What Should Seniors Know About Anemia?
Anemia, a condition where blood lacks adequate healthy red blood cells, is common in seniors and often causes symptoms attributed to aging. Understanding anemia helps seniors recognize symptoms and access treatment that can dramatically improve energy and wellbeing.
Understanding Anemia
Red blood cells carry oxygen throughout the body. When red blood cell count or hemoglobin is low, tissues do not receive adequate oxygen. This oxygen deficit causes the symptoms of anemia.
Anemia is not a disease itself but a sign of an underlying condition. Finding and treating the cause is as important as treating the anemia itself. The cause determines appropriate treatment.
Why Anemia Affects Seniors
Anemia becomes more common with age, affecting about 10 percent of people over 65 and higher percentages at older ages. Multiple factors contribute to this increased prevalence.
Chronic diseases common in seniors cause anemia. Kidney disease, inflammatory conditions, and cancer all affect red blood cell production. This anemia of chronic disease is common.
Nutritional deficiencies cause anemia. Iron deficiency from blood loss or poor absorption, B12 deficiency from decreased absorption with age, and folate deficiency all cause anemia in seniors.
Bone marrow function may decline with age. The marrow produces fewer red blood cells. Some bone marrow conditions become more common with age.
Symptoms
Fatigue is the most common symptom. Feeling tired, weak, and lacking energy affects daily function. Many seniors attribute this fatigue to aging when anemia is actually responsible.
Shortness of breath with exertion occurs because tissues are not getting enough oxygen. Activities that used to be easy become tiring. This symptom may be mistaken for heart or lung problems.
Other symptoms include pale skin, dizziness, cold hands and feet, headaches, and rapid heartbeat. Cognitive symptoms including difficulty concentrating may occur.
Diagnosis
Complete blood count detects anemia by measuring red blood cells and hemoglobin. Additional tests determine the type and cause of anemia.
Iron studies, B12 and folate levels, kidney function tests, and sometimes bone marrow evaluation help identify the underlying cause. Treatment depends on accurate diagnosis.
Treatment
Iron deficiency anemia is treated with iron supplementation. Iron tablets are commonly prescribed. Dietary iron increase helps. Finding and stopping blood loss is essential.
B12 deficiency requires B12 supplementation. Injections bypass absorption problems common in seniors. Once levels normalize, maintenance therapy continues.
Anemia of chronic disease improves when the underlying condition is treated. Erythropoietin injections may be used for kidney disease-related anemia.
Blood transfusions treat severe anemia or anemia not responding to other treatments. Transfusions provide immediate but temporary correction.
Impact of Treatment
Treating anemia often dramatically improves energy and quality of life. Symptoms attributed to inevitable aging may resolve. Do not assume fatigue is just aging without checking for anemia.
Getting Anemia Care
All Seniors Foundation encourages evaluation of fatigue and anemia symptoms. Treatable causes of tiredness should not be missed. Contact us if fatigue or other symptoms might indicate anemia.
