High potassium, also known as hyperkalemia, occurs when the levels of potassium in your bloodstream are severely elevated. Although potassium is essential to the proper functioning of the human body, too much of it can be harmful and even life-threatening.
However, the symptoms of dangerously high potassium can be initially challenging to detect, especially in the early stages.
The early signs and symptoms of high potassium levels typically include muscle weakness or fatigue, nausea, vomiting, and an irregular heartbeat. When the potassium levels rise above 6.0 mmol/L, the patient may experience additional symptoms such as chest pain, difficulty breathing, and confusion.
Other symptoms that can be observed in severe cases include paralysis, muscle breakdown (rhabdomyolysis), and even cardiac arrest.
In some individuals, high potassium levels may also cause gastrointestinal disturbances such as abdominal discomfort, frequent urination, and intense thirst. However, the severity of these symptoms will vary depending on the individual’s overall health, age, and the underlying cause of hyperkalemia.
It is also important to note that high potassium levels are usually indicative of underlying medical conditions such as kidney failure, Addison’s disease, and Type 1 diabetes. These conditions can impair the kidneys’ ability to regulate potassium levels in the body, leading to a build-up of potassium in the bloodstream.
High potassium levels can lead to a variety of symptoms, from mild to life-threatening. Anyone experiencing symptoms of hyperkalemia should seek medical attention immediately, as early intervention can prevent long-term complications or even death.
Regular blood tests can help in early detection and management of high potassium levels, especially in individuals with a history of kidney disease or other underlying medical conditions.
