HI, My father is diabetic since 25 yrs, his current sugar levels are 160-210. His creatinine is 2.4. Since last 3-4 days, he is having high pain in stomach and upper abdomen. He is not able to digest anything, and feels Nausea whenever he try to eat anything. He is also having continuous hiccups. He is even not able to drink anything. Can you please suggest what could be the reason. We have consulted 2 doctors in last 4 days not there is no relief in pain and digestion.
