Engineers in the biomedical sciences may be able to fashion a gastric pacemaker as safe and effective for gastroparesis as cardiac pacemakers are for the heart. However, children and parents often forget that some bellyaches come from too much excitement or from worries. If there is only one symptom, the bellyache, then don't worry. Two or more symptoms, bellyache and fever, or bellyache and vomiting should be taken more seriously. In the absence of a second symptom, these two problems are likely to be functional, meaning they are expected behaviors for that age group, and are not a cause for alarm.
Dehydration is uncommon after toddler years.
In infants and toddlers, wait 30 minutes for the stomach to settle down after vomiting. Then give just one tablespoon of an oral rehydration solution made for this purpose. Offer mor rehydration solution every half-hour. Increase the volume by one tablespoon each time there is no vomiting. If your child cries but there are no tears, if his or her diapers are not wet after many hours, or if the lips and gums are dry, the degree of dehydration may be serious.
