Peptic ulcers appear as open sores or lesions in the stomach or upper small intestine lining, often showing redness, swelling, and sometimes bleeding.
Understanding the Visual Characteristics of Peptic Ulcers
Peptic ulcers are essentially open wounds that develop on the inner lining of the stomach or the duodenum, which is the first part of the small intestine. These sores result from damage caused by stomach acid and digestive enzymes. Visually, they can vary in size, shape, and severity depending on their stage and cause.
When doctors perform an endoscopy—a procedure using a flexible tube with a camera—they can directly observe these ulcers. Typically, a peptic ulcer looks like a round or oval crater with distinct edges. The base of the ulcer often appears red or inflamed due to irritation and may have a yellowish or whitish coating caused by fibrin, a protein involved in tissue repair.
In some cases, the ulcer edges are raised and thickened because of chronic inflammation. Surrounding tissue often appears swollen and reddened. If bleeding occurs, you might see fresh blood or darkened spots indicating old blood clots.
Common Locations Where Peptic Ulcers Appear
Peptic ulcers primarily occur in two regions:
- Stomach (Gastric Ulcers): These ulcers form on the stomach’s inner lining. They tend to have irregular shapes and deeper craters.
- Duodenum (Duodenal Ulcers): Found in the upper part of the small intestine, these ulcers usually have smoother edges and are more common than gastric ulcers.
Both types share similar visual traits but differ slightly in location and associated symptoms.
The Role of Inflammation and Tissue Damage in Peptic Ulcer Appearance
The hallmark of peptic ulcers is damaged mucosal tissue due to an imbalance between protective factors like mucus and aggressive factors such as acid and Helicobacter pylori bacteria. This damage manifests visually as an erosion that penetrates through the mucosa.
Inflammation leads to redness around the ulcer site. The affected area may also show edema (swelling), making it appear raised compared to surrounding tissues. Over time, repeated irritation causes thickening of ulcer margins as scar tissue forms during healing attempts.
In severe cases, ulcers can erode blood vessels beneath the lining, causing visible bleeding during endoscopy. This bleeding may appear as red spots or larger hemorrhagic areas within or near the ulcer crater.
Stages of Peptic Ulcer Development Visible Under Endoscopy
- Early Stage: Small erosions with minimal redness; mucosal surface slightly disrupted.
- Active Ulcer: Deep crater-like lesion with inflamed edges; presence of fibrinous exudate giving a white/yellow coating.
- Healing Stage: Granulation tissue covers ulcer base; edges start to flatten but remain red due to ongoing repair.
- Chronic Ulcer: Thickened margins with scar tissue formation; less inflammation visible but structural changes evident.
The Impact of Helicobacter pylori on Ulcer Appearance
Helicobacter pylori (H. pylori) infection is a leading cause of peptic ulcers worldwide. This spiral-shaped bacterium damages mucosal defenses by producing enzymes and toxins that weaken protective layers.
Visually, H. pylori-associated ulcers often present with pronounced inflammation around them. The mucosa adjacent to the ulcer site tends to be erythematous (deep red) and friable—meaning it bleeds easily when touched by instruments during examination.
Sometimes multiple small erosions accompany a main ulcer crater in H. pylori infections. This diffuse pattern distinguishes bacterial-induced ulcers from those caused mainly by nonsteroidal anti-inflammatory drugs (NSAIDs), which usually produce solitary lesions.
Differentiating NSAID-Induced Ulcers from Others Visually
NSAID-related ulcers tend to have more irregular shapes with jagged edges compared to H. pylori ulcers. They might also occur alongside other mucosal injuries like petechiae (tiny red spots) indicating widespread irritation.
The surrounding mucosa may look pale rather than bright red because NSAIDs reduce prostaglandin production—key compounds for maintaining blood flow and mucus secretion in the stomach lining.
Symptoms Linked to Visual Signs of Peptic Ulcers
While visual examination is crucial for diagnosis, many symptoms hint at an underlying peptic ulcer before imaging:
- Burning Stomach Pain: Often felt between meals or at night when acid irritates exposed tissue.
- Nausea or Vomiting: Resulting from irritation or complications such as obstruction.
- Bloating and Heartburn: Due to impaired digestion caused by damaged mucosa.
- Dark or Bloody Stools: Indicating bleeding from an ulcer site into the digestive tract.
These symptoms correlate strongly with what doctors see during endoscopy—the severity of pain often matches how inflamed or deep an ulcer appears visually.
The Importance of Endoscopic Imaging in Peptic Ulcer Diagnosis
Endoscopy remains the gold standard for identifying what peptic ulcers look like inside the body. It allows direct visualization rather than relying solely on symptom reports or indirect tests.
During endoscopy:
- The physician can pinpoint exact ulcer location.
- Tissue samples (biopsies) can be taken for testing H. pylori presence or ruling out cancerous changes.
- The extent of bleeding or complications like perforation becomes evident immediately.
Visual documentation through photographs helps track healing progress after treatment begins.
A Closer Look: Common Endoscopic Features Table
| Feature | Description | Clinical Significance |
|---|---|---|
| Circular/Elliptical Crater | A well-defined open sore with clear borders. | Confirms presence of an active ulcer needing treatment. |
| Erythematous Surrounding Mucosa | Mucosal redness around lesion due to inflammation. | Suggests ongoing irritation/infection such as H. pylori involvement. |
| Fibrin Coating (White/Yellow) | A layer covering ulcer base indicating healing attempts. | Differentiates active vs healed stages; guides therapy duration. |
| Bleeding Spots/Clots | Visible blood within or near ulcer crater during endoscopy. | Presents risk for anemia; urgent medical intervention required if severe. |
| Mucosal Edema/Swelling | Tissue around ulcer appears raised/thickened due to fluid buildup. | Indicates acute inflammation severity; affects symptom intensity. |
Treatment Effects on What Peptic Ulcers Look Like Over Time
Treatment aims either at eradicating causes like H. pylori infection or reducing acid production with medications such as proton pump inhibitors (PPIs).
As treatment progresses:
- The size of visible ulcers shrinks gradually under endoscopic observation.
- The bright redness fades as inflammation subsides; healthy pink mucosa returns around healed areas.
- The fibrinous coating disappears once re-epithelialization occurs—meaning new cells cover raw surfaces fully again.
- If scarring develops, thickened white patches may remain where deep ulcers once existed, signaling permanent structural changes but no active disease.
Monitoring these visual changes helps physicians adjust therapy length and confirm complete healing before stopping medications.
The Risk of Complications Visible Through Imaging
Ignoring peptic ulcers can lead to serious complications that alter their appearance dramatically:
- Peforation: The ulcer breaks through all stomach layers creating holes visible as deep defects surrounded by inflamed tissue on imaging;
- Bleeding: Active hemorrhage shows fresh blood pooling inside stomach lumen;
- Pyloric Stenosis: Chronic scarring narrows gastric outlet causing swelling proximal to obstruction;
- Cancerous Changes: Rarely gastric ulcers may transform into malignancies presenting irregular margins and nodular growths instead of smooth craters;
Early detection using endoscopic visuals prevents these life-threatening outcomes.
The Role of Imaging Alternatives Beyond Endoscopy
While endoscopy provides direct visualization, other techniques help assess peptic ulcers indirectly:
- Barium Swallow X-rays: Patients swallow barium contrast which coats digestive tract walls allowing X-ray images showing filling defects where ulcers exist;
- CT Scans: Useful mainly for detecting complications like perforation rather than primary diagnosis;
- Capsule Endoscopy: A pill-sized camera swallowed by patients capturing images throughout intestines but less commonly used for stomach ulcers;
Despite these options, none replace direct inspection via traditional upper GI endoscopy for detailed assessment.

Frequently Asked Questions
What Do Peptic Ulcers Look Like During Early Development?
In the early stage, peptic ulcers appear as small, red, inflamed spots on the stomach or duodenal lining. They may look like shallow erosions with some swelling around the area due to irritation from stomach acid and digestive enzymes.
How Do Peptic Ulcers Look When They Bleed?
Bleeding peptic ulcers often show fresh red blood or darkened spots indicating old clots. The ulcer crater may have irregular edges with visible hemorrhagic areas, making bleeding ulcers distinct during an endoscopic examination.
What Visual Differences Are There Between Gastric and Duodenal Peptic Ulcers?
Gastric ulcers tend to have deeper craters with irregular shapes and thicker, raised edges. Duodenal ulcers usually have smoother, rounder edges and are more common. Both types show redness and swelling but differ mainly in location and shape.
How Does Inflammation Affect the Appearance of Peptic Ulcers?
Inflammation causes redness and swelling around the ulcer site. The tissue may appear raised compared to surrounding areas due to edema. Chronic inflammation can thicken ulcer margins, giving them a raised or thickened look during endoscopy.
What Are the Typical Visual Characteristics of a Peptic Ulcer Under Endoscopy?
Under endoscopy, peptic ulcers look like round or oval craters with distinct edges. Their base is often red or inflamed, sometimes covered by a yellowish or whitish coating caused by fibrin involved in tissue repair.
The Answer Revisited – What Do Peptic Ulcers Look Like?
Peptic ulcers present visually as well-defined open sores on stomach or duodenal linings characterized by circular craters surrounded by reddened inflamed mucosa. They often feature a yellowish fibrin coating at their base indicating active damage combined with ongoing repair efforts. Inflammation causes swelling around lesion margins while bleeding spots may be evident depending on severity.
Their appearance varies depending on cause—H. pylori infections produce more diffuse redness whereas NSAID-induced lesions tend toward irregular shapes and pale surroundings due to reduced protective factors.
Endoscopic imaging remains essential for accurate identification since symptoms alone cannot reveal exact visual features reliably. Treatment success is monitored through shrinking crater size, fading redness, disappearance of fibrin layers, and eventual scar formation signaling healed tissue.
Understanding precisely what peptic ulcers look like equips patients and healthcare providers alike to recognize symptoms early, seek timely diagnosis, avoid dangerous complications, and follow effective treatment plans that restore digestive health fully over time.
