Persistent Stomach Pain: Common Causes, Diagnostic Tests and When to See a Gastroenterologist

Occasional stomach discomfort can happen after a heavy meal, indigestion, stress or a temporary stomach infection. But when stomach pain keeps coming back, lasts for several days, becomes more frequent, or starts affecting your appetite and daily routine, it deserves closer attention.

Persistent stomach pain does not point to one specific disease. The discomfort may come from the stomach itself, the intestines, gallbladder, liver, pancreas, urinary system or other structures inside the abdomen. The location, duration, severity and accompanying symptoms can provide useful clues, but they cannot establish a diagnosis on their own.

Common digestive conditions associated with abdominal discomfort include acid reflux, gastritis, peptic ulcers, irritable bowel syndrome, infections, gallbladder problems and other gastrointestinal disorders. In some cases, the cause may be outside the digestive system altogether.

If you have ongoing or unexplained symptoms, a medical evaluation can help determine whether you need simple treatment, laboratory testing, imaging or specialist care.

For people looking for digestive healthcare, Gastroenterology care covers conditions affecting the stomach, intestines, liver, gallbladder, pancreas and other parts of the digestive system.

What Is Persistent Stomach Pain?

The words “stomach pain” are commonly used to describe discomfort anywhere in the abdomen. Medically, abdominal pain can occur in different areas and can feel sharp, burning, cramping, dull, aching or severe.

Pain may:

  • Remain constant
  • Come and go
  • Become worse after eating
  • Occur mainly at night
  • Improve after passing stool or gas
  • Be associated with bloating or indigestion
  • Spread toward the back or another part of the body

The duration is also important. Acute abdominal pain can develop suddenly and last hours or days, while chronic or persistent abdominal pain may continue or recur over a longer period.

That is why simply taking an antacid or painkiller repeatedly without understanding the underlying cause may not be the best approach.

Common Causes of Persistent Stomach Pain

There are many possible stomach pain causes, ranging from relatively common digestive problems to conditions that require urgent medical attention.

1. Indigestion and Functional Dyspepsia

Indigestion, also called dyspepsia, can cause discomfort or burning in the upper abdomen. Some people also experience early fullness, bloating, belching or nausea.

When testing does not identify an underlying structural disease, doctors may consider a condition called functional dyspepsia. The appropriate evaluation depends on age, symptoms, medical history and risk factors.

2. Gastritis

Gastritis refers to inflammation of the stomach lining.

Possible symptoms include:

  • Upper abdominal discomfort
  • Nausea
  • Feeling full quickly
  • Indigestion
  • Loss of appetite
  • Vomiting in some cases

The causes can vary. Certain medicines, infections such as H. pylori, alcohol and other factors can contribute to stomach-lining inflammation.

Treatment depends on the underlying cause rather than simply treating the pain.

3. Acid Reflux and GERD

Acid reflux occurs when stomach contents move upward toward the oesophagus.

Repeated reflux may cause:

  • Heartburn
  • Sour or acidic taste
  • Upper abdominal discomfort
  • Chest discomfort
  • Regurgitation
  • Difficulty swallowing in some cases

If heartburn or reflux occurs frequently or does not improve with appropriate measures, a doctor may need to determine whether GERD or another digestive condition is responsible.

You can also explore Siris Healthcare's information on GERD and acid reflux care as part of its gastroenterology resources.

4. Peptic Ulcers

A peptic ulcer is a sore that develops in the lining of the stomach or the first part of the small intestine.

Some people experience:

  • Burning or aching upper abdominal pain
  • Pain between meals
  • Night-time discomfort
  • Nausea
  • Bloating
  • Indigestion

H. pylori infection and certain medicines are among the possible causes.

Persistent or recurrent symptoms should be assessed rather than assuming they are simply acidity.

5. Irritable Bowel Syndrome

Irritable bowel syndrome (IBS) is a functional gastrointestinal disorder that can cause abdominal pain together with changes in bowel habits.

Symptoms may include:

  • Abdominal cramps
  • Bloating
  • Constipation
  • Diarrhoea
  • Alternating constipation and diarrhoea
  • Changes in bowel movements

IBS is diagnosed based on symptoms and medical assessment, while other conditions may need to be excluded depending on the individual's presentation.

6. Gallbladder Problems

The gallbladder stores bile, which helps digest fats. Problems such as gallstones can cause abdominal pain, particularly in the upper-right or upper-middle abdomen.

Pain related to gallbladder problems may occur after meals and can sometimes spread toward the back or shoulder.

Other symptoms may include nausea or vomiting.

7. Pancreatic Conditions

The pancreas is located behind the stomach and plays an important role in digestion and blood-sugar regulation.

Some pancreatic conditions can cause upper abdominal pain, sometimes extending toward the back. Pancreatitis, for example, can cause upper abdominal pain accompanied by nausea, vomiting, fever or abdominal tenderness.

Pain with this pattern requires medical assessment rather than prolonged self-treatment.

8. Gastrointestinal Infections

Stomach and intestinal infections may cause abdominal cramps together with:

  • Diarrhoea
  • Vomiting
  • Fever
  • Nausea
  • Weakness
  • Dehydration

Most short-term infections improve with appropriate supportive care, but persistent symptoms, severe dehydration or blood in the stool require medical evaluation.

9. Constipation and Bowel Disorders

Constipation can cause abdominal discomfort, bloating and a feeling of incomplete bowel emptying.

However, persistent constipation accompanied by significant pain, vomiting, abdominal swelling or inability to pass stool or gas should not simply be treated at home.

10. Urinary or Kidney-Related Conditions

Not every case of abdominal pain originates in the digestive system.

Kidney stones and urinary conditions can sometimes produce pain in the side, lower abdomen or groin. Changes in urination or blood in the urine may provide additional clues.

When symptoms suggest a urinary or kidney-related cause, a Urology specialist or Nephrology specialist may be involved depending on the problem.

Where You Feel the Pain Can Provide Clues

The location of abdominal pain can help doctors narrow down possible causes, although it cannot diagnose a condition by itself.

Upper Abdominal Pain

Possible causes can include:

  • Gastritis
  • Acid reflux
  • Peptic ulcer disease
  • Gallbladder conditions
  • Pancreatic disorders
  • Other gastrointestinal conditions

Lower Abdominal Pain

Possible causes include:

  • Constipation
  • IBS
  • Intestinal disorders
  • Urinary conditions
  • Appendicitis
  • Reproductive-system conditions in women

Right-Sided Abdominal Pain

Depending on the location and symptoms, doctors may consider conditions involving the appendix, gallbladder, liver, intestines or urinary system.

Pain That Travels to the Back

Upper abdominal pain extending toward the back can occur with some pancreatic conditions and other disorders. It should be assessed particularly when the pain is sudden, severe or accompanied by vomiting or fever.

When Should You See a Gastroenterologist?

You do not necessarily need a gastroenterologist for every episode of stomach discomfort.

However, consider professional evaluation if you have persistent stomach pain or recurring symptoms such as:

  • Repeated abdominal pain
  • Frequent acidity or heartburn
  • Persistent indigestion
  • Recurrent bloating
  • Long-lasting constipation or diarrhoea
  • Significant changes in bowel habits
  • Difficulty swallowing
  • Recurrent vomiting
  • Blood in the stool
  • Black or tarry stools
  • Unexplained weight loss
  • Persistent loss of appetite
  • Unexplained anaemia
  • Jaundice
  • Abnormal liver-function tests
  • Recurrent symptoms despite treatment

Siris Healthcare's Gastroenterology guidance similarly identifies persistent abdominal pain, reflux, bloating, bowel changes, blood in the stool, unexplained weight loss and liver or gallbladder symptoms as reasons to consider specialist evaluation.

When Is Stomach Pain an Emergency?

Some abdominal symptoms should not wait for a routine specialist appointment.

Seek urgent medical attention if stomach or abdominal pain is:

  • Sudden and severe
  • Getting rapidly worse
  • Associated with fainting or severe dizziness
  • Accompanied by vomiting blood
  • Associated with black or bloody stools
  • Accompanied by persistent vomiting
  • Associated with high fever
  • Accompanied by severe abdominal swelling or tenderness
  • Associated with chest pain or difficulty breathing
  • Following significant trauma or injury

Severe abdominal pain with these symptoms can sometimes indicate a condition requiring immediate assessment.

For emergencies, patients should seek immediate emergency medical care rather than waiting for a gastroenterology appointment.

Siris Healthcare also provides information about Emergency Medicine and Emergency Care for patients who need urgent medical evaluation.

How Is Persistent Stomach Pain Diagnosed?

There is no single stomach pain diagnostic test that works for everyone.

The right investigation depends on:

  • Where the pain occurs
  • How long it has been present
  • Whether it is related to food
  • Other symptoms
  • Age
  • Existing medical conditions
  • Medication use
  • Family history
  • Findings from the physical examination

A doctor usually begins with a detailed history and physical examination before deciding which tests are appropriate.

1. Blood Tests

Blood tests may be used to look for signs of:

  • Anaemia
  • Infection
  • Inflammation
  • Liver abnormalities
  • Pancreatic problems
  • Other systemic conditions

Not every patient with stomach pain needs every blood test.

2. Stool Tests

Depending on symptoms, stool testing may help investigate:

  • Certain gastrointestinal infections
  • Intestinal inflammation
  • Gastrointestinal bleeding
  • Other bowel-related conditions

3. Abdominal Ultrasound

An abdominal ultrasound uses sound waves to create images of internal organs.

It can be useful for evaluating structures such as:

  • Gallbladder
  • Liver
  • Bile ducts
  • Pancreas
  • Kidneys
  • Other abdominal structures

The choice of imaging depends on what the doctor is trying to investigate.

4. CT Scan

A CT scan creates detailed cross-sectional images of the body.

It may be considered when doctors need more detailed information about abdominal organs, inflammation, infection, obstruction, trauma or other conditions.

Siris Healthcare's Diagnostics service describes CT, MRI, ultrasound and X-ray as available diagnostic imaging modalities across its network.

5. MRI

An MRI can provide detailed images of soft tissues and may be appropriate for selected abdominal, liver, biliary or pancreatic problems.

It is not automatically required for every person with stomach pain.

6. Upper GI Endoscopy

An upper GI endoscopy, sometimes called gastroscopy, allows a doctor to directly examine the lining of the oesophagus, stomach and first part of the small intestine using a flexible camera.

Depending on the clinical situation, endoscopy may help investigate:

  • Persistent upper abdominal symptoms
  • Difficulty swallowing
  • Gastrointestinal bleeding
  • Certain reflux-related problems
  • Suspected ulcers
  • Other upper gastrointestinal conditions

The decision to perform an endoscopy depends on the patient's symptoms, age, risk factors and clinical assessment.

You can learn more about Upper GI Endoscopy and gastroenterology care through Siris Healthcare's gastroenterology resource.

7. Colonoscopy

A colonoscopy examines the large intestine and rectum.

Doctors may recommend it for selected symptoms such as:

  • Rectal bleeding
  • Persistent bowel changes
  • Unexplained anaemia
  • Certain chronic bowel symptoms
  • Colorectal cancer screening when appropriate

Not everyone with abdominal pain requires a colonoscopy.

Why You Should Not Order Tests Without Medical Advice

It can be tempting to search online for the “best scan for stomach pain” and book multiple tests independently.

That approach can create two problems.

First, different conditions can produce similar symptoms. Second, an imaging test may not answer the actual clinical question.

For example, persistent upper abdominal discomfort might require a different evaluation from lower abdominal pain associated with bowel changes.

A better approach is:

Symptoms → Clinical evaluation → Appropriate tests → Diagnosis → Treatment

The Siris Healthcare Diagnostics page similarly describes diagnostic care as a process beginning with consultation, followed by the appropriate sample or scan, analysis and follow-up.

What Happens During a Gastroenterology Consultation?

A gastroenterologist for stomach pain will usually begin by asking detailed questions about your symptoms.

Your doctor may ask:

  • Where exactly does the pain occur?
  • When did it start?
  • Is it constant or intermittent?
  • Does food make it better or worse?
  • Does it occur at night?
  • Do you have heartburn or acidity?
  • Have your bowel habits changed?
  • Are you constipated or having diarrhoea?
  • Have you noticed blood in your stool?
  • Have you lost weight without trying?
  • Are you vomiting?
  • What medicines and supplements do you take?
  • Have you previously had digestive problems?

The doctor may then perform a physical examination and decide whether blood tests, stool tests, imaging, endoscopy or another investigation is appropriate.

How to Prepare for a Gastroenterology Appointment

You can make the consultation more useful by preparing a few details beforehand.

Bring previous medical reports

Carry relevant:

  • Blood-test reports
  • Ultrasound reports
  • CT or MRI reports
  • Endoscopy reports
  • Previous prescriptions
  • Hospital discharge summaries

Make a medication list

Include prescription medicines, over-the-counter medicines and supplements.

Track your symptoms

For several days, note:

  • When the pain occurs
  • Where it occurs
  • What you ate before it started
  • Pain intensity
  • Bowel movements
  • Nausea or vomiting
  • Heartburn
  • Any fever or weight change

This information can help the doctor identify patterns.

Other Specialists Who May Be Involved

Although a gastroenterologist is often appropriate for persistent digestive symptoms, abdominal pain can sometimes involve other organ systems.

Depending on the symptoms, doctors may involve:

This does not mean persistent stomach pain is usually caused by a serious disease. It means abdominal symptoms can have many different causes, so the correct specialist and diagnostic pathway depend on the individual presentation.

What You Can Do While Waiting for an Appointment

If your symptoms are mild and you are waiting for a medical consultation, some general measures may help:

  • Stay adequately hydrated.
  • Eat smaller meals if large meals worsen discomfort.
  • Keep track of foods that consistently trigger symptoms.
  • Avoid excessive alcohol.
  • Do not repeatedly self-medicate without professional advice.
  • Follow prescribed medicines as directed.
  • Keep previous medical reports available.

These measures are not a substitute for diagnosis, particularly when pain is persistent or worsening.

Frequently Asked Questions

1. What are the most common causes of persistent stomach pain?

Common causes can include indigestion, gastritis, acid reflux, peptic ulcers, IBS, constipation, gastrointestinal infections and gallbladder problems. Other conditions involving the pancreas, urinary system or other organs can also cause abdominal pain.

2. When should I see a gastroenterologist for stomach pain?

Consider seeing a gastroenterologist if your stomach pain keeps returning, does not improve, or occurs with persistent indigestion, reflux, bowel changes, unexplained weight loss, blood in the stool, difficulty swallowing or other concerning symptoms.

3. What tests are used to diagnose stomach pain?

Depending on the symptoms, doctors may recommend blood tests, stool tests, abdominal ultrasound, CT, MRI, upper GI endoscopy or colonoscopy. The appropriate test depends on the suspected cause.

4. Is endoscopy necessary for stomach pain?

No. Endoscopy is not required for every patient with stomach pain. A doctor decides whether it is appropriate based on symptoms, age, risk factors, medical history and other findings.

5. Can acidity cause persistent stomach pain?

Acid reflux, GERD, gastritis and other upper gastrointestinal conditions can cause recurring discomfort or burning. However, persistent symptoms should not automatically be assumed to be “just acidity.”

6. When is abdominal pain an emergency?

Severe or sudden abdominal pain, vomiting blood, black or bloody stools, persistent vomiting, high fever, severe abdominal tenderness or swelling, fainting, breathing difficulty or associated chest pain can require urgent medical assessment.

7. Which doctor should I see for chronic abdominal pain?

A general physician or internal medicine doctor can initially evaluate many types of abdominal pain. A gastroenterologist may be appropriate when symptoms suggest a digestive-system problem or when specialist investigation is needed.

8. Can stomach pain come from the kidneys or urinary system?

Yes. Kidney stones and other urinary conditions can cause pain in the side, abdomen or groin. Urinary symptoms or blood in the urine can provide additional clues, and medical evaluation can determine whether urology or nephrology care is appropriate.

Final Takeaway

Persistent stomach pain should not be ignored, but it also does not automatically mean that something serious is wrong.

Digestive problems such as indigestion, gastritis, reflux, ulcers and IBS are among the possible explanations, while gallbladder, pancreatic, urinary and other conditions can also produce abdominal discomfort.

The most useful clues are where the pain occurs, how long it has lasted, what triggers it, whether it is getting worse and what other symptoms occur alongside it.

If your symptoms are persistent, recurrent or unexplained, speaking with a qualified healthcare professional can help determine whether you need laboratory testing, imaging, endoscopy or specialist care.

For patients seeking digestive healthcare in Hyderabad, Medicover Hospitals, Financial District provides access to gastroenterology and related multidisciplinary services listed on its Siris Healthcare hospital profile.

If you have severe abdominal pain, vomiting blood, black or bloody stools, fainting, severe swelling, difficulty breathing or another emergency warning sign, seek urgent medical care rather than waiting for a routine appointment.
