Feeling constantly tired, weak, dizzy, or short of breath can sometimes be linked to iron-deficiency anaemia. While low iron levels may often be improved with dietary changes and supplements, unexplained or persistent anaemia may require further investigation to find the underlying cause.
At Dr. Rami Hamed Center (DRHC) Dubai, our gastroenterology specialists provide a comprehensive evaluation to identify possible sources of blood loss or digestive conditions that may contribute to iron deficiency.
Iron-deficiency anaemia occurs when the body does not have enough iron to produce healthy red blood cells. Iron is essential for making haemoglobin, which carries oxygen throughout the body.
Common symptoms may include:
Iron deficiency can happen due to inadequate iron intake, increased body requirements, or blood loss. In some adults, especially when the cause is unclear, doctors may investigate the digestive system to check for hidden bleeding or other conditions.

Not everyone requires both gastroscopy and colonoscopy. The decision depends on factors such as age, symptoms, medical history, severity of anaemia, and results of initial tests.
Your gastroenterologist will recommend the most appropriate investigation to identify the cause while avoiding unnecessary procedures.
