Also known as secondary diabetes, type 3c diabetes mellitus (T3cDM) can accompany a condition called chronic calcifying pancreatitis (CCP). While acute bouts of pancreatitis usually cause temporary effects, chronic forms can lead to the development of scar tissue, which affects the function of the pancreas.
The pancreas serves many important functions in the body. Along with aiding digestion, the pancreas also produces insulin, a hormone responsible for managing blood glucose levels. As scar tissue forms within the pancreas, it will become less effective at generating insulin, which can lead to the onset of secondary diabetes.
Chronic pancreatitis can cause the following symptoms:
As for T3cDM, symptoms are similar to other forms of diabetes:
Many of these symptoms overlap with other medical conditions. Additionally, secondary diabetes can have other causes, including certain medications and hormone fluctuations. However, a doctor can confirm a diagnosis of CCP T3cDM with lab tests and diagnostic imaging.
Chronic pancreatitis is usually managed with lifestyle changes, enzyme supplements, and pain medications. When the condition is severe, surgery is recommended. Surgeons can remove all or part of the pancreas depending on how widespread the damage is. As for secondary diabetes, pancreatic enzyme replacement therapy can help with the output of insulin, although many patients will also need to administer insulin to keep blood glucose levels normal.
