Question
Hello doctor,
I have symptoms: when I wake up in the morning, I have a bitter mouth and yellow substance in my mouth, sometimes I feel restless and shiver. I have lost weight and have abdominal pain above my navel. I went to an endoscopy and was diagnosed with antral gastritis but taking medicine did not reduce much. Doctor let me ask, what is a sign of a disease when waking up with a bitter mouth with abdominal pain above the navel? Thank you doctor.
