Let us start with the good news
The vast majority of abdominal pains that send someone searching for information at night are benign and self-limiting. Gastroenteritis, indigestion, intestinal colic, constipation, period pain, wind. They resolve in hours or a couple of days, need no investigation and certainly no operating theatre.
The trouble is that a small percentage of those pains is the first hour of something serious, and in those cases time changes the outcome. Which is why the signs are worth knowing — not to self-diagnose, but to know when to stop waiting.
The first sign: pain that will not settle and keeps rising
Colicky pain comes and goes: it grips, eases, grips again. Pain that installs itself, stays, and worsens progressively over hours is something else. That pattern — continuous, rising, not relieved by anything — is one to have assessed the same day.
And here is a detail that confuses many: intensity does not always track severity. Biliary colic can be the worst pain of someone's life and not be an immediate surgical emergency; a perforation in an older adult can hurt less than expected. What matters is the pattern and what accompanies it.
The second: where the pain settles
Diffuse pain moving around the abdomen is usually less worrying than pain concentrating on one point. When pain starts around the navel and then settles in the lower right, that migration is practically the signature of appendicitis.
When it settles under the ribs on the right, after eating, with nausea, the gallbladder is the first suspicion. When it settles in the lower left, with fever and a change in bowel habit, diverticulitis comes to mind. Each location tells a different story, which is why the doctor asks in such detail where it started and where it moved.
The signs that mean going to an emergency department, now
There are no nuances here. Go immediately with any of these: SEVERE ABDOMINAL PAIN THAT DOES NOT SETTLE WITHIN A FEW HOURS OR THAT WORSENS. FEVER WITH LOCALISED ABDOMINAL PAIN. VOMITING THAT PREVENTS KEEPING FLUIDS DOWN, or vomiting of intestinal appearance.
Also: A DISTENDED ABDOMEN WITH NO GAS OR BOWEL MOVEMENTS. A HERNIA THAT HAS TURNED HARD AND PAINFUL AND CANNOT BE PUSHED BACK IN. VOMITING BLOOD OR BLACK STOOLS. YELLOWING OF SKIN OR EYES with pain. And a rigid, board-like abdomen that hurts on the slightest movement or on walking. Any of these justifies an emergency assessment within the hour.
The mistakes that cost most
The first: taking a strong painkiller and waiting to see. The analgesic does not cure the cause and can mask the evolution, which is precisely the information the doctor needs to decide. Paracetamol on the way to hospital is reasonable; self-medicating for two days with something stronger is not.
The second: the antibiotics left over from last time. Taking antibiotics without a diagnosis can blunt an infective picture just enough to delay the consultation, without resolving it. The third, and commonest: waiting for Monday. Many abdominal emergencies worsen precisely over the weekend, and waiting two days turns a simple operation into a complicated one.
What to expect on arrival
Assessment begins with history and examination — where it hurts, since when, what makes it worse, how the abdomen feels on palpation — and continues with labs and, as the case requires, abdominal ultrasound or CT. From that it is decided whether there is an immediate surgical indication, a deferred one, or whether management is medical.
And it is worth saying: not every abdominal emergency ends in theatre. Many cases of diverticulitis, some adhesive obstructions and certain cases of cholecystitis are managed with antibiotics, fasting and observation, with planned surgery later if needed. Going to the emergency department does not mean you will be operated on; it means someone will look at the abdomen in time.
Bring your studies and settle the question
One consultation with your ultrasound or CT in hand is worth more than ten internet searches. Book by phone or through the form and you will be told what is there, what it means and what your options are.
