What are the symptoms of edema? What causes the edema

Edema is the condition of edema in certain parts of the body, usually appearing on the eyelids, face and limbs, and may even appear in the whole body, accompanied by pleural effusion and ascites. The edema is different because of the **, and it will be accompanied by other symptoms, such as edema caused by kidney disease, and the patient will also feel backache and increased urine foam. If edema is caused by heart disease, symptoms of palpitation, chest tightness, and arrhythmia often occur.

If the edema is caused by abnormal thyroid function, the patient may also experience chills and fatigue. If it is due to edema caused by liver disease, it may even cause symptoms such as vomiting, loss of appetite, and nausea.

Condition analysis: The symptoms of edema are swelling of the head and face, puffiness of the eyelids, edema of the limbs and even edema of the whole body. The causes of edema are mainly related to kidney, heart, and liver lesions, but may also be related to malnutrition or regional lymphatic system lesions.

Timely primary disease, combination of work and rest, pay attention to rest, the increase of metabolites in the body after fatigue will increase the burden on the kidneys, and also reduce the body's resistance.

This kind of thing looks like the hands and feet are swollen, and it's a pit when you press it. Recovery is slow.

The mechanism of edema is as follows:

1. Sodium and water retention; 2. Increased capillary filtration pressure; 3. Increased capillary permeability; 4. Plasma colloidal osmotic pressure decreases; 5. Lymphatic fluid reflux is blocked.

Common causes of tissue edema are:

1. Cardiogenic edema - heart failure, constrictive pericarditis;

2. Nephrogenic edema - acute and chronic nephritis, nephrotic syndrome;

3. Hepatic edema - liver cirrhosis, liver necrosis;

4. Dystrophic edema - anemia, cancer, burns (hypoproteinemia);

5. Drug-induced edema - corticosteroids, etc.;

6. Edema of pregnancy - Pregnancy toxicity can cause edema, proteinuria, hypertension, etc.

7. Endocrine disease - myxedema caused by hypothyroidism.

8. Localized edema - common in inflammation, trauma, allergies, compression and other reasons, resulting in obstruction of venous and lymphatic return or increased capillary permeability.

9. Idiopathic edema (functional) - edema without a clear cause, such as premenstrual tension syndrome. Hey hey

Many people with kidney disease will be confused about the problem that when they have kidney disease, the human body will have edema. Edema is caused by the accumulation of body fluids in the spaces between the tissues outside the blood vessels of the body. In most cases, the most common cause of edema is sodium and water retention.

So,?According to different ways, edema can be divided into: 1. Pitting edema and non-pitting edema.

Pitting edema is caused by the accumulation of fluid in the space of the connective tissue under the skin, whereas nonpitting edema is caused by chronic obstruction of lymphatic return (e.g., filariasis elephantiasis). 2. Generalized edema and localized edema. Generalized edema is edema that occurs under the skin all over the body, while localized edema is edema in one part of the body.

3. Inflammatory and non-inflammatory edema. Inflammatory edema is often accompanied by local redness, swelling, burning, and pain, and is absent from non-inflammatory edema. The causes of generalized edema are cardiogenic, renal, hepatic, nutritional, and idiopathic; The causes of localized edema are local inflammation, venous thrombosis, filariasis, angioedema, etc.

Different causes of edema have different clinical manifestations: idiopathic edema is a special type of generalized edema, which is almost only found in women, especially middle-aged women. The most obvious area of edema is double lower swelling, which is characterized by no or mild edema in the morning, and then gradually worsens, most so at bedtime, and disappears or decreases after lying flat overnight.

Apart from edema, there was no other discomfort. The cause of this edema is unknown, but the prognosis is good. Localized edema is mostly associated with certain diseases, such as rheumatoid arthritis, in which edema may occur at the joint with local congestion, fever, and pain; In venous thrombosis of the lower extremities, there may be edema of the affected limb; Angioedema is associated with allergies.

Generalized edema should pay attention to the characteristics of edema and the underlying disease. Generally speaking, if edema has been caused by diseases such as heart, liver, and kidney, the disease has reached a very serious level, so the diagnosis is not very complicated. If the general condition is good, and there is no cause of heart, liver, kidney disease or malnutrition, it may be considered idiopathic in female patients.

The cause of localized edema is not very difficult to diagnose because it is relatively closely related to a disease, depending on the comorbid symptoms and certain necessary tests.
