Back pain and miscarriage are related only in that it is commonly reported that severe lower back ache can occur during the miscarriage process. This is typically accompanied by other symptoms, as a back ache alone does not signal a problem in most pregnancies. In fact, lower back ache and soreness is a common symptom of a healthy pregnancy.
The number of women who experience back pain together with a miscarriage is relatively high, although other symptoms are far more common. Other indicators of a miscarriage are bleeding from the vagina, sudden loss of pregnancy symptoms, and severe lower abdominal cramping. Once the miscarriage has begun, the cramps and back ache may come in intervals simultaneously, much like in a full term pregnancy during labor.
Women who experience back pain and miscarriage at the same time may have a tilted uterus or the baby may be pushed against the back if it is large enough to do so. During a miscarriage, women are typically given pain medications to help alleviate the symptoms, but these are not always effective for all women.
Severe back pain without the occurrence of other symptoms does not always signal a miscarriage. Some level of back ache is normal in a healthy pregnancy. This is first caused by the loosening of the joints and other muscles and then due to the weight of the baby pulling on the back muscles. Pain early in pregnancy is generally mild, although every woman experiences her symptoms differently.
In some rare cases, back pain and miscarriage may be the only symptoms of pregnancy loss before bleeding occurs. Pain may only be a dull ache and then progress into more severe spasms, although this is not always the case. Sometimes back pain is not present at all. Other times, there are not symptoms of miscarriage at all until bleeding occurs.
Having one miscarriage does not indicate that a woman will suffer another. Pregnancy loss in the first trimester is relatively common and does not always indicate a problem with fertility. Multiple miscarriages should be investigated further to rule out the possibility of genetic abnormalities or physical problems with the uterus or cervix. In most cases, it is thought that early pregnancy loss is due to a severe developmental issue in the fetus which causes life to be impossible outside the womb. This causes the body to abort the pregnancy naturally to ensure the survival of the species.
