Pernicious Anemia: Causes, Symptoms, and Treatment
This paper provides an accessible overview of pernicious anemia, a blood disorder distinct from classic anemia in its severity and consequences. The author — who has lived with the condition for over a decade — explains how an inherited or acquired deficiency in a stomach-produced chemical prevents the body from absorbing vitamin B12, impairing red blood cell formation. The paper covers the wide range of symptoms, from fatigue and pale complexion to serious neurological impairments such as memory loss and loss of coordination. It also outlines diagnostic procedures and treatment options, chiefly monthly vitamin B12 injections, and emphasizes the critical importance of early diagnosis in preventing irreversible neurological damage.

What makes this paper effective
- The author uses a personal narrative frame to ground a medical topic in real human experience, making the clinical content immediately relatable without sacrificing accuracy.
- The paper consistently distinguishes pernicious anemia from classic anemia, giving readers a clear comparative framework that reinforces why the condition is uniquely serious.
- Technical symptoms and terminology (e.g., Babinski's reflex, bone marrow examination) are introduced with brief explanatory context, keeping the paper accessible to a general audience.
Key academic technique demonstrated
The paper demonstrates the technique of using personal testimony to establish relevance before transitioning into evidence-based exposition. By opening with the author's own diagnosis and closing by returning to it, the essay creates a coherent narrative arc that holds together what could otherwise read as a list of medical facts. This structure — personal stakes, objective information, call to awareness — is an effective model for health-topic writing aimed at a general audience.
Structure breakdown
The paper is organized into five logical sections: an introductory personal anecdote establishing stakes; a definition of the disorder and its causes; a detailed account of symptoms; an explanation of diagnosis and treatment; and a conclusion returning to the author's experience to underscore the importance of early detection. This progression moves from the general to the specific and back to the personal, giving the paper both informational depth and emotional resonance.
Introduction: Living With Pernicious Anemia
Many people hate going to the doctor's office — especially when they know they will be receiving an injection. However, millions of people around the world, myself included, consider themselves very lucky to do just that, each and every month of their lives. For people with a disorder known as pernicious anemia, the doctor and her needle are the vital link between a healthy life and a life of absolute misery. Unlike classic anemia — the common form of the blood disorder that usually results in little more than fatigue — pernicious anemia can produce catastrophic changes in the body. Chief among these are severe neurological impairments that, in their most extreme form, can result in complete mental deterioration. For those who suffer from this disease caused by an inherited deficiency, or by some disruption or disorder in the stomach and gastrointestinal tract, the vitamin B12 injection is a lifesaver.
What Is Pernicious Anemia?
According to the Medline Plus Medical Encyclopedia, anemia is a blood disorder in which red blood cells are "not providing adequate oxygen to body tissues." In the case of pernicious anemia, however, the individual lacks an important chemical produced in the stomach that allows vitamin B12 — obtained from food — to be absorbed by the body. Because vitamin B12 is a necessary component for the formation of adequate numbers of red blood cells, a deficiency of the vitamin directly causes the anemia.
Interestingly, pernicious anemia is most often caused by heredity, but it can also result from physical changes in the body. These include stomach surgery or removal, disorders of the stomach lining, or, in rare cases, a simple lack of adequate nutrition. Those suffering from malnutrition and famine are at elevated risk for developing this form of anemia.
Symptoms and Complications
Although the symptoms of classic anemia may include fatigue or low red blood cell counts detectable in blood tests, it can take years before someone with classic anemia notices anything amiss. The symptoms of pernicious anemia, by contrast, are more numerous, severe, and wide-ranging. The lasting effects of leaving the disorder untreated far surpass the damage that classic anemia can cause.
Neurological symptoms can include clumsiness, an unsteady gait, loss or reduction of the sense of smell, difficulty with tongue control, and a positive Babinski's reflex — a foot reflex that, after the age of two, is a recognized sign of neurological problems. In severe cases, the condition may progress to changes in memory or reasoning, and even outright mental deterioration. Physical symptoms may also be present, including shortness of breath, fatigue, pale complexion, and a rapid heart rate — all reflecting a lack of oxygen being delivered by the red blood cells — as well as loss of appetite, diarrhea, and numbness of the extremities.
