Summary

Hypoglycaemia negatively impacts mood in patients with insulin-dependent diabetes mellitus (IDDM). High hostility scores correlate with increased anger during low blood sugar events.

Area of Science:

  • Endocrinology
  • Psychology
  • Clinical Medicine

Background:

  • Hypoglycaemia is a common complication of insulin-dependent diabetes mellitus (IDDM).
  • The psychological effects of hypoglycaemia, particularly mood disturbances, require further investigation.
  • Understanding the interplay between psychological traits and emotional responses during hypoglycaemia is crucial for patient management.

Purpose of the Study:

  • To investigate the effects of induced hypoglycaemia on mood states in IDDM patients.
  • To determine if psychological characteristics mediate emotional disturbances during hypoglycaemia.
  • To explore the relationship between hostility and anger responses during hypoglycaemic episodes.

Main Methods:

  • A standardized stepwise hypoglycaemic, hyperinsulinaemic clamp was used to induce controlled low blood glucose levels in ten IDDM patients.

  • Patients underwent mood assessments using the Profile of Mood States (POMS) and the COOP/WONCA feelings chart at various glucose levels.
  • Psychological characteristics were evaluated using the Symptom Checklist-90 (SCL-90) at euglycaemic (normal blood sugar) conditions.

    • Main Results:

    • A significant increase in anger (POMS) was observed as blood glucose levels decreased (P < 0.05).
    • Mood progressively worsened with each step of induced hypoglycaemia, showing significant interindividual variability.
    • A significant interaction was found between high hostility scores (SCL-90) and increased anger (POMS) at a glucose level of 2.5 mmol/l (P < 0.05).

    Conclusions:

    • Progressive hypoglycaemia leads to a negative alteration in the overall mood state of IDDM patients.
    • IDDM patients with higher hostility scores are more susceptible to experiencing increased anger during hypoglycaemic events.
    • Psychological factors, such as hostility, play a role in mediating emotional responses to hypoglycaemia in diabetes management.
