Possible cause of the weight losswas the nausea as the side effect of these pills, which affected the appetiteof women.
Female sexual hormone estrogen is responsible for the waterretention in women using contraceptive pills.

On theother hand, the birth control tablets with norethindrone (Ortho Novum 7/7/7) haveincreased risk of unwanted weight gain.
