Quick answer: The most common causes of pancreatitis are gallstones and excessive alcohol consumption – together, they account for more than 80% of cases. In addition, certain medicines, metabolic disorders, genetic factors and autoimmune processes can also trigger the condition. Both forms of the disease – acute and chronic – require medical attention.
If you suddenly experience severe abdominal pain that radiates towards your back, accompanied by nausea and possibly a fever, there is a serious possibility that you may have pancreatitis. This condition affects many people, yet few know exactly what causes it and why a timely diagnosis is so important.
This article provides a detailed overview of the causes of pancreatitis, covering both its acute and chronic forms. You can learn about the warning signs, the most important risk factors, and when you should see a gastroenterologist. The sooner you seek treatment, the easier it is to avoid serious complications.
What is the pancreas, and why is it important?
The pancreas is an organ measuring approximately 10–12 centimetres, situated behind the stomach in the upper part of the abdominal cavity. It has a dual function:
- It produces digestive enzymes (amylase, lipase), which are involved in the breakdown of proteins, fats and carbohydrates.
- It secretes hormones: insulin and glucagon regulate blood sugar levels.
In the case of pancreatitis, these digestive enzymes are activated not in the digestive tract but within the pancreas itself. As a result, the organ begins to digest itself. This process can lead to inflammation, tissue damage and a number of serious complications.
Types of pancreatitis
Acute pancreatitis
The acute form presents with sudden, severe symptoms. In mild cases, recovery may take place within a few days; in severe cases, however, treatment in an intensive care unit may be required. There are three levels of severity:
- Mild form: The mortality rate remains below 1%, and patients recover without complications.
- Moderately severe form: Transient organ failure, but this resolves within 48 hours; the mortality rate is around 10%.
- Severe form: Prolonged organ failure lasting for more than 48 hours; the mortality rate can reach 30–50%.
Chronic pancreatitis
The chronic form is associated with irreversible tissue damage. It develops slowly and gradually, or results from repeated acute episodes. The pancreatic tissue is destroyed, and enzyme and hormone production gradually declines. It is important to note that symptoms – such as fatty, foul-smelling stools or signs of diabetes – only appear once approximately 90% of the organ’s tissue has already been destroyed.
What are the causes of acute pancreatitis?
Gallstones – the most common underlying cause
Gallstones are the leading cause of acute pancreatitis: they underlie approximately 80% of cases. Why is this? The pancreas and the gallbladder share a common duct. If a gallstone blocks this common opening, pancreatic juice builds up and enzymes are activated within the organ.
Certain factors – a high-fat diet, being overweight and high cholesterol levels – also play an indirect role in the formation of gallstones. These factors therefore also indirectly increase the risk of pancreatitis.
Alcohol consumption
Excessive alcohol consumption directly damages the cells of the pancreas and increases the production of digestive enzymes. Even a single instance of heavy alcohol consumption may be sufficient to trigger acute pancreatitis – although the condition is more common amongst regular drinkers. In the chronic form, alcohol is responsible for 70% per cent of all cases.
High triglyceride levels (hypertriglyceridaemia)
Elevated levels of triglycerides in the blood alter the composition of pancreatic juice and increase enzyme activity. This may be caused by either a genetic abnormality or a high-fat diet.
Medicines
Certain medicines – such as some antibiotics, diuretics, immunosuppressants and oestrogen-containing preparations – may increase the risk of pancreatitis. If you experience abdominal symptoms after starting a newly prescribed medicine, be sure to tell your doctor.
Other contributing factors
Although less common, the following are also among the causes of acute pancreatitis:
- Genetic mutations (e.g. PRSS1, CFTR gene): these indicate a genetic predisposition
- Autoimmune processes: the immune system attacks the pancreas’s own cells
- Infections: certain viral infections (e.g. mumps, parvovirus)
- Traumas, abdominal surgery: pancreatitis may rarely develop as a complication
- Vascular diseases: obstruction of the blood vessels supplying the pancreas
- Tumours: a tumour of the pancreas itself may also be a contributing factor
The most common causes of chronic pancreatitis
The underlying causes of the chronic form partly overlap with those of the acute form, but there are also factors that are characteristic of this form:
- Chronic alcohol consumption (case 70%): this refers to regular alcohol consumption of 80 g per day for men and 50 g per day for women, over a period of years or decades
- Smoking and toxic metabolic causes: chronic kidney failure, long-term use of certain medicines
- Bile duct obstruction: as a result of a tumour, scarring or calcification
- Autoimmune pancreatitis: an independent autoimmune disease that responds well to steroid treatment
- Genetic factors: CFTR gene mutation (cystic fibrosis)
- Idiopathic form: in 20% of the cases, the cause is not clearly established
What are the symptoms of pancreatitis?
Signs of acute pancreatitis
The symptoms of the acute form appear suddenly and intensely:
- Belt-like, severe abdominal pain: starts in the upper abdomen, around the navel, and radiates towards the back – it gets worse when lying down
- Nausea and vomiting: Vomiting does not usually bring relief
- Fever: may be a mild symptom, but is not necessarily present
- Abdominal tenderness and tightness
- Jaundice: mainly in cases caused by gallstones
- Rapid heartbeat, low blood pressure: in severe cases
Symptoms of chronic pancreatitis
The symptoms of the chronic form develop gradually, over a period of years:
- Recurring, belt-like abdominal pain that can last for days
- Fatty, foul-smelling, shiny stools (due to a lack of digestive enzymes)
- Significant, unintentional weight loss
- Bloating, feeling of fullness
- Development of diabetes (due to a reduction in insulin production)
How is pancreatitis diagnosed?
To make a diagnosis, the doctor checks for at least two of the following three criteria:
- Characteristic, belt-like abdominal pain
- Laboratory analysis: the level of amylase or lipase exceeds three times the upper limit of normal
- Imaging examination: an abdominal ultrasound, CT scan or MRI can confirm a pancreatic abnormality
It is important to note that the lipase test is more specific than the amylase test. An ultrasound scan is the first step – particularly to rule out gallstones. In cases of diagnostic uncertainty, a CT scan may also be necessary, but this should be carried out no earlier than 72 hours after the onset of symptoms, as tissue necrosis can only be reliably visualised at this stage. In cases of the chronic form, an MRCP or endoscopic ultrasound scan may also be carried out.
The treatment of pancreatitis and its complications
Treatment options
Treatment for pancreatitis always takes place in a hospital setting. The main elements of care are:
- Hydration: intravenously, in a moderate, targeted manner (Ringer’s lactate solution, 3000–4500 ml)
- Feeding: prolonged starvation is harmful – early feeding, either by mouth or via a feeding tube, is recommended
- Pain relief: stronger painkillers may also be used if necessary
- Treating the underlying cause: In the case of gallstones, endoscopic retrograde cholangiopancreatography (ERCP) may be considered if cholangitis is also present
- Antibiotic: justified only in cases of confirmed infectious necrosis; should not be used as a matter of routine
Possible complications
In untreated or severe cases, serious complications may arise:
- Kidney failure, breathing difficulties
- Fluid accumulation around the pancreas, tissue death (necrosis)
- Abscess formation, sepsis
- Bleeding within the pancreas or in the surrounding blood vessels
- Late complications: diabetes (which may not develop until 20–30 years later), the development of chronic pancreatitis
How can pancreatitis be prevented?
The good news is that the causes of pancreatitis include a number of lifestyle factors that can be influenced by conscious choices.
- Reducing or giving up alcohol: this is one of the most effective preventative measures
- A healthy, low-fat diet: reduces the risk of gallstones
- Weight management: obesity is a direct risk factor
- Stopping smoking: in itself reduces the likelihood of the chronic form
- Timely treatment of gallstones: if you have gallstones, consult your doctor as soon as possible
- Taking medication under supervision: never take risky active ingredients without medical advice

What you really need to know about pancreatitis
The causes of pancreatitis can vary widely – ranging from gallstones and alcohol to genetic factors, medication and autoimmune processes. The acute form is characterised by sudden, severe symptoms and requires immediate hospital treatment. The chronic form develops slowly, leading to irreversible tissue damage.
Timely diagnosis and treatment have a significant impact on a patient’s quality of life. If you have any persistent abdominal symptoms, do not delay seeing a specialist – early detection can truly be life-saving.
Frequently asked questions about pancreatitis
What are the most common causes of pancreatitis?
By far the most common causes of pancreatitis are gallstones (80% of acute cases) and excessive alcohol consumption (70% of chronic cases). In addition, high triglyceride levels, certain medicines, genetic factors and autoimmune processes can also trigger the condition.
How can pancreatitis be distinguished from other abdominal conditions?
A typical symptom of pancreatitis is a band-like pain in the upper abdomen, which radiates into the back and worsens when lying down. The diagnosis is confirmed by a combination of laboratory tests (amylase, lipase) and imaging techniques (abdominal ultrasound, CT scan).
Can chronic pancreatitis be cured?
The chronic form is associated with irreversible tissue damage; therefore, a complete cure is not possible. The aim of treatment is to address the underlying cause (e.g. abstinence), relieve pain, provide digestive enzyme replacement and manage diabetes. With an appropriate lifestyle and medical supervision, quality of life can be significantly improved.
Can pancreatitis be prevented through diet?
To some extent, yes. A low-fat, balanced diet reduces the risk of gallstones, thereby indirectly preventing pancreatitis caused by gallstones. Giving up alcohol is also an effective preventive measure.
When should you see a doctor straight away?
You should seek immediate medical attention if you experience a sudden, severe abdominal pain – particularly if it is accompanied by nausea, vomiting, a fever or jaundice. Pancreatitis always requires hospital treatment; it cannot be treated at home.
What tests does a gastroenterologist carry out in the case of pancreatic symptoms?
During a gastroenterology consultation at Endomedix, the specialist takes a detailed medical history, assesses the symptoms and, if necessary, recommends laboratory tests, an abdominal ultrasound or other imaging procedures (CT, MRI). Where necessary, endoscopic examinations at Endomedix are carried out exclusively under general anaesthesia, not under sedation, thereby ensuring that the procedure is completely pain-free.
