People who have pancreatitis already ask a lot to do. Don’t drink. Not too much fat. Don’t make the food too spicy. Giving up their morning coffee seems like one too many sacrifices for many patients. It turns out that the evidence for that particular restriction is not nearly as strong as most people think.
If you really want to know if coffee is bad for pancreatitis, the honest answer is “it depends.” And I don’t mean that in a vague, half-hearted way. The real factors at play are the type of pancreatitis a person has, how bad their condition is, what they put in their coffee, and how their digestive system reacts to caffeine. If two people have the same diagnosis, they might have very different reactions to the same morning latte.
The fact that experts have different opinions makes this even more interesting. The National Pancreas Foundation and the National Institute of Diabetes and Digestive and Kidney Diseases both say that people should not drink or eat caffeine. On the other hand, Stanford Medicine’s nutrition guidelines for people with chronic pancreatitis actually say that coffee is good for them. It’s not a mistake. Two trustworthy groups with two different points of view. Still not clear which side is more important in real life, but once you look into the biology behind each suggestion, you can see why they are made the way they are.
Dehydration is a worry that comes up a lot. Caffeine is a mild diuretic, which means it can make you lose fluids. This is a big problem for people with pancreatitis because they need to stay hydrated to help their bodies heal. But this is where it doesn’t make sense. Studies that looked at people who drink coffee every day found that coffee doesn’t really make you dehydrated. A crossover study done in 2014 found that drinking about 800 ml of coffee every day was just as good for you as drinking the same amount of water. The body changes. If the diuretic effect shows up at all, it’s usually small and short-lived in people who drink coffee often.
Researchers have found that coffee may help protect against cancer. This is the more surprising piece of the puzzle. A study from the University of Liverpool in 2006 found that caffeine can partially block the calcium channels in pancreatic cells. These channels cause the kind of cell damage that leads to pancreatitis when they are left open when oxygen levels are low. Finally, a big Kaiser Permanente cohort study that came out in 2004 looked at more than 129,000 health plan members and found that drinking coffee was weakly but significantly linked to a lower risk of alcohol-related pancreatitis. It’s not a big drop, but a real one. It’s possible that caffeine or something else in coffee changes the way an attack starts.
None of this means that people with pancreatitis should start drinking twice as much espresso. Most gastroenterologists would tell you to stay away from coffee during an active flare or in the early stages of recovery. Increasing the production of gastric acid and pancreatic enzymes can irritate an organ that is already inflamed. That advice seems to be pretty much the same everyplace. Some people with stable chronic pancreatitis may wonder if the occasional cup is really as dangerous as they’ve been made out to be. This is where things get more complicated over time.
You should also think about what goes into the coffee. It is well known that high-fat creamers, whole milk, and sweet syrups can make pancreatitis symptoms worse. A specialty drink with lots of sugar and cream is not at all like a well-made black coffee or one made with low-fat milk in terms of nutrition. What’s going on around the coffee may be much more of a problem than the coffee itself.
The best way to answer this question for yourself seems to be to start slowly, maybe with decaf coffee, and pay close attention to how your body reacts. The study doesn’t make a strong case for stable patients to stop drinking coffee completely. It also doesn’t say that it’s safe for everyone, though. To be honest, the best way to find out what’s wrong is to carefully listen to each symptom.
