Same-day doctor assessment, on-site tests, and rehydration — oral or IV — started before you leave. At our private medical centre near King's Cross.
“You can ride out a stomach bug. But every hour of fluid loss drains your strength, your salts and your recovery. Why suffer for days — when the right fluids and the right medication can put you back on your feet?”
Individual recovery varies.).
Some tummies are emergencies.
Severe, constant abdominal pain · a rigid, board-like tummy · black or bloody stools · vomiting blood · too weak to walk or speak · signs of severe dehydration (no urine, confusion, sunken eyes) — call 999 or go to your nearest A&E now. The clinic is for everything below that line.
On-site diagnosis
Doctor, tests and treatment under one roof.
Dehydration checked, not guessed
Bloods show exactly what you've lost.
Rehydration starts same visit
Oral plan or IV drip, on the spot.
Small illness, kept small
Early signs of bigger problems caught in time.
A doctor takes the story properly: what you ate, where you've travelled, who else is ill — then examines your abdomen and checks your vital signs.
Bloods for infection markers, kidney function, salts and glucose — the exact picture of what the fluid loss has done. Stool tests when symptoms persist or there's blood.
Abdominal ultrasound on-site when the story doesn't add up — gallbladder, appendix area, kidneys — so a “stomach bug” that's really something else gets caught now, not next week. Anything surgical → straight to A&E, with our findings in hand.
IV fluids with anti-sickness and the right medication where clinically appropriate, supervised by experienced doctors — or a precise home rehydration plan, diet guidance and a “when to come back” line. Sick notes and travel letters when you need them.
You leave with fluids on board, a plan in hand — and we check how you're doing.
Vomiting and diarrhoea drain more than water — they strip the salts your heart, kidneys and muscles run on. That's why a “two-day bug” can leave you weak for two weeks, and why dehydration sends thousands to A&E who never needed to get that far. Caught early, it's simple to fix. Left to run, a small illness becomes a big one. (小病拖成大病 — 我们的工作就是不让它发生。)
Kidney function, electrolytes and glucose tell us exactly how dehydrated you are — no guesswork, no “drink some water and see”.
IV fluids restore in an hour what sipping water takes days to do — with anti-sickness medication so it stays down.)
Children, older family members, pregnant women and anyone with diabetes or kidney conditions dehydrate faster — and need watching sooner, not later.
Stop the fluid loss early — and get back to your life, not your bed.
Most stomach bugs settle on their own — and we'll tell you when yours will. Stepping in is right when:
Tests show dehydration or salt imbalance that fluids alone at home won't fix fast enough.
Symptoms persisting, worsening, or you can't keep even water down.
A calculated, doctor-supervised intervention to cut the misery short: travel tomorrow, children at home, a week you can't lose.
Every IV is prescribed and supervised by experienced doctors. Antibiotics only when a tested cause calls for them — most stomach bugs don't.
Most cases are viral bugs or food poisoning. The skill is spotting the ones that aren't:
Symptoms lasting over two weeks, blood in your stool, or losing weight? That's a Gastroenterology work-up — we'll route you straight there.

Food poisoning two days before a long-haul flight; couldn't keep water down. Bloods showed early dehydration. IV fluids + anti-sickness that afternoon, home rehydration plan, fit-to-fly letter. On the plane, on schedule.

“Gastro” with pain that wouldn't settle. The ultrasound told a different story — gallstones. Treated for the symptoms, fast-tracked to the right surgeon with images in hand. A week of guessing, skipped.
Toddler, 24 hours of vomiting, worried parents, NHS line saying “wait and see”. Paediatric assessment, gentle rehydration, a clear red-flag plan for home. Back to nursery in two days — and the parents slept.

Thirst, dark or little urine, dizziness on standing, dry mouth, weakness. Our blood tests confirm it precisely — that's the point of testing before treating.
When tests show real fluid and salt loss, yes — it restores quickly what sipping water struggles to, with anti-sickness medication so it stays down. When you don't need one, we'll say so.
Yes — children have their own rapid pathway, and little ones dehydrate fastest, so sooner is better. Severe signs (no wet nappies, drowsy, sunken eyes) go to A&E first.
That's why we examine, test and scan. Gallstones, appendix warning signs, kidney stones — if the picture changes, you're fast-tracked the same day with our findings in hand.
Yes — issued on the spot when clinically appropriate.
Message your symptoms — we'll tell you when to come in. (中文也可以。)
