Type 1 diabetes and Ramadan complications
Assessment of the IDF-DAR Fasting Risk Assessment Tool to Predict Type 1 Diabetes-Related Complications During Ramadan in a Real-World Setting.
Overview
Alguwaihes AM et al.. Clin Med Insights Endocrinol Diabetes 2025 · PMID 41001082 · DOI 10.1177/11795514251376888
Among 963 Saudi adults with type 1 diabetes, those rated high risk had more complications and emergency visits when fasting.
Does the study support the specific claim? No · Methodological quality: low
Plain-language summary
Study explained simply
- What did the researchers want to find out?
Test a fasting risk tool.
- How was the study done?
Online survey after Ramadan 2022.
- How many people, animals or samples were studied?
963 adults with T1D.
- What was actually found?
High-risk group: more ER visits; education linked to fewer visits.
- How large was the observed effect?
OR 0.53 (0.34-0.82) for education.
- What do the results mean in everyday life?
Fasting with type 1 diabetes can lead to emergencies; preparation with doctors helps.
- What are the study's limitations?
Self-reported; no lab confirmation.
- What does it say about Elawady's specific claim?
Contradicts the idea that high sugar during fasting is harmless.
- Do the results apply to Germany and Europe?
Directly relevant to Arab populations including Egypt.
- What can explicitly not be concluded from this study?
Exact DKA rates.

2. Research question
Does the IDF-DAR 2021 risk calculator predict complications in adults with type 1 diabetes fasting Ramadan?
3. Study design and population
- Study design
- Cross-sectional study – Cross-sectional online survey
- Population
Adults with type 1 diabetes in Saudi Arabia who observed Ramadan 2022
- Country
Saudi Arabia
- Period
May-August 2022
- Sample size
963 (257 men, 706 women; mean age 26.5)
- Inclusion and exclusion criteria
not stated in abstract
4. Methods and endpoints
- Exposure / intervention
IDF-DAR risk category; pre-Ramadan education
- Comparator
Moderate-risk group; no education
- Endpoints
Days fast broken, complications, diabetes-related ER visits
- Statistical methods
Group comparisons; odds ratios
5. Actual results
- Results
66% high risk, 34% moderate risk, none low risk. High-risk group: more days with broken fast, more complications, more diabetes-related ER visits (P<.01). Pre-Ramadan education associated with lower odds of ER visit (OR 0.53, 95% CI 0.34-0.82).
- Absolute risks
not reported
- Authors' conclusion
The IDF-DAR risk calculator predicts acute complications and ER visits; pre-Ramadan education may reduce complications.
6. Strengths
- Large regional sample
- Real-world setting relevant to Arab countries
7. Weaknesses
- Self-reported online survey; recall and selection bias
- No objective confirmation of DKA
8. Risk of bias
- Orienting tool
- ROBINS-E
- Type of assessment
- simplified assessment (abstract only)
- Full formal assessment
- no
- Overall risk of bias
- high
- Rationale
Self-report, self-selection, confounding of education effect.
9. Assessment of the statistical interpretation
OR 0.53 is an odds ratio from cross-sectional data, not a causal risk reduction (stats/I-FAST-109_idf_dar_tool.py).
10. Relevance to the specific claim
Shows fasting with type 1 diabetes leads to emergency visits in a regional population, especially in high-risk individuals.
11. Independent contrary findings
12. Transferability to Germany and Europe
Universal biology; applies in Europe and Egypt.
13. Overall methodological judgement
Regional evidence that fasting with T1D carries real acute risk requiring assessment and education.

14. Open questions
15. Linked fact checks
- Rising blood glucose and acetone (ketones) during fasting are evidence that the liver is working properly, not a danger; high glucose plus acetone is not insulin deficiency. – Studies contradicting or limiting the claim
