What is the reason for thigh swelling

Many people's legs become red, swollen and edematous for no apparent reason. This may indicate a kidney problem, because kidney tissue is an important organ for the body's water excretion. When kidney disease occurs, the patient's water excretion function decreases, which leads to swelling in the body. You need to go to the hospital to check the cause. When some mild physical symptoms appear, it may indicate that there is a problem with the organ.

Leg swelling may indicate kidney disease

Kidney tissue is an important organ for the body's water excretion. When kidney disease occurs, the patient's kidney's ability to excrete water decreases, causing the body's ability to maintain a balanced water circulation system. The water in the body cannot be excreted smoothly for a long time, causing edema, of which leg edema is one of its important manifestations.

Therefore, leg swelling may be a sign of kidney disease. Leg swelling caused by kidney disease often worsens after fatigue and improves after rest, and often appears after swelling of the eyes and face.

In the early stages of kidney disease, patients often do not have leg edema, but only mild eyelid edema, which is hidden edema. Generally speaking, mild leg edema will decrease or disappear after the patient rests. Severe leg edema will manifest itself in the lower limbs and ankles, where pressing with fingers will leave a concave feeling, and edema may even occur all over the body.

If you suspect that the leg edema is caused by kidney disease, you can go to a regular hospital for a routine urine test. You can also do a kidney function test and a renal B-ultrasound examination, which will help determine whether there is a problem with the kidneys and rule out the possibility of kidney disease in a timely manner.

After leg swelling occurs, what symptoms highly warn of the possibility of kidney disease?

1. Observe urine to determine whether the kidneys are healthy

Urine protein: There is a lot of foam in the urine, which does not disappear for a long time. This indicates that there is a lot of protein excreted in the urine. A routine urine test can help further determine whether it is proteinuria.

Urine color: Urine is dark tea color, meat washing water color, soy sauce color or turbid.

Urine volume: Too much or too little urine. The average normal urine volume is 1500 ml per day, 4-8 times a day. If the amount of urine suddenly decreases or increases without fever, excessive sweating, or drinking a lot of water, you need to check your kidney function.

Nocturia: Normal people do not experience nocturia before the age of 60. If young people experience increased nocturia, it may be an early sign of poor kidney function.
