Acute Upper Gastrointestinal Bleeding Signs And Symptoms

Acute upper gastrointestinal bleeding can manifest through a variety of symptoms, each indicating a potential medical emergency. Recognizing these signs early is crucial for prompt treatment and better patient outcomes.

Common Symptoms Of Acute Upper GI Bleeding

1. Abdominal Pain and Discomfort

One of the primary indicators of acute upper gastrointestinal bleeding is abdominal pain. This pain often results from underlying conditions such as peptic ulcers, gastritis, or esophageal varices. These conditions can lead to mucosal erosion or perforation, causing both bleeding and discomfort. Additionally, patients may experience bloating and a reduced appetite.

2. Occult Blood In Stool

Even in cases of minimal bleeding, a stool test will typically reveal the presence of red blood cells. This is known as a positive fecal occult blood test and is a key diagnostic indicator of gastrointestinal bleeding.

3. Melena – Black, Tarry Stools

When there is a significant amount of bleeding in the upper digestive tract, the blood undergoes chemical changes due to gastric enzymes and bile. This reaction transforms the blood into a dark, sticky substance known as melena. The appearance of black, tarry stools is a strong sign of upper GI bleeding.

4. Hematemesis – Vomiting Blood

In severe cases, blood can accumulate in the stomach and be expelled through vomiting. This symptom, known as hematemesis, often includes the presence of digested food particles mixed with bright red or coffee-ground-like blood. It is a clear signal of substantial bleeding and requires immediate medical attention.

5. Anemia And Related Symptoms

Patients experiencing significant blood loss may develop anemia. Symptoms can include fatigue, dizziness, shortness of breath, and pallor. These signs are particularly noticeable in individuals who lose a large volume of blood rapidly.
