<s>[INST] Hi, my daughter is 3 yrs old. I was called by her day-care center that she had an episode of pain in tummy and right after that she was very pale, weak and she closed her eyes for a couple of seconds. They gave her a biscuit and when I arrived 5 minutes later she was looking good. I saw that she didnt poo since yesterday and when we got home, she did. Then after that, she was active, played outside and full of energy. I dont think I need to take her to a doctor as I guess its from the constipation she had pain then I dont know if her blood pressure went low or her sugar. Can you please advice? [/INST] Hi Dear, Welcome to Chat Doctor. Understanding your concern. As per your query your child have symptoms of stomach pain. Well there can be many reasons for symptoms you mention in query like food allergy, gastroenteritis, electrolyte imbalance, acid reflux or systemic problems. Need not worry. For now avoid eating spicy food and also avoid seafood and nuts. I would suggest you to consult gastroenterologist for proper examination. Doctor may order endoscopy of esophagus, X-ray of upper digestive tract and ambulatory acidity test. Doctor may prescribe H₂ blockers, proton pump inhibitor along with antacid. Doctor may also refer you to allergy specialist or cardiologist if he/she find problem to be related with food allergy like seafood. Hope your concern has been resolved. Get Well Soon. Best Wishes, </s>
