Dark patches of skin, improvement after WLS?

I really HATE the dark pactches of skin that I have in several areas of my body including my neck. It does not matter what I do, how hard I scrub, I put alcohol on it, I have tried everything, IT WILL NOT GO AWAY! My surgery is next month, I was wondering if there is an improvement with this problem after surgery and if yes when do you start noticing it? THANKS!

I have the same problem, its called "acanthosis nigricans" I've had it since elementary school. A few years back when I lost about 60 pounds it was starting to fade, I ended up gaining that weight back and it came back, so Im hoping it will do the same this time around.

 Are you having surgery? What stage are you in? 

Yes, Im pre-op.. Still have to have a EGD the my files will be submitted to insurance for surgery.

As long as surgery helps with your insulin resistance it will dissapear.

Thoes patches are caused by insulin resistance in your body. You may not be Type 2  but you can still have some insulin resistance.

It will go away. Had that problem I'm 6 years post-op and no signs.

 Mine have cleared up, six months out. They were never super dark or patchy, though. The skin on my neck and elbows was a little darker than the rest of my skin, but I'm rather even-toned now. :D

Mine just look like I don't wash my neck LOL!!! This is great to know though, I did have this doubt. Thank you everyone!

hey there....after SURGERY I had a dark patch on my neck. i tried to scrub it and also tried all types of products and it never went away. i finally went to the dermatologist and was given a prescrition. IT WORKED!!!! the doctor said it was a sign effect of weightloss, he gave me the name of what it was called, but i cant remember. whatever its called, it also causes hair thining and dark patches on your body.
