What is CKD and what are its causes?
CKD also known as Chronic Kidney disease is when there is subtle or complete dysfunction in
your kidney, in serious cases, where CKD has grown a lot, it also causes kidney failure. CKD
develops in a time of 3 months minimum. Our kidney’s job is to regulate the blood, remove
waste, keep the electrolytes steady and stable and produce hormones. Our kidney filters our
blood daily, in detail, filters 120-100 ml per minute per 1.73m^3 of our body. This differs as it is
stated that this amount is lower in women than in men, and as our body grows older, the amount
filtered is slowly decreasing. The filtration process of our kidneys is known as Glomerular
filtration, and its rate mentioned as 120 - 100 ml per minute*. Now, there are many causes of
CKD, one being Hypertension, hypertension is a cycle, it is when, there is less fluid delivered to
the kidney to filter, this causes the kidney to spread a distress signal, which makes it release
renin, which is a hormone which instructs the body to increase the blood pressure more than
needed, and this increased blood pressure causes hypertension, this reason states as why we
should drink more water and fluids throughout the day. Now, Hypertension causes the renal
artery to widen, which makes the lumen narrow, this is the reason less fluid is delivered to the
kidney, due to this low amount of fluid that is received, this resulting in the kidney to have an
ischemic injury to the glomerulus, which filter the fluid within the kidney, due to this injury, Foam
like cells called macrophages tend and very likely slip into the injured glomerulus, these
macrophages secrete the growth of TGF, TGF is an important function which helps in recovering
from injury, releasing anti-inflammatory functions in to the body, this function causes the
mesangial cells to regress or turn into a more devolve and immature state of itself known as
mesoangioblasts. These mesoangioblasts start to secrete extracellular matrix, extracellular
matrix is when a network of an array of macromolecules is formed around our body, specifically
here, in our kidney, extracellular matrix is extra tissue around our glomerulosclerosis, which is
the element in the kidney that filters all the fluids, to harden, which diminishes the nephron’s
ability to release the filtered fluid, and this causes chronic kidney disease, There are many more
causes to CKD such as Lupus, Rheumatoid arthritis, HIV, NSAIDS, And toxins within tobacco. A
normal kidney Filters Urea, which is normally present in our urine filtered, this is when we have
a healthy glomeruli, but on the other hand, if one has CKD, because of hardening of our
glomerulosclerosis, the urea is not properly filtered, leading the left our urea into the blood,
which causes azotemia, this disease causes body ache and nausea, and if not treated, it
becomes the reason of going into a coma or even death. Same as Urea, our kidney is also
responsible for keeping our electrolytes balanced, this includes potassium levels to be stable
and managed, a kidney without CKD properly filtered the extracted potassium in our urine, but a
kidney with CKD forces the unfiltered potassium enter our blood, causing hyperkalemia, which
is a reason of cardiac arrest, less fluid consumed causes hypertension, which causes CKD and
if not treated results in fatal situations, and this explains why we should consume fluids like
water or few juices that help our kidney to filter us properly, now this relates to osmosis in our
body which is further mentioned.
How does osmosis help with CKD
Osmosis is the process in which water is the process when water molecules go through
a semipermeable membrane from a highly concentrated area to a low concentrated
area. Now the process of osmosis helps our kidneys and is a very important process for
one’s human body, now because of osmosis, blood is refined and purified as much as it
can by the process of osmosis. The water in our blood is refined not entirely but,
partially filters the blood, this making sure that no blood is passed and thrown out
through urine, in many cases the blood is not able to be refined and as because of that
it is present in urine, in cancer patients, this happens frequently as their kidneys done
work to their full potential, osmosis helps filtering water in blood in the kidney in simple
words, and is very helpful for patients who have their kidneys in a bad state, in simple
words, osmosis helps water to be filtered from one’s blood and prevent it to be
transferred into one’s urine
Stages of CKD
There are a total of 5 stages of Chronic Kidney disease, as time passes, CKD and one’s
kidney starts to worsen, and if not treated properly then it worsens very quickly, that's
why precautions, medications and consultancy must be taken by a kidney specialist. In
stages 1-3 one’s kidney is still able to function appropriately and filter out waste from
our blood. But in stages 4-5 it is very hard for the kidney to filter anything making it
nearly impossible to filter one’s blood, and in these stages (4-5) we must keep our
kidney in use and as healthy as possible. Here are the 5 Stages:
Stage 1 - In stage one, our kidney is mostly functional, and works fine, knowing that
CKD has been identified, yet there is still mild damage to one’s kidney, it cannot be
identified as there is damage to the kidney, physically seen or signs of damage, Stage
one is intended to state that your filtration rate is normal, thought protein is present in
your urine, which is a direct indication that one has CKD Stage 1, The eGFR result
should be 90 or higher (>=90). Doctors check one’s body for CKD by taking an eGFR
test (A blood test, where the blood is specifically examined for kidney damage
identification), Blood pressure test, and urine test. Natural Symptoms of CKD stage 1
are high blood pressure, Swelling in feet or hands, kidney damage seen in CT scans
(etc.), protein or blood in urine.
Stage 2 - Stage two is just slightly worse than stage 1, one’s kidney will still function and
filter right to appropriate amounts of one’s blood, Yet, there is still slightly more damage
seen and difficulties. Doctors identify Stage 2 by, CT scans, blood test or eGFR and
blood pressure tests. The eGFR result should be 60 - 89. In stage 2 of CKD, one’s
kidney works slightly worse than stage one 1, difficulties start to occur slowly and
damage can be seen, in this stage of CKD might be irreversible, natural symptoms such
as swelling in hands or feet, visible kidney damage, protein or blood in urine.
Stage 3:
Stage 3a : Stage 3a is when your kidney starts to get more damaged, filters one’s
blood, but, struggles doing so, unfiltered waste can build up and start harming one’s
body as well, this build up can cause high blood pressure, anemia and bone defects
and problems. Stage 3 is the middle, it is stated that CKD after one’s kidneys have
reached stage 3 is irreversible and can only be controlled by following instructions by
your doctor, this stage does not fully shut down one’s kidneys, they still work and there
is yet no need of a kidney transplant or dialysis. Doctors check for this by blood
pressure test, eGFR (blood test specifically to obtain information regarding one’s
kidney) the eGFR test for stage 3a is (45-59), Kidney biopsy, and this can also be
passed genetically from your parents or your family tree (preferably if one’s family
member (Father or Mother) had it). There are more symptoms present now, a few new
ones being: feeling weak or tired, skin turning dry or itchy, muscle cramp, sleep
deprivation or any sleeping problems, restless leg syndrome, more or less urination and
urine is more dark and more concentrated than usual. Stage 3a is mostly irreversible
and cannot be cured, it can only be monitored and controlled. Both stages 3a and 3b
are the same but stage 3b has a lower eGFR rate.
Stage 3b: Stage 3b is when your kidney starts to get more damaged, filters one’s blood,
but, struggles doing so, unfiltered waste can build up and start harming one’s body as
well, this build up can cause high blood pressure, anemia and bone defects and
problems. Stage 3 is the middle, it is stated that CKD after one’s kidneys have reached
stage 3 is irreversible and can only be controlled by following instructions by your
doctor, this stage does not fully shut down one’s kidneys, they still work and there is yet
no need of a kidney transplant or dialysis. Doctors check for this by blood pressure test,
eGFR (blood test specifically to obtain information regarding one’s kidney) the eGFR
test for stage 3a is (30-44), Kidney biopsy, and this can also be passed genetically from
your parents or your family tree (preferably if one’s family member (Father or Mother)
had it). There are more symptoms present now, a few new ones being: feeling weak or
tired, skin turning dry or itchy, muscle cramp, sleep deprivation or any sleeping
problems, restless leg syndrome, more or less urination and urine is more dark and
more concentrated than usual. Stage 3a is mostly irreversible and cannot be cured, it
can only be monitored and controlled. Both stages 3a and 3b are the same but stage 3b
has a lower eGFR rate.
Stage 4: Stage 4 is the last stage before kidney failure, so it is very important to keep
precautions and take care of our kidney appropriately, as Stage 4 forms, health
problems also start to occur throughout one’s body, problems such as: heart disease,
anemia, high blood pressure, high phosphorus and potassium, metabolic acidosis and
bone disease. New natural symptoms also kick in, such as: loss of appetite, pain in
one’s lower back, feeling heavy nausea and headaches and feeling sick making one
vomit, this stage can be tested by eGFR reports and urine test. One’s eGFR result is to
be 15-29 to be diagnosed as stage 4 CKD. one’s consultant or doctor is to decide if one
needs a kidney transplant or dialysis, if one’s kidney is close to stage 5 or significantly
failing, the doctor will inform one, if a kidney transplant is to be taken place, or dialysis,
there is no going back now and the only option is to properly maintain our kidneys.
Stage 5: stage 5 is the final stage, either one’s kidney is at the brim of failing or it has
already failed, There is no cure and it is impossible to be reversed, same health
problems but more serious this stage, stage 5 can only be tested by eGFR or urine
tests, your eGFR is to be <15 or less than 15 to be diagnosed, after reaching stage 5, it
is necessary to have a kidney transplant or dialysis. New natural symptoms like; no or
very less urine, breathing issues and change in skin color start to occur. It is again
important to start dialysis or have a kidney transplant.
Symptoms of CKD
Chronic kidney disease should mostly be confirmed by a urine test or an eGFR test,
though, we should all be aware of natural symptoms or alerts that one’s body receives.
Some of the few symptoms that are found are:
● Itchy and dry skin
● Muscle cramps
● Frequent vomiting and stomach ache
● Loss of appetite
● Swelling in hands, feet, ankles or leg
● Less urination
● Breathing issues
● Sleep deprivation and other sleeping issues
● Pain in lower back
● High Blood pressure
●
These symptoms do not always start to come through from stage 1, many people have
experienced these symptoms from the start of stage 3, the best way is to get tested for
CKD and be on a safer side.
causes of CKD
Diabetes: Diabetes also is a cause for CKD in one’s body, as Diabetes is when your
blood sugar is high, unmanaged and not monitored for a while, and the rising high sugar
level can slowly and unknowing damage many organs in one’s body, which also
includes affecting the kidney and slowing its functionality. To be exact, diabetes affects
your kidney and does not allow them to filter our blood properly. It damages the blood
vessels, and it also takes the nephron’s ability and makes it difficult for the kidney to
function in a healthy state. (Type 1 and type 2 diabetes)
Hypertension
Hypertension is a cycle, it starts with something we all do sometimes, not consuming
enough fluid such as water, this causes a hormone called renin to be released and give
a distress signal throughout the body, this signal causes the blood pressure to increase
in our body, and if this happens regularly and is not maintained properly, this could
result in hypertension, and this takes our kidneys ability to function and filter properly,
our kidneys part is to keep control of the electrolytes in our body, keep them steady,
potassium plays an important role in that, because of our kidney is not being able to
filter any substance properly, potassium that should have been excreted through urine is
now transferred in our blood, this causes hyperkalemia, which in many cases causes
cardiac arrest, resulting to death.
Interstitial nephritis
Interstitial nephritis is when our kidney is surrounded by an extracellular matrix, a
substance which not only takes away the ability of filtering gradually, but also damages
the inside of our kidneys, scarring and hardening them, and so, blood is not filtered
properly.
Glomerulonephritis
Glomerulonephritis is when one’s kidney is inflamed and is not able to filter properly, it is
an inflammation in the glomeruli which makes the glomeruli very hard to filter our blood,
and as this increases, the kidney is no longer in a state where it can filter any blood.
Things that increase your CKD
● Diabetes
● High blood pressure
● Heart (cardiovascular) disease
● Smoking
● Obesity
● Family history of kidney disease
● Abnormal kidney structure
● Older age
● Frequent use of medications that can damage the kidneys
Complaints
● Fluid retention, which could lead to swelling in your arms and legs
● A sudden rise in potassium levels in your blood (hyperkalemia), which could
impair your heart's function and can be life-threatening
● Anemia
● Heart disease
● Weak bones and an increased risk of bone fractures
● Damage to your central nervous system, which can cause difficulty
concentrating, personality changes or seizures
● Decreased immune response, which makes you more vulnerable to infection
● Pericarditis, an inflammation of the saclike membrane that envelops your heart
Ways to help reduce the risk of CKD (increase in stages)
Lifestyle Changes: we can always improve our lifestyle to counter CKD, getting enough
sleep 8-10 hours a day, Eating food and drinking water regularly, not having any junk
food or soft drinks/ soda, maintaining body discipline, working out, etc..
Healthy Diet: we can change our diet, a diet provided by your consultant or doctor, or
one that suits your body type, this will help decrease the effects of CKD and help
balance the state of your kidneys, such as consuming carbohydrates, protein, vitamins,
minerals and fiber.
No smoking and alcohol: smoking and alcohol can be really deadly if not immediately
stopped, smoking destroys your kidneys and lungs, and a slightly high amount of
alcohol can also affect your kidney in many ways which increases the seriousness of
CKD.
Having a medicine routine: Consuming prescribed medicine through the most efficient
way helps our body to not only be overdosed but then also helps the medicine to act
quickly helping out the body in many different ways.
3 ways CKD is controlled Its serious
Dialysis: When CKD has reached Stage 5, it is necessary to take actions such as
dialysis, dialysis is used for a time, planning if you will be needing a kidney transplant or
not, but dialysis itself is a very efficient way to counter CKD, dialysis is the method
where waste substances and materials are removed, There are two type of Dialysis:
Haemodialysis: Haemodialysis is the process in which blood from one’s body, being that
a needle is injected into one’s arm, that blood that is taken is then transferred into an
external machine or device that filters the blood for you, then it is transferred back into
the body using another tube, this makes the kidneys job easy the filter blood, as it
already coming back filtered, This is to be done as per consulted, some have to do it 4
times a week for 4 hours and come have to do it for 6 days a week for 8 hours
(overnight) it depends on how serious the matter is and what actions have to be taken in
order to control CKD. Hemodialysis risks include:
● low blood pressure
● anemia, or not having enough red blood cells
● muscle cramping
● difficulty sleeping
Peritoneal: CAPD is "continuous," machine-free and done while you go about your
normal activities such as work or school. You do the treatment by placing about two
quarts of cleansing fluid into your belly and later draining it. APD differs from CAPD in
that a machine delivers and then drains the cleansing fluid for you. This process is done
three, four or five times in a 24-hour period while you are awake during normal
activities. Other risks include:
● abdominal muscle weakening
● high blood sugar due to the dextrose in the dialysate
● weight gain
Kidney Transplant
End-stage CKD occurs when the kidneys have lost about 90% of their ability to function
normally. A kidney transplant is a surgery to place a healthy kidney from a living or
deceased donor into a person whose kidneys no longer function properly. The risks
associated with a kidney transplant include those associated directly with the surgery
and rejection of the donor organ.
Advantages of Dialysis
The advantages of dialysis are many, some of which are there is no waiting period, the
process of dialysis can start immediately, as in kidney transplant, one has to wait for a
donor. in Peritoneal dialysis, there is no need of a machine and it is easy to travel and
life expectancy also increases, there are no needles required, fewer diet restrictions.
Advantages of Kidney Transplant
There are more advantages than disadvantages for kidney transplants, few being:
patients live longer and healthy lives, There is no need of dialysis after a kidney
transplant higher energy and stamina, work and travel becomes easier, less diet
instructions.
