In the last month I have noticed a change in my sweat odor. In the middle of my chest, and areas where hair is located on my body either smells like something sweet or like onion (I don t eat onion) even after 2-3 baths a day (sweat odor one hour after each bath). The CHANGES these past few weeks have included: 1) I have stopped smoking regular cigarettes and started using nicotine gum and e cigs...; 2) due to my work schedule, I have been eating fast food every other night; 3) I have been under a lot of stress; 4) I have started using a diet supplement called W700 thermogenic; and 5) I have been drinking a lot of coffee, not enough water. I have never had this issue before. What could be the cause? My health is fine other than high BP. I have also been light headed every other day (started one month prior to sweat odor issue). Online it says sinus, liver or kidney issues. Also it says something about apocrine gland issues. Please help!!!
