Peptic ulcer disease (PUD) is a common gastrointestinal disorder that affects millions worldwide. It refers to open sores that develop on the inner lining of the stomach (gastric ulcer), the upper part of the small intestine (duodenal ulcer), or the lower esophagus. One of the most important tools for early recognition is understanding its symptoms—and that’s where the mnemonic FAB-TIME comes into play.
This guide breaks down the FAB-TIME mnemonic to help medical students, healthcare professionals, and curious readers understand and remember the most telling symptoms of peptic ulcer disease. From abdominal discomfort to alarming signs like hematemesis and melena, we explore each feature in depth—clinically, logically, and visually.
F – Fatigue or Feeling Full Sooner (Early Satiety)
Fatigue is a non-specific yet early signal. In peptic ulcer disease, fatigue may result from chronic blood loss leading to anemia. A bleeding ulcer, even if slow and intermittent, can silently rob the body of iron, leading to iron-deficiency anemia.
Another subtle symptom is early satiety—a sensation of feeling full shortly after starting a meal. This may be caused by delayed gastric emptying or swelling near the ulcer site that compresses the gastric cavity, leaving less room for food.
Why it matters:
Early satiety is often overlooked or misattributed to lifestyle factors. But in the context of chronic epigastric pain, it becomes a red flag for deeper pathology like gastric ulcers, especially if combined with anemia.

A – Abdominal Pain or Discomfort
This is the hallmark of peptic ulcer disease. The pain is typically burning, gnawing, or dull and occurs in the epigastric region (just below the sternum). It may follow a classic pattern—worse on an empty stomach and relieved temporarily by eating or taking antacids.
Duodenal ulcers often present with pain a few hours after meals or at night, while gastric ulcers cause discomfort shortly after eating.
Clinical insight:
Many patients self-medicate with over-the-counter antacids, delaying diagnosis. Recognizing pain patterns helps differentiate between ulcer types and guides investigation like upper GI endoscopy.

B – Belching or Bloating
Excessive belching (eructation) and a sense of abdominal bloating are common in peptic ulcer patients. These symptoms occur due to increased gastric acid, gas accumulation, or dysmotility of the upper GI tract.
Why does this happen?
Ulcers alter gastric motility and pH, which disrupt digestion and promote gas buildup. Bloating may also be a result of delayed gastric emptying or irritation of nearby tissues.
Clinical challenge:
Since belching and bloating are widespread in functional disorders like irritable bowel syndrome (IBS), peptic ulcer disease should be considered when these symptoms persist along with epigastric pain.
Relevant search keywords:
- bloating and ulcers
- belching as ulcer symptom
- constant burping and stomach pain
T – Tender Abdomen
On physical examination, the epigastric region is often tender to palpation. This tenderness results from localized inflammation around the ulcer. Though not always severe, it can be sharp or aching.
In severe or complicated ulcers—such as perforation—the abdomen may become rigid or diffusely tender, indicating peritonitis. Such cases are surgical emergencies.
Real-life scenario:
A patient presenting with sudden, intense pain and a "board-like" abdomen should be evaluated immediately for perforated ulcer with upright abdominal X-ray or CT scan.

I – Indigestion (Dyspepsia)
Perhaps the most reported symptom in outpatient settings is indigestion—a general term for discomfort after meals. It includes a combination of upper abdominal fullness, burning, nausea, and burping.
Peptic ulcers are one of the organic causes of chronic dyspepsia. It is crucial to distinguish it from functional dyspepsia, which lacks an underlying anatomical lesion.
Key diagnostic clue:
If dyspepsia occurs consistently, especially in those over 45 years or with alarm features (weight loss, vomiting, bleeding), an endoscopic evaluation is warranted.

M – Melena (Black, Tarry Stool)
Melena is a serious sign of upper GI bleeding, often from a bleeding ulcer. It refers to the passage of black, foul-smelling, tarry stools due to digested blood.
The dark color results from hemoglobin breakdown by stomach acid and enzymes as the blood travels through the GI tract. It may be associated with anemia, fatigue, or shortness of breath.
Don’t confuse it with:
Hematochezia (bright red blood per rectum) typically comes from lower GI bleeding and is rare in peptic ulcers unless the bleed is massive.

E – Emesis (Vomiting)
Vomiting is an advanced symptom in peptic ulcer disease, often reflecting complications like gastric outlet obstruction (GOO) or severe mucosal inflammation.
It may be non-bilious and projectile, especially if there’s pyloric stenosis due to chronic ulceration and scarring. In some patients, vomiting contains blood (hematemesis)—another indication of active ulcer bleeding.
What to watch for:
Persistent vomiting should never be ignored. In combination with weight loss, early satiety, and epigastric pain, it could signify malignancy or gastric outlet obstruction due to a chronic ulcer.

Mnemonic “FAB-TIME” – A Summary Table
| Letter | Symptom | Explanation |
|---|---|---|
| F | Fatigue / Fullness Early | From blood loss (anemia) or delayed gastric emptying |
| A | Abdominal Pain | Classic symptom; burning, post-meal discomfort |
| B | Belching / Bloating | Due to acid buildup and slow motility |
| T | Tender Abdomen | Local pain on palpation, worse in complications |
| I | Indigestion (Dyspepsia) | Meal-related discomfort, fullness, burning |
| M | Melena | Black stools from GI bleeding |
| E | Emesis (Vomiting) | Occurs in obstruction or severe inflammation |
Why Early Detection Matters
Peptic ulcer symptoms often start subtly and are frequently ignored until complications arise—bleeding, perforation, or obstruction. Using mnemonics like FAB-TIME helps identify patterns early and prompt appropriate investigations such as:
- Upper GI endoscopy
- H. pylori testing (urea breath test or stool antigen)
- Complete blood count (CBC) for anemia
- Fecal occult blood test
Timely diagnosis allows for effective treatment using:
- Proton Pump Inhibitors (PPIs)
- Antibiotics for H. pylori
- Lifestyle modification (avoiding NSAIDs, smoking, alcohol)
- Surgery, if complications arise
Frequently Asked Questions (FAQs)
What are the red-flag symptoms of peptic ulcer that need urgent attention?
Unexplained weight loss, vomiting blood, black stools (melena), severe pain, or fainting may indicate complications like bleeding or perforation.
How can you differentiate between gastric and duodenal ulcers?
Gastric ulcers hurt soon after eating; duodenal ulcers worsen when the stomach is empty. Endoscopy helps confirm the type.
Is bloating always due to ulcers?
No. Bloating is common and can result from many causes like diet, IBS, or lactose intolerance. When associated with pain or vomiting, ulcers should be considered.
Can ulcers heal on their own?
Mild ulcers may improve temporarily, but recurrence is common without medical treatment, especially if H. pylori is present or NSAIDs are continued.
How long does it take to treat a peptic ulcer?
With proper treatment (PPIs + antibiotics if H. pylori-positive), most ulcers heal in 4–8 weeks. Endoscopy may be repeated to confirm healing in gastric ulcers.
Conclusion
Peptic ulcers are more than just stomach pain—they’re a complex interplay of acid, infection, stress, and lifestyle. Using the FAB-TIME mnemonic makes it easier to recall and recognize critical symptoms before complications strike. Whether you're a medical student prepping for exams or someone experiencing chronic digestive issues, understanding these signs can empower early action and better outcomes.
Stay alert, don’t ignore persistent symptoms, and consult a healthcare provider when in doubt.
