1. To prevent old and rotten legs, first of all, we should seek medical advice at an early stage, make a clear diagnosis and treatment, maintain and improve the smooth venous return, and remove tissue congestion. If you have a history of venous ulcers. Deep venous thrombophlebitis and venous valve insufficiency. Should be actively treated. Prevent the disease from developing and worsening.

2. Avoid standing for a long time, which can prevent old rotten legs from sitting for a long time. When the human body stands or sits still for a long time. Blood is affected by gravity. The pressure on the venous valve of the lower extremity is greater. The calf muscles are in a relatively relaxed state. Poor blood emptying in venous cavity. The valve continues to bear more pressure. When the pressure is greater than the pressure borne by the valve. Abnormal blood reflux in veins is becoming more and more serious. Finally, local venous congestion is aggravated. So avoid standing for a long time, sitting for a long time, and have a proper rest. Activities.

3. Prevent the intra-abdominal pressure from rising for a long time. The increase of intra-abdominal pressure will affect the venous blood return of lower limbs. Causes the venous pressure of lower limbs to increase. It increases the damage of venous valve or aggravates the burden of venous valve. Therefore, active treatment of diseases that lead to increased intra-abdominal pressure can prevent old rotten legs.

4. Raise the affected limb and promote venous blood return of lower limbs. Rest properly and raise the affected limb. So as to promote the blood return of the affected limb, reduce the swelling of the affected limb and prevent leg ulcers. The patient lifted the affected limb. 3-5 times a day, each time for half an hour is appropriate. Encourage walking. Improving blood circulation can prevent legs from getting old and rotten.

5. Prevent trauma. Because the vein is tortuous, the vein wall is very thin, which is easy to be broken, broken and bleeding. Therefore, attention should be paid to protecting the affected limb to avoid traumatic frostbite or insect bite, which can prevent old and rotten legs.
