Heavy Menstrual Bleeding: Symptoms and Treatment. Heavy menstrual bleeding (called menorrhagia by health care professionals) is defined as soaking a pad and/or tampon every hour or less during each menstrual cycle. For many women, heavy menstrual bleeding is a huge obstacle to their lifestyles.
What Is Very Light Period? Despite menstrual cycles vary from person to person, a normal period among women is approximately once in every 28 days. Typically, each period lasts from 4 to 7 days. During menstruation, the amount of lost blood ranges from 50 to 150 ml. Consequently, less than 50 milliliters may be considered a very light period. So, light periods are menstrual flows with unusually light occurance or rather short duration of blood loss. Light periods are not just the same as âamenorrheaâ, or complete absence of menstrual periods.
