Chronic Obstructive Pulmonary Disease (COPD) and Restrictive Pulmonary Disease (RPD)

Our lungs are continuously exposed to airborne bacteria, viruses and allergens which can cause lung disorders. Most of these disorders do not affect our air supply. However, Chronic Bronchitis and emphysema is where there is persistent disruption of air flow into and out of lungs causing respiratory insufficiency. Emphysema is a disease where the alveoli (small air sacs) in the lungs are damaged. Chronic bronchitis is caused by bacterial infection in which the mucous membranes of the bronchi are affected causing chronic cough. COPD patients tend to suffer from emphysema, chronic bronchitis and obstructed airflow to the lungs. 

Some characteristics changes on Body Composition in COPD and RPD


Monitoring Body Composition

Due to the daily inactivity if this group of patients and the increase energy requirement due to breathing difficulty COPD and RPD patients tend to have an imbalance between food intake and energy requirements. Loss of body weight could occur in some undernourished patients or in some cases loss of Fat Free Mass (FFM). COPD patient’s loss Fat Free Mass, bone mineral and muscle wasting is common.

The results from these Body Composition measurements can be used to design effective nutrition programs for patients. ICW/ECW ratio can change in this group of patients following surgery with progressive increase after surgery.

Assessing body composition in this group of people is important in case where Fat Free Mass is lost as a result of malnutrition and or Fat mass which may increase and could be undetected as no change in body weight is noticed.

The routine use of Maltron Analysers as screening tool could help identify these diseases
