What Is IBS?
IBS stands for irritable bowel syndrome, a condition involving recurring abdominal symptoms and changes in bowel habits.
Symptoms can vary significantly from one person to another.
Common symptoms associated with IBS may include:
- Abdominal pain or discomfort
- Abdominal cramping
- Bloating
- Increased gas
- Diarrhea
- Constipation
- Alternating diarrhea and constipation
- Changes in stool frequency
- Changes in stool consistency
IBS symptoms can overlap with symptoms caused by other digestive conditions. For this reason, an appropriate medical evaluation may be important, particularly when symptoms are new, persistent, or changing.

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?

When to See a GI Doctor

When Should You See an IBS Specialist?
You may consider seeing an IBS specialist or gastroenterologist when digestive symptoms are persistent, recurring, or affecting your quality of life.
A GI evaluation may be appropriate if you experience:
- Recurring abdominal pain
- Ongoing bloating
- Persistent diarrhea
- Frequent constipation
- Alternating diarrhea and constipation
- Unexplained changes in bowel habits
- Symptoms that interfere with work, sleep, or daily activities
- Symptoms that continue despite previous treatment
Because IBS symptoms can overlap with other digestive conditions, a gastroenterologist can evaluate your symptoms and determine whether further testing is appropriate.
Common Symptoms of IBS
IBS can affect people differently.
Some patients primarily experience abdominal pain and constipation, while others experience diarrhea or alternating bowel patterns.
Symptoms may include:
Abdominal Pain and Cramping
Abdominal pain or cramping is a common reason patients seek evaluation. Symptoms may occur with changes in bowel movements or improve after a bowel movement in some individuals.
For persistent pain, visit our Abdominal Pain Specialist page.
Bloating and Gas
Many patients with IBS experience bloating, abdominal fullness, or increased gas.
Learn more about IBS Gas and Bloating Treatment.
Diarrhea
Some patients experience frequent or urgent bowel movements.
Persistent diarrhea should be evaluated because it can have multiple possible causes.
Constipation
Other patients experience infrequent bowel movements, difficulty passing stool, or other constipation symptoms.
Visit our Constipation page for related information.
Types of IBS
IBS may be described based on the patient's predominant bowel pattern.
IBS With Constipation (IBS-C)
IBS-C may involve abdominal discomfort along with constipation-related symptoms.
IBS With Diarrhea (IBS-D)
IBS-D may involve abdominal discomfort with frequent or loose bowel movements.
Mixed IBS (IBS-M)
Some patients experience alternating constipation and diarrhea.
Symptoms and treatment needs vary. A gastroenterologist can evaluate your individual symptom pattern.

How an IBS Specialist Evaluates Your Symptoms
IBS does not have one single test that confirms the diagnosis in every patient.
A gastroenterologist may review:
- Your symptoms
- How long symptoms have been present
- The location and pattern of abdominal pain
- Bowel movement frequency
- Stool consistency
- Bloating and gas
- Dietary patterns
- Medication use
- Personal medical history
- Family history
- Previous testing
- Other symptoms that may require additional evaluation
The goal is to understand your symptoms and determine whether IBS or another digestive condition may be contributing.
