The assessment of the personal care received is an indicator of the quality of the health care system. The diagnosis of celiac disease generates concern in the patient and limits the quality of life, and adherence to treatment determines symptomatic improvement. For this reason, a nursing consultation for health and nutritional education for celiac patients has been set up in our hospital. The objectives were to know the degree of patient´s satisfaction of this health program regarding technical and communicative aspects, as well as to assess the influence of adherence to the gluten-free diet (GFD) on health through clinical and analytical parameters. This is a descriptive cross-sectional observational study in patients diagnosed of celiac disease from January 2019 to June 2021 according to the Catassi criteria and who have attended the nursing consultation. Subsequently, the satisfaction survey was carried out and the clinical and analytical results were analyzed descriptively and statistically using the Student's t-test. The satisfaction of the nursing consultation was higher than 90%, highlighting aspects such as the clarity of the information, the interest and the kindness of the healthcare professionals. About 94.5% of the patients showed clinical improvement after the health education and the levels of hemoglobin, ferritin and vitamin B12 increased significantly in the analytical control after the GFD.
