Diabetes: symptoms and treatments

Diabetes is a chronic disease that is characterised by a raised blood glucose level. There are many ways to prevent, control and treat it.

What Is the Diabetes?

Diabetes is a chronic disease caused by a deficiency in the production of insulin by the pancreas, or by the ineffectiveness of the insulin produced. Such a deficiency leads to increased concentrations of glucose in the blood, which can damage many parts of our body’s systems (especially the blood vessels and nerves). Over time It can also cause other problems, like heart disease and blindness. If you or someone around you has diabetes and you would like to have a consultation, you can always contact us for an English doctor in Barcelona.

There are two main types of diabetes and both are caused by the failure of producing or using insulin, a hormone that makes sure that cells can use glucose (known as blood sugar).

  • Type 1 diabetes (known as insulin-dependent):  the pancreas is failing in the production of the insulin which is essential for our body. This type of diabetes can be seen most frequently in children and adolescents, but it can appear later in life as well.
  • Type 2 diabetes (known as non-insulin dependent):  when the body is not able to respond to the action of insulin produced by our pancreas. According to the World Health Organization,  the type 2 diabetes is more common than type 1, 90% of all diabetes cases around the world are from this type. It can be found more frequently in adults but is being noted in adolescents as well. The type 2 diabetes is also frequent in obese or overweight people.
