It is not uncommon for alcoholism to run in families, like lots of other traits. Studies have shown that there is a bit of a genetic component when it comes to addiction. Hereditary connections do exist when it comes to this problem though we don’t have a ton of information on it yet.
Alcoholism is a chronic disease that can cause much different health and mental problems if left untreated. It can even lead to an early death. If addiction is caught early on and prevented then most of the problems it causes can be reversed. This isn’t the case if it continues for many years.
