Gastrointestinal bleeding in the tropics: Look for the hookworm

Area of Science:

• Gastroenterology
• Infectious Diseases
• Tropical Medicine

Background:

• Hookworm infection is a known cause of iron-deficiency anemia in endemic areas.
• It is often overlooked as a cause of overt gastrointestinal bleeding.

Observation:

• Three patients presented with gastrointestinal bleeding.
• Two patients had frank hemorrhage, and one experienced hypovolemic shock.

Findings:

• Endoscopic diagnosis confirmed hookworm infestation as the cause of bleeding in all three patients.
• Hookworm infestation is a treatable cause of gastrointestinal bleeding.

Implications:

• Highlights the importance of considering hookworm infestation in the differential diagnosis of gastrointestinal bleeding in tropical countries.
• Emphasizes the need for prompt diagnosis and treatment of hookworm infections to prevent severe complications like hemorrhage and shock.
