Don't miss out on your appointment and if the symptoms continue to get worse get her examined by a physician right away, hopefully the white stools could be just a side effect from any medication taken, but the most common cause is the lack of the bile pigment which is secreted by the gall bladder, if this pigment isn't getting released to the digestive tract which gives stool their characteristic color, it could indicate a problem either with the gall bladder, the liver, or an obstruction of their conducts, that can also be the cause of the stomach pains, if you have any more questions by all means feel free to ask

Hi,

Thanks for writing to health care magic.

White color of the stool occurs in jaundice. What is the color of her eyes?

How is her appetite?
Is there any history of vomiting?

A fast heart beat could be because of various causes like anemia, arrythmias etc. A physical examination will help in identifying the cause.

Continue to ask further queries as required.
Hope this helps.
Take care.
