Men go to the toilet 'for the first time' in the morning. If there are no three symptoms, it means that the kidney function is not bad

The kidneys play a big role in helping our body detoxify. The kidney referred to in Western medicine is a solid organ, one on the left and one on the left, shaped like a broad bean, and located on both sides of the spine. It is where urine is produced and body waste is eliminated. When lesions occur, such as nephritis, renal failure, kidney stones, etc.

01 What is the main function of the kidneys?

1. Produce urine metabolic waste.

The kidneys excrete nitrogenous products such as urea, creatinine, and creatine. Otherwise, these urea, creatinine and creatine will accumulate in the body, leading to poisoning and even uremia. The average daily urine output of a normal person is 1500-2000 ml.

In order to maintain normal excretory function, renal blood flow is generally kept in a constant range, and the glomerular filtration rate is about 120ml/min. The kidneys have their own regulatory functions. Renal plasma flow is regulated by glomerular feedback, renal nerves, and vasoactive substances, and the glomerular filtration rate remains within a certain range.

2. Endocrine function.

The kidney is the most important endocrine organ of the human body, which can produce and secrete. When the kidneys are insufficiency, it can lead to insufficiency of vitamin D activity and corresponding diseases. When the kidneys are damaged, the above-mentioned vasoactive substances may be out of balance, leading to increased blood pressure. The kidney can also secrete a variety of cytokines, which play an important role in regulating life activities.

The kidney itself can produce renin, which then has a certain auxiliary effect on the maturation and production of red blood cells. At the same time, it also produces active vitamin D and prostaglandins.

3. Maintain fluid balance and acid-base balance in the body.

Through glomerular filtration, renal tubular reabsorption and secretion functions, the kidneys excrete excess water from the body, regulate the acid-base balance, and stabilize the external environment.

The examination revealed a kidney problem. Of course, the kidneys can be involved in acid-base balance. The main principle of kidney regulation of acid-base balance is to regulate acid-base balance by secreting hydrogen ions, false collars and ammonia ions. At the same time, it is also reabsorbed to retain water and glucoprotein.

02 If there are no three symptoms, go to the toilet, if there are no three symptoms, or the kidney function is good.

There is foam in the urine.

Usually the surface tension of the urine is very low, and the foam in the urine varies in size and disappears quickly, mainly for physiological reasons. If the foam in the urine is small and does not disappear for a long time, it may be a pathological cause, and medical examination should be carried out to confirm the diagnosis and treatment.

Generally, urine is light yellow and transparent. According to normal urine, there should be no foam, mainly because the surface tension of urine is very strong and there is less foam. But if the urine contains some organic and inorganic substances, the urine tension will be weakened and some foam will appear.

2. Urine yellow.

The physiological cause of yellow urine is that the patient drinks too little, sweats too much, or gets angry. Patients can eat more heat-clearing and detoxifying foods and drink more water, and the symptoms can be relieved after a few days. In addition, taking vitamin E or other drugs can also cause yellow urine.

Urinary tract infection, diabetes screening, STD screening, glomerular disease, kidney cysts, stones, benign prostatic hyperplasia, urinary tract infection and tumor screening may also be performed. In general, infections and stones are the most likely and most common. Drink plenty of water clinically, don't be too nervous.

3. Poor urination.

Urinary obstruction is a very common disease in clinical practice. In patients with dysuria, it can be male or female, and in males, it can be an elderly man or a young and middle-aged man. If the urine is not smooth in women, it may be a urinary tract infection, such as urethritis, cystitis, etc.

If the urine in the bladder is blocked during the discharge process, causing the urine to be blocked from the bladder, it will cause symptoms of poor urination. Depending on the cause of the obstruction.

03 What are the common kidney diseases?

1. Kidney failure

Renal failure refers to abnormal kidney function. Acute renal failure refers to the rapid decline of renal function in a short period of time, manifested as elevated serum creatinine, elevated blood urea nitrogen, hyperkalemia, and acidosis. There are many causes of acute renal failure, after controlling it.

Chronic renal failure is often associated with basic kidney diseases such as chronic nephritis, diabetes, and hypertension, and manifests as elevated blood pressure, nausea, and vomiting.

2. Uremia

Uremia generally refers to the late stage of chronic renal failure, namely, stages 4 and 5 of chronic renal failure. During this period, the patient's kidneys cannot function normally, which can lead to disturbance of water, electrolyte, acid-base balance, and possible endocrine dysfunction.

A series of symptoms and signs is called uremia. Uremia is the end-stage manifestation of renal failure. There are many reasons for it. As long as it can damage the glomerulus, renal tubule, renal interstitium, and renal blood vessels, it will lead to the occurrence of uremia.

3. Pyelonephritis.

Pyelonephritis is a urinary tract infection, divided into upper urinary tract infection and lower urinary tract infection. Upper urinary tract infections include pyelonephritis, ureteritis, cystitis, or urethritis.

The most common bacteria causing urinary tract infection is Escherichia coli, which has a higher incidence in women and is mainly closely related to the female urinary anatomy, urethra and anus distance.

4. Kidney tuberculosis

Renal tuberculosis is usually secondary to tuberculosis lesions elsewhere in the body, which is the most common and first occurrence of urinary tuberculosis, and can then spread from the kidneys to the entire urinary system. Kidney tuberculosis mainly occurs in adults. 75% of China's comprehensive statistics occur between the ages of 20-40, but it can also occur in teenagers and the elderly. The incidence is slightly higher in men than in women.

5. Nephritis

Nephritis is a group of clinical syndromes with proteinuria, hematuria, edema and hypertension as clinical manifestations. Based on the patient's medical history and laboratory test results.

Divided into acute glomerulonephritis, chronic glomerulonephritis and occult nephritis. There are many causes of nephritis. Nephritis mentioned here usually refers to primary glomerulonephritis, of which a small percentage is secondary.

04 How to nourish the kidneys and protect the kidneys?

First of all, we should actively participate in physical exercise, strengthen our physique, maintain enough sleep, and avoid staying up late. Usually, the diet must be balanced, with meat and vegetables, avoid spicy, cold, fat, sweet and greasy food to reduce the burden on the gastrointestinal tract; eat more black foods, such as black rice, black beans, black fungi, kelp, black sesame seeds, etc.

Men and women alike. For the kidney essence, pay attention to solidification, do not overindulge, this will cause great damage to the kidney essence. The waist is the home of the kidneys, and the function of the kidneys is largely reflected in the waist, so it is very important to protect the waist. For example, keep warm in winter, don't live in wetlands for a long time, and don't lie on cool ground, so as to avoid cold pathogens causing damage to kidney yang.
