There is a huge fad component to the gluten-free movement.
However, many people genuinely cannot tolerate it, even without celiac disease.
The problem is they don't realize it and then live with the symptoms as though it's normal.
This article looks at the most common signs and symptoms of gluten intolerance.
Celiac Disease vs. Gluten Intolerance
First, it's important to understand the difference between celiac disease and gluten intolerance.
Celiac disease is an autoimmune disease triggered by gluten.
Even tiny amounts of gluten will severely damage the small intestine of an individual with celiac disease.
A gluten intolerant individual can typically eat small amounts of gluten safely, but experiences health issues when their threshold is exceeded.
The following are common signs and symptoms of gluten intolerance, after celiac disease has been ruled out.
Summary: Gluten can physically damage the small intestine in those with celiac disease. A gluten intolerance or Non-Celiac Gluten Sensitivity, is a more subtle sensitivity diagnosed after exclusion of celiac disease.
1. You Have an Autoimmune Disease
An autoimmune disease is the term given when your immune system mistakenly attacks and damages your own tissue.
There are more than 80 types, characterized by which tissues or organs in the body are damaged.
Gluten intake is consistently linked with numerous types, but whether it's the cause remains to be seen. It's influence in Celiac disease is the obvious example, but research indicates gluten likely affects Hashimoto's hypothyroidism and Graves' disease, to name a few.
In any case, it seems gluten intolerance is more likely in those with an autoimmune condition.
2. You Have a Known Food Intolerance
Food intolerance (or food sensitivity) is said to affect up to 10 percent of people.
A reaction occurs when an individual's threshold to particular food chemicals or compounds is surpassed.
Anecdotal evidence indicates it is quite common for someone with a food intolerance to also be highly sensitive to gluten.
Note that those who don't tolerate gluten-containing foods (but don't have celiac disease) should also consider FODMAPs as a trigger for symptoms.
3. You Always Experience Abdominal Pain and Bloating
Abdominal bloating is characterized by tightness and/or swelling in your abdominal region.
It occurs because of excess gas or disturbances in the muscles involved with digestion.
In a study of 59 adults with suspected NCGS, abdominal pain and bloating were the top reported digestive symptoms (5).
It's thought that a buildup of gas is the main cause in those who are sensitive after a gluten rich meal.
4. You Have Diarrhea on Most Days
Diarrhea is a common digestive symptom of food intolerance and potentially gluten intolerance too (6).
It isn't just uncomfortable though, as long term diarrhea left untreated can lead to dehydration and even nutritional deficiencies (7).
5. You Often Experience Rashes and Itchy Skin
Skin conditions associated with intestinal diseases are becoming more frequent.
New research suggests that NCGS can cause skin lesions similar both to eczema and psoriasis, particularly on the elbows, back of hands and knees.
In a study of 17 patients, a gluten-free diet greatly improved symptoms after just one month (8).
Research is in its early stages though and it's unclear if gluten is a direct cause of these conditions or simply worsens them.
6. You Consistently Have Joint or Muscle Aches
Chronic joint or muscle pain is a common symptom reported in studies of non-celiac gluten sensitivity (9).
The pain is said to be like that of Fibromyalgia, a condition which may be improved by going gluten-free, at least anecdotally.
As joint and muscle pain is a broad symptom, only consider it a possible sign if you experience several of the other symptoms.
Do You Have Any Signs or Symptoms of Gluten Intolerance?
Remember that a gluten intolerance only affects a small percentage of people.
That means going gluten-free only has health benefits for a select few.
But you may be one of them if you frequently experience one or more of the above signs and symptoms.
Always speak with your doctor or dietitian first before making any major dietary changes.

For the last five years, Chris Stevick has helped his wife Elaine in her battle against a vicious type of cancer that the couple believes was caused by Elaine's repeated use of Monsanto's Roundup herbicide around a California property the couple owned. Now the roles are reversed as Elaine must help Chris face his own cancer.
The last 50 years have been brutal for wildlife. Animals have lost their habitats and seen their numbers plummet. Now a new report from a British conservation group warns that habitat destruction and increased pesticide use has on a trajectory for an "insect apocalypse," which will have dire consequences for humans and all life on Earth, as The Guardian reported.

Pediatricians in New Delhi, India, say children's lungs are no longer pink, but black.
Our warming planet is already impacting the health of the world's children and will shape the future of an entire generation if we fail to limit global warming to well below 2 degrees Celsius (35.6°F), the 2019 Lancet Countdown Report on health and climate change shows.
