If gambler gambles excessively to win or gambles to earn money, it is very natural for him to have high blood pressure. Gambling is never suggested for the purpose of earning money. But some gamblers lose control over themselves due to their greed. At some point, they also become addicted gamblers. If gambling is accepted as fun, then even if the gambler loses, he will never be depressed or upset if he loses the bet. In most cases, gamblers bet with the money they cannot afford to lose, which is why they cannot accept defeat or have to face health problems after losing their bets.
Only when you are suffering series of losses that you actually get to suffer such but I believe if you are actually having streaks of wins you may likely not have the issues with your BP you will rather be too excited and want to play some more because you can only want more when you see that you are already getting from the game. The fun is mostly in the winnings while the thrill actually come in the loses, a few times tough.
