Headaches caused by alcohol consumption are felt as pulsating, throbbing or pounding and are caused by various factors. Excessive drinking leads to intoxication and a hangover the next day. Excessive amounts of fusel alcohols and acetaldehyde in wine also favour this. Other causes are excessive loss of fluids and minerals. Alcohol causes the body to become severely dehydrated.
Under certain circumstances, more fluid is excreted than the amount drunk. Important minerals such as magnesium are lost in the process. Even low alcohol consumption can cause headaches or migraines in allergy sufferers due to the histamine, quercetin and tyramine present in red wine in particular.
