In short
Yes. Common pain tablets and heavy drinking can wear down the stomach lining until it bleeds, often with no warning pain first.
The risk is highest if you are older or have had an ulcer. A blood thinner, or two triggers together, adds to it.
Most of these bleeds can be prevented. Use the smallest dose for the shortest time, protect the stomach, and cut down alcohol.
This post is about stopping a bleed before it starts. Causes, scope treatment and surgery are explained on our upper GI bleeding treatment page.
Yes. Both thin the stomach’s protective layer, so acid reaches the raw tissue below and a blood vessel can open.
The stomach protects itself with a coat of mucus. Many pain tablets block the chemicals that keep this coat thick. Alcohol strips the coat directly and also makes the stomach produce more acid.
Once the lining is damaged, an ulcer or raw patches form. These may cause no pain at all. The first sign can be black stools or a vomit with blood.
Anti-inflammatory tablets, including aspirin, carry the main risk. Plain paracetamol is gentler on the stomach.
| Medicine group | Examples | Effect on the stomach | What to do |
|---|---|---|---|
| Anti-inflammatory tablets | Diclofenac, ibuprofen, naproxen, nimesulide | Thin the lining; can cause ulcers and bleeding | Use only when needed, lowest dose, short course, after food |
| Aspirin | Low-dose aspirin for the heart, or full-dose for pain | Irritates the lining and slows clotting | Never stop heart aspirin on your own; ask about stomach cover |
| Steroid tablets | Prednisolone, dexamethasone | Raise the risk, mainly when taken with an anti-inflammatory tablet | Take as advised; add stomach cover if a long course |
| Paracetamol | Plain paracetamol | Gentle on the stomach | Stay within the daily dose, as too much harms the liver |
| Skin gels and creams | Anti-inflammatory gels | Little reaches the stomach | Often a safer choice for a sore knee or back |
Taking a tablet after food helps a little, but it does not remove the risk. Injections and “slow release” forms also reach the stomach through the blood. Our post on how pain tablets harm the lining explains the damage in more detail.
Alcohol irritates the lining, raises acid, and in long-term drinkers can harm the liver, which makes bleeding harder to stop.
Vomiting after drinking can also tear the lining at the lower end of the food pipe. That tear is a known cause of bleeding.
People over 60, those with a past ulcer or bleed, and those on blood thinners or steroids need the most care.
Ask whether you need the tablet at all, use the smallest dose, protect the stomach, and cut down alcohol.
Black, sticky stools, vomiting blood or a coffee-ground liquid, feeling faint, or a sudden severe belly pain need emergency care.
Go to an emergency room. Do not wait to see if it settles, and do not take another pain tablet. The usual next step is a scope test. Our post on what happens during the scope walks you through it.
A review of your medicines, a blood count, an H. pylori test, and a scope if you have symptoms or past ulcers.
A simple blood count shows whether slow bleeding has made you anaemic. An H. pylori test, done by breath, stool or during a scope, finds the germ that makes ulcers more likely. If it is present, a short course of tablets clears it.
A scope is advised if you have had black stools, upper belly pain that returns, or an ulcer in the past. It shows the lining directly and confirms whether it has healed.
See a surgeon if you have bled before or a scope could not stop the bleed. Also go if you need long-term pain tablets after an ulcer.
A surgical gastroenterologist looks at the whole picture: the ulcer, your medicines, your liver and your heart. Dr Harsh Shah helps you decide what to keep, what to stop and what to replace. Most people need only medicines and habit changes. A few need an operation, done by laparoscopy or open surgery, if an ulcer keeps bleeding or has caused a hole. Our post on what happens after an ulcer bleed or hole explains those steps.
It is uncommon from a single dose in a healthy person. The risk rises with higher doses, longer use, older age, a past ulcer or alcohol.
It is much gentler on the stomach than anti-inflammatory tablets. Stay within the daily dose, because too much harms the liver.
Food reduces the upset stomach a little, but it does not stop the damage. The tablet still acts through the blood.
There is no fixed safe amount if you have had an ulcer or take pain tablets. Heavy or daily drinking is the main concern.
If you need anti-inflammatory tablets for weeks, or you are at higher risk, ask your doctor. Stomach cover lowers the chance of an ulcer.
No. Never stop it on your own, as this can be dangerous. Ask the doctor who prescribed it about stomach cover.
Tiredness, paleness, breathlessness and dark stools can be signs. A blood count and a scope show the cause.
See one if you have bled before or a scope could not stop the bleed. Also go if you need long-term pain tablets after an ulcer.
