My DR isn't concerned about it, but none the less, I have started HRT at age 21, and there have been changes to my body in what appears to be changes primarily to my hips and floating ribs. It almost looks like my floating ribs have shrunk a little bit, and well, I started HRT with hips, and they are now a good 40 inches, so I am actually developing a figure, and hopefully I will have a summer body come Christmas.
I'm not sure if these changes have occurred to my bones, or if it is just distribution but hey, I don't really care, so long as I have a summer body soon, I am now living 10 minutes walk to the surf beach so YAY!!! Hot surfers to flirt with!

My measurements are;
43inch shoulders, 40 inch hips and 32 inch waist.
I have a bit of puppy fat just below my waist, and well, I am going to start Zumba in the next week or so, so we'll see my body tone up like mad
