Pancreatitis is a condition where the pancreas becomes inflamed, causing sudden or long-lasting pain and serious digestive problems. The pancreas is a vital organ that helps your body digest food and control blood sugar. In Canada, pancreatitis accounts for a significant number of emergency room visits every year. Understanding the causes, symptoms, and treatment options can help you act quickly and protect your health.
What Is Pancreatitis?
The pancreas sits behind your stomach, in front of your spine. It works as two systems in one organ. First, it produces powerful digestive enzymes that flow into your small intestine to break down carbohydrates, proteins, and fats. Second, it releases hormones like insulin and glucagon directly into your bloodstream to control blood sugar levels.
In a healthy pancreas, digestive enzymes only become active once they reach the small intestine. However, when pancreatitis develops, these enzymes activate too early — while still inside the pancreas. As a result, the pancreas begins to digest itself. This process causes inflammation, pain, and in serious cases, permanent tissue damage.
There are two main forms of this condition: acute pancreatitis and chronic pancreatitis. Each has different causes, symptoms, and treatment approaches. You can learn more about how the pancreas works from Mayo Clinic’s overview of pancreatitis.
Acute Pancreatitis: Sudden and Serious
Acute pancreatitis comes on suddenly and can range from mild discomfort to a life-threatening emergency. It is one of the most common reasons people visit emergency departments for abdominal issues. The good news is that more than 80% of patients recover fully with prompt medical treatment.
Common Causes of Acute Pancreatitis
The two leading causes of acute pancreatitis are gallstones and heavy alcohol use. Gallstones can block the duct that drains the pancreas, causing enzymes to back up and activate prematurely. Excessive alcohol consumption irritates pancreatic tissue directly.
Other causes include certain medications, viral infections, physical injury to the abdomen, and metabolic conditions such as high triglycerides (fats in the blood) or poorly controlled diabetes. In some cases, pancreatitis can occur after certain medical procedures near the pancreas. In about 10 to 15% of cases, doctors cannot find a clear cause.
Symptoms of Acute Pancreatitis
Acute pancreatitis symptoms appear quickly and can be intense. The most common symptom is severe upper abdominal pain that often radiates to the back and left shoulder. Many people describe it as a “band-like” pain that wraps around the torso. Eating — especially fatty foods — tends to make the pain worse.
Other symptoms include:
Nausea and vomiting
Swollen or tender abdomen
Diarrhoea or stopped bowel movements
Fever and rapid heart rate
Cold sweats and general weakness
In severe cases, acute pancreatitis can cause internal bleeding, large areas of dead tissue (necrosis), and bacterial infection. These complications can lead to multi-organ failure, where the kidneys, lungs, and brain all become affected. This is a medical emergency requiring immediate hospital care.
Chronic Pancreatitis: Long-Term Damage
Chronic pancreatitis develops slowly over time, often following one or more episodes of acute pancreatitis. Unlike the acute form, chronic pancreatitis causes ongoing inflammation that gradually scars the pancreas through a process called fibrosis. Over time, this scarring destroys the pancreas’s ability to function properly.
Common Causes of Chronic Pancreatitis
In more than 70% of cases, chronic pancreatitis is linked to long-term heavy alcohol use. Other causes include certain metabolic disorders, autoimmune conditions, and in rare cases, an inherited genetic condition. Chronic pancreatitis is less common than acute pancreatitis, but its effects can be far more disabling.
Symptoms of Chronic Pancreatitis
Chronic pancreatitis can be silent for months or even years. Some people have no symptoms at all between flare-ups. However, when symptoms do appear, they can seriously affect quality of life.
The most common symptom is persistent upper abdominal pain, similar in location to acute pancreatitis. The pain can be constant and does not always respond well to standard pain relievers. Furthermore, as the pancreas loses its ability to produce digestive enzymes, patients develop malabsorption — the body can no longer absorb nutrients properly from food.
Signs of malabsorption include:
Significant unintended weight loss
Foul-smelling, greasy stools (called steatorrhoea) — caused by undigested fat passing through the bowel
Bloating and digestive discomfort after meals
Difficulty eating high-fat or high-protein foods
As chronic pancreatitis progresses, it can also damage the insulin-producing cells of the pancreas. This leads to diabetes, because the body can no longer regulate blood sugar properly. According to Health Canada, managing both digestive health and blood sugar is essential for Canadians living with chronic pancreatic conditions.
Diagnosing Pancreatitis in Canada
If your doctor suspects pancreatitis, they will order a combination of blood tests and imaging studies. Blood tests look for elevated levels of pancreatic enzymes — specifically amylase and lipase. High levels of these enzymes strongly suggest pancreatitis.
Imaging tests such as an abdominal ultrasound, CT scan, or MRI help doctors see the size and condition of the pancreas. These tests can also detect gallstones or areas of damaged tissue. In Canada, these tests are generally covered under your provincial health plan when ordered by a physician.
Your family doctor or emergency physician will guide the diagnostic process. In some situations, you may be referred to a gastroenterologist — a specialist in digestive diseases — for further evaluation and long-term management.
Treatment Options for Pancreatitis
Treatment depends on whether you have acute or chronic pancreatitis and how severe your condition is.
Treating Acute Pancreatitis
Most cases of acute pancreatitis require a hospital stay. Treatment focuses on resting the pancreas and supporting the body while it heals. This usually means fasting (not eating by mouth) for a period of time, receiving fluids and nutrition through an IV, and managing pain with appropriate medications.
If gallstones caused the pancreatitis, doctors may recommend removing the gallbladder once the inflammation settles. If there is an infection or dead tissue in the pancreas, surgery or a drainage procedure may be necessary. Most patients recover fully within a week or two with proper care.
Treating Chronic Pancreatitis
Chronic pancreatitis requires long-term management. The most important step is stopping alcohol use completely. This alone can significantly slow the progression of the disease. Your doctor may also recommend quitting smoking, as smoking worsens pancreatic inflammation.
Additional treatments include:
Pancreatic enzyme replacement therapy (PERT) — prescription enzyme supplements taken with meals to aid digestion
A low-fat diet, with smaller and more frequent meals
Pain management through medication, nerve blocks, or in some cases, surgery
Insulin therapy if diabetes develops as a complication
Nutritional support from a registered dietitian

When to See a Doctor
You should seek care immediately if you experience sudden, severe abdominal pain — especially if it spreads to your back and is accompanied by vomiting, fever, or a rapid heartbeat. Do not wait to see if it improves on its own. Go to your nearest emergency department or call 911.
For milder or ongoing digestive symptoms — such as unexplained weight loss, greasy stools, or recurring abdominal discomfort — book an appointment with your family doctor. If you do not have a family doctor, a walk-in clinic can assess your symptoms and refer you to the right specialist. Early diagnosis makes a real difference in outcomes for both acute and chronic pancreatitis.

Frequently Asked Questions About Pancreatitis
What are the first signs of pancreatitis?
The first sign of pancreatitis is usually sudden, severe pain in the upper abdomen that may radiate to the back. Nausea, vomiting, and fever often follow quickly. If you experience these symptoms, seek emergency medical care right away.
Can pancreatitis go away on its own?
Mild acute pancreatitis may improve with rest, fasting, and IV fluids in hospital, but it does require medical supervision — it will not safely resolve at home without treatment. Chronic pancreatitis does not go away on its own and needs ongoing management. Always see a doctor if you suspect pancreatitis.
What foods should I avoid if I have pancreatitis?
People with pancreatitis should avoid high-fat foods, fried foods, alcohol, and large meals, as these can trigger or worsen inflammation. A low-fat diet with small, frequent meals is generally recommended. A registered dietitian can create a personalised eating plan suited to your needs.
Is pancreatitis linked to diabetes?
Yes — chronic pancreatitis can damage the insulin-producing cells in the pancreas, leading to a form of diabetes known as pancreatogenic or type 3c diabetes. Managing pancreatitis effectively helps reduce this risk. Your doctor will monitor your blood sugar levels as part of your care plan.
How is pancreatitis diagnosed in Canada?
In Canada, pancreatitis is diagnosed using blood tests that measure pancreatic enzyme levels (amylase and lipase), along with imaging such as ultrasound or CT scan. These tests are typically covered by your provincial health plan when ordered by a doctor. Your family doctor or emergency physician will coordinate the appropriate tests.
What is the difference between acute and chronic pancreatitis?
Acute pancreatitis comes on suddenly and, with proper treatment, most people recover fully. Chronic pancreatitis develops slowly over time, causing permanent scarring and long-term loss of pancreatic function. Both forms of pancreatitis require medical attention, but chronic pancreatitis needs lifelong management.
