Why Does Period Blood Occasionally Turn Black? Causes of Black Period Blood

In the event that there are no underlying health difficulties FOR Black Period Blood, most people begin their period (menstruation) around the age of 12 or 13.

Menstrual blood can be any colour, from a vivid red to an orange, brown, or even a black. Black period blood, it should be noted, isn’t actually black; it’s just so dark that it appears to be black. While these differences are typically acceptable, occasionally the presence of black period blood can signal a medical issue that may require attention.

Black menstruation blood and discharge causes

Blood that has oxidised and taken longer than usual to leave the uterus is known as black period blood. Blood turns dark brown or blackish when it is exposed to oxygen, resembling the colour of coffee grounds.

Vaginal discharge and black period blood aren’t necessarily alarming symptoms. It frequently happens at various points during a cycle, especially just black period blood.

Sometimes, vaginal discharge might reveal important health information.

1) A period is beginning or ending.

At the start and end of a period, blood flow is often a little slower (just so you know, you can use our online period calculator to determine when that will be). Blood has more time to oxidise and transform into black period blood the longer it stays in the body.

2) The vagina may contain something that is stuck.

In addition to black period blood, an infection may also result in additional symptoms like:

Black Period Blood

  • unpleasant-smelling vaginal discharge;
  • discomfort or itching in or around the vagina;
  • rash or swelling of the genital region;
  • fever; difficulty urinating;
  • pelvic or abdominal pain.

If any of the symptoms listed above are present along with black period blood, you should seek medical attention right once if you have an internal obstruction. Rarely, it could cause toxic shock syndrome, a life-threatening infection.

3) Period blood has been kept

Occasionally, surgical complications such cervical atresia or the absence of a cervix (cervical agenesis) can also result in retained menstruation.

A severe obstruction may result in amenorrhea, which is the absence of menstruation entirely.

4) Cervical cancer is a potential

Typically, early-stage cervical cancer has neither symptoms nor indicators. Heavy, watery, bloody vaginal discharge with an unpleasant odour and vaginal bleeding that can eventually evolve into dark brown or black period blood are only a few signs of cervical cancer in its more advanced stages. Other warning indicators of cervical cancer in its advanced stages include:

Black Period Blood

  • • Fatigue
  • • Longer or heavier periods
  • Pelvic pain
  • Weight loss
  • Pain when having sex
  • Bleeding during or after sex
  • Difficulty urinating
  • Difficulty passing bowel movements
  • Swelling in the legs

5) Postnatal lochia is now present.

After some time, the colour gradually becomes yellow or creamy before the flow completely stops. In the weeks following birth, lochia that is brilliant red, has clots the size of plums, or has foul-smelling discharge should be examined by a medical professional.

6) There has been a miscarriage.

There may not be any other signs of a miscarriage, such as painful bleeding or copious bleeding, besides black period blood. A missed miscarriage happens when the embryo stops growing but isn’t ejected by the body; it can only be detected by ultrasound.

7) Implantation haemorrhage produced it.

However, dark blood following implantation haemorrhage is quite uncommon.

10 to 14 days after a fertilised egg implants itself into the uterine lining, implantation haemorrhage can occur.

In some pregnancies, implantation bleeding may not happen. Make careful to see your doctor if you do suffer implantation bleeding or believe you could be pregnant.

Is Normal Black Period Blood?

Black period blood is not a cause for concern, says ob-gyn Dr. Rebecca Brightman of New York City. It is quite typical to happen towards the conclusion of the cycle when the blood stays in the body for a longer amount of time.

The flow lessens once the uterine lining stops leaking. Slowly, the blood starts to leak. The remaining blood gets oxidised in the interim and produces a dark discharge in place of a period. The blood that remains is what darkens with age.

If it persists for two days, that is normal. If it persists for longer than seven days, you should seek medical attention right once.

Black Period: How Long Does It Last?

The black period frequently lasts up to two days. You should visit your doctor if you frequently observe black or dark brown blood at the conclusion of a period for any length of time.

Options for treatment of black menstrual blood

  • Fever, discomfort, and a black discharge are possible symptoms of a foreign object lodged in the vagina. It’s crucial to see a doctor as quickly as possible to have the thing removed.
  • The most common form of treatment for STIs and pelvic inflammatory disease is antibiotics. Finish the complete programme and adhere to all the recommendations.
  • If the menses are retained, surgery may be required to address the underlying issues that led to the obstruction in the first place.
  • Each patient-specific regimen of surgery, chemotherapy, and radiation is used to treat cervical cancer.

When to seek medical attention

Every 21 to 35 days, women experience normal menstrual bleeding, which lasts two to seven days. Outside of this range, black period blood may be irregular and has to be discussed with a healthcare professional.

It’s vital to go to a doctor if dark discharge appears during pregnancy, after delivery, or after starting menopause because it could indicate a dangerous underlying condition. If you have black period blood and any of these signs, you should see a doctor right away:

  • Vaginal itchiness
  • heavy or foul-smelling discharge
  • cramping
  • pain or fever

Conclusion for the Black Blood Period

Typically, black discharge at the start and end of your period is nothing to be concerned about.

A period typically lasts 3 to 10 days and happens once every 3 to 6 weeks. From month to month, it may vary. Outside of this general time range, bleeding or black discharge is seen as abnormal and needs to be handled with a doctor.

If you observe black discharge and you are pregnant or you just had a kid, go to the doctor. You should get medical help right once if you develop any additional strange symptoms, such as fever or cramps.

If, after entering menopause, you suffer black discharge or any other unusual bleeding, you should also see a doctor. This can be a sign of a severe underlying ailment.
