An overview of diabetes types and treatments


Diabetes is a disease that occurs when your blood glucose, also called blood sugar, is too high. Blood glucose is your main source of energy and comes from the food you eat. Insulin, a hormone made by the pancreas, helps glucose from food get into your cells to be used for energy. Sometimes your body doesn’t make enough—or any—insulin or doesn’t use insulin well. Glucose then stays in your blood and doesn’t reach your cells. Over time, having too much glucose in your blood can cause health problems. Although diabetes has no cure, you can take steps to manage your diabetes and stay healthy.Sometimes people call diabetes “a touch of sugar” or “borderline diabetes.” These terms suggest that someone doesn’t really have diabetes or has a less serious case, but every case of diabetes is serious.

The Role of Insulin in Diabetes

To understand why insulin is important in diabetes, it helps to know more about how the body uses food for energy. Your body is made up of millions of cells. To make energy, these cells need food in a very simple form. When you eat or drink, much of your food is broken down into a simple sugar called "glucose." Then, glucose is transported through the bloodstream to the cells of your body where it can be used to provide some of the energy your body needs for daily activities.

Types:

There are several types of diabetes.

Type 1 diabetes: Also known as juvenile diabetes, this type occurs when the body fails to produce insulin. People with type I diabetes are insulin-dependent, which means they must take artificial insulin daily to stay alive.

Type 2 diabetes: Type 2 diabetes affects the way the body uses insulin. While the body still makes insulin, unlike in type I, the cells in the body do not respond to it as effectively as they once did. This is the most common type of diabetes, according to the National Institute of Diabetes and Digestive and Kidney Diseases, and it has strong links with obesity.

Gestational diabetes: This type occurs in women during pregnancy when the body can become less sensitive to insulin. Gestational diabetes does not occur in all women and usually resolves after giving birth. Less common types of diabetes include monogenic diabetes and cystic fibrosis-related diabetes.

Prediabetes

Doctors refer to some people as having prediabetes or borderline diabetes when blood sugar is usually in the range of 100 to 125 milligrams per deciliter (mg/dL).

Normal blood sugar levels sit between 70 and 99 mg/dL, whereas a person with diabetes will have a fasting blood sugar higher than 126 mg/dL.

The prediabetes level means that blood glucose is higher than usual but not so high as to constitute diabetes.

People with prediabetes are, however, at risk of developing type 2 diabetes, although they do not usually experience the symptoms of full diabetes.

The risk factors for prediabetes and type 2 diabetes are similar. They include:

If a doctor identifies that a person has prediabetes, they will recommend that the individual makes healthful changes that can ideally stop the progression to type 2 diabetes. Losing weight and having a more healthful diet can often help prevent the disease.

How insulin problems develop

Doctors do not know the exact causes of type I diabetes. Type 2 diabetes, also known as insulin resistance, has clearer causes.

Insulin allows the glucose from a person's food to access the cells in their body to supply energy. Insulin resistance is usually a result of the following cycle:

  1. A person has genes or an environment that make it more likely that they are unable to make enough insulin to cover how much glucose they eat.
  2. The body tries to make extra insulin to process the excess blood glucose.
  3. The pancreas cannot keep up with the increased demands, and the excess blood sugar starts to circulate in the blood, causing damage.
  4. Over time, insulin becomes less effective at introducing glucose to cells, and blood sugar levels continue to rise.

In the case of type 2 diabetes, insulin resistance takes place gradually. This is why doctors often recommend making lifestyle changes in an attempt to slow or reverse this cycle.

Excersize and diet tips

A healthy diet can help prevent, reverse, or manage diabetes.

If a doctor diagnoses a person with type 2 diabetes, they will often recommend making lifestyle changes to support weight loss and overall health.

A doctor may refer a person with diabetes or prediabetes to a nutritionist. A specialist can help a person with diabetes lead an active, balanced lifestyle and manage the condition.

Steps a person can take to embrace a lifestyle with diabetes include:

People can also take steps to reduce their body mass index (BMI), which can help some people with type 2 diabetes manage the condition without medication. Slow, steady weight loss goals are more likely to help a person retain long-term benefits.
