Acute Pancreatitis: symptoms and care in Luxembourg

A pain that cuts straight through to the back

Acute pancreatitis is a sudden inflammation of the pancreas, the organ deep in the abdomen that produces digestive enzymes and insulin. Its most typical sign is intense pain in the upper abdomen, often described as a band-like pain boring straight through to the back, appearing abruptly and not easing when you change position. This kind of pain, especially with vomiting, calls for urgent care — go straight to the emergency department, or call 112 if it is very severe.

The pancreas becomes inflamed when the digestive enzymes it produces — normally inactive until they reach the intestine — start activating inside the organ itself and begin damaging it. This is a sudden event, not gradual wear: most people have never felt any pancreas discomfort before the attack.

Two main causes, and no reason for blame

In the vast majority of cases, two causes explain acute pancreatitis. The first is gallstones: a small stone formed in the gallbladder migrates and blocks the duct through which pancreatic enzymes normally flow into the intestine, triggering the inflammation. The second is heavy alcohol intake, whether a single episode or a long-standing pattern, which can directly damage pancreatic tissue.

Other, rarer causes exist — certain medications, very high blood triglycerides, an anatomical abnormality of the pancreas, or, occasionally, no clear cause found at all despite a thorough work-up — but they remain a minority. Whatever the cause turns out to be, it is never a matter of fault: it's information that helps treat the attack and prevent it happening again.

What happens in hospital

Diagnosis rests on three elements: the characteristic pain, a blood test showing raised pancreatic enzymes, and often imaging (ultrasound or CT scan) that confirms the inflammation and looks for its cause. Once diagnosed, hospital admission is almost always needed, for at least a few days.

Contrary to a common assumption — perhaps because pain this severe feels like it demands immediate surgery — treating acute pancreatitis is not, in most cases, an emergency operation. Care starts with resting the pancreas: fasting for a period, substantial intravenous fluids, and pain management. Most cases, described as mild, improve within a few days with this approach. Some more severe forms need closer monitoring, sometimes in intensive care, until the inflammation settles.

When gallstones are the cause, removal of the gallbladder is usually scheduled once the attack has passed, to prevent a repeat episode — a common and well-established procedure.

After the attack: preventing it from happening again

Once out of hospital, the main task is addressing the underlying cause. If gallstones are responsible, scheduled gallbladder removal eliminates the risk of a recurrence linked to that cause. If alcohol is the trigger, support to reduce or stop drinking changes the outlook considerably; this can be arranged with a GP or specialist addiction services, without judgement. Either way, digestive follow-up is offered to check the pancreas is recovering well and to adjust diet if needed, typically by cutting back on fat in the first weeks.

Relapses do happen, especially when the underlying cause goes untreated. That is why follow-up after a first episode matters just as much as the care given during the acute attack itself. During the weeks that follow, most people also find it helpful to avoid alcohol altogether while the pancreas heals, even if the original cause was gallstones rather than drinking — the organ simply needs a period of rest, whatever set off the attack.

An overlooked organ with two quite different jobs

The pancreas quietly leads a double life. On one side, its so-called exocrine function makes the enzymes that digest fats, proteins and sugars in the intestine. On the other, its endocrine function secretes insulin, the hormone that regulates blood sugar. Acute pancreatitis mainly affects the first of these, and most people regain normal digestion once the inflammation has settled. In rare cases, especially after repeated attacks, the hormonal function can also be affected, which is why blood sugar is monitored as part of follow-up after a severe pancreatitis episode.

In Luxembourg: emergency care, then specialist follow-up

Severe, band-like abdominal pain calls for going straight to the emergency department or calling 112 without delay — this is not something to sit out at home. Once the acute phase has passed, follow-up is organised with a gastroenterologist, who looks for the precise cause and helps prevent recurrence. Hospital care, tests and follow-up are covered by the National Health Fund under the usual reimbursement rules, detailed on the CNS website.
