Sickle cell disease SCD is a group of inherited red blood cell disorders. If you have SCD, there is a problem with your hemoglobin. Hemoglobin is a protein in red blood cells that carries oxygen throughout the body. With SCD, the hemoglobin forms into stiff rods within the red blood cells. This changes the shape of the red blood cells. The cells are supposed to be disc-shaped, but this changes them into a crescent, or sickle, shape.

The sickle-shaped cells are not flexible and cannot change shape easily. Many of them burst apart as they move through your blood vessels. The sickle cells usually only last 10 to 20 days, instead of the normal 90 to days.

Your body may have trouble making enough new cells to replace the ones that you lost. Because of this, you may not have enough red blood cells.

This is a condition called anemia , and it can make you feel tired. The sickle-shaped cells can also stick to vessel walls, causing a blockage that slows or stops the flow of blood. When this happens, oxygen can't reach nearby tissues. The lack of oxygen can cause attacks of sudden, severe pain, called pain crises. These attacks can occur without warning.

If you get one, you might need to go to the hospital for treatment. The cause of SCD is a defective gene, called a sickle cell gene. People with the disease are born with two sickle cell genes, one from each parent. If you are born with one sickle cell gene, it's called sickle cell trait. People with sickle cell trait are generally healthy, but they can pass the defective gene on to their children.

People with SCD start to have signs of the disease during the first year of life, usually around 5 months of age. Early symptoms of SCD may include. The effects of SCD vary from person to person and can change over time. Most of the signs and symptoms of SCD are related to complications of the disease. They may include severe pain, anemia, organ damage, and infections. A blood test can show if you have SCD or sickle cell trait.

All states now test newborns as part of their screening programs, so treatment can begin early. People who are thinking about having children can have the test to find out how likely it is that their children will have SCD.

Doctors can also diagnose SCD before a baby is born. That test uses a sample of amniotic fluid the liquid in the sac surrounding the baby or tissue taken from the placenta the organ that brings oxygen and nutrients to the baby. The only cure for SCD is bone marrow or stem cell transplantation. Because these transplants are risky and can have serious side effects, they are usually only used in children with severe SCD. For the transplant to work, the bone marrow must be a close match.

Usually, the best donor is a brother or sister. To stay as healthy as possible, make sure that you get regular medical care, live a healthy lifestyle, and avoid situations that may set off a pain crisis. Resources Find an Expert.

Nutritional-deficiency anemia is a common issue that can happen if the body does not absorb enough of certain nutrients. It can result from an imbalanced diet or certain health conditions or treatments. Nutritional deficiencies can lead to a low red blood cell count, low levels of hemoglobin in these cells, or red blood cells that do not function as they should. Anemia is a term for these issues. Iron-deficiency anemia is the most common type, but low levels of folate or vitamin B can also cause the condition, and a low vitamin C intake can contribute to it.

Глаза Сьюзан сузились. Она терпеть не могла, когда он называл ее Сью. Вообще-то она ничего не имела против этого имени, но Хейл был единственным, кто его использовал, и это было ей неприятно.

Джабба открыл рот, готовый что-то сказать, но тут его буквально парализовал душераздирающий крик. Все повернули головы к Сьюзан Флетчер, которая выпрямилась и поднялась со стула.
