Alcohol and Health

Short-Term Health Effects of Alcohol

Alcohol is a depressant that affects all body systems and organs. Its effects can range from mild impairment to organ damage or even death. Short-term effects of alcohol include impaired judgment, motor skills, and risk of poisoning.

CNS Depression

GI System Irritation

  • Dulled senses, impaired memory

  • Sudden loss of self-control

  • Nausea and vomiting

  • Stomach irritation

Cardiovascular Health

Accidents/Injuries

  • Heart rate and pumping less efficient

  • Impaired motor skills

  • Increased risk of falls, burns, and other injuries

Risky Sexual Behavior

Alcohol Poisoning

  • Impaired sexual decision-making

  • Confusion, slowed speech, vomiting, and unconsciousness

  • Example: Deep unconsciousness for a prolonged period is a symptom of alcohol poisoning.

Long-Term Health Effects of Alcohol

Long-term use of alcohol damages tissues/organs and increases risk of chronic diseases.

Weight Gain

Cardiovascular Health

  • 1 drink contains ~150 kcal

  • Excess calories lead to obesity

  • Weakening of heart muscle

  • Increased risk of stroke

Damage to the Brain

Liver Disease

  • Memory loss, cognitive decline

  • Impaired coordination

  • Fatty liver, hepatitis, cirrhosis

Cancer

Fetal Abnormalities

  • Increased risk of mouth, throat, liver, and breast cancer

  • Alcohol use during pregnancy can cause teratogenesis (birth defects)

  • Example: Jaundice (yellowing of the skin and eyes) is a sign of liver damage, often due to chronic alcohol use.

Alcohol Poisoning and Symptoms

Alcohol poisoning is a serious and potentially fatal condition resulting from consuming large amounts of alcohol in a short period. Symptoms include:

  • Vomiting

  • Deep unconsciousness

  • Slowed or irregular breathing

  • Confusion and inability to respond

Comparing Short-Term and Long-Term Effects

  • Short-term effects are immediate and include impaired judgment, nausea, and risk of accidents.

  • Long-term effects develop over time and include organ damage, increased risk of chronic diseases, and cancer.

Key Terms

  • Alcohol Poisoning: A dangerous condition caused by consuming excessive alcohol, leading to life-threatening symptoms.

  • Cirrhosis: Chronic liver damage from long-term alcohol use, resulting in scarring and liver failure.

  • Teratogenesis: The process by which birth defects are produced in an embryo or fetus.

Relevant Equations

Additional info:

  • Alcohol is classified as a central nervous system depressant, meaning it slows down brain activity and bodily functions.

  • Chronic alcohol use is a major risk factor for non-communicable diseases such as cardiovascular disease and cancer.
