Functional dyspepsia (FD) is a prevalent gastrointestinal disorder causing persistent indigestion. It affects millions of people worldwide, including a significant number in India. Understanding FD is crucial for better managing indigestion and improving quality of life. Our aim with this blog is to educate readers about the causes, symptoms, and management of functional dyspepsia.

What is Functional Dyspepsia?

Functional dyspepsia is a long-term condition characterized by discomfort or pain in the upper abdomen without a clear physical cause. This common but often misunderstood condition affects the upper digestive tract, leading to chronic or recurring pain and discomfort between the navel and the lower end of the ribcage. The term “functional” indicates that there are no visible signs of disease or structural abnormalities in the digestive tract upon examination, despite the presence of symptoms.

In India, functional dyspepsia is prevalent, with studies showing a 30.4% prevalence rate in Mumbai. It indicates that nearly one-third of people may suffer from symptoms of dyspepsia without an identifiable cause.

Distinction Between Functional and Organic Dyspepsia.

Understanding the difference between functional and organic dyspepsia is essential:

• Organic Dyspepsia: This type is caused by identifiable physical conditions such as peptic ulcers, gastroesophageal reflux disease (GERD), or gastric cancer. These conditions can be detected through diagnostic tests like endoscopy or imaging studies.
• Functional Dyspepsia: In contrast, FD does not have a visible cause that can be identified through standard medical tests. The digestive system appears normal, but the patient still experiences significant discomfort.

Causes of Functional Dyspepsia

Understanding the causes of functional dyspepsia is essential for effective management. Several factors contribute to the development of FD, including:

• Helicobacter pylori (H. pylori) Infection: This bacterium is linked to many gastrointestinal issues. Studies show that among H. pylori-positive FD patients, 56% were male, 58.89% were below 40 years, and 53.33% belonged to the middle-income group.
• Gastrointestinal Motility Issues: Problems with the movement of food through the digestive tract can lead to symptoms of FD.
• Psychological Factors: Stress and anxiety can exacerbate or even cause symptoms of FD. The brain-gut connection plays a crucial role in how stress impacts digestion.

Symptoms and Diagnosis

Functional dyspepsia (FD) manifests through a variety of symptoms, which can vary in intensity and frequency. Understanding these symptoms and the methods used for diagnosing FD is essential for effective management.

Common Symptoms

Functional dyspepsia typically presents with the following symptoms:

• Epigastric Pain: A burning or aching pain located in the upper abdomen. This pain is often persistent and can be severe enough to impact daily activities.
• Bloating: A feeling of fullness or swelling in the abdomen, which can be uncomfortable and distressing.
• Belching: Frequent belching or burping can occur, often providing temporary relief from discomfort.
• Nausea: Some individuals may experience nausea, sometimes accompanied by a feeling of wanting to vomit.

These symptoms can significantly affect the quality of life, making routine activities challenging.

Importance of Accurate Diagnosis

Accurate diagnosis of FD is crucial as it helps differentiate it from other gastrointestinal disorders that might require different treatment approaches. Due to the overlapping nature of gastrointestinal symptoms, a thorough diagnostic process is essential.

Diagnostic Methods

The following diagnostic methods are commonly used to identify FD:

• Endoscopy: This procedure involves inserting a flexible tube with a camera into the digestive tract to visually inspect the stomach and upper intestines. Endoscopy helps rule out other conditions such as ulcers, tumors, or gastritis. While FD does not show structural abnormalities, mild gastritis is often a common finding during endoscopy in FD patients.
• H. pylori Testing: Helicobacter pylori infection is a known contributor to FD. Testing for H. pylori can be done through breath tests, stool tests, blood tests, or biopsies taken during endoscopy. If H. pylori is present, eradicating the infection can significantly alleviate symptoms.
• Symptom Assessment: A detailed evaluation of symptoms is critical. Physicians often use standardized questionnaires and scales to assess the frequency, severity, and impact of symptoms on the patient’s life. This assessment helps in tailoring the treatment plan to the individual’s specific needs.

Mild Gastritis as a Common Endoscopic Finding

In many cases, patients with FD might show signs of mild gastritis upon endoscopy. While this inflammation of the stomach lining does not cause FD, it can coexist with it, adding to the patient’s discomfort. Addressing mild gastritis can be part of a comprehensive treatment plan for those with FD.

In summary, recognizing the symptoms of functional dyspepsia and pursuing accurate diagnostic methods are fundamental steps in managing the condition effectively. If you experience persistent symptoms of indigestion, seeking medical advice is essential for appropriate diagnosis and treatment.

Impact on Quality of Life

FD significantly affects daily life and overall well-being. Patients often experience discomfort that hampers their routine activities. There is a pressing need for validated, disease-specific questionnaires in Hindi to assess the health-related quality of life (HRQOL) of Indian patients with FD. Despite its prevalence, comprehensive Indian data on FD’s impact on HRQOL is lacking.

Management and Treatment Options

Managing functional dyspepsia (FD) involves a multi-faceted approach that includes lifestyle changes, medical treatments, and sometimes alternative therapies. Each person’s experience with FD can differ, so it is important to tailor management strategies to individual needs. Below, we delve into various approaches to managing and treating FD effectively.

Lifestyle Modifications

1. Dietary Changes:
   • Avoid Trigger Foods: Certain foods can exacerbate FD symptoms. Spicy, fatty, and fried foods are common culprits. Reducing the intake of these foods can help manage symptoms.
   • Smaller, Frequent Meals: Eating smaller meals more frequently instead of three large meals can ease the digestive process and reduce symptoms.
   • Healthy Eating Habits: Incorporate more fiber-rich foods like fruits, vegetables, and whole grains, which can aid digestion.
2. Stress Management:
   • • Mindfulness and Relaxation Techniques: Practices like yoga, meditation, and deep breathing exercises can help reduce stress and anxiety, which are known to aggravate FD symptoms.
     • Cognitive Behavioural Therapy (CBT): For those whose FD is significantly influenced by psychological factors, CBT can be an effective way to manage stress and improve symptoms.
3. Regular Physical Activity:
   • • Exercise: Regular physical activity can improve gastrointestinal motility, helping to move food through the digestive system more efficiently. Aim for at least 30 minutes of moderate exercise, such as walking or cycling, most days of the week.

Medical Treatments

1. Proton Pump Inhibitors (PPIs):
   • Acid Reduction: PPIs reduce stomach acid production, which can help alleviate symptoms like heartburn and indigestion. Common PPIs include omeprazole and lansoprazole.
2. H. pylori Eradication Therapy:
   • Antibiotics: If H. pylori infection is detected, a course of antibiotics combined with PPIs can eradicate the bacteria and significantly reduce symptoms.
3. Prokinetics:
   • Improved Motility: Prokinetic agents, such as metoclopramide, help enhance the movement of food through the digestive tract, reducing bloating and discomfort.
4. Antidepressants:
   • Low-dose Antidepressants: Tricyclic antidepressants (TCAs) and selective serotonin reuptake inhibitors (SSRIs) in low doses can help manage symptoms related to stress and anxiety, which are often associated with FD.
