Does fast weight loss affect the effectiveness of your birth control?

Question by simpleheartsx3: Does fast weight loss affect the effectiveness of your birth control?
I am on the depo shot and recently had weight loss surgery. The weight loss from the surgery has caused lots of heavy spotting (which has never happened before on the depo shot with me). Is the weight loss counteracting the effectiveness of the shot?

It is possible to lose weight rapidly but you should be realistic and take on board that if you lose weight quickly then you will inevitably put it all back on again just as quickly. I lost 5 pounds over the past few weeks when I had a special celebration to attend, and I did it by following the instruction supplied on the site in the box below.
