00:00Imagine this, someone feels a little more tired than usual, their muscles feel weak,
00:05maybe they even notice their heart beating a little irregularly.
00:09It doesn't seem like an emergency until suddenly it is. A simple abnormality in a blood test,
00:18something as small as a low potassium level, can quietly progress into a life-threatening condition.
00:26A low level of potassium in your blood can be dangerous and in some cases it needs to be treated
00:35immediately.
00:37Here's why. Potassium is the most abundant positively charged ion found inside your cells.
00:45It is crucial for maintaining multiple vital functions in the body.
00:50About 98% of the potassium in your body is found inside your cells, with only a small fraction circulating
00:59in the blood.
01:00In the cell, potassium helps maintain the electrical gradient across the cell membrane.
01:07This gradient helps the nerve cells transmit signals around the body.
01:12Low potassium can disrupt the electrical balance across nerve cells, making it harder for them to send signals properly.
01:20In the same way, potassium is important for muscle contraction.
01:26If the body lacks potassium, muscle contraction can be impaired, leading to weakness.
01:32For these reasons, people with severe potassium deficiency can experience weakness and paralysis.
01:41If the muscles that control the chest wall become paralyzed, breathing can stop.
01:48This is rare, but it is potentially fatal.
01:52Potassium is also crucial for controlling the heartbeat.
01:56Low levels of potassium in the heart muscle cells can disrupt the electrical system in the heart, causing the heart
02:04to beat irregularly.
02:06Very low levels can cause the heart to speed up into a dangerous rhythm called ventricular tachycardia.
02:13And this is potentially fatal.
02:17Potassium also interacts with the body's acid-base balance.
02:22When potassium levels are low, it can alter how the kidneys handle acids and bases, sometimes leading to disturbances in
02:32the acid-base balance of the blood.
02:34But what are the causes of low potassium?
02:37There are many causes of low potassium, including medications such as water pills that excrete potassium in the urine.
02:45Certain asthma medications like inhaled beta agonists and even insulin injections can cause low potassium levels.
02:54When people vomit or have severe diarrhea, the body loses potassium from the GI tract.
03:01People who are born with some hereditary diseases can lose potassium through their kidneys.
03:08They can sometimes develop periodic muscle weakness because of this.
03:13If the diet does not contain adequate amounts of potassium, you can develop low potassium levels.
03:20But this is a real cause of low potassium.
03:24Magnesium is essential for maintaining potassium levels.
03:29When magnesium is low, the kidneys lose potassium more easily.
03:33And potassium levels may not improve until magnesium is corrected.
03:38A low potassium level is not something to be taken lightly.
03:44Because of the critical role potassium plays in the body, low levels, especially when severe, may require prompt evaluation and
03:54correction.
