Understanding these tradeoffs is the secret sauce behind a calm, confident experience. When you know what's at stake, you can weigh the lifesaving insight a bronchoscopy offers against the shortterm irritations that might follow.
Common Side Effects
Throat Numbness & Soreness
What you'll feel
After the anesthetic spray, your throat can feel like you've just swallowed a handful of ice. The numbness usually fades after 12hours, but a mild soreness can linger for a day.
Homecare tip
Try soft foods, warm saltwater gargles, and lozenges. One of my friends, John, swore he'd never eat soup againuntil he realized a simple honeylemon tea was the perfect soothing remedy.
SedationRelated Drowsiness
What you'll feel
The sedation makes you feel "out of it" for 612hours. Think of it as the gentle wave you get after a lazy Sunday brunch, only a bit stronger.
Homecare tip
Arrange a driver, keep water nearby, and skip the espresso until the fog lifts. Your body will thank you for the extra rest.
Transient Low Oxygen (Hypoxemia)
What you'll feel
During the scope's insertion, oxygen levels can dip a little. Most patients notice a brief "tight chest" feeling that clears once the doctor finishes.
When to call
If your pulseoximeter (if you have one at home) reads below 90% for more than five minutes, or if you feel dizzy, give your doctor a call right away.
Cough & Mild Chest Discomfort
What you'll feel
The bronchoscope irritates the airway, so a cough that lasts 13days is common. Some describe it as a "tickle that won't quit."
Homecare tip
Honeybased cough lozenges and a humidifier can calm the irritation. A gentle puff of steam (think shower) also works wonders.
Rare but Serious Complications
What you need to know
Bleeding, pneumothorax (a tiny lung "pop"), and infection happen in less than 1% of cases. They're rare, but they're real, so stay alert for redflag symptoms.
Redflag checklist
- Heavy or persistent bleeding from the mouth or nose
- Sharp chest pain that worsens with breathing
- Shortness of breath or rapid breathing
- Fever over 38C (100.4F) lasting more than 24hours
- Sudden worsening of cough with blood-tinged sputum
PreProcedure Prep
Medication Checklist
What to do
Stop blood thinners, aspirin, and NSAIDs as your doctor advisesusually 48hours before the test. Write down every medication you take; it helps the team avoid surprises.
Fasting & Hydration
What to do
Nothing solid after midnight. A small sip of water is fine once the numbing spray wears off. Staying hydrated before the fast helps keep your throat moist.
Planning Support
What to do
Ask a family member or friend to stay with you for the first night. Prepare softfood snacks (yogurt, applesauce) and keep a water bottle within reach.
AfterCare Tips
Immediate PostProcedure Steps
Firsthour guide
Keep your head elevated, breathe slowly, and wait until the numbness fades before swallowing food. Light activity like a short walk around the house is finebut no heavy lifting.
Managing Common Side Effects
Homecare checklist
- Gargle warm salt water three times a day
- Use overthecounter pain relievers (acetaminophen) if sore throat persists
- Stay hydratedaim for 810 glasses of water in 24hours
- Apply a humidifier in your bedroom at night
- Rest and avoid driving for at least 24hours after sedation
When to Call Your Doctor
Redflag symptoms (again)
Heavy bleeding, sudden chest pain, low oxygen reading, fever, or worsening cough with bloodall require immediate medical attention.

| Day | Typical Feelings | Suggested Activities |
|---|---|---|
| 02 | Throat soreness, mild drowsiness | Rest, soft foods, light walking |
| 37 | Most side effects fade | Gradual return to normal diet, short errands |
