A follow up of a 10 year old in my practice revealed that constipation was the cause of her bellyaches. On miralax, she had bowel movements daily and her three times daily belly aches were completely resolved. Mom asked if there was an Over the counter fiber supplement her daughter can have. Here were my nutritional recommendations:
Minimize the milk and cheese intake, as they contain no fiber to help constipation and the casein part of cows milk, slows down digestion- almost bringing it to a grinding halt.
Use soy and almond milk instead if you want milk substitutes.
Increase your intake of insoluble fiber- from fresh fruits, peas, lentils, beans
Insoluble fiber, helps increase the transit time of your stool and keeps it moving along the intestinal tract.
