Nutritional approaches to GI disease (Proceedings)


CVC IN KANSAS CITY PROCEEDINGS




Dietary therapy plays such an integral role in the management of gastrointestinal (GI) diseases that it constitutes a part of the therapeutic plan in virtually every such case. Diet can be part of the diagnostic process as well, such as using an elimination diet in a dietary trial. It is beyond the scope of this discussion to address each disease of the GI system and the recommended diagnostic and therapeutic approach for each. Instead, we will consider methods for obtaining an in-depth nutritional assessment of each patient and developing an individualized nutritional plan for dogs and cats with different categories of GI disease to optimize the success (and avoid common pitfalls) of nutritional therapy.

The Circle of Nutrition


Table 1 Anatomic Localization — Small Bowel vs. Large Bowel Diarrhea
Animal Factors-consider the patient's signalment, lifestage, current body weight and body condition (as well as any recent changes in weight and BCS) physical exam findings, health, appetite, activity level and the environment. A detailed history of gastrointestinal signs, and laboratory results should be included help to localize the area and extent of GI tract affected. (see table 1).

Dietary Factors

Determine whether the current diet is home prepared or commercial product(s) including the form (moist semi moist or dry). If home prepared, obtain the recipe and amounts eaten. If the patient is fed a commercial food, examine the quality and availability of the diet. The food should be made by a reputable manufacturer, have a nutritional adequacy statement that it has undergone animal feeding trials for adult maintenance, have a nutrient profile matching the needs of this specific pet, and provide adequate dietary protein. Ask how long the patient has eaten its current diet. With GI disease, owners will often have attempted several diet changes on their own, or on the advice of staff from a pet food specialty store, their neighbour or the internet. Asking only about the current diet can be misleading and not reflective of usual intake. If the patient has undergone recent or frequent changes in foods, ask specifically about each diet used, (brand, flavor/type) as well as the response to each diet, and reason for change. Make sure to ask about type and amounts of additional dietary components, treats and supplements.

Feeding Management Factors

Ask how the food is offered and how often. Is it measured and how? Is intake observed? The availability becomes especially important in multi-pet households.

Once this assessment is complete, either a diagnostic plan is in place, or hopefully a diagnosis is pending. Sometimes, however the decision is made to perform a diet trial in lieu of diagnostics, as part of the diagnostics or as part of the therapeutic plan. Use your knowledge of localization of the disease, and the nutrient profile of the diet to formulation the nutritional plan for the patient. The nutritional goals should be to 1) meet the nutrient requirements for species, and lifestage with a complete and balanced diet 2) prevent or correct protein calorie malnutrition 3) improve or resolve clinical signs 5) correct any underlying nutrient deficiencies (ex. cobalamin in IBD) 6) potential for targeted nutrient to modulate the disease process.
