Prediabetes and gastrointestinal (GI) symptoms; a cross-sectional study.

AIMS: Prediabetes associate with known micro and macrovascular complications of diabetes. Also gastrointestinal symptoms are present in diabetics higher than general population. The aim of this study was evaluation of gastrointestinal symptoms in subjects with prediabetes.

METHODS: This analytical cross-sectional study was conducted on 130 persons 30-65 years old, 65 pre-diabetic patients and 65 persons without glucose disorders from 2014 to 2015 in YAZD province. FBS and HbA1c used for diagnosis prediabetes. Demographic and medical history were collected. A questionnaire according to Rome III Criteria was used to collect digestive information (diarrhea, abdominal pain, constipation, abdominal bloating, heartburn, increased gas passing, nausea, intermittent diarrhea and constipation in the last 6 months ago). Frequency of GI symptoms in subjects with and without glucose disorders were compared. Data were analyzed by SPSS software Version 20. Data were reported as mean ± standard deviation or frequency and T-test, Chi Square and Spearman correlation coefficient tests were used. P-value less than 0.05 were considered statistically significant.

RESULTS: Higher frequency of bloating, early satiety, nausea, heartburn, gas passing and constipation are seen in the pre-diabetes group than in the control group; (p-value 0.0001, 0.0001, 0.0001, 0.0001, 0.001 and 0.0001 respectively). 96.9% in prediabetics had at least one gastrointestinal symptom, while in the normal groups 50% had at least one GI symptom (p-value: 0.0001).

CONCLUSIONS: Gastrointestinal symptoms were seen in prediabetics higher than healthy persons. So, prediabetes can not be considered an entirely benign and asymptomatic condition. Lifestyle interventions maybe necessary at this state.
