Gastroenterology Treatment in NYC
QUICK ANSWER

What is functional gastroenterology treatment?

Functional gastroenterology, also called integrative gastroenterology, looks for why digestion has gone wrong, then treats those causes rather than just the symptoms. At Patients Medical that means a long first visit, targeted tests such as breath tests for SIBO and stool or blood tests, and a plan that may combine diet changes, treatment of bacterial overgrowth, reflux care, gut-brain therapies and nutrient repletion. A gastroenterologist performs procedures like colonoscopy and endoscopy; we arrange those when your symptoms call for one.

AT A GLANCE

Treatments

Guided diets, SIBO and reflux care, gut-brain therapies, nutrient repletion

How it works

Consultation and targeted testing first, then a plan that treats causes in order

Who it's for

Adults with ongoing gut symptoms, or told “your scope is normal” but still unwell

Timeline

Many notice changes within weeks; long-standing problems usually take months

Is this care right for you?

Bloating, IBS, Constipation or Diarrhea? Symptoms We Treat

Our care is for adults whose digestive symptoms keep coming back, haven’t settled with over-the-counter remedies, or remain after tests came back normal. IBS alone affects about 12% of people in the US, and women up to twice as often as men.

Conditions we treat

Your plan addresses whichever of these your history and testing point to. Inflammatory bowel disease and ulcers are managed alongside your gastroenterologist.

How treatment works

How We Treat IBS, SIBO, Reflux and Constipation

Each common cause of ongoing gut symptoms has a matching treatment, based on current gastroenterology guidelines. Every step is supervised by a physician.

IBS treatment

Diagnosed from your symptoms and a few targeted tests, not by ruling out everything. Treated with diet, gut-brain therapy and medicine when needed.

What causes IBS

AlcoholSIBO testing & treatment

Confirmed with a breath test, then treated with a targeted antibiotic. Methane overgrowth is linked to constipation and treated differently.

Gut testing explained

Reflux, gastritis & heartburn

An 8-week acid-reducer trial for classic symptoms, meal timing and sleep position changes, then a plan to step down medicine when you can.

Acid reflux & GERD

Food intolerances & triggers

A guided, time-limited elimination and reintroduction diet such as low-FODMAP, plus testing for celiac disease before anyone cuts out gluten.

Food sensitivities vs. allergies

Gut-brain axis therapy

Gut-directed therapies and stress care, which gastroenterology guidelines now recommend as part of standard IBS treatment, not a last resort.

The gut-brain axis

 

Chronic constipation

Fiber, fluid and movement plans, a check for methane overgrowth, thyroid and medication causes, and pelvic-floor referral when needed.

Constipation & slow digestion

Gut inflammation & nutrient absorption

Blood and stool markers to separate inflammation from functional symptoms, and repletion of iron, B12 or vitamin D found low.

Inflammation treatment

Endoscopy & colonoscopy referral

Warning signs or age-based screening are referred to a board-certified gastroenterologist for endoscopy or colonoscopy.

Gastrointestinal testing

How treatment works

How Our Gastroenterology Treatment Works, in 4 Steps

Four clear steps, so you always know what is being tested, what is being treated and what comes next.

01

In-depth consultation

A 60–90 minute first visit covering your symptoms, diet, medications, stress, sleep and past tests, plus a screen for warning signs.

Your first visit

02

Testing to guide treatment

As appropriate: breath testing for SIBO, stool tests, celiac and inflammation blood tests, and nutrient levels. Breath tests need a short prep, which we explain in advance.

Stool testing, Blood testing

03

Your treatment plan

Your physician treats the most important findings first, in order, so you aren’t trying ten fixes at once.

Why digestive treatments fail

 

04

Follow-up & reintroduction

Regular check-ins adjust treatment, bring foods back in, and taper medicines you no longer need.

Nutritional guidance

How treatment works

Integrative Gastroenterology Treatments We Offer in NYC

Most plans combine two or more of these. Your physician recommends only what your results and symptoms support.

Low-FODMAP & Elimination Diets

A structured low-FODMAP or elimination phase, followed by planned reintroduction so your diet doesn’t stay restricted for good.

SIBO & IMO Treatment

Breath-test-confirmed overgrowth treated with a gut-targeted antibiotic, then steps to address what allowed it, such as slow motility or medications.

Reflux, Gastritis & H. pylori Care

Acid control where needed, H. pylori testing and treatment, and meal-timing and sleep changes, with a planned attempt to step medicine down once symptoms settle.

Gut-Brain Therapies

Stress reduction, breathing techniques and referral for gut-directed psychotherapy, which IBS guidelines recommend alongside diet and medicine.

Leaky Gut & Barrier Support

An anti-inflammatory diet, treatment of underlying triggers and careful use of supplements, reviewed against your other medicines.

Constipation & Motility Plans

Fiber, fluid and activity targets, a review of constipating medicines, and treatment for methane overgrowth when breath testing finds it.

Targeted Supplements

Used selectively: soluble fiber and peppermint oil for some IBS symptoms. Probiotics are matched to a clear reason, since the AGA doesn’t recommend them for bloating.

Nutrient Repletion

Iron, B12, vitamin D and others found low on testing, restored by mouth or IV when absorption is poor, then rechecked.

Specialist Coordination

Referral to board-certified gastroenterologists for endoscopy, colonoscopy or IBD care, with results folded back into your plan.

Functional vs. conventional gastroenterology

Functional Gastroenterology vs. a Conventional GI Visit

These roles work best together. A gastroenterologist rules out and treats structural disease; functional gastroenterology care spends the time on the problems that remain.

Often seen together

Tired, foggy or anxious too? We treat it in the same plan

Gut symptoms rarely travel alone. Poor absorption can leave you low in iron or B12, broken sleep from reflux drains energy, and the gut-brain connection links digestion with mood. When these show up together, your plan covers both.

What to expect

What Results Can You Expect From Gut Treatment?

Individual results vary. Your physician will set realistic goals with you at your first visit.

How Long Does Gastroenterology Treatment Take?

1–2 Weeks Consultation, testing and your personalized plan
2–8 weeksElimination phase, SIBO treatment or an acid-reducer trial; many notice changes here
2–3 monthsFoods reintroduced, medicines reviewed and stepped down where possible
OngoingOccasional check-ins to keep progress and handle flare-ups

Timelines depend on the cause, how long symptoms have lasted, other health conditions and the treatment approach.

FAQS

Gastroenterology Treatment in NYC

Still unsure? Call us at (212) 794-8800.

An approach to digestive care that focuses on how the gut is working: diet, the gut microbiome, motility and the gut-brain connection. Our physicians test for causes like SIBO, food triggers and nutrient gaps, and build a step-by-step plan around them.

No. A board-certified gastroenterologist is a specialist trained to perform scopes and treat structural and inflammatory disease. Functional gastroenterology care spends more time on diet, microbiome and lifestyle causes. Many patients do best with both, and we coordinate with gastroenterologists when needed.

We don’t perform procedures in our office. When your symptoms or age call for one, we refer you to a board-certified gastroenterologist and use the results in your plan. Colon cancer screening is recommended from age 45 for people at average risk.

Look for a physician who tests for causes such as SIBO, food intolerances and celiac disease, rather than only suggesting probiotics. Gastroenterology guidance notes there’s little evidence probiotics help bloating, while diet and gut-brain therapies can. Chronic bloating and gas

A gut health specialist finds out why digestive symptoms keep coming back, using targeted breath, stool and blood tests, then treats those causes with diet, gut-brain care, SIBO treatment, nutrient repletion and medicine when needed. At Patients Medical this care is physician-led and coordinated with gastroenterologists for any scope you need.

Yes. The most common causes of gastritis are H. pylori infection and regular use of NSAID pain relievers such as ibuprofen, with alcohol another trigger. We test for H. pylori, review your medicines, and plan acid control and diet changes, referring for an endoscopy if you have warning signs.

Yes. We diagnose IBS from your symptoms with a few targeted tests, then combine diet, gut-directed stress care and medicines when needed. Routine colonoscopy isn’t recommended for IBS under 45 without warning signs. Functional medicine for IBS

With a breath test after a short prep that includes fasting and avoiding certain medicines. If it’s positive, treatment is usually a gut-targeted antibiotic, plus steps to address why it developed. Guidelines advise against treating SIBO without testing.

Yes. We look for diet, medication, thyroid and microbiome causes, including methane overgrowth for constipation and celiac or inflammation for diarrhea, and refer for a scope if warning signs appear. Chronic diarrhea and gut inflammation

Only the ones your symptoms point to. That may include a breath test, stool tests, celiac and inflammation blood tests, and iron, B12 or vitamin D levels. Gut health testing explained

Right away for blood in your stool, black stools, vomiting blood, trouble swallowing, unintended weight loss or new bowel changes after 45. These need a scope first. We help arrange that and continue your care afterward.

Many people notice changes within a few weeks of starting a plan. Long-standing problems usually take two to three months, including time to reintroduce foods and review medicines.
