### Human:\nwhy does birth control cause you to gain weight? . i started birth control just 1 week ago and i've already gained 4 pounds! my eating is the same and so is my exercise so why am i gaining all this weight? is it water weight? if i stop taking the pill can i easily lose the weight?\n\n### Assistant: hi your find it the hormones somehow you will need to adjust your diet and increase your exercise program. its either a happy sex life by taken the pill or you will always be worried things are ok about his condoms and all the other problems concerning male sperm. just give it a couple more weeks to see how you settle down with it you could try changing brands. do hope this helps you. good luck
