Other tests that you may encounter while in the process of being diagnosed include:
You might be required to have blood tests to rule out disorders like celiac or inflammatory bowel disease, which can have very similar symptoms to IBS.
Colonoscopies are used to examine the colon and determine if an inflammatory condition or cancerous growth might be responsible for the IBS-like symptoms.
Parasites like giardia can lead to stomach cramps, bloating, and diarrheasimilar symptoms to IBS.
CT scans and X-rays can be used to rule out other conditions that might be causing abdominal pain.
Stool tests and examinations
Fecal tests are commonly undertaken when figuring out if a patient has IBS. These tests can help rule out other conditions that can mimic the symptoms of IBS.
Food allergy tests
Sensitivity or allergies to foods or food intolerances, such as lactose or gluten intolerance, should be evaluated because they can cause symptoms similar to IBS.
Breath tests can be used to determine if you have other issues that might be causing your symptoms, like bacterial overgrowth in the small intestine or lactose intolerance.
An upper endoscopy involves placing a tube with a camera on the end down the throat and into the stomach and small intestine, where samples can be taken to test for conditions like acid reflux, bacterial overgrowth, or celiac disease¹.

Key Lab Tests Diagnosis Of Ibs
Are you looking to learn more about the key lab tests that are used for IBS diagnosis? Heres everything you need to know:
CRP, also known as the C-Reactive Protein test, is a blood test that measures the amount of inflammation thats found in the body. This protein is created in the liver, and higher quantities of CRP are produced when the body is responding to inflammation.
In a healthy body, there arent any C-Reactive Protein markers measured in the blood. However, in people with IBS or Celiac Disease, there CRP can be detected in the blood.
ESR stands for Erythrocyte Sedimentation Rate, which is a type of blood test that measures how quickly your red blood cells fall to the bottom of a test tube that contains your blood sample. In healthy patients, the erythrocytes slowly settle to the bottom of a test tube.
When red blood cells fall to the bottom of a test tube quickly, its an indicator that theres inflammation in your body. An ESR test can help doctors determine if you have a condition that causes inflammation, such as IBS. ESR tests are not only used to diagnose someone with IBS but can also help medical professionals monitor your health condition during treatment.
If your doctor suspects that you have IBS, a complete blood count test must be completed. A CBC can help confirm this autoimmune condition if the main symptom that youre experiencing is diarrhea, which is an indication that you may have IBS-D.
Ibs Causes And Risk Factors
While several things are known to trigger IBS symptoms, experts don’t know what causes the condition.
Studies suggest that the colon gets hypersensitive, overreacting to mild stimulation. Instead of slow, rhythmic muscle movements, the bowel muscles spasm. That can cause diarrhea or constipation.
Another theory suggests it may involve chemicals made by the body, such as serotonin and gastrin, that control nerve signals between the brain and digestive tract.
Other researchers are studying to see if certain bacteria in the bowels can lead to the condition.
IBS affects between 25 million and 45 million Americans. Some things seem to make people more likely to have it than others:

Ibs Types And Symptoms
It is important to determine subtype as IBS treatment recommendations vary based on subtype. There are medications specifically designed for treatment of IBS-C and IBS-D , although not for IBS-M .
IBS subtype may also change over time, so its important for you and your doctors to keep track of stool form and frequency changes.
Doctors will use the Rome IV Criterias Bristol Stool Scale to help determine the type of IBS that you have. There are 7 different types of stool on the Bristol Stool Scale:
- If over 25% of bowel movements are type 1 or 2 and less than 25% are type 6 or 7, its IBS-C
- If over 25% of bowel movements are type 6 or 7 and less than 25% are type 1 or 2, its IBS-D
- If over 25% of bowel movements are type 1 or 2 AND over 25% are type 6 or 7, its IBS-M
- If none of the above, IBS-U
In addition to reviewing your symptoms, your doctor will also ask about your family history.

How Is Ibs Diagnosed By A Doctor
To diagnose IBS, your doctor will primarily ask you about your symptoms and their frequency. It can be hard for some people to talk about GI problems with their doctor, but being open and honest with your physician is the best way for them to diagnose your symptoms and make a treatment plan that works for you.
Your doctor may ask questions like:
- What kinds of gastrointestinal symptoms are you experiencing?
- How frequently do you experience symptoms? Do they come and go, or do they happen almost every day?
- Are symptoms triggered by certain foods?
- Do you notice symptoms appearing during or after times of stress?
- Do you have a family history of IBS or other gastrointestinal conditions?
Currently, there are no laboratory tests that can diagnose IBS. However, your doctor may recommend you receive certain tests in order to rule out other possible causes for your symptoms.
Doctors diagnose IBS based on your history of symptoms and a lack of evidence of other conditions. If youre concerned that your abdominal pain may be IBS, talk to your doctor.
When Should I See A Healthcare Provider
See your provider if you have symptoms more than three times a month for more than three months. And if you have symptoms less often, but they interfere with your life, its a good idea to talk to your provider.
Some symptoms may point to a more serious problem. Contact your provider as soon as possible if you have:

Are There Complications Of Irritable Bowel Syndrome
While IBS can be painful, it is reassuring to remember that the condition does not cause long-term damage to the colon or other parts of the digestive system. IBS also does not directly cause other physical health problems.
Although IBS is often a mild condition that can be well-managed by diet and other lifestyle improvements, it can significantly impact some people’s quality of life, and can be stressful to manage. Flow-on effects can include depression and anxiety, migraine, fibromyalgia and/or chronic fatigue syndrome.
If IBS is causing you to feel down, anxious or upset, there are IBS-specific psychological support services. Talk to your GP about whether they are right for you.
A small number of people with IBS may experience faecal incontinence. The Continence Foundation of Australia can help with strategies where this is due to constipation or diarrhoea. Call their toll-free helpline for advice on 1800 330066.
Physical Exam And Blood Test
A diagnosis of IBS begins with a comprehensive physical exam during which you describe your symptoms and medical history. Your doctor may diagnose IBS based on your symptoms and history, but will also look for red flags that suggest the need to look for a different diagnosis. Red flags include:
- Onset of symptoms in someone who is more than 50 years of age.
- Unexplained weight loss.
- Evidence of gastrointestinal bleeding.
- Pain or other symptoms that awaken you in the middle of the night.
If you have symptoms of IBS and a red flag symptom, you will probably need a more complete investigation. You may require further testing, depending on what your symptoms are.

Ibs Can Be Quickly Diagnosed With New Blood Test
Irritable bowel syndrome, the most common gastroenterological disorder in the US, can now be diagnosed with just two simple blood tests, enabling early diagnosis for millions of people affected by the disorder.
Until now, irritable bowel syndrome has only been diagnosed after a long and drawn out process of ruling out other conditions, often involving invasive procedures such as colonoscopies and sigmoidoscopies.
Dr. Mark Pimentel, a gastroenterologist at Cedars-Sinai in Los Angeles, CA, created the tests. He explains that as there have been no definitive tests for IBS, patients have frequently had to go from doctor to doctor, repeating tests before they have been able to get a diagnosis they are confident with.
Having an early diagnosis means patients can avoid years of invasive tests and visits to specialists that often leave them with more questions than answers, he explains. With these new blood tests, many patients will now be able to proceed right to therapy for their condition.
Around 10% of the global population is estimated to have IBS, with around 10-15% of the US population affected. The condition is characterized by a variety of symptoms that includes abdominal pain, bloating and bouts of diarrhea and constipation that can cause stress and fatigue.

The symptoms of IBS can vary from person to person. Some people have IBS with constipation, which means they have hard, dry stools that are difficult to pass. Other people have IBS with diarrhea, which means they have loose, watery stools.
Some people have IBS with alternatingconstipation and diarrhea. And some people have IBS with other symptoms, such as abdominal pain, bloating, and gas.
IBS is a diagnosis of exclusion, which means that other conditions must be ruled out before a diagnosis can be made. IBS cannot be diagnosed through a blood test or imaging test. Instead, the diagnosis is made based on the symptoms. If you have IBS, its important to talk to your doctor about the best way to manage your symptoms.
