Would an Extremely Strong Core Prevent Stretch Marks by Keeping the Size of the Belly Down?

Hi,

I'm not sure if this would work, but it certainly would not hurt. Best to you and your upcoming pregnancy! Let us all know how you do! Dr. H

Thank you for your question.  Yes, staying in great shape can help. Whether or not you get stretch marks though is a function of  how much stress is placed on your skin and what capacity your skin has to snap back. Preserving and protecting skin elasticity is key to preventing stretch marks.

There are thing you can control and things you can't control.

Things you can control are: How physically fit you are at the time you get pregnant, what your weight is at the time you get pregnant, how much weight you gain during pregnancy (follow your obstetrician's recommendations for healthy baby and healthy mom), and how good you are at getting the weight back off after pregnancy and keeping it off. Large and repetitive fluctuations in weight are a risk factor for stretch marks. This is why many women get no stretch marks after first baby but get them after the second or the third child.  The skin elasticity is gone and can't take it anymore. A good preventative measure is to keep your skin well moisturized during pregnancy, for example, with cocoa butter such as Burt's Bee's Mama Belly Butter.

Thing you can's control are:  The size of your baby.  The larger your belly gets, the more chance of stretch marks. Genetics.  If your mom got stretch marks from her pregnancy, then there is an increased chance you will too. Skin elasticity decreases with age. This is another reason why stretch marks happen after the second or third pregnancy, but not the first. Women are the youngest when they have their first-born child.  This is when skin elasticity is the best. Skin elasticity fades with age.  This can be prolonged with great skin care but cannot be entirely prevented.  It happens. This is why liposuction works better in the younger population (better skin quality) and not so well in the older population (lost skin elasticity). ....No, I can't tell you a specific cut off age between young and old. All I can say is that every year I get older, my definition of old increases by at least one year.

I hope this helps.

Thank you for the interesting question.

Unfortunately there is no evidence that  developing stronger/thicker abdominal wall muscles will necessarily prevent “swelling of the belly during pregnancy” and/or  stretch marks. It will certainly do no harm to  work out hard prior to pregnancy but don't be heartbroken if you develop stretch marks nevertheless.

Best of luck with your workout regimen and future pregnancies.
