The MOST Serious Symptom of Potassium Deficiency

Potassium deficiency is incredibly common and can lead to serious problems. Find out about the most serious symptom of potassium deficiency and some of the causes of low potassium.

5:52 What causes potassium deficiency?

In this video, we’ll discuss the causes and symptoms of potassium deficiency. We need a lot of potassium—around 4700 mg per day! Most people eat a lot of junk food or processed foods high in salt and not enough potassium, which throws off the sodium-potassium ratio. Your body needs a 2:1 ratio of potassium to sodium.

Every cell in the body has a sodium-potassium pump that helps to generate electrical current around the cell, which powers the nervous and muscular systems.

Potassium is also important for the health of your blood vessels. Low potassium is one of the leading causes of high blood pressure; however, it isn’t often used in conventional medicine as a treatment. Over 90% of high blood pressure is essential hypertension, which means the cause is “unknown.”

Here are some signs of potassium deficiency:
•Muscular issues
•Abnormal heart rhythm
•Mental issues (delirium, hallucinations, psychosis, depression)
•Low back pain
•Increased pulse rate
•Increased risk of stroke

The most serious symptom of a potassium deficiency is sudden cardiac death. If you have low potassium, your risk for sudden cardiac death increases by 10x.

You could end up with low potassium if you’re not consuming enough potassium-rich foods like leafy greens, squash, nuts, shellfish, bone broth, avocado, pumpkin seeds, and sunflower seeds.

Other potassium deficiency causes include the following:
•Consuming refined sugar, refined starches, and refined grains
•Gut inflammation
•Alcohol consumption

    Great Video Dr Erric! Below are the Timestamped Summaries from ChatWithPDF:
    – 00:00🍌 Potassium is crucial and needed in large amounts, especially when compounded with high sodium intake.

    – 01:00⚡ Potassium is essential for generating electrical current to power the nervous and muscular systems.

    – 02:00💔 Symptoms of potassium deficiency include fatigue, muscle problems, abnormal heart rhythms, and mental issues.

    – 03:00💧 Potassium is needed to store glucose as glycogen, releasing water when depleted.

    – 04:00🩺 Potassium keeps arteries soft and elastic, crucial for blood pressure regulation.

    – 05:00❤ Sudden cardiac death and heart failure are the most serious risks of potassium deficiency.

    – 06:00🥦 Leafy greens, nuts, shellfish, and avocados are potassium-rich foods to prevent deficiency.

      Also the Omega3:Omega6 ratio is important as well.
      Lectins in low dose can be beneficial, there are some scientific papers that have found in them anti-cancer properties.

    After my work injury, I started to see doctors. They were shocked to see how low my blood potassium was when they did my blood analysis. My doctor prescribed potassium pills. I was also suffering from leg and hand cramping. A YT doctor said try taking magnesium. I started supplementing magnesium and I’ve never had a problem with potassium when the doctor has my blood work done.

  10. @intranger2848 on May 20, 2024 at 12:32 pm

    A tip for if you are looking for an easy way to increase potassium in your diet: Light salt! There are lots of brands on the market that use a blend of potassium chloride and sodium chloride. I use a brand that consists of 70% potassium chloride. Once dissolved, it tastes just like regular salt! (a bit weaker though, you will have to add more than usual)

    • @intranger2848 on May 20, 2024 at 12:35 pm

      And other than that, garden grown vegetables usually contain much more potassium than their mass farmed rivals.

    • @intranger2848 on May 20, 2024 at 12:36 pm

      Lastly, do remember that the 5g per day is based on an a multitude of diets. Certain diets (high carb) diets simply require more potassium to keep the blood potassium solid.

    • @intranger2848 on May 20, 2024 at 12:39 pm

      Besides, one needs less potassium if one decreases a previous over consumption of sodium, another pro of using a potassium salt mix!

    Sudden cardiac death killed my mother, who was recovering from colon cancer surgery in a rehab facility. I alerted the staff that potassium was a huge problem for her. She stood up for her physical rehab at the facility and died on the spot. Of, course, I didn’t know that until the hospital called me. The young er doc apologized profusely—said when she came in, her heart was like a stone and she was depleted of potassium. Maybe Dr. Berg should do a video on rehab profit centers.

One day i couldnt function or even think clearly so i called 9-1-1. The emt’s were sure i was having a drug overdose. And tbh that made sense. So i began to think i was being poisened. At the hospital i was told i had no drugs in me which i was relieved. But my potassium was extremely low. They gave me these huge potassium pills and my heart when back to normal within an hour. I was so happy. I felt like i just escaped death.

I was always low in potassium each time I had a heart attack I had to figure this out on my own that this might have been causing my heart attacks. I told them isn’t this strange I’m having low potassium each time I had a heart attack once I told them this they finally put me on a high dose potassium prescription. I feel like sometimes we have to become a doctor and learn about this stuff. I have learned so much from you! You are going to help so many people! Thank you Dr. Berg
