After Cardiac Bypass Surgery

How long does it take to recover after cardiac bypass surgery?

Recovering from cardiac bypass surgery generally takes most people anywhere from 6-8 weeks to 3 months. Before you leave hospital, you’ll be given detailed instructions for exercise, medications, follow up appointments, ongoing wound care and resuming normal activities.

You’ll also be encouraged to book into a cardiac rehabilitation program, which is a dedicated program that helps to support you, every step of the way, as you heal, recover and get back to your everyday routine.

It’s very common to feel ‘different’ for a short while after your cardiac bypass surgery. To hear from our social worker about some of the emotional changes you may experience during your recovery, watch this short video.

What should I eat after cardiac bypass surgery?

After your cardiac bypass surgery, you’ll need to focus on eating a healthy diet. This will help your body to heal, reduce your risk of complications and enable you to recover well. Many studies have shown that a diet rich in fruits, vegetables, wholegrains, nuts and seeds can reduce your risk of heart disease.

You may notice that you have a poor appetite and find that food has lost its flavour. Your sense of smell may change and you may also experience a strange metallic taste in your mouth. This can be caused by the operation or your medication and can take 3 months to fully recover. Try to eat small amounts of food often.

A healthy diet provides your body with plenty of heart-protective nutrients - like vitamins, minerals, antioxidants and dietary fibre. Ideally, your diet should include:

  • Meat - and/or meat alternatives such as eggs, tofu, legumes and nuts 
  • Fish - 2 serves of oily fish per week such as salmon, mackerel or sardines will help you get plenty of heart healthy omega-3 fats
  • Wholegrains - good wholegrain choices include wholemeal or wholegrain bread or crackers, brown rice, wholemeal pasta, quinoa, freekah, barley, rye, rolled oats, polenta and couscous
  • Dairy - preferably low fat 
  • Healthy fats - a small amount of healthy fats and oils from nuts, seeds, avocado and oily fish
  • Water - avoid sugary soft drinks and drink alcohol only in moderation 

Aim to consume 2 serves of fruit, 5 serves of vegetables and 4 or more serves of wholegrains - depending on your energy needs. Some other tips to help you eat well include:

  • Reduce your salt intake - use as little salt as possible when cooking as this will help to lower your blood pressure and help prevent fluid retention
  • Avoid sugary foods - these are often eaten in place of healthy foods and can contribute to weight gain

What medications will I need to take after cardiac bypass surgery?

After cardiac bypass surgery you’ll need to take pain medications, as you can feel wound and muscle pain for a few weeks (if the pain persists beyond a few weeks, see your doctor). You can learn more about different types of chest pain here. You’ll also be given medicines to lower your risk of complications and a further cardiac event. 

Medications work best when you’re being healthy in all areas of your life - for example, exercising, quitting smoking and eating a healthy diet. Everyone has individual requirements for medications, and you’ll be given a personalised medicine plan that’s right for you. 

You can learn more from our pharmacist about the medications you may need to take by watching this video below. If you have any questions about the medication you’re taking, speak to your doctor or pharmacist. 

How do I reduce my risk of further heart problems after cardiac bypass surgery?

After your cardiac bypass surgery, it’s very important to take steps to reduce your risk of having another heart problem or needing more heart surgery. Some of the heart disease risk factors that you may be able to control include:

The good news is that complications from your cardiac bypass surgery aren't common. You should see your doctor if you experience any of the following symptoms, which may signal a problem with your heart: 

  • Persistent chest pain which is not related to your wound (angina is rare, but possible)
  • Irregular heartbeat or palpitations
  • Persistent fever over 38 degrees Celsius
  • Chills
  • Rapid weight change (over 2kg in 24 hours)
  • Dizziness or fainting
  • Excessive tiredness or weakness
  • Severe shortness of breath or shortness of breath which is increasing
  • Nausea and vomiting
  • Wound infection; signs include ooze, redness or swelling
  • Weight loss or appetite change
  • A cold or sore throat

Avoiding infections is something you need to be aware of, as you may be more likely to get sick after your surgery. Visit your doctor and dentist regularly, and brush your gums with a soft toothbrush.

How do I resume my regular activities after cardiac bypass surgery?

As it takes 6-8 weeks for your breastbone to heal after cardiac bypass surgery, you need to ease back into your regular activities slowly.

Below, you can watch a video demonstrating how to look after your breastbone after cardiac surgery.


Here’s a look at when it’s safe to resume some common activities:

  • Driving – the RTA enforces no driving for 4-6 weeks, except on the advice of your doctor, as concentration, reflex time and eyesight are often affected for 6 weeks
  • Sex – sex requires about the same amount of energy as walking up two flights of stairs, and you’re generally ready to ease back into this from around week 3 (it’s normal to lose interest in sexual activity for a while; however, like other activities, you should be back to normal at 3 months)
  • Work – you can return to work related activities as soon as your concentration, confidence and physical abilities allow, and most people return to light office work from 6 weeks and heavy work at 3 months
  • Gardening – during your first week at home you’ll be able to hose the garden, and by the third week you can do a small amount of weeding and pruning. By your sixth week you can dig soft soil, and trimming hedges can be done at the eighth week 
  • Housework –start with the activities that you like to do the most, and keep it simple - light cooking, flower arranging, tidying up, dusting, washing up and clothes washing can all be started early, but delegate the heavier tasks to your family

How do I start exercising again after cardiac bypass surgery?

Exercising will help to speed up your recovery, and it’s a key component of a healthy lifestyle. Exercise increases your fitness levels, helps control blood pressure, weight and cholesterol, and keep you relaxed. Start with short and simple walks, and gradually increase length and intensity.

You can walk as much as you like as long as you feel comfortable, and daily walking - if only for a few minutes - is ideal. Here’s an example of how you might ease back into some other common forms of exercise:

  • Bowls – practice swinging the ball at six weeks, attend a roll up at eight weeks, and by three months you should be back to a full competitive game
  • Tennis –practice hitting the ball and gentle serving at six weeks, play a leisurely game of doubles at 8-10 weeks , and at 3 months you should be able to play a full competitive game
