You feel tired and weak
Fatigue is probably the symptom most commonly associated with iron deficiency. The reason for the exhaustion? A lack of oxygen flowing through your body. “When you have anemia, you have fewer blood cells to carry oxygen to vital organs of the body,” says Ian Tong, chief medical officer at Doctor On Demand. “This oxygen deficit is global and can cause vague symptoms like fatigue, headache, and weakness.” Learn 9 other reasons why you could be feeling fatigued.
You may be short of breath
According to the Mayo Clinic, lack of oxygen can also make someone with an iron deficiency short of breath. Studies also show that since your muscles can’t get enough oxygen to do normal activities like walking, your breathing rate increases in attempt to make up for the lack of oxygen, causing shortness of breath.
You develop restless leg syndrome
Restless leg syndrome, a nervous system disorder that creates a “pins and needles” feeling and prompts an unconscious urge to move your feet. This can disturb your sleep. It’s one of the more unusual symptoms of iron deficiency, according to Dr. Tong.
