There are various electrical ions in the body, such as calcium ions, potassium ions, and sodium ions. If the electrical ions in the body are not in the normal range, it is an electrolyte disorder. Whether mild electrolyte disorders can recover on their own depends on the patient’s condition. The main causes of electrolyte disorders are excessive loss and inadequate intake, such as severe vomiting and low intake of food. Electrolyte disorders can lead to abnormal transmission in the nervous system and abnormal metabolism in the endocrine system, which can cause different degrees of damage to the body. If the patient is suffering from mild electrolyte disorders due to diarrhea, and the diet is not affected, then the mild electrolyte disorders can usually return to normal by themselves after dietary adjustments. If the patient can not eat normally, nausea, vomiting, diarrhea and other symptoms are serious, then electrolyte disorders can not be recovered by themselves, need to go to the hospital endocrine or emergency department. In addition, if the patient has endocrine system diseases, should actively go to the endocrinology department for treatment. It is recommended that patients should pay attention to dietary hygiene in daily life, do not overeat, eat less cold food, balanced nutrition, and avoid excessive dieting.
