Does COPD Cause Weight Loss [Medical Experts Explained]
Some people suffering from severe chronic obstructive pulmonary disease (COPD) may experience being underweight and malnourished as their situation worsens. When your lungs are not functioning well as they should, your body needs to work harder to respire.
Remember that when you lose weight, you lose muscle mass — including those responsible for breathing. Your partially blocked airways and damaged lungs make it a struggle to let air in and out. However, people with COPD may take various measures to prevent weight loss.
If the question “does COPD cause weight loss?” has been spinning in your mind for quite some time, you have reached the perfect site. Scroll through this article to discover more about the relationship between COPD and weight loss.
Metabolic Rate In Chronic Obstructive Pulmonary Disease Patients
In 2002, a study regarding the predictive value of weight change in COPD patients found that patients who did not gain weight were, on average, older, had a lower ratio between spontaneous energy input and energy expenditure, and higher degrees of indicators of systemic inflammation.
COPD patients often cannot produce enough energy because their oxygen delivery is impaired. Your physical activities are, therefore, restricted. Additionally, it manifests with several signs, such as muscle cramps and shortness of breath. Thus, people who use long-term oxygen have higher energy expenditure.
Chronic obstructive pulmonary disease COPD patients are known to have heightened metabolic rates due to impairment in their respiratory operation. Several studies claim that body mass index (BMI) with low fat-free mass index (FFMI) are major mortality risk factors.
Consequently, physicians have long advocated nutritional assistance as a valuable part of treating COPD patients with low BMI. Several dietary intervention studies have resulted in positive outcomes regarding pulmonary function, exercise capacity, or weight increase.
Meal Preparation With COPD Patients
Chronic obstructive pulmonary disease (COPD) causes a person to get too tired to prepare and eat meals. Knowing that regularly eating healthy foods is essential, having little appetite can cause severe health problems in the long run.
The following tips can help you get the necessary nutrition you need with ease.
- Choose meals that are quick to prepare.
- Eat with your family and friends.
- Eat in a relaxed environment.
- Try eating heavy meals early to get enough energy throughout the day.
- Try adding your favorite food to your meals.
Nutrition Recommendations For COPD Patients
Once you feel like you are losing weight, you should immediately visit your physician or dietician and ask what is happening. Their advice might include eating more protein and calories. In addition, ingesting small, frequent meals may be more manageable than eating big meals.
The United States Department of Agriculture provides easy and quick recipes to prepare most COPD patients’ meal planning. They advise individuals to focus on foods with high calories, protein, and fats.
1. Eat more high calorie foods
Patients who need to gain weight must add more calories to their diet proportionally. Some preparation tips to increase your calorie intake are as follows:
- Spread peanut butter in sandwiches or any of your preferred snacks.
- Drink smoothies with berries and nut butter.
- Mix a teaspoon of olive oil into your hot foods.
- Use honey to sweeten food and drinks.
- Eat walnuts, dried foods, almonds, and olives.
2. Eat foods with high protein
Sufficient protein intake helps build muscle mass and gain weight. Foods high in protein include nuts and seeds, cheese, tofu, eggs, meat, fish, poultry, and milk.
- Spread peanut butter on whole-grain snacks, sandwiches, toast, and cut-up apples.
- Add protein powder to milkshakes and smoothies.
- Add seeds or mixed nuts to cereal, cottage cheese, and yogurt.
3. Eat foods with high fat
Fats can help digest food and produce vitamins. You may talk to your doctor or dietician about including extra supplemental nutrition drinks for added vitamins, minerals, and calories.
- Cut-up apple with peanut butter, with mixed nuts and cinnamon on top
- Raw vegetables and hummus or ranch dressing
- Whole-grain crackers and nut butter
- Smoothie with fruit, yogurt, and nut butter
- Greek yogurt with berries and almond slices
- Cheese stick, hard-boiled egg, and mixed nuts
4. Eat small but frequent meals
As your COPD progresses, you will struggle to breathe when eating heavy meals. Eating nutritious foods frequently, even with smaller portions, is the best way to offset your condition.
However, when your COPD keeps weighing you down, or your weight is always below the desired level, you may need to visit your dietician and ask for a more suitable dietary meal.

What are the signs of COPD getting worse?

Coughing that lasts for several weeks demands a physician’s visit. They may require you to have a chest x-ray to ensure the diagnosis. It could be due to COPD or other heart problems.
If you increase the quantity of phlegm you produce and its color changes from clear to green or yellow, your COPD might worsen. The color change could be a signal on an infected lung.
Most people with weight loss COPD quickly get tired. Fatigue in Chronic obstructive pulmonary disease (COPD) can also be from inflammation that leaks throughout the patient’s body, thus, weakening the muscles.
Due to pulmonary hypertension, edema may cause the feet, legs, and ankles to swell. Such conditions include various health issues, such as high pressure on lung vessels, insufficient oxygen, and inflammation.
How do I gain weight with COPD?
Due to increased work of respiration, your COPD-infected body burns more calories. Aside from questioning, “why does COPD cause weight loss,” you should also ask about how to gain weight when diagnosed with COPD.
