Medical support for people with Down's syndrome

People with Down's syndrome are more likely to be born with problems, such as a heart defect. They are also more likely to get certain conditions as they get older.

If you have Down's syndrome, you should see a GP once a year for a check-up, so they can check your health.

Find out more about annual health checks.

Common health needs in people with Down's syndrome

It could help your child to see:

  • a speech and language therapist for help with speaking
  • a physiotherapist for help walking, if your child has low muscle tone
  • an optometrist or hearing specialist for help with vision and hearing
  • an occupational therapist for help with development

Heart conditions

Doctors will check your baby's heart soon after they're born.

This is because about half of all children with Down's syndrome are born with a heart condition (congenital heart disease).

If your baby has a heart condition it may get better on its own. But sometimes surgery is needed.

Speak to a children's doctor (paediatrician) to find out the next steps for your baby's care.

Help with speech, language and communication

Children with Down's syndrome might need some help speaking.

A speech and language therapist can help by:

  • checking if your child needs help with their speech
  • suggesting things you can do to help your child with their speech

Speak to a children's doctor (paediatrician), health visitor or GP who can refer your child to see a therapist.

Help with vision and hearing

People with Down's syndrome will need to have their sight and hearing regularly checked.

They may need to:

  • wear glasses
  • have a hearing aid
  • see a specialist for help if they have a condition called glue ear

Speak to a paediatrician, health visitor or GP for more information.

Getting unwell with infections

People with Down's syndrome are more likely to have a weakened immune system (the body's defence system against infections).

This means they can become seriously unwell if they get an infection like pneumonia or flu.

So it's important to have all the recommended NHS vaccinations.

It can take longer for children and adults with Down's syndrome to get better when they're unwell. They're also more likely to need medical help and may need to go to hospital more often.

It can be difficult to tell when a baby or toddler is seriously ill, but the main thing is to trust your instincts and get medical help if you're worried.

You know better than anyone else what your child is usually like, so you'll know when something is wrong.

Other health conditions

Autism

Some people with Down's syndrome can also have autism.

Common signs of autism include:

  • finding it hard to understand what others are thinking or feeling
  • getting very anxious about social situations
  • finding it hard to make friends or preferring to be on your own

Alzheimer's and dementia

Adults with Down's syndrome should have regular check-ups from about the age of 30 to look for any possible signs of dementia.

This is because they can develop dementia at a younger age.

It can help to look out for signs such as:

  • not being able to remember new things
  • getting confused more easily
  • finding it harder to understand what people are saying

These signs can often be linked to conditions other than dementia.

But if you think someone you know is showing signs of dementia encourage them to speak to a GP.
