fødselskontraktioner

Fødselskontraktioner, also known as labor contractions, are the tightening and shortening of the uterine muscles during childbirth. These contractions are the primary mechanism that dilates the cervix and propels the baby down the birth canal. They typically begin as irregular, mild tightenings that may be mistaken for Braxton Hicks contractions, or "practice" contractions. As labor progresses, these contractions become more regular, stronger, and closer together.

The intensity of a contraction is often described in terms of the tightening sensation and the subsequent relaxation of the uterus. The duration refers to how long each contraction lasts, and the frequency is how often they occur. During a contraction, the uterine muscles pull upwards and inwards, causing the cervix to thin out and open. Once the cervix is fully dilated, usually to 10 centimeters, the contractions become more effective in pushing the baby out. Pain associated with contractions can vary significantly among individuals and can be managed through various pain relief methods. After the birth of the baby, uterine contractions continue to help deliver the placenta, a process known as the afterbirth.
