What is it?
The pancreas is a gland behind the stomach. It makes digestive enzymes (proteins that break down fat, protein and starch) and hormones such as insulin. Pancreatitis means inflammation of the pancreas. Acute pancreatitis comes on suddenly and usually settles within days to weeks. Chronic pancreatitis is long-term inflammation and scarring that can permanently reduce enzyme and insulin production. Food matters in both: in the acute illness the question is when and how to restart eating, and in chronic disease the goal is to prevent weight loss, vitamin deficiency and pain while protecting the pancreas from further damage.
How common is it?
Acute pancreatitis is one of the most common digestive causes of hospital admission worldwide. Most attacks are mild. Roughly one in five is moderately severe or severe, and these need intensive monitoring. Chronic pancreatitis is less common but causes long-term disability, pain and malnutrition in many patients.
Why does it happen?
The two most common causes of acute pancreatitis are gallstones and alcohol. Others include very high blood fats (triglycerides), some medicines, high calcium, injury, and sometimes no cause is found. Chronic pancreatitis is most often linked to long-term alcohol use and smoking, and also to genetic factors, repeated acute attacks, blocked ducts and autoimmune disease. Food does not usually cause the first attack, except when very high triglycerides are the cause. A very fatty meal on its own is not a proven cause.
Symptoms
- Upper abdominal pain, often spreading to the back, worse after eating
- Nausea and vomiting
- Fear of eating because of pain, leading to weight loss
- Pale, greasy, foul-smelling, floating stools that are hard to flush (fat malabsorption) in chronic disease
- Bloating, gas and unplanned weight loss
- Increased thirst and passing urine often (diabetes caused by pancreatic damage)
Red flags — seek urgent medical care
Severe, constant upper abdominal pain with repeated vomiting
Possible acute pancreatitis. Go to the emergency room the same day; do not try to treat it with diet at home.
Fever, shaking chills, yellow skin or eyes, or dark urine
May signal a blocked bile duct or infection. See a doctor urgently.
Fast breathing, fast heartbeat, dizziness, or very little urine
Dehydration or severe illness. Go to the emergency room.
Vomiting blood or black stools
Bleeding in the digestive tract. Call emergency services.
Unplanned weight loss, or being unable to keep food down for more than a day or two
Needs urgent medical and dietitian review; you may need nutrition support.
How is it diagnosed?
Acute pancreatitis is diagnosed from typical pain plus a blood test (lipase or amylase more than three times the upper limit) and/or a scan. Ultrasound looks for gallstones. Chronic pancreatitis is suggested by long-term symptoms and confirmed by CT, MRI or endoscopic ultrasound. A stool test (faecal elastase) can show whether the pancreas still makes enough enzymes. Your team also checks triglycerides, calcium, blood sugar, vitamins (especially D) and bone density, and a dietitian assesses weight, muscle and intake.
What the latest science says
The 2024 American College of Gastroenterology acute pancreatitis guideline, the ESPEN pancreatitis guideline (2020) and the AGA guideline (2018) agree that in mild acute pancreatitis oral feeding can restart early, as soon as tolerated and without waiting for pain or blood tests to normalise, and that a soft low-fat diet is as safe as clear liquids. In predicted severe disease, enteral (tube) feeding is preferred to intravenous nutrition because it appears to lower infections and organ failure. For chronic pancreatitis, ESPEN (2020) and the AGA Clinical Practice Update on exocrine pancreatic insufficiency (2023) advise against routine fat restriction, recommend pancreatic enzyme replacement taken with meals, monitoring of fat-soluble vitamins, and complete alcohol and tobacco cessation. Evidence for specific foods preventing attacks is limited.
Outlook — what to expect
Most people with mild acute pancreatitis recover fully within a week or two and go home eating normally. Moderately severe and severe attacks need longer hospital care. Recurrence is common if the cause (gallstones, alcohol, triglycerides) is not treated. Chronic pancreatitis cannot be cured, but pain, weight, vitamins and blood sugar can be controlled with a team that includes a gastroenterologist and a dietitian.
Treatment
Habits & Lifestyle
Daily habits protect the pancreas and make eating easier.
- Do not drink alcohol at all if alcohol was a cause or you have chronic pancreatitis. Ask for help; brief counselling and support programmes work.
- Stop smoking and avoid all tobacco, including shisha. Smoking speeds up damage to the pancreas.
- Eat small meals every 3 to 4 hours (5 to 6 a day) rather than 2 or 3 large ones.
- Weigh yourself weekly and keep a simple record of weight, pain and stools.
- Stay physically active as tolerated; walking helps appetite, muscle and bones.
Diet
What to eat depends on whether the illness is acute or chronic. Ask your dietitian for a personal plan; the points below are general principles.
- Acute attack, mild: you do not need to fast for days. Start with water or clear fluids and move to a soft, low-fat diet as soon as nausea and pain allow, often within 24 to 48 hours. Early eating is safe and shortens hospital stay.
- Acute attack, severe: your team may give nutrition through a thin tube into the stomach or small bowel (enteral feeding), which is preferred to a drip into the vein. You will be reviewed daily.
- Chronic pancreatitis: aim for a normal, balanced diet with enough calories and protein. Muscle loss and underweight are common, so do not restrict food out of fear. Protein sources: fish, chicken, eggs, lean meat, yoghurt (laban), legumes.
- Do not follow a very low-fat diet unless told to. Fat is an important source of calories. Instead, spread fat through the day and use enzyme capsules (see Medicines). Choose healthier fats such as olive oil, nuts and fish; avoid deep-fried and very greasy foods if they trigger pain or loose stools.
- If triglycerides are very high, a stricter low-fat, low-sugar diet, weight loss and treatment of diabetes are needed; this is guided by your doctor.
- Gallstone pancreatitis: avoid prolonged fasting and rapid weight loss; surgery to remove the gallbladder is usually advised to prevent another attack.
- Oral nutrition supplement drinks can be added if food alone is not enough. Fat-soluble vitamins (A, D, E, K) and sometimes calcium, zinc or magnesium are checked and replaced when low.
- Avoid herbal remedies and high-dose supplements unless your doctor agrees.
Medications
Medicines treat pain, replace missing enzymes, and manage diabetes and other complications. Your doctor decides doses.
- Pancreatic enzyme replacement capsules are taken with the first bites of every meal and snack when the pancreas no longer makes enough enzymes. Doses are adjusted by your team to control weight and stools.
- Pain control follows a step-wise plan from your doctor; avoid taking anti-inflammatory painkillers without advice.
- Diabetes caused by pancreatic damage needs tailored treatment, often including insulin.
- Vitamin D, calcium and other supplements are given when blood tests show a low level.
- Medicines to lower triglycerides are used when diet alone is not enough.
Procedures & Surgery
Procedures treat the cause or complications. They are used selectively.
- Gallbladder removal (cholecystectomy) is advised after gallstone pancreatitis, usually during the same admission if the attack was mild.
- ERCP (a flexible camera test through the mouth) can clear a blocked bile duct or treat duct narrowing.
- Draining or removing infected dead tissue or fluid collections is done by specialist teams when needed.
- A feeding tube is placed for a period if you cannot eat enough.
- Surgery or endoscopic treatment is sometimes used for severe pain in chronic pancreatitis.
Living with the condition
- Ask for a dietitian referral, ideally one who works with pancreatic disease.
- Keep your enzyme capsules with you, including at restaurants and family gatherings.
- Have blood sugar, vitamin and bone density checks regularly in chronic pancreatitis.
- Tell family and friends that alcohol-free events and support make a real difference.
In the Saudi context
Gallstones are a leading cause in this region, so keep gallbladder symptoms in mind. Rich traditional dishes (ghee-based rice dishes, fried samboosa, creamy sweets) can be eaten in small portions with enzyme capsules if you have enzyme insufficiency. In Ramadan, people recovering from acute pancreatitis or with chronic pancreatitis on insulin or with weight loss should talk to their doctor before fasting; if you fast, split intake into suhoor, iftar and an evening snack, take enzymes with each meal, and stay well hydrated between iftar and suhoor.
Questions to ask your doctor
Save this list or print it before your appointment — doctors appreciate prepared patients.
- When can I start eating normally after an attack?
- Do I need to limit fat, or take enzyme capsules?
- What was the cause of my pancreatitis, and how do I prevent another attack?
- Do I need vitamin tests, a bone density scan or a diabetes check?
- Is it safe for me to fast in Ramadan?
