Hi,
Do you have any past history of
liver disease? Pale coloured stool can happen in liver disease(obstruction to bile flow), but in that case it will be associated with jaundice(yellow coloured eye ball) and yellow coloured urine.
In absence of these symptoms, this is probably just a reflection of diet change. This will be back to normal in a couple of days.
Burning in stomach and abdominal discomfort after eating indicates
acute gastritis, again from having the said change in diet.
For such cases, I used to give acid suppressants like
pantoprazole 40mg once daily along with antacids for 5-7 days. Your doctor will guide you.
Meanwhile avoid spicy/fried food items, take enough fruits and vegetables, and drink enough fluids. Also, avoid hot items.
Hope I have answered your query. Let me know if I can assist you further.
Take care
Regards,
Dr. Muhammed Aslam TK
