High blood pressure dietitian

High blood pressure often has no symptoms, and what you eat can help. Our dietitians help you cut back on salt and build an eating pattern you can keep.

Understanding the condition

High blood pressure (hypertension) means the force of blood against your artery walls is consistently high, usually above 140/90 mmHg when measured.1 It affects about one in three Australian adults and usually causes no symptoms, so regular checks matter.1 Over time it puts extra pressure on your blood vessels and is a major risk factor for heart disease and stroke.2

Food is a big part of managing it, alongside any medicines your doctor prescribes. The Heart Foundation recommends no more than 5 grams of salt a day, about 2000 mg of sodium, and the average Australian eats nearly double that.2 A dietitian helps you find hidden salt, swap it for herbs and spices, and eat a DASH style pattern rich in vegetables, fruit, wholegrains, reduced-fat dairy, nuts and seeds.3 Limiting alcohol and being active also help.1 The Australian guideline places a healthy eating pattern low in saturated fat alongside medicines when your overall risk is higher.4

What to look out for, and how we help

Symptoms are a guide, not a diagnosis. Your GP confirms the diagnosis; our team helps you manage it day to day.

What you might notice

  • Most people have no symptoms, so high blood pressure is usually found at a check-up
  • Very high blood pressure may cause headaches, dizziness, nosebleeds or vision problems
  • Often found alongside other risk factors such as diabetes, high cholesterol or a family history of heart disease
  • Australian guidelines recommend heart disease risk assessment from age 45, from 35 for people living with diabetes and from 30 for Aboriginal and Torres Strait Islander people
  • Regular blood pressure checks are the only reliable way to know your numbers
  • Red flag: call 000 if you have a severe headache, vomiting, vision problems, confusion, a seizure, chest pain or shortness of breath that comes on quickly, especially with very high blood pressure.

How our team helps

  • Assessment of what you eat, your blood pressure readings, your medicines and your medical history
  • A personalised eating plan using a DASH style pattern, with practical ways to reduce salt and include potassium-rich foods where suitable
  • Label reading and shopping skills, including finding hidden salt in sauces, breads and packaged foods
  • Cooking demonstrations that show how to build flavour with herbs and spices
  • Advice on alcohol and food choices that fit with your activity and weight goals
  • Review appointments, with coordination with your GP, pharmacist and exercise physiologist

Common questions

How much salt should I eat with high blood pressure?
+

The Heart Foundation recommends adults have no more than 5 grams of salt a day, which is about 2000 mg of sodium. Most Australians eat far more, mostly from packaged foods, takeaway and sauces. A dietitian helps you find and swap hidden salt.

What is the DASH diet?
+

DASH stands for Dietary Approaches to Stop Hypertension. It is an eating pattern rich in vegetables, fruit, wholegrains, reduced-fat dairy, nuts and seeds, and lower in salt and saturated fat. We adapt it to your tastes, budget and cultural food preferences.

Can I lower my blood pressure with food instead of medicine?
+

Eating changes help and sit alongside medicines rather than replace them. Your doctor decides whether you need medicine. Please do not stop or change a blood pressure medicine without talking to your doctor or pharmacist first.

Should I eat more potassium-rich foods?
+

Vegetables and fruit contain potassium and are part of DASH style eating. If you also have kidney disease or take certain medicines, potassium advice can differ, so we check with your doctor before changing your intake.

Do I need a referral to see a dietitian for high blood pressure?
+

No referral is needed for private appointments. A Medicare rebate needs a GP Chronic Condition Management Plan and a GP referral, and applies to up to five eligible allied health services a calendar year. Private health extras, NDIS or DVA funding may also apply, so ask us when you book.

Not sure where to start?

Tell us what is going on and we will point you to the right discipline, or to more than one. Most people start with a single appointment and leave with a plan the rest of the team can see.
