What Is Vaginal Bleeding?

Vaginal bleeding normally happens with menstruation (a cycle that begins in females from puberty) and continues till menopause. Menstrual bleeding may vary in length, timing, or quantity. Abnormal or unexpected vaginal bleeding can also occur apart from the menstrual cycle. It can occur due to various abnormal conditions, including pregnancy complications, hormonal imbalances, infection, trauma, malignancy, and certain medications. However, the underlying causes of abnormal vaginal bleeding are treatable if promptly diagnosed and treated.

What Are the Causes of Vaginal Bleeding?

Menstrual bleeding is normal vaginal bleeding that occurs every 21 to 35 days during menstruation. Usually, the menstrual period may last for a few days or more than a week. Menstrual flow can differ from person to person and also varies in different stages of life, such as teenager and perimenopause. Abnormal vaginal bleeding can occur due to a different cause.

Some common causes of vaginal bleeding include:

  • Birth Control Medications and Devices - Using birth control methods such as birth control pills or intrauterine devices (IUD) can cause irregular bleeding.

  • Bleeding Disorders - These disorders can cause issues with normal blood clotting and can also result from an inherited condition such as von Willebrand disease, hemophilia, thrombocytopenia, vitamin K deficiency (which helps the body in making blood-clotting factors), or as a side effect of medications such as blood thinners.

  • Cancers of the Female Reproductive System - Cancer of the uterus, cervix, or fallopian tubes.

  • Ectopic Pregnancy - When the fertilized egg grows outside the uterus, typically in the fallopian tubes, serious bleeding can happen.

  • Endometrial Hyperplasia - Due to too much estrogen and a lack of progesterone, a hormonal imbalance will happen due to which the endometrium becomes thick. This is not a cancerous condition, but in some people, there is a chance of uterine cancer development.

  • Infection - Any infection in the urinary tract or pelvic cavity can cause bleeding.

  • Hypothyroidism - A decreased thyroid gland production can also interrupt normal menstrual cycles.

  • Hormonal replacement therapy.

  • Miscarriage.

  • Injury - Injury to the vagina, cervix, or uterus can occur due to sexual intercourse, during placement of an IUD contraceptive device, or any uterine surgery.

  • Placental Abruption - Detachment of the placenta from the uterus wall can happen during pregnancy which can cause severe bleeding.

  • Placenta Previa - If the placenta lies low in the uterus and covers the cervix partially or completely during pregnancy, bleeding can occur.

  • Uterine Fibroids - These are non-cancerous growths that develop from the muscle tissue of the uterus. These vary in size, growth rate, number, and location within the uterus.

  • Uterine Polyps - They are overgrowth tissues on the lining of the uterus. Uterine polyps are usually not cancerous, but some have the potential to develop into precancerous polyps.

  • Ovulation Problems - A failure or disruption of the ovaries can be due to an ovarian disorder or an issue in the brain signaling the glands that control ovulation.

When Is Vaginal Bleeding Considered Normal?

Normal vaginal bleeding, that is, menstrual bleeding, varies widely among individuals at different stages of their life. Typically, all women get a menstrual period approximately once a month (every 21 to 35 days), lasting between 3 to 7 days. Adolescence and women reaching menopause usually experience irregular period cycles. It is also common for 30 to 50-year-old women to have heavy periods. The use of contraception pills can also change the frequency and cause heavy bleeding. Sometimes facing stressful life events can skip a period entirely.

Bleeding between periods is also common, and every woman experiences it at some point during their life. However, frequent bleeding in one month or between periods of several months is not considered normal. Bleeding after having sex should always be taken into a note, and consult a doctor, regardless of the age. There are many reasons for bleeding between periods, and most cases are not serious. Light bleeding during the start of the pregnancy is also normal, but if the bleeding is heavy, it is necessary to consult a doctor.

What Is Abnormal Vaginal Bleeding?

Abnormal vaginal bleeding is bleeding from the vagina either in inappropriate amounts or at the wrong time during the month. To determine whether bleeding is abnormal and its cause, The duration, interval, and amount of vaginal bleeding must be taken into account.

The interval of the menstrual period can also be abnormal such as a woman's menstrual periods can rarely occur (oligomenorrhea) or more frequently (polymenorrhea). The amount of bleeding can also be abnormal; some women may experience too little volume (hypomenorrhea) others may have too much bleeding (menorrhagia).

  • Pregnancy - Abnormal vaginal bleeding occurs during early pregnancy before the women realize she is pregnant. But when vaginal bleeding occurs during pregnancy, it can cause pregnancy complications.
