What is the reason for swelling on one foot

It is very common for people to suffer physical injuries due to unexpected situations in their daily life and work, especially some minor physical injuries such as swollen feet. Many people do not know the cause of this situation when they encounter it, and do not know what methods should be used to alleviate it. So, what causes a swollen foot?

First, what is the reason for swelling on one foot? Some people have inexplicable swelling of the feet. There are many reasons for swollen feet. One is pathological reason, and the other is functional reason. If your feet swell when it's hot, it may be caused by a combination of factors, but most of them are functional factors. The specific cause requires a specific analysis of inferior vena cava foot swelling, which is mainly caused by poor blood flow from the inferior vena cava, and generally manifests as unilateral foot swelling. One possibility is due to eating less and lack of high-quality protein. If you have been anorexic recently and your feet are swollen, this may be the reason. The climate can also cause swollen feet to a certain extent. When it is hot, most of the blood vessels around the human body are in a state of expansion, causing the capillaries to become congested, so the skin, subcutaneous tissue and soft tissues all show slight swelling, which is the same principle as thermal expansion and contraction.

Second, kidney disease can cause swollen feet. For example, nephritis can cause swollen feet. Some swollen feet may be a sign of disease and should be taken seriously. There is also the saying that high blood pressure causes swollen feet. There are many other theories, such as other theories related to physical constitution. Without sufficient scientific verification, they may not be right or wrong, so I will not delve into them.

What is the reason for a swollen foot? Idiopathic foot swelling is common in elderly women, often occurring when standing for a long time or when tired, and disappears if lying flat or resting. Functional foot swelling is more common in elderly women, often occurring intermittently, and generally lasting for several years. Some patients' foot swelling is related to the season, but not to body position. The cause is still unknown. Nutritional foot swelling is caused by the lack of nutrition in the body due to the elderly eating less, decreased digestive function or suffering from chronic diseases. Patients are often accompanied by anemia, and are prone to infectious diseases due to decreased immune function. Cardiogenic foot swelling is caused by decreased heart function, especially in patients with right heart failure. At this time, pathological changes such as organic murmurs and heart enlargement can be found in the heart examination. Inferior vena cava foot swelling is caused by poor reflux of the inferior vena cava, and one foot swells first. This is due to thrombosis in the inferior vena cava and compression of the inferior vena cava by tumors in the pelvic cavity. Once the elderly have swollen feet, they must go to the hospital for a comprehensive examination to find out the cause and treat it in time.
