Fasting and high blood pressure

Many countries are finding that more and more people suffer from hypertension, more commonly known as high blood pressure. In some first world countries, experts fear that as many as half of the adults could have hypertension, stemming from poor lifestyle choices, genetics, and unprecedented levels of stress. And although we have a wide range of medication to control high blood pressure, many people are turning to natural forms of treatment to find a lasting solution, and hopefully even avoid medication altogether.

One of these natural methods that has found increasing popularity in recent years is therapeutic fasting. People abstain from eating and consume only the absolute necessary calories and nutrients from organic broths, juices, and teas. Here you will find more information on high blood pressure as well as the various fasting methods that could prove beneficial for lowering blood pressure.

What is hypertension (high blood pressure)?

The average, healthy adult should have a blood pressure of under 120 mm Hg (systolic pressure) over 80 mm Hg (diastolic pressure). When a person has reached a blood pressure of 130 systolic pressure over more than 80 diastolic pressure, they are considered to have high blood pressure.


Systolic Pressure (mm Hg)

Dialostic Pressure (mm Hg)


Normal blood pressure

Under 120

Under 80


Elevated blood pressure


Under 80


Hypertension Stage 1




Hypertension Stage 2




* Warning: If you notice that you have values close or in the stage of hypertensive crisis, contact your doctor immediately.

If high blood pressure is left untreated, it can lead to kidney and heart failure, heart attack, stroke, as well as blindness or vision problems.

Causes of high blood pressure

High blood pressure is divided into primary and secondary hypertension. Secondary hypertension, the rarest form of high blood pressure, is when the increased levels are caused by another condition or disease. Usually, if one can cure the underlying cause, the high blood pressure will also disappear.

Primary hypertension, also known as essential hypertension, is high blood pressure that presents itself without a known, underlying cause. It comprises well over 90% of high blood pressure cases. This can be due to genetics though doctors will usually attribute this to an unhealthy lifestyle, including poor diets, lack of exercise, or high levels of persisting stress.



High blood pressure treatment

The treatment for secondary hypertension will vary greatly, as the root cause of the high blood pressure will play a large role in the overall treatment.

The treatment of primary hypertension is based on using a variety of medication aimed at reducing blood pressure, as well as making meaningful and lasting lifestyle changes. The medication is used to make immediate changes to blood pressure by taking over regulating functions in the body and changing the way the body controls (excess) fluids, heart rate, arteries, as well as minerals such as sodium, potassium, and calcium.

As a part of the long-term treatment of primary hypertension, doctors will also recommend making significant lifestyle changes to diet and exercise, ultimately also asking patients to aim to lose weight. When switching to a heart-friendly diet (low sodium diet) and incorporating cardio workout routines, patients are often able to reduce medication or, in some cases, even get rid of medication altogether.

Together with a new diet and exercise regimen, doctors will often also recommend finding outlets to destress. Among the various activities they suggest, Yoga, meditation, or regular relaxing treatments are among the most popular.

Resistant hypertension

A particularly stubborn form of high blood pressure is resistant hypertension. High blood pressure is categorised as resistant when it takes 3 or more classes of high blood pressure medication, including a diuretic, to achieve acceptable blood pressure levels.

Resistant hypertension is often caused by lifestyle or medication non-compliance, meaning that patients do not adhere to their medication schedules or advised lifestyle changes.

Benefits of fasting for high blood pressure

People diagnosed with high blood pressure often find that the most difficult changes to make involve lifestyle changes, particularly when it comes to dietary changes. The days of binging on salty or sugary snacks are suddenly over and you begin to notice how much salt is hidden in many everyday foods or products. Cutting sugar-laden foods is especially important if you are expected to lose weight, but the sugar cravings tend to have a mind of their own and they don’t follow medical advice. This is where fasting can play a vital role in getting a grip of high blood pressure.

Detox those cravings

Fasting is a great way to detox your body and alleviate your system to allow organs a chance to get back to normal function. When we overeat sugary snacks, for example, we’re overtaxing our liver and pancreas, straining them and forcing them to be overworked. When you start detoxing your body with a fast, you allow your organs to finish their natural cycles and ultimately relax. In some cases, this rest allows your body to regain control of organ functions and begin to perform normally.

In taking a break from an unhealthy diet, you’re also allowing your brain to detox from sugar addictions, which will ultimately also allow you to stick to your diet and easily stick to lifestyle changes.

Medical advice

Help identify underlying causes

Certain fasting programmes, when done together with strict medical supervision, also allow doctors to get a new base level for your body and organ function, without the “interference” of food or toxins. When you strip away all of those underlying factors, it allows for more precise blood testing levels and the doctors will be able to see what happens in your body when unhealthy aspects are taken out of the health equation.

This will also help them evaluate how much of your condition is attributed to food or lifestyle choices, allowing them to also see which medication is actually necessary to control your condition.

Precautions when fasting with high blood pressure

Seek medical supervision

The most important thing when fasting with high blood pressure is to seek medical advice prior to starting. Fasting not only reduces calories from your daily consumption but might also eliminate essential nutrients and minerals required for basic functions, including those of your vital organs. These are all crucial factors in controlling your blood pressure, particularly if you are already on medication to regulate hypertension. It is imperative to ensure that you are still getting all of the right nutrients to ensure that your fast is a success and doesn’t cause unnecessary or irreversible damage.


It is also important that you seek a doctor’s advice regarding your medication. You should, of course, not quit your medication from one day to the next. It is also possible that some medication may interfere with the fast or vice versa. Be sure to know exactly what you need to do prior to starting the fast!

Check blood pressure levels

Even after you have gotten your doctor’s approval and have solid advice on how to continue with your medication during the fast, it is important to continue to monitor your blood pressure, even at home. The changes in electrolyte levels, lack of calories, or simply the way your organs react to the fast can have a significant impact on your blood pressure. If you feel unwell or see any sudden and unexpected changes in your blood pressure levels, check with your doctor immediately.

Water fasting

Although water fasting has seen increased popularity, it has many hidden dangers. This is, in no small part, also applies to water fasting with hypertension. As you will be neglecting many essential vitamins, minerals, nutrients and even base calories, this may have extreme adverse effects on your health and blood pressure.

This fasting method is better know as the 6/18 method or 8/16 method, meaning you will eat all your meals within 6 or 8 hours and fast for the remaining time each day. Even with high blood pressure, you can easily begin this method as your body will still receive vital nutrients and enough calories to allow your organs to regenerate and restore vital functions.
