I have a heartburn! Why?

Posted on 25 April 2017 by Kristrun

Relaxin is a hormone that does exactly what it says on the tin; it relaxes the ligaments in the pelvis and softens and widens the cervix, in preparation for childbirth.
What is relaxin?
Relaxin is a hormone that is secreted into the circulation by the ovary. the placenta, the membranes which surround the foetus, and the lining of the uterus. During pregnancy, relaxin levels are at their highest in the first trimester. At this time it is believed to promote implantation of the developing foetus into the wall of the uterus and the growth of the placenta. Early in pregnancy, relaxin also inhibits contractions in the wall of the uterus, to prevent premature childbirth. It also relaxes the intrauterine ligaments in order to provide enough flexibility for the growth of the baby’s living quarters.
Relaxin can regulate the mother’s cardiovascular and renal systems to help them adapt to the increase in demand for oxygen and nutrients for the foetus, and to process the resulting waste products. It is thought to do this by relaxing the mother’s blood vessels to increase blood flow to the placenta and kidneys. Towards the end of pregnancy relaxin promotes rupture of the membranes surrounding the baby and the growth, opening and softening of the cervix and vagina to aid the process of childbirth. There is also some evidence that relaxin can relax the ligaments at the front of the pelvis to ease delivery of the baby. There are several other factors involved in labour, but the exact trigger remains unclear.
What happens if I have too much relaxin?
Studies have suggested that high levels of circulating relaxin in the mother are associated with premature birth, presumably via its effects on the rupture of the fetal membranes and the opening of the cervix. However, further research is needed to confirm these findings. In addition sometimes it affects things you don't want relaxed. For instance, what happens when relaxin is working particularly well on your pelvic ligaments? – symphysis pubis dysfunction or the muscle that prevents stomach acid from creeping back into your esophagus becomes floppy?
