Every year on November 14,
World Diabetes Day brings diabetes
to the attention of the world.
November 14 is the
birthday of Frederick
Banting, one of the
discoverers of insulin.

The global symbol for diabetes was developed during
the Unite for Diabetes campaign.

Why a circle?
A positive symbol across cultures, the circle
symbolizes life and health.

Why blue?
The colour blue reflects the sky that unites all nations.
The blue border of the circle reflects the colour of the
sky and the flag of the United Nations. The blue circle
signifies the unity of the global diabetes community
in response to the diabetes epidemic.

Diabetes Mellitus
• The name “diabetes mellitus means sweet
urine. It stems from ancient times when
physicians would taste a patients urine as a
part of a diagnosis.
Definition
• Hyperglycemia due to Absolute or relative
deficiency of insulin.
What is Diabetes?

• A condition in which the
body cannot make or
cannot use insulin
properly
Diabetes
• A fast growing disease
• Diabetes is a major chronic disease affecting
many individuals, for which very high growth
rates are expected in the coming years.
• Due to changes in lifestyles more human
beings are becoming diabetic patients.
• The number of diabetes cases is increasing
day by day.
The Impact of Diabetes:

•
•
•
•
•

Million lives are lost annually
Millions of $ lost income and Productivity.
1 million amputation per year.
Diabetes kills 1 person in every 8 seconds.
Every 10 seconds, 2 people develop diabetes.

3,600 new cases of diabetes are diagnosed
580 people die of diabetes-related complications
225 people have a diabetes-related amputation
120 people with diabetes progress to end-stage renal
disease
55 people with diabetes become blind

INDIAN SCENARIO
High prevalence
Life style changes further accentuate the high genetic predisposition
Under diagnosed due to low awareness
Perhaps occurs a decade earlier
Non obese/lean Type II fairly common
Treated less seriously as considered “Mild Disease”

Types of Diabetes Mellitus
Type 1

Type 2

Gestational DM
Type 1 Diabetes Mellitus
• Formerly known as “juvenile onset” or
“insulin dependent” diabetes
• Most often occurs in people under 30 years
of age, but may occur at any age.
• Peak onset between ages 11 and 13
Type 1 Diabetes Mellitus
Etiology and Pathophysiology
• Progressive destruction of pancreatic 
cells
• Autoantibodies cause a reduction of 80%
to 90% of normal  cell function before
manifestations occur
Type 1 Diabetes Mellitus
Etiology and Pathophysiology
• Causes:
– Genetic predisposition
– Exposure to a virus
Type 1 Diabetes Mellitus
Onset of Disease
• Manifestations develop when the
pancreas can no longer produce insulin
– Rapid onset of symptoms
– Present at ER with impending or actual
ketoacidosis
Type 1 Diabetes Mellitus
Onset of Disease
•
•
•
•
•
•

Weight loss
Polydipsia (excessive thirst)
Polyuria (frequent urination)
Polyphagia (excessive hunger)
Weakness and fatigue
Ketoacidosis
Type 1 Diabetes Mellitus
Onset of Disease
• Diabetic ketoacidosis (DKA)
– Life-threatening complication of Type 1 DM
– Occurs in the absence of insulin
– Results in metabolic acidosis
Type 2 Diabetes Mellitus
• Formerly known as “adult onset” or “
Non insulin dependent Diabetes”.
• Accounts for >90% of patients with
diabetes
• Usually occurs in people over 30 years
old
• 80-90% of patients are overweight
Risk Factors for Type 2 Diabetes
• Age
 Obesity
• Race/ethnicity
 Physical inactivity
• Previous gestational diabetes (GDM)
 Impaired fasting glucose levels • Family history of diabetes
 Impaired glucose tolerance (IGT)  Body fat distribution

Can be modified
What Happens in Type 2 DM
Stomach empties 50%
faster than normal

Pancreas can’t make
enough insulin

Type 2
Diabetes
Liver puts too
much sugar
into the blood

Muscle cells and other tissues are
resistant to insulin
Type 2 Diabetes Mellitus
Onset of Disease

Editor's Notes

  • #12 In 2010, it was estimated that over 300 million people worldwide were affected by diabetes. Within 20 years this number is expected to soar to about 500 million. This is an increase of more than 50%.Much of this increase will occur in the Indian and Asian subcontinents, due to a complex interplay of genetic, environmental and social factors, such as rural-urban migration and industrialisation.International Diabetes Federation. (2009). IDF Diabetes Atlas, 4th Ed. Brussels.
  • #13 New in this edition:China takes the top spot, with India close behind. This is heavily influenced by the new study published in 2010. Our estimates are just under theirs at 90 million (compared to 91 million) and can be attributed to different age groups and a somewhat more conservative approach.Increases and changes in the position of countries relative to each other can be explained mostly by an ageing population and changes in urbanisation.Note, the BRIC countries are all in the top 10. Only the US is a high-income country.
