Recent psychoanalytically inspired psychosomatics conceptualises somatic di
sorders as disorders in the internalised relationship with a regulating obj
ect, causing physiological/affective dysregulation. In diabetes mellitus, m
easurements of blood glucose allow close monitoring of a form of somatic re
gulation. Several authors have reported parallels between glycaemic oscilla
tions and relational vicissitudes, in both experimental and clinical settin
gs. Mothers of diabetic patients report a history of misattunement in feedi
ng patterns, while similar difficulties, on the symbolic level of accepting
mutual communication, are found in the analysis of adult patients. More or
less conscious opposition to glycaemic regulation appears to be linked wit
h problems in distance regulation with the object. The author reports a cli
nical case that gives evidence of this parallelism; the patient presents a
marked nonintegration and dysregulation of relational and separateness need
s, which both emerge, with respect to the analyst and to other objects, in
a quickly alternating, violent, juxtaposed fashion reminiscent of descripti
ons of disorganised attachment or of borderline patients. These oscillation
s are closely paralleled by oscillations in glycaemic control where violent
withdrawal from relationships corresponds to physiological and behavioural
disruption of glycaemic regulation patterns Improved mentalisation and int
egration of the different tendencies in the course of analysis brings to bo
th the possibility of stable affective involvement and improvement in diabe
tic control.
