"Constant fatigue may be due to iron deficiency or thyroid dysfunction; proper differentiation requires blood tests and thyroid function analysis."
On this page:
CONSTANT FATIGUE: IRON DEFICIENCY OR THYROID PROBLEM?
| Symptom | Possible Cause | Differentiation Criteria | Solution |
| Waking up tired in the morning | Iron deficiency anemia | Pale skin, low ferritin level | Iron supplementation, should be taken with vitamin C |
| Feeling sleepy throughout the day | Decreased thyroid function (hypothyroidism) | Low TSH and free T4/T3 | Thyroid should be regulated with drugs such as levothyroxine |
| Difficulty concentrating and forgetfulness | Iron and B12 deficiency | Check MCV, B12, and ferritin levels together | Support with both B12 and iron |
| Cold sensitivity, weight gain | Metabolism slowing due to hypothyroidism | Thyroid panel should be done (TSH, fT4) | Thyroid treatment and regular follow-ups |
| Dizziness and palpitations | Low hemoglobin due to iron deficiency | Complete blood count and serum iron analysis | Regular consumption of iron-rich foods |
