Persistent Diarrhea Deserves an Appropriate Evaluation
Diarrhea can happen occasionally because of a temporary illness, dietary change, medication, or other short-term cause. However, diarrhea that continues, frequently returns, or represents a significant change from your normal bowel habits may need further evaluation.
Chronic diarrhea is not one specific disease. Instead, it is a symptom that can have many possible causes.
The right evaluation depends on several factors, including:
- How long your symptoms have been present
- How frequently diarrhea occurs
- Whether symptoms are continuous or come and go
- The appearance and consistency of your stools
- Whether you have abdominal pain or cramping
- Whether you experience bloating or increased gas
- Changes in appetite or weight
- Current medications and supplements
- Your personal medical history
- Family history of digestive conditions
A gastroenterologist for chronic diarrhea can review the complete picture and help determine whether additional testing or treatment is appropriate.
Common Gastritis Symptoms
Upper stomach pain, burning stomach pain, sour stomach, nausea, bloating after eating, indigestion, feeling full quickly, and loss of appetite are common signs of gastritis.
What Causes Gastritis?
Common causes include H. pylori infection, frequent NSAID pain relievers, alcohol, bile reflux, and autoimmune gastritis, among other digestive conditions.
When to See a GI Doctor
See a gastroenterologist if symptoms are persistent, worsening, or not improving, or if you have a history of ulcers or H. pylori or long-term NSAID use with stomach pain. Need Consultation!

What Is Chronic Diarrhea?
Diarrhea generally refers to loose, watery, or more frequent bowel movements than usual. A brief episode may occur for a temporary reason and improve on its own.
When diarrhea continues for an extended period or repeatedly returns, healthcare providers may consider further evaluation for persistent or chronic diarrhea.
There is no single symptom pattern that applies to every patient. Some people may have frequent loose stools every day, while others experience recurring episodes separated by periods of improvement.
You may consider seeing a diarrhea specialist when your symptoms:
- Continue for several weeks
- Keep returning
- Become more frequent
- Interfere with work or daily activities
- Wake you from sleep
- Occur with abdominal pain or cramping
- Occur with persistent bloating
- Are associated with unexplained weight loss
- Are accompanied by blood in the stool
- Do not have an obvious explanation
A GI evaluation can help determine whether your symptoms may be related to a functional digestive condition, inflammation, infection, medication, malabsorption, or another gastrointestinal issue.
Common Symptoms That Can Occur With Chronic Diarrhea
Chronic diarrhea may occur alone, but many patients also experience other digestive symptoms.
Frequent Loose or Watery Stools
You may notice that your stools are consistently looser than normal or that bowel movements occur more frequently than your usual pattern.
Changes that continue over time are worth discussing with a healthcare professional.
Urgent Bowel Movements
Some people experience a sudden or difficult-to-control urge to have a bowel movement. This urgency can make it challenging to work, travel, exercise, or participate in normal daily activities.
Abdominal Cramping or Pain
Cramping or abdominal discomfort may occur before or during bowel movements. In some cases, symptoms may improve after a bowel movement, while in others they may continue.
Persistent or recurring abdominal pain should be appropriately evaluated.
For more information, visit our Abdominal Pain Specialist in Cypress & Katy page.
Bloating and Increased Gas
Bloating, abdominal fullness, and increased gas can occur alongside changes in bowel movements. These symptoms may be related to several digestive conditions.
You can also learn more about Stomach Swelling & Bloating.
Fatigue or Unintended Weight Changes
Ongoing digestive symptoms can sometimes occur alongside fatigue or changes in weight. These symptoms may be important to discuss during your GI evaluation.
What Can Cause Chronic Diarrhea?
Chronic diarrhea can have a wide range of possible causes. It is important not to assume that all persistent diarrhea has the same explanation.
A gastroenterologist may consider your symptoms, history, medications, diet, and other factors when determining the appropriate evaluation.
Possible causes can include the following.
Irritable Bowel Syndrome
Some people with irritable bowel syndrome (IBS) experience diarrhea as a predominant symptom. IBS can also involve abdominal pain, bloating, and changes in bowel habits.
However, not every person with chronic diarrhea has IBS, and a diagnosis should not be assumed without appropriate evaluation.
Learn more about:
Inflammatory Bowel Disease
Inflammatory conditions affecting the digestive tract can cause symptoms such as diarrhea, abdominal pain, rectal bleeding, and changes in bowel habits.
Evaluation may be needed to determine whether inflammation or another condition is contributing to symptoms.
Learn more about Inflammatory Bowel Disease Management.
Celiac Disease
Celiac disease can affect the digestive system and may cause diarrhea, bloating, abdominal discomfort, and other symptoms in some individuals.
A gastroenterologist can determine whether testing may be appropriate based on your symptoms and medical history.
Visit our Celiac Disease Management page.
Medication-Related Diarrhea
Certain medications and supplements may contribute to diarrhea. Your GI doctor may review everything you currently take, including prescription medications, over-the-counter products, and supplements.
Do not stop prescribed medication without discussing it with the healthcare professional who manages your care.
Food-Related Digestive Symptoms
Some people notice that particular foods or dietary patterns seem to worsen digestive symptoms. Food-related symptoms can vary considerably between individuals.
A healthcare professional can help determine whether dietary factors should be considered as part of your overall evaluation.
Other Digestive and Medical Conditions
There are additional gastrointestinal and medical conditions that can cause persistent diarrhea. This is why a complete evaluation can be important when symptoms are ongoing or unexplained.
Persistent Diarrhea? See a GI Specialist
When Should You See a Diarrhea Specialist?
You do not necessarily need to see a specialist for every brief episode of diarrhea. However, recurring or persistent symptoms should not simply be ignored.
Consider scheduling a GI evaluation when you have:
Diarrhea That Keeps Returning
Recurring symptoms may indicate an ongoing issue that deserves further evaluation.
Persistent Loose Stools
A continued change from your normal bowel pattern is worth discussing with a healthcare professional.
Diarrhea With Abdominal Pain
When diarrhea occurs alongside recurring pain or cramping, a gastroenterologist can evaluate the combination of symptoms.
Diarrhea and Bloating
Persistent bloating and diarrhea can occur with multiple digestive conditions.
Unexplained Changes in Bowel Habits
A noticeable change in frequency, consistency, or urgency that persists should be evaluated appropriately.
Symptoms Affecting Daily Life
If you plan your day around access to a bathroom or avoid activities because of digestive symptoms, a GI evaluation may help identify potential causes and management options.

How Does a Gastroenterologist Evaluate Chronic Diarrhea?
Find Answers for Ongoing Diarrhea Symptoms
The evaluation begins with understanding your specific symptoms. Two people with chronic diarrhea may have very different causes, which is why an individualized approach is important.
During your appointment, your gastroenterologist may ask about:
- When diarrhea first started
- How often it occurs
- Whether symptoms happen every day
- Whether symptoms come and go
- Stool consistency and frequency
- Urgency or difficulty controlling bowel movements
- Abdominal pain or cramping
- Bloating and gas
- Nausea or vomiting
- Blood in the stool
- Weight changes
- Recent illness or travel
- Dietary changes
- Current medications
- Previous surgeries or digestive conditions
- Family history of digestive diseases
- Previous GI testing or procedures
Your answers help the doctor decide whether further testing is appropriate and which diagnostic approach may be most useful.

Acute Gastritis
Sudden stomach inflammation, often from infection, medications, alcohol, or illness.

Chronic Gastritis
Inflammation that develops slowly or keeps returning over time.

H. pylori Gastritis
Gastritis caused by Helicobacter pylori bacteria infecting the stomach lining.

Reactive & Autoimmune Gastritis
Irritation from NSAIDs, alcohol, or bile reflux, or an immune attack on the lining.

What Tests May Be Used to Evaluate Chronic Diarrhea?
Not every patient with chronic diarrhea requires the same tests.
Your symptoms, medical history, age, family history, and other risk factors can influence which tests are considered.
Depending on your individual situation, evaluation may include:
Blood Tests
Blood tests may be considered to evaluate certain medical conditions or potential effects of ongoing symptoms.
Stool Tests
Stool testing may be appropriate in certain situations to evaluate for specific causes of diarrhea.
Colonoscopy
A colonoscopy allows a gastroenterologist to examine the colon and rectum. Depending on your symptoms and risk factors, it may be recommended as part of the evaluation.
Learn more about:
Endoscopy
Depending on your symptoms, an upper GI evaluation may also be considered in selected situations.

Your gastroenterologist can explain which tests, if any, may be appropriate for your individual situation.
Chronic Diarrhea and IBS: Understanding the Difference
IBS is one possible cause of recurring changes in bowel habits, including diarrhea.
People with IBS may experience:
- Abdominal pain
- Changes in bowel habits
- Diarrhea
- Constipation
- Alternating diarrhea and constipation
- Bloating
- Increased gas
However, chronic diarrhea can occur for many reasons. Symptoms alone do not always establish an IBS diagnosis.
A GI specialist may evaluate whether your symptoms are consistent with IBS or whether another digestive condition should be considered.

Chronic Diarrhea and Rectal Bleeding
Blood in the stool or rectal bleeding should be discussed with a healthcare professional, particularly when it is persistent, recurring, or unexplained.
Diarrhea with bleeding can have several possible causes.
