Steroid use is when actors take a medicine called steroids to make their muscles bigger and stronger. In Bollywood, some actors try to look very muscular and fit, so they use steroids to help them.
But using steroids can sometimes be bad for them. When a person takes steroids, it can have bad side effects like making them angry or moody, causing acne, or even damaging their heart or liver.
So, it's important for Bollywood actors to be careful when they use steroids, and they should only do it with the help of a doctor who can make sure they don't get hurt. It's also important for them to remember that looking fit and healthy comes from eating right and exercising, not just taking steroids.
