Hyperglycemia, a sign of diabetes
The second major function of the pancreas is called endocrine, which means that it plays a role in “regulating the blood sugar level (glycemia) by secreting insulin in particular”, adds Prof. Crenn. This is why “an increase in blood sugar” can also be a sign revealing a dysfunction of the pancreas. “This sign can be asymptomatic or discovered on a symptom completely different from the pancreatic one”, he adds.
Lower back pain
Consistent back pain, especially in the lower part is somehow associated with pancreatitis and pancreatic cancer. In this case, the pain could also get worse if sitting or lying down, or some hours after eating.
