Kidneys are one of the critical organs of the human body. From waste filtration to vitamin D activation, from blood pressure regulation to blood sugar regulation, the kidneys are responsible for numerous biological activities within the body.
Therefore, we need to know how to keep kidneys healthy, how to improve kidney function, and lastly, understand how prevention of kidney disease can be achieved.
Kidneys have several functions within the body, and therefore, keeping them healthy is of paramount importance. The following are the important functions of kidneys:
The internet is flooded with questions, like “How to keep kidneys healthy?”; “How to know your kidney is healthy?”; “How to maintain kidney health?”; or even “How to improve kidney function?”
In this section, we are extensively discussing the important kidney health tips that are going to help in the prevention of kidney diseases and keep the kidneys strong and healthy.
Some of the best exercises for kidney health are:
Some of the foods good for kidneys are:
Obesity and overweight increase the risk of hypertension and diabetes, which in turn increase the risk of kidney disease.
Maintaining a healthy weight through routine exercise and a kidney-friendly diet is important.
A well-planned diet for kidney patients comprises vegetables, fruits, whole grains, and low-fat dairy products.
Studies have concluded that poor sleep increases the risk of developing chronic kidney disease. People should take measures to improve sleep duration and quality, especially those at increased risk of kidney diseases.
Poor sleep directly causes renal dysfunction through sympathetic nervous system activation and indirectly through increased inflammation, resulting in glomerular injury. People should aim for at least 7 to 8 hours of sleep every night.
Smoking increases the risk of kidney diseases through several mechanisms. Firstly, it reduces the effect of blood pressure medications, resulting in poorly controlled blood pressure.
High blood pressure may cause kidney disease. Secondly, smoking reduces blood flow to the kidneys and other vital organs. In patients with kidney diseases, quitting smoking may reverse or delay the progression of kidney damage.
Smokers should consult their doctors regarding customized measures that may help them quit smoking.
People who drink alcohol in excess quantities are at twice the risk of kidney disease. This risk further increases if the person is also a smoker.
The kidneys of heavy drinkers need to function harder. Prolonged heavy drinking results in kidney dysfunction. Further, people who drink a considerable quantity of alcohol within a short period of time have dangerously high blood alcohol levels.
It causes an acute kidney injury. Therefore, it is important to drink in moderation, or better yet, quit alcohol consumption.
If not managed, prolonged stress results in several harmful effects on the body, such as a faster heart rate, increased blood pressure, and higher fat and sugar levels in the blood.
High blood pressure and high sugar levels in the blood damage the filtering units of the kidneys, resulting in kidney dysfunction. It is, therefore, important to practice stress-reducing activities.
These include getting involved in hobbies, doing yoga and meditation, sleeping well, and performing prayers.
High blood sugar levels damage the filtering units of the kidneys, resulting in diabetic nephropathy.
High blood pressure and underlying cardiovascular diseases also increase the risk of kidney problems.
It is important to manage diabetes, high blood pressure, and cardiovascular disease through medications and lifestyle modifications. Routine sugar and blood pressure checks help reduce the risk of kidney disease.
Guidelines recommend drinking optimum fluid to produce a urine volume of about 2 to 2.5 liters per day.
It helps reduce the risk of stone formation and urinary tract infections. Further, studies also indicate that drinking plenty of fluid prevents kidney damage.
Drinking enough water after taking certain medications may also reduce the risk of kidney damage.
However, patients on dialysis should consult with their healthcare provider about the volume of water to be taken during the day.
Apart from increasing blood pressure and causing gastric ulcers and bleeding, several over-the-counter medications, especially anti-inflammatory medications, have a damaging effect on the kidneys.
Those wondering how to maintain kidney health should avoid taking these medications frequently or for a prolonged period. They should consult with their healthcare providers before taking these drugs.
Certain factors increase the risk of kidney disease. These include hypertension, diabetes, obesity or overweight, heart disease, a family history of chronic kidney disease, advanced age, and inherited renal disorders.
People with one or more of these risk factors should undergo routine kidney examinations.
There are several ways to know if your kidneys are healthy. The following are some of the signs your kidneys are functioning well:
That said, some kidney diseases may not have any symptoms initially, and their symptoms become apparent as the disease advances. Therefore, it is important to consider regular health check-ups, which may involve physical examinations and imaging of kidneys.
Patients with the following symptoms should consult with nephrologists:
Kidneys are vital organs in the human body. They perform several essential functions, such as waste filtration, fluid homeostasis, blood pressure management, formation of red blood cells, detoxification, activation of vitamin D, excretion of drug metabolites, electrolytic balance, blood sugar regulation, and acid-base balance.
Several measures help maintain optimal health of the kidneys. Some of the important kidney health tips include a healthy diet, routine exercise, managing underlying medical conditions like diabetes and hypertension, quitting smoking, drinking alcohol in moderation (or avoiding alcohol), drinking plenty of fluid, and undergoing a routine renal examination.
The doctor may suggest specific foods for kidney disease. People may consult with healthcare providers about how to improve kidney function through food and exercise.
