Self care

As you have been diagnosed with type 2 diabetes, it’s especially important that you look after your physical and mental health and well-being.

Keeping healthy1-5

Staying fit and healthy and managing your blood glucose levels will make treating your diabetes easier and reduce your risk of developing future complications.
Keeping healthy can also help you to reduce your risk of developing diabetic kidney disease, or slow it down if you already have it.

Making changes to the way you live can be difficult, but even small steps towards a healthier lifestyle can really make a difference. Your healthcare team can give you information and advice, and support from people close to you can be very helpful.

  • Healthy eating – eating a balanced diet can help you maintain a healthy weight and can help keep your blood glucose at the right level
  • Regular exercise is crucial as it can help to keep your blood glucose and blood pressure at healthy levels
  • Stop smoking to reduce the risk of developing heart or kidney disease
  • Limit your alcohol – as alcohol can affect your blood glucose, avoid drinking more than the recommended daily amount and don’t drink on an empty stomach
  • Keeping well – ensure you attend any check-up appointments with your GP or diabetes nurse; you should also have the flu jab every winter
  • Check your feet regularly – diabetes can affect the blood circulation and nerves in your feet and make it more difficult for you to notice problems; view more information about foot care
  • Regular eye tests – too much glucose in the blood can damage blood vessels in the eye, causing sight problems or blindness; regular eye tests can help spot symptoms early and monitor any damage
  • Regular kidney function tests – you will have blood and urine tests every year as part of your diabetes review to see how well your kidneys are working; these can spot problems early so they can be treated
  • Follow the ‘sick day rules’ – if you feel unwell
Sick day rules6-11

If you feel unwell, your blood glucose levels can be affected. Illness or infections can raise your blood glucose, or if you are sick or have diarrhoea, your blood glucose can drop. You can also become dehydrated, which can cause serious side-effects, especially when your blood sugar levels are high.

The best way to prevent foot problems, including amputation, and other severe diabetes complications is to manage your blood glucose.
Checking your feet regularly can help identify and treat any problems quickly and reduce the chance of amputation. Everyone with diabetes should have foot check-ups as part of their regular care routine. You can also help reduce the chance of problems with your feet by following a simple foot care routine at home.

If you find it difficult to reach your feet, or you don’t feel you can see your feet well enough to check them properly, ask a family member, friend or carer to check them for you.

What can I do to help reduce my risk of side-effects?

Preventing genital infections

One of the common side-effects of Invokana for both men and women is genital infections, for example vaginal yeast infection. There are some things you can do to help prevent these infections from occurring:

  • Wash the area with warm water and avoid using perfumed soaps, shower gels, or douches
  • Avoid using latex condoms, spermicidal creams or lubricants if they irritate your genital area
  • Avoid wearing tight-fitting underwear
  • Wear cotton underwear and loose-fitting trousers and skirts
  • Wash your hands thoroughly after going to the toilet

If you do get an infection, treatment is available at pharmacies or from your doctor.

Preventing dehydration

It is important to stay hydrated. You can prevent dehydration by drinking plenty of fluids through the day; you should aim to drink about six to eight glasses of fluid every day.15
