Adolescence is a time of rapid change – not only emotionally and socially, but physically too. Growth spurts, changing hormones, and increased activity levels all affect blood glucose management. For young people living with type 1 diabetes, these changes can increase the risk of hypoglycaemia (hypos).
Why Growth Matters
During adolescence, the body needs more energy to support growth. Insulin requirements can fluctuate day-to-day, sometimes even hour-to-hour. Factors such as puberty hormones, increased appetite, and changes in sleep patterns can all impact blood glucose levels.
Common Triggers for Hypos in Adolescents
- Growth Spurts: Periods of rapid growth can increase insulin sensitivity, leading to unexpected lows.
- Physical Activity: Sports, walking to school, or even spontaneous activity with friends can burn through glucose quickly.
- Hormonal Shifts: Puberty hormones (like growth hormone and sex hormones) can cause swings in insulin sensitivity – sometimes high, sometimes low.
- Irregular Eating Patterns: Skipped meals, later breakfasts, or grazing can make it harder to match insulin with food intake.
Risks of Repeated Hypos
While an occasional hypo is part of life with type 1 diabetes, frequent or severe hypos can affect:
- School performance and concentration – low glucose levels can impair memory and focus.
- Confidence and independence – fear of hypos may cause teens (and parents) to avoid activities.
- Safety – overnight hypos or exercise-related lows can be particularly dangerous if unnoticed.
Tips to Reduce Hypo Risk
- Regular Monitoring: Using a continuous glucose monitor (CGM) or finger-prick checks helps detect patterns and prevent surprises.
- Snack Planning: Extra carbs may be needed before or after sport, especially in the evening.
- Adjusting Insulin: Growth phases often require fine-tuning of insulin doses – always with guidance from the diabetes team.
- Education and Support: Encourage teens to recognise their own hypo warning signs and carry fast and long-acting carbs everywhere.
Adolescence is already a balancing act, and managing type 1 diabetes adds another layer. With awareness, education, and the right support, young people can grow, thrive, and keep hypos under control.
