Type 1 diabetes is when no insulin is produced at all because the insulin-producing cells in the pancreas have been destroyed. Nobody knows for sure why these cells have been damaged but the most likely cause is the body having an abnormal reaction to the cells. There is nothing that you can do to prevent Type 1 diabetes. This type of diabetes is always treated with insulin injections.

Type II this type is more common and accounts for over 90% of all diabetes cases around the world and is largely the result of excess body weight and physical inactivity (WHO). People with this type produce too little insulin or the insulin they produce cannot work properly because their body has become resistant to insulin.

This form is more common in people over 40 years of age but it is becoming much more common in young people as well as childhood obesity is now increasing. Obese people and people who have a relative already suffering from this disease are more likely to be affected.

Approximately 90% of patients with type 2 diabetes are obese. Half of the cases of type 2 diabetes are without symptoms and can only be discovered with testing sugar (glucose) in the urine or blood.

It has been estimated that it takes approximately seven years from the start of the disease to be diagnosed. This means that unknown high blood sugar levels are silently working damage in the body and often at the moment of diagnoses a patient present with one or all of the following symptoms like bad eye sight, pains in feet and hands, extreme tiredness, unnatural thirst, ulcers on the legs and in advanced cases the first symptom can be heart attack or stroke.

What are common consequences of diabetes?

Over time, diabetes can damage the heart, blood vessels, eyes, kidneys, and nerves.

  • Diabetes increases the risk of heart disease and stroke. 50% of people with diabetes die of cardiovascular disease (primarily heart disease and stroke).
  • Combined with reduced blood flow, neuropathy in the feet increases the chance of foot ulcers and eventual limb amputation.
  • Diabetic retinopathy is an important cause of blindness, and occurs as a result of long-term accumulated damage to the small blood vessels in the retina. After 15 years of diabetes, approximately 2% of people become blind, and about 10% develop severe visual impairment.
  • Diabetes is among the leading causes of kidney failure. 10-20% of people with diabetes die of kidney failure.
  • Diabetic neuropathy is damage to the nerves as a result of diabetes, and affects up to 50% of people with diabetes. Although many different problems can occur as a result of diabetic neuropathy, common symptoms are tingling, pain, numbness, or weakness in the feet and hands.
  • The overall risk of dying among people with diabetes is at least double the risk of their peers without diabetes.


Simple lifestyle measures have been shown to be effective in preventing or delaying the onset of type 2 diabetes. To help prevent type 2 diabetes and its complications, people should:

  • achieve and maintain healthy body weight;
  • be physically active – at least 30 minutes of regular, moderate-intensity activity on most days. More activity is required for weight control;
  • eat a healthy diet of between three and five servings of fruit and vegetables a day and reduce sugar and saturated fats intake;

An interesting and important study from Finland confirms that sustained changes in lifestyle can substantially reduce the development of type 2 diabetes in middle-aged adults at high risk for diabetes (Finnish Diabetes Prevention Study, N Engl J Med 2001 May 3;344 (180):1343-50).

VLCKD to treat diabetes

It has recently been found that the use of a very low calorie diet can actually reverse Type 2 diabetes. http://www.orsmondclinics.com/index.php?/blog/detail/very-low-calorie-diet-to-defeat-type-2-diabetes
