What are the consequences of potassium deficiency in an 80 year old

Potassium deficiency in eighty-year-olds may cause a series of symptoms such as weakness, nausea, vomiting, fatigue, tachycardia, etc. In serious cases, it may even threaten the patient’s life.
Potassium deficiency will cause hypokalemia. Hypokalemia may cause a series of symptoms such as muscle weakness, loss of appetite, nausea, vomiting, tachycardia, and indifference, etc. Hypokalemia will also slow down gastrointestinal peristalsis, leading to intestinal paralysis, aggravate anorexia, and cause abdominal distension. In severe cases, coma, ventricular fibrillation, ventricular flutter, respiratory muscle paralysis and other symptoms may occur, and may even pose a serious threat to life.
Moreover, the prognosis of octogenarians may be worse than that of young people if they are not treated with potassium supplementation in time due to their old age.
Eighty-year-olds who develop hypokalemia are recommended to visit hospitals and be treated under the guidance of doctors.
