The WHO has put "gaming disorder" on its list of diseases. Gaming disorder happens when people cannot stop gaming. It becomes more important than everything in life. Someone with gaming disorder will play even if they know they have big problems. Gaming disorder happens if problems continue for a year.

The WHO said doctors should know that gaming can be a danger to people's health. It can lead to big problems. Most gamers don't have a problem. However, some doctors believe that too much gaming is not a mental illness. One doctor said it is like coffee addiction. Not many people have problems because of coffee.
