Im focusing on the lactulose mannitol test here, its important to mention that it is not the only leaky gut test available. There are a few other tests that you may wish to try in addition to or instead of the lactulose mannitol test.

Lets take a look at other ways to potentially test for leaky gut.

Headaches Dizziness And Confusion


Beyond loss of taste and smell, doctors are noting a growing list of neurological effects in COVID-19 patients. Other indicators of the illness include dizziness, headache and confusion.

In fact, a study in JAMA Neurology found that more than 36 percent of 214 patients in Wuhan, China, experienced neurological symptoms during their bout of COVID-19. More recent research published in Annals of Clinical and Translational Neurology found that neurological manifestations headaches, dizziness, confusion, etc. were present in 42 percent of patients at the onset of COVID-19 symptoms and in 82 percent of patients at any time during the disease course.

For older adults, in particular, these neurological effects can be just as devastating as the pulmonary impacts of a coronavirus infection, says XinQi Dong, M.D., director of the Institute for Health, Health Care Policy and Aging Research at Rutgers University-New Brunswick. They can also be easily overlooked or dismissed as dementia or other diseases common with aging.

Were trying to be very vigilant and broad in our thinking when a patient comes into the emergency room with confusion or change in mental status, say Neal Sikka, M.D., an associate professor of emergency medicine at George Washington University in Washington, D.C. That could be some other type of infection it definitely could also be a presentation of COVID. And so we are trying to do rapid testing on those patients to identify them early.

What Is The Best Lab Test For Leaky Gut

Are you looking for the best lab test for leaky gut? The large majority of my patients have been to at least a few other doctors before they enter my office, many have been to specialists and as such, they have lab work that I can review. When people tell me that their labs are normal, with confidence I can assure them that likely someone didnt scrutinize the labs enough and that I will probably find a few things that will at least suggest a direction to go without spending more money on advanced labs often seen in functional medicine. Most people want a SIBO test or stool test, but they are often overlooking in my opinion, the best lab test for leaky gut.

Before we get to the best lab test for leaky gut, lets discuss the difference between functional lab analysis and pathological or conventional lab analysis. To do this, lets use the example of a common headache. Most people with frequent headaches dont have any abnormal lab values. Though, we know something is going wrong, overreacting or under functioning if you get headaches frequently. This means that further investigation needs to occur and more scrupulous inspection may benefit the patient.

Igg Food Intolerance Test

Why Its Important:

You need to identify any food sensitivities you have if you think you have leaky gut, since most people who have leaky gut wind up developing sensitivities as a result and ignoring these can make the condition even worse.

Why does leaky gut cause sensitivities and food allergies? When particles and toxins enter the bloodstream that normally shouldnt be able to, the immune system basically goes on overdrive, working hard to do what it thinks is beneficial for the body by raising immune responses. Intestinal hyperpermeability makes the body produce a high level of antibodies, with the hope of defending the body from dangerous particles.

This means the immune system is extra cautious and reactive, so it tends to negatively respond to foods that it used to tolerate better, especially things like gluten and pasteurized dairy.

While some food sensitivities or reactions are obvious, others are more subtle and can easily go unnoticed, since they produce whats known as low-grade systemic inflammation. This becomes dangerous over time and can cause a range of inflammatory diseases, so removing food sensitivities is critical to getting leaky gut under control.

Is Testing For Leaky Gut A Good Idea

In my opinion, a leaky gut is almost always a symptom of a deep-seated underlying issue, meaning that the underlying problem comes before a leaky gut.

Causes of a leaky gut may include any of above factors that interfere with the function of the intestinal lining.

One of the critical principles of functional medicine is that we want to get to the bottom of what is causing symptoms or even manifestations of a disease. We want to remove or address those causes or triggers before we try to do anything about the symptom or the sign. The more we can get to the root of the problem, the more effective the intervention will be.

In other words, by suppressing symptoms, it is going to be less effective, and will not last for as long because we have not addressed the underlying cause.

So with intestinal permeability, if we remove the triggers that are causing leaky gut in many cases, you will not need to address intestinal permeability because it will take care of itself.

One of the astonishing things about the cells in the gut is they regenerate every two to three days. Therefore if you remove the triggers that are causing the problem, the cells will revive and the tight junctions can restore themselves, and the intestinal permeability will disappear.

What Are The Risk Factors For Leaky Gut

3 Tests &  10 Symptoms Of Leaky Gut + My Favorite

While experts do not yet definitely know what causes leaky gut syndrome, there are various risk factors that can disrupt the gut microbiota and contribute to increased intestinal permeability. Some examples are:

  • Diabetes
  • Stress

With autoimmune disorders being a risk factor, the question of whether or not LGS is a cause or symptom of a disease like inflammatory bowel disease once again becomes relevant, since IBD is an autoimmune disorder.

How Do You Take The Lactulose Mannitol Test

The test itself is pretty easy and non-invasive. Here is how it works:

1. You will be asked to fast overnight and through the duration of your test. This means no food or drink after a certain time starting somewhere between 7 pm and midnight the night before your test and then for the 6 hours you are testing. Your medical provider or test supplier will let you know exactly what time you need to start fasting.

2. When you wake up the morning of your test, youll collect the urine from your first trip to the bathroom.

3. Next, youll drink the sugar solution for your test. Make sure you finish all of it.

4. While you wait for the sugar to make its way through your intestines, blood, and kidneys, youll be asked to drink some plain water . Typically, it is recommended that you drink at least 1L to make sure you have enough urine for the test to be accurate

5. Over the next 5-6 hours , youll either collect all the urine that you pass or youll collect a single sample at the 6-hour mark. This is a great time to binge that Netflix series youve been dying to watch because youre not going anywhere.

6. The test is finally over and you can eat again! Phew!

Once your urine samples have been processed, youll get the results. Typically, results take about a week to be ready.

What, exactly, do those results look like and how do you interpret them?

Gut Microbiota And Autism

2016 review , autistic children often develop significant digestive problems, such as constipation, diarrhea, and vomiting.

In a small 2017 study, researchers compared stool samples from two groups of children autistic children with GI symptoms, and those without autism or GI symptoms. The researchers identified significantly higher amounts of Clostridium perfringens bacteria in samples collected from autistic children with GI symptoms.

The Anatomy Of The Small Intestinal Barrier

Cells that make up the lining of the small intestine are called enterocytes.

They form a barrier between the lumen of the intestines and the rest of the body .

Their purpose is to regulate the absorption of vital nutrients and prevent anything dangerous from being absorbed into the bloodstream .

In a healthy gut, most molecules are absorbed THROUGH the enterocytes, processed as needed, and then passed on into the bloodstream .

This is called the transcellular pathway and is tightly regulated to keep out anything harmful .

However, some molecules, especially small polar molecules like water, can also pass between the intestinal cells directly into the bloodstream .

This is known as the paracellular pathway.
