Uterine contractions can be caused by several factors:
- Menstrual Cycle: During menstruation, the uterine lining sheds, causing the uterus to contract. These contractions are often felt as menstrual cramps. - Pregnancy: As the pregnancy progresses, the uterus contracts to accommodate the growing fetus. - Labor: The most significant contractions occur during labor, helping to dilate the cervix and push the baby through the birth canal. - Hormonal Changes: Hormones like oxytocin and prostaglandins play a key role in stimulating uterine contractions.
