HI.
Thanks for your query.
The causes of pain in abdomen in a child for 4 months can not be
gastroparesis and there are no great reasons to have gastroparesis in such a young age.
The causes of nausea are anything that is not normal in stomach.
The causes of pain in a child can be as follows::
-Tummy tonsils- meaning enlargement of the lymph nodes of the abdomen.
-Appendicitis- by default this has to be ruled out in every case of pain in -abdomen of a child.
-Worms.
The best diagnosis is a high resolution
ultrasonography. some blood, urine and stool tests.
A therapeutic trial with a course of an antibiotic,
metronidazole and probiotics under the guidance of a
pediatrician / Surgeon always helps to solve the problem and to get a diagnosis.
Also given is a dose of medicines active against worms in intestine.
I hope a consultation with a Pediatric Surgeon, investigations and a course of an antibiotic and metronidazole should solve the problem.
If this is indicative of appendicitis , please go for the surgery of
appendectomy.
