What causes ankle swelling?

People will always encounter some accidental injuries in life and work. Not only some high-risk jobs will cause physical injuries, but some children and the elderly will also suffer some accidental physical injuries in life. Some young people who exercise regularly will experience this situation. Redness and swelling of the ankle is a common condition, and most people don’t know why it occurs. So, what causes ankle swelling?

First, what causes ankle swelling? Ankle swelling is a type of lower limb swelling. Sitting for a long time, neglecting exercise, or some bad daily behavior habits may cause ankle swelling. What is more important is that ankle swelling is often one of the symptoms of some major diseases, such as heart disease, nephritis, liver cirrhosis, etc. Therefore, once you find yourself with long-term ankle swelling, you should seek medical treatment in time to determine the cause. Malnutrition edema is mainly caused by hypoproteinemia or vitamin deficiency due to long-term nutritional deficiency caused by chronic wasting diseases, protein-losing gastrointestinal diseases, severe burns, etc. The characteristic is that edema is often preceded by emaciation and weight loss. Edema often starts in the feet.

Second, renal edema is mainly seen in various types of nephritis and kidney disease. The pathogenesis is mainly caused by multiple factors that cause reduced renal excretion of water and sodium, leading to sodium and water retention, increased extracellular fluid, increased capillary hydrostatic pressure, and causing edema. The characteristic of edema is that in the early stage of the disease, there is eyelid and facial edema when getting up in the morning, which later develops into systemic edema. Urine changes, high blood pressure, and renal impairment are common.

Myxedema is mostly caused by excessive protein content in the tissue fluid. It is more common in hypothyroidism and is more obvious in the face and lower limbs. The above are the specific reasons for ankle swelling. I hope that patients will pay more attention in their daily lives and take active preventive measures to avoid ankle swelling from developing into serious diseases and causing great harm.

What causes ankle swelling? Posture factors: walking or standing for a long time, improper sitting posture, legs hanging down for too long, and long-term sitting can lead to poor blood circulation in the lower limbs, thereby reducing the auxiliary effect of muscle movement on venous blood return and causing edema. Ill-fitting shoes can also cause edema, which will subside after rest. Physical factors: Edema worsens after fatigue and long-term standing, and is relieved after bed rest. When standing upright, renin activity in the blood increases, causing an increase in aldosterone, so edema may appear in the sagging parts of the body such as the ankles, and in severe cases, edema may also appear in other parts of the body. After resting at night, the edema can be absorbed and disappear.
