If you have type 2 diabetes or have been told that you may get it in the future (prediabetes), lifestyle changes can help lower your blood glucose (sugar) levels. This can help to manage diabetes and possibly avoid having to take medicine.
Lifestyle changes can sometimes lower your blood glucose to a normal level and stop diabetes (remission).
What you can do to make lifestyle changes:
try to eat a healthy diet including fruit, vegetables, wholegrain foods such as wholemeal bread and oats, and pulses such as chickpeas and lentils
improve your diet slowly if you're finding it difficult – a small change every week can make it easier
talk to a GP or diabetes nurse if you're finding it hard to change your diet as they may be able to find support in your local area
try to spend at least 2.5 hours (across the whole week) either walking or doing another activity that leaves you out of breath
try to lose weight if you've been told you're overweight
stop smoking – having diabetes increases the harmful effects of smoking
try to limit how much alcohol you drink
have regular dental check-ups to help prevent gum disease
do not each too much processed foods with lots of salt and sugar – this may include things like bacon, chips, cheese, sweets and biscuits
do not change to a very strict, low-calorie diet without talking to a health professional first – this type of diet may not be suitable if you're taking insulin or other diabetes medicine
Children with type 2 diabetes will be under specialist care.
If you have prediabetes and are at risk of developing type 2 diabetes, you may be eligible for an NHS programme that can help you.
Speak to your doctor or nurse about the NHS:
If you need medicine, you'll usually be offered metformin, which is one of a few medicines used to treat type 2 diabetes.
If you have another health problem, or metformin alone does not lower your blood glucose level, you may need to take another medicine with metformin, or change to a different diabetes medicine.
If metformin, or other diabetes medicines, do not help, you may need to take insulin. It's usually used to treat type 1 diabetes, but it can be used to treat type 2 diabetes, as well.
You may need to take insulin a few times a day, either by injection or through a pump. This will help keep your blood glucose levels within a normal range.
You'll be told how much to take and when to take it. Taking too much insulin can cause your blood glucose levels to go too low. This is known as hypoglycaemia or having a "hypo".
If you feel ill, such as vomiting, diarrhoea or a very high temperature, while you're taking diabetes medicine, speak to a doctor or a member of your healthcare team. They may tell you to stop taking your medicine temporarily, until you feel better. Do not stop taking your medicine unless your healthcare professional or doctor tells you to.
You can call 111 or get help from 111 online.
If you have type 2 diabetes, you'll need check-ups to make sure your treatment is working, and your condition is being managed.
These include:
You or your child (aged 12 years and over) will also be offered diabetic eye screening when you're diagnosed, and reviewed every 1 or 2 years as part of the NHS diabetic retinopathy screening programme.
Managing type 2 diabetes may also involve making other changes, such as:
If you have health problems caused by type 2 diabetes or you get hypos (a drop in blood glucose levels that can cause dizziness), you may need to contact the Driving and Vehicle Licensing Agency (DVLA).
If you're thinking of having a baby, and have type 2 diabetes, it's important to plan your pregnancy as soon as possible. This usually means:
If you have type 2 diabetes, talk to a doctor about the best contraception to use and how to take or use it. These may include the combined pill, progestogen-only pill or contraception inserted into the womb (uterus).
