Waking with upper abdominal pain can be worrying, especially when it keeps happening after dinner or during the night. If you are experiencing gallbladder pain at night, it is natural to wonder whether it could be linked to gallstones or another gallbladder problem.
This pattern is more common than many people realise. Gallbladder pain often appears after eating, particularly after a rich or fatty meal, and it may build into a steady discomfort under the ribs on the right-hand side or in the upper middle part of the abdomen. For some people, it settles after a while. For others, it returns again and again, often at the most inconvenient time of day.
At Sonorad, we regularly see patients who want clear answers about recurring abdominal pain and whether a gallbladder ultrasound is the right next step. Understanding why symptoms often flare at night, and why fasting matters before the scan, can help you prepare properly and get the clearest assessment possible.
Why does gallbladder pain often happen at night?
In many cases, the timing comes down to digestion. The gallbladder stores bile and releases it when you eat, especially when a meal contains more fat. If gallstones are present or the gallbladder is irritated, that squeezing action can trigger pain.
Because dinner is often the heaviest meal of the day, symptoms may begin in the evening or wake you during the night. This is one reason patients often describe a repeating pattern of pain after eating, followed by discomfort that seems worse once they are trying to rest.
What gallbladder pain can feel like
Gallbladder pain is not always easy to identify at first. Some patients expect a sharp stabbing pain, while others notice a dull, gripping or tight sensation. Pain under the right ribs, pain in the upper middle abdomen, discomfort after a fatty or heavy meal, pain that builds and lasts for 30 minutes or more and nausea, bloating, or feeling generally unwell.
Some people also feel pain spreading towards the back or right shoulder blade area. If the same pattern keeps returning, it is worth getting it checked rather than assuming it is simple indigestion.
Can gallbladder pain come and go?
Yes. Gallbladder pain can be intermittent. Some patients have long gaps between episodes, while others notice attacks becoming more frequent over time. A symptom that settles on its own can still need investigation, particularly if it keeps returning after meals or overnight.
Common signs that gallbladder pain may need checking
Not every episode of upper abdominal pain is caused by the gallbladder, but certain features make it more likely that the gallbladder should be assessed.
You may want to consider a scan if you have any of the following symptoms: repeated pain after eating, pain that tends to happen in the evening or overnight, discomfort under the right ribcage, nausea with upper abdominal pain, bloating or fullness after fatty foods or symptoms that keep returning without a clear explanation
If this sounds familiar, an upper abdominal ultrasound scan may help assess the gallbladder and surrounding organs.
When a gallbladder ultrasound may be helpful
A gallbladder ultrasound is often one of the most useful first steps when gallstones or gallbladder-related symptoms are suspected. It is a non-invasive scan that uses sound waves to create real-time images of the upper abdominal organs.
At Sonorad, an upper abdominal ultrasound can help assess structures such as the gallbladder, liver, pancreas and nearby areas. The scan may help identify: gallstones within the gallbladder, signs of gallbladder irritation or inflammation, gallbladder wall thickening, bile duct changes and other upper abdominal causes of pain
Ultrasound does not involve radiation, and the examination is usually straightforward and well-tolerated.
What to expect during the scan
During the appointment, gel is applied to the skin, and a handheld probe is moved across the abdomen to capture images. You may be asked to change position or hold your breath briefly at certain moments so the organs can be seen more clearly.
Most patients find the scan comfortable, although the probe may feel a little tender if the area is already sore.
If you are ready to arrange an assessment, you can book a diagnostic ultrasound scan directly with Sonorad.
Why fasting matters before a gallbladder ultrasound
This is one of the most important parts of scan preparation.
The gallbladder needs to be seen as clearly as possible during the examination. When you fast, the gallbladder stays fuller, which usually makes it easier to assess. If you eat shortly before the appointment, the gallbladder contracts as part of digestion and may be less clearly seen on the scan.
That means fasting is not a minor detail. It can have a direct impact on how well the gallbladder can be assessed and how useful the scan is.
How long to fast before a gallbladder ultrasound
For Sonorad’s upper abdominal and gallbladder ultrasound preparation, patients are generally advised to fast for 6 hours before the scan. Water is usually allowed during this time. You can read Sonorad’s full ultrasound scan FAQs before your appointment.
Can I drink water before the scan?
In most cases, yes. Water is usually fine and can help you stay comfortable during the fasting period. It is best to avoid food, milky drinks and anything that may stimulate digestion unless you have been told otherwise for your specific appointment.
Do I need a full bladder, too?
Usually not for a gallbladder-focused upper abdominal scan. A full bladder is more commonly needed for certain lower abdominal or pelvic ultrasound appointments, not for routine gallbladder assessment.
What happens if the scan shows gallstones?
If gallstones are seen, the next step depends on your symptoms and the scan findings. Some people have gallstones without symptoms, while others have repeated pain, inflammation, or signs that the gallbladder is not functioning comfortably.
Your scan results may help guide whether you should: monitor symptoms, discuss treatment options with your GP or specialist, seek further medical review and consider referral if symptoms are recurring or more severe.
At Sonorad, the aim is to give you a clear, timely assessment so you are not left guessing what to do next.
When to seek urgent medical advice
Although many gallbladder problems are not emergencies, some symptoms should not be ignored.
Seek urgent medical advice if you have: severe or worsening abdominal pain, pain lasting several hours, fever or shivering, yellowing of the skin or eyes, repeated vomiting, pain with marked tenderness or feeling faint and pain spreading through to the back and not settling.
These features can suggest a more significant problem and should be assessed promptly.

A clear next step when symptoms keep returning
If you are noticing gallbladder pain at night, especially after meals or in a repeating pattern, it is worth taking seriously. Persistent or recurrent symptoms should not be dismissed as “just indigestion” without proper assessment.

Gallbladder Ultrasound Scan FAQs
Why does gallbladder pain often get worse at night?
Gallbladder pain often follows eating, and for many people, the evening meal is the richest or heaviest meal of the day. The gallbladder contracts to release bile to help with digestion. If gallstones are present or the gallbladder is irritated, this can trigger pain that appears later in the evening or during the night. That is why some patients notice a pattern of pain after dinner, discomfort when lying down to rest, or episodes that wake them from sleep.

What does gallbladder pain feel like?
Gallbladder pain is commonly felt in the upper right side of the abdomen, just under the ribs, although some people feel it more centrally in the upper tummy. It may feel steady, tight, gripping, or severe rather than cramp-like.
Some patients also report nausea, bloating, pain after fatty food, or discomfort that seems to travel into the back or right shoulder blade. The exact feeling varies from person to person, which is why a scan can be helpful when symptoms keep returning.
Can gallbladder pain be mistaken for indigestion or acid reflux?
Yes, very easily. Gallbladder pain can overlap with indigestion, bloating, reflux, or upper abdominal discomfort from other causes. The difference is often in the pattern. Pain that keeps happening after meals, particularly fatty meals, or that tends to occur at night or under the right ribs may point more strongly towards the gallbladder. If symptoms are repeating or becoming more intense, it is sensible not to rely on guesswork alone.
Do I need to fast before a gallbladder ultrasound?
Yes, in most cases, fasting is recommended before a gallbladder or upper abdominal ultrasound. Fasting helps the gallbladder remain fuller so it can be assessed more clearly. If you eat shortly before the scan, the gallbladder contracts as part of digestion, which can make imaging less helpful. Good preparation gives the best chance of a clear result and helps avoid unnecessary repeat imaging.
How long should I fast before a gallbladder ultrasound?
For Sonorad’s upper abdominal and gallbladder scan preparation, fasting is generally advised for 6 hours before the appointment. Water is usually allowed. If you have diabetes, take regular medication, or have any concerns about fasting, it is worth checking your appointment instructions in advance so you know exactly how to prepare safely.

Can I drink water before a gallbladder ultrasound?
Yes, water is usually allowed. In fact, staying hydrated can make the fasting period more manageable. The main point is to avoid food and anything likely to stimulate digestion before the scan unless you have been given different instructions. If in doubt, check Sonorad’s preparation guidance before attending.
Can a gallbladder ultrasound miss gallstones?
Ultrasound is very useful for assessing the gallbladder, but no test is perfect in every situation. Factors such as body habitus, bowel gas, scan preparation, or the position of the stones can affect what is seen. That is one reason preparation matters. If symptoms strongly suggest a gallbladder problem but the scan does not fully explain them, further clinical review may still be appropriate.
Is a gallbladder ultrasound painful?
The scan itself is usually painless. The probe is moved gently over the upper abdomen with gel on the skin. If the area is already tender, you may feel some temporary discomfort when pressure is applied, but most patients tolerate the scan very well. It is a straightforward and non-invasive test.
What happens after the scan if my results are normal but the pain continues?
A normal scan can be reassuring, but it does not always explain every symptom. If pain continues, the next step may be a review with your GP or specialist to look at other possible causes of upper abdominal pain. Sometimes symptoms that feel like gallbladder pain are linked to the stomach, liver, pancreas, bowel, or another abdominal issue. The scan is an important part of the picture, but it should always be considered alongside your symptoms.
Do I need a referral for a gallbladder ultrasound at Sonorad?
In many cases, no referral is needed to arrange a diagnostic ultrasound appointment at Sonorad. This can make it easier for patients who want prompt reassurance or assessment of ongoing symptoms. If you are unsure which scan is most appropriate, Sonorad’s team can help guide you before booking.
What should I wear or bring to my appointment?
It is sensible to wear comfortable clothing that allows easy access to the abdomen. You may also want to bring photo ID and any relevant medical information, such as previous scan results, clinic letters, or a short note of your symptoms and when they tend to happen. Small details like whether the pain comes after meals, overnight, or with nausea can be very helpful.
When should I seek urgent help rather than book a routine scan?
If your pain is severe, lasts for hours, or is associated with fever, jaundice, repeated vomiting, or feeling faint, urgent medical advice is more appropriate than waiting for a routine appointment. A private scan can be helpful for ongoing or recurring symptoms, but red-flag symptoms need prompt clinical assessment.
