Hello, Heavy menstrual periods in such a way that it results in abnormally low iron and red blood cells is surely not normal. There are many reasons that can lead to such situation. I do not know your age so if you are an adolescent or if you are reaching your menopausal age, it may occur as a result of hormonal balance likely to occur at this age. If you are of childbearing age, you may have noncancerous fibroid tumors in your uterus that can cause such situation. If you are using blood thinner medicines for any other disease, it might not let the blood clot and cause prolonged bleeding. Sometimes IUD (intrauterine devise) used for birth control causes such bleeding issues in women. If you have infection in uterus, or fallopian tubes, the bleeding does not come under control until the infection comes under control. It is difficult to give advise regarding a specific disease without examining you physically and assessing your blood hormonal levels and uterine condition without blood tests and ultrasonography (USG). So yes, it is advisable to see a gynecologist for the diagnosis and treatment of your problem. The OBGYN may examine you physically, prescribe blood tests and ultrasonography and reach a diagnosis. You might need to take medicines that control hormonal levels, medicines that accelerate formation of blood clot like tranexamic acid and other medicines specific to the disorder you might be suffering from. Controlling only iron levels will not control bleeding issues. I hope this information helps. Thank you for choosing HealthCareMagic. Take care. Best, Dr. Viraj Shah
