  1. Sometimes I had the feeling of shaking inside my body. And DIZZINES, I'm always bloated and my digestion isn't good for almost four months now. The doctors said I have anxiety. After the symptoms appeared on me.
    It's strated by january after I took some corticosteriod meds for about three weeks 150mg was absorbed by my body everyday and I just stop it without tapering the meds. Now I don't know if it's still withdrawal side effect or anything..I always have problems in my nerves or maybe at my muscles. Cause I always had the feeling of shaking and sometimes my muscles twitching.
    I don't know if I had low potassium . Or something else or because I still have anxiety? but I always taking vitamin b complex. Though most of the time it makes me relieved but sometimes I just felt like the shaky is still there. And I feels so tired most of the time.

  2. I have one question.
    If diuretics cause more Na DOWNSTREAM and inhibitor Na apsorbation, how we have more Na for Na K pump?
    How that Na come to the principle cells if apsorbation is inhibition?

  3. Had my first brush with this a few days ago. Rapid heartbeat, which happened almost instantly. To say that it scared me would be an understatement. Initial EKG was abnormal as expected. Was given potassium pills and also potassium on an IV drip. Never much thought about the importance of potassium to that degree. I most certainly do now. I thought I was going to die, completely helpless feeling that I never want to experience again.

  4. I think there is something wrong. if potassium (which is positively charged) enters the cell it would become more positive in relation to the extracellular space and thus depolarizing it instead of hyperpolarizing it. As shown in the video, positive you subtract positive charges from the outside and give it to the inside the cell is more positive. indeed it is supposed to hyperpolarize but i don't believe it is possible unless positive charges are removed from the intracellular space making it relatively more negative. could you explain this please??

  5. I was diagnosed with hypokalemia year 2015. It was a scary experience since i couldn't move my legs.

  6. I suffered with hypokalemia for almost 1 year last 2008, and both of my legs was paralyzed. I can't walk and I can't feel anything if I touches the skin of my leg. Knowing that my potassium level is below normal, I started to change my diet. I ate a lot of bananas everyday. After 1 year, I am fully recovered. I became a missionary and every month I join mountain climbing activities. So for those who are suffering with this illness, don't loose hope.

  7. OH MY GOOOOOOOOOD
    THIS WAS SO SO SIMPLIFIEd THANK GOD THANK YOU GUYS OH MY GOD
    i was so scared of the upcoming exam and this fell like heaven
    i study in french mind you but the words are very similar and your explanation is amazing
    gonna watch hyper now

  8. I have been keeping my body alkaline every single day for months. Using Apple cider vinegar. I have been going through the worst muscle pain I have ever been through. I have had a leg amputation. Which sucked and the pain was violent. But these muscle aches almost tops it. Once I had a full week where I could barely walk and I ended up getting high af off of vicodin (pain killer). The pain was so unbearable I took more than what I should. I felt my body in panic and I thought I was going to die. But the pain was so bad that I just accepted it. I have pains regularly but that instance was the worst one. I have done exclusive research and found that Apple cider vinegar lowers potassium levels which has been causing my muscle pains. Now that I know this, starting tonight I am going to avoid apple cider vinegar, I just ate 3 Bananas so I should be good… theoretically

  9. Intravascular space means inside the blood vessels i.e between the rbc and wbc and platelets collectively known as extracellular space

  10. so basically I have a bad diet and I have to eat more potassium to regulate it by eating bananas n shit or it can be my kidneys n I can be fucked forever……cool

  11. excellent video, I'm a french boy with westphal disease and I like to understand how potassium works and what exactly is, this helps me to try to find ways to limit the crisis and the effects of my hypokalemia (around 1 big per week)
    So thank you for your video ^^
