The statement of “10 manifestations of potassium deficiency” lacks scientific basis. Generally speaking, potassium deficiency in the body will show symptoms such as muscle weakness, arrhythmia, gastrointestinal discomfort, etc., and the performance of different patients is not exactly the same. 1. Neuromuscular symptoms: weakness, muscle weakness, slow movement, muscle twitching and spasm, drowsiness, coma, dysphagia, dyspnea and other symptoms. 2. Cardiac symptoms: manifested as panic, palpitation, arrhythmia, etc. In severe cases, ventricular fibrillation and heart failure may occur. 3. Digestive system symptoms: may manifest as nausea and vomiting, anorexia, abdominal distension, constipation, defecation difficulties, and so on. Potassium plays an important role in the normal functioning of the body. It is recommended to consult a doctor in time after the occurrence of suspicious symptoms, and to find out the cause of low potassium and then treat accordingly.
