Study Notes
Diabetes Management and Insulin Delivery Methods
- The dawn phenomenon involves a rise in blood glucose levels around 3 AM due to nocturnal surges in growth hormone secretion, creating a greater need for insulin in the early morning hours in patients with type 1 diabetes.
- It must be distinguished from insulin waning and the Somogyi effect, which are different causes of morning hyperglycemia.
- Insulin delivery methods include traditional subcutaneous injections, insulin pens, jet injectors, and insulin pumps, each with specific advantages and considerations.
- Insulin pens use prefilled insulin cartridges and are convenient for patients who need to inject only one type of insulin at a time or who have impaired manual dexterity, vision, or cognitive function.
- Jet injectors deliver insulin through the skin under pressure and may have different absorption rates, peak insulin activity, and insulin levels compared to traditional injections.
- Insulin pumps provide continuous subcutaneous insulin infusion, mimicking the functions of a healthy pancreas by adjusting insulin delivery based on basal insulin every 5 minutes.
- Insulin pumps offer flexibility in meal timing and content, but there are potential disadvantages such as disruptions in insulin flow, infection at insertion sites, and increased risk of hypoglycemia unawareness.
- Candidates for insulin pumps must be willing to assess their blood glucose levels several times daily and have extensive education in self-management of blood glucose and insulin doses.
- Insulin pumps can be disconnected for limited periods, such as for showering, exercise, swimming, or sexual activity, and require psychological stability and comfort with diabetes.
- Effective education is crucial to minimize the risk of disruptions in insulin flow and hypoglycemia.
- Insulin pump users must work closely with a healthcare provider and be willing to have a visible sign of diabetes, serving as a constant reminder of their condition.
- Overall, the choice of insulin delivery method should consider patient preferences, lifestyle, and the need for effective diabetes management.
