Aplastic anemia is not contagious and has a minor hereditary factor, meaning that if a family member has aplastic anemia, it is generally not inherited by the next generation. The cause of aplastic anemia is still unclear, but possible reasons include: 1. Damage to hematopoietic stem cells. After the hematopoietic stem cells are damaged, it leads to limited stem cell proliferation and reduced hematopoiesis. 2. Damage to the hematopoietic microenvironment. Damage to the hematopoietic microenvironment can lead to changes that disrupt the regeneration of hematopoietic stem cells. 3. Immune factors. Immune factors can cause immune damage, directly damaging hematopoietic stem cells, thereby causing bone marrow regeneration disorders.

Are the liver and kidney functions normal in patients with aplastic anemia?

Patients with aplastic anemia generally have normal liver and kidney functions. However, in certain special circumstances, abnormalities in liver and kidney functions may occur, including: Firstly, the routine treatment for aplastic anemia mainly includes the immunosuppressant cyclosporine and the hematopoietic stimulant androgens. The primary side effect of cyclosporine is renal toxicity. Therefore, during the use of cyclosporine, it is necessary to monitor the concentration of cyclosporine; excessive levels can lead to renal dysfunction. Androgens, including stanozolol and danazol, primarily cause hepatic toxicity; hence, it is necessary to monitor liver and kidney functions during treatment of aplastic anemia. The second factor that may cause liver and kidney function abnormalities is severe anemia. Long-term severe anemia can lead to tissue ischemia and hypoxia in the liver or kidneys, and if prolonged, it can cause abnormalities in liver and kidney functions. (Medication use should be carried out under the guidance of a physician.)

What to eat for aplastic anemia

Patients with aplastic anemia should eat light, easily digestible foods, and soft diet, avoiding too hard foods, and foods with spines or bones to prevent these foods from scratching the mucous membrane of the digestive tract and causing gastrointestinal bleeding. Additionally, patients with aplastic anemia must also take medications to control the progression of the disease, the related medications mainly include immunosuppressants, such as cyclosporine, as well as hematopoietic stimulants and traditional Chinese medicine formulations. Hematopoietic drugs include androgens, such as danazol and stanozolol, etc., and traditional Chinese medicines include compound alumite pills, rejuvenating blood tablets, etc. (Please use specific medications under the guidance of a doctor, and do not self-medicate.)

Does aplastic anemia cause fever?

Aplastic anemia itself does not cause fever in patients; however, individuals with aplastic anemia experience a decrease in all blood cells, including white blood cells, red blood cells, and platelets. A significant reduction in white blood cells, such as in a state of neutropenia, can lower a patient's resistance to infections, which makes it easy for secondary infections to occur and thus induce fever. Furthermore, in cases of severe anemia, severe aplastic anemia can also lead to the occurrence of low-grade fever in patients. On the other hand, a reduction in platelets generally does not cause fever. Therefore, when a patient with aplastic anemia has a fever, it is important to determine the cause of the fever.

Aplastic anemia is caused by how?

Aplastic anemia currently still has an uncertain etiology. However, clinical observations have suggested that chemotherapy drugs, viral infections, and radiation exposure might be related to the occurrence and development of aplastic anemia. Regardless of the cause, these factors all involve abnormalities in immune function. Abnormal immune function leads to the occurrence and development of aplastic anemia. Therefore, immunosuppressive therapy is often effective for patients with aplastic anemia in clinical settings. (Medication use should be conducted under the guidance of a professional doctor.)

Does aplastic anemia easily cause oral ulcers?

Patients with aplastic anemia are more prone to oral ulcers. Aplastic anemia is a type of bone marrow failure syndrome, where there is a decrease in white blood cells, red blood cells, and platelets in the peripheral blood to various extents. Long-term anemia can lead to mucosal ischemia and hypoxia. The reduction in white blood cells weakens the mucosal barrier's protective function, making it susceptible to bacterial invasion and thus prone to oral ulcers. Additionally, patients with anemia often have poor diets over long periods, leading to a deficiency in various vitamins, which is another reason why they are prone to oral ulcers. If symptoms like joint pain are present along with oral ulcers, further rheumatological and immunological tests should be conducted to rule out rheumatic and immune system diseases.
