It's been said that if you have taken antibiotics, you have had a yeast infection. Although it's usually candida yeast. It happens in the gut and it happens to men, a lot. It happened to me and it took a month of no alcohol, no sugar, low carbs, and plain yogurt to shake it. If you have taken antibiotics, limit your diet afterwards to food that won't encourage yeast to bloom.
