Q

what is hyperinsulinaemia?

A

When there is too much insulin in the blood due to insulin resistance. This causes weight gain, high blood pressure, high triglycerides and low HDL-C

Q

What is Diabetic ketoacidosis (DKA)?

A

A serious condition that can lead to a diabetic coma or death in extreme cases. It is when hyperglycaemia is due to a lack of insulin

Q

What is hyperosmolar hyperglycaemic state? HHS

A

Where pancreatic insulin is not effective in controlling blood glucose and therefore blood glucose levels rise, to correct this the body excretes through the urine leading to excessive urination therefore excessive dehydration causing complications

20
Q

What are hypoglycaemic medicines?

A

drugs that are used only in the treatment of type 2 diabetes

21
Q

What is tertiary prevention?

A

A level of preventative care that deals with the rehabilitation and return of a patient to a status of maximum usefulness with a minimum risk of recurrence of the disorder. (This involves a degree of self-care)

22
Q

What does successful management of diabetes usually include?

A

A combination of pharmacological, and lifestyle change interventions.

23
Q

With regards to pharmacological interventions what are the common medications for managing diabetes?

A

Sulphonylureas, meglitinides, biguanides, thiazolidinediones and alpha-glucosidase inhibitors

24
Q

What are some non-pharmacological interventions for diabetes?

A

Dietary advice and exercise + the empowerment of the patient and carer

25
Q

Which psychotropic medications are LESS LIKELY to cause diabetes?

A

Aripiprazole, asenapine, iloperiodone, fluoxetine, and citalopram

26
Q

What triggers type 1 diabetes?

A

The vast majority of type 1 cases are triggered by an autoimmune destruction of the pancreatic beta cells causing an inability to produce insulin

27
Q

What does it mean by autoimmune destruction with Type 1 diabetes?

A

Where the immune system mistakenly identifies the pancreatic beta cells as foreign and attacks and destroys them

28
Q

Why does autoimmune destruction occur?

A

This is mostly unknown although it is thought this is due to genetic susceptibility then at some point in their life an environmental trigger (such as a virus or toxin) activates this susceptibility to bring on the immune response.

29
Q

What causes hyperglycaemia?

A

Insufficient insulin or oral diabetes medication, not injecting insulin properly or using expired insulin, diet, being inactive, illness or infection, certain medications (steroids ect), injury or surgery, and lastly experiencing emotional stress such as family conflict or workplace challenges

30
Q

Does hyperglycaemia or hypoglycaemia require immediate treatment?

A

Hypoglycaemia, this is always a medical emergency due to risk of coma and death

31
Q

How do we prevent hypoglycaemia?

A

BSL monitoring, monitor and encourage food intake, anticipate changes in insulin requirements, give dextrose with insulin infusions (HOSPITAL), educate about symptoms and encourage to report these promptly, and lastly ask patients on insulin about their awareness of hypoglycaemia.

32
Q

What are the different types of insulin?

A

short acting, intermediate acting, long acting, fast acting, and pre-mixed

33
Q

How do we manage type 2 diabetes?

A

With a healthy diet, exercise, weight loss, oral hypoglycaemic, and BP/Lipid monitoring.

34
Q

What do Biganides do?

A

Reduce glucose produce in liver

35
Q

What do Sulphonylureas do?

A

Stimulates the pancreas to release more insulin

36
Q

What so alpha-glucosidase inhibitors do?

A

Slows the digestion and absorption of carbohydrates

37
Q

What do thiazolidnediones do?

A

Increase body tissues sensitivity to insulin

38
Q

Fat blocks insulins ability to what?

A

Work effectively and efficiently

39
Q

High levels of insulin that cannot be utilised effectively is called what?

A

Insulinaemia

40
Q

Can we prevent or cure Type 1 diabetes?

A

There is no known prevention or cure

41
Q

Can we prevent or cure Type 2 diabetes?

A

Evidence weight loss may prevent it

42
Q

When does onset usually occur for people with type 1 diabetes?

A

During childhood and adolescence

43
Q

When does onset usually occur for people with type 2 diabetes?

A

During adulthood but can be diagnosed in children under 15 years

44
Q

what is involved in self-management for those with type 1 diabetes?

A

Daily and often multiple insulin injections or a continuous delivery of insulin with a pump, meticulous attention to blood glucose levels, and a healthy lifestyle to contribute to effective management (routine).

45
Q

what is involved in self-management for those with type 2 diabetes?

A

Good weight control, nutrition, and monitoring of blood glucose levels + potentially the management of oral medication and insulin therapy
