How can I reduce my high blood pressure?

Hypertension or high blood pressure is a condition that needs to be managed to reduce the risk of developing heart disease. You can be proactive in reducing your blood pressure by making a few diet and lifestyle changes.

Here is an overview of the changes we recommend you make to reduce your blood pressure and your risk of developing heart disease.

1. Exercise – Get Moving

Studies have shown that regular aerobic exercise lowers daytime blood pressure by 3.2mmHg and 2.7mmHg respectively1. The exercise you do depends on your current fitness, age and other chronic conditions you may have. It is important to talk to your doctor before starting regular exercise to make sure you are not putting yourself at risk of having a cardiac event.

The important message here is start slow and to your ability and build up the amount of exercise you can do once your fitness levels improve. And remember, any physical activity is better than none.

2. Weight Loss

Staying a healthy weight reduces your overall risk of developing heart disease. If you are overweight losing as little as 2kg to 5kg can have a meaningful reduction in blood pressure.3,4 It is important to set achievable goals and consider seeing a dietician to help you achieve those goals.

3. Dietary changes

Consider the DASH diet (Dietary Approaches to Stop Hypertension), it is designed to reduce foods in your diet that exacerbate high blood pressure, such as excessive salt and saturated fats; and encourages more of the foods that have been shown to lower blood pressure such as vegetables, fruits and whole grains.

Aim for between 4 to 6g of salt per day (approx. one teaspoon). To do this, choose low salt products (less than 120mg/100g – check the label) and reduce the amount of processed and takeaway foods in your diet as these usually contain high amounts of salt.

4. Smoking cessation

On average a smoker’s life expectancy is up to 10 years less than a non-smoker with 60% of smokers dying prematurely from a smoking related disease. Smoking cessation has been shown to reduce blood pressure and overall heart disease risk5.

Talk to your GP about giving up smoking as there are Medicare-covered options and medications to help you quit and battle the cravings.

Consider using dedicated services such as Quitline (13QUIT) for additional support and information.

5. Alcohol intake

More than 2 standard drinks (men) and 1 standard drink (women) can cause immediate increase in blood pressure and, if consumed regularly, increases your risk of developing hypertension.6,7

Factor in alcohol free days or give up the booze entirely to reduce your risk of developing high blood pressure.

For more information regarding what you can do to lower your blood pressure and reduce your risk of developing heart disease, talk to your doctor about strategies that will best suit you and your lifestyle.
