Some people feel that their bodies are “always healthy”, and when they feel obviously unwell, they are diagnosed with uremia, which has lost the time for early treatment, bringing obvious pain to themselves and even life-threatening, and bringing a huge economic burden to their families and society. So, how can kidney disease be detected early? For example, the following conditions occur: Edema: Eyelid or facial edema in the morning, which mostly subsides in the afternoon, worsens after exertion and decreases at rest. In severe cases, edema may appear in low hanging areas, such as both ankles, both lower limbs, and the sacrococcygeal region. Increased urinary foam: If there is still more foam after the urine has been left for a period of time, it indicates excessive protein excretion in the urine. Abnormal urine color: Normal urine color is light yellow and transparent, if the urine color is thick tea, wash water color, soy sauce color or cloudy like rice water, you should immediately see a doctor to determine the cause. Urine volume is too much or too little: normal daily urine volume is about 1500 ml, if there is no drink too little water, sweating, fever, diarrhea and other factors urine volume suddenly reduced should be abnormal. Urine volume of more than 2500 ml per day should be examined to determine whether the kidneys and other diseases. Increased nocturia: Normal people younger than 60 years of age generally should not have nocturia. If there is an increase in nocturia, it may be an early sign of kidney insufficiency. Pallor: Many causes can lead to anemia, mainly manifested as pallor, and kidney disease is the more common cause of anemia. Hypertension: Chronic kidney disease developed to a certain stage can lead to hypertension, while hypertension developed to a certain stage can also lead to kidney damage, and the two affect each other. Therefore, when hypertension occurs, it should not be taken lightly and should be promptly examined and actively treated by kidney-related examinations. Low back pain: Kidney stones, acute nephritis, acute pyelonephritis, kidney tumors, etc. can cause low back pain. You should consult a doctor promptly and describe in detail the specific location, time of occurrence and nature of the pain so that the doctor can examine and diagnose you and provide you with timely and effective treatment.
