Physiological abdominal pain in pregnancy:

In early pregnancy, due to hormonal changes in pregnancy and an increase in progesterone, the uterus will relax. The effects of these hormonal changes on the uterus will be a reduction in uterine contractions and loosening of the ligaments that support the uterine ligaments.

Low back pain following the threat of miscarriage

There are crampy pains in the abdomen and pelvis that are gradually increasing in number. These pains will be accompanied with vaginal bleeding, sometimes tissue fragments may be seen in the excreted blood. Immediate referral to equipped medical centers is necessary in these cases.

Sudden lower and left abdominal pain during pregnancy

Take the following two important reasons seriously:

  1. Left ovarian torsion:

If the left ovary twists around its own vascular base, ovarian torsion occurs. Sometimes the left ovary and fallopian tube both wrap around the vascular base. In left ovarian torsion, blood supply to the ovary will be cut off by twisting the vascular base of the ovary.

Not getting enough oxygen to the ovaries will cause a sudden, severe pain in the lower left side of the abdomen that is unbearable.

Ovarian torsion is very common in young women. Ovarian torsion can cause death and loss of the ovary if prolonged blood supply is not checked and treated in time.


  1. Ectopic pregnancy:

In a normal pregnancy, the fertilization product cell delivers itself from the fallopian tube to the uterus after several divisions, which means that fertilization is usually done in the fallopian tube, but after a few days this product arrives in the uterus after several divisions and will be implanted in the uterine wall.


In ectopic pregnancies, the fertilization product does not enter the uterus and remains outside the uterus, which in 98 percent of cases is the fallopian tube. In ectopic pregnancies, the fetus will die. Because not enough nutrition and proper placenta will not be formed,

In addition, there will be no place for the fetus to grow. As the gestational age increases, and the fetus grows, there will be pain in the lower and left abdomen of the pregnant mother.

In ectopic pregnancy, despite a positive pregnancy blood test, the intrauterine pregnancy sac is not detected on ultrasound.

In these women, the sudden onset of severe pain on the side where there is an ectopic pregnancy is equivalent to a ruptured fallopian tube or an ectopic pregnancy.

manifestations or complications of external pregnancy have not been diagnosed and treated:

In ectopic pregnancy, as opposed to the threat of miscarriage, the predominant symptom will be lower and left abdominal pain, meaning that the pain is more prevalent than vaginal bleeding.


What are the diagnostic measures needed to evaluate lower and left abdominal pain in pregnancy?

Treatment for ovarian torsion, infectious diverticulitis, ectopic pregnancies should be done immediately.
