Primary-care approach

Do not diagnose chronic pancreatitis or pancreatic exocrine insufficiency from bloating and flatulence alone; undertake a structured assessment for pancreatic-type pain, malabsorption, endocrine symptoms, alcohol and smoking exposure, family history, nutritional status, and alternative gastrointestinal causes.

Clarify whether there is recurrent or persistent upper abdominal pain, particularly pain consistent with chronic pancreatitis, and ask about new or progressive symptoms of exocrine or endocrine pancreatic insufficiency.

Specifically seek malabsorption features, including steatorrhoea or other changes suggesting fat malabsorption, unintentional weight loss, nutritional deficiency symptoms, and reduced functional status.

Assess alcohol intake or dependence, smoking, hypercalcaemia risk, hypertriglyceridaemia, medicines, and family history, as these may identify modifiable or inherited contributors to chronic pancreatitis.

Examine for nutritional compromise and abdominal signs, while recording weight and BMI as a baseline for longitudinal monitoring.

Initial blood tests should include liver function tests, with serum protein and albumin where malnutrition is possible.

In this man with obesity and possible fatty liver, use the liver assessment to identify biochemical evidence requiring appropriate liver-pathway assessment, while addressing cardiometabolic risk factors in parallel.

Stepwise diet and lifestyle plan

  • Alcohol: advise avoidance of alcohol if chronic pancreatitis is suspected or confirmed, and assess and manage alcohol misuse or dependency.
  • Smoking: offer smoking-cessation support if he smokes, as smoking is a modifiable chronic-pancreatitis risk factor.
  • Weight and activity: set a realistic, sustained weight-management goal using a calorie-controlled, nutritionally adequate eating pattern and progressive physical activity, tailored to his sedentary baseline and obesity; monitor weight and BMI at review.
  • For bloating and flatulence: use a symptom-and-food diary, regular meals, slower eating, and reduction of identifiable gas-producing foods or carbonated drinks as a pragmatic dietary trial, while avoiding unnecessarily restrictive diets and maintaining nutritional adequacy.
  • If chronic pancreatitis or malabsorption is confirmed: arrange dietitian assessment for nutritional support, monitor for fat-soluble vitamin deficiency and consider supplementation when indicated.
  • Pancreatic enzyme replacement therapy: use pancreatic enzyme replacement therapy regularly with meals and snacks when pancreatic exocrine insufficiency is diagnosed or clinically indicated; pancreatin preparations are indicated for pancreatic deficiency states including chronic pancreatitis. ,

Symptom treatment and monitoring if chronic pancreatitis is confirmed

For mild-to-moderate pain, use paracetamol or an NSAID first line after checking individual contraindications and interactions.

For severe pain, consider a weak opioid such as codeine, and consider amitriptyline or gabapentin where neuropathic pain is suspected, using clinical judgement.

Monitor for diabetes with HbA1c every 6 months in confirmed chronic pancreatitis, recognising that a normal HbA1c may not exclude pancreatogenic diabetes.

If diabetes is confirmed, consider specialist endocrine assessment to establish pancreatogenic diabetes and guide treatment.

Offer DXA assessment of bone density every 2 years in confirmed chronic pancreatitis.

Triggers for further investigation or referral

  • Arrange further pancreatic imaging with CT or MRI if pain is persistent, worsening, disproportionate, unexpectedly worse, changes character, or new symptoms develop.
  • These features may indicate pancreatic or extra-pancreatic complications, including pseudocyst, duodenal or bile-duct obstruction, pancreatic malignancy, or centrally sensitised pain.
  • Arrange assessment for pancreatic exocrine insufficiency when new malabsorption symptoms occur or when symptoms deteriorate.
  • Seek specialist pancreatic function testing when symptoms of pancreatic exocrine insufficiency persist despite adequate pancreatic enzyme replacement therapy, while considering alternative causes such as coeliac disease or small-bowel bacterial overgrowth.
  • Escalate for specialist gastroenterology, pancreatico-biliary surgery, pancreatic-centre, or pain-clinic assessment when symptoms are worsening or uncontrolled, with urgency determined by clinical judgement.
  • Refer to a specialist pancreatic centre for complications such as pancreatic ascites or pleural effusion.
  • Make an urgent suspected-cancer referral when pancreatic cancer is suspected, particularly where there is unexpected worsening pain or new concerning clinical change.
  • Review unusual abdominal symptoms or a change in abdominal symptoms in anyone receiving high-dose pancreatin, particularly above 10,000 units/kg/day lipase, to exclude colonic damage. ,,

Practical review point

At follow-up, document the response of bloating, flatulence, pain, bowel habit, weight, diet, alcohol and smoking status, and blood-test findings; deterioration, objective malnutrition, malabsorption, abnormal liver tests, diabetes, or evolving pain should lower the threshold for diagnostic escalation.
