What is diabetes?

Diabetes is a chronic condition where the body cannot produce enough insulin or properly use the insulin that is produced, or a combination of both. Insulin is a naturally occurring hormone that is produced by the beta cells in the pancreas. This hormone helps to transport glucose to the body tissues where it is stored and used for energy. Glucose is a form of sugar which is generally the main source of energy for your body. Without insulin, glucose cannot be processed, so it will stay in the bloodstream and begin to build up. Too much glucose in the blood stream can lead to serious health complications, such as nerve damage and kidney problems. People with diabetes take insulin medications to replace the natural hormone produced by the pancreas.

There are different types of diabetes, such as diabetes insipidus (DI), type 1 diabetes (T1D), type 2 diabetes (T2D), gestational diabetesmature-onset diabetes of the young (MODY) and latent autoimmune diabetes in adults (LADA) among others. However, some of these types of diabetes are more prevalent compared to others. For example, MODY is a rare condition that affects one to two percent of the population with diabetes. This rare condition is caused by a change in one gene and develops before the patient reaches the age of 25. DI is another rare type of diabetes, which, unlike other types of diabetes, it is not related to blood glucose. DI is a condition caused by an antidiuretic hormone known as vasopressin, and it is characterized by excessive thirst and urination. LADA is a form of T1D which develops later in adulthood. This condition can be mistakenly diagnosed for T2D because it too develops later in adulthood, while T1D is usually diagnosed in childhood and young adults. However, the most common type of diabetes is T2D, which occurs when there is little insulin or the body cannot effectively use the insulin that is produced.

What are the different types of diabetes?

There are many different types of diabetes, but the most common include the following:

  • Type 1 diabetes
  • Type 2 diabetes
  • Gestational diabetes

Type 1 diabetes

According to studies, type 1 diabetes accounts for 5 to 10 percent of people with diabetes. T1D is a chronic condition which occurs when the body’s immune system mistakenly destroys insulin-producing beta cells. As a result, people with T1D produce little or no insulin at all. It is not yet known what really causes the immune system to attack the beta cells. However, scientists believe that environmental and genetic factors could play a role. As more beta cells are killed off, the body cannot properly control blood glucose levels, which results in symptoms of diabetes.

T1D was previously known as juvenile diabetes since it commonly occurs in children and young adults. However, T1D tends to occur slowly in adults compared to children. Because T1D results in little or no insulin, people diagnosed with this condition require insulin through injection or with an insulin pump.

Type 2 diabetes

Type 2 diabetes occurs in the majority of people with diabetes. Studies show that 90 to 95 percent of people with diabetes have T2D. T2D was previously known as adult onset diabetes because it mainly occurs in people who are over 40 years. However, T2D can also occur in young adults and children. T2D occurs when the body cannot produce enough insulin or use it properly. This is known as insulin resistance. When people with T2D eat foods rich in sugar or carbohydrates, their bodies cannot metabolize the glucose. This leads to high blood glucose levels, which, if not treated, could damage the body’s organs. People with T2D are advised to avoid sugary foods so that they can stay healthy. However, people with T2D are generally still required to take antidiabetic medications or insulin drugs so that they can keep their blood glucose levels under control.

Gestational diabetes

Gestational diabetes is an acute condition which occurs during pregnancy. Like other types of diabetes, gestational diabetes results in high blood sugar levels, which can affect your pregnancy and the health of your baby. However, women who have gestational diabetes can still give birth to healthy babies so long as they keep their blood sugar levels under control. Pregnant women can manage their blood sugar levels by exercising regularly, eating healthy foods, and if necessary taking medication. Gestational diabetes usually disappears after giving birth, but women who had this condition are likely to develop T2D in the future.
