Gastrointestinal bleeding, also known as upper gastrointestinal bleeding, typically presents with the following symptoms: 1. **Black, tarry stools**: Blood in the gastrointestinal tract is digested, forming black, sticky stools known as melena. This is one of the most common symptoms. 2. **Vomiting blood (hematemesis)**: If the bleeding is significant, it may cause hematemesis, characterized by vomit that appears like coffee grounds or bright red blood. 3. **Stomach discomfort**: There may be pain, a feeling of fullness, or a burning sensation in the upper abdomen. 4. **Nausea and vomiting**: Even in the absence of visible blood, nausea and vomiting may occur due to the irritation caused by the bleeding. 5. **Signs of dehydration**: Symptoms such as thirst, decreased urine output, dizziness, or weakness may occur due to fluid loss from bleeding. If you experience any of these symptoms, especially black stools or vomiting blood, seek medical attention immediately. A doctor will likely perform a medical history review, physical examination, and may use diagnostic tools such as endoscopy, blood tests, and imaging studies to confirm the diagnosis.
