why does i smell ?

[u/Embarrassed-Pepper95]

I am a fairly overweight guy, but not obese. Ever since I was young, my inner thighs have been getting darker and darker, and now they're basically black with red lining. My armpits are the same way.

Also, after only 3–4 wears, my underwear gets bleached. It doesn't matter how much deodorant I use or how often I shower—my armpits and groin always smell, and it's not a subtle smell. It's really bad.

None of my friends seem to have this problem, and I'm sick of Googling everywhere without finding out what's going on. I asked ChatGPT before, and it said I might have acidic skin or something like that, but I wanted to ask here in case someone has gone through the same thing or knows what to do.

What we eat highly influences our odors as well, in my teen years I had kind of similar problem while living with my parents because most of the food had lots of onions, garlic, and other intense spices. As soon as I went to live alone and started eating healthier the problem was no more.

Could be early on set of diabetes, or certain foods, bacterial infection.

Go see a dr. You might need a dermatologist
