On this page I save text I read on other pages while I am searching the World Wide Web. Text I want to remember and because I might need it later, I don’t store this on my private computer because I want to have access to it wherever I am. So I can show it to my doctor or whoever I want to tell this to.
Sometimes it’s not completely clear who wrote the original version of the text. I hope you will forgive me when I have used your text on this page. Just write me an email and I will save the text for my own use and hide it for others or I add the source of the text to it.
When potassium levels are low, which is usually between 2.5 to 3.5 mEq/L, the following symptoms can occur:
- pain in the muscles
- upset stomach
- mood swings
Potassium levels below 2.5 mEq/L affect many functions of the body including the muscles, digestion, kidneys, electrolyte balance, the liver and the heart.
Muscles: fatigue, pain in the joints, muscle weakness, muscle weakness after exercise, muscle stiffness, muscle aches, muscle cramps, muscle contractions, muscle spasms, muscle tenderness, pins and needles sensation, eyelid myotonia (cannot open eyelid after opening and then closing them).

I need to remember this and reed the article again in the future
“The most frequent is the hypokalemic form with a prevalence of 1:100,000.
It is transmitted with reduced penetrance in women (the male to female ratio is 3 or 4:1). The most common mutations are the Cav1.1 substitutions R528H and R1239H, which both lead to progressive myopathy.”
