PEMF Side Effects

You’re considering Pulsed Electromagnetic Field therapy, but what about the side effects? Like any treatment, it’s important to know what you’re potentially up against.

This article dives into the sometimes overlooked aspects of PEMF therapy, from temporary pain increases to changes in blood pressure.

We’ll also discuss special considerations for groups like pregnant women.

So let’s arm you with the knowledge you need to confidently navigate your PEMF journey.


When you’re undergoing PEMF therapy, one side effect you might experience is oxidative stress, an imbalance that occurs when your body can’t effectively detoxify the free radicals produced by the increased blood flow. This imbalance is a result of the therapy’s effect of boosting your circulation. While this increased blood flow has many benefits, it also accelerates the production of free radicals – unstable molecules that can damage cells in your body.

Oxidative stress happens when these free radicals outnumber the antioxidants in your body. Antioxidants are molecules that can neutralize free radicals and mitigate their harmful effects. When there’s an excessive amount of free radicals, your body’s capacity to counteract their effects is overwhelmed. The result is oxidative stress, which has been linked to various health conditions including heart disease, cancer, arthritis, stroke, respiratory diseases, immune deficiency, and Parkinson’s disease.

Before you start to worry, understand that there are measures you can take to counteract this effect. One way is by consuming antioxidant-rich foods. These include apples, spinach, kale, strawberries, and other fruits and vegetables. These foods can help to increase your body’s antioxidant capacity and fight oxidative stress. Moreover, taking antioxidant supplements before and during therapy can further boost your body’s defenses against free radicals.

Keep in mind that while PEMF therapy can lead to increased oxidative stress, this is generally a temporary effect. With proper nutritional support and under the guidance of a healthcare professional, you can safely undergo PEMF therapy and enjoy its many benefits. It’s essential to monitor your body’s reaction to the therapy and adjust your antioxidant intake accordingly.


A noteworthy side effect you might experience with PEMF therapy is a temporary increase in pain. This surge primarily occurs due to enhanced circulation to nerves and increased traffic to nerve cells. While this effect might seem discouraging, it’s crucial to understand that it’s a temporary phase and part of the healing process.

For patients in severe pain, starting PEMF therapy at the lowest intensity possible is a recommended strategy. This approach minimizes the initial discomfort, allowing your body to adjust to the therapy gradually. It’s essential to listen to your body and adjust the therapy intensity accordingly so you don’t exacerbate your pain.

Another side effect that accompanies this temporary increase in pain is nutritional deficiency. This deficiency arises because your body cells use more nutrients during therapy, potentially leaving you deficient in vital nutrients. This is particularly important if you’re already suffering from a nutritional imbalance.

To counteract this, it’s advised to seek professional guidance from a nutritionist. They can provide you with a tailored dietary plan rich in essential nutrients to support your body during therapy. Also, consider using specially designed PEMF devices supervised by trained specialists to mitigate these side effects.


After addressing the temporary increase in pain, another side effect you might encounter during your PEMF therapy journey is a decrease in blood pressure. This reduction in pressure can sometimes lead to a lower heart rate.

While this side effect is generally harmless for most, it can pose significant risks for certain individuals.

Elderly patients or those with underlying cardiovascular defects can experience severe complications from this drop in blood pressure. Their bodies mightn’t be as resilient or adaptable to these changes, and the decreased blood pressure can exacerbate their existing conditions.

Similarly, for patients who’ve been on bed rest for extended periods, this effect can be particularly problematic. Their bodies may have adapted to a certain level of blood pressure, and a sudden decrease can cause a shock to their system.

Common symptoms associated with this decrease in blood pressure include dizziness and fainting, particularly after a change in position. This can happen because your body hasn’t had time to adjust to the lower blood pressure, leading to a temporary lack of blood flow to your brain.

To navigate this potential side effect, it’s crucial to monitor your blood pressure regularly throughout your PEMF therapy. If you notice a significant decrease, it’s advisable to consult your healthcare provider. They can provide you with the necessary guidance and adjust your treatment plan if necessary.


Another side effect you may encounter with PEMF therapy is a significant drop in your blood sugar levels. This decrease in glucose concentration can be alarming, particularly for individuals who already struggle with regulating their blood sugar levels. The mechanism behind this effect isn’t entirely clear, but it’s believed to be associated with the therapy’s action on cell membranes, enhancing glucose uptake and utilization in the tissues.

As the therapy increases the movement of ions across the cell membranes, glucose transportation could also be intensified, resulting in lower blood sugar levels. If you’re diabetic or hypoglycemic, this could potentially complicate your condition. For instance, a sudden decrease in glucose levels can trigger symptoms like confusion, dizziness, or even loss of consciousness in severe cases.

Moreover, PEMF therapy has been found to promote coagulation or blood clotting. This implies that it may not be suitable if you’re on anticoagulant medication such as aspirin. The therapy’s influence on blood clotting speed could counteract the effect of these medications, increasing the risk of clot formation and subsequent complications like stroke or heart attack.

It’s also worth noting that the blood sugar reduction isn’t universally experienced by all individuals undergoing PEMF therapy. Factors such as your metabolism, overall health, and the intensity and frequency of your PEMF sessions might influence your likelihood of experiencing this side effect.

To navigate these potential risks, it’s crucial to monitor your blood sugar levels closely while undergoing PEMF therapy. In case you notice significant changes, consult your healthcare provider immediately to discuss possible adjustments to your treatment plan.


Beyond these impacts on your blood sugar levels, there’s a range of other side effects you might experience during your PEMF therapy journey. These side effects can vary from person to person, largely dependent on your individual health conditions and sensitivity to magnetic and electric fields.

  • Sensory Reactions
  • You may experience sensations of warmth or cold, or even a tingling feeling throughout your body.
  • Sleep disturbances and feelings of fatigue or loss of energy can also occur.
  • Dizziness and increased urination are another couple of side effects some patients report.
  • It’s important to note that these sensory reactions can be more intense for those with pre-existing conditions like chronic fatigue syndrome or fibromyalgia.
  • Dermatological Concerns
  • If you have a dermatological condition, you should avoid PEMF therapy as it may exacerbate your symptoms.
  • Therapeutic Interactions
  • PEMF therapy can interact with other medications or treatments you’re undergoing.
  • For instance, if you’re undergoing chemotherapy, it’s contraindicated to start PEMF therapy as it promotes cell growth and repair, possibly enhancing the growth of cancer cells.
  • However, research in this area is ongoing, with some studies suggesting that PEMF therapy could actually enhance the effects of chemotherapy.
  • Pregnancy Precautions
  • If you’re pregnant, it’s advised to avoid PEMF therapy as it’s considered a teratogen, potentially causing harm to your unborn baby.

As with any form of therapy, it’s crucial to discuss these potential side effects with your healthcare provider before starting PEMF therapy. This way, you’ll be able to make an informed decision about your health and wellbeing.


In conclusion, while PEMF therapy can offer significant health benefits, it’s crucial to be aware of potential side effects.

You may experience oxidative stress, temporary pain increase, lower blood pressure, and a drop in blood sugar levels. Additionally, there may be other effects specific to your condition or health status.

Understanding these risks empowers you to make informed decisions about your health, balancing the benefits and potential drawbacks of PEMF therapy.
