How did anemia get its name?

The name holds Latin roots. An- means without. Hema means blood. Basically, Latin gives the basic definition of Anemia. Without Blood.

What can iron deficiency be a sign of?

Iron deficiency can be a sign of a more serious problem, such as internal bleeding so it is important to get a thorough evaluation from a physician.

In sickle cell what amino acid is changed?

Glutamate is substituted for a valine at position 6.

But this is not an amino acid problem, it's the construction of hemoglobin that's in error.

Is sickle cell anemia recessive or dominant?

Sickle cell anemia is an autosomal recessive disease. Carriers have sickle cell trait, which confers resistance to malaria.

Why do you always feel like you have to cough up mucus but you never can get any up?

A genetic disorder called 'Cystic Fibrosis', maybe responsible for the over production of mucus. Otherwise, production of mucus is your bodies reaction to dust or other elements that could damage the lungs. The part of the airway that allows the mucus to move up, is called the cilia (tiny hairs that brush the mucus up away from the lungs) which may be damaged not allowing the mucus to travel up and out the airway. The cause of not being able to get rid of mucus or it being too thick could also be because of your water intake. The higher the intake, the thinner the mucus and also the more regularly the mucus is cleaned.

Can you explain what evolutionary advantage mean and how it accounts for why sickle cell anaemia is still so widespread in Africa?

evolutionary advantage means that if you have to types of sickle cell anaemia and one is resistant to a drug the the other one is not then the one that is not resistant dies off and the sickle cell anaemia that is resistant becomes dominant and that is why sickle cell anaemia is still so widespread in Africa because the strain that is widespread in Africa is resistant is anti-biotics.

How do you differentiate sickle cell trait from sickle cell disease?

Sickle cell disease is a chronic illness that comes from two parents who have sickle cell trait. This disease can be passed on if both parents have a sickle cell trait & gives that child each trait. The sickle cell trait is important because one must know if he/she is a carrier. If you carry this trait, most likely you will not be sick. It is only when you have children that knowing if you carry the trait is vital. Your child could be born with a painful, chronic, underexposed illness that will require that you have more knowledge than most doctors. Arm yourself with knowledge & get ready for a long fight for justice.

What is Refractory anemia?

Bone marrow with less than 5% blast cells and abnormal red blood cell blasts

Which supplements would most likely be recommended for someone suffering from anemia?

Supplements recommended for anemia are based on the cause. Recommending supplementation without knowledge of the underlying cause may be dangerous in some cases. For instance, a patient with B12 deficiency will not recover if given iron.

How is homeostasis disrupted in a person who is anemic?

Anemia disrupts homeostasis by decreasing the amount of oxygen your blood can carry. This decreased capacity can lead to fatigue and slower thinking.

Can parasites cause anemia in dogs?

== Answer == Yes parasites that are left untreated can certainly cause anemia in dogs. Dogs can get many human diseases such a diabetes, heart problems, arthritis, types of cancer and seizures. People with pets should have their pet have a good physical ever year and all the necessary shots.

In macrocytic anemia why the MCH is in normal range?

well, that's what i understand and am not an expert

there is nuclear cytoplasmic dissociation in which the immaturity is for the nucleus only but the cytoplasmic organelle are mature

folate is needed in production of thymine (purely DNA) but to get RNA you dont need it uracil)

so you will have mature cytoplasm in which HG is normally formed (not arrested)

MCHC is normal but MCH is elevated coz MCH is dividing the HG by RBC count which will give you the HG per cell,, which is higher simply because you have a larger space (big cell) but MCHC is not elevated (not hyperchromic)

hope it helped

CAN LISINOPRIL BE TAKEN WITH ANEMIA?

We know nothing of your medical history or condition. Ask your doctor.

What is the relation between pernicious anemia and megaloplastic anemia?

the two terms are more or less interchangeable but they are not exactly the same.

Pernicious anaemia refers specifically to a condition where B12 fails to absorb in the gut: intrinsic factor is necessary for this absorption and is secreted by gastric pareital cells. Failure to secrete this substance can be due to atrophy of the cells, their absence due to total or partial gasrectomy or from circulating autoimmune pareital cell antibodies. There are other causes of failure to absorb B12 such as Blind Loop Syndrome but this is not known as Pernicious Anaemia. Nor is folate deficiency however all these conditions are known as megaloblastic anaemias. The diagnostic features of all this group of anaemias include megaloblasts in the bone marrow and are morphologically indistinguishable whether caused by B12 deficiency (for whatever reason) or folate deficiency.

As far as I know, the two terms are more or less interchangeable. Both apply to a kind of anaemia caused by a deficiency of either B vitamins B12 or B9 (folic acid). It is characterised by big red blood cells i.e. a raised MCV (mean cell volume). If one looks at the developing red cells in the bone marrow they have a characteristic appearance and are known as MEGALOBLASTS. Poor diet can be the cause of folic acid (folate) deficiency but the most likely cause of B12 deficiency is a failure to absorb the vitamin due to a problem in the gut. Both are easily treated. Injections of vitamin B12 will cause a remarkably quick recovery. Oral folate supplements will remedy this deficiency quickly too.

Explain why vascular occlusions are common in patient with sickle cell anemia?

RBCs contain HbS and with oxygen are flexible discs. When O2 is low, RBCs sickle or become elongated and rigid. As that blood circulates the body may have decreased oxygen levels. The RBCs (or erythrocytes) are unable to pass easily through small arteries so the cell membrane is damaged and tissue damage and multiple infarctions occur.

Is sickle cell anemia disease a disability?

yes because you wont have enough red blood cells in your body, and eventually they will start to decrease more... even taking a few steps will cause you to fall or even faint... you can no longer walk on your own or make any movements because you will feel like you are about to pass out. Therefore you will need a wheelchair and somone next to you helping you every day. That is considered a disability

Can low hemoglobin cause muscle pain?

Yes, low hemoglobin can cause muscle pain. Hemoglobin is a protein and is attached to red blood cells. Its job is to carry oxygen to the body's tissues. Without oxygen the tissues (including muscle) experience ischemia which is painful. Ischemia is what causes the pain a person has when they have a heart attack, for instance. So if a person's red blood cells are not carrying oxygen (because their hemoglobin levels are low enough), they would have muscle pain.
