<s>[INST] My son (9) just told me he was drooling uncontrollably during a bowel movement. I thought, Odd, but not particularly alarmed. On the other hand, he seemed rather disturbed that it happened. I suggested that it could simply be a bodily reaction to the relief he was feeling, but I would like to know more. [/INST] Hi, thank you for posting!I have gone through your query and I understand your concerns.In my opinion, your son's symptoms indicate that he suffers from hypersalivation, which may be a result of an abdominal disease, such as GERD (gastroesophageal reflux disease) or a liver disease.Your son need the following tests:- Abdominal ultrasound- Liver test- Complete blood count- Urine testYou should consult your gastroenterologist, in order to determine the right diagnosis and treatment.Hope this helped.All the best,Dr. Behar. </s>
