Pancreatitis Explained: Experts Share Its Causes, Symptoms, and Treatment

Pancreatitis is the swelling or inflammation of the pancreas gland. This may happen due to several reasons and can be either sudden (acute) or terminal (chronic). If you are wondering what the causes behind this condition are, and how to treat or manage it, we will answer all these and more for you today. 

To understand it better, the editorial team of OnlyMyHealth reached out to Dr Anupama NK, Senior Consultant - Medical Gastroenterology, Aster CMI Hospital, Bangalore and Dr Aseem Watts, Consultant Gastroenterology, Fortis Escorts Hospital, Amritsar.

What Causes Pancreatitis?

Befoe we delve deeper into pancreatitis, let us describe what this condition actually is. According to the National Institutes of Health (NIH), pancreatitis is inflammation of the pancreas. The Cleveland Clinic adds that this inflammation causes swelling and pain, which may feel like stomach pain that spreads to your back. The pancreas is a gland in your abdomen, located between your stomach and your spine.

Dr Anupama explains, “Pancreatitis can happen due to several causes, with the most common being gallstones and heavy alcohol use. Gallstones can block the pancreatic duct and cause inflammation. Drinking too much alcohol over time can damage the pancreas. Other causes include high triglyceride levels in the blood, certain medicines, infections, and abdominal injury. In some cases, it may be due to genetic factors or autoimmune conditions where the body attacks its own pancreas. Smoking also increases the risk. Sometimes, the exact cause is not known. Identifying the cause is important to prevent future attacks and manage the condition properly.”

Adding to this, Dr Watts shares, “Pancreatitis usually develops when digestive enzymes start attacking the pancreas itself instead of breaking down food, a process often triggered by underlying factors. The two most common causes are gallstones and excessive alcohol consumption. Sometimes, despite thorough investigation, no clear cause is identified; this case is termed idiopathic pancreatitis. What’s important to remember is that many of these triggers are preventable or manageable, and addressing them early can significantly reduce the risk of recurrent or chronic disease.”

According to a 2017 study, published in the International Surgery Journal, the common risk factors for acute pancreatitis in 104 hospitalised patients. The findings stated that women were more frequently affected by acute pancreatitis, accounting for 65% of the total cases. It further revealed that gallstones were the most common cause of acute pancreatitis overall, and they triggered the majority of cases in women. On the other hand, alcohol consumption was the leading cause of acute pancreatitis among men, noted the study. 

What Are The Types Of Pancreatitis?

Pancreatitis has four main types. Dr Anupama lists them for us:

• Acute pancreatitis: This happens suddenly and lasts for a short time. It can range from mild discomfort to a serious condition, needing hospital care.
• Chronic pancreatitis: It is a long-term condition in which the pancreas becomes permanently damaged, often due to repeated inflammation.
• Hereditary pancreatitis: This is a less common type of pancreatitis, and is often inherited.
• Autoimmune pancreatitis: There is also autoimmune pancreatitis, where the body’s immune system attacks the pancreas. 

“Understanding the type is crucial, because while acute pancreatitis may resolve completely, chronic pancreatitis needs long-term management and lifestyle changes to prevent complications and preserve quality of life,” adds Dr Watts.

What Are The Symptoms Of Pancreatitis?

How will you identify that your seemingly ‘normal’ stomach pain is actually pancreatitis? Our experts share the tell-tale signs and symptoms to help you with this.

“The symptoms of pancreatitis can vary, but often include severe pain in the upper abdomen that may spread to the back and may get worse after eating. A person may also feel nausea, vomiting, fever, and a fast heartbeat. The abdomen can feel tender or swollen,” explains Dr Anupama.

She adds, “In some cases, people may lose appetite and feel weak or tired. In chronic pancreatitis, symptoms can include weight loss, oily or greasy stools, and difficulty in digestion. Severe cases may cause dehydration and low blood pressure. These symptoms should not be ignored, and medical help should be taken early to avoid complications.”

Are There Any Long-term Complications Of Pancreatitis? 

If you are wondering whether there are any long-term complications of pancreatitis, our experts explain this as well. Dr Watts explains, “Complications arise from pancreatitis, especially if it is not managed properly. In acute pancreatitis, the high levels of inflammation can cause fluid retention, infections, and organ failure, such as the lungs, kidneys, and heart. In some cases, some parts of the pancreas die due to a lack of blood supply, a condition called ‘Necrosis’. Chronic pancreatitis is often followed by complications, too. For instance, there is malabsorption, which leads to nutritional deficiencies and even significant weight loss.” 

The expert adds, “In addition, the pancreas might lose its function in the production of insulin, which might lead to diabetes. In some cases, cysts and pseudocysts are also formed, which might rupture and cause infections. In addition, there is a slightly increased risk of cancer in the pancreas, especially in cases of chronic pancreatitis. This shows why pancreatitis should not be taken lightly and why early diagnosis, regular check-ups, and consistent treatment play a crucial role in preventing complications.”

How To Diagnose Pancreatitis?

Early diagnosis of pancreatitis helps start proper treatment and prevents serious complications. “Pancreatitis is diagnosed using a combination of symptoms, blood tests, and imaging tests. Doctors first look for signs like severe abdominal pain, nausea, and vomiting. Blood tests are done to check levels of pancreatic enzymes such as amylase and lipase, which are usually high in pancreatitis. Imaging tests like ultrasound, CT scan, or MRI help identify swelling, blockages, or damage in the pancreas,” shares Dr Anupama. She adds, “In some cases, doctors may use endoscopic tests to get a closer view. They may also check for causes like gallstones or high triglycerides.”

Shedding more light on this, Dr Watts says, “A series of clinical and laboratory investigations are undertaken to diagnose pancreatitis. A series of questions is asked to determine the nature and site of pain. Early diagnosis is critical since it will determine the course of treatment and help prevent complications. If the patient is not improving, further investigation is done to determine the cause.”

Treatment and Management Tips For Pancreatitis

Shedding light on the treatment of pancreatitis, Dr Anupama shares that it depends on its cause and severity, but most cases need hospital care in the beginning. The expert lists the following points in this regard:

• Patients are usually given painkillers through IV drips and are advised to rest the pancreas by avoiding food for some time.
• Once symptoms improve, a light diet is started.
• If gallstones are the cause, procedures may be done to remove them.
• Infections may need antibiotics.
• In chronic pancreatitis, treatment includes enzyme supplements to help digestion and medicines to control pain.
• Lifestyle changes like stopping alcohol and smoking are very important to prevent further damage and future attacks.

A 2025 study, published in the United European Gastroenterology Journal (UEG Journal), recently treated advances for acute pancreatitis primarily focused on supportive care, such as providing early intravenous fluids, managing pain, and ensuring proper nutrition. Despite these improvements, no specific medications are available at present that can successfully stop the early progression of the disease. The study highlights that future clinical trials are the need of the hour to discover new, direct therapies and improve overall care for this condition.

When To See a Doctor

You should make an appointment with your medical professional if you experience sudden belly pain or belly pain that doesn't improve. Seek immediate medical help if your pain turns severe, so much so that you are not able to sit still or find a position that makes you more comfortable.

Conclusion

Pancreatitis is inflammation of your pancreas. Its treatment depends on its severity and the cause. With the right care and discipline, the symptoms can be controlled effectively.
