Hi,
Noted the history about your 18 year old son, trip to Algonquin park wherein he ate scary host ghost pepper tortilla chips and re-hydrated freeze dried foods which is he not new to, developed white stools and no other symptoms.
I can understand that there are no other symptoms but having white stools is not at all normal.
Hence I would advise at least the following things to make sure that there is no medical or surgical condition that cause white stool and are as follows:
Tests of stool particularly for stercobillin.
Urine tests for bile salts and pigments.
Blood tests particularly for full
liver function tests including that for
Alkaline Phosphatase and GGT, these help to see for any evidence of obstruction
jaundice that cause white stools.
Ultrasonography of abdomen to see for any gallstones in
gallbladder and bile ducts.
Clinical evaluation and examination.
All these help to know the cause.
If all the investigations are normal then nothing to worry about.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. T Chandrakant, ENT & General Surgeon
