Causes and treatment of leg swelling: expert advice
About the Symptom
Swelling of the legs is a common and often unpleasant condition that manifests as the accumulation of excess fluid in the tissues of the lower extremities. This can lead to significant discomfort and even limitations in mobility. Swelling can be either temporary or chronic, depending on the underlying causes. Often, this symptom may indicate more serious medical issues such as heart failure, kidney diseases, or venous disorders. Therefore, it is important to pay attention to its emergence and consult a specialist for diagnosis of the cause.
The process of swelling is associated with disorders in blood and lymph microcirculation. When this system does not function properly, fluids begin to accumulate in the interstitial space, leading to swelling. The symptom can manifest in different ways: from mild puffiness to severe swelling, which may be accompanied by pain, redness of the skin, and even fever in the swollen area. Most often, leg swelling worsens after prolonged standing or sitting, as well as in hot weather when blood vessels dilate. Pay attention to such changes in your body, as timely consultation with a doctor can help prevent the development of serious diseases.
Diseases
Swelling of the legs can be a sign of various medical conditions, each requiring careful diagnosis and treatment. The most common causes of swelling include cardiovascular diseases, such as heart failure, when the heart cannot effectively pump blood, leading to fluid accumulation in the limbs. Swelling can also be a consequence of kidney diseases, which are responsible for filtering and eliminating excess fluid from the body.
Moreover, swelling of the legs may indicate issues with the veins, such as varicose veins or thrombophlebitis. These conditions lead to impaired blood circulation and fluid retention. Internal inflammatory processes, such as infections or injuries, can also cause swelling. Understanding the nature of the swelling and its causes is very important for prescribing the correct treatment and preventing serious complications.

Types of Leg Swelling
Leg swelling can manifest in various forms, and understanding these types helps in diagnosing the causes and choosing the appropriate treatment. One of the most common types is venous swelling, which occurs due to poor blood and fluid drainage in the veins of the lower extremities. This type of edema is often accompanied by discomfort and fatigue in the legs, especially after prolonged standing or sitting.
Another common type of swelling is lymphatic swelling, which is caused by impaired lymphatic drainage. In this case, the tissues are affected by swelling, which is often persistent. It is also important to highlight swelling caused by allergic reactions or inflammatory processes that can occur as a result of injuries or infections. It is important to know that swelling can be a symptom of more serious diseases, so it should not be ignored.

- Lymphatic swelling
- Allergic swelling
- Swelling caused by injuries
- Swelling in inflammatory processes
Reasons for Leg Swelling
Leg swelling is a symptom that can occur for various reasons. Most often, it is caused by the accumulation of excess fluid in the tissues, leading to their enlargement and swelling. The main factors contributing to swelling can be both physiological and pathological. Physiological causes include prolonged standing or sitting, which can lead to impaired venous outflow and blood accumulation in the extremities. Swelling can also occur due to increased environmental temperature, which causes the dilation of blood vessels and increased permeability of capillary walls.
Pathological causes of leg swelling are associated with various diseases, such as cardiovascular disorders, kidney diseases, and liver diseases. Heart failure can cause fluid retention in the body, which directly affects the condition of the legs. Kidney pathologies, including kidney failure, lead to decreased fluid excretion from the body, which also results in edema. Liver diseases, such as cirrhosis, can disrupt circulation and lead to fluid accumulation in the lower extremities.
- Physiological causes: prolonged standing, hot weather.
- Cardiovascular diseases: heart failure.
- Kidney pathologies: kidney failure.
- Liver diseases: cirrhosis.
- Varicose veins.
- Allergic reactions.
Common Related Pathologies
Swelling of the legs can be a symptom of various diseases that can significantly affect a person’s overall health. One such disease is heart failure, where the heart is unable to pump blood effectively, leading to fluid retention in the body and, consequently, to swelling. It is also worth noting that kidney diseases, such as chronic kidney failure, can cause sodium retention and an increase in fluid volume in the body, which also manifests as swelling.
Other common pathologies include liver diseases, such as cirrhosis, where the synthesis of proteins responsible for maintaining oncotic pressure in the vascular system is disrupted, which can also lead to swelling. Disorders in the function of veins—such as venous insufficiency or thrombophlebitis—can also cause localized swelling associated with increased pressure in the veins and fluid retention in the tissues.
