How do babies give the signal to our preg. body and make contractions start?

Question

What causes contractions to start?:s ....im due today but I still dont see any baby:(

Answer 1

So I was watching this show on the National Geographic channel called "In The Womb" and it said that when the baby's lungs are fully mature it sends out a signal for the body to discontinue producing progesterone (the pregnancy hormone) and that's what causes your body to try to expel the baby.

Neat, huh?

Answer 2

Good luck with the baby!

Labor contractions are the periodic tightening and relaxing of the uterine muscle, the largest muscle in a woman's body. Something triggers the pituitary gland to release a hormone called oxytocin that stimulates the uterine tightening. It is difficult to predict when true labor contractions will begin.

Contractions are often described as a cramping or tightening sensation that starts in the back and moves around to the front in a wave-like manner. Others say the contraction feels like pressure in the back. During a contraction, the abdomen becomes hard to the touch. In the childbirth process, the work of labor is done through a series of contractions. These contractions cause the upper part of the uterus (fundus) to tighten and thicken while the cervix and lower portion of the uterus stretch and relax, helping the baby pass from inside the uterus and into the birth canal for delivery.

Answer 3

A babies body releases a hormone that tells our bodies to release the chemical that starts contractions. So when they say only the baby knows when she will be born they are serious. I just read about this recently, until then I had no clue that the baby actually releases a chemical. Everybody elses comments could help labor start, but if she's not ready to come then she wont. I know reaching your due date seems like you've been pregnant for an eternity, but it will be over soon!!! remember you wont go past 42 weeks so hang in there.

Answer 4

When the baby is ready to be born, they will become excited and a chemical is passed from the baby to the mother that starts the contractions. Also pitocyn is a chemical that is naturally released by our bodies that will make the contractions come more and more frequently.

Hang in there, I was 9 days late before labor was induced. It is difficult to do and waiting is the hardest. Even after stripping membranes, exercise, raspberry leaf tea, stress, hot weather, none of that will work like your baby just being ready to be born.

Answer 5

I've read that labor begins, usually -- in the best of cases -- when the baby can no longer get the fats and other nutrients it needs in the womb, and has to endure emergence / birth to get to what will satisfy its ravenous nutritional requirements (boobs! :)). the other responder who suggests that lung maturation plays a part is also correct. exactly how these chemical signals are sent, the ones that trigger labor, i don't know. hormones, likely ... hormones are the fedex of the human body. i think it's incredibly interesting.

And best of luck on your delivery!! I hope it's a beautiful experience for everyone involved :)

Answer 6

Determining gestation is a very imprecise science. Doctors give their best estimate for the arrival of your baby, but they are only human. Your doctor may choose to induce labor if they believe it is safe for you and your child. Labor can be stimulated by a variety of sources, and unfortunately I'm not certain all that precedes natural labor. I do know that after nine months you are anxious to see your child in this world, and I wish you comfort in these last few hours or days as well as a speedy delivery. Congrats!

Answer 7

exercise is right! and $ex will do it also. the mans $perm breaks down the plug (the mucus in your cervix), which makes it come out and stimulates the contractions. I am not sure how exercise works but it does. also raspberry tea has been known to work, make sure it is the leaves. good luck and congrats. I am a mother of 2 and about 18 weeks behind you on my third.

blessed be

Answer 8

Exercise...easier said then done right! But be as active as you can be at this point...Oh and congrats on the addition!

Answer 9

They probably don't, or there would be fewer premature babies than there are. So, the mechanism almost certainly lies in the mother -- but, what it is, nobody knows.
