Pregnancy Causes Hand, Feet, Extremity Increase In Length And Width And Height Increase (IMPORTANT)

When I was doing research for my post on the possiblity of injecting GH or BMPs into the feet to increase it’s size, I seemed to have come across a very interesting phenomena which might help a little in our search. It turns out that during and after pregnancy, the women often has her hands, feet, extremities enlarge in size, and that size increase never goes away.

You can see from all the comments that this is a very common phenomena. The comments by other mothers on the link at Baby Center continues for 5 more pages all telling their stories. There seems to be this hormone relaxin which loosens the joints in their feet, causing the foot bone sto spread. However, that doesn’t seem to explain why it is that even after pregnancy, the feet stays in that enlarged size. I wonder whether it might also be that the very bones also thickened and lengthened in size.

The stories show that the fingers get thicker. The feet gets longer, which could indicate either the feet being squeezed and spread out, or maybe the bones are indeed getting longer.

The most crazy comment I saw from the post was on the second page (link HERE) where the mother said this!!

Update: It seems that a 2nd mother posted that she had grown taller during pregnancy as well on the 4th page of comments!! (HERE)

I too went up a size in shoes for each pregnancy (from a 7-9) but also grew 1 1/2″ in height at 24! Now that my third pregnancy is occurring at 28, I am fairly sure I won’t be getting any taller, but I also hope I don’t go to a 10…

Analysis: Now I know that when females are going through pregnancy, they have all this hormone going through their body. I an accept the idea that their fingers and feet get enlarged and engorged. I am also proposed and accept the idea that maybe one of the hormones going through their system can cause even the long bones to thicken and get wider. This could mean that the metatarsals in their feet expanded radially making them even 3-4 millimeters taller. However this women who commented says that her pregnancy caused her to grow 1.5 inches in height at 24! What is going on?? I am very confused because that is not supposed to happen from what we currently understand. It reminds me again of the Tanya Angus and Kosen cases before. In a previous post I had created a theory that if you expand your stomach and torso out to stretch out your vertebrate it could theoretically cause some height increase. However a pregnant women’s expanded stomach should actually decrease her height because her lumbar region is pulled further downwards. If this story is accurate, it is another example of the idea that extreme hormones may cause some height increase even after physical maturity. Update: 2nd mother has commented that she also grew 1.5 inches in height with a shoe size increase from 7 to 8.

Expert Answers

I think my feet have grown. Is this possible?

Jane Andersenpodiatrist

Yes. As you’re discovering, your belly isn’t the only thing that gets bigger during pregnancy! This is partly due to pregnancy weight gain and swelling from the extra fluid your body retains while you’re pregnant (called edema). To ease the swelling, soak your feet in cool water and prop them up as often as you can.

But there’s another reason that feet seem to grow during pregnancy. The aptly named pregnancy hormone relaxin, which loosens the joints around your pelvis so your baby can make his way down the birth canal, also loosens the ligaments in your feet, causing the foot bones to spread. Your foot bones aren’t actually growing — it’s just that the ligaments that hold these 26 bones together aren’t as tight as they were.

You may notice your shoes getting a little tight as early as the second trimester, and they may continue to increase in size until late in pregnancy. While the foot swelling generally subsides within a month after delivery, any foot spreading caused by looser ligaments is permanent. I estimate that half the moms out there wear shoes a half or a whole size bigger than they wore before having babies.

The bright side, if there is one, is that you get to buy new shoes! Buy a few pairs of comfortable, roomy shoes to wear during your pregnancy, but be aware that you may have to go back for more once the swelling settles down and your shoe size stabilizes about a month after delivery. Whatever you do, don’t try to make do with your old shoes! Wearing tight shoes can aggravate bunions and cause a host of painful foot problems, ranging from ingrown toenails to corns and calluses.

Finally, since feet tend to grow with each pregnancy, you may want to hold off on those pricey Jimmy Choos or Manolo Blahniks until you’re finished having babies.

Before pregnancy I had big feet already because I am 6ft and wore size 11 1/2 or 12. After the pregnancy of my first daughter I could only wear a size 12 and sometimes they were a little snug. After the pregnancy of my 2nd daughter I can only wear size 13. I am now pregnant with our 3rd child and wondering what shoe size I will be in after this pregnancy. Talk about hard to find shoes that aren’t super expensive.

I am so glad I saw this, and I wish that some doctors would tell you this because it would have saved me a lot of pain! I couldn’t figure out why I was having terrible ingrown toenails. Being a nurse I finally figured out that it started when I stopped wearing flip flops. Definetly can’t wear ANY of my pre pregnancy shoes anymore. My beautiful wedding ring needs to be resized too, oh bother! Thank you for this post…i feel sooo much better that it wasn’t just me.

Trying to buy new shoes definitely isn’t a bright side when you were already a 5’11” woman who wore a size 11W before getting pregnant and now find yourself searching for the elusive 12W. I’d be better off trying to cobble my own shoes. It’s almost as if manufacturers think that the bigger your feet are, the less taste you have. I don’t want to wear shoes even my grandmother would be ashamed to wear.

Yep, my feet grew a full size while I was pregnant and have settled to a half size bigger (gave birth 8 months ago). I’m also finally coming to the realization that my fingers have grown too. I’m just about at pre-pregnancy weight and I still can’t get my wedding rings on my finger.

Mine also swelled up with my pregnancy, and unfortunately never swelled back. That wouldn’t be so bad if I were a size 7 or 8 to start with, but I’m 6’1″ and already wore a 12 which was next to impossible to find off the rack. Now I wear a 13, and well, that’s even harder to find, unless I want to wear shoes that make me look like a granny or a lady of the night. *sigh*

My mom and my aunt told me about this happening but but all my friends were like…”I’ve never heard of that” And thought I was just cracking jokes or making it up. I started out at size 7-7.5. After my first daughter I could no longer fit a size 7. I brushed it off as “well that must be how the shoe is made” Now after my 2nd daughter my shoe is a size 8. I attributed my new shoes size to the extra weight I had put on with the baby #2. Now with my new found realization I must no longer hope to fit in those heels in the garage…. You can find them on ebay (someday). DAMN YOU HORMONES!!!!!!

    “This is partly due to pregnancy weight gain and swelling from the extra fluid your body retains while you’re pregnant (called edema).”

    Hydrostatic pressure is known to be height chondroinductive. Perhaps the edema results in new growth plate formation. Quite a great find please do more studies on this. Maybe you can even find x-rays of females whom this occurred too.
