Definition of Anemia.

Anaemia is a condition in which the number of red blood cells in  the  blood has decreased.

Anemia is a condition in which you do not have enough healthy red  blood cells to carry adequate oxygen to the tissues of the body, you  may  feel tired and weak if you have anemia.

Anaemia is a condition in which the number of red blood cells or their  capacity to carry oxygen is insufficient to meet physiological needs,  varying by age, sex, altitude, smoking, and status of pregnancy.

It’s not a diagnosis in itself because it has many different causes that  need  to be correctly identified to treat the condition successfully, it might also be the very next indicator of a serious underlying issue  such as an ulcer  of the stomach, an autoimmune condition or cancer.

Iron deficiency is thought to be the most common cause of anaemia  worldwide, although other conditions, such as deficiencies in folate,  vitamin B12 and vitamin A, chronic inflammation, parasite infections,  and inherited disorders, may all cause anaemia.

Anemia is the most common condition of blood in the United States.  it affects about 5.6% of the U.S. population, there is an increased risk of  anemia among women, young children, and people with chronic diseases. 

Important factors to remember are the following:

  • Some forms of anemia are hereditary and from the time of birth infants may be affected.
  • Women in childbirth are particularly susceptible to iron-deficiency anemia due to menstrual blood loss and increased demands for blood supply during pregnancy.
  • Older individuals may also be at increased risk of developing anemia due to poor diet and other medical conditions.

What Causes Anemia?

There are over 400 anemia types divided into three groups:

  • Anemia caused by blood loss.
  • Anemia caused by destruction of red blood cells.
  • Anemia caused by decreased or faulty red blood cell production.

What Are the Symptoms of Anemia?

Anemia symptoms vary depending on the type of anemia, the underlying cause, severity, and any underlying health issues such as hemorrhaging,  ulcers, menstrual issues, or cancer. first of all, specific symptoms of these  issues may be noticed.
