Obscure GI Bleeding

Advanced Diagnostic and Treatment Solutions for Hidden Gastrointestinal Bleeding

What is Obscure GI Bleeding?

Obscure gastrointestinal (GI) bleeding refers to bleeding in the digestive tract that is not immediately apparent during initial evaluations like an upper endoscopy or colonoscopy. It is often identified through symptoms such as unexplained anemia, blood in the stool, or persistent iron deficiency. The bleeding typically originates in the small intestine, making it more challenging to detect and treat.

At Central Gastro, we specialize in diagnosing and managing obscure GI bleeding using state-of-the-art technology and personalized care to pinpoint the source of bleeding and provide effective treatment.

Symptoms of Obscure GI Bleeding

The symptoms of obscure GI bleeding can vary based on the amount and location of bleeding. Common signs include:

• Unexplained Anemia: Low red blood cell count, leading to fatigue and weakness.
• Occult Blood in Stool: Detected through stool tests, even when not visible.
• Melena: Black, tarry stools indicating upper GI bleeding.
• Hematochezia: Bright red blood in stool (less common in obscure bleeding).
• Fatigue and Weakness: Due to chronic blood loss.

If you experience these symptoms, especially without an obvious cause, a thorough evaluation is crucial.

Common Causes of Obscure GI Bleeding

Obscure GI bleeding often originates from the small intestine. Common causes include:

• Angiodysplasia: Abnormal blood vessels that are prone to bleeding.
• Small Intestinal Ulcers: Often caused by medications, infections, or Crohn’s disease.
• Small Bowel Tumors: Benign or malignant growths.
• Meckel’s Diverticulum: A congenital abnormality in the small intestine.
• Celiac Disease: Can lead to inflammation and bleeding.
• Arteriovenous Malformations (AVMs): Abnormal connections between arteries and veins.

Diagnosis of Obscure GI Bleeding

At Central Gastro, we utilize advanced tools to identify the source of obscure GI bleeding:

1. Capsule Endoscopy 

• A small, swallowable camera captures images of the small intestine, offering a detailed view to detect bleeding, ulcers, or tumors.

2. Balloon-Assisted Enteroscopy 

• An advanced endoscopic technique that allows direct visualization and treatment of the small intestine.

3. Imaging Tests

• CT Enterography or MRI Enterography: Non-invasive imaging to identify structural abnormalities or active bleeding.

4. Angiography

• Identifies active bleeding in blood vessels and enables embolization to stop bleeding.

5. Blood and Stool Tests

• Evaluate anemia, iron levels, and the presence of occult blood in the stool.

Treatment Options for Obscure GI Bleeding

Once the source of bleeding is identified, we offer tailored treatment options based on the underlying cause:

1. Endoscopic Therapy 
2. Medications
3. Interventional Radiology

Embolization: Blocking blood vessels causing active bleeding using minimally invasive techniques. (Uplink to Video)

4. Surgical Intervention

• In cases where non-invasive methods are ineffective, surgery may be required to remove tumors, ulcers, or affected portions of the small intestine.

Why Early Diagnosis and Treatment Matter

Untreated obscure GI bleeding can lead to:

• Severe Anemia: Impacting overall health and quality of life.
• Progressive Symptoms: Worsening bleeding or complications.
• Delayed Detection of Serious Conditions: Such as tumors or advanced disease.

When to Seek Treatment for Obscure GI Bleeding

If you have unexplained anemia, persistent fatigue, or blood detected in your stool, it’s essential to seek medical evaluation promptly. Early diagnosis and treatment prevent complications and ensure better outcomes.
