Individualized nutrition support to optimize your child’s health

Nutrition is a key part of any medical treatment plan. That’s why DMG Children’s Rehabilitative Services (DMG CRS) includes registered dietitians and pediatric nutritionists to support your family.

DMG CRS regularly treats pediatric patients affected by nutritional deficiencies/disorders, obesity, chronic illness, and eating disorders. Our pediatric nutritionists are industry experts specializing in the care of pediatric patients of all ages with a variety of complex conditions and unique nutritional requirements. Our areas of expertise include:

  • Feeding problems

  • General nutrition planning

  • Ketogenic diet to aid in the treatment of epilepsy

  • Special formulas

  • Tube feeding

  • Weight management

Your DMG CRS pediatric nutritionist will work one-on-one with you and your child to help you select appropriate healthy foods, vitamins, and minerals to improve overall health and target specific medical conditions. We also recognize the existence of cultural and familial eating preferences, and your pediatric nutritionist will incorporate such preferences in dietary planning programs.
