62.1 billion people in the world suffer from anemia, or 8.24% of the world's population.
The highest rate among children before school age is 4.47% and the lowest rate among men, where this percentage does not exceed 7.12%, according to the World Health Organization. the health.
WebMD provides a simple explanation of anemia and its symptoms, as well as how to prevent them, as follows:
What is anemia?
Anemia occurs when a person does not have enough strong, healthy red blood cells to carry oxygen throughout the body. Blood cells can also lack hemoglobin, a protein that gives blood its red color. It is common among women of childbearing age, the elderly, women of African or Latin American descent.
Symptoms of anemia
One of the most important symptoms is fatigue despite a good sleep or lack of energy for normal activities. Anemia may be the underlying cause of memory problems or mood swings.
Symptoms range from mild to life-threatening and may include any of the following symptoms:
• weakness
• fear of heights
• dullness of the skin
• headache
• numbness or coldness in the hands and feet
• Low body temperature
Causes of anemia
Anemia affects women and people with chronic diseases, such as kidney failure, which affects the body's ability to make red blood cells. A diet low in iron, folic acid or vitamin B12 also increases the risk of anemia. Some types of anemia are due to genetic causes:
1 – low amount of iron
Lack of attention to eat iron-rich foods leads to anemia. Gastrointestinal problems such as Crohn's disease, gastrointestinal illness or even stomach surgery can cause iron deficiency problems. Some foods and drugs inhibit the absorption of iron, such as:
• dairy products
• Other foods rich in calcium
• calcium supplementation
• antacids
• coffee
• tea
2 – lack of vitamins
The body needs both vitamin B12 and folic acid to make red blood cells, and their deficiency can sometimes lead to anemia. It can also prevent autoimmune disorders, or digestive problems, the absorption of a sufficient amount of vitamin B12.
3 – Anemia
Aplastic anemia is a rare condition in which the bone marrow does not produce enough blood cells to supply the body. It only affects 2 million people. This may be due to high doses of radiation, exposure to chemicals, viruses, or a natural immune disorder in which the immune system attacks the bone marrow. Some cases are inherited.
4. Bleeding
The loss of many red blood cells is a common cause of anemia. Heavy periods, ulcers, wounds or surgeries can lead to bleeding, leading to anemia.
5 – Mechanics of blood cells
Genetic disorders can affect the production of red blood cells in the body. Thalassemia causes the production of the smallest number of red blood cells in the body and affects the health of hemoglobin, which can be treated by blood transfusion or by other treatments.
6 – sickle cell disease
Sickle cell disease is a genetic disorder in which the body produces an abnormal form of hemoglobin, which causes red blood cells to pass to the round shape and the sickle. This form of sickle makes it difficult to enter the blood vessels, resulting in pain and injury to the body tissues.
Protection tips
Scientists recommend the importance of working to prevent the incidence of certain types of anemia through a healthy diet. Foods containing iron include lean red meat, liver, fish, lentils, beans, dark green vegetables and dried fruits. Foods containing vitamin B12 and folic acid, such as eggs, dairy products, spinach and bananas, are also recommended.
Vitamin C contained in citrus fruits, fruits and other vegetables also helps the body absorb iron.
Doctors warn of excessive iron intake without the advice of a doctor because iron levels in the body cause problems in the liver, heart and pancreas. Iron levels can be reduced by phlegm (blood sampling) or medications.
