Type 2 Diabetes In Children: Symptoms, Causes & Warning Signs

Can Type 2 Diabetes occur in children? Type 2 Diabetes in children is growing rapidly due to rising childhood obesity, improper diet and unhealthy lifestyle habits. Read on to know if your child is at risk for developing Type 2 Diabetes.

When we think of Type 2 Diabetes, we assume that it is a condition that is exclusive to individuals who are middle-aged. But did you know that Type 2 Diabetes can also occur in children? In this article, we will discuss the causes of Type 2 Diabetes in children, the signs to watch out for, and how to manage it effectively.




What is Type 2 Diabetes?

Type 2 Diabetes is a chronic metabolic disorder where your body is unable to utilize insulin. Insulin is a hormone produced by the beta cells in your pancreas that helps your cells take in the glucose (sugar) present in your bloodstream. In Type 2 Diabetes, your cells and tissues become insulin resistant, i.e. they are unable to respond to the insulin present in your body, which leads to high blood glucose levels.


Causes of Type 2 Diabetes in Children

The exact cause of Type 2 Diabetes in children is unclear, but it is closely linked to being overweight or obese and having a family history of Type 2 Diabetes. Being overweight can lead to insulin resistance, which causes Type 2 Diabetes.


Risk Factors for Type 2 Diabetes in Children

The following are the risk factors associated with Type 2 Diabetes in children.



Being overweight or obese can increase your child’s risk of developing Type 2 Diabetes. More specifically, having too much fat in the abdominal area can decrease insulin sensitivity in the body, which can cause Type 2 Diabetes. 


Unhealthy diet

Having an unhealthy diet that is loaded with empty carbs, added sugars, and saturated or trans fats can raise your child’s blood sugar levels, which can cause an increase in weight, along with their chances of developing Type 2 Diabetes.


Lack of physical activity

Exercise or any physical activity can help your child’s body utilize the glucose present in their bloodstream along with the glucose stored in their muscles and liver. This lowers their blood sugar levels and helps their body in burning fat. A lack of physical activity leads to excess blood glucose being converted to fat, which can cause weight gain and increase insulin resistance in your child’s body. 


Family history

Having close family members like parents, grandparents, or siblings who have Type 2 Diabetes can increase your child’s risk of developing this condition.


Gestational diabetes in the mother

Being born to a mother who had gestational diabetes can make your child more prone to develop Type 2 Diabetes.


Symptoms and Warning Signs of Type 2 Diabetes in Children

The signs and symptoms of Type 2 Diabetes in children or teens may be mild or unnoticeable at first. However, the following symptoms of Type 2 Diabetes may develop over time:


Diagnosis of Type 2 Diabetes in Children

Appropriate and timely diagnosis plays a crucial role in the management of diabetes in kids. Diagnosis may include tests such as:


Hemoglobin A1C (HbA1c) Test 

This test helps determine your child’s average blood glucose levels for the past 2 to 3 months. Having an HbA1c level of 6.5 % or higher is considered a diagnostic criterion for diabetes.


Fasting Blood Sugar (FBS) Test

This test measures your child’s blood sugar levels after fasting for at least 8 hours. A blood glucose level of 126 mg/dL or higher indicates that your child may have diabetes.


Random Blood Sugar (RBS) Test 

This test is done at any time regardless of when your child had their last meal. A blood glucose level of 200 mg/dL or higher indicates that your child may have diabetes.


Treatment of Type 2 Diabetes in Children

The treatment of Type 2 Diabetes in children is similar to the treatment of diabetes in adults. The treatment approaches might include a combination of the following:

  • A healthy and balanced diet
  • Regular exercise
  • Losing excess weight
  • Frequent monitoring of blood glucose levels
  • Oral medications/ insulin injections 


Potential Complications of Type 2 Diabetes in Children

Children with Type 2 Diabetes might be at risk of developing complications such as high cholesterol levels, high blood pressure, depression, eating disorders, etc. Serious complications that may occur later in life due to uncontrolled blood glucose levels include:


These complications can be prevented or delayed with treatment and maintaining normal blood glucose levels.


Prevention of Type 2 Diabetes in Children

Type 2 Diabetes is a lifestyle disorder that can be prevented by maintaining a healthy and active lifestyle. It can be prevented in children with the following measures:

  • Being physically active and exercising regularly
  • Eating a well-balanced diet
  • Maintaining a healthy weight
  • Learning to manage stress
