Evaluation & tests
Educational note: clinicians diagnose diabetes using blood-glucose tests such as fasting glucose or HbA1c. This library does not diagnose.
Treatment education
Educational overview: care is individualized and may combine education, nutrition, activity, glucose monitoring, and clinician-prescribed medicines. This library does not prescribe.
Self-care
General education: understanding blood-sugar patterns, healthy eating, activity, and attending reviews support day-to-day diabetes health.
When to seek care
Discuss diabetes concerns with a qualified clinician; seek urgent care for confusion, severe vomiting, difficulty breathing, or very high or very low blood-sugar symptoms.
