Background & Aims

Gastroparesis can lead to food aversion, poor oral intake, and subsequent malnutrition. We characterized dietary intake and nutritional deficiencies in patients with diabetic and idiopathic gastroparesis.

Methods

Patients with gastroparesis on oral intake (N = 305) were enrolled in the National Institute of Diabetes and Digestive and Kidney Diseases Gastroparesis Registry and completed diet questionnaires at 7 centers. Medical history, gastroparesis symptoms, answers to the Block Food Frequency Questionnaire, and gastric emptying scintigraphy results were analyzed.

Results

Caloric intake averaged 1168 ± 801 kcal/day, amounting to 58% ± 39% of daily total energy requirements (TER). A total of 194 patients (64%) reported caloric-deficient diets, defined as <60% of estimated TER. Only 5 patients (2%) followed a diet suggested for patients with gastroparesis. Deficiencies were present in several vitamins and minerals; patients with idiopathic disorders were more likely to have diets with estimated deficiencies in vitamins A, B6, C, K, iron, potassium, and zinc than diabetic patients. Only one-third of patients were taking multivitamin supplements. More severe symptoms (bloating and constipation) were characteristic of patients who reported an energy-deficient diet. Overall, 32% of patients had nutritional consultation after the onset of gastroparesis; consultation was more likely among patients with longer duration of symptoms and more hospitalizations and patients with diabetes. Multivariable logistic regression analysis indicated that nutritional consultation increased the chances that daily TER were met (odds ratio, 1.51; P = .08).

Conclusions

Many patients with gastroparesis have diets deficient in calories, vitamins, and minerals. Nutritional consultation is obtained infrequently but is suggested for dietary therapy and to address nutritional deficiencies.

General Study Design

The National Institutes of Health National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) Gastroparesis Clinical Research Consortium is a cooperative network of 7 clinical centers and a data coordinating center. The NIDDK Gastroparesis Registry, an observational study of prospectively enrolled patients with gastroparesis and gastroparesis-like symptoms who have met specific entry criteria, was begun in January 2007. Entry criteria for the Gastroparesis Registry included age 18

Patients

Of 396 patients with delayed gastric emptying in the Gastroparesis Registry, 376 completed the Block Brief FFQ. Of these, 49 (13%) receiving either total parenteral nutrition or enteral feedings were excluded because we did not have accurate caloric intake on these patients from their total parenteral nutrition or enteral feedings. In addition, 22 patients were identified with postsurgical or other causes of gastroparesis (eg, systemic lupus erythematosus, reflex sympathetic dystrophy),

Discussion

This report has examined dietary intake of patients with diabetic or idiopathic gastroparesis enrolled in the NIDDK Gastroparesis Registry using the Block FFQ to assess their food intake. This study has found that the majority of patients with gastroparesis consume diets deficient in calories, carbohydrates, protein, vitamins, and minerals. The dietary intake of patients with gastroparesis appears to be influenced by several factors, including etiology of gastroparesis, body weight, severity of
