Irritable Bowel Syndrome (IBS) Blood Test

What is Irritable Bowel Syndrome (IBS)?

Irritable Bowel Syndrome (IBS) is a functional gastrointestinal disorder characterized by chronic abdominal pain, bloating, and changes in bowel habits. It is caused by disrupted gut-brain communication, intestinal inflammation, and food sensitivities that trigger immune responses. The Food Specific IgG test is the most important test for identifying dietary triggers that exacerbate IBS symptoms.

What causes IBS?

IBS is caused by a combination of factors including disrupted communication between the brain and gut, intestinal inflammation, altered gut motility, and food sensitivities. Specific triggers include elevated IgG antibodies to foods like buckwheat, lima beans, dairy, and gluten that provoke immune responses in the digestive tract. Stress, hormonal changes, and imbalances in gut bacteria also contribute to symptom flare-ups, creating a cycle of abdominal pain, bloating, and irregular bowel movements.

What is the best test for IBS?

The Food Specific IgG test is the most important test for IBS because it identifies specific foods triggering your immune system and worsening digestive symptoms. Tests like Food Specific IgG Buckwheat and Food Specific IgG Lima Bean measure antibody levels to common trigger foods, helping you pinpoint dietary culprits causing abdominal pain, bloating, and bowel changes. While IBS is diagnosed clinically based on symptoms, IgG testing provides actionable data to guide elimination diets and personalize your treatment plan, often leading to significant symptom improvement when trigger foods are removed.

When should I get tested for IBS?

You should get tested if you experience chronic abdominal pain or cramping at least one day per week for three months, along with changes in bowel frequency or stool consistency. Other signs include persistent bloating that worsens after meals, mucus in your stool, or symptoms that improve after bowel movements. Testing is especially important if you suspect certain foods trigger your symptoms, if over-the-counter treatments have not helped, or if your symptoms interfere with your daily activities and quality of life.

What are the symptoms of IBS?
IBS symptoms include recurrent abdominal pain or cramping, often relieved by bowel movements, along with bloating and gas that worsens throughout the day. You may experience diarrhea (IBS-D), constipation (IBS-C), or alternating between both (IBS-M). Other signs include urgency to have bowel movements, feeling like you have not completely emptied your bowels, mucus in your stool, and symptoms that flare up after eating certain foods or during stressful periods.
Who is at risk for IBS?
IBS affects women twice as often as men and typically develops before age 50, with many cases starting in the teenage years or early adulthood. You have higher risk if you have a family history of IBS, experience chronic stress or anxiety, have a history of gastrointestinal infections, or suffer from depression or other mental health conditions. People with food sensitivities, those who experienced childhood trauma, and individuals with other functional disorders like fibromyalgia or chronic fatigue syndrome also face increased risk.
What happens if IBS is left untreated?
Untreated IBS significantly impacts quality of life, leading to chronic discomfort, missed work or school, and social isolation due to unpredictable symptoms. Over time, persistent symptoms can contribute to anxiety and depression, creating a cycle where mental health issues worsen digestive problems. You may develop nutritional deficiencies if you start avoiding multiple foods without proper guidance, and hemorrhoids or anal fissures can develop from chronic diarrhea or straining with constipation. While IBS does not cause permanent damage to the intestines or increase colon cancer risk, ongoing symptoms require management to prevent these complications.
Can IBS be diagnosed with a blood test?
IBS cannot be directly diagnosed with a blood test, as it is a functional disorder diagnosed primarily through symptom assessment and clinical criteria. However, blood tests play a crucial supporting role by ruling out conditions with similar symptoms like celiac disease, inflammatory bowel disease, or thyroid disorders. Food Specific IgG testing helps identify dietary triggers that worsen IBS symptoms, providing actionable information to guide treatment. Your doctor uses blood work alongside your symptom history and physical examination to confirm an IBS diagnosis and develop a personalized management plan.
How is IBS treated?
IBS treatment combines dietary modifications, stress management, and medication tailored to your specific symptoms. Identifying and eliminating trigger foods through IgG testing or elimination diets often provides significant relief, while adding fiber supplements or following a low FODMAP diet helps many people. Medications include antispasmodics for cramping, laxatives for constipation, anti-diarrheal drugs for loose stools, and antidepressants at low doses to reduce pain signals. Probiotics, stress reduction techniques like cognitive behavioral therapy or mindfulness, and regular exercise also improve symptoms by supporting gut health and the gut-brain connection.
How can I prevent IBS?
While you cannot completely prevent IBS, you can reduce your risk and minimize flare-ups by managing stress through regular exercise, adequate sleep, and relaxation techniques like yoga or meditation. Maintain a balanced diet with regular meal times, avoid known trigger foods identified through testing or food diaries, and stay well-hydrated. Limit caffeine, alcohol, and artificial sweeteners that can irritate the digestive system. Building a healthy gut microbiome through probiotic-rich foods and avoiding unnecessary antibiotics also helps maintain digestive balance and reduce symptom severity.
What natural remedies help with IBS?
Peppermint oil capsules provide natural antispasmodic effects that reduce abdominal cramping and bloating in many IBS sufferers. Probiotics containing Bifidobacterium and Lactobacillus strains help restore healthy gut bacteria balance and improve symptoms. Ginger tea soothes digestive discomfort and reduces nausea, while chamomile tea calms intestinal inflammation and anxiety. Fiber supplements like psyllium husk regulate bowel movements for both constipation and diarrhea. Regular physical activity, mindfulness meditation, and keeping a food diary to identify personal triggers are also effective natural approaches to managing IBS symptoms.

What this means

Your testosterone levels are slightly below the optimal range. While this is not necessarily cause for concern, it may contribute to occasional fatigue, reduced motivation, or lower muscle mass over time.

* Regular blood test results (e.g., CBC) typically start arriving the next business day after sample collection. More complex tests, such as hormone panels, may take up to 10–15 business days due to their complexity.
