If you’ve been dealing with bloating, gas, and a digestive system that never quite settles, and someone has used the letters SIBO in your direction, your next question is probably a practical one. Who do you actually see? A gastroenterologist? Your primary care doctor? Someone in the functional health world you found through a late-night search? Every option sounds reasonable, and the internet is full of confident opinions pointing in different directions.
The short version is that several kinds of doctors can play a role in SIBO care, and the best starting point depends on your symptoms, your history, and what you’ve already tried. This blog walks through what each type of provider typically offers, where each one tends to be strongest, and how to decide where to begin without wasting months going in circles.
SIBO stands for small intestinal bacterial overgrowth. According to the American College of Gastroenterology, it describes a condition in which an excess of bacteria builds up in the small intestine, where relatively few bacteria normally live. The symptoms it is associated with include bloating, gas, abdominal discomfort, and changes in bowel habits.
Here’s the catch, and it’s the reason the question of who to see is harder than it looks. Those symptoms overlap with a long list of other digestive conditions. Bloating and irregular digestion can come from food reactions, motility problems, stress, hormonal shifts, medication effects, and a range of other causes. That overlap is why SIBO is discussed so often, and also why it’s so frequently a topic of debate between doctors.
A symptom list can point toward SIBO, but it can’t confirm it, and it can’t tell you why it happened.
Several kinds of licensed providers work with people who have SIBO or suspected SIBO. None of them is the single right answer for everyone.
Most people who get lasting results end up working with more than one of these, and the order in which they see them matters less than finding someone who takes the whole picture seriously.
Gastroenterologists are well positioned to evaluate symptoms that could signal a structural or inflammatory condition, to perform procedures that look directly inside the digestive tract, and to prescribe medication when it’s appropriate. If your symptoms are severe, getting worse, or accompanied by warning signs, this is often the right first stop.
Where patients sometimes feel a gap is in time and scope. Specialist appointments are frequently short, and the focus naturally stays on the digestive tract itself. If the question you’re asking is “why does this keep coming back?” and the answer involves stress, hormones, sleep, or other body systems, a specialist visit may not have room for that conversation. That isn’t a criticism of gastroenterologists. It’s a reflection of how their role and their schedules are built.
Your primary care doctor knows your overall history, your medications, and your other conditions, which makes them a sensible place to start for many people. They can review your symptoms, order an initial workup, rule out common causes, and refer you to a specialist when needed.
Primary care also plays a role that’s easy to overlook: coordination. If you’re seeing a specialist, a dietitian, and a functional health doctor, someone should be keeping track of the whole picture so the pieces don’t pull in opposite directions.
The limitation is time. According to a time-and-motion study published in the Annals of Internal Medicine, physicians spent nearly twice as much time on electronic health records and desk work as on direct face time with patients during the clinic day. A complicated digestive history rarely fits comfortably into a short visit, so you may need to bring a clear written summary and expect a follow-up or two.
Functional health care is built around a different set of strengths. Appointments tend to be longer, and the evaluation is broader. Instead of asking only “which digestive condition is this?” a functional health doctor asks what else is going on in the body that might be contributing, and what has changed over the years that led up to the symptoms.
For someone with long-running digestive trouble, that wider lens can be the missing piece. Gut symptoms rarely exist in isolation. Stress, sleep, hormone changes, nutrition, past illnesses, and medication history can all play a part, and a provider who has the time to connect them can often see patterns a shorter visit would miss.
It’s worth being honest about the limits here too. Functional health doesn’t replace a gastroenterologist when something needs a specialist’s procedures or prescriptions. A good functional health doctor knows that, says so, and refers you when it’s the right call. Dr. Skidmore works this way, with a license and scope of practice she’s open about, and with a clear understanding of when a patient needs someone else.
A few other professionals often join the picture.
A registered dietitian can help you understand how food patterns and digestive symptoms relate, which is especially useful if you’ve been cutting foods out on your own and feel uncertain about whether you’re eating enough variety.
A mental health provider can be a surprisingly important part of the team. The gut and the nervous system are in constant communication, and long-running digestive symptoms often come with real stress, anxiety, and worry about food. Addressing that isn’t a side issue. It’s part of caring for the person who has the symptoms.
Depending on the situation, a pharmacist can also be a quiet ally, particularly when you’re managing multiple medications and want to understand how they interact with digestion.
One of the most important things to understand about SIBO is that the overgrowth itself is often not the whole story. The American College of Gastroenterology guideline discusses a range of underlying conditions and factors that are associated with SIBO, which is a strong reason to ask what may be contributing instead of focusing only on the label.
This is why people sometimes describe a frustrating cycle: symptoms improve, then return. When the factors that allowed the problem to develop haven’t been identified, it’s common for it to come back. That cycle is often what sends people looking for a second or third opinion, and it’s a good reason to choose a provider who is curious about the why.
It’s also a reason to be cautious of anyone who offers a quick, universal fix. Digestive health is individual. The same symptoms can have very different causes in two different people, and a plan that works beautifully for one may do nothing for another.
Here’s a practical way to think about your first step.
| Your Situation | A Reasonable First Stop | Why |
| New, severe, or rapidly worsening symptoms | Primary care or gastroenterologist | Important conditions need to be ruled out first |
| Symptoms with warning signs such as blood in the stool or unexplained weight loss | Prompt medical care | These need prompt evaluation, not a wait-and-see approach |
| Long-running symptoms and a sense that no one has connected the dots | Functional health doctor, alongside your regular doctor | A broader evaluation can look at what else is contributing |
| Already seen a specialist, and symptoms keep returning | Functional health doctor or dietitian | Focus shifts to underlying contributors and long-term patterns |
| Unsure where you fit | Primary care | A good coordinator can point you in the right direction |
This table is a general orientation, not a recommendation for any individual. Your own history will shape what makes sense, which is exactly why a conversation with a qualified provider is worth more than any chart.
Most digestive symptoms are uncomfortable but not dangerous. A few are different. Blood in your stool, black or tarry stools, unexplained weight loss, persistent vomiting, difficulty swallowing, severe or worsening abdominal pain, and symptoms that wake you from sleep are all reasons to seek prompt medical care from a doctor who can evaluate them properly.
If any of those apply to you, please don’t read another article first. Call your doctor.
Whoever you see, a few questions help you understand whether you’re in good hands.
Listen for answers that are specific to you and honest about uncertainty. A provider who says “it depends, and here’s how we’ll figure it out” is usually more trustworthy than one who promises a guaranteed outcome.
You’ll get far more out of any visit if you arrive prepared. A little organization turns a rushed appointment into a productive one, and it’s something you can do this week regardless of who you decide to see.
Bringing this kind of summary also helps with the coordination problem mentioned earlier. When every provider on your team is working from the same information, the pieces fit together far more smoothly, and you spend less energy repeating your story.
When symptoms are frustrating, it’s tempting to piece together a plan from articles, forums, and social media. The trouble is that digestive symptoms have many possible causes, and guessing wrong can mean months of effort in the wrong direction, new symptoms, or something serious going undiscovered.
A qualified provider brings something a search result can’t: an evaluation of you, with your history, your medications, and your goals in mind. That’s the part worth paying for, and it’s usually the fastest route to feeling better.
At True Health Clinic in Hesston, serving patients from Wichita and across Kansas, Dr. Skidmore starts with a long, careful conversation. New patient appointments are built to take a thorough history, because the story of how your symptoms developed often holds the most useful clues. Evaluation is individualized, and any specialty lab work is chosen based on what your history suggests rather than applied to everyone.
Dr. Skidmore works alongside your other doctors, not in competition with them. If your symptoms need a gastroenterologist or any other specialist, she’ll tell you, and she’ll help you think through what to bring to that appointment. If your care has felt fragmented, or you keep hearing “everything looks normal” while your gut tells you otherwise, a longer conversation focused on the full picture may be a helpful next step.
The best way to find out whether this fits is to talk. The free 15-minute phone consultation is a chance to share what’s been going on, ask how Dr. Skidmore approaches digestive concerns, and decide whether it makes sense to go further. There’s no obligation and no pressure.
