Generally people with gambling addiction may face depression, migraine, distress, intestinal disorders, and other anxiety-related problems. As with other addictions, the consequences of gambling can lead to feelings of despondency and helplessness. This is a disease which opens gate for other diseases.
You are going to suffer from all of these symptoms if you are losing a lot of money and you spend a long time that takes most of your time, but if you are a responsible gambler I doubt something like this will happen, it's a good break away from longer works in your office and it will not hurt if you win a small amount while enjoying the games.
