Celiac disease is an autoimmune response that affects each person differently, with a lengthy list of over 200 known symptoms. The only treatment for celiac disease is to follow a gluten-free diet. It is important to not start a gluten-free diet before testing and diagnosis, as this can lead to false negatives on blood tests and endoscopies. Once gluten is removed from the diet, some people experience relief from symptoms within a few days, while others notice improvements within a month. The small intestine may heal completely within 3 to 6 months, but adults diagnosed at an older age could take up to 2 years to fully heal. The length of time on a gluten-free diet is positively associated with symptom recovery, with more men than women fully recovering from symptoms in one study.
| Characteristics | Values |
|---|---|
| Time to see results after diagnosis | Within a few days of starting a gluten-free diet, you should start to feel some relief from symptoms like fatigue and brain fog. Other symptoms may take longer to go away, but you may notice gradual but steady improvement. |
| Testing | A blood test is the first step. If the blood test is positive, an endoscopy with a biopsy of the small intestine is done. This is considered the “gold standard” for diagnosing celiac disease. |
| Testing after being gluten-free | If you cut out gluten before you get diagnosed and later want to test for this, you will need to go back to eating gluten daily for at least 6 weeks to get an accurate result. |
| Time to heal | The small intestine may heal completely within 3 to 6 months, though adults diagnosed at an older age could take up to 2 years to fully heal. |
| Time to see results | Most people with celiac disease experience some degree of relief from symptoms within a few days of completely removing gluten from their diet. |
| Effect of time on a gluten-free diet | The length of time on a gluten-free diet was positively associated with symptom recovery. |

What You'll Learn
Celiac disease is notoriously difficult to diagnose
The only way to diagnose celiac disease is to eat gluten and undergo testing. If you are already on a gluten-free diet, you should consult a gastroenterologist specializing in celiac disease. Doctors typically use blood tests and biopsies of the small intestine to diagnose or rule out celiac disease. During an endoscopy, a scope with a small camera is passed down the mouth, oesophagus, and stomach into the small intestine, where several samples are taken to look for damage and inflammation of the intestinal lining.
There is also a genetic test that can rule out celiac disease by testing for the genes associated with the disease (HLA-DQ2 and HLA-DQ8). However, it cannot confirm a diagnosis, only the likelihood of developing the disease. A genetic test is often used as a first step to determine whether further testing is necessary.
Symptoms of celiac disease vary widely and can include gastrointestinal issues, abnormal periods or fertility problems, mood changes, and dermatitis herpetiformis (a chronic skin condition also known as the "gluten rash"). Some people with celiac disease also experience symptoms that affect parts of the body outside the digestive tract. In some cases, a dentist may notice signs of celiac disease during an exam, as the disease can cause defects in tooth enamel or canker sores.
If you suspect you have celiac disease, it is important to consult a doctor before making any dietary changes, as this can affect test results. Once on a gluten-free diet, antibodies to gluten will start to drop in the blood, and the intestine will begin to heal, potentially leading to false negative results on blood tests and endoscopies.

The only way to diagnose celiac disease is to eat gluten
Celiac disease is a genetic disease that affects the small intestine. When a person with celiac disease consumes gluten, their body's immune system attacks the tiny bumps (villi) lining the small intestine, impairing nutrient absorption. The only treatment for celiac disease is to eliminate gluten from the diet entirely.
To diagnose celiac disease, healthcare providers must find evidence of intestinal damage caused by gluten consumption. This damage can be detected through an endoscopy, a procedure in which a small camera is inserted into the patient's mouth and guided down to the small intestine, where several samples are collected. This method is considered the "gold standard" for diagnosing celiac disease.
However, if a patient has already adopted a gluten-free diet, the intestinal damage may have begun to heal, leading to a false negative result on the endoscopy. In such cases, it is recommended to reintroduce gluten into the diet temporarily before repeating the test. The duration of this gluten challenge varies, with some doctors recommending at least a month, while others suggest at least three months to ensure accurate results.
For example, at the Mass General Center for Celiac Research and Treatment, patients are advised to consume at least a cracker a day for a month before an initial antibody test. In contrast, the University of Chicago Celiac Disease Center recommends half a slice of bread daily for 12 weeks before blood work and two weeks before an endoscopy. Therefore, it is crucial to consult a gastroenterologist specializing in celiac disease to determine the appropriate gluten challenge duration.
It is important to note that a genetic test can be used as an initial screening tool to rule out celiac disease, but it cannot confirm the diagnosis. The test can determine the presence or absence of the genes associated with celiac disease (HLA DQ 2 and HLA DQ 8). If an individual does not carry these genes, celiac disease is highly unlikely.

A gluten-free diet may provide relief from symptoms within a few days
Celiac disease is notoriously difficult to diagnose, with an estimated 80% of cases going undiagnosed. The disease affects each person differently, and has a lengthy list of over 200 known symptoms. Issues like fatigue, joint pain, and iron deficiency anemia are common in adults, while children and infants typically experience digestive symptoms.
If you think you may have celiac disease, it is important to consult a doctor before making any dietary changes. This is because the tests used to diagnose celiac disease require the patient to be consuming gluten. Once a patient has received a diagnosis of celiac disease, the only effective treatment is to follow a gluten-free diet.
After starting a gluten-free diet, some people with celiac disease may experience relief from symptoms within a few days. However, it is important to note that the time it takes to see results can vary. Some people may notice gradual improvements over time, while others may experience a more rapid change. For example, one person reported feeling significantly better after two weeks on a gluten-free diet, while another person did not notice any difference until about a month had passed.
It is recommended that patients with celiac disease work with a gastroenterologist, a dietitian skilled in the gluten-free diet, and a family physician to manage their condition. Strict adherence to a gluten-free diet and regular medical and dietetic follow-up can reduce the risk of long-term complications.
It is also worth noting that simply cutting back on gluten may not be enough for people with celiac disease. Cross-contamination with gluten can cause issues for those with the disease, so it is important to be vigilant about avoiding all sources of gluten.

The disease affects each person differently, and has a lengthy list of over 200 known symptoms. The only way to diagnose celiac disease is to eat gluten and then undergo testing. However, once gluten is removed from the diet, the intestine begins to heal, and testing may yield false negatives.
For this reason, it is recommended that those who suspect they may have celiac disease consult a doctor before cutting gluten from their diet. If you have already cut gluten out of your diet, you will need to reintroduce it for at least 6 weeks to get an accurate result.
Once a diagnosis is received, the only effective treatment is to follow a gluten-free diet. The sooner gluten is removed from the diet, the sooner relief from symptoms will begin. Some people report feeling better within a few days or weeks, while others notice a gradual improvement over a longer period of time.

The small intestine may heal completely within 3 to 6 months, though adults diagnosed at an older age could take up to 2 years to fully heal.
The length of time on a gluten-free diet is positively associated with symptom recovery. A survey of Canadian adults with celiac disease found that the percentage of respondents reporting full recovery was significantly higher among those who had been adhering to a gluten-free diet for longer. Therefore, strict adherence to a gluten-free diet is necessary for the treatment of celiac disease, and the longer you stick to the diet, the more likely you are to recover.
