Edema is a condition characterized by swelling and puffiness in tissues due to excessive fluid accumulation in the body. Typically observed in areas such as the legs, ankles, hands, and face, edema can sometimes occur in different parts of the body as well. Factors causing edema include heart failure, kidney diseases, liver issues, hormonal imbalances, and lymphatic system disorders. Edema detected in its early stages can be managed effectively with appropriate strategies.
What is Edema?
Edema occurs due to increased fluid passage from vessels into tissue spaces or inadequate reabsorption of this fluid. Often, increased capillary permeability, elevated intravascular pressure, or impaired lymphatic drainage facilitate this condition.
Edema can become noticeable in areas like the legs, ankles, hands, face, and abdomen. A feeling of tension in the skin, bloating, weight gain, and indentations upon touch might also be experienced. These processes develop based on the individual's current health status, lifestyle habits, and environmental factors.
What are the Symptoms of Edema in the Body?
Edema in the body generally presents with symptoms such as a sense of heaviness, skin tightness, swelling, and firmness. It is crucial to consult a doctor if edema, especially in areas like the hands, ankles, legs, and face, is observed. Medical help should be sought if there are complaints such as sudden weight gain, ineffectiveness of diuretic medications, and shortness of breath.
Clinically, edema may present with the following findings:
-
Marked swelling in the lower extremities
-
Tightness in the skin
-
Indentation formation when pressed with a finger (pitting edema)
-
Morning periorbital edema
-
Tightness in footwear or rings
-
Unexplained increase in daily weight tracking
-
Fatigue and overall body weakness
Why Does the Body Retain Edema?
The causes contributing to edema formation in the body can be evaluated under two main categories: physiological and pathological. The clinical approach followed may vary depending on the source of the edema.
Physiological Causes
Physiological edema usually develops based on lifestyle and environmental factors. Such edemas are short-term and do not stem from an underlying illness. However, prolonged persistence may require medical evaluation.
Excessive Salt Consumption
Foods high in salt can lead to sodium accumulation in the body, causing an increase in extracellular fluid. This effect of sodium causes water retention in tissues, leading to edema development.
Inadequate Water Consumption
If sufficient water is not consumed, the body tends to retain water in tissues to compensate for fluid deficiency. This situation can activate the kidney's water reabsorption mechanisms, contributing to edema.
Inactivity and Prolonged Postural Disorders
Remaining in the same posture for a long time reduces venous return in the lower extremities. Slowed circulation causes fluid passage into tissues under the influence of gravity, resulting in edema in the legs.
Hormonal Changes
Variations in estrogen and progesterone levels during periods like the premenstrual cycle, pregnancy, and menopause affect the body's fluid balance. This situation can lead to transient edema development, especially in women.
High Temperature and Humid Weather
In hot weather, vessels dilate (vasodilation), which facilitates the passage of fluid from vessels into surrounding tissues. Increased edema in the hands and feet can be commonly observed in summer.
Pathological Causes
Pathological edema develops due to an underlying organ dysfunction and can be chronic. Determining the cause of such edemas is crucial for accurate diagnosis and treatment.
Heart Failure
Decreased pumping capacity of the heart causes inadequate blood supply to tissues and venous blood pooling. This situation can manifest as symmetrical edema, especially in the legs and ankles.
Kidney Diseases
Impaired kidney filtration affects fluid and electrolyte balance. Conditions like nephrotic syndrome cause protein loss, reducing intravascular oncotic pressure, which can trigger edema development. Edema prominently in the eyelids and face in the mornings can be kidney-related.
Liver Failure
Reduced liver capacity for protein synthesis makes it difficult to retain blood within vessels. Consequently, fluid accumulation in the abdomen and edema in the ankles are frequently observed.
Thyroid Gland Insufficiency (Hypothyroidism)
Decreased thyroid hormones lead to mucopolysaccharide accumulation between tissues, resulting in a non-pitting edema known for its hardness and lack of compression upon pressing.
Lymphatic Drainage Disorders (Lymphedema)
Insufficient congenital development of lymph vessels or blockage post-surgery, trauma, or infection causes chronic and typically unilateral edema known as lymphedema.
How to Eliminate Edema from the Body?
Reducing salt intake, drinking plenty of water, regular exercise, and resting with the feet elevated can help eliminate edema from the body. If edema is recurrent or severe, it is essential to consult a healthcare professional.
Effective methods to eliminate edema include:
-
Reducing salt consumption
-
Wearing compression stockings under medical supervision
-
Walking
-
Cycling
-
Massaging the edematous area
-
Avoiding tight clothing
-
Eating a healthy diet
-
Taking vitamin B6 supplements
Foods that help reduce edema:
-
Parsley
-
Cucumber
-
Watermelon, pineapple
-
Lemon water
The use of such foods should consider individual health status. People with kidney disease should not apply any herbal remedies without consulting their doctors.
How is Edema Diagnosed in the Body?
To diagnose edema and understand its cause, a physical examination is conducted to check the swelling in body tissues, and medical history is reviewed. In some cases, blood tests, ultrasound examinations, or other tests may be needed.
- When diagnosing edema, specific areas are identified, and pressure is applied to the skin to measure severity.
- The person's medical history is queried; information is obtained regarding health issues and dietary habits.
- Blood tests evaluate kidney functions, thyroid functions, liver enzymes, and electrolyte balance.
- An ultrasound examination may be conducted if vessel-related conditions are suspected.
- If there is edema in the legs, it is examined with a Doppler ultrasound.
- In cases of suspected organ-related issues, imaging tests like X-rays, CT scans, or MRIs may be applied.
How is Edema Treated?
The fundamental principle of edema treatment is identifying the underlying cause and implementing the appropriate medical approach for this cause. While lifestyle changes are often sufficient for temporary edemas, medical treatment is necessary for edemas due to systemic diseases.
If there is an underlying heart, kidney, liver, or thyroid condition, medical treatment is planned based on the specialist's direction. Medications may be used under doctor supervision if deemed necessary. However, uncontrolled use of these medications can lead to serious fluid-electrolyte imbalances and should be monitored by a doctor.
For edemas related to medications or lymphatic drainage disorders, supportive methods such as physical therapy and lymphatic massage may be preferred. Further assessment is needed for unilateral, firm, or prolonged edemas.
Frequently Asked Questions
How long does edema last in the body?
The duration of edema varies depending on the type of underlying cause. Edema due to lack of physical activity, excessive salt consumption, or hormonal changes typically reduces on its own within a few days. However, edemas due to heart, kidney, or liver origin may take longer to resolve and might require medical intervention.
Does every swelling mean edema?
No, not every swelling is related to edema. Trauma, infections, soft tissue disorders, or localized inflammations can also cause swelling; therefore, an assessment should be made considering the type, duration, and accompanying other symptoms of the swelling.
In which areas is edema more frequently observed in the body?
Edema most commonly appears in areas affected by gravity, such as the feet, ankles, and legs. However, in some systemic diseases, edema can also develop in the hands, face, abdominal cavity, lungs, or around the eyes.
Does daily water consumption reduce edema?
Yes, adequate water consumption is effective in maintaining body fluid balance and can help prevent the formation of edema. Dehydration can increase fluid retention.
