Can Low Iron Cause Nausea?

Yes, low iron can cause nausea, though it's not the most common symptom. Iron deficiency anemia affects approximately 3% of men and 20% of women in the United States. When your body lacks sufficient iron, it struggles to produce enough healthy red blood cells, leading to reduced oxygen transport throughout your body. This can trigger various symptoms including fatigue, weakness, pale skin, and gastrointestinal issues like nausea. The nausea often occurs with other digestive symptoms such as loss of appetite or strange cravings for non-food items. If you're experiencing persistent nausea or other signs of iron deficiency, see your healthcare provider.
