Leg edema in the elderly is partly related to heart, kidney, liver and endocrine diseases, and a considerable part is idiopathic senile edema. This edema is mostly caused by the loose subcutaneous tissue space of the elderly and the easy infiltration of water into the tissue space. More detailed reasons are as follows:
1, long-term malnutrition and anemia will lead to hypoproteinemia, and edema of lower limbs and whole body may also occur.
2. Some elderly people have a heavy taste and like to eat hot and sour recipes, which leads to excessive sodium intake and edema.
3, internal organs disease, at this time, foot swelling is only a symptom of the disease. Different diseases cause edema in different ways.
(1), when chronic right heart failure is caused by heart disease, edema begins at the ankles of both lower limbs and gradually develops to the whole body.
(2), cirrhosis, but also from the initial edema of both lower limbs, to later ascites, and finally systemic edema.
(3) Patients with kidney disease will also have edema of lower limbs, but it usually starts with edema of double eyelids or face, and then develops to the whole body.
4. Slow blood circulation. Some people always like to curl up their feet or get hit by something, which may lead to poor blood circulation in their feet.
5. For example, male elderly people suffer from prostatic hypertrophy or prostatitis, and some elderly people suffer from bladder tumors. Urinary retention leads to renal insufficiency, which eventually leads to edema of lower limbs.
6, idiopathic foot swelling, more common in elderly women, multiple feet appear at the same time, to a lesser extent, often appear when standing for a long time or tired, if you lie down or rest, you can gradually disappear.
7. The climate will also cause swollen feet to some extent. In hot weather, most of the peripheral blood vessels of the human body are dilated, which makes the capillaries congested, so the skin, subcutaneous tissue and soft tissue are slightly swollen, which is the same as expansion with heat and contraction with cold.
What is the cause of edema of the elderly feet? Reasonable diet control can effectively prevent foot edema, which may be caused by unreasonable diet. Control salt intake and exercise properly. Slow blood circulation can also cause edema of lower limbs, and malnutrition can also cause edema of lower limbs.
