Anemia is defined as a condition
of deficiency of hemoglobin, leading not enough red blood cells in the
body. The functions of hemoglobin is to carry oxygen from the lung to
the body' s cells.
Causes of Anemia
There are many causes of anemia, including
1. Poor nutrition
In
some parts of the world, anemia is caused by iron deficiency due to
less meat in the diet. People who are vegetarian may want to supplement
their iron in plant with intake of vitamin C to enhance the absorption
of Non heme iron.
2. Poor absorption
Poor absorption of iron, vitamin B12 and folate increases the risk anemia.
3. Blood loss during surgery
In some cases, temporarily anemic condition may occur as a result of large blood during surgery.
4. Bleeding
Internal
bleeding due to diseases or cancers increase the risk of anemia. Some
women with heavy menstruation may be at risk of anemia.
5. Cancer treatment
Cancer
treatment such as chemotherapy can cause anemia because of medicine
used prevent the body in production of red blood cells.
6. Drugs use to treat HIV/AID
Certain medicine used to treat HIV/AID are considered another cause of anemia.
7. Kidney disease
Kidney disease interferes with production of hormone erythropoietin, which is necessary for the production of red blood cells
8. Heredity
Certain types of anemia are caused by genetic passing through from parents such as thalassemia, sickle cell anemia.
9. Etc.
Symptoms
1. Fatigue and loss of energy
2. Unusually rapid heart beat, particularly with exercise
3. Dizziness
4. Weak and tired easily
5. Shortness of breath
6. Difficulty concentrating
7. Pale skin
8. Insomnia
9. Irritability
10. Etc.
Diagnosis
Family history is always important for diagnosis of any disease, including anemia
Complete
blood count is one of most efficient test to checks your hemoglobin and
hematocrit levels. Low levels of hemoglobin (Normal range in men 140
-180g/L, in women 120-160g/L) or mematocrit ( the percentage of blood
volume that is occupied by red blood cells. It is normally about 45% for
men and 40% for women) is a sign of anemia.
Treatments
Treatment
of anemia depending to its causes, it can be supplement prescribed by
the doctor, blood transfusion, change of diet, bone marrow transplant,
etc.
Effects of anemia
1.
Symptoms of dizziness, lack of concentration, irritability may
interfere with job efficiency, sport activity, etc. for adults, mental
growth and psychomotor development for children with the risk of that
may be irreversible and school work and activity for children and teen.
2.
Anemia and kidney disease increase the risk of heart failure as a
result of the heart have to work over a prolong period of time to pump
blood to the body cells need.
3. Levels of hemoglobin
Researcher found that levels of hemoglobin have a direct effect in reducing the risk of cancer recurring.
4.
In general, anemia has a negative effect on quality of life and
cognitive function, as well as many other aspects of patient function.
A. Anemia and surgery
People
with anemia are at risk during and after surgery due to not enough of
red blood cells and sometime it can cause perioperative anemia as a
result of losing too much blood, leading to insufficient hemoglobin to
carry oxygen and nutrients for our body's organs and cells need.
Benefit of treating Anemia before surgery
If
you are required surgery for whatever reasons, there are something you
should consider to prevent complication during and after surgery.
Increase
your red blood cells count or raise level of hemoglobin will reduce the
need for blood transfusion during surgery, especial surgery that result
in heavy blood loss.
a. Intake of foods with rich of folate, vitamin B12 and iron such as peas, lentil, soybeans and chickpeas, etc.
b. Vitamin C
Vitamin
C is vital for the absorption of iron by increasing intake of vitamin C
rich vegetables and fruits such as kiwi fruit, strawberries, and
cantaloupes.
To increase to red blood cells, your doctor may prescribe
c. Erythropoiesis-stimulating Agents
ESAs
are given by injection or intravenously (through an IV) to stimulate
the bone marrow to produce more red blood cells, thus raising the level
of hemoglobin.
d. Contraceptive pill
Women who take the pill have reduced bleeding during period.
e. Etc.
It
is important that you increase your red red blood cells well before the
surgery to avoid the needs of blood transfusion, stay in hospital
longer and your incision heal faster.
Types of blood transfusion if necessary
You
surgeon will suggest some of the best options for blood transfusion if
necessary during surgery, please make sure you well understood and make
your choice
1. Autologous transfusion
This may be a good choice,
it is a blood transfusion that uses you own blood that has been previous
stored, donated before the surgery, during an operation or
post-operation.
2. Allogeneic transfusion
The type of blood transfusion with the use of donated blood
3. Collect and return
With
the use of a special medical machine to collect your blood during or
before surgery, then return them to your body following surgery.
4. Etc.
Blood loss minimization
Minimizing blood loss is always be considered for the best of the patient, especially for patience with anemia.
1. Lower blood pressure
Lower blood pressure helps to slower the blood flow, thus reducing the blood loss during surgery.
2. Position you body to reduce the blood flow, thus reducing the blood loss during surgery.
3. Using special medical instruments to minimize incision and control blood loss.
Etc.
B. Anemia and Cancer
Cancer is defined as condition of malignant tumors during abnormal cells growth as a result of alternation of cells DNA.
Under
normal condition, if you blood cell is low, you kidney responds to the
condition by stimulating the production of hormone erythropoietin to
signal bone marrow to increase production of more red blood cells.
Causes of anemia in cancer patient
1. Organ deficiency
In case of cancer patient the process of above may be less effective due to organs insufficiency.
2. Chemotherapy
One of the side effect of chemotherapy is the preventing of your body in production of red blood cells.
3. Bone marrow deficiency
Due
to cancer cells have spread to the bone marrow by certain types of
cancers, such as leukemias, lymphomas, myelomas and breast cancer can
reduce the bone marrow function in red blood cells production.
4. Nutrients deficiency
Poor absorptions in cancer patient is one of the causes of anemia due to deficiency of folate, vitamin B12 and iron.
5. Bleeding
Cancers in the gastrointestinal and genitourinary tracts can cause bleeding of the surrounding tissues.
6. Etc.
After thought
Researchers
found that increases the levels of hemoglobin and red blood count
responds better in cancer treatments. High levels of red blood cells
count and hemoglobin reduce the risk of recurring cancer.
C. Anemia and Immunodeficiency syndrome AIDS
Immunodeficiency
syndrome AIDS is caused by Human immunodeficiency virus HIV, a
lentivirus. It is defined as a health condition in which in which severe
failure of the immune system in protecting our body from infection and
irregular cell growth, leading to life-threatening infections and
cancers.
Anemia is a very common with people with HIV positive
and the rate increases as the progression of the disease progression.
Study found that approximately 30% of HIV positive people have anemia
and 90% will have anemia at some point during their life time.
Anemia and HIV infection
1. HIV infection reduces the production of erthroprotein in stimaulating the production of red blood cells.
2. HIV infection affects the bone marrow function in production of red blood cells
3. Medicine use to treat HIV-infection may reduce the bone marrow function in red blood cells production.
4. HIV infection patient may be at risk of lymphoma, a cancer which may spread to the bone marrow.
5. Infection
Infection may suppress the bone marrow in production of red blood cells.
6. Nutrients
HIV infection prevent the digestive system in absorbing folate, vitamin B12 and iron, causing anemia.
7. Etc.
Research
found that increasing levels of hemoglobin has a direct affect in the
increasing survival of a person with HIV infection.
D. Anemia and Hepatitis C
Hepatitis
C is a health condition of infectious disease affecting the liver that
may cause inflammation of the liver. Approximate 1.5% of the U.S.
population is infected with HCV. Once establish, the chronic infection
may progress slowly, after many years it can lead to scares in the
liver, causing fibrosis, cirrhosis and liver failure.
Causes of anemia in hepatitis C patient
1. Medication
Medication
used to treat hepatitis C, such as Ribaverin often cause mild anemia
with no treatment required. In other treatment, use of interferon can
suppress the bone marrow function in production of red blood cells.
2. Cirrhosis
Cirrhosis
is advanced scarring of the liver caused by hepatitic C virus. it can
reduce the spleen function in production of reb blood cells or cause
spleen to remove too many blood cells.
3. Bleeding
Cirrhosis can also promote bleeding of the gastrointestinal tract.
4. Etc.
After thought
Since approximate 67% of patients will develop anemia when ribavirin and/or interferon is/are used to treat HCV,
1.
Increasing red blood cells count is always important for the
effectiveness of full dose of ribavirin and/or interferon in treating
the diseases. Study showed that medicine used to stimulate red blood
cell production are effective in treating anemia in people with
hepatitis C.
2. If anemia left untreated, treatment of HCV with
lower doses of ribavirin and/or interferon may reduce the effectiveness
of the medicine or you doctor may discontinue treatment altogether.
E. Iron deficiency and anemia
Iron
is defined simply as too little iron in the body for the production of
hemoglobin. Anemia occurs when there isn't enough hemoglobin to
transport oxygen to the body cells and organs need, leading to symptoms
of irritability, fatigue, shortness of breath, low blood pressure, etc..
Approximate 2 out of 1000 people in Canada are considered iron
deficiency. If your body delete the stored iron, it can cause no
hemoglobin is produced, leading to iron deficiency anemia.
Causes of iron deficiency
1. Heavy menstruation
It may lead to iron deficiency if your body stored iron is depleted and your diet is considered low in iron.
2.
Chronic internal bleeding usually caused by ulcers, polyps, or tumors
can lead to low levels of iron stored in the body, leading to low levels
of hemoglobin.
3. Nutrient deficiency
Diet low in folate, vitamin B12 and iron can increase the risk of iron deficiency.
4. Poor iron absorption due to inflammation.
5. Etc.
Iron deficiency can be detected with a blood test.
Foods contain high amount of iron
there are 2 types of iron in the foods
1. Heme iron
This
type of iron is easily absorbed by our body and Foods contain high
amount of heme iron are found in meat of all sources, including liver,
beef, turkey, chicken, etc.
2. Non heme iron
This type of iron is
not easily absorbed. Foods contain high amount of non heme iron are
found in brocoli. spinach, soybean, kidney bean, etc.
Iron
supplement such as ferrous sulfate, ferrous furmarate, etc. should only
be taken with doctor subscription. Overdose of iron can be toxic to the
body and has some side effects, such darken stool, constipation, stomach
upset, etc.
How to reduce the risk of iron deficiency
1. Vitamin C
Vitamin
C can enhance the digestive system in iron absorption. Foods contain
high levels of vitamin C include broccoli, spinach, kiwi fruits,
strawberry, etc.
2. Adding Heme iron in your diet
In take of meat, poultry, fish will increase the levels of iron due to its easily absorption nature
3. Coffee, tea and cocoa can reduce the iron abortion significantly.
4. Calcium and magnesium can reduce you body in iron absorption. If you are required to take them, take them at different time.
5. Etc.
F. Anemia In Teen and Children
In
anemia, symptoms of early stage may be invisible to parents until it
is progression state. If you notice any above symptoms of above with a
pale face, taking your childern or teen to the doctor office and a
blood test will review with correct interpretation.
Causes of anemia in Children and Teen
1. Infection
Chronic
inflammation and infected virus will reduced the body in production of
hemoglobin which is necessary in oxygen transportation.
2. Heredity
If
you children and/or teen are diagnosis with certain chronic anemia
such as Thalassemia, Sickle cell anemia due to inherited or genetic
defects, intake of high amount of iron rich vegetables, fruits and some
lean meat over a period of can help, or taking some supplements
prescribed by your doctor.
3. Early infancy from 0 to 6 months
Most
children born with 6 months of iron stored in their body without
inherited anemia. After six months, if you are feeding your baby with
breast milk, please make sure there is enough iron for the body needs,
talk to your doctor will help to solve the problem. Infants born
premature may be required intake of iron supplements or iron fortified
formula depending of bottle feeding or breast feeding.
4. Teenager
Teenager
under go growth spurt and teenage girl starts to menstruate will
require intake of higher amount of iron either through diet ot iron
supplements to avoid iron deficiency cause of anemia.
5. Nutrient deficiency
Deficiency of folate, vitamin B12 and iron increases the risk of anemia. Intake vitamin C will enhance the absorption of above.
6. Etc
Some general treatments
1. Diet
Diet with foods containing high amount of iron is always good to reduce the risk of anemia.
2. Low fat diet
Low
fat diet is good for children, but starting low fat diet to your
children too early in their life, it can increase the risk of anemia due
to iron deficiency
3. Avoid giving cow's milk up to 12 months
Digestive system is not strong enough to digest them, thus reducing the nutrients absorption, including iron.
4. Cereal and iron fortified formula
Cereal
contains high amount of iron, it is specially for women who breast
feeding their infants. While feeding children with iron fortified
formula after six months provides necessary iron which had been used up.
5. vitamin C
taking vitamin C with your diet will enhace the absorption of vital nutrients, including iron.
6. Iron supplements
Iron supplement should be only taken with your doctor prescription. Overdose of iron supplements is toxic to your body.
7. Blood transfusion
If necessary and you doctor will advice you about
8. Etc.
G. Anemia can be classified into acute and chronic anemia
Anemia due to chronic disease
is a types of blood disorder as a result effected by one or more
chronic medical condition(s), causing reduced red blood cells
production.
Acute anemia
denotes as short term drops of red blood red cells production. Most of
the times, it is caused heavy internal bleeding or blood loss due to
injure. It is a serious problem, in most cases, it requires medical
attention immediately.
Diagnosis
Anemia
can be classified 3 different categories due to its causes of
decreased red blood cell production, increased red blood cells
destruction, and blood loss.
In chronic anemia, a simple blood test will review the underlie of the causes
1. Chronic anemia with iron deficiency
In
this case, the levels of ferritin found in the test is normal or high
but the cells are not releasing their iron because in iron deficiency
anemia, the levels of ferritin is lower than normal.
2. Chronic anemia with iron deficiency
The levels of total iron-binding capacity (TIBC)
should be lower in chronic anemia with iron deficiency, as it reflects
the inability the body to produce more transferrin, making bind up of
iron not necessary.
Types of chronic diseases that cause chronic anemia
If
you are in medical treatments of any chronic disease, you may be given
all kinds of information related to its affects, including anemia.
Sometimes prescription is given ahead of time to prevent anemia before
it can happen, other time, you may require to take some types of
supplements or drugs, depending to your situation. There are many types
of chronic diseases associated with anemia
1. Autoimmune Gastritis
Gastritis inflammatory condition of the stomach as a result of injured respond of white blood cells in the stomach. If the disease is left untreated, it can lead to chronic condition, causing pernicious anemia.
2. Peptic ulcer
Peptic ulcer is defined as a condition of erosion
of the lining of the stomach or the first part of the small intestine.
It can lead to internal bleeding, causing chronic anemia, if left
untreated.
3. Liver disease
Liver disease as a result of alcohol
drinking can cause Macrocytosis, a condition of enlargement of red blood
cells with near-constant hemoglobin concentration, leading to
pernicious anemia. Other liver disease caused by hepatitis virus, can
lead to decrease red blood cell count (hemoglobin), causing chronic
anemia.
4. Kidney disease
kidney disease can affect the production
of hormone erythropoietin, leading to reduced signal to bone marrow
for increase production of more red blood cells.
5. Hypothyroidism
Hypothyroidism
is defined as condition of deficiency of thyroid hormone. the main
cause is due to Iodine deficiency, leading to iron-deficiency cause of
chronic anemia, if left untreated. (insufficient iron)6. Sickle cell disease
It is an genetic blood disorder
disease passing from generation to generation with a abnormal red
blood cells shapes as a result of a mutation in the haemoglobin gene.
7. Hypermenorrhea
Hypermenorrhea
or ecessive heavy menstruation can be caused either by (uterine
bleeding) hormonal disorders associted with absolute or relative
hyperestrogenism due deficiency of progesterone or fibroid tumors
(uterine leiomyomata), polyps and cancer
8. Thrombocytopenia
Thrombocytopenia is a disorder of abnormally low amount of platelets, leading to with abnormal bleeding.
9. Cancer
More information here
10. Poor diet
More information here
11. Iron deficiency
More information here
12. Etc.
Types of chronic anemia
1. Microcytic, hypochromic anemia
Microcytic,
hypochromic anemia is defined as a chronoc anemia caused by many
conditions including iron deficiency, Beta-Thalassemia trait, lead
poisoning, chronic illness or inflammation, and sideroblastic anemia
(Korones & Cohen, 1997; Wu et al., 2002)
2. Macrocytic anemia
Macrocytic
anemia is defined as a condition of not having enough healthy red
blood cells in body to transport oxygen and nutrients to the body
tissue and organ as a result of insufficiency of vitamin B12.
3. Normocytic anemia
Normocytic
anemia is a common disease, occurring to men and women over 85 years
old as a result of low red blood cell volume as result of a decreased
production of normal-sized red blood cells, an increased destruction or
loss of red blood cells, deficiency of vitamin B6, B12, etc.
4. Hemolytic anemia
Hemolytic
anemia is defined as a condition of not enough red blood cells in the
blood, as a result of the premature destruction due to abnormal
breaking down of red blood cells (hemolysis) either in the blood
vessels or elsewhere in the body.
