Diabetes

  Diabetes, a metabolic disorder, in which there is a disturbance in the glucose metabolism in  our body.Glucose is vital to your health because it's an important source of energy for the cells that make up our muscles and tissues. It's also our brain's main source of fuel
  The underlying cause of diabetes varies by type. But, no matter what type of diabetes you have, it can lead to excess sugar in your blood. Too much sugar in your blood can lead to serious health problems.Chronic diabetes conditions include type 1 diabetes and type 2 diabetes.
      Diabetes symptoms vary depending on how much your blood sugar is elevated. Some people, especially those with prediabetes or type 2 diabetes, may not experience symptoms initially. In type 1 diabetes, symptoms tend to come on quickly and be more severe.

Some of the signs and symptoms of type 1 and type 2 diabetes are:

• Increased thirst
• Frequent urination
• Extreme hunger
• Unexplained weight loss
• Presence of ketones in the urine (ketones are a byproduct of the breakdown of muscle and fat that happens when there's not enough available insulin)
• Fatigue
• Irritability
• Blurred vision
• Slow-healing sores
• Frequent infections, such as gums or skin infections and vaginal infections

To understand diabetes, first you must understand how glucose is normally processed in the body.

How insulin works
Insulin is a hormone that comes from a gland situated behind and below the stomach (pancreas).

• The pancreas secretes insulin into the bloodstream.
• The insulin circulates, enabling sugar to enter your cells.
• Insulin lowers the amount of sugar in your bloodstream.
• As your blood sugar level drops, so does the secretion of insulin from your pancreas.

The picture shown below, in my opinion is the most comprehensive way to sum up this disorder and it's prevention.
