Approximately 20 percent of women and 50 percent of pregnant women have low iron levels, estimate health professionals with MedlinePlus. Iron deficiency, which is also called iron-deficiency anemia, occurs when your body doesn't have enough red blood cells because of inadequate iron levels. Seek additional care from your medical provider if you develop any of the symptoms associated with iron deficiency in women to ensure you receive appropriate care.
Fatigue and Weakness
Low iron levels reduce the number of red blood cells your body has available to transport oxygen to your organs, tissues and cells. Without oxygen, your cells cannot produce the energy your body needs to function normally. Consequently, you may develop symptoms of excessive fatigue or unusual weakness if you are iron deficiency. These symptoms may develop slowly over time and may affect your ability to concentrate or remain attentive or active throughout the day.
Headache, Dizziness or Breathing Difficulties
An iron deficiency may prevent your brain from receiving the oxygen it needs to keep your neurons functioning properly. If you brain doesn't receive enough blood or oxygen, you may experience symptoms of throbbing headache pain, lightheadedness or dizziness, MayoClinic.com warns. Sensations of dizziness may leave you feeling confused or disoriented. You may also notice that you experience shortness of breath during your normal physical activities such as walking up a flight of stairs. Consult your physician if these symptoms of iron-deficiency anemia do not subside or become severe.
Brittle Nails or Cold Extremities
When blood and oxygen supplies are limited, your body decreases the amount of blood that flows to your hands and feet to ensure that your vital organs receive enough blood. Consequently, you may notice that your hands or feet feel unusually cold all the time or appear pale in color. Your nails may also become brittle or discolored and may break easily. These symptoms of iron deficiency typically subside once your iron levels return to normal.
Elevated Heart Rate
Your heart may begin to beat faster if you don't have enough iron in your body. Your heart rate increases in an effort to supply your body with more oxygen and blood. Additional symptoms, such as chest pain, may accompany heart rate changes. Contact your doctor immediately if you experience severe or sudden chest discomfort or heart rate irregularities, as these symptoms of an iron deficiency may also be signs of a potentially fatal heart attack.
