Managing weight changes with PF
What is a healthy weight?
For people with PF, this can be complex. Being too overweight may put pressure on the lungs. However, a low weight can be linked to poorer health. Many people with PF lose weight unintentionally as their condition progresses. Because of this, having a higher weight to begin with may sometimes be beneficial.
A healthy weight for you depends on your unique situation. You may want to discuss your weight with your medical team.
If you're losing weight unintentionally
PF can increase the amount of energy your body needs. Because of this, some people may burn more calories even while resting. If you're losing weight unintentionally, speak to your medical team. They may recommend that you change your diet to eat more calories and nutrients. See our fortification information for ideas on how to add energy-dense foods to your diet.
Your healthcare team may also suggest practical ideas to help you eat more calories and nutrients. This could include things such as:
- eating soft, easy-to-chew foods if breathlessness makes eating difficult. You may want to try adding sauces such as gravy or custard to help soften your food.
- drinking fluids with and between meals rather than before. This may help to avoid getting full with fluid rather than food.
- eating four to six small meals throughout the day, if large meals feel overwhelming.
- drinking nutritional supplement drinks (such as Complan or Meritene), which can help you add extra calories without the effort of eating. You can buy these from supermarkets and pharmacies, or you may be able to get a prescription for them.
If you need to lose weight for lung health
Being too overweight may put extra pressure on the lungs, making it harder to breathe. If you think you might benefit from losing weight, speak to your healthcare team.
If you are changing what you eat, it’s important to know about muscle. Some research shows that people with more muscle may manage better with lung conditions. Muscle also adds to your body weight. This means that losing weight does not always mean better health.
Food helps maintain muscle, but muscles also need to be used to stay strong. You might hear this described as ‘use it or lose it’. Keeping active, even gentle movement, helps keep your muscles working, including the ones that help you to breathe. Your healthcare team can help you decide what’s right for you, and you can read more about exercise and breathing techniques on our website.
