Q

How does depression act as a CHD risk “enhancer”?

57
Q

What is Type II diabetes?

A

Results from an imbalance between insulin production and responsiveness that causes insulin resistance

58
Q

How does insulin resistance occur?

A
  • Cells need energy in the form of glucose
  • Insulin, a hormone produced by the pancreas, is produced when glucose levels rise in the blood
  • Insulin is supposed to make cells take up glucose that is available in the blood
  • However, cells can ignore insulin and not take up glucose, i.e. insulin resistance
  • Glucose continues to stay in the blood. The pancreas detects that blood glucose levels are still high. To bring it to normal, it produces even more insulin to tell cells to take up the glucose
  • Over time the increase production of insulin actually increases insulin resistance
  • Pancreas can no longer keep up, insulin production falls, leaving blood glucose levels perpetually high
59
Q

What is insulin?

A

A hormone produced by the pancreas, which is produced when glucose levels rise in the blood and supposed to make cells take up glucose available in the blood

60
Q

What are the common symptoms of diabetes?

  • Blood vessels: Damage blood vessels, leads to circulation problems
  • Kidney: Kidney failure
  • Diabetic neuropathy: Nerve damage, can evolve to gangrene and lead to amputation
63
Q

What are the ways to manage Type II diabetes?

A

Being unaware of serious health implcations -> undermine adherence to treatment

66

A

Helps with adherence to treatment programs

67
Q

Why are therapeutic interventions needed to help to manage Type II diabetes?

How is engaging in self-blame a double-edged sword?

A

Can motivate patients to assume responsibility and control over their condition

But it can also lead to guilt and depression
