Stage 3 Chronic Kidney Disease (CKD) is a condition in which there is moderate damage to the kidneys, resulting in decreased kidney function. In Stage 3 CKD, the glomerular filtration rate (GFR), which measures how well the kidneys are filtering waste from the blood, is between 30 and 59 milliliters per minute per 1.73 meters squared.
Cause of (stage 3ckd):
There are many potential causes of stage 3 CKD, including:
Diabetes: Diabetes is the leading cause of CKD worldwide. High blood sugar levels can damage the small blood vessels in the kidneys, leading to decreased kidney function over time.
Hypertension: High blood pressure can damage the blood vessels in the kidneys, leading to decreased kidney function.
Glomerulonephritis: This is a group of diseases that cause inflammation and damage to the glomeruli, the tiny structures in the kidneys that filter waste and excess fluids from the blood.
Polycystic kidney disease: This is an inherited condition in which cysts develop in the kidneys, causing damage and decreased function over time.
Autoimmune diseases: Certain autoimmune diseases, such as lupus, can cause inflammation and damage to the kidneys, leading to decreased function.
Obstructive uropathy: This occurs when something blocks the flow of urine out of the kidneys, causing damage and decreased function over time.
Chronic use of certain medications: Long-term use of certain medications, such as nonsteroidal anti-inflammatory drugs (NSAIDs) or some antibiotics, can cause damage to the kidneys and lead to decreased function.
Other factors: Other factors that can contribute to stage 3 CKD include a family history of kidney disease, smoking, obesity, and advanced age.
Symptom of (stage 3 CKD):
The symptoms of stage 3 CKD can include:
- Fatigue and weakness
- Fluid retention, swelling in legs, feet, or ankles
- Urine changes: Decreased urine output or dark-colored urine
- Increased need to urinate, especially at night
- High blood pressure
- Anemia (low red blood cell count)
- Loss of appetite or nausea
- Metallic taste in the mouth or bad breath
- Itching or dry skin
- Bone pain or fractures due to weakened bones (osteoporosis)
- Decreased sexual interest and erectile dysfunction
- Difficulty concentrating, memory loss or confusion
- Shortness of breath, especially during physical exertion.
It's important to note that some people with stage 3 CKD may not experience any symptoms, and the condition may be diagnosed through routine blood and urine tests. If you experience any of the above symptoms or have risk factors for CKD, such as diabetes, high blood pressure, or a family history of kidney disease, it's important to speak with your healthcare provider.
Diet for (stage 3 CKD ):
A person with stage 3 chronic kidney disease (CKD) may need to make changes to their diet to help manage their condition. Here are some general dietary guidelines for people with stage 3 CKD:
Limit protein intake: Too much protein can be hard on the kidneys, so it's important to limit protein intake to about 0.8 grams of protein per kilogram of body weight per day. This means that a person who weighs 70 kg (154 pounds) should aim for about 56 grams of protein per day.
Reduce sodium intake: Sodium can increase blood pressure and cause fluid retention, which can put a strain on the kidneys. Aim for less than 2,300 mg of sodium per day.
Control potassium and phosphorus intake: The kidneys are responsible for regulating potassium and phosphorus levels in the body, so people with CKD may need to limit these nutrients in their diet. Foods that are high in potassium include bananas, oranges, tomatoes, spinach, and beans, while high-phosphorus foods include dairy products, meat, fish, and whole grains.
Increase intake of fruits and vegetables: Fruits and vegetables are high in nutrients and antioxidants that can help protect the kidneys and reduce the risk of heart disease. However, be careful to choose low-potassium options.
Choose healthy fats: Unsaturated fats found in olive oil, avocado, nuts, and seeds are healthy and may help protect the kidneys.
Stay hydrated: Drinking enough water is important for kidney function, but people with CKD may need to limit their fluid intake if they have symptoms of fluid overload.
Work with a registered dietitian: A registered dietitian can help develop a personalized diet plan that takes into account an individual's specific needs and preferences. They can also provide guidance on portion sizes, meal planning, and cooking techniques.
It's important to note that these guidelines are general and may need to be modified based on an individual's specific health status and medical history. Always consult with a healthcare provider before making any significant dietary changes.
Risk factor of (stage 3 CKD):
Here are some risk factors associated with stage 3 CKD:
Diabetes: Uncontrolled diabetes is a leading cause of CKD. It can cause damage to blood vessels and nerves in the kidneys, leading to reduced kidney function.
High blood pressure: High blood pressure can damage blood vessels in the kidneys, reducing their ability to function properly.
Smoking: Smoking can damage blood vessels throughout the body, including those in the kidneys. It can also worsen existing kidney damage.
Obesity: Obesity is a risk factor for CKD, as it can lead to diabetes and high blood pressure, both of which can damage the kidneys.
Family history of kidney disease: A family history of kidney disease increases the risk of developing CKD.
Age: As we age, our kidneys naturally lose some function. This can increase the risk of developing CKD.
Race: Some racial and ethnic groups are at a higher risk of developing CKD, including African Americans, Native Americans, and Hispanic Americans.
Certain medications: Some medications can cause kidney damage, especially if taken in high doses or over a long period of time.
Other medical conditions: CKD can be a complication of other medical conditions, such as lupus, polycystic kidney disease, and glomerulonephritis.
It is important to manage these risk factors to reduce the risk of developing CKD or slow its progression if already diagnosed.
Treatment:
Management of Stage 3 CKD typically involves treating underlying conditions such as diabetes or high blood pressure, adopting a healthy lifestyle such as a balanced diet, regular exercise, and avoiding smoking, and monitoring kidney function regularly. In some cases, medications may be prescribed to manage specific symptoms or complications associated with Stage 3 CKD.
