Dr. Axe Leaky Gut Quiz

The permeability change must have caused every case of the illness

The two are associated, but the study alone may not show which came first or whether one caused the other

Treating permeability will necessarily cure the illness

Anyone with similar digestive symptoms has the same illness

They are interchangeable names for the same biological process

Food intolerance always results from an immune attack on intestinal cells

Increased permeability describes difficulty digesting one specific food

Permeability concerns barrier passage, while food intolerance usually refers to difficulty handling a food or component; one does not automatically prove the other

The combination confirms abnormal intestinal permeability

The symptoms are nonspecific and should be evaluated in context by a qualified clinician

Fatigue makes a digestive cause more certain than other causes

Improvement after avoiding one food would establish the diagnosis

Try a new elimination diet and reassess after several more days

Seek urgent medical help because confusion, fainting, and inability to retain fluids can indicate serious dehydration or illness

Wait for a routine appointment because these symptoms are expected with any gut problem

Use a home permeability test before deciding whether to seek care

To prevent every bacterium from living anywhere in the digestive tract

To regulate what passes from the gut into surrounding tissues and the bloodstream

To produce all enzymes needed to digest food

To move nutrients directly from the stomach into the colon

Increased intestinal permeability is studied in several conditions, but “leaky gut syndrome” is not a universally accepted standalone diagnosis

It is a single standardized diagnosis that explains most chronic symptoms

It is another medical name for any food intolerance

It can be confirmed whenever digestive symptoms improve after a diet change

Blood or black stool, severe abdominal pain, fainting, or signs of dehydration

Brief fullness after an unusually large meal

Occasional mild gas after eating beans

A temporary change in appetite during travel

They can conclusively diagnose increased intestinal permeability when symptoms improve

They make evaluation unnecessary when symptoms persist

They affect digestion only when laboratory tests are abnormal

They may support general digestive health, but they neither confirm nor guarantee a cure for a specific disorder

It occurs only in people with immediate food allergies

It proves that all irritable bowel symptoms begin with barrier damage

It has been documented in conditions such as celiac disease and inflammatory bowel disease, but it does not explain every digestive symptom

It is present whenever someone experiences bloating after a meal

Any permeability-related biomarker can identify the cause of digestive symptoms by itself

A commercial result is conclusive if it includes a numerical reference range

There is no single widely accepted standalone clinical test that definitively diagnoses every case described as “leaky gut syndrome”

Home testing is more definitive than a medical history and examination

Zonulin alone identifies which foods caused the problem

Any value outside a commercial reference range confirms a digestive disorder

The result proves that intestinal damage is permanent

Zonulin testing has important assay and interpretation limitations and does not establish a standalone diagnosis by itself

Tight junctions

Stomach sphincters

Villi alone

The gallbladder ducts

All probiotic products have identical effects because they contain live organisms

Probiotics reliably replace medical evaluation for persistent symptoms

A probiotic is proven effective if it changes digestion within one day

Effects can depend on the strain, dose, product, population, and condition, so broad universal claims are not justified

NSAIDs can affect the gastrointestinal lining, so medication use and symptoms should be discussed with a clinician

Stopping every medication immediately is the only appropriate response

The symptoms demonstrate a food sensitivity rather than a medication effect

NSAIDs affect only joints and cannot influence the digestive tract

Replace gluten with probiotics because both approaches provide equivalent evidence

Remove gluten for several days and use symptom improvement as definitive proof

Discuss testing with a clinician before removing gluten, because avoidance can affect celiac test results

Avoid only wheat while continuing other gluten sources before testing

Removing more foods always produces a clearer diagnosis

The diet cannot affect wellbeing because only medications influence digestion

Unnecessary restriction can reduce nutrient adequacy and food variety, so professional guidance may be useful

Any short-term symptom change proves the removed foods damaged the intestinal barrier
