Diabetes is a condition that impairs the body’s ability to process blood glucose, otherwise known as blood sugar.

Three major diabetes types can develop: Type 1, type 2, and gestational diabetes.

Type I 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.

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

Diabetes is a condition that impairs the body’s ability to process blood glucose, otherwise known as blood sugar.

Without ongoing, careful management, diabetes can lead to a buildup of sugars in the blood, which can increase the risk of dangerous complications, including stroke and heart disease.

Different kinds of diabetes can occur, and managing the condition depends on the type. Not all forms of diabetes stem from a person being overweight or leading an inactive lifestyle. In fact, some are present from childhood.

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:

  • being overweight
  • a family history of diabetes
  • having a high-density lipoprotein (HDL) cholesterol level lower than 40 mg/dL or 50 mg/dL
  • a history of high blood pressure
  • having gestational diabetes or giving birth to a child with a birth weight of more than 9 pounds
  • a history of polycystic ovary syndrome (PCOS)
  • being of African-American, Native American, Latin American, or Asian-Pacific Islander descent
  • being more than 45 years of age
  • having a sedentary lifestyle

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:

  • 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.
  • The body tries to make extra insulin to process the excess blood glucose.
  • The pancreas cannot keep up with the increased demands, and the excess blood sugar starts to circulate in the blood, causing damage.
  • 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.

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.

Exercise and diet tips

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.

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

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

  • Eating a diet high in fresh, nutritious foods, including whole grains, fruits, vegetables, lean proteins, low-fat dairy, and healthy fat sources, such as nuts.
  • Avoiding high-sugar foods that provide empty calories, or calories that do not have other nutritional benefits, such as sweetened sodas, fried foods, and high-sugar desserts.
  • Refraining from drinking excessive amounts of alcohol or keeping intake to less than one drink a day for women or two drinks a day for men.
  • Engaging in at least 30 minutes of exercise a day on at least 5 days of the week, such as walking, aerobics, riding a bike, or swimming.
  • Recognizing signs of low blood sugar when exercising, including dizziness, confusion, weakness, and profuse sweating.

Slow, steady weight loss goals are more likely to help a person retain long-term benefits.

Using insulin

People with type I diabetes and some people with type 2 diabetes may need to inject or inhale insulin to keep their blood sugar levels from becoming too high.

Various types of insulin are available, and most are grouped by how long their effect lasts. There are rapid, regular, intermediate, and long-acting insulins.

Some people will use a long-acting insulin injection to maintain consistently low blood sugar levels. Some people may use short-acting insulin or a combination of insulin types. Whatever the type, a person will usually check their blood glucose levels using a fingerstick.

Excessive insulin can cause hypoglycemia, or extremely low blood sugar, and lead to nausea, sweating, and shaking.

It is essential that people measure insulin carefully and eat a consistent diet that balances blood sugar levels as much as possible.
