High Blood Pressure or Hypertension

Naturopathic Doctors

Our naturopathic doctors can help to naturally lower your blood pressure without medications using the scientifically validated diet, lifestyle and supplement treatments listed below.

Diet for high blood pressure

Our naturopaths can recommend dietary changes to help with hypertension, strengthen the heart and blood vessels and support the cardiovascular system.

Exercise for hypertension

Our naturopathic doctors can advise on the best exercise to lower blood pressure

Herbs, Vitamins & Minerals

Supplements can be used to naturally lower blood pressure by addressing the underlying cause of why you have hypertension:

  1. Arteriosclerosis – hardening of the arteries due to build up of plaque on the walls of the artery
  2. Kidney disease
  3. Stress/tension

Acupuncture, TCM and High Blood Pressure

Our TCM and acupuncture expert, Joy Walraven, can help naturally strengthen the cardiovascular system and lower blood pressure with acupuncture and Traditional Chinese herbs.

Registered Massage Therapy

If blood pressure is high due to stress or tension, massage therapy is an excellent way to reduce stress, increase parasympathetic nervous system activity and promote relaxation and overall wellness.

Low Blood Pressure

Do you get dizzy or light-headed if you stand up too quickly?  That sensation you feel is likely from your blood pressure dropping.  It shouldn’t.  As you stand up your blood pressure should naturally come up to maintain adequate blood flow to your brain.

The body’s mechanisms to increase low blood pressure include increasing heart rate and contraction, constricting blood vessels and retaining water.  Many of these tools are regulated by the adrenal glands, small glands that sit on top of the kidneys.  Poorly functioning adrenal glands can negatively influence blood pressure.  The severe version of this is termed Addison’s disease, however, there is a spectrum of adrenal dysfunction that is less severe than Addison’s.  Other causes of low blood pressure include kidney disease, heart disease, blood loss, shock, dehydration and medication side effects.

Our naturopathic doctors can help regulate both low blood pressure and high blood pressure.
