“Mommy, I have a tummy ache.” It’s a sentence every parent will hear from their child sooner or later. Usually, with simple home care and rest, the tummy ache will quickly pass. But in some cases, stomachaches and other symptoms–such as frequent headaches, recurring nausea, diarrhea, dizziness, sweats and flushing–keep returning. Physical causes, from bacteria to viruses to food allergies or even lactose intolerance, are often the trigger. However, if the pediatrician has performed a thorough exam and found a child in good health, it’s possible that underlying anxiety is setting off the complaints.
