Dyspepsia

Overview of the Dyspepsia Market

With the growing prevalence of gastrointestinal diseases, the growth of the worldwide dyspepsia market is accelerating. Owing to a stable CAGR of 3.3% through the forecast period, the valuation of the ecosystem is expected to increase from USD 5.53 billion in 2023 to USD 7.91 billion by 2035.

Dyspepsia is a common and perplexing condition that affects approximately 30% of the population. It primarily affects the upper abdomen and differs from other digestive diseases such as gastroesophageal reflux disease (GERD) and irritable bowel syndrome (IBS).

It can be associated with various types of organic, systemic, and metabolic disorders; however, in nearly 50% of patients, no clear underlying cause can be identified, making the condition difficult to diagnose. Diagnosis generally aims to evaluate whether the patient has an organic disorder, such as gastric cancer or GERD.

Dyspepsia does not typically involve any structural, psychological, or microbiological abnormalities. The wide range of dyspeptic symptoms suggests different underlying pathogenic mechanisms.

Most international committees have proposed dividing patients into distinct dyspepsia subgroups based on symptom clusters, with the goal of better understanding and managing the condition.

Symptoms and GERD

When a patient complains not only of heartburn but also of discomfort during routine activities, a diagnosis of GERD can often be made. It is particularly recommended in chronic cases where it is necessary to rule out the presence of Barrett’s metaplasia.

According to recent studies, acid exposure monitored through 24-hour pH testing shows the highest scores in such patients. Retrospective analyses indicate that severe heartburn enough to interfere with daily activities slightly increases the risk of developing adenocarcinoma of the gastric cardia.

Subgroups of Dyspepsia

According to recent studies, a university-based clinical assessment of 483 patients with chronic functional dyspepsia examined the relationship between symptom patterns, demographic features, and gastric dysmotility. Patients reported symptoms such as postprandial fullness, nausea, vomiting, and epigastric burning sensations.

Response to Treatment

Predominant symptoms may be useful in predicting how patients respond to treatment. For example, patients experiencing predominant epigastric pain often show significant long-term improvement with appropriate therapy.

Those with symptoms suggesting GERD typically have non-functional dyspepsia and tend to experience relief with proton pump inhibitor (PPI) therapy, which remains one of the most effective treatment options.

Improving Diagnosis

Accurate diagnosis of dyspepsia largely depends on the patient’s description of subjective symptoms. Quantitative assessments are often difficult, and well-validated tools are needed to better define and track the disorder’s progression.

The reliability of diagnostic questionnaires depends on clear descriptive language and standardized comparison tools. In evaluating patients with suspected GERD, studies have shown varying recognition rates of heartburn between different questionnaires.

To effectively manage dyspepsia, individual symptoms must be verified, and specific measures must be established. Identifying predominant symptoms remains essential for classifying subgroups and ensuring targeted treatment.

Regional Analysis

In North America and Europe, functional dyspepsia is more frequently linked to stress, dietary triggers, and sedentary lifestyles. Widespread awareness and access to PPIs support early diagnosis and management.

In the case of the Asia-Pacific region, higher incidence rates are observed due to Helicobacter pylori infection, spicy diets, and irregular eating patterns. Regional healthcare initiatives are increasingly focused on preventive screening and awareness campaigns.
