Blood

HbA1c, FBC, U&E, LFTs, calcium, fasting lipid profile, Vit B12, TSH

If they have a new diagnosis of Type 2 diabetes they should also have an Iron profile

Urinalysis

Albumin creatnine ratio

A telephone/email service is provided by the Diabetes Nurse Specialist, for support and advice to patients and health professionals. This is available from 8am to 4.30pm, Monday to Friday.

Diagnostic criteria for diabetes

Type 2 Diabetes

Glucose units in mmol/L

SYMPTOMATIC

(eg. polyuria, polydipsia, unexplained weight loss)

ASYMPTOMATIC

A single fasting plasma glucose ≥ 7

OR

A single random plasma glucose ≥ 11.1

A fasting plasma glucose ≥ 7 on two separate occasions

OR

A random plasma glucose ≥ 11.1 on two separate occasions

OR

An * HbA1c ≥ 6.5% (48mmol/mol) on two separate occasions

OR

An * HbA1c ≥ 6.5% AND a single elevated plasma glucose
(fasting ≥ 7 or random ≥ 11.1)

 

Impaired Fasting Glucose (IFG)

Pre-Diabetes

Impaired Glucose Tolerance (IGT)

Fasting plasma glucose

6.1 – 6.9 mmol/L

HbA1c 5.7 – 6.4%

(39 – 47 mmol/mol)

2 hour plasma glucose

 7.8 – 11.0 mmol/L

(after 75g oral glucose load)

 

The clinical management of IFG, pre-diabetes and IGT is similar, ie. education on lifestyle changes to increase physical activity, eat a healthier diet and lose weight.

* Caution with use of HbA1c for diagnosis of diabetes:

An HbA1c of < 6.5% (48mmol/mol) does not exclude diabetes.

HbA1c cannot be used in cases of increased red cell turnover (pregnancy, anaemia, haemoglobinopathies) or rapid rise in sugar levels (type 1 diabetes, acute illness, steroids).

Criteria for testing for type 2 diabetes in asymptomatic adults

Consider in all adults who are overweight (BMI ≥ 25kg/m2) and have additional risk factors:

  • Physical inactivity
  • First degree relative with diabetes
  • High-risk ethnicity (eg African, Latino, Asian)
  • Women who delivered a baby weighing > 9lb (4kg) or who were diagnosed with gestational diabetes
  • Hypertension (≥ 140/90mmHg or on antihypertensive therapy)
  • HDL cholesterol < 0.9mmol/L and/or triglyceride > 2.8mmol/L
  • Women with PCOS
  • Severe obesity
  • History of cardiovascular disease

In the absence of the above criteria, testing should begin age 45 yrs

If the results are normal, repeat testing at 3-year intervals, with consideration of more frequent testing depending on initial results and risk status eg those with pre-diabetes should be tested yearly.

Micro-albuminuria screening should be conducted annually.

Send first void urine in the absence of urinary tract infection for Albumin Creatinine Ratio (ACR).

An abnormal result of >2.5mg/mmol is an indication to repeat the test twice within the following 4 months.

  • If both results are normal repeat annually
  • If two of the three tests are abnormal micro-albuminuria is confirmed

The following can affect the reliability of the test:

  • Exercise within previous 24 hours
  • Infection
  • Congestive Heart Failure
  • Marked hyperglycaemia
  • UTI
  • Haematuria
  • Pregnancy

The National Weight Control Registry (NWCR)
http://www.nwcr.ws

The largest prospective investigation of long-term successful weight loss maintenance, the NWCR was developed to identify and investigate the characteristics of individuals who have succeeded at long-term weight loss. The NWCR is tracking over 10,000 individuals who have lost significant amounts of weight and kept it off for long periods of time. Research findings report how they achieved and maintained this weight loss. Some key messages include:

  • 78% eat breakfast every day.
  • 75% weigh themselves at least once a week.
  • 62% watch less than 10 hours of TV per week.
  • 90% exercise, on average, about 1 hour per day
