What is Diabetes?



Sugar and Diabetes




Diabetes is the one of the most common diseases worldwide. It has a long course and stays with the patient almost all through his/her life, although many diabetic patients have prolonged symptom free periods but complete cure in most cases remains elusive. One good thing about it is if kept in control, symptom free periods can be long &  patients life remains absolutely normal. To begin with diabetes, few terms need to be understood.


Diabetes - When we say Diabetes, we intend to say Diabetes Mellitus. There's another disease called Diabetes Insipidus which has a different cause and a different pathology.


Diabetes Mellitus  is disease where your body (blood and urine) sugar levels get deranged (hypoglycemia and hyperglycemia) due to lack of an hormone named Insulin. Insulin also has other functions hence diabetes can present with a variety of symptoms and signs.








Pancreas - It is the organ which secretes insulin. Pancreas also secretes other hormones which help in digestion of food.


Diabetes type I or Insulin dependent Diabetes Mellitus (IDDM). As the name suggest "Insulin dependent", patient is completely dependent on external insulin because there is no or very little insulin produced by the body. This form of Diabetes is seen at early age, hence it is also known as Juvenile onset Diabetes Mellitus.


Diabetes type II or Non Insulin dependent Mellitus (NIDDM). In this type, usually patients have normal or even high levels of insulin but the function of insulin is deranged. However in later stages, there may be decrease in insulin levels as well. This type mostly presents at a later stage of life, hence also called as Late Onset Diabetes Mellitus.


There's another special variant which typically presents in pregnancy known as Gestational Diabetes Mellitus.




Enough for the theoretical part, we will continue with Diabetes series in later posts.
Here are some grave Facts about Diabetes Mellitus from credible sources like WHO, National Institute of health NIH (US) :-
  • Estimated cases of diabetes worldwide is 346 million.
  • Diabetes affects 8.3% (25.8 million) of US population.
  • 90% of cases are of type II Diabetes Mellitus.
  • Deaths due to Diabetes are projected to rise 50% in next 10 years.
  • 50% of people with diabetes die due to Cardiovascular complications (Stroke, Heart Disease...)
  • China is projected to lose $558 billion between 2006 & 2015 due to Diabetes and its related complications.
  • China has become Diabetes Capital of the world with 90 million cases (took the notorious title from India in 2011 according to IDF,International Diabetes Federation)


India specific stats:-
  • India has about 61.3 million cases of Diabetes.
  • It affects about 9% urban population & 3% of rural population.
  • Ernakulam, district of Kerala has highest prevalence of around 20% of population.

Complications of  Diabetes Mellitus  are serious and well known. Spectrum of Diabetic complications is vast, from being most trivial to life threatening.  Long term Diabetics are at very high risk of complications if they lack blood sugar control (more likely) and sometimes even otherwise (less likely). High BP and Cholesterol are the other two major harbingers. Inevitably Diabetics fall prey to its complications after several long yrs.  According to WHO,  Diabetes is predicted to become the seventh leading cause of death in the world by the year 2030. Total deaths from diabetes are projected to rise by more than 50% in the next 10 years.   Hence its very essential to have   proper   understanding and accurate knowledge of when to seek medical intervention.

5 Essential Functions of Insulin

People suffering from Diabetes have either the lack of insulin or decreased insulin activity. Insulin is a vital hormone and functions of insulin are essential for life. It is a polypeptide hormone produced by beta cells of islets of Langerhans in Pancreas. It plays an important role in energy metabolism and general growth and development of our body.  Insulin acts in conjunction with Glucagon and other body hormones to maintain the blood glucose levels. Suboptimal glucose levels lead to either hypoglycemia or hyperglycemia both having profound implications on overall health and well being.
