Swelling of the limbs: causes, diagnosis, and treatment
About the Symptom
Swelling of the limbs is a condition characterized by the accumulation of excess fluid in the tissues, leading to an increase in the volume of fingers, hands, legs, or both limbs. This symptom can be triggered by various factors, including injuries, inflammatory processes, diseases of the heart, kidneys, or liver, as well as certain medications. Swelling can present as a temporary phenomenon that resolves on its own or as a sign of a serious medical condition that requires specialist attention.
It’s important to understand that swelling of the limbs may be accompanied by other symptoms, such as pain, changes in skin color, fever, restricted mobility, and general discomfort. Depending on the cause, the swelling can vary in severity and duration. For example, swelling caused by an allergic reaction may quickly resolve after taking antihistamines, whereas swelling caused by heart failure requires a more comprehensive approach to diagnosis and treatment. Therefore, when swelling of the limbs occurs, especially if accompanied by alarming symptoms, it is advisable to consult a doctor to determine the exact cause and receive the necessary assistance.
Diseases
Swelling of the extremities may indicate various diseases, many of which require medical intervention. These swellings can be the result of fluid retention in tissues, which in turn may signal more serious health problems. There are numerous pathologies where increasing swelling can be one of the prominent clinical manifestations, and ignoring them can lead to a deterioration in the patient’s condition.
The most common diseases accompanied by swelling of the extremities include cardiovascular pathologies, kidney diseases, as well as liver pathologies. Heart failure often leads to fluid accumulation, causing swelling, especially in the legs. Kidney problems can disrupt water-electrolyte balance, also provoking swelling. Liver diseases, such as cirrhosis, also play a significant role in the development of edema, as the liver is responsible for detoxifying and regulating protein in the blood.

Diagnosis
The diagnosis of limb swelling is an important step in determining the causes of this symptom. A comprehensive approach to assessing the patient’s condition includes both visual examination and the use of various laboratory and instrumental studies. The main task of the physician is to identify the source of the edema, which may be related to diseases of the heart, kidneys, blood vessels, or other pathologies. Correct diagnosis allows not only to identify the cause but also to determine the most effective treatment method.
During the diagnosis, a blood test may be required to determine levels of electrolytes and other substances, as well as an ultrasound examination to assess the condition of the blood vessels and identify possible thrombus formations. In some cases, specialized studies such as MRI or CT may be prescribed for a more detailed examination of the internal condition of the tissues. Therefore, the choice of diagnostic methods depends on the overall health status of the patient and accompanying symptoms.
List of diagnostic services:
- Complete blood count
- Biochemical blood analysis

Types of Limb Swelling
Limb swelling can take various forms depending on the underlying causes. The most common types of swelling include lymphatic, venous, and allergic swelling. Each of these types is determined by different physiological processes in the body and requires an individual approach to diagnosis and treatment.
Lymphatic swelling occurs due to disruptions in the lymphatic system, leading to the accumulation of lymph in the tissues. This type of swelling is more often observed in people with lymphatic vessel diseases or after surgical interventions. Venous swelling, in turn, is associated with venous insufficiency and impaired blood circulation. Allergic swelling, as the name suggests, arises from an allergic reaction and may be accompanied by itching and redness of the skin.
- Lymphatic swelling
- Venous swelling
- Allergic swelling
- Traumatic swelling
- Swelling caused by infections
Causes of Swelling in Limbs
Swelling in the limbs can be caused by a multitude of factors, both internal and external. One of the most common reasons is fluid retention in the body, which can occur for various reasons, including a sedentary lifestyle, high salt intake, or a lack of vitamins and minerals. The presence of chronic conditions, such as heart failure or kidney diseases, can also lead to fluid accumulation in the limbs.
Another significant cause of swelling in the limbs can be injuries or damages, such as sprains and fractures, which can cause local inflammation and swelling. It’s also worth noting that allergic reactions, infectious diseases, and certain medical conditions, such as lymphedema, can contribute to the development of swelling. It is important to consider all possible factors to approach diagnosis and treatment appropriately.

Common Related Pathologies
Swelling of the limbs can be a symptom of various diseases affecting both the cardiovascular and renal systems, as well as other organs. Edema often occurs as a result of fluid retention in the body, which may indicate the presence of serious disorders. For example, heart failure is one of the most common causes of edema. In this condition, the heart cannot effectively pump blood, leading to fluid accumulation in the lower limbs.
Another frequent cause of limb swelling is kidney problems, such as nephrotic syndrome, which involves protein loss, subsequently causing fluid retention. It is also worth mentioning liver diseases, such as cirrhosis, which can disrupt normal metabolism and again lead to fluid accumulation. An important aspect of diagnosis is identifying and treating underlying conditions to prevent further deterioration of the patient’s condition.
