Weight gain is more likely about 70% of women experience 10 lbs or more. Loss of bone density is also a factor and calcium suppliments should be taken. Mood swings or depression is also common. A decrease in sexual desire can also be a side effect. I actually had hair loss when I was coming off of the drug not while I was on it and I lost the weight. Fertility afterwards is an issue it can be 6-18 months for you to concieve.
In my expereince with the shot I lost about 30 lbs and keep it off the whole 5 yrs. I also noticed a loss of hair more than normal and mood swings really bad ones. Ialso craved foods I never did before. when I went off the shot everything calmed down but I put the 30 lbs back on plus about 15 more.
If you are talking about the depo-provera contraceptive injection the side affects vary with different people. I went on the injection for 7 months and during that time i put on weight, had stomach cramps and heavy bleeding for a majority of the time. The downside to the injection is that even if you get a top up on the injection the effects may not stop. The injection stays in your system for anything up to six months after youu stop getting it and the cramps and bleeding can continue long after you had the last injection. Personally i would'NT recommend it but you should enquire more information at your local GP or contact the Abacus centre
i got the depo back in January and it is now may. i had my period for at least 8 weeks, i still have not had them back. I have been told it can take up to one year for them to come back. i put on weight with the injection. i would not reccommend to anyone if im honest. But if you do need more information contact your local gp or health nurse.
