Characteristics of kidney is not good: 1. Less menstrual flow, or short menstrual period, dark color. The appearance and disappearance of menstruation are both manifestations of whether renal function is strong or not. If there are many renal toxins, menstrual blood will decrease.

2. edema. The kidneys manage fluid movement in the body. After the accumulation of toxins in the kidney, the ability to discharge excess fluid is reduced and edema occurs.

3. Mandibular acne. The mandible of the face belongs to the jurisdiction of the kidney, and the kidney's detoxification is insufficient, and excess toxins will be displayed in the mandible.

4. Get tired easily. Toxins in the body consume the energy of the kidney, and the energy provided by the kidney is reduced, so physical fatigue, lethargy and limb weakness occur.

Renal protective measures: 1. Drink more water: People who drink less water and urinate less are prone to kidney calculi, and kidney calculi will affect renal function. Drinking 8 glasses of water every day, eating less chocolate, strawberries, nuts, spinach, iced tea and instant coffee, and supplementing more vitamin B6 can reduce the generation of calcium oxalate in urine, thus reducing the occurrence of kidney calculi.

2, eat more black food: black food such as fungus, mushrooms, etc., can ensure the metabolism of the kidney and reduce the accumulation of excess water in the kidney. Chestnut also has the effect of tonifying kidney and strengthening waist, and you can achieve your goal by eating 6~7 a day.

3, eat more plant protein: the diet should be light, not too salty, eat less high-protein and high-fat food, because hyperlipidemia will cause renal arteriosclerosis, leading to renal function damage; Excessive food intake in protein will increase the burden on the kidneys. Eat more tofu and beans. Even patients with kidney disease or chronic renal failure can eat some beans properly. Because vegetable protein is beneficial to the kidney, and soybean contains phytoestrogen, which has the function of protecting the kidney.

4 Don't use drugs indiscriminately: The most common drugs that damage the kidneys include various painkillers, antibiotics such as gentamicin, kanamycin and sulfonamides. Diabetic patients, the elderly and those with mild renal function decline are more prone to drug poisoning.

5, pay attention to the type of urination: keep urine unobstructed, urine unobstructed. Attention should be paid to the pattern of urine, which can reflect renal function. For example, foam urine is a manifestation of proteinuria, and nocturia is an early symptom of renal insufficiency. If there is urethral obstruction and poor urination, it will increase the chance of nephritis and increase the burden on the kidneys.

6. Prevent common diseases that may cause kidney diseases, such as upper respiratory tract infection, hypertension, diabetes, obesity, etc. Upper respiratory tract infection, especially pharyngeal inflammation, is often the main factor that causes kidney diseases, and it is also one of the factors that cause recurrent kidney diseases. Preventive measures should be taken. Hypertension makes renal blood vessels harden under high pressure for a long time, which is harmful to renal function; Obesity will increase the burden on the kidneys and lead to renal function damage. 30% of diabetic patients will develop uremia, so it should be effectively controlled. In addition, arteriosclerosis, hyperlipidemia and so on. It will lead to kidney function damage, and we should be careful.

7. Regular renal function examination: those who have family history of kidney disease, hypertension, diabetes and nephritis when they are young are all high-risk groups of chronic renal failure. Therefore, when they suffer from this kind of disease, they should check their renal function regularly for early detection and treatment.
