my 4yo was taken to hospital with severe stomach pains after ruling out appendix and passing some smelly wind symptoms subsided and we left. Since then he has had stomach pains re-occur and now at every meal. He has lost his very good appetite and has lost a lot of weight. his stools are very pale and loose and has had a few problems with urgency and loss of bowel control. He has a history on his fathers side with stomach and bowel cancer.  I am wondering if I should have him tested for mesenteric lymphadentitis and if this may be due to viral infection like hepatitis. his immune system seems to be rather poor showing not much resistance to infections.
Hello and welcome to Chat Doctor, The presence of abdominal pain, loss of appetite, loss of weight, pale stools suggest disease process pertaining to liver. You need to get liver function tests done. These symptoms could be due to hepatitis, however, the diagnosis can be made after investigations only. Urgency occurs in infection of the urinary tract. Get a urine examination done - routine and microscopy to look for any evidence of infection. If infection is present, appropriate antibiotics need to be taken. Loss of bowel control could be due to loose stools and before getting any investigations done, you need to consult a pediatrician for clinical examination. Thanks a take care Chat Doctor.
