Hi,
I understand your concerns.
1.
Stomach cramps only after dinner could be due to
IBS. However,
upper endoscopy is advised to rule out gastritis/
GERD.
2. Experiencing upset stomach after drinking a large glass of milk might be also related to GERD/gastritis. To rule out
lactose intolerance, I advise to run the intolerance testing.
3. For the moment, I advise to:
- eat often and small portions
- avoid laying down/going to bed immediately after having your meal; especially when it comes to dinner (have your dinner at least 4 hours before going to bed)
- raise your head when sleeping
- avoid foods that would aggravate your symptoms: chilly, spicy, coffee, etc.
- start taking antacids after meal and PPIs in the morning
Hope it was of help!
