The two ways to manage the gastrointestinal symptoms associated with CSID are: *Diet modification that eliminates or restricts the consumption of foods containing<unk>  (table sugar) or starch sugars *The use of enzyme replacement therapy to replace the action of the<unk>  enzyme that is deficient. This medication requires a prescription from a doctor. Diet modification The level of ability to digest<unk>  or starch sugars is unique to each person who is living with CSID and depends on many factors, including the following: * The individual level of function of the digestive enzyme<unk> -isomaltase * How well the other functions of the gastrointestinal tract are working * How much<unk>  and starch sugars are consumed * If a person has any other health issues that may affect digestion For these reasons, a restriction diet needs to be specific for each patient who has CSID. Before making any changes to the diet, it is important for a patient to speak with a healthcare provider, especially if the patient is underweight or not gaining weight as would be expected. It is also advised that the patient work with a registered dietitian or nutritionist who can help identify the foods that can be tolerated and those that cannot be tolerated. A registered dietitian or nutritionist can also help the patient plan a diet that will meet the nutritional needs for normal growth and development. Vitamins, minerals, and additional supplements may be needed to meet all nutritional needs.
