What are the Complications of Menorrhagia?

Menorrhagia most commonly occur due to hormonal imbalance. And hormonal imbalance is most common when menstruation starts for the first time (menerche) and around the time of menopause (perimenopause). As a result, the incidence of menorrhagia is most commonly seen among young girls who starts menstruating and in women who are approaching menopause.

Menorrhagia most commonly occurs if your menstrual cycle is anovulatory (i.e. the ovaries do not produce and release a mature egg during menstruation). In a normal menstrual cycle, ovaries release an egg and it stimulates ovaries to produce progesterone, the female hormone that keep menstrual cycles regular. If the egg is not released (as seen in anovulatory cycles), there may be insufficient production of progesterone, leading to excess menstrual bleeding or menorrhagia. This explain why menorrhagia is common at the beginning of menstruation (menarche) and around the time of stopping of menstruation permanently, i.e. menopause. Because, hormonal imbalance is common during these two extremes.

What complications can occur due to menorrhagia?

Menorrhagia lead to excess menstrual bleeding in every menstrual cycle and lead to some complications, such as,

  • Iron deficiency anemia: this is the most common type of anemia. Your blood contain less hemoglobin due to lack of iron. Low hemoglobin lead to lower capacity to carry oxygen by blood, and it leads to weakness and tiredness even after minor exertion. Low hemoglobin level in blood is due to excess blood loss during every menstrual cycle, leading to lack of iron and less synthesis of red blood cells that are responsible for carrying of oxygen to tissues. In most cases iron deficiency anemia due to menorrhagia is mild. However, in some cases, if menorrhagia remain untreated for long duration or there is some associated medical condition, anemia may be severe.
  • Severe pain: pain is a common symptom of menorrhagia along with excess menstrual bleeding. Pain during menstruation or dysmenorrhea is sometimes very severe and may need prescription pain medication and sometimes even may require surgical intervention to reduce pain.
