Causes and Types of Diabetes

Diabetes is a condition that directly affects the functioning of pancreas. It is located right behind the stomach and secretes insulin into blood. Insulin allows the body to absorb sugars and fats from the food we eat. If a person is suffering from diabetes, it’s a clear indication the functioning of pancreas is permanently affected. The pancreas of a person with diabetes:

  1. Doesn’t secrete enough insulin.
  2. Doesn’t secrete insulin at all.
  3. Does secrete insulin but it doesn’t work as it supposed to.


Causes and Types of Diabetes












Causes of Diabetes

Although, all the reasons are not yet completely known but the most common causes include:

  1. Being Over-weight (obesity)
  2. Age (More is the age, higher is the chance)
  3. Family history of diabetes
  4. Taking certain medicines
  5. Physical inactivity
  6. Abnormal glucose production by liver
  7. Insulin resistance
  8. Metabolic syndrome
  9. Beta cell dysfunction
  10. History of gestational diabetes

If diabetes is overlooked, the cells starts starving for energy despite of high blood glucose level. With time, the situation worsens and leads to:

  • Heart disease,
  • Heart stroke,
  • Blindness,
  • Kidney disease,
  • Amputations and
  • Dental disease

Types of Diabetes

There is mainly 2 types of diabetes:

  1. Type 1 diabetes
  2. Type 2 diabetes

Causes and Types of Diabetes










Type 1 Diabetes

Type 1 diabetes is caused due to the destruction of beta cells in pancreas that produces insulin. This destruction is caused by body’s own immune system (an auto-immune disease). Normally the function of immune system is to destroy any potentially harmful foreign substance including bacteria and viruses. But in auto-immune disease, body’s own cells start getting attacked by the immune system. The symptoms of Type 1 diabetes usually develop in shorter period of time while beta cell destruction continues for several years.

Type 1 diabetes can happen in any age but it typically develops in young adults and children.

Type 2 Diabetes

Type 2 diabetes is most common form of diabetes which is caused by multiple factors (mentioned above). It is developed when the pancreas can no longer produce the required insulin. Old aged and middle aged people are more susceptible to suffer from type 2 diabetes. The symptoms can be subtle and people may remain undiagnosed for years.
