There seems to be a correlation but its unclear why we all seem to get them.
Just lop those things off. I recently "de-tagged" myself with a sterile nail clipper set and some alcohol. It doesn't hurt and barely bled at all and now they're gone. I got rid of about 12 of them in all. I must admit I was very hesitant to do the first one but after the first, the rest were easy.
I seem to have them all around my Neck area.
I noticed my Father had them too and to my surprise his doc ran a thyroid test on him and he is Hypo!!! Of course he is reluctant to believe it so he saids he wanted to wait and run the test again in a few months.
My mother was loaded with them and had no thyroid problems whatsoever. I have a ton of them and assume that I inherited the trait from her. I have read that those of us with skin tags are more prone to colon polyps. I had one removed from my stomach during an endoscopic exam a couple of years ago.
I was told and have read that skin tags are caused by high insulin levels. In fact, one time at a gynecologist's office---she lifted up my hair, saw the tags and said I had PCOS. I said "you mean you know that from looking to see if I had tags?" she said yep. Too bad she didn't have her crystal ball that day to find my thyroid problem.
I had mine off in a dermatologist's office and all she did was numb them with a needle and clipped them off. These were pretty big. But when I see a new one now, I just clip it off, let it bleed for a little while and it's gone.
Im a guy so Im not quite sure that has everything to do with it, but my cortisol is high and so is my TSH. My wife was ready to kill me when I done taking them off. It looked like someone sliced me with a machete from my armpit to my chest. They didn't bleed a ton but they do bleed a little at first and since I did so many, I literally had blood drippin down my chest....it was kinda cool actually but my wife almost passed out when she saw me.
I got rid of a crop of skin tags on my neck, armpits, & chest by using the blowdryer on them twice a day for 10 days to 2 weeks.
NOTE: This method is not recommended for larger tags. Do not use the blow dryer repeatedly near the eyes. You might want to try the method on just one tag first to see if you are comfortable with it.
Blowdry (on highest setting) a damp tag until it tingles (maybe 30 sec.) then go on to another one, heat it until it tingles, then come back to the first ... Make sure each one you are treating gets 2 -3 shots each time you have the blower out, and make sure each "shot" is done until you get the tingle.
After a few days some of the tags will start to enlarge. Keep blowdrying them. They may get to 2-3 times their original size. Soon they start to shrivel up. Keep blowdrying. Soon they they fall off.
No bleeding. This method is quite clean, but in the enlarged state the tags can be tender to the touch.
Having had dermo doc freezing for skin tags done in the past, I would say the discomfort is very similar with the 2 methods. The blow dryer is cheaper, but I think you need a dryer that will get really hot to make it work. A blow dryer from the 1970s might not work.
Could there be any precaution for blow-drying over the thyroid area at the front of the neck? Maybe -- ck with your doc.
As for cause, I tend to have skin tags recur when I eat more sugar. If I keep to a low GI diet, I keep them at bay (I am not diabetic).
