The Hidden Causes and Links Between GI Bleeding and Low Haemoglobin
                     The Hidden Causes and Links 
Between GI Bleeding and Low 
Haemoglobin
Introduction
Low haemoglobin, often seen as fatigue, 
weakness, or pale skin, can sometimes be 
a hidden indicator of internal blood loss 
from the gastrointestinal (GI) tract.
 Recognising this connection through 
haematology tests in Dubai helps identify 
the underlying cause and ensures timely 
treatment before complications arise.
How GI Bleeding Leads to Low 
Haemoglobin
GI bleeding can occur anywhere along the 
digestive tract—from the oesophagus to the 
rectum.
 Even small but chronic bleeding can lower 
haemoglobin levels over time, leading to anaemia.
 Low haemoglobin reduces oxygen transport, 
causing tiredness, dizziness, and shortness of 
breath.

Diagnostic 
Approach
Early diagnosis combines 
gastrointestinal testing in Dubai with advanced 
blood assessments to find both the source and its 
impact.
Tests Include:
• Blood Tests (CBC): Measure haemoglobin and 
red blood cells
• Stool Tests (FIT/FOBT): Detect hidden blood in 
stool
• Endoscopy & Colonoscopy: Visualise ulcers, 
lesions, or tumours
• Capsule Endoscopy / CT Scans: Identify small 
intestine bleeding sites
Advanced Diagnostic 
Insights
Some specialised laboratories use molecular diagnostics, 
such as exome sequencing, to detect inherited or rare 
gastrointestinal disorders linked to recurrent bleeding or 
abnormal clotting.
These advanced tests support precise treatment planning 
for chronic or unexplained anaemia.aemia.

Conclusion
GI bleeding and low haemoglobin are closely 
connected, often progressing silently.
 Through comprehensive haematology tests and 
gastrointestinal testing in Dubai, patients can identify 
the cause early, restore haemoglobin levels, and 
protect their long-term digestive health.
