Hi,
Fever, vomiting and abdominal discomfort or pain constitute a
gastroenteritis syndrome. Considering that the child is generally unwell, the causes could be diverse. At 6 years of age, a bacterial infection and any cause of a surgical or
acute abdomen must be excluded. This shall be through a stool exam, culture and sensitivity tests. Depending on the state, an abdominal ultrasound could also be useful.
A complete blood and markers of inflammation also be useful indicators of the origin of the syndrome. A physical examination by a physician shall determine whether the child is dehydrated or not, not tenderness in abdomen if any and specify patterns and appreciate general patient outlook.
This examination compounded by a past medical history and other examinations shall be key in making a definitive diagnosis and drawing up an appropriate treatment plan.
I suggest you take the child to your family physician or
pediatrician for a proper evaluation for severe abdominal or surgical causes to be excluded.
Typhoid fever, shigellosis,
appendicitis or even ,malaria at times might mimic such clinical syndromes.
Thanks for your question and hope this helps,
Luchuo, MD.
