After an upper endoscopy, you should wait 30 to 45 minutes before eating or drinking anything. The throat spray or sedation used during the procedure temporarily affects your ability to swallow, and eating too soon raises the risk of choking. Once you can swallow comfortably, start with clear liquids and work your way up to soft foods over the next 24 hours.
The First Hour: Liquids Only
Your throat will likely feel numb or scratchy right after the procedure. Once that numbness fades (usually within 30 to 45 minutes), take small sips of water first to test your swallow reflex. If water goes down easily, you can move on to other clear liquids: tea, broth, sports drinks, popsicles, or diluted juice. Room-temperature or cool liquids tend to feel best. Very hot or very cold drinks can irritate the lining of your throat and stomach, which are already mildly inflamed from the scope.
Since you fasted before the procedure and likely received sedation, your body needs fluids. Sip steadily through the first few hours rather than gulping large amounts at once. A sports drink or broth can help replenish electrolytes lost during fasting.
Soft Foods for the First 24 Hours
Once liquids feel comfortable, usually within a couple of hours, you can introduce soft foods. The goal is to avoid anything that requires heavy chewing or could scratch or irritate your throat and upper digestive tract. Good options include:
- Eggs: Soft scrambled or poached. Avoid frying them in heavy oil.
- Soups and broths: Cream soups, chicken broth, or vegetable soups with soft-cooked carrots, potatoes (without skins), peas, or squash.
- Fruit: Applesauce, banana, canned fruit cups, or avocado.
- Dairy: Yogurt, cottage cheese, soft cheeses like ricotta or brie, pudding, or low-fat ice cream if cold foods don’t bother you.
- Starches: Cooked oatmeal or cream of wheat (without nuts or seeds), bread softened in soup, or plain crackers.
- Protein: Ground or shredded chicken, turkey, or pork. Boneless white fish like cod or tilapia works well too.
Think of textures you could comfortably swallow without much chewing. If you need to cut it with a knife, it’s probably too firm for the first day.
What to Avoid
For at least 24 hours after your endoscopy, skip anything that could irritate your digestive tract while it recovers from the procedure. That includes spicy foods, acidic foods like tomato sauce and citrus, raw crunchy vegetables, nuts, seeds, chips, and tough or chewy meats. Carbonated drinks can cause bloating and gas, which may worsen any abdominal discomfort you’re already feeling from the air pumped into your stomach during the procedure.
Alcohol is off limits for at least 24 hours, both because it irritates the stomach lining and because it interacts poorly with residual sedation. Stick with decaffeinated coffee or tea if you need a warm drink. Caffeine can increase stomach acid production, which you don’t want while your digestive tract is recovering.
If You Had a Biopsy
Many endoscopies involve taking a small tissue sample for testing. If your doctor took a biopsy, the same soft-food guidelines apply, but you may want to be extra cautious for a full 48 hours. The biopsy site is essentially a tiny wound inside your digestive tract. Rough, acidic, or very hot foods can slow healing or cause discomfort at the site. Your doctor’s discharge instructions will specify any additional restrictions based on what was done during your procedure.
Dealing With a Sore Throat
A mild sore throat is one of the most common side effects and usually lasts one to two days. Gargling with lightly salted warm water helps, and sucking on hard candy or throat lozenges can soothe the irritation between meals. Cool, smooth foods like yogurt, pudding, and ice cream also feel good on a raw throat. Avoid dry or scratchy foods like toast, crackers, or granola until the soreness passes.
Returning to Normal Eating
Most people can eat normally within 24 hours of a straightforward endoscopy. Start by gradually reintroducing firmer foods at your next meal after the soft-food period. If something causes discomfort, back off and give it another meal or two. By the second day, your diet should be back to normal unless your doctor has given you specific instructions based on findings from the procedure.
Pay attention to how your body responds. Mild bloating, a gassy feeling, or slight nausea in the first few hours are normal and usually resolve on their own. Persistent or severe chest pain, difficulty swallowing that doesn’t improve, fever, or vomiting are not normal and warrant a call to your medical team.
