有一天喝了两瓶,结果晕不说,特别难受,想吐,又吐不出来,坐在浴室的地上靠着浴缸,一下短暂地失去了意识,没了知觉,后来醒了后一头一身虚汗,想起来很后怕。以后吸取教训,绝对不能多喝酒。
Passing out from alcohol means that the person loses consciousness.
It could look like someone who suddenly loses consciousness after drinking.
Alcohol use leading to passing out could also
lead to breathing less than 8 times per minute, uncontrollable vomiting, bluish or pale skin, confusion, seizures, or uneven breathing.
Suspected Causes
Alcohol lowers blood pressure. If someone is sober, their body constricts their veins upon standing up so as to increase blood pressure and prevent the person from passing out as their blood falls due to gravity. Even with low-risk drinking (2-3 drinks per occasion), alcohol prevents the blood vessels from constricting, and
blood pressure drops twice as much when the person stands up as it would if they were sober.
Alcohol is a diuretic, and
causes your body to dehydrate.
Alcohol also lowers your body temperature, and can cause you to become hypothermic.
Alcohol can also
cause hypoglycemia, which can cause a coma.
Associated Dangers
Taking a cold shower, which is an ineffective technique often used to “sober up,” can actually cause a person with alcohol poisoning to
lose consciousness due to the decrease in body temperature.
Alcohol also inhibits the gag reflex, which can cause a person who
is unconscious to aspirate their own vomit, causing death.
Drinking enough alcohol to reach the point of passing out can happen very quickly, especially when drinking shots. This means that a person can drink enough to cause them to pass out, but not pass out for a while longer (and therefore, possibly continue to drink) due to the time the body needs to process alcohol.
Drinking to the point of
passing out happens much faster when the person has not eaten. On an empty stomach, 20% of alcohol is absorbed directly from the stomach and reaches the brain in less than 60 seconds.
