This begs the questions: If I don't have any symptoms of celiac disease, then: 

• How do I know I have it?
• How do I know if I should discuss it with my doctor?
• How do I know whether to get tested? 

Should I Get Tested for Celiac Disease? 

It may take up to four years for symptomatic patients to receive a diagnosis of celiac disease, which allows the disease to progress and potentially allow those serious complications to develop. If you have no celiac disease symptoms, it may take longer. 

So it's important to see your doctor if you suspect you have celiac disease. Even if it's not celiac disease, some symptoms may be signs of other problematic conditions that require medical attention. 

Other people who should be tested include those with relatives who have celiac disease, especially parents, siblings or children. Even those with distant relatives with the condition should see their doctor.
