<s>[INST] I am a 57 year old male. I am a 8 year survivor of pancreatic cancer stage 4. The tail of my pancreas (about 20% ) was removed 6-1/2 years ago. My blood glucose takes longer to come down after a meal. I am currently prescribed metformin 500 mg once daily taken in the morning. My readings are up to about 180 one hour after a meal, and back down to 85 to 105 three hours after a meal. Does this sound ok. [/INST] hi sir.since you had suffered from pancreatic cancer and your tail of the pancreas has been removed 6 and half years back. your pancreas may struggle to produce insulin so you may lead to diabetes metformin you are taking is to control your blood sugar levels. so you no need to worry about that. it's better to check HB a1c 3 months ones which shows the average blood sugar in a body for past 3 months and take medicines according to that if you are diabetic. air sugar levels in your blood may fluctuate since you take metformin so no need to worry about that thank you. </s>
