Hi. Thanks for your query. Noted the history and understood your concerns. Experiencing white stool like stool for 2 months after an acute and uneasy stomach in mid-August may not be related to drinking green tea. The most probable cause can be inadequate digestion secondary to chronic pancreatitis, pancreatic insufficiency or some intestinal condition that does not allow the food to stay in the small intestinal for long enough to be digested properly. Get the stool test done for three consecutive days. Upper GI Endoscopy and colonoscopy. Preliminary ultrasound of abdomen followed by contrast enhanced CT scan for hepato-biliary and pancreatic system may give the cause. Add pancreatic enzyme supplements with food and your problem may get solved. If there is an infection, get a course of an antibiotic, metronidazole and probiotics. Further management as per the findings on clinical evaluation and correlation with the reports of investigations.
