Symptoms of menorrhagia

An estimated 10% of all women in their reproductive years have chronic gynecologic problems. 

Nearly 30% of women reporting such problems spend one or more days in bed per year because of them. 


  • Menorrhagia is the most common cause of anemia in premenopausal women. 
  • According to one report, 10% of women in their reproductive years have iron deficiencies, and between 2% and 5% have iron levels low enough to cause anemia. 
  • Although poor diets play a role in many cases, the problem is compounded in women who have heavy periods. 
  • Most cases of anemia are mild. Nevertheless, even mild anemia can reduce oxygen transport in the blood, causing fatigue and a diminished physical capacity. (In fact, some studies indicate that even iron deficiency without anemia can produce a subtle but still lower capacity for exercise.) Moderate to severe iron-deficiency anemia is known to reduce endurance. 
  • Moderate to severe anemia can also cause shortness of breath, rapid heart rate, lightheadedness, headaches, ringing in the ears (tinnitus), irritability, pale skin, restless legs syndrome, and mental confusion. Heart problems can occur in prolonged and severe anemia that is not treated. Pregnant women who are anemic, particularly in the first trimester, have an increased risk for a poor pregnancy outcome.


  • Heavy bleeding is often accompanied by menstrual cramps, particularly if the bleeding is caused by uterine fibroids


  • Some conditions associated with heavy bleeding, such as ovulation abnormalities, fibroids, or endometriosis, are important contributors to infertility.
