It is a condition in which disturbance of carbohydrates metabolism due to insufficient secretion of insulin hormones. Diabetes is a serious and chronic disease which occurs when your blood glucose or blood sugar is too high.

Diabetes involves a number of diseases and unfortunately there is no cure for it. The diabetic patients need to manage their disease with diet, exercise and medication to stay healthy. Diabetes occurs when our body produces very little or no insulin, or does not use insulin well. Without enough insulin, glucose stays in our blood and doesn’t reach the cells. Glucose level in blood increases. This is known as Hyperglycemia.

Normal blood sugar level:

Fasting: 70-110 mg/dl

Postprandial: 80-150 mg/dl


Types of Diabetes

There are three common types of diabetes.

Type 1 Diabetes

  • In this condition, patient is unable to produce endogenous insulin due to destruction of pancreatic beta cells by genetic immunologic and environmental factors.
  • About 5-10% cases have diabetes type 1.
  • Patients are insulin-dependent, means they need to take artificial insulin daily.
  • It has sudden onset, usually before the age of 30 years (mostly in children)

Type 2 Diabetes

  • 90-95% patients have type 2 diabetes.
  • This diabetes is first treated with diet and exercise and then with oral hypoglycemic agents as needed.
  • It occurs mostly after 40 years of age.
  • About 80% cases are due to obesity.
  • There is no need of exogenous insulin.

Gestational Diabetes

  • Gestational diabetes is a type of diabetes that characterized by any degree of glucose intolerances with onset during pregnancy.
  • Patients with gestational diabetes have greater chance of developing type 2 diabetes later in life.
  • Usually this type of diabetes resolves after the baby is born.

Dietary Management

Doctors refer to some people as having prediabetes when blood glucose level is higher than normal, usually in the range of 100 to 125 mg/dl, but a person does not yet have diabetes.

Prediabetes and high blood glucose level is a risk factor of developing type 2 diabetes, although people do not usually experience the symptoms of full diabetes. If a person is diagnosed with prediabetes, then he should make healthful changes in life that can ideally stop the progression of type 2 diabetes, like weight loss and healthy diet.
