This question I get a lot. If you have a question about chiropractic please ask in a comment. To the question, statistically yes. Regular chiropractic care has been shown to decrease the overall risk of complications and C-sections in recent research. Your chiropractor should not be a replacement for your midwife or OB/Gyn if you have one, but his treatments should be complimentary to regular pregnancy monitoring.
Chiropractic is a great way to treat pregnancy related back, muscle and joint pain. In that situation drugs are not the best option as most drugs can have unwanted or unknown side effects on the baby, not to mention the mother. The reason that pregnancies go better with chiropractic care seems to be the same reason that exercise improves your quality of life. If you improve the ability of the body to perform at its best things go wrong less often. Chiropractic can help to improve your bodies function. In the case of pregnancy the better prepared your body is to carry and deliver your child the less complications you are likely to experience.
Many patients appreciate regular chiropractic during pregnancy. I also recommend husbands come with wives to at least one pregnancy treatment as I can teach them many ways to provide relief when she can’t get in to see me. You can check out my site for additional info and useful links on this topic.
