Diabetes Symptom and Diagnosis
What are the different types of diabetes?
There are
two major types of diabetes, called type 1 and type 2. Type 1 diabetes was also
formerly called insulin dependent diabetes mellitus (IDDM), or juvenile onset
diabetes mellitus. In type 1 diabetes, the pancreas undergoes an autoimmune
attack by the body itself, and is rendered incapable of making insulin.
Abnormal antibodies have been found in the majority of patients with type 1
diabetes. Antibodies are proteins in the blood that are part of the body's
immune system. The patient with type 1 diabetes must rely on insulin medication
for survival.
In
autoimmune diseases, such as type 1 diabetes, the immune system mistakenly
manufactures antibodies and inflammatory cells that are directed against and
cause damage to patients' own body tissues. In persons with type 1 diabetes,
the beta cells of the pancreas, which are responsible for insulin production,
are attacked by the misdirected immune system. It is believed that the tendency
to develop abnormal antibodies in type 1 diabetes is, in part, genetically
inherited, though the details are not fully understood.
What are diabetes symptoms?
·
The early
symptoms of untreated diabetes are related to elevated blood sugar levels, and
loss of glucose in the urine. High amounts of glucose in the urine can cause
increased urine output and lead to dehydration.
Dehydration causes increased thirst and water consumption.
·
The
inability of insulin to perform normally has effects on protein, fat and
carbohydrate metabolism. Insulin is an anabolic hormone, that is, one that
encourages storage of fat and protein.
·
A
relative or absolute insulin deficiency eventually leads to weight loss despite an increase in appetite.
·
Some
untreated diabetes patients also complain of fatigue, nausea and vomiting.
·
Patients
with diabetes are prone to developing infections of the bladder, skin,
and vaginal areas.
·
Fluctuations
in blood glucose levels can lead to blurred vision. Extremely elevated glucose
levels can lead to lethargy and coma.
How is diabetes diagnosed?
The
fasting blood glucose (sugar) test is the preferred way to diagnose diabetes.
It is easy to perform and convenient. After the person has fasted overnight (at
least 8 hours), a single sample of blood is drawn and sent to the laboratory
for analysis. This can also be done accurately in a doctor's office using a
glucose meter.
·
Normal
fasting plasma glucose levels are less than 100 milligrams per deciliter
(mg/dl).
·
Fasting
plasma glucose levels of more than 126 mg/dl on two or more tests on different
days indicate diabetes.
·
A random
blood glucose test can also be used to diagnose diabetes. A blood glucose level
of 200 mg/dl or higher indicates diabetes.
When
fasting blood glucose stays above 100mg/dl, but in the range of 100-126mg/dl,
this is known as impaired fasting glucose (IFG). While patients with IFG do not
have the diagnosis of diabetes, this condition carries with it its own risks
and concerns, and is addressed elsewhere.

What is diabetes?
Diabetes mellitus is a group of metabolic diseases
characterized by high blood sugar (glucose) levels that result from defects in
insulin secretion, or its action, or both. Diabetes mellitus, commonly referred
to as diabetes (as it will be in this article) was first identified as a
disease associated with "sweet urine," and excessive muscle loss in
the ancient world. Elevated levels of blood glucose (hyperglycemia) lead to
spillage of glucose into the urine, hence the term sweet urine.
Normally, blood glucose levels are tightly controlled by
insulin, a hormone produced by the pancreas. Insulin lowers the blood glucose
level. When the blood glucose elevates (for example, after eating food),
insulin is released from the pancreas to normalize the glucose level. In
patients with diabetes, the absence or insufficient production of insulin
causes hyperglycemia. Diabetes is a chronic medical condition, meaning that
although it can be controlled, it lasts a lifetime.
What is the impact of diabetes?
Over time, diabetes can lead to blindness, kidney failure,
and nerve damage. These types of damage are the result of damage to small
vessels, referred to as microvascular disease. Diabetes is also an important
factor in accelerating the hardening and narrowing of the arteries
(atherosclerosis), leading to strokes, coronary heart disease, and other large
blood vessel diseases. This is referred to as macrovascular disease. Diabetes
affects approximately 26 million people in the United States, while another 79
million gave prediabetes. In addition, an estimated additional 7 million people
in the United States have diabetes and don't even know it.
From an economic perspective, the total annual cost of
diabetes in 2011 was estimated to be 174 billion dollars in the United States.
This included 116 billion in direct medical costs (healthcare costs) for people
with diabetes and another 58 billion in other costs due to disability,
premature death, or work loss. Medical expenses for people with diabetes ate
over two times higher than those for people who do not have diabetes. Remember,
these numbers reflect only the population in the United States. Globally, the
statistics are staggering..
Diabetes was the 7th leading cause of death in the United
States listed on death certificates in 2007.
Diabetes facts
Diabetes is a chronic condition associated with abnormally
high levels of sugar (glucose) in the blood.
Insulin produced by the pancreas lowers blood glucose.
Absence or insufficient production of insulin causes
diabetes.
The two types of diabetes are referred to as type 1 and type
2. Former names for these conditions were insulin-dependent and
non-insulin-dependent diabetes, or juvenile onset and adult onset diabetes.
Symptoms of diabetes include increased urine output, thirst,
hunger, and fatigue.
Diabetes is diagnosed by blood sugar (glucose) testing.
The major complications of diabetes are both acute and
chronic.
Acute complications:
dangerously elevated blood sugar (hyperglycemia), abnormally low blood sugar
(hypoglycemia) due to diabetes medications may occur
Chronic complications:
disease of the blood vessels (both small and large) which can damage the feet,
eyes, kidneys, nerves, and heart may occur
Diabetes treatment depends on the type and severity of the
diabetes. Type 1 diabetes is treated with insulin, exercise, and a diabetic
diet. Type 2 diabetes is first treated with weight reduction, a diabetic diet,
and exercise. When these measures fail to control the elevated blood sugars,
oral medications are used. If oral medications are still insufficient, insulin
medications and other injectable medications are considered.
