RESUMO
Insulin therapy is the cornerstone of diabetes management in people with type 2 diabetes mellitus (T2DM). Therefore, its use is recommended even in special populations and situations such as the elderly, pregnant women, obese individuals, people observing religious fasting, and in the presence of comorbidities such as renal insufficiency, and cancer. Since these special situations predispose to complications such as a high risk of hypoglycemia, patients need constant glucose monitoring and insulin dose adjustments, wherever applicable. This review discusses the various considerations that might guide the decision-making process in the special situations alluded to here. It also throws light on how insulin glargine 100 U/mL has emerged as a preferred choice of insulin therapy in most of these situations, on the strength of its inherently low hypoglycemia and weight gain potential, which has found traction even in the recent diabetes guidelines.
