Treating anaemia can boost energy

3 July 2010

Anaemia is not a normal part of ageing, yet it's fairly common in older adults and causes frailness, weakness and increased risk of falls. According to Mayo Clinic Women's HealthSource, more than one in 10 older adults has anaemia. Twenty percent of women are anaemic by age 85.

The June issue of the newsletter provides an overview of anaemia, including symptoms, causes, diagnostic tests and treatment options.

Anaemia occurs when the number of red blood cells in the blood drop below normal, or the red blood cells don't contain enough haemoglobin, the iron-rich protein that gives blood its red colour. The classic anaemia symptoms are pale skin, fatigue and shortness of breath or weakness. In older adults, initial symptoms may be fainting spells, chest pain or confusion. Because many tissues and organs can be affected, other symptoms are possible, too, including dizziness, cold hands and feet, headaches and a fast heartbeat. Highlights from the report include:

Most common cause

Iron deficiency anaemia, caused by blood loss, is the most common type of anaemia. Chronic bleeding in small amounts over a long time depletes the body of iron. In older adults, blood loss usually stems from intestinal diseases, such as ulcers, colon polyps, diverticulitis or cancer. Aspirin or nonsteroidal anti-inflammatory drugs such as ibuprofen can also cause bleeding.

Other causes

Vitamin B-12 and folate are needed to produce healthy blood cells. When these nutrients are missing from the diet, or the body can't absorb B-12 from food, anaemia can result. Some long-term illness can cause anaemia, too. Examples include rheumatoid arthritis, HIV/AIDS, cancer, cirrhosis and other forms of liver disease.

Treatment

Anaemia isn't a disease, but rather a sign of an underlying problem, so treatment is tailored to the cause. For those with iron deficiency anaemia, eating iron-rich foods can help. Examples include fortified cereals and breads, red meat, peas, beans, lentils, eggs, spinach and other dark green leafy vegetables, dried fruits (raisins, apricots and peaches), tofu, chicken and pork. Supplements, when recommended by a doctor, may also be helpful. Severe anaemia may require transfusions, medication to prevent the body's immune system from destroying its own red blood cells, or a synthetic version of the hormone erythropoietin to stimulate the bone marrow to make more red blood cells.

Even mild anaemia can take a toll on energy levels and quality of life. When anaemia is suspected, consult a doctor about a complete blood count to check for the condition. Just a small increase in blood count numbers can boost energy and help maintain an active life.
