The incidence of
Diabetes Mellitus ("Boal Sakar"
or"Sukar")
amongst Arabs varies depending on where they come
from. It occurs in increasing order of frequency
from Yemen, Dubai, Ras al Khymah, Sharjah, Abu
Dhabi, Oman, Bahrain, Saudi to Qatar, so much so
that from Qatar every second or third middle aged
or elderly person is likely to be a diabetic. In
Yemen it is a rare disease and when seen, it is
more in "Saudi" type of Yemenis. In
U.A.E., it is most common in Abu Dhabi. Most of the times
the disease is detected incidentally. Since no
sophisticated equipment is required for diagnosis
of diabetes, it is easy to pick up this disease
on a routine health check-up. Also many
practitioners ask for blood sugar examination,
when they associate many symptoms like weakness,
giddiness, malaise, impotency etc. to diabetes as
they do in case of hypertension. Unfortunately,
such symptoms are abundant in Arabs. On most of
the occasions these are not due to "mild"
diabetes (in fact glucose intolerance) only
detected incidentally as above. Often this fact
can be confirmed on a follow-up.
The
following are some observations made on this
diabetic population
- Even
with moderately severe diabetes, often
the symptoms of day time ("Finnhaar")
or night time ("Fillail")
polyuria are absent.
- Although
Arabs normally complain of dry mouth
("Iyaabus"),
but diabetics do not complain of
polydypsia or increased thirst.
- Polyphagia
is rarely complained of, because even
normally Arabs eat heartily.
- Many
Arabs complain of marked weakness, which
turns out to be psychogenic or of sexual
origin. But patients having moderately
severe or even severe diabetes often do
not complain of muscular weakness ("Daeef")
or fatigue ("Tahbaan").
- Loss
of weight is not a common complaint of
Arab diabetics.
- The
incidence of Diabetes is much more in
males.
- Pruritus
("Hakka")
a very conlmon symptom in the general
Arab population is hardly complained of
more by diabetics.
- Ketonuria
is very rare in Arab diabetics.
- As
regards sexual impotency, more often the
symptom appears to be of psychogenic
origin with the presence of normal
nocturnal tumescence ("Zib
Fillail Subah" "Mazboot").
Perhaps the severity is more marked
because of the dreaded fear of the
disease of diabetes. Unfortunately at
present in Bombay we have no facilities
to investigate impotence. Clinically if a
patient has evidence of peripheral
neuropathy or autonomic nervous
disturbances, then the impotence can be
considered as organic and due to
diabetes. In the rest, it is only on a
'follow-up' that one can confirm the
label of 'psychogenic'. Thus it is so
common to see a Saudi or a Qatari, who is
neither dieting nor taking proper
treatment for diabetes, and yet has
responded to "sex tonics".
- Microvascular
complications like diabetic retinopathy
or nephropathy are also very rare. It is
difficult to believe that "Allah"
(God) protects them from these
complications, inspite of suffering from
severe diabetes and not taking regular
treatment. It reminds me of the old days
when I used to read that Insulin therapy
lowers the sugar but
"increases" the process of
atheroma.
- Even
amongst the macrovascular complications,
the incidence of cerebral
arteriosclerosis resulting in stroke is
not so common. Stroke when seen is more
common in Saudis. (It is worth noting
that in Arab population, often, in
patients suffering from stroke, there is
no evidence of diabetes or hypertension).
Also coronary atheroma with resultant
symptoms of ischaemic heart disease is
less common than one should expect.
Arteriosclerosis of peripheral vessels of
limbs is not uncommon. But the symptoms
of claudication and gangrene, are
extremely rare compared to the severity
of diabetes and often, associated heavy
smoking. Minor foot problems are observed
especially in the poor class with poor
habits of hygiene.
- Balanitis
is unknown because of the practice of
circumcision.
- Although
Pulmonary Kochs is seen, off and on, in
Yemenis or U.A.E. patients, yet in most
of the diabetics, who mainly come from
other Arab countries, Kochs is a rare
complication.
- Complication
of carbuncle is rare.
- Premature
cataract due to diabetes is very
uncommon.
- Kidney
infections due to underlying diabetes
seem to be rare. Even if blood urea is
found to be elevated, often associated
prostatic enlargement turns out to be the
cause.
- The
only common complication seen is that of
peripheral neuropathy. Here again
sometimes it is difficult to diagnose
this complication clinically, because
even normal Arabs do complain of symptoms
of tingling and numbness ("Naum"),
burning ("Haar")
and pains ("Vajaa")
in the legs ("Rijley").
Unless the sense of vibration or the deep
tendon jerks are affected,
electromyography and nerve conduction
studies may have to be done to confirm
the diagnosis. Severe lancinating burning
pains of advanced diabetic neuropathy are
rare in Arabs. Similarly rare are the
other complications affecting the central
nervous system .
- An
Arab would always like to know the
details of his disease of diabetes
like
- Is sugar
present only in urine or only in
blood or in both?
- What are the
readings of fasting and
post-prandial blood sugar?
In
practice, we find that though some of the
pathologists still estimate venous blood
"sugar" by the Folin-Wu method,
others do
- Blood
"glucose" or
- "Serum
glucose" or
- "Capillary"
blood sugar or
- Glycosylated
Haemoglobin estimation.
Similarly
some pathologists do
"post-glucose" blood sugar,
while some others do the
post-prandial blood sugar estimation.
Amongst
those using "post-glucose" load
test, some use 75 G of glucose, others use
100 G. yet others use 1 G/kg of body weight.
Amongst food, no specifications are
mentioned. Some Arabs go after eating bread
and butter only. Others go after a full
breakfast or a "heavy" lunch. Yet
others go after consuming a tot of
"sweet meats" ("Haluwas"),
because they want to "try" and see
if blood sugar does get elevated with these.
After
the post-glucose load test or post-prandial
test, some pathologists call them after one
and half hours, others, after two hours and
yet others, after two and half hours. An
average Arab who goes to eat in a restaurant
or a hotel can hardly keep up the
"accurate" timing. And even when he
does reach the hospital in time, to this
should be added the average long
"waiting" time for a lift or an
elevator to reach the laboratory and finally
to find a technician to be ready to receive
him at any odd time.
Arabs
are known to try more than one laboratory
("Ayyadaa"),
lest there may be new machines ("Makinaa")
in other clinic. All these reports from the
various laboratories thoroughly confuse our
Arab visitor.
Naturally
the permutations and combinations of the
above circumstances would lead to variable
results.
- When
it comes to advise on diet, for an
average Arab, it is difficult to change
his main diet of rice ("Roz"),
plenty of bread ("Roti"
or "Ayesh"),
fat Chapatis ("Khubuz")
and meat ("Laaham").
They do not include high fibre diet of
vegetables, ("Khodraa")
and pulses ("Hadas"),
though a few of them do consume the
latter. The universal habit of eating
dates ("Khajoor"
or "Tamar")
even in severe diabetics cannot be
discouraged.
- (20)
Although, initially, they do not mind
insulin injections twice or even thrice a
day, within a few days or weeks, they
gradually begin to omit some doses,
finally omitting the in jections
altogether. Often "Ramadaan"
(when they observe a fast during the day
and avoid all food, cigarettes and
drugslasting over a month) is
responsible for discontinuation of
injections. At other, times, they stop
because they do not believe in
"long-term" therapy.
The same
applies to compliance with tablets. More
often they are happy to continue tablets
and prefer them to injections. But even
when at their best, the tablets are
consumed regularly, only for a few
months. They do not mind
"re-starting" when advised to
do so.
- Many
Arabs consume Diabinese (chlorpropamide)
tablets. I have never heard of the
history of an "Alcohol
Chlorpropamide" reaction in an Arab.
Now since we know that this reaction is
determined by the underlying HLA
antigen-pattern, in future it may be
possible to explain the rarity of this
"syndrome" in Arabs.
- Finally
I would like to stress that when these
patients come back for a follow up, I
find that though they are living happily
with the uncontrolled disease, without
developing much of the complications,
many of them have constant underlying
tension and anxiety of the disease and
are looking forward to come back to have
a check up for the "state" or
the "stage" or the
"control" of the disease.
And of
course this does not mean that all of them show
this behaviour. Those few, who were "symptomatic"
show a better compl iance.
Those
patients whose doctors have co-related their
"sex weakness" with diabetes are the
ones who come back again and again and go for
repeated check-ups of their blood sugar levels
till the specialist positively disconnects the
two diseases in their minds.
