Hangovers can have various causes, ranging in severity from 'very minor' to 'needs attention'. Finding the true cause means ruling out or confirming each possibility – in other words, diagnosis.
Diagnosis is usually a complex process due to the sheer number of possible causes and related symptoms. In order to diagnose hangovers, we could:
|Magnesium Need||2%||Ruled out|
|Lack Of Sleep||1%||Ruled out|
|Vitamin B1 Need||1%||Ruled out|
When you get hangovers from drinking alcohol, how severe are they generally?
Possible responses:→ Not applicable / don't know
→ Very mild - almost nothing
→ Usually mild, sometimes quite bad
→ Usually quite bad, sometimes awful
→ Awful - I'm a complete wreck
Lack of sleep increases susceptibility to hangovers.
Acetaldehyde is a toxic substance produced in the body from alcohol and is one of the impurities found in cheap wine and 'moonshine' spirits. Some researchers believe that an acetaldehyde buildup is the cause of hangovers. If the liver's detoxification pathways are impaired, aldehydes can, instead of being converted to the next intermediate product, build up to harmful levels and cause damage since they are often more toxic than the original substances from which they are derived.
It is probably the metabolism of methanol to formaldehyde and formic acid that causes hangover symptoms. Quick methanol metabolizers suffer more. This is reinforced by the fact that the types of drinks associated with more severe hangovers contain higher levels of methanol. [Hangovers: Not The Ethanol, Perhaps The Methanol, British Medical Journal, January 4, 1997;14: pp.2-3]
All types of alcoholic drinks contain some methanol, a substance blamed for the worst hangovers. Whiskey, cheap red wine, fruit brandy and other dark spirits contain the most methanol, sometimes as much as 2% by volume. Vodka and other clear drinks contain the least. In the liver, methanol takes 10 times longer than ethanol to break down.
It is possible that some of the hangover symptoms related to alcohol are in part due to magnesium depletion.
A deficiency in thiamine (vitamin B1) makes it harder for your body to break down alcohol. Interestingly, beer contains a good amount of thiamine, but as vitamin B1 oxidizes the alcohol out of the blood in the liver, thiamine is used up and must be replaced.
