Diabetes often goes undetected in children because symptoms may be absent, mild or misinterpreted as the flu.

The following indicators may be seen with type 1 diabetes or type 2 diabetes:

• Drowsiness, fatigue or lack of energy.
  
  
• Extreme thirst (polydipsia).
  
  
• Bedwetting and polyuria (increased urination).
  
  
• Unexplained weight loss.
  
  
• Increased appetite (polyphagia).
  
  
• Obesity. Obesity often accompanies the insulin resistance that can lead to type 2.
  
  
• High glucose (hyperglycemia).
  
  
• Frequent infections.
  
  
• Slow healing of sores.
  
  
• Itching (pruritus).
  
  
• Vision changes.
  
  
• Mood changes and depression.
  
  
• Dizziness.
  
  
• Sweet, fruity-smelling breath. This may indicate ketosis. High levels of a waste product called ketones can form in the blood when the body uses stored fat for energy rather than glucose (blood sugar).
  
  
• Ketoacidosis. A dangerous condition involving ketosis and severe hyperglycemia. Some children are diagnosed with diabetes through being hospitalized with ketoacidosis.
  
  
• Hyperosmolar hyperglycemic nonketonic syndrome (HHNS). Dangerously high glucose along with dehydration. Some children are diagnosed with diabetes through being hospitalized with HHNS.
  
  
• Insulin resistance. The body’s impaired response to insulin may be an early sign of diabetes.
  
  
• Acanthosis nigricans. A skin condition marked by velvety dark patches, usually on the armpits, back of the neck or thighs. It is generally a sign of high levels of insulin (hyperinsulinemia).
  
  
• Vaginitis. A fungal infection of the vagina that is common in girls with diabetes.
  
  
• Polycystic ovarian syndrome (PCOS). A condition seen in girls with insulin resistance or type 2 diabetes, irregular or absent menstrual periods, increased hair on the face or body and high levels of male hormoneshormone (androgens).
