BLI-tehd OH-vuhm

What causes blighted ovum?

In most cases, the cause is abnormal chromosomes in the fertilized egg. Other possible causes include:

• An infection.

• An autoimmune disease in the parent.

• An endocrine disease in the parent.

• Tissue that divides the inside of the uterus into sections (septum).

Symptoms of blighted ovum

Symptoms of blighted ovum include:

• Mild cramps in your lower belly.

• Light bleeding from the vagina called spotting.

Treatment for blighted ovum

After a pregnancy loss, the placenta and sac need to leave the body. The process can cause pain and bleeding. This can happen on its own, or your body may need help. Your health care provider may advise any of the treatments below:

• Expectant management. This means to watch and wait. If it’s safe for you, your provider may advise waiting several weeks to see if the placenta and sac are released from your uterus on their own.

• Medicine. The medicine misoprostol can help the process. You may take the medicine by mouth. Or it may be put into your vagina. You may also be given pain medicine to help lessen cramping.

• Uterine evacuation/curettage. You are given pain medicine, plus medicine to help you relax and feel sleepy. A tube is put through the opening of the vagina and cervix. The tube is attached to a vacuum device. The device creates suction that helps remove the tissue. In some cases, a tool called a curette is used to help loosen tissue in the uterus.

After or during the treatment, you may need to have an ultrasound test. This is to make sure all the tissue has left your body.

You may also need emotional support during and after this process. Losing a pregnancy can be very upsetting. Talk with your provider and your family to get support if you need it during this time. You may want to speak with a counselor or attend a support group. Make sure to ask for any help you need.

Possible problems from blighted ovum

Possible problems can occur from treatment. These include:

• Excess bleeding.

• Infection.

• Scar tissue.

• Tear in the uterus (perforation).

When to contact your health care provider

Contact your provider right away if you have:

• A lot of bleeding from your vagina.

• Dizziness or fainting.

• Fever of 100.4°F (38°C) or higher, or as directed by your provider.

• Other symptoms that don’t get better or get worse.

• Severe pain that isn’t helped with pain medicine.
