Mallory-Weiss syndrome is a tear in the mucous membrane located where the esophagus meets the stomach, an area known as the gastroesophageal junction. This injury is typically caused by a sudden, sharp increase in pressure within the esophagus, leading to symptoms like bloody vomit, chest pain, or dark, foul-smelling stools.
These tears, often called Mallory-Weiss lacerations, most frequently occur during bouts of forceful or frequent vomiting associated with conditions like bulimia or severe morning sickness. They can also be triggered by intense coughing fits or persistent hiccups that put sudden strain on the abdominal area.
Treatment is managed by a gastroenterologist or a general practitioner who focuses on stopping any bleeding and stabilizing the patient. Many cases require a brief hospital stay to provide professional monitoring and prevent serious medical complications.
Main symptoms
The primary symptoms of Mallory-Weiss syndrome include:
-
Vomiting bright red blood;
-
Vomiting material that looks like dark coffee grounds;
-
Vomit containing mucus and streaks of blood;
-
Very dark, tarry, or foul-smelling stools;
-
Extreme fatigue;
-
Abdominal pain;
-
Chest pain;
-
Pain in the upper stomach area;
-
Nausea;
-
Dizziness;
-
Excessive tiredness.
If you notice symptoms of Mallory-Weiss syndrome, you should consult a gastroenterologist for testing. Since these signs are similar to other gastric issues like ulcers or gastritis, a professional diagnosis is necessary to ensure you receive the correct treatment.
Furthermore, some patients may experience a rapid heartbeat, low blood pressure, paleness, or fainting. These are signs of severe bleeding that could lead to hypovolemic shock, a life-threatening emergency that requires immediate medical intervention.
Confirming a diagnosis
A gastroenterologist diagnoses Mallory-Weiss syndrome by reviewing your medical history, performing a physical exam, and ordering blood work. Standard tests include a complete blood count (CBC), platelet count, and checks for blood clotting factors.
To confirm the diagnosis, doctors typically perform an upper endoscopy. This procedure allows them to look inside the esophagus, stomach, and duodenum to locate the tear and rule out other causes of bleeding, such as gastric ulcers or esophageal varices.
During an endoscopy, the physician can also provide immediate treatment for simple esophageal bleeding.
Additionally, the doctor may request kidney function tests, such as blood urea nitrogen (BUN) and creatinine, to rule out renal failure. They may also order cardiac enzyme tests and an electrocardiogram (EKG) to rule out heart issues or a heart attack, as these conditions can sometimes mimic the symptoms of Mallory-Weiss syndrome.
Possible causes
Mallory-Weiss syndrome can result from any condition that causes a sudden spike in esophageal pressure. The most common causes include:
-
Bulimia nervosa;
-
Hyperemesis gravidarum (severe pregnancy-related vomiting);
-
Cyclic vomiting syndrome;
-
Gastroesophageal reflux disease (GERD);
-
Portal hypertension;
-
Severe or deep coughing;
-
Persistent hiccups;
-
Intense snoring;
-
Chronic alcoholism;
-
Severe trauma or a hard blow to the chest or abdomen;
-
Heavy physical exertion;
-
Esophageal varices;
-
Gastritis;
-
Esophagitis;
-
Seizures;
-
Cardiopulmonary resuscitation (CPR);
-
Invasive medical procedures, such as an upper endoscopy or transesophageal echocardiography;
-
Complications from chemotherapy.
Mallory-Weiss syndrome may also be linked to a hiatal hernia, which occurs when a portion of the stomach pushes through the small opening in the diaphragm called the hiatus.
While there is some debate regarding whether a hiatal hernia directly causes these tears, researchers continue to study the potential connection between the two conditions.
Treatment options
Treatment for a Mallory-Weiss tear is overseen by a gastroenterologist and usually begins with hospitalization to stop any active bleeding and stabilize the patient.
During your stay, you may receive intravenous (IV) fluids or blood transfusions. These measures help compensate for blood loss and prevent the onset of hypovolemic shock.
Once the patient is stable, the doctor will use an endoscopy to see if the tear is still bleeding. Depending on what is found, treatment proceeds in one of two ways:
-
Active bleeding: The doctor uses specialized tools through the endoscope to close damaged blood vessels and stop the hemorrhage;
-
No active bleeding: The gastroenterologist may prescribe medications, such as omeprazole or cimetidine, to protect the injured area and promote healing.
Surgery for Mallory-Weiss syndrome is reserved for the most severe cases where endoscopic interventions cannot stop the bleeding. Following treatment, your doctor may schedule follow-up appointments or additional endoscopies to ensure the tear is healing properly.
