Always Tired at Work? The Blood Tests Behind Chronic Fatigue

"I'm just tired" is the most under-investigated complaint in Gurugram's office corridors. Long commutes and screen hours explain some of it — but a five-test panel explains most of the rest.

1. CBC — Look for Anaemia

Low haemoglobin is the single most common reversible cause of fatigue, especially in women. Add ferritin and iron studies to know whether iron stores are truly low.

2. Thyroid Profile (TSH, T3, T4)

An underactive thyroid causes tiredness, weight gain, cold intolerance and low mood — and it is very common in Indians.

3. Vitamin B12

Vegetarian diets make B12 deficiency widespread. It causes fatigue, tingling in the hands and feet, and poor concentration.

4. Vitamin D

Indoor work plus monsoon cloud cover drives levels down, producing body ache and low energy.

5. Blood Sugar and HbA1c

Both undiagnosed diabetes and post-meal sugar crashes cause afternoon exhaustion. HbA1c shows the 3-month picture in one test.

Worth Adding If Symptoms Persist

• LFT and KFT — liver and kidney contribution
• Cortisol — chronic stress patterns
• CRP and ESR — hidden inflammation or infection
