From the Guidelines
When evaluating a patient with a gastrointestinal (GI) bleed, it is crucial to ask about the color and volume of blood, timing and duration of bleeding episodes, and associated symptoms to guide immediate management decisions and determine potential causes, as recommended by the most recent guidelines 1. To characterize the bleeding and identify potential causes, important history questions should include:
- Color and volume of blood (bright red, maroon, or black/tarry stools)
- Timing and duration of bleeding episodes
- Associated symptoms like abdominal pain, dizziness, or syncope
- Medication use, particularly NSAIDs, anticoagulants (warfarin, DOACs), antiplatelets (aspirin, clopidogrel), and steroids, including doses and duration
- Alcohol consumption patterns and liver disease history
- Previous GI bleeding episodes, peptic ulcer disease, inflammatory bowel disease, diverticulosis, hemorrhoids, or GI malignancies
- Recent weight loss, changes in bowel habits, and family history of GI disorders or bleeding diatheses These questions help distinguish between upper and lower GI sources, assess severity, identify modifiable risk factors, and guide immediate management decisions, as supported by recent studies 1. The bleeding pattern often suggests the source - hematemesis or melena typically indicates upper GI bleeding, while hematochezia usually suggests lower GI sources, though massive upper GI bleeding can also present with bright red blood per rectum, as noted in the guidelines 1. Inquiring about these factors is essential to provide appropriate care and improve patient outcomes, as emphasized in the most recent update on nonvariceal upper gastrointestinal bleeding 1.

Important History Questions to Ask in Setting of GI Bleed
When evaluating a patient with gastrointestinal (GI) bleeding, it is essential to ask specific history questions to guide diagnosis and management. Some key questions to ask include:
- Medication history:
- Symptom history:
- What are the patient's symptoms, and when did they start? 5
- Has the patient experienced any previous episodes of GI bleeding?
- Medical history:
- Does the patient have any underlying medical conditions that could increase the risk of bleeding, such as liver disease or peptic ulcer disease? 2
- Has the patient had any previous surgeries or procedures that could be related to the current bleeding episode?
- Family history:
- Is there a family history of bleeding disorders or GI diseases?
These questions can help identify potential causes of the GI bleed and guide further evaluation and management, including the use of diagnostic modalities such as endoscopy 5 and imaging studies 5, as well as the management of anticoagulant and antiplatelet therapy 2, 3, 4.
