When Should You See a Gastroenterologist?
Consider seeing a gastroenterologist when digestive symptoms are persistent, recurring, worsening, or interfering with daily life — or when a symptom like blood in the stool, difficulty swallowing, or unexplained weight loss appears. A gastroenterologist evaluates the digestive tract and liver to determine what is causing your symptoms and whether testing or treatment is appropriate.
- Persistent or severe abdominal pain
- Recurring heartburn or acid reflux
- Bloating and excessive gas that won’t resolve
- Constipation or chronic diarrhea
- Blood in the stool or rectal bleeding
- Difficulty or pain when swallowing
- Ongoing nausea or vomiting
- A noticeable change in bowel habits
- Unexplained weight loss
- Abnormal liver enzymes on a blood test
- Fatty liver noted on imaging
- Yellowing of the skin or eyes (jaundice)
- Persistent digestive problems without a clear cause
When symptoms deserve specialist evaluation. A single episode of indigestion is usually nothing to worry about. But symptoms that keep coming back, steadily worsen, wake you at night, or are paired with warning signs like bleeding, trouble swallowing, or weight loss are worth discussing with a gastroenterologist. These symptoms can have many possible causes, and only an individualized medical evaluation can determine what’s behind them.

Digestive Conditions Our Gastroenterologist Treats
United Gastroenterology Associates evaluates and manages the full range of digestive and liver conditions for Fulshear-area patients — from common complaints to inflammatory bowel disease and liver disorders. Each links to more detail if you’d like to read further.
GERD & Acid Reflux — Frequent heartburn, regurgitation, or a sour taste that keeps returning may be GERD.
Gastritis — Inflammation of the stomach lining can cause upper abdominal pain, nausea, and fullness.
Abdominal Pain — Recurring or severe abdominal pain warrants evaluation when it persists.
Bloating & Excess Gas — Ongoing bloating may point to constipation, IBS, or other conditions.
Irritable Bowel Syndrome — Cramping, bloating, and alternating diarrhea and constipation, manageable once diagnosed.
Crohn’s Disease — Inflammatory bowel disease causing pain, diarrhea, and weight loss.
Ulcerative Colitis — Affects the colon and rectum; ongoing GI care helps control flares.
Chronic Constipation — Constipation that persists despite diet and lifestyle changes.
Chronic Diarrhea — Diarrhea lasting more than a few weeks deserves evaluation.
Rectal Bleeding / Blood in Stool — Should never be assumed to be “just hemorrhoids”; it warrants evaluation.
Hemorrhoids — Common but often uncomfortable; usually treatable.
Difficulty Swallowing — Trouble swallowing or food sticking should be evaluated.
Celiac Disease — An immune reaction to gluten that can damage the small intestine.
Nausea & Vomiting — Persistent nausea or vomiting may warrant upper GI evaluation.
Gallbladder & Biliary Disorders — Pain after fatty meals can point to gallbladder or bile-duct problems.
Pancreatic Disorders — The pancreas plays a key role in digestion and requires specialist evaluation.
Acid Reflux & GERD Treatment Near Fulshear
If you have frequent heartburn, a gastroenterologist can determine whether it’s gastroesophageal reflux disease (GERD) and how to manage it. Reflux that occurs more than a couple of times a week, or that keeps returning despite over-the-counter remedies, is worth evaluating — both to relieve symptoms and to protect the esophagus over time. Fulshear-area patients often describe:
- Burning in the chest (heartburn), especially after meals or lying down
- Regurgitation of food or a sour, acidic taste
- A sensation of a lump in the throat
- Chronic cough or frequent throat clearing
- Hoarseness or a raspy voice
- Difficulty swallowing
Depending on your symptoms and history, your gastroenterologist may recommend lifestyle and dietary strategies, medication, or an upper endoscopy. Learn more about acid reflux and GERD care.
Bloating & Abdominal Pain Evaluation
Recurring bloating and abdominal pain shouldn’t automatically be dismissed as “just gas.” When these symptoms happen often, a gastroenterologist can help determine what’s actually driving them. Because they overlap with so many conditions, they benefit from a thoughtful evaluation rather than guesswork. Persistent bloating or abdominal pain can be related to:
- Diet-related sensitivities and eating patterns
- Constipation
- Irritable bowel syndrome (IBS)
- Gastritis or acid reflux
- Gallbladder problems
- Inflammatory conditions of the digestive tract
- Other gastrointestinal disorders
Recurrent or severe abdominal pain, pain with weight loss, or pain that wakes you at night should always be evaluated. Explore bloating & gas and abdominal pain care.
Screening & Evaluation
Colonoscopy Near Fulshear, TX
Fulshear-area patients seeking a colonoscopy can schedule with United Gastroenterology Associates through our nearby Katy office. A colonoscopy lets a gastroenterologist examine the lining of the colon and rectum using a thin, flexible camera — used both to screen for colorectal cancer and to evaluate specific digestive symptoms.
Screening. One of the most effective ways to detect colorectal cancer early — and uniquely, it can find and remove precancerous polyps during the same procedure, potentially preventing cancer before it starts.
Evaluation. Your physician may recommend it to investigate rectal bleeding, persistent changes in bowel habits, chronic diarrhea or abdominal symptoms, polyps, or a personal or family history that raises risk when clinically relevant.
Current guidelines generally recommend average-risk adults begin colorectal cancer screening at age 45, with earlier or more frequent screening for those at higher risk — but the right timing for you should be determined with your physician. Learn more about colonoscopy, colorectal cancer screening, and colonoscopy preparation.
Upper Endoscopy & EGD Near Fulshear
An upper endoscopy — also called an EGD (esophagogastroduodenoscopy) — lets a gastroenterologist examine the esophagus, stomach, and the first part of the small intestine (the duodenum). Fulshear-area patients can have this procedure performed through our nearby Katy office when it’s medically appropriate. Your physician may consider one to help evaluate:
- Persistent acid reflux or heartburn not responding to treatment
- Difficulty or pain with swallowing
- Ongoing upper abdominal pain or discomfort
- Persistent nausea or vomiting
- Certain concerns about upper GI bleeding
- Other suspected conditions of the esophagus or stomach
Not every patient with upper GI symptoms needs one. Learn more about upper endoscopy / EGD, endoscopy, and EGD preparation.
Gastroenterology + Hepatology
Liver Disease & Hepatology Care Near Fulshear
Fulshear-area patients who need a liver specialist can see Dr. Muhammad Ali Khan, who is board-certified in both gastroenterology and hepatology, at our nearby Katy office. Many patients are first referred because of an abnormal liver enzyme result or a fatty liver noted on imaging. Our team evaluates and manages:
- Fatty liver disease (MASLD) — from simple fat accumulation to inflammation
- Abnormal or elevated liver enzymes found on routine bloodwork
- Hepatitis and other causes of liver inflammation
- Cirrhosis and chronic liver disease
For non-invasive assessment, the practice offers FibroScan. Explore hepatology, fatty liver, and abnormal liver enzymes.

A specialized procedure to evaluate and treat conditions of the bile ducts and pancreatic ducts.
Flexible Sigmoidoscopy
Examines the lower colon and rectum to evaluate specific lower-GI symptoms.
Esophageal Dilation
Gently widens a narrowed esophagus to relieve swallowing difficulty.
Esophageal pH Monitoring

A non-invasive scan that assesses liver stiffness and fat content without a biopsy.
A Personalized Approach to Your GI Evaluation
Not every patient with the same symptom needs the same test. A thoughtful evaluation starts by understanding your specific situation before recommending any procedure. When determining the right path forward, your gastroenterologist may consider:
- Your specific symptoms and how they present
- How long you’ve had them and how severe they are
- Your overall medical history
- Medications and supplements you take
- Family history of digestive or liver conditions
- Any previous testing, imaging, or procedures
- Recent laboratory results
- Diet and lifestyle factors
- Your individual screening needs and risk factors

When should I see a gastroenterologist?
Consider seeing a gastroenterologist when digestive symptoms are persistent, recurring, or worsening — such as ongoing heartburn, abdominal pain, bloating, or changes in bowel habits — or when warning signs like blood in the stool, difficulty swallowing, or unexplained weight loss appear. An abnormal liver enzyme result is also a common reason for referral.
What conditions does a GI doctor treat?
A gastroenterologist treats conditions of the digestive tract and liver — including acid reflux and GERD, gastritis, IBS, Crohn’s disease, ulcerative colitis, constipation, chronic diarrhea, rectal bleeding, difficulty swallowing, celiac disease, gallbladder and pancreatic disorders, and liver conditions such as fatty liver disease and abnormal liver enzymes.
Where can I get a colonoscopy near Fulshear?
Fulshear-area patients can schedule a colonoscopy with United Gastroenterology Associates through the nearby Katy office. A colonoscopy is used both to screen for colorectal cancer and to evaluate symptoms like rectal bleeding or changes in bowel habits. Whether and when you need one is determined with your physician based on your age, symptoms, and risk factors.
Do you perform endoscopy for Fulshear-area patients?
Yes. Upper endoscopy (EGD) is available to Fulshear-area patients through our Katy location. An EGD examines the esophagus, stomach, and the first part of the small intestine and may be recommended for persistent reflux, difficulty swallowing, upper abdominal pain, or ongoing nausea. Your physician determines whether an endoscopy is medically appropriate for you.
Can a gastroenterologist treat acid reflux?
Yes — gastroenterologists commonly evaluate and manage acid reflux and GERD. If heartburn is frequent, disrupts sleep, or isn’t relieved by over-the-counter remedies, a specialist can determine the cause and recommend an approach, which may include dietary strategies, medication, or an upper endoscopy, depending on your symptoms.
Should I see a gastroenterologist for persistent bloating?
If bloating is frequent, ongoing, or paired with pain, changes in bowel habits, or weight loss, it’s worth seeing a gastroenterologist. Persistent bloating shouldn’t automatically be assumed to be “just gas” — it can be related to constipation, IBS, reflux, gallbladder issues, or other GI conditions, and an evaluation helps identify the cause.
What doctor treats IBS?
A gastroenterologist diagnoses and manages irritable bowel syndrome (IBS). IBS can cause cramping, bloating, and alternating diarrhea and constipation, and while there’s no single cure, it’s very manageable once properly diagnosed.
Do gastroenterologists treat fatty liver disease?
Yes. Fatty liver disease (also called MASLD) is evaluated and managed by gastroenterologists and hepatologists. Dr. Khan is board-certified in both gastroenterology and hepatology, and the practice offers non-invasive liver assessment with FibroScan. Fatty liver is often found after an abnormal liver enzyme test or an imaging finding and benefits from specialist follow-up.
Can I see a liver specialist near Fulshear?
Yes. Dr. Muhammad Ali Khan is board-certified in hepatology and sees Fulshear-area patients at the nearby Katy office. He evaluates and manages liver concerns including fatty liver disease, abnormal liver enzymes, hepatitis, and chronic liver disease, with access to non-invasive testing such as FibroScan when appropriate.
What can cause blood in the stool?
Blood in the stool can have several causes, ranging from hemorrhoids and anal fissures to inflammation, polyps, or other conditions of the colon and rectum. Because the cause isn’t always obvious, it should be evaluated by a gastroenterologist rather than assumed to be minor — an evaluation, which may include a colonoscopy when appropriate, helps identify the source.
Do I need a colonoscopy for my digestive symptoms?
Not necessarily. A colonoscopy is one of several tools a gastroenterologist may use, and whether you need one depends on your symptoms, age, history, and risk factors. Your physician recommends a colonoscopy when it will genuinely help clarify a diagnosis or when screening is due.

Yes. United Gastroenterology Associates is accepting new patients from Fulshear and the surrounding area at the nearby Katy office. To get started, call (346) 340-4414 to schedule an appointment and verify your insurance with the practice.
