Hi lisajankus, welcome to HCM
First of all your chills with running nose and abdominal symptoms are not inter-related, they are two different entities.
, loss of apettite, belching
were all features of Gastro esophageal Reflux disease
. These features combined with with diarrhea
may be irritable bowel syndrome(IBS) or Gastroenteritis
. Since you have mentioned that it is only mild diarrhea for two days IBS is unlikely...
However if these symptoms persist you should do an ultrasound
abdomen to look for Liver and Gall bladder
abnormalities which may also produce these symptoms..
Wishes for your good health,
