Mild renal impairment is caused by these reasons

When renal function is mildly impaired, the symptoms exhibited by the patient are not very obvious and can be easily overlooked. Studies have found that there are many reasons for this symptom, the most common ones include excessive use of Chinese herbal medicines that damage the kidneys, abuse of Western analgesics, frequent urine holding, and drinking too little water.

1. Abuse of Chinese herbal medicines that damage the kidneys

In recent years, clinical studies have repeatedly found that taking certain Chinese herbal medicines (including Chinese patent medicines) can cause renal damage. Chinese herbal medicines that can "damage the kidneys" include: Tripterygium wilfordii, Aristolochia ternata, Pharbitis chinensis, Xanthium sibiricum, Poppy shell, Raw Aconitum, Quisqualis chinensis, Aucklandia lappa, Stephania tetrandra, etc. Among them, Tripterygium wilfordii causes the greatest kidney damage, followed by Aristolochia chuanxiong. The reason Aristolochica chuanxiong damages the kidneys is that it contains the nephrotoxic substance aristolochic acid.

2. Abuse of Western analgesics

Long-term or large-dose use of some anti-inflammatory and analgesic drugs, such as painkillers, indomethacin, paracetamol, aspirin, etc., can easily cause kidney damage. Kidney damage may manifest as fatigue, dry mouth, loss of appetite, frequent urination, urgency, pain when urinating, and even hematuria and sterile pyuria, accompanied by joint pain and other symptoms. Some can directly cause nephrotic syndrome such as acute nephritis or glomerular necrosis, and in severe cases can lead to renal failure and death.

3. Frequently holding urine

Some people hold their urine for a long time because of their busy work. If urine stays in the bladder for too long, bacteria can easily multiply and travel back through the ureters to the kidneys, causing urinary tract infection and pyelonephritis. Once this type of infection recurs, it can cause a chronic infection that is difficult to cure. Patients will not only experience symptoms such as back pain, frequent urination and urgency, but may also develop acute uremia.

4. Drinking too little water

If you don't drink water for a long time, the amount of urine will decrease and the concentration of waste and toxins carried in the urine will increase. Common clinical conditions such as kidney stones and hydronephrosis are closely related to not drinking water for a long time. Drinking enough water can dilute urine, protect the kidneys, and help fully excrete waste and toxins.

5. Overeating

Modern people have more opportunities to have dinner together, and they often eat too much "delicacies". The food they eat will eventually produce waste products - uric acid and urea nitrogen. Most of these wastes are excreted through the kidneys, and excessive eating will undoubtedly increase the burden on the kidneys.

6. Excessive drinking of beverages

Excessive intake of soft drinks and sports drinks can indirectly damage the kidneys. The pH value in the human body is 7.2. These beverages are generally highly acidic, and the pH value in the body changes significantly after drinking them. The kidneys are the main organs that regulate the acidity and alkalinity of the human body. Long-term excessive intake of soft drinks and sports drinks will put a burden on the kidneys and increase the probability of kidney damage.

7. Eating bread that is too soft

Potassium bromate is a food additive in bread and pastries. It can give baked foods the necessary gluten strength and elasticity, making them taste soft. However, excessive consumption can damage the human central nervous system, blood and kidneys.

Potassium bromate, a food additive, has been listed as a carcinogen by the International Agency for Research on Cancer.

8. Eating too salty food

A salty diet, especially certain snacks with too high salt content, such as potato chips, instant noodles, etc., will cause people to absorb excessive salt unknowingly, leading to high blood pressure, and the kidneys cannot maintain normal blood flow, thereby inducing kidney disease.

9. Drink strong tea after drinking

Some people believe that drinking strong tea after drinking alcohol can help them sober up. In fact, this is not only ineffective, but can also damage the kidneys. The caffeine in tea can quickly affect the kidneys and exert a diuretic effect. At this time, the alcohol has not yet had time to be broken down and is excreted from the kidneys, causing the kidneys to be stimulated by a large amount of ethanol, thereby damaging kidney function.
