Alcohol can have a very negative impact on your stomach and is very dangerous. It becomes very hard for your body to create natural digestive fluids as well as failing to absorb food which it can't even digest properly. Alcoholics usually go through periods of nausea, distention or prostration. You are prone to want to drink more when you are in this condition as well as want to eat more. You can also face dyspepsia which is a permanent drinking disorder. If you find that you consume alcohol regularly and can't stop you should seriously pursue getting help.
Alcohol can be fatal and cause organic deterioration if you choose to keep using it over a long period of time. The liver is the organ that commonly gets damaged by continuous use of alcohol. This is because the liver usually can hold active substances inside of it. So all poisons your system brings in are filtered out through the liver. And too much of anything, including alcohol, will tend to destroy this organ over time. So if you are an alcoholic you can expect to have a liver that is saturated with alcohol, so this is something to think about if you choose to continue drinking.
Once your liver gets damaged, it will prevent proper dialysis as well as free secretion. This means you may need dialysis treatments later if you don't quit now. Ask anyone who is on dialysis and they'll tell you how horrible these treatments are. They can be painful, cause you to get very sick and drastically shorten your life. Alcohol abuse can also cause your liver to become large because of vessel dilatation. The liver structure can be charged with fat cells and you can experience what is commonly called "fatty liver".
When you consume too much alcohol your kidneys can suffer as well. Your kidney vells will eventually lose elasticity and flexibility. Alcohol also tends to relax your lung vessels while they are exposed to hot and cold variations. When your body experiences a rapid change in temperature, your vessels can get very congested. If you are in the middle of a very cold winter season, you could experience a fatal congestion. Alcohol also severely effects the heart. The membrane structures around it become thicker, the the valves become less supple and you can end up with valvular disorder which is a permanent condition.
