Diabetes is the seventh leading cause of death in the United States. It affects 26 million Americans and causes an annual loss of 174 billion dollars. The disease affects almost all organs of the body, leading to considerable morbidity.

Diabetes is a type of metabolic disorder in which the patient’s blood glucose level remains above the normal.

This could be either because the pancreas produces insufficient quantities of insulin or because the cells of the body are unable to utilize this insulin.

The common symptoms of diabetes include polyphagia (increased hunger), polydipsia (increased thirst) and polyuria (increased urination).

Incidence of diabetes in America

According to the latest statistics, diabetes has already struck 8.3% of the entire American population.

Around 26 million Americans suffer from diabetes, out of which 18.8 million people have been diagnosed with the condition; while in another 7 million, the disease is yet to be diagnosed. Apart from this, 79 million Americans suffer from a condition called as pre-diabetes, i.e., they run a high risk of developing diabetes. If nothing drastic is done in the coming years to control the disease, experts believe that by 2050, one in every three Americans would develop diabetes.

Diabetes can be divided into three common types:

  • Type I diabetes
  • Type II diabetes
  • Gestational diabetes

As type II diabetes alone accounts for around 90% to 95% of all diabetes cases worldwide, we will focus on it first.

Type II diabetes

Type II diabetes is the condition in which either the patient does not produce sufficient quantities of insulin, or the cells of the body develop insulin resistance, i.e., they are unable to utilize the insulin to facilitate the entry of the glucose into the cells.

Insulin resistance by the cells produces two effects:

  • The amount of glucose present in the blood increases.
  • The cells do not get adequate amount of glucose needed to meet their energy requirements and for their growth.
Type II diabetes generally develops later in life.

Experts tell us that it is more of a lifestyle disease caused due to obesity. The central obesity, i.e., the amount of fat concentrated around the waist in relation to the organs present in the abdomen, is the main reason behind the increased risk of developing diabetes. 

It is the excessive abdominal fat rather than the fat collected under the skin that is responsible for diabetes.

The abdominal fat releases a group of hormones known as adipokines which impair the glucose tolerance.

Patients suffering from type II diabetes can bring their disease under control by taking care of their diet and exercising regularly to bring down their body weight. But it is important to remember that once the body cells develop resistance to insulin, this tendency tends to continue. Therefore, even when a patient of type Ii diabetes has lost excess weight, he has to continue with his healthy lifestyle pattern to keep the blood sugar under control.

The main risk factors for type II diabetes include:

  • Age and ethnicity: people above the age of 40 are more likely to develop the condition. It has also been seen that people of South Asian origin and blacks are five times more prone to develop type II diabetes.
  • Positive family history: You are more likely to develop diabetes if your close family members suffer from the condition
  • Body-weight: Four-fifths of all type II diabetes patients were overweight when they developed the disease.
  • Cardiovascular diseases and stroke: Hypertension, heart attack and stroke increase the chances of developing type II diabetes.
  • Gestational diabetes: Women who develop diabetes during pregnancy or give birth to a large baby are more likely to develop type Ii diabetes later on.
  • Impaired glucose tolerance: People who have been diagnosed with impaired glucose tolerance are more prone to develop the condition.
As patients of type II diabetes produce some amount of insulin, they are usually prescribed oral anti-diabetic medicines to improve insulin production, regulate the amount of glucose being released from the liver and to overcome insulin resistance by the cells.

Later on in the course of the disease, when the pancreas is no longer able to produce enough insulin, the patient may need insulin therapy to control the blood glucose levels.
