Q

When is there a rapid rise in plasma insulin, what is the purpose?

A

Following a meal there is a rapid rise in plasma insulin to limit postprandial glycaemia via stimulating peripheral glucose uptake and suppression of endogenous glucose production.

Q

What are the problems of achieving normoglycaemia with insulin administration?

A

Problems of achieving normoglycaemia with insulin administration:

  • Insulin is injected subcutaneously and absorbed in the peripheral bloodstream instead of portal which can affect absorption.
  • Some short acting insulins are absorbed slowly and should be injected 30 minutes prior to eating

- Action
- Side-effects
- Where use should be avoided
- Blood test measurements where use should be reduced/ stopped
- Use

- Action: stimulate beta cells to secrete insulin (insulin secretagogues).
Bind to SUR-1 receptors on beta cell membrane
Leads to closure of ATP sensitive K+ channel which causes membrane depolarisation, influx of calcium and exocytosis of insulin (makes hypo more likely)
- Side-effects: increased appetite, weight gain, hypoglycaemia
- Benefits: Increased insulin sensitivity, cheap
- Disadvantages: Slow onset of action (3-4 hours)
- Where use should be avoided: Elderly
- Use: 30 minutes before meals
