In our daily life, there is such a part of the population, often covering the waist, jokingly saying that their kidneys are not good, I just want to ask everyone: how much do you know about kidney disease in the end? I think most people are half-knowledge, or even a general lack of knowledge, there are many patients in the body without obvious changes in the premise is not to go to the hospital to do the appropriate examination, because in their subconscious, this refers to the temporary, so always in the aggravation of the disease in the attention, the result is found that the kidney disease has been very heavy, life-threatening, and even need immediate hemodialysis. Here, I especially point out: many diseases have a certain insidious nature, the next 12 significant characteristics to you, you can self-test, if you accidentally on the right, we must promptly carry out relevant checks, responsible for themselves. 1, no energy. When the kidney function is not good, many wastes are difficult to excrete from the urine, there will be a lack of energy, fatigue, fatigue and other feelings of no energy. Kidney disease, protein and other nutrients leak from the kidneys, through the urine out of the body, will also have no energy performance. Some patients will think it is overworked, or other reasons, and ignore the kidney problems. 2.Do not want to eat. Not wanting to eat, anorexia, or even nausea and vomiting are also common symptoms of kidney disease. Some patients always go to the gastroenterology or hepatology department first, to see if they have stomach disease or liver disease, look at no stomach disease and liver disease, set aside regardless, forget to see a kidney doctor, the results delayed the disease. 3, urine with foam. There are various reasons for foam in urine, among which if protein leaks from the kidneys into the urine, the urine will foam a lot. 4.Back pain. The kidneys are located on both sides of the spine in the waist, so when the kidneys are sick, you will feel back pain. 5.Piss more and piss less. A healthy person urinates about 4 to 6 times a day, and the volume of urine is about 800 to 2000 ml. If the number of urination and the volume of urine are too much or too little, you should pay attention to it. 6, edema. Drinking too much water, or sleeping too long, too obese, etc., the eyelids, face, calves and other parts of the body can appear a slight edema, or a transient edema, if not, we should suspect whether the kidneys have a problem. 7. Urine protein and urine occult blood. The presence of protein or occult blood in urine is an important indication of kidney disease, which can be clarified by a routine urine check. However, sometimes non-nephrologists may overlook this point, so it is best to consult with a nephrologist. 8.Anemia. Patients with anemia often go to the hematology department to see anemia. In fact, besides excreting waste, the kidneys also have endocrine functions and secrete hematopoietic hormones, which can also cause anemia when kidney function is damaged. 9.Diabetes. Diabetes can cause kidney disease, and it is called diabetic nephropathy, which is a complication of diabetes. Diabetic nephropathy is divided into five stages, in the early stage when the treatment is better, once late, it is very difficult to cure, it will develop into uremia. Therefore, diabetic patients, must always look at nephrology. 10, hypertension. Hypertension can cause hypertensive nephropathy, also called hypertensive kidney damage, so people with hypertensive disease should pay more attention to it. Of course, kidney disease can also cause high blood pressure, blood pressure if high, beware if you have kidney disease. 11, gout, hyperuricemia. Gout and hyperuricemia are caused by too much uric acid in the blood, and people with high blood uric acid will have uric acid deposited in the kidneys, which will damage the kidney function. 12, urinary tract infections. People with frequent urinary tract infections, over time, may cause renal insufficiency. I have contacted many patients with urinary tract infections, because early treatment is not timely and complete, and do not understand that it will lead to poor kidney function, and as a result, when found, the best time to treat has been missed.
