Decrease in overall productivity of individual: Addiction reduces the value that you add to wherever you are engaged career wise as you are mostly distracted with gambling thereby reducing your commitment and dedication to your duties, this might significantly reduce the overall company productivity and lead to job loss.
This thing really happened to me. So, I suggest those who have been facing their computers for a long time just gambling their way, might want to back off a little and think about what is happening with their life. It could totally ruin your productivity as an employee and that might get you jobless in the future. I've seen it and it happened to me. Thankfully, my supervisor was good to me and I had a good record as an employee before.
I am not a gambling addict yet, I could tell, but sometimes you will get hooked with the game especially if you are chasing your losses.
health Challenges: A gambling addict is always under pressure and tension and as such is prone to health challenges like high blood pressure, depression, and on the part of his people, they might be suffering from the psychological implications of his lifestyle which includes social stigma.
Stress can really have many implications for our bodies. When I was chasing losses and for two days trying to get it back with lack of sleep, I felt a lot of body pain and my acid was way high because of it. When I stopped doing it, everything was gone with just one good night's sleep. Truly, gambling can affect us if we are in the event where we badly want our money back. It's better if we can accept that the money is gone so that we won't have the drive to keep on chasing it.
That's only the first part that it will affect our body, the rest is what OP said if we keep on going and get addicted with it.
