Patients should be referred to a dietician at diagnosis, and then have yearly check-ups to instruct and monitor their gluten-free diet adherence. Following the initiation of a gluten-free diet, there may be discordance between normalisation of immunoglobulin A-tissue transglutaminase (IgA-tTG) and mucosal healing.[104] Complete mucosal recovery takes varying amounts of time; less than half of patients with coeliac disease show normalisation of duodenal histology after 1 year on a gluten-free diet, with adults being less likely than children to show mucosal healing.[137] Symptoms are poor predictors of mucosal inflammation or recovery.[138]

If the patient is in clinical and serological remission after 1 year on a gluten-free diet, annual follow-up interval for the following 2 years may be considered, and then every 2 years thereafter.[23]

Patients should be prescribed oral supplementation to treat any nutritional deficiencies present at diagnosis, and should be monitored until deficiences are resolved.

IgA-tTG titres are typically checked at least three times in the first year following the diagnosis (3 months, 6 months, and 12 months), and then yearly as an indication of diet adherence.[23][105] In most patients, IgA-tTG titre should normalise within 6 to 9 months,[139] but it may take more than 3 years in some patients (e.g., children with severe mucosal atrophy, type 1 diabetes, and very high titres at the time of diagnosis).[140][141] No immediate action is required if the IgA-tTG titre is trending down, the patient is asymptomatic, and nutritional deficiencies are resolved.

Repeat endoscopy is not routinely necessary in patients who respond well clinically and in whom IgA-tTG has normalised.

Bone mineral density may be assessed in adults at the time of diagnosis, or after they have been on a gluten-free diet for 1 year.[23][55][132][133][142][143]
