The First 24 Hours: Your Recovery Timeline

What to expect at each stage of your recovery from the moment you wake up.

First Hour

Recovery Room

You will rest in our recovery area for 20 to 30 minutes while sedation wears off. You may feel groggy, drowsy, or slightly confused — this is completely normal. Dr. Maher will speak with you before you leave to explain what he found. Because sedation can affect short-term memory, we also provide written discharge instructions and encourage your driver to be present for the discussion.

Hours 1 – 4

Getting Home and Settling In

Your driver will take you home. Once there, plan to rest for the remainder of the day. You may feel sleepy, and that is your body telling you to slow down. Light walking around your home is fine and can help relieve any bloating or gas.

Hours 4 – 12

Easing Back In

You should begin to feel more like yourself. Grogginess fades. Appetite returns. You can eat and drink normally unless Dr. Maher has given you specific dietary restrictions. Start with something light and easy to digest, then return to your usual meals as tolerated.

Hours 12 – 24

Almost Back to Normal

Most patients feel fully recovered by the next morning. You may resume your normal routine, return to work, and drive. If polyps were removed or biopsies were taken, continue to follow any additional instructions Dr. Maher provided at discharge.

What Is Normal After a GI Procedure

Minor aftereffects are expected and typically resolve within 24 to 48 hours.

After Colonoscopy

  • Mild bloating and gas (from air used during the exam)
  • Mild abdominal cramping
  • Small amount of blood with first bowel movement (if polyps were removed)
  • Irregular bowel habits for 1 to 3 days
  • Fatigue or grogginess for the rest of the day

After Upper Endoscopy (EGD)

  • Mild sore throat that fades within 24 to 48 hours
  • Slight bloating from air introduced during the exam
  • Mild nausea (uncommon and usually brief)
  • Drowsiness for the rest of the day

After Both Procedures Same Day

  • A combination of symptoms from both lists above
  • Slightly longer grogginess period is common
  • More gas and bloating than a single procedure
  • Rest, hydrate, and eat gently — all manageable

Activity Restrictions

A phased return to your normal routine over the first few days.

Day 0 — Procedure Day

Rest. Full restrictions in effect.

Do not drive, operate machinery, make legal or financial decisions, drink alcohol, or return to work. Sedation effects can impair judgment and coordination for up to 24 hours even if you feel fine. Arrange for help with childcare or household responsibilities if possible.

Day 1 — The Next Day

Return to most normal activities.

Most patients can return to work, drive, and resume daily activities. If polyps were removed, avoid heavy lifting over 25 pounds and strenuous exercise for 48 to 72 hours to reduce the risk of delayed bleeding.

Days 2 – 5

Back to normal.

You should feel completely recovered. If polyps were removed, continue avoiding intense physical activity until the timeframe Dr. Maher specified at discharge. Resume all regular medications unless instructed otherwise.

Eating and Drinking After Your Procedure

You may eat and drink after your procedure unless Dr. Maher gives you different instructions. Your digestive system has been empty, so ease back in gently.

Start With

  • Water, broth, or electrolyte drinks
  • Toast, crackers, or plain rice
  • Yogurt, applesauce, or bananas
  • Scrambled eggs or soup
  • Smooth peanut butter on white bread

Avoid First 24 Hours

  • Heavy, greasy, or fried foods
  • Spicy foods
  • Raw vegetables with skin or seeds
  • Alcohol (wait at least 24 hours)
  • Carbonated drinks if already bloated
Hydrate generously. The bowel prep for colonoscopy depletes fluids significantly. Drink more water, broth, and electrolyte beverages than you think you need for the first 24 to 48 hours. Dehydration is the most common reason patients feel unwell after their procedure.

Recovery Tips

Walking helps bloating

Light walking around your home helps move gas through your system faster than lying still.

Throat soreness after EGD

Warm tea, broth, or ice chips can soothe a mild sore throat. Avoid anything too hot until numbness fully wears off.

Sedation and appetite

Reduced appetite for the first few hours is normal. Do not force large meals. Your hunger will return naturally.

Avoid alcohol for 24 hours

Alcohol combined with residual sedation can cause dizziness, nausea, and impaired judgment even the day after your procedure.

Resuming Your Medications

Follow the specific instructions on your written discharge paperwork. These are general guidelines only.

Dr. Maher or a member of his team will review your medication plan before you leave our office. Always defer to the specific instructions you receive at discharge over these general guidelines.

Resume Right Away

  • Blood pressure medications
  • Thyroid medications
  • Most daily prescriptions (unless told otherwise)

May Need to Wait — Follow Discharge Instructions

  • Blood thinners and antiplatelets If polyps were removed, Dr. Maher may ask you to wait. Follow written instructions exactly.
    Warfarin Eliquis Xarelto Plavix Aspirin
  • NSAIDs — avoid 3 to 5 days after polyp removal Use acetaminophen (Tylenol) for mild discomfort instead.
    Ibuprofen Advil Motrin Aleve Naproxen
  • GLP-1 medications — do not resume until cleared by Dr. Maher
    Ozempic Wegovy Mounjaro Zepbound
  • Diabetes medications and insulin Resume once you are eating regularly. Contact us or your prescribing physician if unsure.
Not sure when to restart a medication? Call our office at (346) 637-4874 before taking anything you are uncertain about. It is always better to ask first.

Warning Signs That Require Immediate Attention

Complications after GI procedures are rare, but they can occur. Go to the nearest emergency room or call our office immediately if you experience any of the following:

Heavy or continuous rectal bleeding More than a tablespoon at a time, or bleeding that does not stop
Severe abdominal pain Pain that is getting worse, not better, over time
Fever above 101°F Within the first 48 hours after your procedure
Persistent nausea or vomiting Inability to keep fluids down after returning home
Black, tarry stools May indicate bleeding higher in the digestive tract
Difficulty breathing or chest pain Seek emergency care immediately — do not wait
Dizziness, fainting, or dehydration No urination, extreme thirst, or rapid heartbeat
Increasing abdominal swelling Visible distension or swelling that worsens over time
Important about delayed bleeding: Heavy bleeding from polyp removal can sometimes occur several days after the procedure, not just immediately afterward. If you notice significant bleeding at any point within the first two weeks, call our office right away.

Your Results and Next Steps

Same-Day Results

Dr. Maher discusses his initial findings with you before you leave the office. If your procedure was normal, he will tell you when to schedule your next one — typically 10 years for a routine screening colonoscopy with no findings, or 3 to 5 years if polyps were found.

Biopsy and Pathology Results

If tissue samples or polyps were sent to the lab, results typically take 3 to 7 business days. Our office will contact you directly with the results. You do not need to call us unless you have not heard from us within 10 business days.

Follow-Up Appointments

Depending on your findings, Dr. Maher may recommend a follow-up visit to discuss your results in detail, adjust medications, or plan ongoing care. Our team will let you know at discharge if a follow-up is needed.

Your Procedure Report

You will receive a copy of your procedure report at discharge. Keep it for your records. If you need an additional copy, contact our office or access it through our patient portal.

Common Post-Procedure Questions

Answers about memory loss from sedation, bloating, returning to work, diet, blood thinners, and post-procedure bleeding.

Call Our Office

I do not remember Dr. Maher talking to me after my procedure. Is that normal?
Yes. Sedation commonly affects short-term memory. Many patients do not remember the conversation they had in the recovery room. That is why we provide written discharge instructions and encourage your driver to be present when Dr. Maher reviews your findings.

How long will I feel bloated after my colonoscopy?
Bloating from the air used during the procedure usually resolves within a few hours. Walking helps move the gas through your system. If bloating persists beyond 24 hours or is accompanied by severe pain or swelling, contact our office.

When can I go back to work?
Most patients return to work the day after their procedure. If your job requires heavy lifting or strenuous physical activity, you may need an extra day or two, especially if polyps were removed.

Can I eat normally right away?
Yes, in most cases. Start with light, easy-to-digest foods and work your way back to your regular diet. Avoid heavy, greasy, or spicy foods for the first meal. If you had an upper endoscopy and your throat was numbed, wait until the numbness wears off before eating to avoid choking.

When should I restart my blood thinner?
This depends on which medication you take and what was done during your procedure. Follow the specific instructions on your written discharge paperwork. If you are unsure, call our office before taking it.

I see a small amount of blood in my stool. Should I worry?
A small amount of blood, especially with the first bowel movement after polyp removal, is common and usually not concerning. If the bleeding increases, becomes continuous, or you are passing large amounts of blood, call our office immediately or go to the emergency room.
