What factors cause lower limb edema

Many people sit in the office for a long time, and the indoor temperature is very comfortable. There are air conditioners in winter and fans and air conditioners in summer. Many people do not like to go out, which will cause lower limb edema over time. There are also many middle-aged and elderly friends who have organ failure as they age, coupled with poor excretion, which can also cause physiological edema. These aspects must be considered carefully, and corresponding inspections and judgments must be made.

Lower limb edema can be divided into physiological and pathological types.

As we age, the organs in our body age. Due to the decrease in cardiac output and renal blood flow, the subcutaneous tissue relaxes and the evaporation of water from the skin decreases, resulting in physiological edema.

Pathological edema is often seen in heart and liver diseases, but can also be seen in people with kidney disease or malnutrition.

Edema caused by chronic right heart failure due to heart disease starts from the ankles of both lower limbs and then gradually develops to the whole body. It is more common in coronary heart disease and hypertensive heart disease. When suffering from cirrhosis, the lower limbs will swell first, then ascites will appear, and finally the whole body will swell.

Edema caused by kidney disease starts from the eyelids and face, and is more common in pyelonephritis, diabetic nephropathy, etc. Many patients with prostate hypertrophy and bladder tumors may also experience lower limb edema.

If there is no problem with the heart, liver, or kidneys, it may be deep vein thrombosis in the lower limbs. If there is no problem with these either, then there is no big problem. Lower limb edema is common in the elderly, so don't worry too much.
