It's not a disease, it is a hereditary disorder. Basically it is a problem with irregular red blood cell shape, which can cause pain in the arteries and veins, among other things.
Yes, that is the only way that your bodily cells can receive oxygen. There is no other way, which is why diseases of the blood (eg. sickle cell anaemia, anaemia) can cause sufferers to become immuno-compromised and fatigued. If your red blood cells aren't moving 'oxygen' around your body, you'll either be very sick or be dead.
Sickle cell anemia cause red blood cells to be shaped like sickles. malaria can't enter these cells which gives the person an immunity to malaria.
A sickled red blood cell will live for 10 to 20 days before it is destroyed. A normal red blood cell would have lived for about 120 days. This is the cause of the anaemia in sickle cell anaemia patients, who typically live for about 45 years.
There are many different antituberculosis drugs available. A lot of them do cause anaemia as a side effect, although some of them do not. Depending on how each drug works, the type of anaemia it causes varies. Some antituberculosis drugs that cause anaemia as a side effect are: * Cycloserine - megaloblastic anaemia * Isoniazid - haemolytic anaemia or aplastic anaemia * Pyrazinamide - sideroblastic anaemia * Rifampicin - haemolytic anaemia
Lack of Iron can cause a deficiency known as anaemia.
In haemoglobin, there are four polypeptide chains that make it's structure, 2 (A) chains and 2 (B) chains. Sickle-Cell Anemia is caused by a mutation the (B) chain that makes the haemoglobin molecules stick to each other and form fibres inside the red blood cell (RBC). Instead of a circular disc shaped RBC we now have a sickle shaped cell. This means transport of oxygen is very innefficient and the disease can cause death. However, in areas with a high malaria rate, heterozygous sickle-cell anaemics (with some sickle shaped AND normal RBCs) are naturally selected because the protozoan (what causes the disease) is unable to live inside the red blood cell due to the fibres formed from the mutation, the cells are more fragile and they have a shorter life span than normal RBCs. This means that people with heterozygous alleles for sickle-cell anaemia benefit against malaria and will survive to reproduce, which increases the allele frequency of the sickle-cell anaemia allele. Those with homozygous sickle-cell anaemia and those with homozygous normal haemoglobin are selected against as the first usually die of the sickle-cell anaemia, and the latter contract malaria. NB. Mutations are rare occurrences. It is even rarer for a mutation to give selective advantage. This mutation for sickle-cell anaemia did not happen to 'cure' or prevent malaria, it was a random occurrence that coincidentally gave a selective advantage against malaria.
Yes in sickl cell disease the white blood cell is

Yes anaemia can cause heart flutters (palpitations). The cause is usually due to the heart trying to compensate for low oxygen levels in the body. Anaemia is an abnormally low amount of haemoglobin in the blood, which is the part of blood which carries oxygen. Therefore, low haemoglobin levels lead to low oxygen levels. In response, the heart will often try to increase the amount of blood pumped around the body, to meet the body's demand for oxygen by beating faster. This can cause a high heart rate which can lead to palpitations or heart flutters.
No
Diarrhoea and bleeding from colitis does cause severe anaemia, sometimes requiring blood transfusion before surgery
