Diabulimia is a commonly used term for insulin restriction or omission linked with weight or body-shape concerns in someone with type 1 diabetes. Many professionals now use terms such as type 1 diabetes with disordered eating.
Quick summary
This is not a lack of willpower. It is a serious eating disorder and diabetes safety issue. People with type 1 diabetes need insulin to live, and insulin omission can lead to diabetic ketoacidosis, hospital admission, long-term complications, and death.
Key takeaways
- Insulin omission for weight loss is medically urgent.
- The person needs support, not blame.
- Treatment should involve both diabetes and eating-disorder expertise.
- Family, clinicians, and friends should avoid shame and focus on safety and care.
Warning signs
- Skipping or reducing insulin because of weight fears.
- Repeated very high glucose or ketones.
- Avoiding appointments, glucose checks, or downloads.
- Strong fear of weight gain from insulin.
- Frequent DKA, secrecy around insulin, or intense distress about food and body shape.
What support can look like
Recovery usually needs coordinated care. That may include an endocrinology team, eating-disorder therapist, dietitian, diabetes educator, and sometimes higher-level mental health or medical care.
If insulin is being rationed because of cost, supply problems, or fear of access, that is also urgent. Tell a clinician, pharmacist, or emergency service. The solution should be insulin access and safety, not shame.
Practical takeaway
