Growing up, Zhang Xiaoming had a strong interest in medicine, which inspired him to become an internist.
One day, his friend Li Ming suddenly came to him for help, saying that he had been feeling sore in his lower back recently, and the color of his urine had become cloudy. Xiaoming decided to take Li Ming to the hospital for an examination in person.
At the hospital, Li Ming had routine urine and blood tests and an ultrasound.
The results showed that he had obvious stones in his kidneys, and the creatinine and urea nitrogen levels in his blood were also higher than normal, and the preliminary diagnosis was kidney stones combined with mild renal insufficiency.
As an experienced doctor, Xiaoming realized the seriousness of the problem and decided to learn more about Li Ming's lifestyle habits to find out the possible triggers.
Through detailed inquiry, Xiaoming found that Li Ming usually likes to drink tea very much, especially strong tea, and drinks at least five or six cups a day.
This habit caught Xiaoming's attention. Remembering some research I had read in the medical literature on the relationship between tea and kidney disease, I decided to further analyze Li Ming's situation.
Tea leaves, especially green and black teas with high amounts of oxalic acid, do have the potential to increase the risk of kidney stone formation. Calcium oxalate is one of the main components of kidney stones, and the oxalic acid contained in tea increases the formation of calcium oxalate crystals.
In addition, the caffeine in tea may also have a certain stimulating effect on the kidneys. Xiaoming explained these principles in detail and reminded Li Ming of the importance of drinking tea in moderation.
"Tea itself has many health benefits, such as antioxidants and anti-inflammatory, but excessive consumption can be harmful to the kidneys," he says.
Especially for people like you, who drink a lot of strong tea every day, you need to pay more attention to the problem of excessive oxalic acid intake. ”
Studies have shown that drinking tea in moderation has health benefits, especially certain types of tea such as green tea, white tea, and certain herbal teas, which are rich in antioxidants that can help lower blood pressure and improve kidney function.
However, excessive consumption of tea leaves, especially those high in oxalic acid, may increase the risk of kidney stones.
The oxalic acid in tea leaves can form crystals in the kidneys, leading to the formation of kidney stones. In addition, the caffeine in tea may also have a certain stimulating effect on the kidneys, increasing the burden on the kidneys.
Oxalic acid content: Oxalic acid is an organic acid that occurs naturally in many plants. In the kidneys, oxalic acid can combine with calcium to form calcium oxalate crystals, which in turn form kidney stones.
Tea contains a certain amount of oxalic acid, especially green and black tea, and excessive consumption may increase oxalic acid intake, which can increase the risk of kidney stones.
Caffeine: Caffeine is a central nervous system stimulant that is widely found in tea, coffee, and some energy drinks.
Moderate amounts of caffeine can improve alertness and concentration, but excessive intake may adversely affect the kidneys.
Caffeine can increase the production of urine, which leads to the loss of water from the body, which in turn increases the burden on the kidneys.
Tea polyphenols: Tea polyphenols are a natural antioxidant in tea that has anti-inflammatory, antioxidant, and cardiovascular system protective effects.
Studies have shown that moderate intake of tea polyphenols has a certain protective effect on kidney health. However, excessive intake of tea polyphenols may have negative effects on the kidneys and increase the risk of kidney stones.
In the treatment plan for Li Ming, Xiaoming especially emphasized the importance of reasonable tea drinking.
It is recommended that Li Ming control the amount of tea he drinks every day and choose teas with low oxalic acid, such as white tea and certain herbal teas (such as peppermint tea and chamomile tea). These teas are not only harmless to the kidneys, but also have certain health benefits.
In addition, Xiaoming also advised Li Ming to increase his daily water intake to promote urine production
and excretion, thus helping the kidneys to excrete metabolic waste products and calcium oxalate crystals.
He also emphasized the importance of a balanced diet, suggesting that Li Ming consume more foods rich in fiber, vitamins and minerals, and reduce a high-salt and high-protein diet to reduce the burden on the kidneys. Xiaoming decided to further explore the relationship between tea and kidney disease in order to better advise patients.
A large number of medical literature and research materials were reviewed, and many research results on the relationship between tea and kidney disease were found.
One study has shown that drinking green tea in moderation is beneficial for kidney health and can reduce the risk of chronic kidney disease (CKD).
This study analyzed genomic broad association study (GWAS) data and found that drinking an extra cup of green tea per day significantly reduced the risk of CKD and improved the estimated glomerular filtration rate (eGFR) (Frontiers).
Other studies suggest that different types of tea may have different effects on the kidneys.
Compared with green tea and black tea, oolong tea and white tea have a lower oxalic acid content, which is more suitable for patients with kidney disease. Additionally, some herbal teas such as chamomile tea and peppermint tea are also believed to have a protective effect on the kidneys, which can help lower blood pressure and reduce inflammation in the kidneys.
However, some studies have also pointed out that certain tea leaves such as black tea and strong tea are high in oxalic acid, and excessive consumption may increase the risk of kidney stones.
Therefore, for patients with kidney disease, it is very important to choose and control the amount of tea they drink.
A few months later, Li Ming's condition improved significantly, his urine returned to normal, and the pain in his lower back gradually disappeared. I expressed my gratitude for Xiaoming's suggestion and decided to pay more attention to the healthy management of diet and lifestyle habits in the future.
Xiaoming's story reminds us that many habits in our daily lives can have potential health impacts, and that scientific and rational diet and lifestyle management are crucial.
Understanding your body's needs and limitations, and choosing the right drinks and foods is the key to maintaining good health.
Xiaoming realizes that although tea is a common healthy drink in life, it does not mean that it can be consumed without restrictions. Excessive consumption of tea, especially strong tea, may be taxing the kidneys and increasing the risk of kidney stones and renal insufficiency.
Therefore, he advises everyone to drink tea in moderation and choose the right tea according to their physical condition.
Tea is safe and beneficial for most people, but for those with kidney insufficiency or at risk of kidney stones, special attention should be paid to the type of tea and how much to drink.
The way to drink tea healthily is to choose tea that is low in oxalic acid, and do not overdo it, and drink it in moderation to enjoy the health benefits of tea without increasing the burden on the kidneys.
Through his medical knowledge and clinical experience, Zhang Xiaoming provided Li Ming with scientific and reasonable dietary advice to help him recover his health.
This not only reflects Xiaoming's professionalism as a doctor, but also reminds each of us to pay attention to our own health in our daily lives and make scientific and reasonable dietary choices.
In the future, Xiaoming will continue to conduct in-depth research on the relationship between tea and kidney disease, and provide scientific advice and treatment options for more patients.
