Diabetes mellitus
A lot of people have diabetes and they live a long life with it. Diabetes can develop at any
age, but risk increases up to age 40. After age 30 it more commonly aects women than
men. Diabetes has been known for several thousand years. hen untreated, people with
diabetes could urinate fre!uently and copiously, therefore the "reeks named it siphon,
and later mellitus, meaning sweet. At that time, the diagnosis was made by tasting theurine, which was sweet. #he sweetness is caused by the presence of glucose in the urine.
$ts presence is useful in making the dierence between two forms of diabetes% mellitus
and insipidus. $nsulin is the lack hormone in diabetes, which in normal, is produced by
islets of &angerhans. 'ntil the (0thcentury, diabetes was a common cause of death. )ince
*+(*, new knowledge and techni!ues made it possible to do more for diabetics. Dr. lliot
-oslin of oston made a revolution in matter of diabetes. /e realied that the diabetes
patient needed to have understanding of his disease so that he could take care of himself.
#he patient and his family have to be well informed about the disease in order to make
day to day decisions about managing it.
1haracteristics. #he main problem in diabetes is the body2s inability of metabolie
glucose, which is a crucial process in ensuring the body2s cells with energy. "lucose is
stored under normal conditions in the form of glycogen and reconverted into glucose
when it is needed. #he insuciency of insulin leads to body2s inability to metabolie
glucose, which results in an abnormal accumulation of glucose in the bloodstream. #he
failure is similar to starvation. #he diabetic eats food but cannot use the energy,
therefore, in order to obtain energy, the people has to metabolie the stored fat. #his
results in loss of weight. A by product of fat metabolism is ketone bodies which may
produce diabetic acidosis.
cess urine production% as glucose accumulates above normal levels in the diabetic2sbloodstream, it is 5ltered by kidneys and remains in the urine. #he ecessive urine is
produced in order to eliminate the ecess of glucose in the blood.
$n diabetes, the glucose, protein, fat metabolism are aected, which produce changes in
the nerves, muscles, eyes, kidneys, blood vessels. #his disease may be mild, moderate
and severe, and nobody knows the eact causes. Diabetes worse in the presence of
illness, hyperfunctioning diseases, stress and during pregnancy.
#he diagnosis of diabetes is an easy one, especially in children, the symptoms are
evident% rapid weigh loss, etreme hunger, general weakness, fre!uent and copious
urination, ecessive thirst. 6inding glucose in the urine along with increased levels of
glucose in the blood generally con5rms the diagnosis. 7oreover, an adult of diabetes may
not have an evident set of symptoms for months, years. /e may 8ust have fatigue, or
skins infections. A woman may have a genital itch 9prurit:.
#he diet is a ma8or part of the treatment. #he patient should reduce the calories in the
food. Diet is the only treatment needed by many adult diabetics, especially those who are
obese ;obi

containing concentrated sugar. )ome people may use diet guides, which indicate number
of calories and amount of protein, fat, carbohydrate.
'ntil recent years, insulin was prepared in the ') from beef or pork pancreas. =owadays,
the insulin drug is manufactured synthetically; sinthetikli< using a duplicate of human
genes. $nsulin has to be given my in8ection, usually subcutaneous in8ections, because the
insulin may be destroyed by gastric secretions, if taken orally. $nsulin infected once a dayshould mimic normal insulin action, which is the purpose of the intermediate and long>
action insulins. ?ther people re!uire two or more in8ections. #he usual time taking is
before breakfast and should be the same time every day. )econd in8ections is at supper
time. #he basic insulin dose is established according to the severity of the disease.. most
diabitics take *0>40units per day.
7ost diabetics self in8ect their insulin and the site of in8ection should be changed
everyday. Insulin shock.#he in8ected insulin much be matched
to the amount of blood sugar. $f there is too much insulin, too much eercise, or too little
ingested carbohydrate, the blood sugar level rapidly falls, a condition known
hypoglycemia; haipoglaisimi@< and the brain is deprived of energy. $t occurs at the time of
the insulin2s peak activity, resulting in insulin shock. #he 5rst sing is mild hunger, then
!uick sweating, palpitation, shallow breathing, mental confusion, loss of consciousness. $n
this case, the patient should be oered sugar, or intravenous glucose. Diabetes who use
insulin should always have a lump of sugar in order to avoid the insulin reaction.
epeated and prolonged episodes of insulin reaction may be damaging to the brain.
Development of a pump for infusion of insulin into the body2s bloodstream is a method of
treating diabetics with keto>acidosis. $n this method, a reduced amout of hypoglycemia
has been reported. $t includes a reservoir for insulin, a pump, and a Bpower pack2
containing batteries. #his method meets the physiological needs of the body. Oral
hypoglycemic drugs are useful in controlling mild diabetes that develops in people over
4C. $n order this method to work, some of the islets cells must be capable to produce
insulin, because the drugs stimulate their activity. #he dose varies from *> pills taken
before meals and throughout the day. Prolonged
hyperglycemia, caused by ecess of sugar, from insucient insulin activity, can cause
diabetic coma. $t involves the increased amount of ketone bodies as a by product of fat
metabolism> a chemical imbalance in the blood. $f we 5nd a diabetic in coma, and we
don2t know the cause, we should treat him with sugar and it will give an insulin reaction.
Diabetic acidosis occurs due to% the patient didn2t take the insulin for some days, take too
little, overeate or undereercise. #he treatment involves taking rapid>acting insulin every
3>4 hours.Diabetes re!uires a good control, which means feeling well with small amount of sugar, or
no sugar in the urine. #he patients should take personal glucose tests, to control their
urine daily, namely, in the beginning of the day. #he tests oer information about the
eciency of their diet and eercise and insulin activity. ?nce the patient
has made crucial ad8ustments, related to his diet, insulin intake, and planned his daily
activity, he is on his way to a normal life. /owever, there may be obstacles, like the
acceptance, initial depression, maintaining the schedule in parties and during traveling.
Also, the family2s lifestyle should be changed entirely. Juvenile[ djuvenail]

vegetables, eggs supply the growing organism with nutriets, peanut butter, whole grains
and honey instead of sugar.
Fregnancy is special for a diabetic woman and her unborn child. ut with good
management during diabetic2s pregnancy, the baby has an ecellent chance of being
normal and healthy. #herefore the diabetic mother need to be tested more often by the
obstetrician, controlling the urine glucose and blood glucose levels.
GGDiabetes is usually compared to aging, due to a loss of elasticity in the cells of theblood vessels, kidneys, eyes, nerve tissues. #he nerve>tissue changes may cause a
reduced sensation to touch and pain, loss of motor function. #he eye>ground changes can
cause loss of vision. #he changes of kidneys aect the 5ltration functions, loss of protein
from the blood into the urine, development of high pressure. 7edicine can reduce the

#he medical interview is the most important tool of the physician. $t is done more often
than anything in the physician2s professional life. #he functions of the medical interview
are% to gather and to communicate information, to develop and maintain a therapeutic
relationship. ach function re!uires a speci5c behavior and a separate set of skills.
1ollecting information is the base function of the medical interview. hether this
information is physiological or biological, appropriate collection skills can increase the
eciency of the information that is collected. #he main steps of the conversationbetween patient and physician is to gather information and determine ;d@t@rmin< the
nature of the problem. #he re!uired skills are% open>ended !uestion 9tell me about..: ,
facilitation 9help the patient to continue, encourage:, direction9want to know more about
it:, , summariing and checking the worries.
A therapeutic relationship means a relationship that promotes care, cooperation, healing.
#he good interaction between patient and physician, gives the patient freedom to talk
openly and in more detail about hisEher feelings. #he interviewing techni!ues such as
reHection, legitimation, support, respect, partnership, empathy, positive regard,
avoidance of shame and humiliation and nonverbal skills contribute to intervieweciency. $n order to maintain a good relationship, the physician needs to handle the
patient2s emotions. #he physician should be attentive and aware of whether the emotions
become evident and when they have to be but they are not. Also the physician must
involve the patient in making decisions. #his fact would make the patient more
responsible for hisEher health and may improve the biological outcome. Fatients who are
understood by their physicians are satis5ed and feel better, and the physician is satis5ed
in turn. #he physician should establish baseline knowledge and attributions by asking the
patient to tell what heEshe knows about hisEher disease. Also he should avoid comple
medical terminology, and check the patient2s understanding and attention by asking him
to summarie the information. $n this way, the patients will better understand the natureof their illness, the diagnostic procedures, and the treatment. #he information provided
by physician should be brief and concrete. #he patient may be anious and therefore,
may not be able to understand the physician2s message. in this way, the physician must
follow some points 9to the structural elements of the interview:% optimiing the
environement, opening, preparing to listen, greeting, the introduction, identi5cation of
the barriers of communication, survey the problems, negotiate the problems, establish a
narrative thread, developing the life contet of the patient and illness.

distractions, ensuring privacy, making eye contact. Also, having nice telephone operators.
