Nutrition D.6 Flashcards
6.1. Describe the acute effects of excess alcohol on the hydration and kidney function
- Vomiting
- Dehydration
- Increased Urination
6.2.Outline the possible effects of excessive chronic alcohol intake on liver
- Liver cancer
- Fatty liver disease
- Alcoholic hepatitis
- Fibrosis
- Cirrhosis
6.2.Outline the possible effects of excessive chronic alcohol intake on heart
- Increase BP, irregular HR
- Decrease left ventricular function
- Blood clots
- Stroke
- Cardiomyopathy
- Heart attack
6.2.Outline the possible effects of excessive chronic alcohol intake on kidney
- Impairment in ability to regulate volume and composition of fluid and electrolytes in the body
- May experience low concentrations of electrolytes and potentially severe alterations in body’s acid-base balance
- Disrupt hormonal control mechanisms that govern kidney function
- High blood pressure
- Damage to liver = more work for kidneys = damaging the kidneys
6.2. Outline the possible effects of excessive chronic alcohol intake on brain
- Thiamine, or vitamin B1 deficiency = can lead to Wernicke-Korsakoff syndrome
- Confusion, impaired coordination, learning problems and memory difficulties
- Can harm brain, symptoms such as sleep changes, alterations in mood, personality changes, depression, anxiety, impaired concentration
- May hinder new brain cell growth
6.3. Discuss the effects of alcohol on athletic performance
Ergogenic Effects:
- Anti-tremor
- Low amounts of alcohol (0.02-0.05 g/dL) might assist in sports such as shooting and archery by reducing hand tremors, but levels above this will have a negative impact
Ergolytic Effects:
- Balance
- Power and strength
- Endurance
- Speed
- Coordination
- Reaction time and cognitive processing
- Cardiac functioning
- Inhibition of gluconeogenesis
Any amount of alcohol is likely to impair performance in activities such as running and power sports
6.1. Describe the acute effects of excess alcohol on the cardiovascular system
- Dilation of blood vessels, causing a feeling of warmth but resulting in rapid loss of body heat
- Raised blood pressure
- Passing out
6.1. Describe the acute effects of excess alcohol on thermoregulation
Reduced core body temperature
6.1. Describe the acute effects of excess alcohol on the neurologic systems
- Lowered inhibitions, leading to poor social judgment
- Trouble concentrating
- Loss of coordination
- Loss of critical judgment
- Dulled perception, especially vision
- Mood swings
