Differentiating T1D from type 2 diabetes is cucial. Autoantibody testing (GADA, IA- 2A, IAA, ZnT8A) and measurement of C- peptide (a marker of endogenous insulin production) are used te to confirm autoimmunology. Low C- peptide levels indicate seree insulin defidency.

Aktywność fizjologiczna

Regular exercise improwises insulin sensitivity, cardiovascular health, and psychological well-being. However, it requires careful glucose monitoring and insulin adjustment to prevent exercise- inducted hypoglycemia or, less common, hyperglycemia.

Monitoring

Self-monitoring of blood glucose (SMBG) using fingerstick meters readings entis essential. Increasingy, continuous glucose monitoring (CGM) systems such as Dexcom or Libre provide real-time glucose readings and trend information, enabling more proactive management.
