Type 1 diabetes is a long-term condition in which the pancreas makes little or no insulin. It can start in childhood or adolescence. With timely diagnosis, insulin treatment, glucose monitoring and ongoing support from a qualified healthcare team, children with Type 1 diabetes can learn, play, take part in activities and grow.
This page explains common warning signs, how Type 1 diabetes is diagnosed, the role of insulin, and practical points families can discuss with their child’s doctor. It is general health information and does not replace an assessment of your child.
The short version
Type 1 diabetes is an autoimmune condition. The body’s immune system mistakenly attacks the insulin-producing beta cells in the pancreas. Insulin moves glucose from the blood into the body’s cells for energy. Without enough insulin, glucose builds up in the blood.
It is not caused by eating sweets, and nothing a parent did or did not do causes it. It is different from Type 2 diabetes. There is currently no cure, and in most children it cannot be prevented. It can be managed with insulin, glucose monitoring and regular follow-up.
Possible symptoms:
Symptoms can build up over days or weeks and can become serious quickly. They can be mistaken for other illnesses. If your child has these symptoms, see a doctor the same day. A blood glucose test can be done quickly, and the doctor will decide which other tests are needed.
When is it an emergency?
Go to the nearest hospital emergency department immediately if your child has possible diabetes symptoms along with vomiting, stomach pain, fast or deep breathing, fruity or sweet-smelling breath, unusual sleepiness, confusion or collapse. These can be signs of diabetic ketoacidosis (DKA), a life-threatening emergency. Do not wait for a routine appointment.
Diagnosis is based on your child’s symptoms, an examination and blood tests. A blood glucose test is usually the first step. Depending on the situation, the doctor may also advise ketone testing, HbA1c and other tests, including antibody tests, to help confirm the type of diabetes. If a child is very unwell or DKA is suspected, hospital care comes first, before any routine testing.
Insulin. Children with Type 1 diabetes need insulin. The diabetes care team sets the plan for the individual child and teaches caregivers how to give insulin safely. Never start, stop or change insulin doses without medical advice.
Glucose monitoring. Finger-prick meters and, where suitable, continuous glucose monitoring (CGM) show glucose patterns and help guide treatment. Ask your child’s doctor which option suits your child.
Food and activity. Children need balanced meals and regular, age-appropriate activity. Families learn how food, exercise, illness and insulin affect glucose levels. Do not put a child on a restrictive diet unless the doctor has advised it.
Low blood glucose (hypoglycaemia). Ask for a written plan for recognising and treating low glucose at home, at school and during sport. Ask the care team whether emergency glucagon is needed. If a child is unconscious, having a seizure or cannot swallow safely, call for emergency help.
Illness and sick days. Glucose can rise during illness even when a child is eating less. Ask for a sick-day plan, and do not stop insulin without medical advice.
School and emotional wellbeing. A written school care plan, trained adults, access to prescribed supplies and age-appropriate involvement help a child take part safely. Emotional support matters for both the child and the family.
Follow-up. Regular reviews look at glucose patterns, growth, nutrition, insulin needs and general wellbeing. How often depends on the child.
