What are the symptoms and manifestations of gastrointestinal bleeding?

Gastrointestinal bleeding is a serious condition that can arise from multiple causes, manifesting as symptoms such as hematemesis, melena, abdominal pain, fatigue, dizziness, decreased blood pressure, and tachycardia. It is crucial to seek medical attention promptly and adhere to the recommended treatment measures based on individual circumstances. Details are as follows:

1. Hematemesis

Patients may vomit blood, which can be bright red or coffee-colored. Seek medical attention immediately, undergo endoscopy to determine the bleeding site, and follow medical advice for hemostatic treatment.

2. Melena

Stools appear black and tarry, which is a typical symptom of upper gastrointestinal bleeding. Seek medical attention promptly, undergo fecal occult blood testing and endoscopy to identify the cause of bleeding and receive appropriate treatment.

3. Abdominal Pain

Gastrointestinal bleeding is often accompanied by abdominal pain of varying degrees. Use analgesics such as acetaminophen tablets or ibuprofen sustained-release capsules under medical guidance, and undergo imaging examinations to locate the source of bleeding.

4. Fatigue and Dizziness

Due to excessive blood loss, patients may experience fatigue, dizziness, or even shock. Seek medical attention immediately, receive blood transfusions or intravenous fluid therapy to replenish blood volume and stabilize vital signs.

5. Decreased Blood Pressure and Tachycardia

Severe bleeding can lead to decreased blood pressure and tachycardia. Monitor vital signs, receive emergency medical treatment, and undergo surgical hemostasis if necessary.

To manage gastrointestinal bleeding promptly and effectively, it is recommended that patients seek medical attention immediately upon experiencing symptoms and adhere to the prescribed treatment measures.
