What is the best WhatsApp chatbot for gastroenterologists in Brazil?
The best WhatsApp chatbot for gastroenterologists in Brazil is the one that answers on the number the clinic already uses, with business rules written by you. An AI agent on WhatsApp for a gastroenterologist is CertuAI's automatic assistant. It sends the colonoscopy and endoscopy prep exactly as the clinic wrote it, flags that a test with sedation requires a companion, gives fasting instructions, prices and accepted health insurance, books the appointment and never makes decisions about medication.

Does the AI send the right colonoscopy prep?
It sends what you wrote, without rewriting it. The prep goes into the Brain as a text of yours, with the laxative brand, the times, what can be eaten in the days before and what to do if it doesn't work. The AI repeats that text and it stays in the conversation, so the patient rereads it at midnight without needing anyone.
The thing to watch is having a single text. If the front desk hands out a paper and the Brain has another version, the patient will follow whichever arrived last. Copy the paper the clinic already uses, without summarizing, and update both on the same day when it changes.
Medication on the day of the test: how far does the AI go?
It repeats the rule and never decides. On a health account, the AI doesn't recommend medication, doesn't calculate doses and doesn't say to stop anything, and this limit holds above whatever is written in the practice's instructions. Anticoagulants, insulin and blood pressure medication are exactly the kind of question that needs to reach a person.
In practice, write two things: the general rule the clinic already gives everyone, and the sentence that sends the rest to the team. That way the patient gets the standard answer right away and the unusual case reaches whoever decides, instead of dying in a generic reply.
What does the AI do with each gastroenterology message?
| Patient message | What the AI does |
|---|---|
| "Send the colonoscopy prep again" | Resends your text, in full |
| "Can I take my blood thinner?" | Repeats your rule; anything outside it goes to the team |
| "Can I go alone and drive afterward?" | Answers with the companion and transportation rule |
| "I have bleeding that won't stop" | Tells them to call 192 (Brazil's emergency medical line) or go to the emergency room |
| "How much is a private endoscopy?" | Answers with the price you registered |
| "The laxative didn't work" | Follows your written instruction and alerts the team if it doesn't cover the case |

What changes in the clinic with an AI agent?
What changes is who answers first: the message no longer waits for you and is answered right away. Here are four everyday situations at the clinic before and after the CertuAI agent.
TodayTest canceled on the day because the prep was misunderstood
With CertuAIThe prep arrives in writing and stays in the conversation for the patient to reread
TodaySedated patient with no companion and the slot is lost
With CertuAIThe companion rule is stated when booking and in the reminder
TodayFront desk repeating the same fasting instructions thirty times a day
With CertuAIThe AI answers the fasting question and the front desk takes care of whoever is in the clinic
TodayA prep question at eleven at night goes unanswered
With CertuAIAnswered right away, with your text
What does a conversation handled by the AI look like?
Example conversation
Clinic AI agent
Customer: Can you send the colonoscopy prep again, please?
AI agent: Of course. The colonoscopy prep, in the clinic's words: what you registered.
Customer: Do I need to come with someone? Can I drive afterward?
AI agent: With sedation you can't drive and need to leave with someone. The reminder the day before repeats this.
Is an AI agent or manual customer service better for gastroenterologists?
The agent wins at repetitive tasks, and the person keeps winning at what takes judgment. Done manually, someone at the clinic has to stop what they are doing; with the CertuAI agent the reply goes out on its own and you join the conversation whenever you want.
| Aspect | The manual way | With the CertuAI agent |
|---|---|---|
| Colonoscopy prep | Explained over the phone, written down wrong, and the test is canceled on the day | Sent in writing, word for word as you wrote it |
| Companion for the sedation | The patient finds out at the front desk and goes back home | Told when booking and repeated in the reminder |
| "Do I take my blood pressure medication that day?" | A different answer depending on who picks up | Doesn't decide: repeats your rule and passes along anything outside it |
| After-hours message with a fasting question | Only seen in the morning, when the fast has already been broken | Answered right away, at any hour |
| Bleeding that won't stop | Sits in the message queue | Gets the instruction to call 192 (Brazil's emergency number) right away |
What does the WhatsApp agent do for gastroenterologists?
It handles the customer service that is yours today. You teach the business once in the Brain, CertuAI's knowledge base, and the agent answers patients your way, with your rules.
Test prep in your own words
Colonoscopy, endoscopy, abdominal ultrasound and blood work, each with the prep your clinic uses. The agent doesn't summarize or adapt: it repeats.
Companion and transportation after sedation
Anyone having a test with sedation can't drive and needs to leave with someone. The agent says so when booking and the reminder the day before repeats it.
Ongoing medication on the day of the test
The clinic writes the rule, and anything outside it goes to the team. The agent never decides on its own to stop or keep a medication.
Price, health insurance and authorization
Answers the private price, the list of accepted health insurance plans and what needs authorization beforehand, the way you wrote it.
Emergency signs go straight to 192 (Brazil's emergency number)
Bleeding that won't stop, chest pain, shortness of breath and fainting immediately get the instruction to seek emergency help, before any question.
What questions do patients send on WhatsApp?
They are always the same, and the agent answers each one on its own. These everyday messages at the clinic no longer depend on you having your phone in hand.
How does the agent start answering at the clinic?
In three steps, on the same day. No installation, no code and no changing the number patients already know.
Teach your business
In one conversation, you explain services, prices, hours and rules, as you would to a new employee.
How much does an AI agent on WhatsApp cost for gastroenterologists?
The Start plan costs US$ 75 per month and already includes the WhatsApp agent, your business's Brain, the CRM, automatic follow-up and the AI assistants, which come with every paid plan. Pro costs US$ 120 per month and adds the landing page, the wallet and 10 people on the team instead of 5. No lock-in contract and no setup fee.
Get started now
Create my agentWhat needs to be ready before turning the agent on at the clinic?
The agent answers what is written, and nothing beyond that. Have these points defined before you connect WhatsApp.
- The complete prep for each test, written the way you hand it out today on paper
- The companion and transportation rule after sedation
- What to do with ongoing medication, blood thinners and diabetes on the day of the test, or the sentence that sends that question to the team
- Fasting for each test, in hours, and what can be drunk
- Private prices, accepted health insurance plans and what requires prior authorization
- The phone number and hours of whoever answers prep questions outside business hours
Whether the agent can book the test directly or whether every test goes through the front desk after the appointment.
The most common mistake: Giving the agent a shortened prep that differs from the paper the clinic hands out at the front desk. Two different texts about the same test is the shortest path to the test being canceled on the day. Read how to fix this.
Gastroenterologist FAQ
Does the agent send the test prep on its own?
Yes, with the text you registered, and it stays in the conversation for the patient to reread as many times as they want. It doesn't create prep instructions or mix in the ones for another test.
And when the patient asks whether they can take their medication?
If your rule covers the case, it repeats the rule. If not, it doesn't decide: it passes the question to the team with what the patient wrote.
Does it warn about the sedation companion?
Yes, when booking and again in the reminder, which goes out 24 hours and 1 hour before by default.
Can the AI book directly on the clinic's calendar?
With Feegow, yes: it sees the open slots for the procedure and only says booked after Feegow confirms. Without an integration, it takes down the request and the front desk books.
Other clinic questions CertuAI has answered

In short
