Question

What is labour pain, how and when does it occur?

Answer 1

Hint: It is the expansion of the uterus that occurs at the time of childbirth. It causes pain in the lower abdomen.

Complete answer:
- Parturition implies birth. Childbirth is the climax of pregnancy, during which a child develops within the uterus of a mother. Childbirth is termed labour as well. Roughly nine months after childbirth, pregnant humans go into labor. Parturition is caused by a complex neuroendocrine process.
- Parturition has 3 stages and they are dilation, expulsion, and placental. The first period of parturition is dilation occurs with the onset of labour. It persists until it completely dilates the cervix. This dilation is divided in two sections and they are latent and active.
- At total dilation, the second stage of parturition is expulsion which begins at full dilation and lasts until birth. After pregnancy, the third stage of parturition i.e., placental, begins and finishes with the afterbirth delivery.
- By the end of labour, vigorous contraction of the uterus causes foetal evacuation, contributing to labour pain.
- Prior to birth, labour pain occurs.
- Due to the contraction of muscles, it happens.
- The wave-like motion from the top of the uterus to the bottom is the process.

Note: The uterus is a muscular organ that expands to push the baby out firmly, and the main cause of labour pain is those contractions. It causes pressure on the back, perineum, bladder, and bowels, in addition to extreme muscle contraction in the abdomen and, also occasionally, in the entire torso and pelvic region.
