Gout, despite the
level of understanding we gained through experience and advancement of medical
knowledge, is still an obscure medical condition. The locations of the next
gout attack is usually a mystery. Even the joints and non-joints it attacks is
covered in mist as well. In fact, even its complications are not fully
understood.
Here is another
weirdness to add to the long list: you can suffer from gout even if your uric
acid level is normal!
This article aims to
explain why people can suffer from gout despite the fact that they have normal
uric acid level.
Uric Acid Levels. What Does it mean?
Uric acid is the end
product of purine metabolism. Purine is
found all throughout your body since it is the building block of the DNA. All
cells have preprogrammed “self-destruction” called apoptosis. Furthermore, all
the foods you eat contains purine. Hence, purine will normally exist in the
body. Unfortunately for you, your body can not excrete purine. Purine has to be
broken down into uric acid to be excreted.
So, what does the
presence of uric acid indicate? Congratulations! You are a normal person. That
is, if the level of your uric acid is normal.
There are two ways two
test uric acid levels: one is through a uric acid urine test, and the other is
through a uric acid blood test. In a blood test, the normal uric acid level of
a male is 4.0 to 8.5 mg/dL. For females, the normal uric acid level is 2.5 to
7.5 mg/dL.
Uric acid urine test
is done by collecting your urine for an entire 24 hour period. The normal uric
level is supposed to be 250 to 750 mg per day.
Having above average
uric acid level is usually a sign of bad health, such as damaged kidneys,
hyperuricemia and gout!
Here is the catch: some
people, even if they fall perfectly within the bounds of those limits, suffer
from gout attacks. Others far exceed those normal values, yet they do not
suffer from gout. This is where the “gout black box theory” comes in.
The Gout Black Box Theory
It only takes a single
shot of beer for some people to suffer from gout attack, while others can
endure an all-night beer party without any joint pain. The reason for this is
the pathway of uric acid is like a mysterious black box, just like those used
in magic shows. The illusionist puts his hands in the box and voila! He draws
some random stuff from the box. The audience will never know what is happening
inside the box, just like how they will never know what will appear. A bunny? A
pair of bunny? Or maybe an alligator!? It is full of surprises! Just like how
you put too much uric acid in your body. You’ll never know how much uric acid
you will need to produce a negative result, and you’ll never know what you’ll
get. Gout? Gout in the fingers? Gout in the elbow? Gout in multiple joints?
Gout inside the ear? Or maybe diabetes!
The main point is the
“normal” uric acid level is not always normal for everyone. Your supposedly
normal uric acid can deviate from those recommended. The reason behind this is
the unique factors. Several aspects are to be considered for the precipitation
of gout and the ignition of pain and inflammation. There are two main reasons
why even people suffer from gout despite the normal uric acid level.
1.)
Your normal uric acid level is different from
the standard range – there is
a multitude of reasons behind this. For instance, the solubility of uric acid
may vary from individual to individual mainly because of the presence of
different solutes in the blood. For instance, a person with high sodium diet
has a lower supersaturation point for uric acid crystals. Hence, gout forms
easier!
It is
also possible that an individual has low glomerular filtration rate, or the
filtering capacity of the kidney. This lessens uric acid excretion rate. Such
conditions require medical attention because this may indicate some kidney
problems. This possibility is more likely if you have high uric acid serum
level but that of the urine is subpar.
The uric
acid output rate can also be reduced if your body is too acidic since the
excretory system have to take care of all those excess acids to balance the
body’s pH. For instance, the liver’s attentions is divided between granting
uric acid the clearance and converting lactic acid into glucose.
2.)
The uric acid is hidden- if both serum and urine uric acid is below
average and you get gout, this is the most likely reason. Chances are, the
tophaceous deposit has formed some time ago, hence the uric acid is in the
joint. Furthermore, to balance your body’s pH, the bod has to store excess
acids, such as uric acid to the interstitial space. This is not traceable
through ordinary serum uric acid test.
