  • 8. Diagnosis
of
Diabetes
Mellitus. 




Diabetes
symptoms
(polyuria,
polydipsia) Random Laboratory venous plasma glucose > 11.1 mmol/l. Random Laboratory fasting venous plasma glucose > 7.0 mmol/l. Advisable to have two tests results to confirm diagnosis, or one oral glucose tolerance test.  Oral glucose tolerance test (OGTT). Patient takes 75g oral glucose and two hours later has bloods taken, if venous plasma glucose >11.1 mmol/l, Diabetes is diagnosed. More recently the WHO have agreed to use the HbA1c as a method of diagnosis

  • 10. The
physiology
of
normal
blood
 • The
pancreas
controls
blood
glucose
levels. • It
lies
behind
the
stomach. • The
pancreas
does
two
jobs:
 
 
 1.
Produces
pancrea9c
juices
which
aids
food
diges9on.Alpha cells release Glucagons, which increases blood glucoseby prompting the release of glucose (from the Liver) into theblood.Beta cells release Insulin, a hormone which encouragesthe absorption of glucose into muscle cells, fat cells, andconnective tissue cells etc, this reduces blood sugars.

diagnosedType 1Diet, exercise + InsulinType 2Diet and exercise for 3 months ↓Oral hyperglycaemic agent:Sulphonylurea for those not overweight (eg. Gliclazide, Glibenclamide)Biguanide for those overweight (eg. Metformin)Can use together if not individually effective ↓Newer agents – Glitazones, Gliptins and GLP-1 ↓ Insulin Metformin can also be added if patient is overweight
