Can yeast infections cause weight gain?

I have been struggling with yeast infections for about 5 years during this time I have gained a significant amount of weight. I am fighting to keep from gaining anymore weight. I have been asking my doctor about Candida, with no real answer on what exactly it is. Could someone tell me. I honestly eat fairly healthy and try to stay active. I have stopped seeing my OBGYN doctor because I was quite offended when she told me I needed to lay off the fast food and lose weight. I have not found a doctor yet that I like. If I go to a family doctor would they be able to help me figure out what is going on with me. It is tiring and uncomfortable having yeast infections 6-8 months out of the year, sometimes multiple infections a month. But my real question is could my yeast infections have anything to do with my weight gain?
