How to maintain the kidneys

 The two kidneys are located on both sides of the spine below the rib cage, and the size of one kidney reaches the size of a fist, and one kidney contains approximately one million renal tubular units, which together help to filter blood, and this unit consists of small blood vessels known as glomeruli, which in turn help to Filtering blood from waste products by removing chemicals and excess water from the blood, and it is a great creation of God that the kidneys filter approximately 200 liters of fluids per day so that approximately two liters of these fluids are disposed of in the form of urine, and the remaining part is reabsorbed again.

Preserving the kidneys:

Where there are many methods and tips that can be followed to maintain the integrity of the kidneys, and it should be noted that most kidney diseases do not lead to the emergence of clear symptoms on the affected person, which leads to the development of the disease without the person feeling that, and that is why it is called the silent killer. Most of these diseases can be prevented by adopting a healthy lifestyle and some other healthy habits, and the following is a list of some ways to preserve the kidneys:


Exercising for 30 minutes a day for most days of the week helps lower blood pressure, which in turn helps reduce the risk of developing chronic kidney disease.

 Control the level of sugar in the blood:

 This occurs by monitoring the level of sugar periodically, as high blood sugar increases the risk of developing chronic kidney failure, and therefore regular monitoring of the level of sugar contributes to early detection of diabetes and its good control before health complications arise.

Blood pressure monitor:

Where high blood pressure can cause stroke, or heart attack, in addition to some kidney diseases, especially if it coincides with suffering from other chronic diseases such as diabetes.

 Follow a healthy diet:

Where a healthy diet helps to prevent diabetes, heart disease, and other diseases associated with chronic kidney failure, and includes a healthy diet, including reducing the proportion of salt used in food, and trying to replace it with various spices for cooking, and eating fresh fruits and vegetables And reducing the proportion of sugars in the food, so that these sugars constitute less than 10% of the daily calories. Roasting cuts of meat, poultry, and fish, instead of frying them, eating low-fat milk or skimmed milk, and eating foods that contain whole grains such as whole wheat, whole rice, oats, and corn, on a daily basis.

Drink enough fluids:

Where drinking an adequate amount of fluid helps the kidneys remove sodium, urea, and toxins from the body, which leads to reducing the chance of developing kidney disease, and it is recommended to drink approximately two liters of water on a daily basis, and it should be noted that the amount of fluids that should be consumed may vary according to the level of The physical activity practiced by the individual, the climate, the health status of the individual, pregnancy, and breastfeeding. Patients suffering from kidney stones are advised to drink 2-3 liters of water daily to reduce the chance of new stones.

Quit Smoking:

Smoking helps reduce blood flow to the kidneys, which impairs their ability to purify the blood from waste and toxins, and smoking increases the risk of kidney cancer by about 50%.

 Avoid taking over-the-counter medications too often:

NSAIDs, such as ibuprofen, increase the risk of kidney damage if taken regularly, so you should consult your doctor before using these drugs to treat chronic pain such as arthritis or back pain.

Get enough sleep:

Sleeping hours range from 7-8 hours a day, and abstaining from alcohol, as alcohol consumption contributes to high blood pressure and weight gain, which increases the risk of developing kidney damage.

What is the function of the kidneys:

Where the kidneys perform many important and vital functions in the human body, and among these functions we mention the following:

  1. Manufacture of calcitriol, the active form of vitamin D, which increases the level of calcium in the blood by stimulating its absorption from the intestine.
  2. Eliminate waste products such as urea and uric acid through the urine.
  3.  The reabsorption of nutrients such as glucose, amino acids, bicarbonate, sodium, water, phosphate, magnesium and potassium.
  4.  Maintaining the blood pH. Regulating blood pressure.
  5. The production of the hormone erythropoietin, which regulates the production of red blood cells, also plays an important role in wound healing and the response to nerve cell injury.
  6.  Secretion of the hormone renin, as this hormone helps expand arteries and increase the volume of blood plasma.

To prevent kidney failure:

  •  To drink adequate quantities of water daily, that is, no less than two liters on a regular day, and more on a hot day.
  • Avoid drinking sweetened juices and soft drinks, as they are harmful to the kidneys.
  • Eat fresh vegetables and fruits on a regular basis, that is, at the rate of two meals a day. Reducing the intake of sugars, fats and starches.
  •  Doing exercise periodically, that is, at least three times a week for a half hour each time. Get enough sleep. Conducting regular medical examinations for the kidneys, especially when taking medications that affect kidney function as a side effect.
  •  Not to neglect any symptoms indicating problems in the urinary system, such as a change in the color of the urine, or a burning feeling when urinating, and these are evidence of infections that can spread and reach the kidneys.

  • Maintaining an ideal weight, or at least a moderate one, as excess obesity puts pressure on the kidneys. Avoid smoking, as it contains many toxins that reach the kidneys. Not to drink alcohol as it exhausts the kidneys while purifying the blood from its effects.
  •   Take calcium and oxalic acid in reasonable amounts, as they can combine together to form what is known as sand and kidney stones. For diabetics, care must be taken to maintain a moderate level of blood sugar permanently, as high blood sugar for a long time leads to kidney failure and other serious diseases.
