The clinical charts of NCWS female patients attending the outpatient centers of the Department of Internal Medicine at the University Hospital of Palermo and the Department of Internal Medicine of the Hospital of Sciacca will be reviewed with a retrospective method. They had all been diagnosed with NCWS between January 2001 and June 2011 and included in a previously published study. These charts included specific sections for associated gynaecological disorders. Incomplete clinical charts will be excluded. All the patients will be evaluated at baseline (i.e. at diagnosis) and after at least a 6-months period of gluten-free diet.

To compare the presence and characteristics of gynaecological disorders in NCWS female patients, a control group of CD female patients had been randomly chosen by a computer-generated method from female patients diagnosed during the same period (2001-2011) and age- (+2 years) matched with the NCWS female patients. Similar to NCWS patients, also this control group was asked for gynaecological disorders and the answers reported in the patients clinical charts. All the patients will be evaluated at baseline (i.e. at diagnosis) and after at least a 6-months period of gluten-free diet.

To compare the presence and characteristics of gynaecological disorders in NCWS female patients, a control group of IBS female patients had been randomly chosen by a computer-generated method from female subjects diagnosed during the same period (2001-2011) and age- (+2 years) matched with the NCWS female patients. Similar to NCWS patients, also this control group was asked for gynaecological disorders and the answers reported in the patients clinical charts. All the patients will be evaluated at baseline (i.e. at diagnosis) and after at least a 6-months period of gluten-free diet.

The investigators prospectively will survey adult female patients with functional gastroenterological symptoms according to the Rome III criteria, and a suspected diagnosis of NCWS. The patients will be recruited between January 2017 and January 2018 at the same 2 centers. Most of the patients will be referred owing to gastrointestinal and extraintestinal symptoms, the onset of which, they reported, could be related to wheat ingestion. In addition, patients will be asked about the presence and characteristics of gynaecological disorders using an ad hoc questionnaire. All the patients will be evaluated at baseline (i.e. at diagnosis) and after at least a 6-months period of gluten-free diet.
