Introduction
Some people with severe
chronic obstructive pulmonary disease (COPD)—especially those with
emphysema—may be underweight and malnourished.
- People with COPD often lose weight. When you
lose weight, you lose muscle mass, including the muscles that help you breathe.
This may make breathing more difficult.
- Some people
with COPD weigh too little for good health. People who are very
underweight, especially those with emphysema, are at higher risk of death than
are people with COPD who have a normal weight.1
- To avoid losing weight and muscle mass, you
generally need to eat more foods containing fat and protein. Because eating too
much fat and targeting certain nutrients (such as protein) may have health
risks, always consult with your doctor or a
registered dietitian before eating more of these foods
to gain weight.
Although
the reasons for weight and muscle loss in COPD are not completely understood,
experts believe that it happens because of a combination of things. These
include:
- Using more energy overall (perhaps due to the
increased energy required to breathe).
- Using more energy during
physical activity.
- Eating less because of shortness of breath.
Shortness of breath may make it difficult to shop for, prepare, and eat
foods.
- Using oral
corticosteroids, which increase the breakdown of
muscle tissue in the body.
- Exercising some muscles less, which can cause them to weaken.
- Increased inflammation caused by COPD.
- Hormonal imbalances.
- Having less interest in food. People who have COPD may be
depressed (causing a lack of interest in eating) or
may be taking medicines that reduce appetite.
- The possibility that
COPD may reduce oxygen levels in the blood. This can prevent your body from
using food properly.
Poor eating habits and nutrition also can contribute to weight
loss. For older adults, the cost of food and being isolated from others may
play a role in poor eating habits.

Continue to Why?
Weight loss is
a concern in COPD because as you lose weight, you lose muscle mass. Muscle loss
may result in your feeling weaker. And muscle loss makes it harder to breathe (the
muscles that help you breathe also weaken). Weakness can also lead to a greater
chance of infections, such as
pneumonia.
Some people with
COPD weigh too little for good health. People who are very underweight,
especially those with emphysema, are at higher risk of death than are people
with COPD who have a normal weight.1

difficult.

including the muscles that help you breathe. This can result in more difficulty
breathing.

Continue to How?
If you are
beginning to lose weight and muscle mass, you probably need to eat more protein
and get more calories. This generally means eating more foods containing fat
and protein. Because eating too much fat and targeting certain nutrients (such
as protein) may have health risks, always consult with your doctor or a
registered dietitian before eating more of these foods
to gain weight.
High-calorie, nutritious snacks
Foods that can
help you add nutritious calories to your diet include:
- Ice
cream.
- Pudding.
- Cheese.
- Granola
bars.
- Custard.
- Nachos with
cheese.
- Eggs.
- Crackers with peanut
butter.
- Bagels with peanut butter or cream
cheese.
- Cereal with half and half.
- Popcorn with
margarine and Parmesan cheese.
- High-calorie nutritional
supplements, such as nutrition shakes.
Adding calories to a meal or snack
Adding the
following foods to meals or snacks can help you add calories and protein to
your diet.
- Add an egg or egg yolk to meat loaf, macaroni
and cheese, or similar foods. Be sure to cook the food after adding the
egg.
- Add powdered milk to creamed soups, scrambled eggs, pudding,
potatoes, yogurt, and casseroles.
- Add cheese to sandwiches,
crackers, casseroles, soups, toast, and pasta.
- Add an extra
tablespoon of vegetable oil or olive oil, mayonnaise, butter, margarine, or
sour cream to sandwiches, bread, casseroles, soups, cooked cereals, pasta,
potatoes, rice, or vegetables.
- Grind up some nuts and sprinkle the
dust on puddings, gravy, mashed potatoes, casseroles, salads, and
yogurt.
Adding protein to your diet
Milk, milk products,
and meats are high in protein. Try to eat more of these foods, or:
- Add skim milk powder to milk, cold cereals,
scrambled eggs, soups, and ground meat.
- Add cheese or peanut butter
to snacks.
- Choose desserts that use eggs, such as sponge cake, egg
custard, and rice pudding.
- Use nutritional supplements high in
protein, such as nutrition shakes.

Continue to Where?
If you have COPD and are
worried about losing weight, see your doctor or a registered dietitian. He or
she can help you plan a healthy, high-calorie and high-protein diet.
If you are eating more calories but are continuing to lose weight, see
your doctor.
People with COPD often have little interest in food
or difficulty eating because of shortness of breath. For tips on eating
