High Blood Pressure or Hypertension
The causes of high blood pressure include:
- Atherosclerosis. This is the deposition of fatty materials on the lining of your arteries. Therefore, it “clogs” your arteries, and narrows the space for blood to travel through. If the same volume of blood is trying to squeeze through a smaller space, it increases the pressure in the arteries.
- Damage to the lining of your arteries. Fatty deposits on the lining of your arteries may be due to damage to the endothelial lining. Risk factors for high blood pressure like smoking, caffeine, and alcohol contribute to atherosclerotic plaques that then block your arteries.
- Aging. As we age, our ability to make healthy collagen declines. The walls of your arteries are made up of collagen. As collagen production decreases, the arterial walls get weaker. This leads to even more arterial plaque build-up.
- Kidney disease. The kidneys are responsible for filtering urine out of your blood. If your kidneys can’t filter out fluid effectively, the water stays in your bloodstream. The added volume causes pressure to build in your arteries.
Risk Factors for Hypertension
There are a number of risk factors that increase your chances of having hypertension. We can help you tackle most of them:
- Being overweight or obesity
- Lack of physical activity
- Excess salt intake
- Excessive caffeine intake
- Increased alcohol intake
- High stress
- Being older in age
- Family history of hypertension
- Kidney, adrenal and thyroid disorders
- Sleep apnea

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.
Your body’s mechanisms to increase low blood pressure include increasing your heart rate, constricting your blood vessels and retaining water. Many of these tools are regulated by your adrenal glands. These small glands sit on top of your kidneys. Poorly working adrenal glands can negatively influence both high and low blood pressure. The severe version of under-working adrenals is termed Addison’s disease. However, there is a range of low adrenal function (more accurately deemed HPA axis 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. We can monitor your blood pressure readings to ensure your success.

Bae S, Hong YC. Exposure to bisphenol A from drinking canned beverages increases blood pressure: a randomized crossover trial. Hypertension. 2015; 65(2):313-9.
● This study measured the effects of drinking beverages from BPA containing cans versus glass bottles. Researchers found that after drinking from the cans urinary BPA levels increased by more than 1600% compared to drinking from glass bottles. Systolic blood pressure increased by 4.5 mmHg after consuming two canned beverages compared with glass beverages.

● This large prospective cohort study in an Asian population found an inverse U-shaped association between coffee intake and risk of hypertension. Drinking one cup of coffee per day was associated with increased risk. However, less than 1 cup of coffee per week or greater than 3 cups of coffee per day was associated with a decreased risk of hypertension.
