Diabetes is characterized by chronic hyperglycemia, that is to say an excess of sugar in the blood and therefore a level of glucose (blood sugar) that is too high.


Diabetes mellitus, known as Diabetes, refers to a class of diseases that damage the way your body uses blood sugar (glucose). The function of glucose is vital for your health; it is an essential energy source for the cells that create tissues and muscles. Glucose is the main source of fuel for your brain.

There are different types of Diabetes, which can lead to excess sugar in the blood. Too much sugar in the blood can cause serious health problems.

Chronic Diabetic diseases include type 1 diabetes and type 2 diabetes. Reversible diabetic diseases include prediabetes; this happens when the blood sugar level is higher than normal. However, it is not high enough to be classified as Diabetes. Gestational Diabetes occurs during pregnancy but can be cured once the baby is born.

Causes of Diabetes

  • Diabetes type 1 (once known as juvenile diabetes or insulin-dependent diabetes)

There's no exact cause for Type 1 Diabetes. The immune system fights off harmful bacteria or viruses, destroying the cells that make insulin in the pancreas, leaving your body with little or no insulin. Sugar accumulates in the bloodstream instead of being transported to your cells.

  • Prediabetes and Type 2 Diabetes

Cells become strong to the action of insulin, and the pancreas cannot make the insulin it needs. Causing sugar to build up in your bloodstream, instead of passing into your cells necessary for energy.

It is believed that its a consequence of various genetic and environmental factors. Being overweight is one of the causes of the development of type 2 diabetes, but not all overweight people have diabetes.

Prediabetes means you have a high sugar level in your blood. It is not yet high enough to be considered type 2 diabetes, but without a lifestyle change, adults and children with prediabetes are more likely to develop type 2 diabetes.

  • Gestational diabetes

In the period of pregnancy, the placenta produces hormones to aid in pregnancy. Hormones allow your cells to become more resistant to insulin.

The pancreas generally produces less extra insulin to overcome this resistance. Despite this, sometimes the pancreas cannot keep up, causing insufficient glucose to reach your cells, remaining in your blood; this can cause gestational diabetes.

Symptoms of Diabetes

Symptoms vary depending on the type of Diabetes and the amount of rising sugar. In general, patients with prediabetes or type 2 Diabetes do not usually have symptoms at first. Symptoms in type 1 Diabetes usually appear quickly and are more severe.
