Abstract
Pain threshold was measured with short heat stimuli using a contact thermode in 19 patients with anorexia nervosa, 20 patients with bulimia nervosa, and 21 control subjects. Both patient groups had significantly elevated pain thresholds compared with the control subjects. In the total sample, no substantial covariation could be demonstrated among pain threshold and clinical, physiological, metabolic, or psychological data. However, in separate regression analyses pain threshold correlated significantly (negatively) with local skin temperature in the anorectic patients and almost significantly (positively) with body weight in the bulimic patients. This finding suggests that the reduced pain sensitivity in the two kinds of eating disorders might have different causes.

158 Citations1985Karl M. Pirke, Jörg Pahl +2 more
Data indicate that many patients with bulimia showed the metabolic signs of starvation at the time of the study, a finding supported by the symptoms of endocrine adaptation to starvation, namely low triiodothyronine and a decreased noradrenaline response to an orthostatic test in many of these patients.

The difference in pain sensitivities supports the hypothesis that the weight difference between the obese and nonobese subjects may be related to endogenous opiate control of ingestive behaviors.
PainSensitivity to cold pressor pain in dysmenorrheic and non-dysmenorrheic women as a function of menstrual cycle phase
108 Citations1988Eleni G. Hapidou, Denys de Catanzaro
A significantly lower pain threshold was obtained during the luteal as compared to the follicular phase of the menstrual cycle, and this finding may support an adaptation‐levels model, in that dysmenorrheic women report less pain than do non‐dysmenorrhic women because they compare cold pressor pain with internal menstrual pain.

Data suggest diminished endogenous opioid system activity in some schizophrenics, and a relationship between opioid activity and state change in manic-depressive illness and anorexia nervosa is consistent with basic science and clinical data suggesting interactions between CNS noradrenergic and opioid systems.

The spinal cord is probably much more important than hitherto believed for integration and in determining the characteristic discharge patterns of the sympathetic pre- and post-ganglionic neurones, which are described as a general reaction to noxious stimuli.

Naloxone did not differ from placebo in its effect on the pain thresholds (phasic and tonic), suggesting that a nonopioid mechanism was responsible for the threshold elevation found in the eating disorder patients.

There is a significant reverse correlation between degree of overweight and the threshold of the nociceptive reflex, and the hypothesis of an abnormality of the endogenous morphine-like system or of their control in human obesity is suggested.

In rats anaesthetised with Saffan, selective excitation of neurones in the ventrolateral medulla in the region of nucleus paragigantocellularis lateralis by microinjection of the synaptic excitant, d,l‐homocysteic acid, produced an increase in the latency of the tail flick response to noxious heat usually accompanied by a increase in blood pressure and heart rate.

It is hypothesized that such an elevation of beta-endorphin is the result of stress and that it may play an important role in the perpetuation of the binge-vomiting cycle.

The hypothesis of the existence of a modulation of heat pain by body as well as by mean skin temperature is tested and it is reported here that the temperatures at which heat pain starts and at which it becomes intolerable are independent of mean skin and body temperatures.

It is suggested that an elevation in the set-point temperature for behavioural thermoregulation can occur in some patients with anorexia nervosa, and that this displacement may contribute to the distressing sense of cold which some patient experience.
