When an individual is drunk, his body lacks coordination, which affects gait. He is unable to think clearly when drunk and may suffer a suppressed immune system due to excessive alcohol consumption in the long-term, says Healthline.
Drunkenness affects behavior, as alcohol quickly reaches the brain and affects the central nervous system. Drunkenness leads to slurred speech and impairs coordination, causing the individual to lack balance when he walks. Excessive drinking affects the ability to think clearly, and the individual may have difficulty controlling his impulses or forming memories, explains Healthline. In some cases, alcoholism can cause a deficiency of vitamin B-1, causing involuntary and rapid eye movements and weakness.
An incidence of heavy drinking may injure part of the digestive tract, causing gassiness, vomiting and diarrhea. It may also cause ulceration, acid reflux or heartburn, according to Healthline. When an individual is drunk, the body’s ability to absorb nutrients such as thiamine, folic acid and vitamin B-12 diminishes, meaning he may face malnutrition. Diabetics are at high risk of low blood pressure and a low blood count when they drink.
Long-term drunkenness may cause muscle cramps, atrophy or raise the risk of osteoporosis, as the body’s ability to produce new bones diminishes. Individuals also become more prone to illnesses such as pneumonia due to a weakened immune system resulting from alcohol abuse, states Healthline.
