The down side of losing a lot of weight quite quickly is that people can be left with a large amount of excess saggy skin which can overshadow the achievement of getting to a target weight.
Even with regular exercise this can often be a problem but if for example a person has lost weight through having a gastric band implanted into their stomach then the problem of too much skin will be a fairly common one. It is a reason why any kind of rapid weight loss should be avoided.
If exercise is not making any difference then the alternative could be cosmetic surgery, which although quite expensive will give someone the body that they have wanted and make all their efforts worthwhile.
Any surgery of this type requires a local anesthetic so should not be undertaken lightly.
A good surgeon will put you at ease and explain how the operation will be performed and what risks are involved.
Cosmetic surgery can be very successful at removing ugly skin around the stomach and upper arms which is usually where the problems lie.
Do plenty of research when finding a plastic surgeon that is right for you, if possible get a recommendation from someone you know quite well.
Make sure you are completely happy before you commit to anything, including hefty deposits and the signing of consent forms.
