Fact or Myth: Does Spicy Food (Mirch) Cause Stomach Ulcers?

Verdict: Myth. Mirch doesn’t make a hole in your stomach; most ulcers come from a germ called H. pylori or from regular painkiller use, though spicy food can make an ulcer you already have burn more.

“Itni mirch khao ge to maiday mein zakhm ho jayega.” Every desi family has one person who says it, usually while passing the achaar. Does spicy food cause stomach ulcers? It’s a fair question in kitchens where lal mirch goes into almost everything. Here’s where the belief came from, what doctors now know about ulcers, and the honest part that spice does play. It’s part of our Fact or Myth series.

Where the belief comes from, and why it feels true

For most of the twentieth century, doctors themselves believed it. Stress, spicy food and too much acid were the accepted causes of ulcers, and patients across Pakistan, India and the rest of the world were sent home with bland diets of milk, boiled rice, plain khichdi and very little else, sometimes for months, sometimes with a warning never to touch achaar again. Your grandmother didn’t make it up. She was repeating the best medical advice of her time.

It also feels true in the body. Eat a fiery nihari on an empty stomach and you may well feel a burn under the ribs an hour later, which is a real sensation, a real discomfort, and exactly the kind of experience that makes a cause look obvious even when it isn’t. When something hurts after mirch, blaming the mirch makes sense. Anyone would.

Then everything changed. In the 1980s, two Australian doctors, Barry Marshall and Robin Warren, showed that a spiral-shaped bacterium living in the stomach lining was behind most ulcers. Marshall famously drank a culture of it to prove the point, got a nasty stomach inflammation within days, and helped turn ulcers from a lifelong “diet disease” into an infection that doctors can usually clear. Nobel Prize, 2005.

What causes stomach ulcers, in plain words

Picture a wall. Your stomach lining is that wall, with a coat of paint. The paint is a layer of mucus that protects the wall from the strong acid inside. An ulcer is a spot where the paint wears off and the acid eats into the wall itself.

Two things strip that paint far more than anything else. The first is H. pylori, a germ that’s very common in South Asia, usually picked up in childhood through food or water, and able to live quietly for years. The second is NSAID painkillers (the ibuprofen, diclofenac, naproxen and aspirin family), especially when they’re taken often, on an empty stomach, or by older people. Our piece on painkillers and stomach burning explains that one in detail.

Smoking and heavy drinking make things worse and slow healing, and rarely, other conditions are to blame. Chilli isn’t on the list. At all. Not once. Capsaicin, the hot part of chilli, doesn’t strip the lining, and in lab work it even seems to encourage the stomach to protect itself.

Myth: eating mirch makes a zakhm in the stomach

The correction is simple. Spicy food does not cause peptic ulcers, and people who eat chilli every day don’t get more ulcers because of it. Whole countries eat very hot food daily, from Thailand to Mexico to Sindh, and when doctors look at who gets ulcers there, the pattern follows H. pylori infection and painkiller use closely, while the heat of the curry on the family table makes no real difference to the numbers.

That doesn’t mean a bland diet was useless. It helped people feel better, and it just never healed the ulcer, which is why ulcers kept coming back for decades until doctors started killing the germ.

The part that is true: spice can make symptoms worse

If you already have an ulcer, gastritis or acid reflux, chilli can make the burning feel sharper. Some people notice it with raw hari mirch; others with oily, heavy, spicy food late at night. That’s real. And personal: what sets off one person does nothing to the next.

Spice also gets blamed for symptoms that are really reflux. Different problem. Reflux means acid coming up into the food pipe, and its usual triggers are a big late dinner, lying down straight after eating, extra weight around the middle, smoking and tight clothes, so a person who swaps mirch for plain food but keeps the midnight biryani and the flat pillow often finds the burn hasn’t gone anywhere.

Did you know? Chilli heat is measured in Scoville units, and the feeling of burning is a trick of the nerves. Capsaicin switches on the same pain sensors that react to real heat, so your mouth and stomach feel “burnt” when nothing has been damaged at all.

What to do instead if your stomach burns

Use this checklist if you get a gnawing or burning pain in the upper tummy that keeps coming back.

1. Write it down for 7 days: when it hurts, what you ate, and whether food makes it better or worse.
2. List every painkiller: including the ones bought over the counter for headaches, back pain or period cramps, and any “joint” or “body pain” tablets.
3. Ask about an H. pylori test: a breath, stool or blood test. If it’s positive, your doctor decides the medicine course; don’t start or stop anything yourself.
4. Eat smaller meals: and leave 2 to 3 hours between dinner and lying down.
5. Turn the heat down during a flare: cook the mirch into the salan rather than eating it raw, and go back to your normal level once you feel better.
6. Stop smoking: it slows ulcer healing more than any food does.
