Hey everyone. For the past couple of years I have been noticing an increase of stretch marks on several parts of my body ( buttocks, hips, thighs, inside of knees, breasts) I do not fall under any of the categories that would make it normal for me to develop stretch marks: I am 23 years old, well past puberty, I have never been pregnant or taken medications. My weight has not fluctuated, and I have a decent diet and exercise regularly ( but not to the point where I have huge muscles that can cause stretch marks.) I first began developing this problem 5 years ago, when I was 18 years old. Prior to that I had gotten a couple of stretch marks on hips and butt when I was 14 and going through puberty. These really did not concern me, because I knew there was a reason for them. They appeared bright red, then gradually became white. These were the only marks that appeared on my body. However, when I was 18, I began to notice some faint marks on my inner thigh. I wasn't sure if they were stretch marks, and I ignored them. However, a year later they became significantly worse, and I also began to develop them on inner knees and breasts. I went to some dermatologists when I was 20, they all said that these marks were completely normal, and were simply appearing because I was still growing. In all honesty, they all dismissed my problem, got me out of their office quickly, and made me feel stupid for going to them for a silly stretch mark problem.Well, i am now 23, I doubt that I am still growing, and these stretch marks have gradually gotten worse each year, and new ones continue to appear. Like I said, I have not gained or lost any weight. I am really worried that there is an underlying problem behind all of this. I just don't think it's normal for stretch marks to be appearing for no reason. I wouldn't be complaining if I had gotten them as a result of weigh gain, puberty, or pregnancy, but to just have them continue to get worse drives me nuts. In addition these marks do not appear red like the ones I got during puberty, they just seem to appear.. as faint lines that I can barely see which gradually get more white and prominent. Any suggestions on what kind of doctor I should visit? Obviously not a dermatologist... I was thinking that this problem may be hormone related, so maybe and endocrinologist? Other symptoms that I have include:fatigue, dry skin,chronic back and neck pain,extreme pms, high levels of stress and anxiety, mood swings,difficulty concentrating .Don't know if these could be related to my stretch mark problem, but just thought, I'd include them. I also read that high levels of stress can cause high levels of cortisol in the body, which negatively affect collagen production,,, so i don't know if that might be part of the problem. Anywhoo, sorry for making this post so long. Hope I receive some comments, suggestions, I'd greatly appreciate it!
