The criteria of IBS diagnosis may sound complex for some IBS patients (And even to some doctors).
In this article, I will guide you to How exactly is IBS diagnosed.
This is a beginner but yet very crafted to understand the same method we (doctors) use to diagnose your IBS.
Keep reading, all your questions about IBS diagnosis will be answered here.
Is there a specific test that Diagnoses IBS?
Actually, we still have a little knowledge about what causes IBS!
So, until this moment, there is no specific blood or stool test to diagnose IBS.
IBS is classified as a “functional disorder”
What a “functional disorder” means is that we could not identify a cause of IBS using available tests (blood, stool, imaging techniques, and endoscopy).
In 2015, Dr. Mark Pimentel, MD first introduced a blood test for IBS-D diarrhea that help differentiation between IBS-Diarrhea and IBD (inflammatory bowel diseases like Crohn’s and Ulcerative Colitis).
But the test is only valid for IBS diarrhea and not specific for all types of IBS.
Additionally, it has a low sensitivity for detecting IBS diarrhea (44%) so it is not used in daily practice by doctors.
How is IBS diagnosed using Rome criteria?
In May 2016 Rome IV criteria were reintroduced as symptom-based criteria to diagnose IBS.
It is widely used and still, the most accepted way of how is IBS diagnosed.
A simplified way to diagnose yourself with Rome criteria:
|1- Onset: 6 months|
your abdominal pain started to occur for 6 months or longer.
If you started experiencing abdominal pain for a period of fewer than 6 months, it is probably not IBS.
|2- frequency of symptoms:||At least one day per week, for the last 3 months|
|3- main symptom: abdominal pain||Abdominal pain: occurs anywhere in your abdomen|
|4- abdominal pain must be associated with at least 2 of:||1- change in stool frequency: together with the onset of the abdominal pain; there may be diarrhea or constipation or alternating diarrhea and constipation.|
|2- the pain is associated with defecation: means that abdominal pain is relieved by defecation. Or increased during defecation.|
|3- the pain is associated with a change in stool form (appearance): stools become more hard or soft (even without diarrhea or constipation.|
You Can Diagnose Yourself By Asking Yourself These Questions:
1- when you first experienced abdominal pain?
If less than 6 months: Rome IV criteria not applicable (symptom onset should be 6 months or longer.
If more than 6 months: proceed to the second question.
2- in the last 3 months, can you stay for more than a week without abdominal pain?
If Yes: Rome IV criteria are not applicable (abdominal pain frequency should occur at least once a week in the last 3 months.
If No: Proceed to the next question.
3- With the onset of pain, do you experience diarrhea or constipation? (change in stool frequency).
4- With the onset of pain, does the stool become more hard or soft? (change in stool form)
5- does the abdominal pain relieved or increased during or after defecation?
For questions 3, 4, and 5 the answer must be “yes” for at least 2 of these 3 questions for IBS to be diagnosed.
How is IBS Subytypes Diagnosed?
Before we diagnose you with any IBS subtypes, we have to:
- Stop any IBS drugs that modify your IBS symptoms.
- Exclude any other drugs that cause diarrhea or constipation.
- Examples of drugs causing diarrhea:
- Nonsteroidal Anti-inflammatory drugs: Ibuprofen and Diclofenac.
- Proton pump Inhibitors: Omeprazole and Esomeprazole (Nexium).
- Digoxin (Lanoxin): a drug that is used in certain patients with heart disease
- Examples of drugs causing constipation:
- Iron preparations: used in patients with iron deficiency anemia.
- Norvasc: a drug used for hypertension and certain heart diseases.
- Some antiparkinson, anti-depressant drugs.
- Ideally, I inform my patient to keep a diary of abdominal pain and stool form for 2 weeks
- We usually use the “Bristol Stool Form Scale” to evaluate the type of IBS.
- Type 1 & 2 Bristol stool are hardest ( type 1 is separate hard lumps that are hard to pass and type 2 is lumpy sausage-shaped that is hard to pass).
- Type 6 & 7 are loosest (type 6 is Fluffy pieces with ragged edges; mushy, type 7 is watery.)
How Are IBS diarrhea, Constipation, And Mixed diagnosed? (DIY, step by step)
Here are the steps you can do to diagnose yourself with IBS diarrhea.
1- learn about the Bristol Stool Form Scale (BSFS): as we mentioned above.
2- stop IBS medications or any other medication for two weeks.
3- keep a diary of the days in which you have abdominal pain (IBS pain).
4- Record the number of your bowel habits (number of stool motions) only in the days with abdominal pain.
5- for every stool motion, also record the bristol stool form scale (1 to 7)
6- calculate the percentage of stool motions with bristol stool forms 6 and 7 of the total stool motions.
7- calculate the percentage of the number of stool motions with bristol stool form 1 & 2 of the total number of stool motions.
8- IBS-diarrhea is diagnosed when you have more than 25% of your stool motions with diarrhea (BSFS 6&7) provided that your constipation stool motions (BSFS 1&2) are less than 25% of the total number of stool motions.
Example: if you kept a diary of your abdominal pain and BSFS for 2 weeks:
- Out of the 2 weeks, there were only 9 days with abdominal pain,
- during these 9 days, you had 24 motions stool motions in total (exclude stool motions in days you don’t have abdominal pain)
- From the 24 stool motions, you have 9 motions with diarrhea (BSFS 6 or 7).
- And only 1 stool motion with constipation (BSFS 1 or 2).
- then calculate the percentage of motions with diarrhea = (9/24) X100 = 37.5% (more than 25).
- And calculate the percentage of motions with constipation (2/24) X100 = 8.3% (Less than 25%)
- So this is diarrhea-predominant IBS.
9- IBS-constipation is diagnosed when the opposite occurs (more than 25% are constipation and less than 25% are diarrhea).
10- IBS-Mixed is diagnosed when both constipation and diarrhea are more than 25% of the total stool motions.
11- IBS-Unclassified is diagnosed when both constipation and diarrhea-predominant motions are less than 25% of the total stool motions during days of abdominal pain.
Can Rome Criteria Be wrong?
The Rome criteria are developed mainly To “HELP” in the diagnosis of IBS. so it is not the ultimate truth about the presence of IBS.
We -doctors- still judge every patient on an individual basis, and this is according to the Rome criteria itself. (see screenshot below from Rome criteria publication):
And here is why:
1- basically when we (doctors) develop symptom-based criteria for a diagnosis of a disease, this means we yet don’t fully understand this disease.
2- the symptom Based criteria in Rome IV (abdominal pain and its association with mealtime, change in stool form or frequency) actually occur in a wide variety of other diseases inside your gut like:
- Food sensitivities (diet intolerance)
- Inflammatory bowel diseases.
- Bile acid malabsorption.
- Celiac disease
- Colon cancer
- Post-infectious malabsorption (tropical sprue)
- SIBO (small intestinal bacterial overgrowth).
- GERD (Gastro-Esophageal Reflux Disease).
Although these above-listed diseases have more reliable methods of diagnosis, they always get confused with IBS.
My advice to you is to always ask your doctor about your symptoms if you’re not sure about your symptoms.
3- New onset IBS (less than 6 months) is not included in Rome criteria.
4- Rome criteria are not applied alone, we (doctors) may need to ask some other questions or do some tests to confirm a diagnosis of IBS.
These questions and tests are directed mainly to exclude other diseases that may resemble IBS.
The tests and questions are different for every patient according to its age, sex, existing diseases, and his specific complaints.
So, Rome Criteria are a great tool to “Approach” the truth, but it is not the truth about IBS”
When we suspect that you may don’t have IBS? (Red Flags):
1- A family history of colorectal cancer:
If one of your family members has a history of colorectal cancer you should take your gut symptoms more seriously.
Colon cancer symptoms may resemble IBS. so you have to consult your doctor about any gut pain or abnormal stool or blood in the stool.
I this article I’ve thoroughly discussed how to know the difference between IBS and colon cancer.
2- A passage of blood with stool:
Blood in stool is not a symptom of IBS, the commonest cause of bloody stool with IBS is piles, anal fissure, but also inflammatory bowel diseases like ulcerative colitis or even colon cancer may be the cause of your blood in the stool
My advice to you: first, plan an appointment with your doctor, second, you can read this article that enlists all the causes of blood in stool with IBS.
3- weight loss:
Weight loss usually doesn’t occur with IBS. presence of significant weight loss together with abdominal pain is common with conditions like:
- Inflammatory Bowel diseases (Crohn’s and ulcerative colitis)
- Colon cancer (or any other cancer).
- Malabsorption syndrome.
- Some rare infections like abdominal tuberculosis.
- Or it could be simply due to dietary habits (if you are eating less)
The bottom line is that you have to define the cause of weight loss with your doctor.
Anemia may indicate blood loss (even unnoticed) or other diseases like celiac disease. Discuss the issue with your doctor.
How doctors diagnose you with IBS (the complete steps I take):
The complete process of diagnosing IBS includes:
1- taking accurate history, and if needed planning follow-up visits to establish the diagnosis.
2- perform a thorough clinical examination.
3- perform limited tests in selected patients (including colonoscopy).
1- Taking An Accurate History, And If Needed Planning Follow-up Visits To Establish The Diagnosis.
- First I ask the history of abdominal pain and associated symptoms (applying Rome IV criteria).
- I ask for alarm features (family history of colon cancer, family history of IBD, blood in the stool, anemia, weight loss, late onset of the IBS after the age of 50)
- I Take detailed dietary history especially the intake of dairy products.
- I ask about any drug history especially drugs causing constipation or diarrhea or gut upset.
- I may need a follow-up visit if the diagnosis is unclear (especially for detecting the subtype of IBS).
2- Perform a thorough clinical examination.
- We usually don’t find remarkable signs for IBS, but the main aim is to exclude other diseases.
- In patients with IBS Constipation, we may need to perform a Digital Rectal examination to exclude hemorrhoids and fissures.
3- Perform limited tests in selected patients.
When we perform tests for IBS:
- Have one or more of the alarm features
- For patients with IBS diarrhea testing for infectious diarrhea, IBS, and celiac disease is performed.
- If you are older than 50 or have blood in stool or weight loss, we may consider colonoscopy.
- If you have severe constipation we may need to perform some abdominal radiograph and some tests like anorectal manometry.
Are there other methods of IBS diagnosis?
Yes, the Manning criteria and another rarely used criteria called “Kruis”
The manning criteria include:
- Pain relieved with defecation
- More frequent stools at the onset of pain
- Looser stools at the onset of pain
- Visible abdominal distention
- Passage of mucus
- A sensation of incomplete evacuation.
The more criteria it presents, the more the likelihood of IBS.
But the Manning and the Kruis criteria didn’t perform well in the diagnosis of IBS (compared to Rome criteria).
So Rome criteria are considered the cornerstone for the diagnosis of IBS.
- No specific and reliable test is available for IBS diagnosis.
- “Rome criteria” is the most widely used criteria for IBS diagnosis, it is a symptom-based criteria.
- Other criteria exist for IBS diagnoses like the manning criteria and the Kruis criteria, but they’re less accurate.
- Rome criteria are only to guide diagnosis, We (doctors) may find some patients not matching the Rome criteria and still need IBS treatments.
- The diagnosis of IBS is individualized for every patient by the doctor.
- This article is a guide to simplify the process of how is IBS diagnosed, you have to consult your doctor before the final IBS diagnosis.
h. pylroi is linked to many skin diseases such as chronic spontanous urticaria, psoriasis, rosacea, rash, and hives.
The h. pylroi poop often has no specifc look. But if you have h. pylori-induced bleeding ulcer, you may experience black poop. Diarrhea and constipation are also linked to H. pylroi.
Possible foods that can kill H. pylori Naturally include Lactoferrin, Honey, Probiotic foods, some oils, fatty acids, Isothiocyanates, and phenolic drivatives.
Constant Nausea and burping commonly occur due to EGRD, Gastritis, and Peptic ulcer disease. However, other causes include pregnancy, functional dyspepsia, food intolerance, gallbladder diseases, esophageal motility disorders, gastroparesis, medications, and kidney failure.
Common causes of non-healing stomach ulcers include h. pylori persistence, non-response to PPIs, smoking, big ulcer size, medications (NSAIDs), etc.
Common causes of pain in the middle of your stomach above the belly button are gastritis, peptic ulcer disease, or functional dyspepsia. Other causes include pancreatitis, gallbladder diseases, colon pain, and cancers.
The link between bloating and pantoprazole is not clear. Short-term PPI (as pantoprazole) for a week or two is unlikely to cause bloating. However, studies show that long-term pantoprazole (for 8 weeks or longer) is linked to increased risks of bloating.
Taking pantoprazole first thing in the morning is more effective. Stomach acid is highest in the morning, which leads to more activation of pantoprazole. In addition, morning pantoprazole inhibits more H-K-ATPase enzymes (leading to more acid suppression).
You can drink coffee 30-60 minutes after taking omeprazole. However, You should note that coffee may worsen your stomach symptoms. Decaffeinated coffee is a good option.
omeprazole long-term side effects include infections (as C. difficile), vitamin and mineral deficiency, kidney diseases, lupus, and others.
