Sickle-cell anemia, which can cause blood cells to clump up and block blood vessels, can also lead to stroke. Stroke is the second leading cause of death in people under 20 with sickle-cell anemia. [52] Air pollution may also increase stroke risk. [53]
Anaemia may develop in several ways: iron malabsorption may cause iron deficiency anaemia, and folic acid and vitamin B 12 malabsorption may give rise to megaloblastic anaemia. Calcium and vitamin D malabsorption (and compensatory secondary hyperparathyroidism ) may cause osteopenia (decreased mineral content of the bone) or osteoporosis (bone ...
Hematologic diseases: chronic hemolytic anemia (including sickle cell disease) Systemic diseases: sarcoidosis, pulmonary Langerhans cell histiocytosis: lymphangioleiomyomatosis, neurofibromatosis, vasculitis; Metabolic disorders: glycogen storage disease, Gaucher disease, thyroid diseases
Since folate deficiency limits cell division, erythropoiesis (production of red blood cells) is hindered. This leads to megaloblastic anemia, which is characterized by large, immature red blood cells. This pathology results from persistently thwarted attempts at normal DNA replication, DNA repair, and cell division, and produces abnormally ...
It may be caused by an underlying disease, such as sickle cell anemia, cystic fibrosis, rheumatoid arthritis. Cancer or functional disorders such as migraines, fibromyalgia, and complex regional pain could also cause chronic pain in children. [95]
The disease affects how oxygen is delivered to the red blood cells and is often diagnosed at a young age, discovered through a diagnosis of anemia. In a 2019 study on racial discrimination and dental health in the U.S. the authors found that the "emotional impact of racial discrimination" results in fewer visits to a dentist. [49]
t. e. Hypertension, also known as high blood pressure, is a long-term medical condition in which the blood pressure in the arteries is persistently elevated. [11] High blood pressure usually does not cause symptoms itself. [1] It is, however, a major risk factor for stroke, coronary artery disease, heart failure, atrial fibrillation, peripheral ...
[114] [115] The second initiative, focused on Sickle-cell disease (SCD), resulted in passage of the National Sickle Cell Anemia Control Act in May 1972. Long ignored, the lifting of SCD from obscurity to high visibility reflected the changing dynamics of electoral politics and race relations in America during the early 1970s.
