For those who are concerned about the safety of weight loss pills, body-shaping underwear seems to be a better choice. However, doctors caution that these hot-selling figure fixers also have their share of health risks.

To look better and slimmer, many women are willing to endure the discomfort from wearing body-shaping tights for long hours.

Although the majority of body-shaping tights are flexible fabrics such as silk, cotton or lycra, buckles and strings are also used to make the body look tighter.

Wearing such clothes for long hours would cause skin rash and other skin problems.

Some people can't even eat or suffer from heartburn.

Doctors advise patients with diabetes or skin problems to avoid wearing such clothing to prevent worsening their conditions.

And for people without any health problems, they should limit the time of wearing body-shaping tights to no more than 1 hour a day as it may cause bad blood circulation.
