In Diabetic Ketoacidosis Dka Do We Administer Fluids Or
Overview
Diabetic ketoacidosis (DKA) is a serious problem that can happen when your body does not have enough of the hormone that moves sugar from your blood into your cells. Without that hormone, sugar builds up in the blood and your body starts burning fat for fuel instead. Burning fat makes acids called ketones (say: KEE-tones). Too many ketones turn your blood acidic, and your body loses a lot of water through fast breathing and frequent peeing. DKA is a medical emergency that needs hospital treatment. The simple answer to the question 'do we give fluids or hormone treatment?' is: both — and fluids usually come first.
Key facts
- DKA is treated in hospital with fluids given through a drip, hormone treatment given through a drip, and replacement of body salts. Fluids are usually started first because severe dehydration is the most immediate danger.
- DKA is a medical emergency. If you think you or someone else has it, call your local emergency number right away.
- DKA can happen even when blood sugar is not extremely high, so feeling very unwell with vomiting and fast breathing always needs urgent medical advice.
DKA is the most common serious emergency linked to diabetes. It is much more common in people with type 1 diabetes, but it can also happen in people with type 2 diabetes, especially during severe illness.
It can affect anyone with diabetes, at any age. It is most often seen in children and young adults with type 1 diabetes, in people who are unwell with an infection, and in people who have missed doses of their diabetes hormone treatment. Older adults can also develop it with less obvious warning signs.
Symptoms
- Fast, deep or laboured breathing
- Being very drowsy, hard to wake, or unconscious
- Confusion, agitation, or strange behaviour
- Vomiting and unable to keep any fluids down
- A fruity smell on the breath together with feeling very unwell
- Blood sugar very high with high ketones and any of the symptoms above
- ⚠Blood sugar staying high after your usual care
- ⚠Moderate or high ketone levels on a home test
- ⚠Vomiting or diarrhoea while on diabetes treatment
- ⚠An infection, fever, or injury that is making blood sugar harder to control
- ⚠Feeling unwell and unsure what to do — contact your diabetes team or an urgent health service straight away
Common symptoms
- Very thirsty and needing to pee much more than usual
- High blood sugar readings that do not come down with usual care
- Feeling or being sick, and tummy pain
- A fruity or pear-drop smell on the breath
- Fast, deep breathing
- Dry mouth, dry skin, and feeling very weak or sleepy
- Feeling confused or muddled
- Muscle aches and headaches
Symptoms in children
- Wetting the bed again after being dry at night
- Tummy ache and vomiting that can look like a stomach bug
- Fast or heavy breathing
- Unusual sleepiness, grumpiness, or being hard to wake
- Fruity-smelling breath
- In a child not yet diagnosed, this can be the first sign of type 1 diabetes
Symptoms in older adults
- Confusion or sudden change in behaviour, which may be the main sign
- Feeling very tired, weak, or unsteady on the feet
- Not drinking enough, leading to heavy dehydration
- Blood sugar that may be only moderately raised, even when the person is very unwell
- Vomiting and tummy pain that can be mistaken for another illness
Causes
Main causes
- Not having enough of the hormone that controls blood sugar — for example, missed doses, a broken pump, or a blocked cannula
- Being diagnosed with type 1 diabetes for the first time, before treatment has started
- Infection or illness such as a cold, flu, urine infection, or chest infection — the body needs more hormone when it is fighting infection
- Severe dehydration or not eating and drinking when unwell
- A heart attack, stroke, or serious injury, which puts great stress on the body
- Some medicines can raise the risk, including certain diabetes tablets and steroids — ask your pharmacist or doctor about your own medicines
- Alcohol or drug use, and extreme dieting or fasting
Risk factors
- Living with type 1 diabetes, especially as a young person
- Previous episodes of DKA — having it once makes it more likely again
- Being unwell with an infection
- Not having a clear sick-day plan or not knowing how to check ketones
- Difficulty affording or getting supplies, or trouble managing treatment
- Mental health difficulties, eating difficulties, or problems remembering medication
- Pregnancy with diabetes
- Being an older adult living alone with less support
When to see a doctor
See a doctor urgently if:
- You have diabetes and are vomiting, have tummy pain, and cannot keep fluids down
- Your home ketone test shows moderate or high levels
- Your blood sugar stays high after your usual care and you feel unwell
- Your breath smells fruity, or you are breathing fast
- You have an infection with a fever and your blood sugar is rising
- Your diabetes hormone treatment has been interrupted — for example, a pump problem or a missed dose — and you feel unwell
Book a routine appointment if:
- You want to make or update a sick-day plan before you become unwell
- You are unsure how to check ketones or what your results mean
- You have had DKA before and want to talk about how to prevent it
- You are struggling to afford or collect your diabetes supplies
- You feel low, anxious, or worn down by managing diabetes
Diagnosis
DKA is diagnosed in hospital, usually in an emergency department. A doctor will ask about your symptoms, check your breathing and hydration, and take blood and urine tests. The tests look for high blood sugar, high ketones, acidic blood, and changes in body salts. Treatment usually starts straight away while results are coming back — doctors do not wait for every result before giving fluids.
Tests that may be done
- A finger-prick or blood sugar test
- A blood ketone test, or a urine ketone test
- Blood tests to measure acidity and body salts such as potassium and sodium
- Kidney function tests
- A urine test or other tests to look for infection
- A heart tracing (ECG) if body salt levels are abnormal
- Chest X-ray or other scans if an infection or other trigger is suspected
What to expect at your appointment
You will usually be looked after in a hospital ward, a high-dependency unit, or an intensive care unit. Nurses will check your blood sugar, ketones, and observations often — sometimes every hour at first. You will have a drip in your arm, and you may have a tube in your nose or mouth to help if you are very drowsy. Most people start feeling much better within a day, but you may stay in hospital for a few days while the team finds and treats the cause.
Treatment
DKA treatment happens in hospital and has three main parts: replacing the water your body has lost, gently bringing your blood sugar down with hormone treatment, and correcting your body salts. Fluids are usually given first, because severe dehydration is the most urgent danger. Hormone treatment is then started carefully, alongside close monitoring, because giving it too quickly can cause problems. The team also looks for and treats whatever triggered the DKA, such as an infection.
Self-care at home
- Once you are home, follow your diabetes team's plan closely and keep all follow-up appointments
- Ask for a written sick-day plan and keep it somewhere you can find it easily
- Keep ketone test strips or a ketone meter at home and check them when you are unwell
- Drink plenty of sugar-free fluids when you are ill, and keep eating small amounts if you can
- Never stop your diabetes hormone treatment because you are not eating — ask your team first
- Check your feet, skin, and injection or pump sites for problems
- Wear or carry medical ID so others know you have diabetes in an emergency
Medical treatments
In hospital, treatment is given through a drip into a vein. The first step is usually a steady flow of fluids to rehydrate the body and help the kidneys and circulation. Next, the care team gives the hormone your body is missing, through a drip, in a carefully controlled amount. They also replace body salts, especially potassium, which can drop dangerously low during treatment. Throughout, the team checks blood sugar, ketones, salts, and heart rhythm regularly, adjusting treatment as things change. They also treat the trigger, such as antibiotics for an infection. Nobody should try to manage suspected DKA at home — it needs hospital care.
When is surgery considered?
Surgery is not a treatment for DKA. However, an operation or a serious injury can trigger DKA, so hospital teams take extra care with fluids and hormone treatment around surgery for people with diabetes.
Living with this condition
Living well with diabetes is mostly about routine and planning. Check your blood sugar as your team advises, keep your supplies stocked, and know what to do on days when you are ill. Have a sick-day plan on paper and on your phone. Tell the people you live or work with what to look out for, and make sure they know to call emergency services if you become very drowsy or confused.
Lifestyle tips
- Keep a simple kit ready at home: ketone tests, extra fluids, and your team's contact details
- Carry fast-acting sugar and medical ID every day
- Plan ahead for travel, exams, and stressful events — these can raise blood sugar
- Avoid skipping meals or doses without advice
- Limit alcohol, and never drink heavily when your blood sugar is high or you feel unwell
- Get your flu and other recommended vaccinations — infections are a common trigger for DKA
Diet and exercise
There is no single 'diabetes diet'. Eating regular meals with vegetables, beans, whole grains, and lean protein helps keep blood sugar steadier. A dietitian can help you build a plan that fits your life and culture. Activity is good for almost everyone with diabetes — it helps your body use sugar better. Check your blood sugar before, during, and after exercise, keep a snack nearby, and drink water. When you are ill or your ketones are high, rest and fluids matter more than exercise. If you use a pump or hormone injections, ask your team how to adjust for exercise.
Mental health and emotional wellbeing
Diabetes is a full-time job, and it is completely normal to feel tired, worried, or fed up with it. Some people feel anxious about low or high blood sugar, or blame themselves after a DKA episode. This is not a failure — DKA can happen even when you do everything right. Talking about how you feel helps. Tell your diabetes team, and ask about emotional or psychological support. If you ever feel you cannot cope or have thoughts of harming yourself, contact your local emergency number or a crisis support service in your area straight away, and reach out to someone you trust.
Prevention
Most episodes of DKA can be prevented, though not every one. The key is to act early when you are ill or your blood sugar is rising. Check ketones when you feel unwell, keep taking your diabetes treatment, drink plenty of fluids, and contact your team early rather than waiting. Make sure you always have supplies and know your sick-day plan. If you have had DKA before, ask your team for extra support — a prevention plan lowers the chance of it happening again.
Vaccines
Infections are a common trigger for DKA, so keeping up with recommended vaccinations — including flu and other routine vaccines your local health service advises — helps protect you. Ask your doctor or pharmacist which ones are right for you.
Screening programmes
Regular diabetes reviews check your blood sugar control, blood pressure, kidneys, eyes, and feet. These checks help spot problems early and lower your risk of emergencies. Ask your team how often you should be reviewed.
Complications
If left untreated
- Severe dehydration and shock, when the body's circulation starts to fail
- Dangerously low potassium, which can affect the heart rhythm
- Swelling of the brain, which is uncommon but more likely in children
- Kidney injury
- Fluid building up in the lungs
- Blood clots
- Coma and death if not treated quickly
Long-term outlook
The outlook is good. With prompt hospital treatment, most people recover fully and go home within a few days. Many people never have a second episode. If you have had DKA, your team can help you build a plan to reduce the chance of it happening again — and knowing the warning signs means you can act fast next time.
