In the body, ethanol primarily affects the central nervous system, acting as a depressant and causing sedation, relaxation, and decreased anxiety. The complete list of mechanisms remains an area of research, but ethanol has been shown to affect ligand-gated ion channels, particularly the GABA A receptor .
Alcohol affects males and females differently because of difference in body fat percentage and water content. On average, for equal body weight, women have a higher body fat percentage than men. Since alcohol is absorbed into body water content, and men have more water in their bodies than women, for women there will be a higher blood alcohol ...

Alcohol is known to potentiate the insulin response of the human body to glucose, which, in essence, "instructs" the body to convert consumed carbohydrates into fat and to suppress carbohydrate and fat oxidation. [63] [64] Ethanol is directly processed in the liver to acetyl CoA, the same intermediate product as in glucose metabolism.
Longer timeframes for drinking alcohol can lead to higher consumption and blood alcohol levels, Dr. Issac explains. So, you don't just feel drunker after a day of drinking—you are drunker. 2.
Direct alcohol tolerance is largely dependent on body size. Large-bodied people will require more alcohol to reach insobriety than lightly built people. [4] The alcohol tolerance is also connected with activity of alcohol dehydrogenases (a group of enzymes responsible for the breakdown of alcohol) in the liver, and in the bloodstream.
Alcohol-related brain damage [1] [2] alters both the structure and function of the brain as a result of the direct neurotoxic effects of alcohol intoxication or acute alcohol withdrawal. Increased alcohol intake is associated with damage to brain regions including the frontal lobe , [ 3 ] limbic system , and cerebellum , [ 4 ] with widespread ...
Alcohol affects the nutritional state of chronic drinkers. It can decrease food consumption and lead to malabsorption. It can also create imbalances in skeletal muscle mass and cause muscle wasting. Chronic consumption of alcohol can also increase the breakdown of important proteins in the body which can affect gene expression. [161]
