High Potassium levels, or hyperkalemia, may present various symptoms. Early signs can include muscle weakness, fatigue, numbness, or tingling sensations. As Potassium levels increase, more severe symptoms can occur, such as palpitations, irregular heart rhythms, chest pain, difficulty breathing, and paralysis. However, it's important to note that symptoms can vary from person to person, and some individuals may not experience noticeable symptoms until Potassium levels become very high. If you suspect high Potassium levels, it is crucial to seek medical attention for proper evaluation and diagnosis.
