How many types are there? lots and not always easily differentiated. Formal answer here and far too detailed for most audiences
😱
These are the types from the World Health Organisation Classification 1999
http://whqlibdoc.who.int/hq/1999/WHO_NCD_NCS_99.2.pdf
I think this is accepted world wide (though I doubt if many GPs and Nurses know the details :
1)a
Type 1 a autoimmune
b]
Type I b idiopathic (ie of unknown origin)
11)
Type 2 (may range from predominantly insulin resistance with relative insulin deficiency to a predominantly secretory defect with insulin resistance)
111)
Other (sometimes called
Type 3 .......when published in Diabetes Care for the American Diabetes association they used letters for each subtype, so for example someone who has had a pancreactectomy is sometimes know as having type 3c)
I've only given examples I recognise...some are very rare/little known. There are far more examples in the original text)
a)Genetic defects of beta cell function (ie MODY)
b)Genetci defects of insulin action (eg leprechaunism)
c)Diseases of and trauma to the pancreas (eg pancreatitis, pancreatectomy, cystic fibrosis,haemochomatosis[bronze diabetes]
d)Endocrinopathies (eg Cushings, hypothyroidism,)
e)Drug or Chemical induced (eg glucocorticoids..and several others)
f)Infections (eg congenital rubella)
g)Uncommon forms of immune-mediated diabetes (eg anti-bodies to insulin, stiff man syndrome)
h)Other Genetic syndromes(Downs, Wolframs, Prader Willi,Huntingdons..several others)
(
hope I've spelled all those right!)
The last category )

Gestational
Then there are reports that claim Alzheimers is type 3, diabetes communities who write about 1.5 and the odd article about 'double diabetes' ...type 1 with insulin resistance
.No wonder, we are all different and react differently to different diets and
medications.
I think hyperglycaemia is a sympton... not a disease.
