5. DEFINITION
5
According to both World Health Organisation (WHO) & American
Diabetic Association (ADA):-
“ Diabetes is a group of metabolic disorders characterized
by hyperglycemia resulting from defects in insulin
secretion, insulin action or both.”
6. Contd…
6
On the basis of etiology, pathogenesis, biochemical features and
implications of diabetes mellitus:
“Diabetes is a metabolic cum vascular syndrome of multiple
etiology characterized by chronic hyperglycemia with
disturbances of carbohydrate , fat and protein metabolism
resulting from defects in insulin secretion and action or both
leading to changes in both small vessels (microangiopathy) and
large blood vessels (macroangiopathy).”
7. CLASSIFICATION
7
WHO classification of diabetes mellitus:
1. Diabetes mellitus (DM)
• Type 1 or insulin - dependent diabetes mellitus.
• Type 2 or non insulin - dependent diabetes mellitus.
• Malnutrition related - diabetes mellitus.
• Other types (secondary to pancreatic, hormonal, drug-induced, genetic and
other abnormalities)
2. Impaired glucose tolerance (IGT)
3. Gestational diabetes mellitus (GDM)
8. TYPE 1 - INSULIN DEPENDENT DM
8
Most severe form of disease.
Abrupt onset.
Incidence is higher among 10-14 yrs old group.
Immune mediated in 90% and idiopathic in < 10%.
Catabolic disorder => circulating insulin is virtually absent,
plasma glucagon is elevated and
beta cells fail to respond to all insulinogenic stimuli.
Exogenous insulin is required to reverse catabolic state, prevent ketosis,
reduce hyperglucagonaemia and reduce blood glucose.
9. 9
TYPE 2 – NON-INSULIN DEPENDENT DM
9
More common.
Gradual onset.
Middle-aged and elderly.
Most frequently mild, slow ketosis and is compatible with long
survival if given adequate treatment.
Clinical picture usually complicated by the presence of other disease
processes.
10. 10
GESTATIONAL DIABETES
Hyperglycemia with blood
glucose values above normal but
below those diagnostic of
diabetes, occuring during
pregnancy.
High-risk pregnancy.
Women and their children are at
increased risk of type 2 DM in
the future.
IMPAIRED GLUCOSE
TOLERANCE
A state indermediate – “ at-risk
group” – between diabetes
mellitus and normality.
11. Insulin resistance syndrome (Syndrome X)
11
In obese patients with type 2 diabetes , the association of hyperglycemia,
hyperinsulinaemia , dyslipidemia and hypertension, which leads to
coronary artery disease and stroke , may result from a genetic defect
producing insulin resistance with latter being exaggerated by obesity.
13. Problem statement
13
WORLD:-
In 2014, the number of cases of diabetes were estimated to be 422
million, of these > 90 % are type 2 diabetes.
In 2016 , an estimated 1.6 million people died from consequences of
high blood sugar.
More than 80 % diabetes death occur in low and middle income
countries.
14. 14
The global prevalence of diabetes was estimated to be 8.5% in
adults aged 18+ years.
Low income countries showed the lowest prevalence (8% for both
sexes), and the upper-middle-income countries showed the highest
(10% for both sexes).
The age adjusted mortality rates among the people with diabetes
are 1.5 - 2.5 times higher than in the general population.

16. People living with diabetes worldwide per region in
2017 and 2045 (20-79 years)

21. Agent
21
Underlying cause => insulin deficiency.
May be due to wide variety of mechanisms:-
Pancreatic disorders: inflammatory , neoplastic, and others such as cystic
fibrosis.
Defects in formation of insulin.
Destruction of beta cells.
Decreased insulin sensitivity genetic defects
Auto immunity.
22. Host factors
22
Age:- Type 2 diabetes begins to rise in the middle years of life.
- The prognosis is worse in younger diabetes who tend to develop
complications earlier than older diabetes.
Sex :- In some countries the overall male – female ratio is about equal.
- In South-east Asia, an excess of male diabetes has been observed.
23. 23
Genetic factors:-
The genetic nature of type 2 diabetes is undisputed. Twin studies showed that in
identical twins who developed type 2 diabetes concordance was approximately
90% showing strong genetic component.
Genetic markers:-
Type 1 diabetes is associated with HLA B-8 & HLA B-15 ,HLA-DR3 AND DR4.
Type 2 is not associated with HLA.
Contd…
24. 24
Immune mechanisms:- Evidence of both cell mediated and of humoral
activity against islet cells.
Obesity:- Is a risk factor for type 2 diabetes and risk is related to both
duration and degree of obesity.
Central obesity is also an important determinant of insulin resistance.
Voluntary weight loss improves insulin sensitivity and reduce risk of
progression from impaired glucose tolerance to type 2 diabetes.
No role in type 1 diabetes.
Contd…
25. 25
Maternal diabetes:-
- Offsprings of diabetic pregnancies including gestational diabetes are
often large and heavy at birth, tend to develop obesity in childhood and
risk of developing type 2 diabetes at early age.
- Maternal diabetes associated with IUGR and LBW , appears to
increase the risk of subsequent diabetes in the child.
Contd…
26. Environmental risk factors
26
Sedentary lifestyle
Diet
Dietary fibres
Malnutrition
Alcohol
Viral infection ( by rubella, mumps and human coxsackie virus)
Chemical agents ( alloxan, streptozotocin, valcor , etc.)
Stress
Other factors such as social class.
28. Urine Examination
28
Urine test for glucose:- 2 hours after meal.
All those with glucosuria are considered diabetic unless otherwise proved by a standard
oral glucose tolerance test.
The test yield too many false negatives.
Glucosuria may also be found in perfectly normal people which give rise to false
positives.
For these reason urine testing is not considered an appropriate tool for case finding.
29. Blood sugar testing
29
Standard oral glucose test remains the cornerstone of diagnosis of
diabetes .
Mass screening programs have used glucose measurements of fasting ,
PP or random samples.
For epidemiological purposes, the 2-hour value after 75 g oral glucose
may be used either alone or with the fasting value.
30. The WHO recommendation for diagnostic criteria for diabetes (2019)
30
* Overnight fast of 8-14 hours.
** If laboratory measurement not available, point of care, (“finger-stick”) devices can be used (they report glucose
values in capillary plasma).
*** Plasma glucose is preferred in people with symptoms who are suspected of having type 1 diabetes.
Measurement Diagnostic cut-off value

32. Target population
32
Screening of high risk groups.
Those in age group of > 40 years.
Those with a family history of diabetes
The obese
Women who have had a baby weighing more than 4.5 kg
Women who show excess weight gain during pregnancy
Patients with premature atherosclerosis.
35. Population strategy
35
Scope for prevention of Type 1 diabetes - LIMITED.
For Type 2 diabetes - Development of prevention programmes to
eliminate environmental risk factors.
To press need for PRIMORDIAL PREVENTION.
36. Contd…
36
Preventive measures:-
Maintainance of normal body weight.
Healthy Nutritional habits and physical exercise.
These measures maybe integrated with other community-based
programmes for the prevention of non-communicable diseases
(e.g coronary artery diseases).
37. High risk strategy
37
Since NIDDM appears to be linked with sedentary life style , over nutrition
and obesity, correction of these may reduce the risk of diabetes.
Since alcohol may directly increase the risk of diabetes, it should be avoided
Subjects at risk should avoid diabetogenic drugs like oral contraceptives.
Reduce factors that promote atherosclerosis e.g smoking, high BP, elevated
cholesterol and high TG levels.
38. SECONDARY PREVENTION
38
The aim of treatment are :-
To maintain blood glucose levels as
close within the normal limits
To maintain ideal body weight
Treatment is based on :-
Diet alone – small balanced meals
more frequently.
Diet and oral anti diabetic drugs
Diet and insulin
39. 39
Proper management of diabetes is more important to prevent complications.
Routine checking of blood sugar, of urine for proteins and ketones, of BP,
visual acuity and weight should be done periodically.
Examination of feet for any defective blood circulation, loss of sensation
and health of skin.
Primary health care is of great importance to diabetic patients since most
care is obtained at this level.
Contd…
40. 40
GLYCOSYLATED HAEMOGLOBIN :-
Should be estimated at half yearly intervals.
Provides a long term index of glucose control.
The percentage of such glycosylated haemoglobin reflects the mean blood
glucose levels during the red cell life-time (i.e. past 2-3 months)
41. 41
SELF CARE:-
Crucial element in secondary
prevention.
By adherence to diet and drug
regimens.
Blood glucose monitoring
Self administration of insulin
Abstinence from alcohol
Maintenance of optimum weight
Attending periodic check-ups.
Recognition of symptoms associated
with hypoglycaemia.
42. Individual intervention in diabetes with evidence of
efficacy.
42
Interventions with evidence of efficacy Benefits
Lifestyle interventions for preventing type 2 diabetes
in people of high risk
Reduction of 35-58 % in incidence
Metformin for preventing type 2 diabetes for people
at high risk
Reduction of 25-31 % in incidence
Glycaemic control in people with HbA1c greater
than 9%
Reduction of 30% in microvascular disease per 1%
drop in HbA1c
Blood pressure control in people whose pressure is
higher than 130/80 mmHg
Reduction of 35% in macrovascular and
microvascular disease per 10mmHg drop in BP
Annual eye examinations Reduction of 60-70% in serious vision loss
Foot care in people with high risk of ulcers Reduction of 50-60% in serious foot disease
ACE inhibitor use in all people with diabetes Reduction of 42% in nephropathy; 22% drop in
cardiovascular disease.
43. 43
Home blood glucose monitoring:- capillary blood glucose measurements.
Education of patients and their families.

44. TERTIARY PREVENTION
44
The main objective at the tertiary level is to organize specialized
clinics and units capable of providing diagnostics and
management skills of a high order.
To limit the development of further disability in a diabetic
person, who came late with complications
The tertiary level should also be involved in basic, clinical and
epidemiological research.

Ethnic groups in many
industrialized countries appear to
be especially susceptible to the
development of obesity and it’s
complications.
DRUGS:
Cortico-steroids, contraceptives,
insulin, ß-adrenergic blockers,

BACKGROUND
Non-communicable diseases
(NCDs) => leading cause of adult
mortality and morbidity
worldwide.
NCDs are rapidly increasing
globally and have reached
epidemic proportions in many
countries.
Major Public Health challenge.
Largest contribution (upto
70%) by 4 types of NCDs viz.
Cardiovascular Diseases,
Cancer, Chronic respiratory
diseases and Diabetes.

DISEASE BURDEN
Globally, NCD deaths are projected to increase from 38 million in
2012 to 52 million by 2030.
The 4-major NCDs are responsible for 82% of NCD deaths.
Approximately 42% of all NCD deaths occurred before the age of
70years globally.
48% of NCD deaths in low- and middle- income countries and
28% in high-income countries were in individuals aged under
70years.
70. Contd…

In India, NCDs contribute to around 5.82 million deaths that
account for 61% of all deaths.
India shares more than 2/3rd of the total deaths due to NCDs in
the South-East Asian Region (SEAR) of WHO.
The probability of dying between ages 30 and 70 years from 4-
major NCDs is 26%.
