The Role Of The Kidneys
The kidneys are two bean-shaped organs located in your lower back, just below your ribcage. Their main function is to filter waste products and excess fluids from your blood, which are then excreted in the form of urine.
The basic functioning of the kidneys involves three main processes: filtration, reabsorption, and secretion.
Filtration: Your kidneys filter your blood by removing waste products and excess fluids. Blood flows into your kidneys through small blood vessels called capillaries, which are surrounded by tiny filters called nephrons. The nephrons filter the blood, removing waste products and excess fluids, and send the filtered blood back into circulation.
Reabsorption: As the filtered blood passes through the nephrons, important nutrients and fluids are reabsorbed back into your bloodstream. This helps your body maintain the proper balance of fluids and nutrients.
Secretion: In addition to filtering and reabsorbing, your kidneys also secrete hormones and other substances that help regulate blood pressure, stimulate the production of red blood cells, and maintain the proper balance of minerals and electrolytes in your body.
What Is CKD And How Can I Support My Kidneys
CKD stands for Chronic Kidney Disease, which is a condition in which your kidneys gradually lose function over time, usually over a period of months or years. This can lead to a build-up of waste products and fluids in your body, which can cause a range of symptoms and complications.
There are a number of things you can do to support your kidneys if you have CKD:
- Manage your blood pressure: High blood pressure is a leading cause of CKD, so it’s important to keep your blood pressure under control. This can involve making lifestyle changes like eating a healthy diet, getting regular exercise, and avoiding smoking and excessive alcohol consumption.
- Manage your blood sugar: If you have diabetes, it’s important to keep your blood sugar levels under control. High blood sugar can damage your kidneys over time.
- Stay hydrated: Drinking enough water can help your kidneys function properly by flushing waste products out of your body. However, if you have CKD, your doctor may recommend limiting your fluid intake, as your kidneys may have difficulty filtering excess fluids.
- Eat a healthy diet: Eating a diet that is low in sodium, phosphorus, and protein can help reduce the workload on your kidneys. Your doctor or a registered dietitian can help you create a kidney-friendly meal plan.
- Take your medications as prescribed: If you have CKD, your doctor may prescribe medications to help manage your symptoms and slow the progression of the disease. It’s important to take these medications as directed and to let your doctor know if you experience any side effects.
- Get regular kidney function tests: If you have CKD, your doctor will likely recommend regular blood and urine tests to monitor your kidney function. This can help detect any changes in your kidney function early so that treatment can be started before your kidneys are severely damaged.
Are Kidneys Like Filters In A Car?
When we compare the kidneys to the filters in a vehicle, you will find some similarities in how they work, but there are also some key differences.
Both the kidneys and filters in a vehicle are designed to remove waste and impurities from a fluid. In a vehicle, the filters are typically used to remove contaminants from the engine oil, fuel, or air, while the kidneys filter waste products from the blood. In both cases, the filtration process involves passing the fluid through a physical filter that traps unwanted particles and impurities. In the kidneys, the filtering takes place in tiny structures called nephrons, which are like microscopic filters that remove waste products and excess fluids from the blood.
However, there are also some important differences between the kidneys and filters in a vehicle. For example:
Complexity:
The kidneys are much more complex than a simple filter in a vehicle. The kidneys are organs that are made up of many different types of cells and structures, all working together to filter the blood and maintain the proper balance of fluids and nutrients in the body. Filters in a vehicle are typically much simpler in design and function.
Maintenance:
While filters in a vehicle need to be replaced periodically to ensure they continue to function properly, the kidneys are self-maintaining and do not require regular replacement. However, the kidneys can be damaged or impaired by certain diseases or conditions, which can require medical intervention.
What Hormones Or Enzymes Do The Kidneys Need To Work Well?
The kidneys rely on a variety of hormones and enzymes to function properly. Here are some examples:
Renin: Renin is an enzyme that is produced and secreted by cells in the kidneys. It plays a key role in regulating blood pressure by converting angiotensinogen, a protein produced by the liver, into angiotensin I, which is then converted to angiotensin II by other enzymes. Angiotensin II causes blood vessels to narrow, which helps to raise blood pressure.
Erythropoietin: Erythropoietin is a hormone produced by cells in the kidneys in response to low levels of oxygen in the blood. It stimulates the bone marrow to produce more red blood cells, which carry oxygen to the body’s tissues.
Calcitriol: Calcitriol is a hormone that is produced by cells in the kidneys in response to low levels of calcium in the blood. It helps to regulate the levels of calcium and phosphorus in the body, and is important for bone health.
Prostaglandins: Prostaglandins are a group of hormones that are produced by cells throughout the body, including the kidneys. They play a role in regulating blood flow to the kidneys and maintaining the proper balance of fluids and electrolytes in the body.
Dopamine: Dopamine is a neurotransmitter that also acts as a hormone. It is produced by cells in the kidneys and plays a role in regulating blood pressure and blood flow to the kidneys.
Overall, the proper functioning of the kidneys depends on a complex interplay of hormones, enzymes, and other signalling molecules, all working together to maintain the body’s internal environment.
Tell Me About Renin. Where Does It Come From And Where Does It Go, And Work In The Body?
Renin is an enzyme that is produced and secreted by specialized cells in the kidneys called juxtaglomerular cells. Renin is released in response to various signals, including low blood pressure, low blood volume, or low sodium levels in the blood.
Once released, renin acts on a protein called angiotensinogen, which is produced by the liver and released into the bloodstream. Renin cleaves angiotensinogen into a shorter peptide called angiotensin I, which is then converted to angiotensin II by another enzyme called angiotensin converting enzyme (ACE).
Angiotensin II is a potent vasoconstrictor, meaning it causes blood vessels to narrow, which increases blood pressure. It also stimulates the release of aldosterone from the adrenal glands, which increases the reabsorption of sodium and water by the kidneys, further increasing blood volume and blood pressure.
The renin-angiotensin-aldosterone system (RAAS) is a complex system that helps to regulate blood pressure and blood volume. Renin plays a key role in this system by initiating the conversion of angiotensinogen to angiotensin I, which ultimately leads to the production of angiotensin II and the activation of various downstream signalling pathways.
Renin is also involved in other physiological processes in the body, such as the regulation of electrolyte balance and the production of erythropoietin, a hormone that stimulates the production of red blood cells.
Overall, renin is a key enzyme in the body that plays a critical role in the regulation of blood pressure, blood volume, and other important physiological processes. Dysfunction of the renin-angiotensin system can lead to a variety of conditions, including hypertension, heart failure, and kidney disease.
How Can I Assure That I Have Enough Renin In My Body?
There is no direct way to measure the level of renin in the body, as it is an enzyme that is primarily produced and regulated within the kidneys. However, there are several steps you can take to support the proper functioning of the renin-angiotensin system and promote healthy levels of renin in the body:
Maintain a healthy blood pressure: High blood pressure can disrupt the proper functioning of the renin-angiotensin system and lead to overproduction of renin. To maintain healthy blood pressure, it’s important to eat a balanced diet, exercise regularly, manage stress, and avoid smoking and excessive alcohol consumption.
Stay hydrated: Dehydration can lead to low blood volume and trigger the release of renin. To prevent dehydration, aim to drink plenty of water and other fluids throughout the day, especially during hot weather or when engaging in physical activity.
Follow a low-sodium diet: Excessive sodium intake can disrupt the balance of electrolytes in the body and trigger the release of renin. To reduce your sodium intake, avoid processed and packaged foods, limit your consumption of table salt, and focus on whole, fresh foods.
Manage underlying medical conditions: Certain medical conditions, such as diabetes, kidney disease, and heart disease, can disrupt the proper functioning of the renin-angiotensin system and lead to imbalances in renin levels. It’s important to work closely with your pHLife consultant to manage any underlying health conditions and monitor your blood pressure and kidney function regularly.
By taking these steps, you can help to support the proper functioning of the renin-angiotensin system and promote healthy levels of renin in the body. However, it’s important to keep in mind that renin levels can vary depending on individual factors and physiological conditions, and there is no guaranteed way to ensure a specific level of renin in the body.
How Does The Renin-Angiotensin System Work?
The renin-angiotensin system (RAS) is a complex hormonal system that plays a crucial role in the regulation of blood pressure, electrolyte balance, and fluid homeostasis in the body. The system involves several steps, starting with the release of renin from specialized cells in the kidneys, and culminating in the activation of angiotensin II, a potent vasoconstrictor that helps to increase blood pressure.
- Release of renin: The renin-angiotensin system is triggered by a decrease in blood pressure or volume, which is sensed by specialized cells in the kidneys called juxtaglomerular cells. These cells respond by secreting the enzyme renin into the bloodstream.
- Activation of angiotensinogen: Renin acts on a protein called angiotensinogen, which is produced by the liver and released into the bloodstream. Renin cleaves angiotensinogen to produce a shorter peptide called angiotensin I.
- Conversion of angiotensin I to angiotensin II: Angiotensin I is converted to angiotensin II by the action of the enzyme angiotensin-converting enzyme (ACE), which is primarily found in the lungs.
- Effects of angiotensin II: Angiotensin II has several effects on the body, including:
- Vasoconstriction: Angiotensin II causes the blood vessels to narrow, which increases blood pressure and promotes blood flow to vital organs.
- Aldosterone release: Angiotensin II stimulates the release of aldosterone from the adrenal glands, which promotes the reabsorption of sodium and water in the kidneys, further increasing blood volume and blood pressure.
- Antidiuretic hormone release: Angiotensin II also stimulates the release of antidiuretic hormone (ADH) from the pituitary gland, which promotes the reabsorption of water in the kidneys and helps to maintain fluid balance in the body.
- Stimulation of thirst: Angiotensin II also stimulates the thirst center in the brain, leading to an increased desire to drink fluids.
- Negative feedback: Once blood pressure and blood volume return to normal levels, the renin-angiotensin system is suppressed through negative feedback mechanisms. Specifically, angiotensin II acts on cells in the kidneys to inhibit the release of renin and promote the excretion of sodium and water in the urine, which helps to lower blood pressure and volume.
The renin-angiotensin system is a complex hormonal system that helps to regulate blood pressure, fluid balance, and electrolyte homeostasis in the body. Dysfunction of the system can lead to a variety of health problems, including hypertension, heart failure, and kidney disease.
What Can I Do To Improve RAS
The renin-angiotensin system (RAS) is a complex physiological system that plays an important role in regulating blood pressure and fluid balance in the body. While there is no guaranteed way to “improve” the RAS, there are several steps you can take to support the proper functioning of the system and maintain healthy blood pressure and fluid balance:
Maintain a healthy lifestyle: Eating a balanced diet, exercising regularly, managing stress, getting enough sleep, and avoiding smoking and excessive alcohol consumption can all help to support healthy blood pressure and proper RAS function.
Manage underlying health conditions: Certain medical conditions, such as hypertension, diabetes, and kidney disease, can disrupt the proper functioning of the RAS and lead to imbalances in blood pressure and fluid balance. Working closely with your pHLife consultant to manage these conditions and monitor your blood pressure and kidney function can help to maintain healthy RAS function.
Follow a low-sodium diet: Excessive sodium intake can disrupt the balance of electrolytes in the body and trigger the release of renin, leading to imbalances in blood pressure and fluid balance. To reduce your sodium intake, avoid processed and packaged foods, limit your consumption of table salt, and focus on whole, fresh foods.
Keep in mind that the RAS is a complex system that is regulated by many factors, and maintaining healthy RAS function may require a combination of lifestyle changes, medical interventions, and ongoing monitoring and management.
Will Alcohol And Smoking Impact On My Kidneys?
Both alcohol and smoking can have negative impacts on your kidneys.
Alcohol is a diuretic, which means it increases urine production and can lead to dehydration. This can put additional stress on the kidneys, which are responsible for filtering waste and excess fluid from the body. Over time, excessive alcohol consumption can lead to inflammation and damage to the kidneys, and increase the risk of kidney disease.
Smoking, on the other hand, can lead to reduced blood flow to the kidneys and impair their ability to filter waste and maintain proper fluid balance in the body. Smoking can also increase the risk of developing high blood pressure and diabetes, both of which can further damage the kidneys.
In addition to these direct impacts, both alcohol and smoking can contribute to other health conditions that can negatively impact the kidneys, such as cardiovascular disease and liver disease.
Therefore, it’s important to limit alcohol consumption and quit smoking to support the health of your kidneys and overall health. If you are struggling with alcohol or tobacco addiction, talk to your pH4life consultant for support and resources to help you quit.
What Foods Should I Avoid To Avoid Damaging Or Over Stimulating The Kidneys And What Foods Could Be Good For My Kidneys
To support the health of your kidneys, it’s important to eat a balanced and varied diet that includes a variety of nutrient-rich foods. In general, it’s best to avoid processed and high-sodium foods, as well as foods that are high in sugar and unhealthy fats, which can contribute to inflammation and damage to the kidneys.
Here are some specific foods to limit or avoid to avoid damaging or over-stimulating the kidneys:
Processed and packaged foods: These often contain high amounts of sodium and preservatives that can put stress on the kidneys and lead to fluid retention.
Sugary drinks and snacks: These can contribute to inflammation and oxidative stress in the body, which can damage the kidneys over time.
Red meat and processed meats: These are high in saturated fat and can contribute to inflammation and damage to the kidneys.
Alcohol: As mentioned earlier, alcohol can put stress on the kidneys and contribute to inflammation and damage over time.
Try to include these foods in your diet, to assist in promoting kidney health:
Green vegetables: These are rich in antioxidants and anti-inflammatory compounds that can help to support kidney health.
Whole (Low GI) grains: These are a good source of fiber and other nutrients that can help to support overall health and reduce the risk of kidney disease.
Lean protein sources: These can include fish or chicken which are good sources of protein.
Healthy fats: Omega-3 fatty acids found in foods like salmon, walnuts, and chia seeds can help to reduce inflammation and support overall kidney health.
Water: Staying hydrated with water is important for kidney health, as it helps to flush out toxins and waste products from the body.
It’s important to note that the specific dietary recommendations for kidney health may vary depending on individual health conditions and medical history. If you have concerns about your kidney health, it’s best to talk to your pH4Health consultant for personalized recommendations.
What Are Kidney Stones, How Are They Formed And Who Gets These?
Kidney stones are hard, mineral-based deposits that form inside the kidneys and can cause pain and discomfort when they pass through the urinary tract. They can range in size from tiny grains to larger stones that can be several centimetres in diameter.
Kidney stones are formed when certain minerals and other substances in the urine, such as calcium, oxalate, and uric acid, become concentrated and crystallize. These crystals can then clump together and form stones. The exact cause of kidney stone formation is not always clear, but risk factors may include:
- Dehydration: When the body doesn’t have enough water, urine becomes more concentrated and can increase the risk of stone formation.
- Diet: Eating a diet high in salt, animal protein, and oxalate-containing foods (such as spinach and chocolate) can increase the risk of stone formation.
- Family history: Kidney stones may run in families, suggesting a genetic component.
- Certain medical conditions: Conditions that affect the kidneys, urinary tract, or other organs (such as gout or inflammatory bowel disease) can increase the risk of stone formation.
- Certain medications: Some medications, such as diuretics or calcium-based antacids, may increase the risk of stone formation.
Kidney stones can affect anyone, but some people may be at higher risk than others. Men are more likely to develop kidney stones than women, and the risk increases with age.
Other risk factors may include a personal or family history of kidney stones, certain medical conditions, and lifestyle factors such as dehydration and a diet high in salt and animal protein.
If you experience symptoms it’s important to see your pH4Life consultant immediately. The symptoms of kidney stones can vary depending on the size and location of the stone, but some common signs and symptoms may include:
- Severe pain in the side or back, often radiating to the lower abdomen and groin
- Painful or burning sensation when urinating
- Cloudy or foul-smelling urine
- Blood in the urine
- Nausea and vomiting
- Frequent urge to urinate
- Difficulty passing urine or a decreased urine output
Your consultant at pH4Life may perform tests, such as urine tests or imaging studies, to help diagnose kidney stones and determine the appropriate treatment.
What Problems Can I Expect If My Child Is Born With Only One Kidney?
Most people are born with two kidneys, but it is possible to be born with just one kidney. This is called renal agenesis or unilateral renal agenesis.
In many cases, people with one kidney can live healthy, normal lives with no complications. However, having only one kidney may increase the risk of certain health problems, including:
- High blood pressure: The kidneys play a key role in regulating blood pressure, and having just one kidney may make it more difficult for the body to maintain normal blood pressure levels.
- Proteinuria: Proteinuria is a condition in which there is excess protein in the urine. People with one kidney may be at higher risk of developing proteinuria, which can be a sign of kidney damage.
- Kidney disease: People with one kidney are at higher risk of developing kidney disease or other kidney-related problems.
- Kidney injury: If the remaining kidney is injured, there is no backup kidney to take over its function. This can be a concern for people who participate in contact sports or other activities that increase the risk of kidney injury.
- Pregnancy complications: Women with one kidney may be at higher risk of developing certain complications during pregnancy, including high blood pressure, preeclampsia, and gestational diabetes.
If your child is born with only one kidney, it’s important to monitor their kidney function and blood pressure regularly and to work closely with their pHLife consultant to manage any potential health risks. In most cases, people with one kidney can live healthy, normal lives with proper monitoring and care.
What Is Proteinuria And How Can It Be Avoided And Treated?
Proteinuria is a condition in which there is an abnormally high amount of protein in the urine. Normally, only small amounts of protein are present in the urine, but in cases of proteinuria, larger amounts may be excreted.
Proteinuria can be a sign of underlying kidney disease or damage, as the kidneys play a key role in filtering waste products and excess fluids from the blood, including protein. Other conditions, such as high blood pressure and diabetes, can also contribute to proteinuria.
To prevent proteinuria, it’s important to maintain a healthy lifestyle that includes regular exercise, a balanced diet, and avoiding smoking and excessive alcohol consumption. If you have underlying health conditions, such as diabetes or high blood pressure, it’s important to work with your pHLife consultant to manage these conditions and prevent further damage to the kidneys.
The treatment for proteinuria depends on the underlying cause. In some cases, lifestyle changes and medications can be used to manage underlying health conditions and reduce proteinuria. In more severe cases, additional treatments may be needed to manage kidney damage and prevent further complications. It’s important to work closely with your pH4Life consultant to determine the best course of treatment for your individual needs.
What can be the causes of Proteinuria?
Proteinuria is typically a sign of kidney disease or damage, as the kidneys play a key role in filtering waste products and excess fluids from the blood, including protein. However, proteinuria can also be a symptom of other conditions or diseases, including:
- Heart failure: In some cases, heart failure can lead to increased pressure in the blood vessels of the kidneys, which can result in proteinuria.
- Infections: Certain infections, such as urinary tract infections or kidney infections, can cause proteinuria.
- Multiple myeloma: This is a type of cancer that can cause the production of abnormal proteins, which can then be excreted in the urine.
- Rheumatoid arthritis: This is an autoimmune disorder that can cause inflammation in the kidneys, leading to proteinuria.
- Lupus: This is another autoimmune disorder that can cause inflammation in the kidneys, leading to proteinuria.
- Preeclampsia: This is a complication of pregnancy that can cause high blood pressure and proteinuria.
What Is Hypercalciuria, What Are The Symptoms And The Causes And How Can It Be Treated Naturally?
Hypercalciuria is a condition characterized by abnormally high levels of calcium in the urine. This can be caused by a variety of factors, including genetics, diet, and medical conditions.
Symptoms of hypercalciuria may include frequent urination, painful urination, and the passage of small kidney stones. However, in many cases, there are no symptoms.
Causes of hypercalciuria can include:
- Inherited factors: Some people are born with a genetic predisposition to hypercalciuria.
- Diet: Eating a diet that is high in salt, animal protein, and/or oxalate can increase the risk of hypercalciuria.
- Medical conditions: Certain medical conditions, such as hyperparathyroidism, sarcoidosis, and certain types of cancer, can cause hypercalciuria.
- Medications: Certain medications, including diuretics, antacids containing calcium, and calcium supplements, can contribute to hypercalciuria.
Treatment for hypercalciuria depends on the underlying cause. In some cases, lifestyle modifications, such as increasing water intake, reducing salt and animal protein intake, and increasing physical activity, may be effective in reducing calcium levels in the urine.
It’s important to talk to your pH4Life consultant if you suspect that you have hypercalciuria or have a history of kidney stones or other kidney-related issues. They can help determine the underlying cause and recommend appropriate treatment options. Additionally, it’s important to follow a healthy diet and lifestyle to promote overall kidney health.
What Is Hypercalcemia What Are The Symptoms And The Causes And How Can It Be Treated Naturally?
Hypercalcemia is a condition in which the level of calcium in the blood is higher than normal. The normal range for calcium in the blood is 8.5 to 10.2 milligrams per deciliter (mg/dL).
Symptoms of hypercalcemia can vary depending on the severity and the underlying cause, but may include:
- Excessive thirst and frequent urination
- Fatigue and weakness
- Nausea, vomiting, and abdominal pain
- Constipation
- Confusion or impaired thinking
- Muscle weakness and bone pain
- Kidney stones
Hypercalcemia can be caused by a variety of factors, including:
- Overactive parathyroid gland (hyperparathyroidism)
- Cancer, particularly bone cancer or cancer that has spread to the bones
- Certain medications, such as thiazide diuretics, lithium, and some antacids containing calcium
- Immobilization, which can cause calcium to be released from bones
- Vitamin D toxicity
Treatment for hypercalcemia depends on the underlying cause and the severity of symptoms. In some cases, lifestyle modifications, such as increasing fluid intake and avoiding calcium-rich foods and supplements, may be recommended. In more severe cases, medications may be prescribed, such as bisphosphonates to help prevent bone breakdown, calcitonin to reduce calcium levels, and corticosteroids to reduce inflammation. Surgery may also be necessary in some cases, such as when hyperparathyroidism is the underlying cause.
It’s important to talk to your pH4Life consultant if you suspect that you have hypercalcemia or have a history of kidney stones or other kidney-related issues. They can help determine the underlying cause and recommend appropriate treatment options. Additionally, it’s important to follow a healthy diet and lifestyle to promote overall kidney health.
