For me it was a hormone imbalance. I started using over the counter progesterone cream (comes in prescription strength as well). According to the directions on the jar (I actually use less, about 1/2 reccomended). For me the "onion B.O." went away almost immediately. Talk to your doctor first to make sure it's OK for you.
hi, its definitely in the intestines, this disorder baffels everyone including the most experienced doctors, a gastroenterologist is the person to see, but i dont know whether they will help you. personally i would suggest you mix one tea spoon of bicarbonate baking soda in 375ml glass of tapwater and drink this every two days for a couple of weeks- seven glasses in fourteen days.
