Fibrocalculous Pancreatic Diabetes (FCPD) is a rare type of diabetes that develops because of long-term (chronic) inflammation of the pancreas.
This condition is not related to alcohol use and is most often found in tropical regions, which is why it’s sometimes called “tropical pancreatic diabetes.”
FCPD is a specific form of Type 3c diabetes (also known as Pancreatogenic Diabetes) and usually affects younger, lean adults.
FCPD occurs when chronic pancreatitis — ongoing inflammation of the pancreas — leads to scarring (fibrosis) and the formation of stones within the pancreas. Over time, this damage reduces the pancreas’s ability to:
- Produce insulin (endocrine function), which controls blood sugar levels.
- Release digestive enzymes (exocrine function), which help break down food.
- Insulin therapy - most people with FCPD need insulin to control blood sugar, as the pancreas can no longer produce enough on its own.
- Pancreatic enzyme replacement - tablets or capsules help the body digest food and absorb nutrients properly.
- Healthy diet - a balanced diet rich in calories, protein, and vitamins is important to prevent weight loss and malnutrition.
- Pain management - medicines may be used to help control abdominal pain caused by chronic pancreatitis.
- Regular follow-up - ongoing care with your diabetes and gastroenterology team is essential to monitor blood sugar, digestion, and overall health.
Type 3c diabetes happens when the pancreas is damaged. Because the pancreas makes both insulin (to control blood sugar) and enzymes (to help digest food), treatment often needs to manage both problems.
Managing Blood Sugar
- insulin injections are often needed, as the pancreas may not produce enough insulin.
- Some people may use diabetes tablets (like metformin), but insulin is more common.
- Regular blood sugar checks are important to help keep levels steady.
Supporting Digestion
- If your pancreas doesn’t make enough enzymes, you may need pancreatic enzyme replacement therapy (PERT) (medication such as Creon).
- These enzymes help your body digest food properly and absorb nutrients.
Healthy Lifestyle
- Eating a balanced diet and keeping active can support your overall health.
- A dietitian may be part of your care team to help with meal planning.
Emotional & Practical Support
- Living with type 3c diabetes can be tough. It’s normal to feel frustrated or overwhelmed.
- Talking to your healthcare team, a counsellor, or joining a support group can make a big difference.
If you notice any of these symptoms, or have any concerns, then you should speak to your GP.
Contact your GP or health care team if:
- Your blood sugars are persistently high or difficult to control.
- You experience ongoing or worsening abdominal pain.
- You have unexplained weight loss, poor appetite, or signs of malnutrition.
- Your stools become pale, oily, or difficult to flush (signs of poor digestion).
Seek urgent medical help (call 999 or go to A&E) if you:
- Have severe or sudden abdominal pain.
- Feel very unwell, dehydrated, or confused.
- Have symptoms of low blood sugar that don’t improve after treatment (such as shakiness, sweating, or dizziness).
