Fatigue, weakness? It could be more than just iron deficiency. Know the hidden risks

Unexplained fatigue? Your blood might be telling a bigger story! Here's what you need to know.

Anaemia is defined as a reduction in haemoglobin levels, with thresholds of less than 12g/dL in women and less than 13g/dL in men. Often, anaemia is a sign of an underlying disease rather than a standalone condition and the prevalence is around 17-20% in older adults in developed countries.

Anaemia is more than just low iron:

In an interview with HT Lifestyle, Dr Prashanth B, Consultant Hematology at KMC Hospital in Mangalore's Dr BR Ambedkar Circle, shared, “Most cases develop slowly, often without symptoms, but severe anemia can lead to weakness, fatigue, shortness of breath, and worsening of pre-existing conditions like heart failure, chronic kidney disease (CKD) and chronic obstructive pulmonary disease (COPD). A Complete Blood Count (CBC) with differential is the initial test to confirm anemia, followed by additional studies to identify the cause.”

The findings of the study are consistent with the National Family Health Survey-4 (2015-16), which found 22.7% of males aged 15-49 had anaemia.

He revealed, “In adults, the most common cause is blood loss, often due to ulcers in the stomach or intestines or excessive menstrual bleeding, leading to iron deficiency anemia. Malabsorption can also result in vitamin deficiency anemia. Treating these cases typically involves iron and vitamin supplementation, but further investigations, including ultrasound, endoscopy, and CT scans, are necessary to identify potential sources of blood loss.”

What anaemia could mean for you:

He concluded, “A concerning cause in adults is underlying blood cancer, necessitating specialist evaluation. If anaemia does not improve with nutritional supplementation within 1-2 months, a consultation with a haematologist is essential for further assessment.”
