How to prevent leg swelling and pain after sedentary?

The causes of edema of lower limbs are pathological and functional.

Foot swelling is caused by many factors, but most of them are caused by functional factors. The specific reasons may be as follows:

1, body position coefficient:

Walking or standing for a long time, improper sitting posture, long legs drooping and sedentary will all lead to poor blood circulation of lower limbs, so reducing the assistance of muscle exercise to venous blood return will cause edema. Improper shoes can also cause edema. This edema will subside after rest. When the weather is hot, edema will get worse.

2. Climate factors:

When the weather is hot, most of the peripheral blood vessels of the human body expand, which makes the capillaries congested, so the skin, subcutaneous tissue and soft tissue swell slightly, which is the reason why heat expands and cold contracts.

Three physical factors:

Female edema is also related to promoting the transfer of intravascular fluid to tissue space. For women of childbearing age, edema can be seen in hands, breasts, buttocks, abdomen, lower limbs and other parts. Patients have the characteristics of poor posture adaptability, that is, fatigue and edema are aggravated after standing for a long time, and relieved after bed rest. This edema is related to the increase of renin activity in blood when standing upright, which leads to the increase of aldosterone. Therefore, edema can occur in drooping parts of the body, such as ankles, and edema can also occur in other parts when it is heavy. After rest at night, edema can be absorbed and disappeared.

Overweight or obese patients, especially women, are prone to functional edema of lower limbs, and the subcutaneous tissue of obese people increases, which can weaken the supporting effect on superficial veins, make them easy to expand and reduce extravascular pressure; After losing weight and increasing exercise, edema can be improved or disappeared.
