Hello dear, thank for sharing your concerns. Looking at the details you have shared, i think its a Pear(bell) shaped body you have, which at times causes intertrigo, a state where rash shows up between the folds of skin. It is a very common skin rash that can crop up throughout life. skin folds often rubs together and traps moisture and causes this condition. You need to get your body fat down as intertigo spreads if not treated well. That can be done with a structured supervised diets plan which i guess you are not having right now. Need not to worry. Please share your contact details on my facebook page named Dietitian Shreya or visit website www.dietitianshreya.com
