SUMMARY 1. Dopamine‐β‐hydroxylase (DβH) activity was measured in sera from ten healthy male students after 2 and 3 days fasting which is associated with increased circulating noradrenaline. 2. Circulating DβH remained essentially unchanged throughout the fasting period, although ‘stress parameters’ like plasma glycerol and free fatty acid concentrations were elevated by a factor of about two from first to second and third day of fasting ( P <.0.01). 3. Serum DβH activity is not a sensitive index of increased sympathoadrenal activity in fasting man.
