Elderly people walk around with swollen legs due to cardiac insufficiency, renal insufficiency, hypoproteinemia, lower extremity venous valve insufficiency.
1. Cardiac insufficiency: chronic heart failure patients with a decrease in the amount of return blood, resulting in increased venous pressure, tissue interstitial deposition, resulting in swelling of the legs.
2. Renal insufficiency: due to the decrease of glomerular filtration rate and metabolite retention, patients with renal insufficiency may show symptoms such as decreased urine output, edema and hypertension.
3. Hypoproteinemia: seen in various systemic diseases, due to the decrease of plasma concentration, it can cause edema, infection, ascites, emaciation and other symptoms.
4. Lower extremity venous valve insufficiency: with the increase of age, or due to long-term heavy physical labor, the function of lower extremity venous valves have problems, standing or walking for a long time will appear leg swelling phenomenon.
There are many reasons why old people’s legs are swollen when they walk, and it is necessary to make a comprehensive diagnosis by combining relevant laboratory tests and imaging tests, as well as the patient’s past medical history, and then targeted treatment.
