Overview
What you should know
Acute diarrhoea, often with vomiting: fluids first, then the warning signs.
Most acute gut infections are viral and pass within a few days. Fluids and rest come first. What matters is recognising when the fluid loss or the course calls for an assessment.
One address for your concern
Book an appointment or come by during opening hours. And if you are unsure whether we are the right address: come anyway; we will work it out with you.

What happens
What happens at aprioris
Our aim: to resolve your concern directly on site. Assessment, treatment and, where needed, a prescription or certificate. If specialist care is needed, we refer you on.
We listen to your concern, examine you carefully and put the findings in context. Then we discuss what happens next with you.
Every case is reviewed and signed off by a physician, either during your visit or shortly after. Anything that needs specialist care, we refer on, prioritised by urgency and with a written report. aprioris does not dispense medication itself.
Treatment
Treatment overview
What you can do yourself
- drink in small sips, spread across the day
- light food once you can tolerate it again
- rest until the symptoms ease
- hand hygiene, because many of these pathogens pass on easily

FAQ
Frequently asked questions
Do I need an appointment for this?
Not necessarily. You are welcome without booking during opening hours. If you book an appointment, you are seen at the agreed time. You can book online or by calling the practice.
What does the assessment cost?
aprioris is a medical practice licensed by the canton. Services covered by mandatory health insurance are billed accordingly. Your deductible and co-payment apply, as in any medical practice. Preventive services are paid for privately; prices are shown with each service.
What should I bring?
Your health insurance card. If you take medication, a current medication list or the packaging helps. For anything to do with vaccination, please bring your vaccination record.
When should I go straight to emergency care?
Blood in the stool or in vomit, severe abdominal pain with a rigid abdomen, marked fluid loss or confusion: have that assessed immediately, if in doubt through 144.
