The most important updates are the definition of hypoglycemia, the dosing of intranasal glucagon (Baqsimi), and reviewing the evidence on hypoglycemia with the newer insulins (which will become out of date again once insulin Icodec (the once weekly insulin) comes out in fall of 2024).

Under the heading of: Definition and Frequency of Hypoglycemia

Remember that the class of hypoglycemia is not defined by the blood glucose level but by symptoms and if the patient can help themselves or not. Know Table 1.

Please see the original chapter 14 for a review of the autonomic and neuroglycopenic symptoms start

Memorize Table 2

Know that effects the hypoglycemia can cause on the cardiovascular system, fall risk, a person’s quality of life, and the fear hypoglycemia can cause.

There are now scales that you can use to measure a person’s fear of hypoglycemia. Please see below.

For more details on the The Hypoglycemia Fear Scale version 2 (HFS-II) please: see https://professional.diabetes.org/sites/default/files/media/ada_mental_health_workbook_chapter_4.pdf

Under the heading of: Prevention 

Know which insulins and oral anti-hyperglycemics that have a lower risk of hypoglycemia

Know that structured psychoeducation programs such as HypoCOMPaSS (https://diabetesjournals.org/care/article/37/8/2114/29774/Recovery-of-Hypoglycemia-Awareness-in-Long) can reduce the prevalence of hypoglycemia

Know the interventions to prevent exercise induced hypoglycemia.

Under the heading of: Treatment

Know the amounts of carbohydrates, the does of IM/SC glucagon, and the dose of IN glucagon used to treat hypoglycemia. Memorize Table 4. Know what can interfere with glucagon.

D) The sympathoadrenal response to hypoglycemia is increased due to sleep due to the dawn phenomenon

 

Which of the following insulins is associated with the lowest risk of hypoglycemia?
