🩺 Mallory–Weiss Tears — Complete Overview
📌 What is a Mallory–Weiss Tear?
A Mallory–Weiss tear is a longitudinal (lengthwise) tear in the mucosal lining at the gastroesophageal junction (where the esophagus meets the stomach).
* It is a common cause of upper gastrointestinal bleeding
* Typically occurs after sudden increases in abdominal pressure
* Most cases are self-limited, but bleeding can sometimes be significant
⸻
⚠️ Causes & Risk Factors
These tears usually result from forceful or repeated strain:
Common triggers:
* Severe vomiting or retching (most common cause)
* Excessive alcohol intake
* Forceful coughing or sneezing
* Heavy lifting or straining (e.g., constipation)
* Pregnancy (labor-related strain)
Medical risk factors:
* Use of NSAIDs (e.g., ibuprofen)
* Anticoagulants (blood thinners)
* Chronic alcohol use
* Conditions causing frequent vomiting (e.g., gastritis, infections)
⸻
🤒 Symptoms
Symptoms depend on the amount of bleeding:
Key symptom:
* Hematemesis (vomiting blood)
* Bright red blood OR
* “Coffee-ground” appearance (partially digested blood)
Other symptoms:
* Nausea and retching
* Dizziness or lightheadedness
* Weakness or fatigue
* Signs of blood loss (in severe cases)
Stool changes:
* Melena (black, tarry stools) if bleeding continues
⸻
🔍 Diagnosis
Diagnosis is based on clinical history + confirmation tests:
* Upper endoscopy (EGD) → gold standard
* Confirms the tear
* Identifies active bleeding
* Blood tests
* Hemoglobin → detect anemia
* Assess severity of blood loss
⸻
💊 Treatment
Most cases are self-limited, but treatment depends on severity:
Conservative management:
* Rest and monitoring
* IV fluids (if needed)
* Proton pump inhibitors (PPIs) to reduce acid
* Antiemetics (to control vomiting)
If bleeding persists:
* Endoscopic therapy:
* Injection therapy
* Thermal coagulation
* Hemoclips
Rare cases:
* Angiographic embolization or surgery (very uncommon)
⸻
🚨 Emergency Signs (Seek Immediate Care)
Urgent medical attention is required if:
* Vomiting blood (bright red or coffee-ground)
* Black, tarry stools (melena)
* Fainting, confusion, or severe weakness
* Rapid heartbeat or low blood pressure
* Persistent or heavy bleeding
⸻
🛡️ Prevention
You can reduce risk by:
* Avoiding excessive alcohol
* Eating small, frequent, balanced meals
* Staying well hydrated
* Avoiding straining (manage constipation, careful lifting)
* Using medications responsibly (especially NSAIDs)
* Avoiding smoking
* Managing stress and conditions causing vomiting
⸻
📈 Prognosis
* Excellent in most cases
* Tears usually heal within a few days
* Recurrence is uncommon if triggers are controlled
* Complications are rare but include significant blood loss
⸻
⚖️ Key Clinical Takeaways
* A Mallory–Weiss tear is a mechanical mucosal injury, not a chronic disease
* Most cases resolve without invasive treatment
* The main risk is acute bleeding, not long-term damage
* Early recognition prevents complications
