Male Sprague-Dawley rats were uninephrectomized and given either deoxycorticosterone (DOC) pivalate (12.5 mg three times weekly) and 1% NaCl/0.2% KCl to drink for 4 weeks (DOC-treated), after which DOC was stopped and tap water substituted (post-DOC), or tap water to drink throughout (controls), DOC treatment increased blood pressure, serum sodium, plasma atrial natriuretic peptide (P-ANP) and plasma deoxycorticosterone (P-DOC) (P less than 0.05), while serum potassium, plasma renin and plasma angiotensin II were lower (P less than 0.05) than in control animals. Plasma vasopressin (P-AVP) was also raised but not significantly. These changes persisted for up to 4 weeks post-DOC and, in the case of plasma renin, plasma angiotensin II, P-AVP and P-ANP, for up to 12 weeks. Total body sodium was also increased at 2 weeks post-DOC (P less than 0.05). Rats which were adrenalectomized after 4 weeks of DOC treatment in which DOC injections were stopped, then drank either NaCl/KCl or tap water; blood pressure and P-DOC remained elevated while plasma renin remained suppressed. There were more deaths in rats given NaCl/KCl (five of six) than in the group given water (one of six). Rats treated with a subcutaneous DOC silastic implant had a comparable rise in blood pressure to rats given DOC injections. However, after removal of the implant, while blood pressure remained elevated, P-DOC levels were not raised and plasma renin rose to control levels after 4 weeks. These findings indicate that, in rats given DOC injections, post-DOC hypertension results from sodium and fluid retention as a consequence of chronic hangover of exogenously administered DOC.

The consequences of drinking six pints of beer (3.31) over three hours were investigated in six healthy men. The expected rise in plasma osmolality, fall in plasma vasopressin concentration, and increase in free water clearance occurred; these variables had returned to normal by nine hours. There was a small but significant fall in plasma concentrations of urea and creatinine accompanied by a rise in plasma potassium concentration. Serum activities of alkaline phosphatase, gamma-glutamyl transferase, creatinine kinase, and lactate dehydrogenase did not change, and there was no alcohol-induced hypoglycaemia. All subjects had a slight hangover, but none was fluid depleted. It is concluded that, apart from inducing changes in water balance, alcohol in this form causes remarkably little metabolic disturbance.

Research on human subjects analyzing blood and urine samples determined biological correlates that may explain the pathology of alcohol hangover. These analyses showed that concentrations of various hormones, electrolytes, free fatty acids, triglycerides, lactate, ketone bodies, cortisol, and glucose were not significantly correlated with reported alcohol hangover severity. Also, markers of dehydration (e.g., vasopressin) were not significantly related to hangover severity. Some studies report a significant correlation between blood acetaldehyde concentration and hangover severity, but most convincing is the significant relationship between immune factors and hangover severity. The latter is supported by studies showing that hangover severity may be reduced by inhibitors of prostaglandin synthesis. Several factors do not cause alcohol hangover but can aggravate its severity. These include sleep deprivation, smoking, congeners, health status, genetics and individual differences. Future studies should more rigorously study these factors as well as biological correlates to further elucidate the pathology of alcohol hangover.
