Traveler's edema

Introduction Long-term car rides can cause swelling of the lower extremities, which is medically known as "traveler edema." Therefore, don't always sit while riding, you should always change your position to help the blood flow back. Traveler edema is more common in people over 40 years old and in body fat, more common in women, it is a kind of benign edema. It is characterized by numbness, swelling and heavy feeling of the hands and feet. The edema is more common and slack in both lower extremities, and the hands are often involved; most of them are mild edema, and have little relationship with the feeding water; the edema can completely disappear after rest and position change, often It disappeared in the morning for the morning.

Cause

Causes of traveller edema:

1. Due to long-distance travel by train or walking, due to gravity, lower extremity and sagging upper extremity venous return is limited, increasing the hydrostatic pressure of capillaries, resulting in fluid accumulation in the subcutaneous tissue space.

2. Due to increased aldosterone secretion during erect, resulting in increased renal tubular reabsorption of sodium. More common in women, may be related to endocrine disorders; obese people often see more fat because of the need to rely on peripheral blood vessels to dilate body heat, promote lower extremity venous pressure, increased capillary filtration pressure. As long as the traveler's edema stops, it can be recovered in 2 to 3 days without medication. Sometimes the salt intake can be appropriately restricted. The water does not need to be strictly controlled. When the edema is significant, a small amount of hydrochlorothiazide can be used. Each time 25mg (1 tablet) twice a day, even for a few days, the edema can subside. .

Edema is often one of the important manifestations of certain diseases. It can cause more than 30 causes of edema, the most common cause is heart, liver and kidney diseases. However, some patients with edema have no abnormal findings after extensive examination and testing, and after long-term observation, the health of these people is not significantly affected. In view of the reason and nature of such edema, it is not well understood. It is benign edema, also known as functional edema.

Differential diagnosis

Differential diagnosis of traveler edema:

1. Malignant edema: an acute, traumatic, and toxic infectious disease caused by a variety of animals caused by shuttle seedlings. It is characterized by gas edema in the diseased tissue, accompanied by fever and systemic toxemia. The pathogen of malignant edema is mainly Clostridium spp. Clostridium oxysporum, Clostridium perfringens, and soaked tissue seedlings can also cause disease or participate in disease. Clostridium spp. is a blunt, anaerobic crude bacillus at both ends. It is easy to form spores in vivo and in vitro, and the spores are in the center of the corpus callosum, making the cells spiral. Clostridium spp. can produce four toxins of , -toxin is lecithin, which has necrosis, lethality and hemolysis; p-toxin is deoxyribose, which has the function of killing white blood cells; and toxin have hyaluronic acid respectively. Enzyme and hemolysin activity. These toxins increase vascular permeability, cause inflammatory edema and necrosis of the tissue, and can cause lethal toxemia after absorption of the toxin. Clostridium spp. is widely distributed in nature, its spore resistance is very strong, and general disinfection drugs are difficult to work in the short term.

2, high temperature edema: high temperature edema: in the hot summer, often mild edema of the hands and feet after outdoor activities.

3, systemic persistent edema: systemic persistent edema refers to excessive body fluid accumulation in the extracorporeal extravascular tissue, which is one of the common clinical symptoms. Edema is a manifestation of systemic gasification dysfunction, and is closely related to the lungs, spleen, kidney, and trifocal organs. According to the different symptoms, it is divided into Yangshui and Yinshui. It is common in nephritis, pulmonary heart disease, liver cirrhosis, nutritional disorders and endocrine disorders.

4, lower extremity edema: divided into physiological edema and pathological edema. Lower extremity edema is common in clinical practice, mainly seen in the following diseases. 1 heart edema, suffering from a variety of heart disease patients, when the heart is insufficiency, systemic dysfunction, so that the lower extremity venous return to reduce blood volume, causing edema; 2 hepatic edema, various liver cirrhosis, due to liver synthesis of albumin Reduce, cause hypoproteinemia, lower plasma osmotic pressure, can cause plant limb edema; 3 renal edema, acute and chronic, nephritis or nephrotic syndrome patients, glomerular filtration function is reduced, causing water retention in the body, in addition Coupled with a large amount of proteinuria, resulting in hypoproteinemia, resulting in edema; 4 hypothyroidism edema, hypothyroidism, patient dermal layer of mucopolysaccharide deposition, intercellular accumulation of a large number of transparent garden, chondroitin sulfate and Moisture can cause lower extremity edema; 5 lower extremity deep venous edema, lower extremity deep phlebitis or lower limb venous insufficiency, due to venous return obstruction, patients may have lower extremity edema.
