What Happens If Ferritin Levels Are Too Low?

Extremely low ferritin levels indicate severe iron deficiency, which can result in iron deficiency anemia. Symptoms include extreme fatigue, weakness, dizziness, shortness of breath, and brittle nails. Long-term low ferritin can impair immune function and cognitive performance. Treating low ferritin involves increasing dietary iron, supplementation, and addressing any underlying causes like chronic blood loss.
