Patient discussion about birth cohort.

Q. BIRTH CONTROL how many types are there?

A. there are many types,pill,shot,condom,marina,sponge,tubes tierd,vastectomy,with draw,no sex,etc.

Q. What are the risks of C-section? See that all the pregnant movie stars are having C- sections instead of natural child birth. Maybe I should have one too, instead of giving birth regularly? Are there any risks?

A. Most mothers and babies do well after C-section. But it is important to remember that it is major surgery, so it carries more risk than a normal vaginal delivery. Some possible risks of C-section include:
• Infection of the incision or the uterus.
• Heavy blood loss.
• Blood clots in the mother’s legs.
• Injury to the mother or baby.
• Problems from the anesthesia, such as nausea, vomiting, and severe headache.
• Breathing problems in the baby if it was delivered before its due date.

Q. Is there any natural supplement for birth control pills?? there has to be!!! I'm tired of puting chimicals in my body.. maybe something from chinese medicine?

A. any natural material when coming in large quantities can damage. sex hormones are a natural thing. chines medicine does not have something more "natural" then the body regular hormones.
