Sudden onset on abdominal, pain with fever and vomiting in child

Hello and welcome to e health forum.

More than one third of children complain of abdominal pain lasting two weeks or longer. Most likely, the symptoms could be due to either gastric acidity, peptic disease, constipation, intestinal colic, malabsorption syndromes, etc.

Night pain or pain on awakening suggests a peptic origin, while pain that occurs in the evening or during dinner is a feature of constipation. Children often deny heartburn, but other features of peptic disease include early satiety, nausea and the complications of gastroesophageal reflux.

The routine screening laboratory evaluation of abdominal pain in children includes a complete hemogram, ESR, liver enzymes, renal functions, Urinalysis, urine culture, stool test, etc. Based on the other findings, your daughter may need further tests including a stool culture, stool testing for parasites, or giardiasis, serology for H Pylori or amoebae and or a abdominal ultrasound. Carbohydrate breath testing for lactose intolerance can also be done.

You may consult with a pediatrician, who with proper history assessment as well as a physical examination can help in complete evaluation and specific treatment of your child's condition.
