Lungs and sickle cell are tied tighter than most people realize. People with sickle cell disease (SCD) face higher rates of breathing problems and sleep-related disorders than the general population — and those two things often feed each other. Catching trouble early protects everything downstream: your heart, your energy, your brain, your quality of life.
Here's a checklist to bring to your next clinic visit. Check off anything you've experienced — even occasionally — in the last year.
Daytime breathing:
- [ ] Coughing or wheezing
- [ ] Shortness of breath
- [ ] Difficulty breathing during exercise
- [ ] Chest pain
- [ ] Low oxygen levels (hypoxemia)
Sleep:
- [ ] Loud snoring
- [ ] Feeling sleepy or drowsy during the day
- [ ] Waking up feeling unrested
- [ ] Early morning headaches
- [ ] Trouble focusing or thinking clearly
SCD-related red flags:
- [ ] Acute chest syndrome (any history)
- [ ] Blood clots in the lungs (PE)
- [ ] Stroke
- [ ] Frequent pain crises
- [ ] Recurring, prolonged erections (priapism)
- [ ] Bedwetting after age 10
- [ ] Congestive heart failure
- [ ] Fainting or dizziness
Why these matter — together. Each item on its own can have multiple causes. But for someone with SCD, certain combinations point your provider toward specific tests:
- Sleep study (polysomnography) if the sleep checklist lights up — sleep apnea is more common and more dangerous in SCD.
- Pulmonary function tests (PFTs) to measure how well your lungs move air, if the daytime breathing list is checked.
- Echocardiogram if cardiac symptoms appear.
Acute chest syndrome (ACS) deserves its own paragraph. ACS is a life-threatening complication of SCD that combines fever, chest pain, low oxygen, and a new finding on chest X-ray. It can come on fast — sometimes after a regular pain crisis. If you're hospitalized for pain and you start having chest pain, fever, or shortness of breath, tell your team immediately. Treatment works best when started early.
Daily lung-friendly habits:
- Hydrate — 8 to 10 cups of water a day.
- Don't smoke. If you smoke, ask for help quitting; SCD makes the damage worse.
- Avoid secondhand smoke and high-pollution exposures.
- Keep up with vaccines — flu, pneumonia, COVID. SCD changes the math on infection risk.
- Use your incentive spirometer if your provider gave you one.
Bring the checklist to your appointment. Don't edit it down. The picture only helps when it's complete.
