What Causes Constant Fatigue?

Fatigue is more than feeling “a bit tired.” It’s physical, emotional, and often rooted in an underlying imbalance. Here are the most common culprits:

Iron Deficiency (Anaemia) – Not enough oxygen-carrying red blood cells
Vitamin B12 or Folate Deficiency – Impacts energy, mood, and brain function
Low Vitamin D – Linked to fatigue, bone pain, and immune weakness
Underactive Thyroid (Hypothyroidism) – Slows down metabolism and energy production
Inflammation or Infection – Measured via CRP or ESR
Blood Sugar Imbalances – Unstable glucose or undiagnosed diabetes
