সংজ্ঞা
When you have kidney failure, one or both kidneys aren’t able to work normally. The kidneys remove waste (in the form of urine) from the body. They also balance the water and electrolyte content in the blood by filtering salt and water.
Kidney failure is divided into two categories:
- Acute kidney failure—sudden loss of kidney function
- Chronic kidney failure—slow, gradual loss of kidney function
কারণসমূহ
Kidney disease causes the tiny filters in the kidneys (called nephrons) to lose their ability to filter. Damage to the nephrons may occur suddenly after an injury or poisoning. But, many kidney diseases take years or even decades to cause damage that is noticeable.
The two most commons causes of kidney disease are:
- Diabetes—high blood sugar can damage nephrons
- High blood pressure—severe high blood pressure can damage blood vessels in the kidneys
Others causes include:
- Pyelonephritis
- গ্লোমেরুলোনফ্রাইটিস
- পলিসিস্টিক কিডনি রোগ
- জন্ম ত্রুটি
- Bilateral renal artery stenosis
- বিষক্রিয়া
- Severe trauma
- Viral infections (such as, hepatitis B, hepatitis C, HIV/AIDS)
- Long-term use of medicines that contain aspirin, acetaminophen, or ibuprofen
- Abnormal build-up of substances within the kidneys (such as, amyloidosis, protein build-up)
- Toxic reaction to drugs or x-ray dyes
- Systemic diseases (such as, lupus, polyarteritis, Wegeners granulomatosis
- Conditions that severely decrease the amount of blood (such as, burns,pancreatitis, peritonitis)
- Conditions that make it difficult to urinate (such as, enlarged prostate, kidney stones, tumors)
ঝুঁকির কারণ
Risk factors that increase your chance of developing kidney failure include:
- ডায়াবেটিস
- Genetics: polycystic kidney disease, type 1 diabetes
- Race: African American
- উচ্চ্ রক্তচাপ
- Lupus or other autoimmune diseases
- Long-term use of pain medications containing aspirin or nonsteroidal anti-inflammatory drugs (NSAIDs) in high doses
- Liver failure, jaundice
- শ্বাসযন্ত্রের ব্যর্থতা
- এইচআইভি
- ক্যান্সার
- Recent open heart surgery
- Recent surgery on an abdominal aortic aneurysm
- Condition that obstructs urine flow
- Enlargement of the prostate gland
লক্ষণ
Some kidney diseases begin without any symptoms. As the disease progresses, some of the following symptoms may develop:
- Fluid retention
- Swollen and numb hands and feet, itchy skin
- Fatigue, insomnia
- Low urine output (or no urine output in severe cases), frequent urination
- Altered consciousness
- Loss of appetite, malnutrition
- Sores, bad taste in the mouth
- বমি বমি ভাব বমি
- Muscle cramps and twitches
- নিঃশ্বাসের দুর্বলতা
- উচ্চ্ রক্তচাপ
- Low temperature
- Seizures, coma
- Breath smelling like urine
- Yellowish-brownish skin tone
রোগ নির্ণয়
ডাক্তার আপনার উপসর্গ এবং চিকিৎসা ইতিহাস সম্পর্কে জিজ্ঞাসা করবেন এবং একটি শারীরিক পরীক্ষা করবেন। পরীক্ষা অন্তর্ভুক্ত হতে পারে:
রক্ত পরীক্ষা
If the kidneys are not working properly, the blood test will show:
- An increase in:
- পটাসিয়াম
- Phosphorus
- Parathyroid hormone
- Creatinine
- Blood urea nitrogen
- A decrease in serum calcium
Other Tests
- 24-hour urine protein test—to see if your body is losing protein in the urine
- Renal ultrasound—uses sound waves to study the renal system (kidneys, bladder, and ureters)
- Biopsy—to test for kidney cell functioning
চিকিৎসা
Most chronic kidney diseases are not reversible. But, there are treatments that may be used to help preserve as much kidney function as possible. In the case of acute renal failure, treatment focuses on the illness or injury that caused the problem.
সাধারণ ব্যবস্থা
- Restricting fluids
- Doing daily weight checks
- Eating a high-carbohydrate, low-protein diet
ওষুধ
Medications used in acute or chronic kidney failure may include:
- Diuretics—to flush out the kidneys, increase urine flow, and rid the body of excess sodium (such as, furosemide, mannitol)
- Blood pressure medications (such as, ACE inhibitors)
- Medicine to treat anemia (such as, epoetin alfa [Epogen, Procrit], ascorbic acid [vitamin C])
- Sodium polystyrene sulfonate or insulin in dextrose—to control high potassium levels
- Calcium acetate—to control high phosphorus levels
Talk to your doctor about other medications you are taking. These include prescribed and over-the-counter medications, as well as herbs and supplements. Since the kidneys are no longer working properly, waste can build up in your body.
ডায়ালাইসিস
Dialysis is a process that takes over for the kidneys and filters waste from the blood. This may be done on a short-term basis until kidney function improves or it may be done until you have a kidney transplant.
কিডনি প্রতিস্থাপন
This may be the right option for some patients. Having a successful transplantdepends on many factors, such as what is causing the kidney damage and your overall health.
রক্ত পরীক্ষা
Your doctor will monitor these blood levels:
- সোডিয়াম
- পটাসিয়াম
- ক্যালসিয়াম
- Phosphate
- Red blood cells
- Hematocrit
- প্লেটলেট
জীবনধারা পরিবর্তন
You can take the following steps to help your kidneys stay healthy longer:
- Have your blood pressure checked regularly. Take medication to control high blood pressure.
- If you have diabetes, control your blood sugar. Ask your doctor for help.
- Avoid the chronic use of pain medications.
- If you have chronic kidney disease, you may need to limit how much protein you eat. Talk to a dietician.
- Limit how much cholesterol and sodium you eat.
- If you have severe kidney disease, limit how much potassium you eat. If your kidneys are failing, get help from a dietician.
If you are diagnosed with kidney failure, follow your doctor’s instructions.
প্রতিরোধ
In some cases, you cannot prevent kidney failure. But, there are some steps you can take that will lower your risk:
- Maintain normal blood pressure.
- If you have diabetes, control your blood sugar.
- Avoid long-term exposure to toxic substances, such as lead and solvents.
- Do not abuse alcohol or over-the-counter pain medication.
- If you have chronic kidney failure, talk to your doctor before you become pregnant.
