Causes of edema of legs and feet
(1) physiological reasons
Standing or walking for a long time: due to gravity and continuous tension of lower limb muscles, blood return slows down, which hinders venous blood return and causes edema.
Excessive salt intake: after eating a lot of salt, you will drink a lot of water, which will also cause changes in some hormone levels in the body, leading to tissue edema.
Senile edema: When people get old, the heart, liver and kidney function decrease, and the permeability of blood vessel wall increases, which makes it easier for water to run to the interstitial space through the blood vessel wall, causing edema.
(2) the cause of the disease
1. Heart: The heart's ability to pump blood is weakened, which easily leads to peripheral blood vessel congestion and edema.
2. Liver: The liver is the place where plasma proteins are synthesized. If the liver function is damaged, it is easy to reduce the protein in the plasma, leading to the retention of body fluids in the stroma and edema.
3. Kidney: The drainage capacity of the kidney is weakened, and the water and salt components in the body cannot be discharged in time, which is easy to edema.
4. Nutrition: When malnutrition occurs, the content of protein in the body decreases, and the content of protein in the plasma is low, which is prone to edema.
5. Endocrine: Some hormonal disorders that regulate water and electrolytes in the body are easy to cause abnormal water and salt metabolism and edema.
6. Blood vessels and lymphatic vessels: Varicose veins, venous thrombosis, lymphatic obstruction and other factors may also cause blood and tissue fluid stagnation and edema.
7. Thyroid gland: Due to the accumulation of mucopolysaccharide and other components in the tissue, edema is caused.
In addition to the above reasons, some drugs, leg and foot trauma, obesity, menstrual period and so on will lead to leg and foot swelling. For middle-aged and elderly friends, the common causes of leg and foot edema are excessive salt intake, senile edema, heart, liver and kidney diseases, vascular and lymphatic dysfunction and so on.
