Recovering after gastroscopy

Overview

A gastroscopy is a procedure where a thin, flexible tube with a camera on the end is passed through your mouth and into your stomach to look at the lining of your upper digestive system. After the procedure, most people recover quickly and can go home the same day.

Gastroscopy is a very common procedure used to investigate symptoms like indigestion, heartburn, or stomach pain. Thousands are performed every day across the world.

Anyone of any age may have a gastroscopy if their doctor recommends it. Recovery is generally straightforward for most people, but very young children and older adults may need extra care and monitoring after the sedative.

Symptoms

Common symptoms

• Sore or scratchy throat
• Feeling bloated or gassy
• Mild nausea
• Drowsiness if you had sedation
• Slight discomfort in the throat or stomach

Symptoms in children

• Children may be more sleepy or irritable after sedation
• They might complain of a sore throat or tummy ache
• Crying or fussiness can be normal for a few hours

Symptoms in older adults

• Older adults may feel more drowsy or confused after sedation for a bit longer
• They may have a higher risk of falls, so careful supervision is needed
• Some may have a drier mouth or mild swallowing difficulty for a short time

Causes

Main causes

• Gastroscopy itself does not cause a disease — it is a diagnostic tool. Recovery symptoms are usually from the procedure: throat irritation from the tube, gas from air used to inflate the stomach, and lingering effects of sedation.

Risk factors

• Having a history of bleeding disorders
• Taking blood-thinning medications (talk to your doctor about this before the procedure)
• Older age or having other medical conditions may increase the chance of minor discomfort

When to see a doctor

See a doctor urgently if:

• If you have severe pain, vomiting blood, black stools, or trouble breathing – call emergency services immediately
• If you have a fever that does not go away, or any signs of infection

Book a routine appointment if:

• See your doctor for your scheduled follow-up appointment to discuss the results of the gastroscopy
• If you have ongoing mild symptoms like sore throat or swallowing difficulty that last more than a couple of days

Diagnosis

Recovery after gastroscopy is monitored by the medical team immediately after the procedure. They check your vital signs, make sure you can swallow safely, and watch for any complications before you go home.

Tests that may be done

• None after a routine gastroscopy, unless a biopsy (a small tissue sample) was taken – then your doctor will discuss the results later

What to expect at your appointment

You will rest in a recovery area until the sedative wears off. The staff will offer you a drink and light snack. You may be advised to have someone stay with you for 24 hours and not to drive, operate machinery, or make important decisions.

Treatment

Recovery from a gastroscopy is usually straightforward and does not require medical treatment. The focus is on rest, letting the sedation wear off, and managing minor discomfort at home.

Self-care at home

• Rest for the rest of the day – avoid driving, alcohol, and heavy lifting
• Start with sips of water, then light foods like toast or soup when your throat feels ready
• Suck on ice cubes or throat lozenges to soothe a sore throat
• Avoid hot or spicy foods for 24 hours
• If you had sedation, do not go back to work until the next day

Medical treatments

Medical treatment is rarely needed. If a complication like bleeding occurs, doctors may use medication to stop the bleeding or, in rare cases, perform another procedure to repair a tear. Always report any unusual symptoms to your healthcare provider who can advise on the right next steps.

Living with this condition

Most people return to normal activities the day after a gastroscopy. Your doctor will tell you if any follow-up is needed, such as reviewing biopsy results or arranging further tests.

Lifestyle tips

• Avoid strenuous exercise or heavy lifting for 24 to 48 hours after sedation
• Do not drive, bike, or use dangerous machinery for at least 24 hours if you had sedation
• Have a responsible adult stay with you overnight

Diet and exercise

You can eat normally once your throat feels comfortable. Start with soft, cool foods and gradually return to your usual diet. Gentle walking is fine after the sedation wears off, but avoid intense workouts for a day or two.

Mental health and emotional wellbeing

Some people may feel anxious about the procedure results or about having another one. It is normal to have questions. Talking to your doctor or a trusted friend can help. If you feel very worried, let your healthcare team know.

Prevention

Recovery problems after gastroscopy are rare and usually not preventable. Following pre-procedure instructions (like fasting) helps reduce risks. Good communication with your medical team about any medications you take is important.

Complications

If left untreated

• Complications are very rare but can include: infection from a biopsy site, a small tear in the lining of the oesophagus or stomach (perforation), or bleeding that may need treatment

Long-term outlook

The outlook after a gastroscopy is excellent. Almost everyone recovers fully within a day. Serious complications are extremely uncommon, and the procedure helps doctors find problems early, which is good for your health.
