What causes sickle cell anemia?

Basically, sickle cell anemia means that some of the red blood cells of the person with the disease are not the right shape, instead of being bowl shaped, they are half moon shaped. This means that they can't carry oxygen around the body as well as a person without the condition. As the sickle cells are not only the wrong shape, but also quite rigid, they can block the blood capillaries, so that tissues in the body become starved of oxygen (ischemic). The blockages can vary loads in severity/frequency etc, and they can end up causing a stroke or heart attack if blocking a blood vessel to the brain or heart. One of the organs that is really badly affected by this is the spleen. It has really narrow blood vessels leading to it, so can get starved of oxygen badly and frequently. Normally this means that people with sickle cell anemia do not have a working spleen by the end of childhood, so are at risk of infections. People with sickle cell anemia tend to have more red blood cells than people without the condition as their body over compensates for the red blood cells.

How do you prevent the ailment of anemia?

The most preventable form of anemia is iron-deficiency anemia. In this case, it is important to eat foods rich in iron (or fortified with iron). In addition, taking Ferrous Sulfate tablets, as prescribed by a physician or nurse practitioner, would help to readily correct the problem of iron-deficiency anemia.

Vitamin B-12 deficiency anemia is another one that can be often treated with just B-12 supplementation (as directed by your doctor). However, if B-12 deficiency anemia is caused by lack of intrinsic factor (IF) in the stomach, then B-12 would need to be given by injection (in order to bypass the otherwise needed absorption of B-12 in the stomach).

Anemias due to blood loss require medical and, sometimes, surgical intervention. There are also a whole array of other anemias which require specific trreatment.

Consume a reasonable diet, adequate in protein and iron (as well as folic acid and vitamin B12).

Iron deficiency anemia, which is what I assume you are referring to, is most common among females because they lose lots of iron during menstruation. Vegetarians, woman with especially long periods, endurance athletes and pregnant woman are at higher risks. If you are not a vegetarian, you should try to eat lots of lean red meats in addition to leafy green vegetables as those are the the best sorces of iron. Red mean is a hema (animal) iron and vegetables is a non-hema (non-animal) iron. Hema iron is more easily absorbed by the body, but if you eat non-hema iron and hema iron in conjunction, it boost absorption of the non-hema iron. Vitamin C boosts absorption as well. So for example, if a person ate a steak or hamburger and a spinach salad and apple slices, they would be consuming a meal that is likely to boost their iron levels. If you are a vegetarian, you might substitute the burger for some type of red or white bean (beans are high in iron) or perhaps a tofu burger. Also, many cereals are iron fortified, and although they are the most easily absorbed form of iron, if you eat a bowl of cereal with a glass or juice you would be starting out your day well. You should just Google foods which are high in iron, print off a list, and stick it to your fridge so you can stalk up on iron rich foods next time you go to the store. In addition, I would recommend going to CVS or Walgreen's and getting slow-release Fe. Take one tablet a day if you are reasonably sized, probably one every other day if you are under 100 pounds - read the package.

What is pernicious anemea?

This is anaemia (lowered blood haemoglobin) due to a lack of vitamin B12 absorbed from the intestinal tract, due to a lack of intrinsic factor usually. This can be due to auto antibodies against the cells that produce intrinsic factor, stomach ulcers crowding out the cells that produce intrinsic factor, a hereditary lack of intrinsic factor or the after effects of surgery, illness or fish tapeworm. This gives a macrocytic anaemia. Pernicious anemia is an autoimmune disease that renders the person unable to absorb sufficient Vitamin B-12. Eventually the person becomes Vitamin B-12 deficient and must be treated. Prior to the availability of treatment persons died from the disease, hence the name pernicious. It is critical that treatment be obtained as soon as possible. You can find more information at the following website: www.pernicious-anaemia-society.org

What is the effect of iron deficiency?

Iron is a component of hemoglobin.

It's the iron that carries to O2 to your cells.

Low iron leads to anemia (low red cell count)

which leads to cardiac failure. When someone is anemic, they tend to be very fatigued...

Why does a person with anemia look pale?

Anaemia is a condition where the level of hemoglobin in the blood is below the normal range. Hemoglobin is the iron-containing molecule in red blood cells that carries oxygen around the body so, in anaemia, less oxygen is delivered to the tissues. Anaemia is an abnormal reduction in the amount of the oxygen-carrying pigment hemoglobin in the red blood cells which is probaly why people look pale. When you have less red blood cells then you will probaly start to feel tired and possibly cold.

What is the illness sickle cell anemia?

Sickle-cell Anemia, or Sickle-cell Disease, is a disease which is caused by a mutation in the animo acid sequence of the red blood cells.

The type of mutation occurs during the transcription of messenger RNA (e.g. GTC becomes CCG instead of CAG ). This change causes the mRNA to translate into a different amino acid (e.g. Valine instead of Glutamate ).

In this disease, the changes start in amino acids, the primary structure of proteins, thus changing all the higher protein structures. The red blood cells then will have a different shape, like a sickle.

These sickle shaped red blood cells will nor function normally. Thier shape disables them from flowing easily in the blood vessels, which might lead to further complications. Also, their life span is shorter than the normal cells, hence causing Anemia.

A chronic, inherited blood disorder characterized by crescent-shaped red blood cells. It occurs primarily in people of African descent, and produces symptoms including episodic pain in the joints, fever, leg ulcers, and jaundice.

Can sickle cell trait skip a generation?

yes it can skip a generation, since it is a Mendel inheritance. and it is a reccesive trait. therefore offspring's can have two unaffected parents but chances are both parents might be carriers

The genetic disorder sickle-cell anemia is an example of?

Well, its a genetic disorder that is most common among African Americans. It is when red blood cells are C shaped. It's an example of a problem

It is an example of pleiotropy.

What creates the loss of iron in anemia?

There are several things that can cause the human body to lose iron. Blood loss, a lack of iron in your diet, and an inability to absorb iron are all causes to losing iron. Pregnancy can also cause your body to lose iron.

What is a good anemia treatment?

Anemia or iron deficiency can be cured by eating foods high in iron (leafy greens especially spinach are great, other green veggies are good as well but spinach is the highest in iron). Also, if you have been diagnosed as anemic by a doctor they will often prescribe iron supplements.

Sickle cell anemia however cannot be cured, only treated.

Why do your arms fall asleep?

Your arm doesnt fall asleep that's just a silly way to say it, your arm needs blood to move. just like a few days ago my arm fell asleep cause i slept on it ( 7-5 hours straight) when i woke up my arm felt dead i tried moving my fingers but nothing, i tried moving my arm but i can just carry it along with me, my shoulder holding it up. it eventually "woke up" or i finally could move my fingers but not so easily then after atleast 1- 3 minutes my arm returned to normal. maybe you should try this, sleep on your arm when you wake up your arm should be asleep, if not then you move too much in your sleep, try another option, lay on your arm for atleast 10-20 minutes. if your patient. and get up your arm shouldn't be moving when you try to but yeah answering your question [ cause there isn't no blood circulation into it ] .

How can anemia lead to leukemia?

Anemia in any Leukemia is caused by the bone marrow not producing the proper amounts of red blood cells. Lymphoblastic Leukemia is a form of Leukemia that is caused by deficiencies in the Lymph system in our bodies. Cancerous lymph cells,tumors or other abnormalities can cause it. Possibly low platelet counts and low white blood counts accompany the low RBC

What happens to your body if you dont get enough riboflavin?

Vitamin B2, also called riboflavin, is one of eight B vitamins. B vitamins help the body to convert carbohydrates into fuel, or glucose, to produce energy. B vitamins also help the body metabolize fats and protein, and are necessary for healthy skin, hair, eyes, liver, and proper functioning of the nervous system.

Nursing diagnosis for patient with anemia?

It depends on what type of anemia the patient may have.

Iron deficiency anemia would have a nursing diagnosis of Imbalanced Nurtition: less than body requirements.

If anemia is caused by acute hemorrhage, restoring blood volume is the highest priority.

Activity Intolerance - inadequate oxygen delivery to the tissues can lead to weakness, fatigue, and shortness of breath with activity.

Folic acid deficiency anemia may have a diagnosis of Impaired oral mucous membranes r/t fluid deficit (folic acid deficiency anemia has gastrointestinal manifestations of glossitis, cheilosis and diarrhea).

decrease cardiac output

What kind of doctor specializes in anemia?

A hematologist specializes in the area of blood and bone marrow. These doctors are very essential in diagnosing and treating blood illnesses and cell count problems.

What are the disease that you get from eating junk food?

Junk food is bad for you because it's not healthy. Your body uses food and liquid as fuel. Eating junk food is like putting a bad fuel into your body. It's okay to eat a little bit of junk food once in a while, but eating a lot is going to cause problems. The body has to work extra hard and junk food causes a lot of bad things. You get more tired, and gain weight, but exercising and eating other healthy stuff well be fine!

Which ethnic group does sickle cell disease affect?

Black people have a genetic predisposition to sickle cell anemia. Recently there has been progress made in curing this horrible disease.

How many African Americans are carriers of the sickle cell disease?

Sickle-cell disease, usually presenting in childhood, occurs more commonly in people (or their descendants) from parts of tropical and sub-tropical regions where malaria is or was common. One-third of all indigenous inhabitants of Sub-Saharan Africa carry the gene, because in areas where malaria is common, there is a survival value in carrying only a single sickle-cell gene . Those with only one of the two alleles of the sickle-cell disease are more resistant to malaria, since the infestation of the malaria plasmodium is halted by the sickling of the cells which it infests.

The prevalence of the disease in the United States is approximately 1 in 5,000, mostly affecting African Americans, according to the National Institutes of Health.

What if man who is carrier for sickle cell amonia a recessive genetic disease non carrier women what proportion of their children are expected afflicted with sickle cell amonia?

I'm guessing you meant sickle cell anemia. You already said that it's recessive, which means that both parents have to be carriers for it to be passed on to their children. If both parents carry the gene, then there is a 1 in 4 chance of having an affected offspring, 2 in 4 chances of having offsprings which carry the disease, and 1 in 4 of the child being unaffected (check out how to draw a punnet square). If one parent is a carrier and the other one is healthy, then you have a 50% chance of having an offspring who carries the disease, but none of your offsprings will be affected. Hope this helps

Why is sickle cell important?

Sickle cell disease is important because it is a genetic disorder that affects the shape of red blood cells, leading to pain, anemia, and organ damage. It predominantly affects people of African, Mediterranean, Middle Eastern, or Indian descent. Early diagnosis and proper management are crucial to prevent complications and improve quality of life for individuals with sickle cell disease.

When was sickle cell anemia discovered?

Sickle cell anemia was first described in the medical literature in 1910 by Dr. James B. Herrick, who identified the unique sickle-shaped red blood cells in a patient of African descent. The genetic basis of the disease was later elucidated by Dr. Linus Pauling in the 1940s.

Who has a sickle cell trait?

People who inherit one sickle cell gene are said to have sickle cell trait. This means they carry the gene but do not typically have symptoms of sickle cell disease. It is important for individuals with sickle cell trait to be aware of their status for proper medical management and genetic counseling.

What is sickle cell anemia?

Sickle cell anemia is a disease passed down through families in which red blood cells are an abnormal crescent shape. Sickle cell anemia is a disorder of the erythrocytes (Red blood cells). It causes their normal biconcave shape to be replaced with that of a sickle or crescent. People with this disease have problems transporting oxygen throughout their bodies, as a result of this, they become fatigued easily and have rapid heart rates even when resting.

The difference between sickle cell trait and sickle cell disease?

It has to do with your genitic make up. You don't have sickle cell anemia because you only have 1 of the traits on your beta hemoglobin gene. People with sickle cell anemia have two.Most of the time peolple with sickle cell trait display much milder symptoms.

It is more prevolent in African Americans and woman should be monitored during pregnancy.
