If it is a short-term sodium overdose, that is, salt eating too much, but the amount is not very large, the body in this case will compensate to increase the excretion of sodium ions to maintain the balance of electrolytes in the body, the body will not have too much impact in the short term. However, if it is too much sodium intake for a long time, it may cause other problems, such as hypertension, gastric mucosal damage, kidney damage, skin damage, etc. 1, hypertension: high sodium diet is most likely to trigger hypertension, which will lead to water and sodium retention in the body, and also activate the sympathetic nerve and the renin-angiotensin-aldosterone system, all of which will raise the patient’s blood pressure, which will lead to cardiovascular disease; 2, gastric mucosal damage. Excessive sodium intake may directly stimulate the gastric mucosa, resulting in acute and chronic gastritis, and long-term consumption of excessive sodium may even induce gastric cancer; 3, kidney damage: if excessive sodium intake will also cause a great burden on the kidneys, which may cause glomerular arteriosclerosis in the long run, resulting in reduced glomerular filtration rate, so that water and sodium can not be discharged normally, thus causing patients to develop Systemic edema and creatinine elevation, may cause chronic renal insufficiency; 4, skin damage: if too much sodium intake, may lead to dehydration of skin cells, causing accelerated aging of skin cells, inducing skin itching, rashes, etc.; 5, other: excessive salt intake can also lead to hypernatremia, osteoporosis and other conditions, patients need to be under the guidance of professional doctors for drug treatment. In daily life, patients need to control the intake of sodium, normal people should not exceed 6g of salt intake per day to avoid triggering the above-mentioned adverse conditions.
