Short-term effects of alcohol on human body
Brain: Alcohol slows down the chemicals and pathways your brain uses to control your body, altering mood, slowing down reflexes and affecting balance. It also can contribute to learning, memory, and sleep problems.
Heart: Alcohol increases your heart rate and expands your blood vessels, making more blood flow to the skin (which causes you to feel warm), however, this heat passes out through the skin, causing body temperature to fall after it has risen.
Digestive: Alcohol is first broken down in the stomach, promoting an increase in digestive juices. Alcohol also irritates the small intestine and colon where it is further broken down and absorbed, and it also can affect the normal speed that food moves through them, which may result in abdominal pain, bloating, and diarrhea.
Kidney: Alcohol dries out (i.e., dehydrates) the body, which can affect the kidneys and the body’s ability to regulate fluid and electrolytes. It also disrupts hormones that affect kidney function.
Liver: Alcohol—most of it, in fact—is metabolized in the liver, which filters circulating blood and removes and destroys toxic substances, including alcohol. The liver can handle a certain amount of alcohol, but as a person continues to drink, it can become stressed to the point of causing permanent damage.
