Chronic pancreatitis flares—WHY do they keep happening, even when you’re doing your best to avoid them?
If you’re reading this, you probably know the drill: the gnawing pain that often escalates rapidly to unbearable pain often coupled with intracable vomiting. You know ER physicians, nurses and admission folks by first name along with the barrage of lousy hospital foods (IF you're no longer NPO).
I'm sure you would like to know why so that you may be able to "fix it," wouldn't you? Or at least obtain relief for awhile, right? Well this article may help if you're willing to make some changes.
First, let’s get something out of the way: you’re not alone. According to the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), chronic pancreatitis affects about 50 out of every 100,000 people in the US. The flares—sometimes called “acute-on-chronic” attacks—are a big part of the misery and can even become deadly. So, what’s behind them?
The Main Culprits
1. Alcohol Use (Even a Little)
Let’s start with the classic culprit. Studies show that long-term alcohol use is the leading cause of chronic pancreatitis in Western countries—accounting for up to 70% of adult cases (source). But here’s what most people don’t realize: once your pancreas is inflamed, even tiny amounts of alcohol can trigger a flare. Some people think “I only have a glass of wine at holidays,” but research confirms that once the pancreas is sensitized, there’s no “safe” amount (source).
For those of you who have followed my blog or joined my support group you already know that I am adamntly against alcohol consumption. I have even kicked people out of my group for talking about drinking alcohol yet ...
I KNOW people still drink.
How do I know? I know because some people not only suffer with CP but also cirrhosis of the liver and acohol addiction is tough to break free from. Yet in very rare instances it isn't always the fault of the patient. It may be the that severe acute pancreatitis or long term chronic pancreatitis had some hand in the cirrohosis.
Whether or not pancreatitis had a hand in your cirrhosis it's extremely wise to quit drinking unless you seriously have a death wish and love pain.
2. Gallstones and Bile Duct Issues
Gallstones are the #1 cause of acute pancreatitis. You might think gallstones are only a problem or cause for acute pancreatitis, but blockages in the bile or pancreatic ducts can cause chronic flares, too. Scar tissue from previous inflammation makes these ducts more prone to clogging—even if your gallbladder’s long gone (source).
IF you're female and your gallbladder has been removed you're at risk for SOD aka sphincter of oddi dysfunction which can and often does cause acute pancreatitis. Even if it doesn't cause AP or a flare it can make you very sick with pain nausea and vomiting. It's no fun. Guys can get this condition too it's just more prevalent in females.
3. High Triglycerides
This one flies under the radar. If your blood fats (triglycerides) are high—over 1000 mg/dL, but sometimes even lower—it can trigger acute pancreatitis. Some people are genetically prone to this, and it often goes undiagnosed. If you haven’t checked your lipids recently, it’s worth a conversation with your doctor (source).
4. Medications and Toxins
Certain medications—like some diuretics, antibiotics, and even some diabetes drugs—have been linked to pancreatitis flares. The list is long, and sometimes it’s a rare side effect, but it’s real (source). If you notice flares after starting a new medication, bring it up.
Toxins, poisons and venoms are NOT pancreas friendly and are more and more often causing pancreas inflamation. Venoms are used in certain big pharma witch brews (diabetes, weightloss, blood thinners and blood pressure meds such as Lisinopril).
In many areas venomous snakes are out year round so dress for encounters, watch where you step, sit, put your hands and sleep. Snakes like to snuggle so they often end up sleeping with unsuspecting people. The deadly banded krait in South East Asia is notorious for biting people who are sleepimg. If you don't believe me look it up.
5. Smoking
Here’s one that surprises people: smoking isn’t just bad for your lungs, it directly damages the pancreas. Multiple studies have linked cigarette smoking to more frequent and severe flares in chronic pancreatitis (source).
Smoking significantly worsens pancreatitis by accelerating disease progression, triggering inflammation, and increasing the risk of acute and chronic pancreatitis. It acts as an independent risk factor—often damaging the pancreas regardless of alcohol consumption—by inducing fibrosis, destroying acinar cells, and triggering harmful enzyme leakage.
6. Genetics
Some people just drew the short straw. Genetic mutations—most notably in the PRSS1, SPINK1, or CFTR genes—can make the pancreas extra sensitive. This is especially common in people who develop chronic pancreatitis at a younger age (source). If you have a strong family history or got sick young, ask about genetic testing.
Hereditary pancreatitis is a rare genetic disorder characterized by recurrent, early-onset acute pancreatitis that often progresses to chronic pancreatitis, causing severe abdominal pain, nausea, vomiting, and high risks of diabetes and pancreatic cancer. Primarily caused by PRSS1 gene mutations, it is inherited in an autosomal dominant pattern.
7. Diet (But Not Always How You Think)
Fatty meals can absolutely trigger a flare, but the real problem is often how your body handles fat after so much pancreatic damage.
Many people develop exocrine pancreatic insufficiency (EPI), meaning you can’t digest fat properly.
Undigested fat can irritate the gut and signal the pancreas to ramp up, even when it’s not up to the task (source).
Why Do Flares Keep Happening?
The big problem is that chronic pancreatitis is, by definition, ongoing inflammation. This is the cold hard truth ...
Once the pancreas is scarred, it’s more sensitive to triggers—think of it like a sunburn that never fully heals, only much worse.
Each flare adds more damage, making future flares even easier to set off. That’s why even “perfect” patients sometimes get flares despite doing everything right.
What Can You Do?
- No alcohol (zero means zero)
- Quit smoking
- Watch for hidden fats and trigger foods
- Manage blood sugar and triglycerides
- Review your medications with your doctor
- Consider pancreatic enzyme supplements if you have EPI
- Regular checkups to catch complications early
The Bottom Line
Chronic pancreatitis is tough, and flares can feel random or unfair. But understanding the real causes—backed by research—can help you work with your care team to cut down the frequency and maybe even break the cycle. If you’re still getting frequent attacks, don’t be afraid to push for answers: sometimes it’s just a matter of connecting the dots.
