The Acute pancreatitis and the chronic pancreatitis they are two forms of inflammation of the pancreas that share similar symptoms, but whose progression, consequences and medical approach are entirely different. Recognising these differences is essential to understanding the severity of the problem, seeking medical attention in time and preventing pancreatic damage from advancing.
The pancreas it is a key organ located behind the stomach that plays two essential functions: it produces enzymes that help to digest food and hormones, such as insulin, which are involved in the control of blood glucose. When it becomes inflamed, both functions can be compromised.
What is pancreatitis?
The pancreatitis it is an inflammation of the pancreas that occurs when digestive enzymes are activated before reaching the intestine and begin to damage the pancreatic tissue itself.
Depending on its duration and the impact on the organ, it is mainly classified into:
- Acute pancreatitis, which appears suddenly.
- Chronic pancreatitis, which continues or progresses for years.
- Recurrent episodes of acute pancreatitis, which can favour the development of permanent damage.
Although acute pancreatitis can resolve completely, the chronic pancreatitis causes progressive and irreversible damage to the pancreas.
What is acute pancreatitis?
The Acute pancreatitis it is a sudden inflammation of the pancreas. In some patients it occurs mildly and improves within a few days with appropriate treatment; however, it can also evolve into a severe condition and lead to significant complications.
Generally, the patient experiences a severe pain that starts quickly and requires prompt medical or hospital assessment.
Symptoms of acute pancreatitis
The most frequent signs are:
- Severe pain in the upper abdomen.
- Radiating pain towards the back.
- Nausea and vomiting.
- Abdominal tenderness or bloating.
- Fever.
- Increased heart rate.
- General malaise.
Clinical note: The intensity of the symptoms does not always reflect the severity of the episode on its own. For this reason, it is necessary to carry out blood tests and imaging tests to assess the actual condition of the pancreas and detect potential complications in good time.
Main causes
Among the most common causes of Acute pancreatitis they are located:
- Gallstones, which can temporarily block the flow of pancreatic secretions.
- High alcohol consumption.
- Very high triglyceride levels.
- Certain medications.
- High blood calcium.
- Injuries, surgical interventions or endoscopic procedures.
- Anatomical, genetic or autoimmune abnormalities.
In some cases, despite an exhaustive investigation, it is not possible to identify a specific cause; this is known as idiopathic pancreatitis.
What is chronic pancreatitis?
The chronic pancreatitis it is a long-term disease in which the pancreas develops scarring, fibrosis and permanent structural changes.
Over time, the organ gradually loses its ability to produce sufficient digestive enzymes and hormones. Therefore, this condition not only causes persistent pain, but also directly affects the nutrition and to blood sugar control. It sometimes appears after several acute episodes, although it can also develop without apparent antecedents.
Symptoms of chronic pancreatitis
The symptoms vary throughout the course of the disease and include:
- Persistent or recurring pain in the upper abdomen.
- Worsening discomfort after eating.
- Unintentional weight loss.
- Diarrhoea.
- Fatty stools, bulky or foul-smelling (steatorrhoea).
- Indigestion.
- Vitamin deficiency and essential nutrients.
- Onset of diabetes.
Important: In advanced stages of the disease, the pain may decrease because the pancreas has lost a large part of its function. This does not mean that the clinical condition has improved, but rather that the organ is severely deteriorated.
Causes and related factors
The chronic pancreatitis tends to be associated with:
- sustained alcohol consumption.
- Smoking.
- Repeated episodes of acute pancreatitis.
- Genetic alterations.
- Autoimmune diseases.
- Obstructions of the pancreatic ducts.
- Very high triglycerides and other metabolic alterations.
Key differences between acute and chronic pancreatitis
| Feature | Acute pancreatitis | Chronic pancreatitis |
| Duration and onset | Sudden and abrupt; it usually disappears when the cause is controlled. | Prolonged over time; it produces progressive deterioration. |
| Pancreatic damage | It can heal without leaving permanent lesions (in mild cases). | It causes irreversible structural and functional changes. |
| Digestive consequences | Severe symptoms during the episode, with no initial lasting alteration. | Risk of exocrine pancreatic insufficiency, malabsorption and diabetes. |
How are they diagnosed?
The diagnosis requires combining a detailed medical record, physical examination and various complementary tests. The specialist may request:
- Blood test, including the measurement of lipase and other pancreatic enzymes.
- Abdominal ultrasound.
- Computed tomography (CT) scan.
- MRI and MRCP.
- Endoscopic ultrasound.
- Pancreatic function tests and metabolic, genetic or autoimmune studies when indicated.
It is not enough to confirm that inflammation exists; it is essential to investigate its origin, rule out complications and assess how much functional capacity the pancreas retains.
Treatment of acute and chronic pancreatitis
Therapeutic management is personalised according to the type of pancreatitis, its underlying cause and its degree of severity.
- In acute pancreatitis, hospital admission is usually required to control pain, administer intravenous hydration, monitor progress and treat complications. If stones or other obstructions are present, endoscopic or surgical techniques may be used.
- In chronic pancreatitis, the approach focuses on:
- Effective control of the pain.
- Supplementation with pancreatic enzymes with meals.
- The nutritional adaptation and the management of diabetes.
- The absolute neglect of alcohol and tobacco.
- Endoscopic or surgical treatments in selected cases.
When should a doctor be consulted?
It must be searched urgent medical attention in the event of sudden and severe abdominal pain, particularly if accompanied by persistent vomiting, fever, difficulty breathing or the inability to find a position that relieves the discomfort.
It is also highly advisable to consult a specialist if you experience repeated episodes of abdominal pain, unexplained weight loss, chronic diarrhoea, fatty stools, or a previous history of pancreatic problems.
Conclusion
Although the acute and chronic pancreatitis affect the same organ, their prognosis and approach are very different. Identifying the cause, assessing pancreatic function in good time and maintaining regular medical supervision are key to preventing further episodes, relieving symptoms and safeguarding your quality of life.
If you have suffered an episode of pancreatitis, experience recurrent abdominal pain or need a specialist medical assessment of your case, we invite you to request an appointment with the GASTEA Digestive Health team. An individualised assessment is the first step to establishing the precise diagnosis and the most suitable treatment for you.
