Miscarriage is the spontaneous loss of a pregnancy before 20 weeks. Usually miscarriage happens because the fetus isn't developing as it should. Miscarriage is common. About 15% of pregnancies end in miscarriage, usually before the 12th week of pregnancy (during the first trimester). Some miscarriages happen even before a woman knows she is pregnant. Miscarriage can be a traumatic, emotional experience. Most women who have miscarriages go on to have successful pregnancies later on. A second miscarriage occurs in only about 1% of women. However, some women may have multiple miscarriages. Signs and SymptomsSigns and symptoms that often happen with a miscarriage include:
What Causes It?Normal activities (like work, exercise, or sex) won't cause a miscarriage, nor will nausea and vomiting (even with severe morning sickness). Most often, a miscarriage happens because there is a problem with the baby's genes. But some health conditions can make the mother more prone to miscarriage, including:
Who Is Most At Risk?Women with the following conditions or characteristics are at greater risk for having a miscarriage:
What to Expect at Your Provider's OfficeIf you think you are having a miscarriage, see your doctor immediately. Your doctor will do a pelvic examination to check for any problems with your uterus and see if it has begun to dilate. Your doctor will do an ultrasound to check on the baby's heartbeat and see how it is developing. If you have miscarried, your doctor may do a blood test to make sure there's no tissue is left inside your uterus. Treatment OptionsPreventionIn most cases, there is no way to prevent a miscarriage. You can avoid known risks, such as:
Keep your body healthy by eating well, exercising regularly, and getting enough sleep. Your physician may also prescribe bed rest and progesterone if you have experienced previous miscarriages. Take thyroid and other medications as prescribed, and consider supplementing your diet with folic acid and vitamin D. Treatment PlanIf you are threatening miscarriage, your doctor may tell you to rest and avoid sex and exercise. If your cervix is dilated and your uterus has started to contract, the miscarriage can't be stopped. In that case, your doctor may give you medication that causes your body to get rid of the placenta and tissue from the pregnancy. If any of the tissue remains inside your uterus, your doctor will perform a dilation and curettage (D&C), which involves dilating your cervix and gently suctioning out the tissue. If you have a history of unexplained miscarriages, in vitro fertilization, embryo transfer, or artificial insemination may be used to achieve a successful pregnancy. Drug TherapiesIf you have an underlying medical condition, or have had multiple miscarriages, your doctor may prescribe medication to encourage a successful pregnancy. This medication will depend on what your specific health problem is. Surgical and Other ProceduresDilation and curettage (D&C) can remove pregnancy tissue if it is not expelled naturally from the uterus. Other surgical procedures may help problems with the uterus. Complementary and Alternative TherapiesKeeping your body healthy may lower your risk of a miscarriage. Before getting pregnant, it is a good idea to discuss the risks of miscarriage with a counselor, including the importance of staying healthy and avoiding caffeine, alcohol, and recreational drugs. Miscarriage is a serious health issue. Ask your doctor about alternative therapies that may help you stay healthy during pregnancy. Never take any herb or supplement while you are pregnant without checking with your doctor first. Nutrition and SupplementsThese nutritional tips can help you stay healthy before and during pregnancy:
Pregnant women may need these nutrients:
HerbsDO NOT use herbs during pregnancy unless you are under the care of a qualified health care provider. Work with your doctor to determine which herbs may be right for you. HomeopathyNo studies show that homeopathy can prevent miscarriage. However, homeopathic literature does have reports of women who have had successful pregnancies after miscarriage when being treated with homeopathy. An experienced homeopath would consider your individual case and may recommend treatments to address your underlying condition and support your overall health. Prognosis and Possible ComplicationsMany women who have one or two miscarriages go on to have successful pregnancies. Women have only a 1% chance of having another miscarriage after the first one. However, the risk goes up with each miscarriage. Possible complications include infected pregnancy tissue that could lead to pelvic abscess, septic shock, or even death. Many women feel depression or guilt after a miscarriage. A support group or individual counseling may help to deal with these feelings. Following UpYour doctor will monitor you until the miscarriage is complete. If you have had a miscarriage and become pregnant, you should see your doctor right away.
