You're scrolling through the internet because your upper abdomen feels like it’s being gnawed on by a very small, very angry animal. Maybe you’ve already seen them. Those glossy, pinkish-red circles that look like craters on the moon. If you’ve been hunting for pics of ulcers in the stomach, you aren't just looking for a biology lesson; you’re looking for a reason why you feel like garbage. It’s scary. Seeing a literal hole in a human organ—your organ—is unsettling. But honestly, most of the images you find online lack the context of what’s actually happening in the clinical room when a gastroenterologist is staring at a monitor.
Peptic ulcers aren't just "sores." They are deep erosions. Think of it like a pothole in a road that goes all the way down to the gravel.
What those pics of ulcers in the stomach are really showing you
When a doctor performs an endoscopy—technically an EGD (Esophagogastroduodenoscopy)—they slide a thin tube with a high-definition camera down your throat. The photos they take aren't just for your scrapbook. They’re looking for specific margins. A benign gastric ulcer usually looks like a punched-out, neat circle with a smooth base, often covered in a white or yellowish substance called exudate. This is basically a "scab" of protein and white blood cells trying to protect the raw tissue underneath.
But not all ulcers look the same. Some are shallow. Others are deep enough to bleed. If you see a photo where the ulcer has a black spot in the middle, that’s often "hemature" or "clotted blood." It means that thing was recently bleeding.
The color matters too. A clean, white base is generally a good sign—it means the ulcer is stable. If the edges look irregular, heaped up, or "shaggy," doctors start worrying about malignancy. It’s a harsh reality, but stomach cancer can sometimes mimic the appearance of a standard ulcer. That’s why biopsy is the gold standard. You can't just look at a picture and know for sure.
The H. pylori factor and why it matters
For decades, we blamed stress. We blamed spicy food. We told people to drink milk and "calm down." Then came Barry Marshall and Robin Warren. These guys proved that a spiral-shaped bacterium called Helicobacter pylori was actually the culprit behind most of these craters. Marshall famously drank a beaker of the bacteria to prove his point. Talk about dedication to the craft.
If your stomach looks like a war zone in those medical photos, H. pylori is likely the general leading the charge. It burrows into the mucosal lining, neutralizing stomach acid around itself to survive, which then triggers an inflammatory response that eats away at your own tissue.

Why NSAIDs are the silent saboteurs of your stomach lining
Maybe you don't have an infection. Maybe you just have bad knees or chronic headaches.
If you're popping Ibuprofen, Naproxen, or Aspirin like they're Tic-Tacs, you are effectively stripping the "grease" off your stomach walls. These drugs, known as NSAIDs (Non-Steroidal Anti-Inflammatory Drugs), inhibit COX-1 enzymes. These enzymes are responsible for producing prostaglandins that protect your stomach lining from its own acid.
Without that protective slime, the acid—which is strong enough to dissolve a nail—starts digesting you.
When you look at pics of ulcers in the stomach caused by NSAIDs, they often appear as multiple small erosions rather than one big "punched out" hole. It’s more like a shotgun blast of irritation. Doctors call this gastropathy. It’s incredibly common in older adults who have been on daily aspirin therapy for years without a "buffer" medication like a PPI (Proton Pump Inhibitor).
Understanding the "Zone of Death" in the stomach
The stomach isn't just one big bag; it has neighborhoods. Most ulcers show up in the "antrum," which is the lower part of the stomach, or the "lesser curvature." Why? Because that’s where the acid tends to pool and where the tissue is under the most mechanical stress.
If an ulcer is found in the "fundus" (the top part), doctors get suspicious. It’s an unusual neighborhood for a standard ulcer to live in.

Complications: When a photo becomes an emergency
There are three words you never want to hear after an endoscopy: Perforation, Obstruction, and Hemorrhage.
- Perforation: This is the nightmare scenario. The ulcer burns all the way through the stomach wall. Now, stomach acid and half-digested food are leaking into your sterile abdominal cavity. The pain is instantaneous and "board-like."
- Obstruction: If an ulcer is near the "pylorus" (the exit to the small intestine), the constant swelling and scarring can literally plug the hole. You eat, but the food has nowhere to go. You end up vomiting everything back up.
- Hemorrhage: This is what happens when the erosion hits a blood vessel. You might not feel pain, but you’ll see "coffee ground" vomit or black, tarry stools (melena).
I’ve seen cases where a patient felt "fine" but was strangely tired, only for an endoscopy to reveal a slow-leaking ulcer that had dropped their hemoglobin to dangerous levels. The photos from these procedures often show "active spurting," which requires the doctor to use tiny clips or a heater probe to cauterize the site right then and there.
Misconceptions about spicy food and "stress ulcers"
Let’s clear something up. Eating a ghost pepper will hurt like hell, but it won't cause an ulcer. It will just make an existing one feel like a blowtorch.
True "stress ulcers" are actually quite rare and usually only happen in people who are in the ICU with massive trauma or burns (Cushing’s or Curling’s ulcers). The daily stress of your job or your taxes isn't going to burn a hole in your stomach on its own. It might make you produce more acid, and it might make you reach for the Ibuprofen more often, but the bacteria or the meds are usually the real culprits.
Diagnosis is more than just a picture
While looking at pics of ulcers in the stomach helps you visualize the problem, the diagnosis involves a few more steps:
- The Urea Breath Test: You drink a liquid and blow into a bag. If the bacteria are there, they break down the liquid and release a specific gas.
- Stool Antigen Test: Exactly what it sounds like. Not fun, but very accurate.
- The Biopsy: During the endoscopy, the doctor snips a tiny piece of tissue. It doesn't hurt (the stomach doesn't have those kinds of pain receptors), but it's vital for checking for cancer or H. pylori under a microscope.
Actionable steps for your gut health
If you suspect you have an ulcer, or if you've been looking at these images because of your own symptoms, stop self-diagnosing with antacids. Tums are a band-aid on a bullet wound if you have an active infection.

Test, don't guess. Ask your doctor specifically for an H. pylori breath or stool test. It's non-invasive and catches the majority of cases. If you're over 50 or having "alarm symptoms" like weight loss or trouble swallowing, insist on the endoscopy. It’s a 15-minute procedure that can literally save your life.
Audit your medicine cabinet. Lay out every supplement and painkiller you take. If you see NSAIDs and you have stomach pain, talk to your doctor about switching to Acetaminophen (Tylenol), which doesn't affect the stomach lining, or adding a protective coating agent like Sucralfate.
Watch the "Triple Therapy." If you do have the bacteria, you’ll likely be put on two antibiotics and a PPI. It’s a brutal regimen that can make you feel metallic and nauseous for two weeks, but you must finish it. If you don't, the bacteria can come back stronger and more resistant.
Modify the "Big Three" Triggers. While they don't cause ulcers, alcohol, smoking, and caffeine are like pouring gasoline on a fire. Smoking, in particular, slows down the healing of the stomach lining by reducing blood flow. If you want that crater in the photo to close, you have to give the tissue the oxygen it needs to knit back together.
Ulcers are treatable. They are a physical, mechanical problem that modern medicine has mostly figured out. You don't have to live with the gnawing pain, and you certainly don't have to just wonder what's going on inside. Get the test, see the specialist, and turn that "pic of an ulcer" into a "pic of a healed stomach."
