Functional dyspepsia is a chronic digestive condition that causes recurring upper abdominal discomfort without any visible structural abnormality found during investigations such as endoscopy or imaging.
Many patients describe it as having a “sensitive stomach”, where symptoms continue despite repeated tests appearing normal.
The condition is believed to result from disturbances in stomach function rather than structural disease.
This includes:
In busy urban environments, irregular meal timing, sleep disruption, stress and long-term dietary habits may worsen symptoms over time.
For some patients, symptoms fluctuate significantly. There may be periods of improvement followed by flare-ups triggered by stress, travel, oily meals, caffeine or poor sleep.
In many patients from the Philippines, these symptoms are initially attributed to “hyperacidity”, stress, irregular meals or gastric irritation. Some individuals self-medicate repeatedly with antacids or acid suppression medications before seeking further specialist evaluation.
The common symptoms may include:
Unlike ulcers or gastritis, functional dyspepsia does not involve visible damage to the stomach lining. Instead, the problem relates more to how the stomach functions and processes sensations.
Functional dyspepsia can affect adults of all ages, but certain lifestyle, dietary and medical factors may increase the likelihood of developing persistent symptoms.
These risk factors may include:
Colitis can affect people of different ages, although certain medical, lifestyle and environmental factors may increase the likelihood of developing bowel inflammation.
One of the challenges with functional dyspepsia is that its symptoms often overlap with other digestive conditions, such as:
In some cases, persistent symptoms may also create concern about more serious conditions such as stomach cancer. Because of this overlap, proper medical evaluation is important before confirming a diagnosis of functional dyspepsia.
The assessment may involve:
Many people experience occasional indigestion. However, further evaluation becomes important when symptoms:
Medical assessment is especially important if symptoms are associated with:
These features may require more urgent investigation.
The treatment is tailored according to the symptom pattern, severity and contributing triggers. In many cases, improving symptoms requires a combination of digestive management, lifestyle adjustment and long-term symptom control strategies.
Many patients improve gradually when treatment addresses both digestive symptoms and contributing lifestyle factors. Because symptoms vary significantly between individuals, treatment is often adjusted progressively based on response over time.
In the Philippines, persistent indigestion is often broadly labelled as “hyperacidity” or gastritis. However, many patients continue experiencing symptoms despite repeated acid medications because the underlying condition may actually be functional dyspepsia rather than inflammation of the stomach lining.
The overlap in symptoms can make both conditions difficult to distinguish without proper evaluation.
FEATURE | FUNCTIONAL DYSPEPSIA | GASTRITIS |
Underlying issue | Abnormal stomach function and sensitivity | Inflammation of the stomach lining |
Endoscopy findings | Usually normal | May show redness, inflammation or erosions |
Common symptoms | Bloating, fullness, upper abdominal discomfort | Burning pain, nausea and indigestion |
Relationship to stress | Symptoms commonly worsen with stress and poor sleep | Stress may aggravate symptoms, but inflammation is present |
Treatment focus | Gut–brain regulation and stomach function | Treating inflammation and underlying causes |
Long-term pattern | Often fluctuates with flare-ups | Depends on the cause and severity of inflammation |
The good news is that functional dyspepsia is not considered life-threatening, but persistent symptoms can significantly affect daily quality of life.
That is why many patients experience:
For some individuals, the uncertainty itself becomes emotionally exhausting, especially after multiple consultations or inconclusive investigations. However, understanding that functional dyspepsia is a recognised medical condition, rather than “just stress” or “just acidity,” often helps patients approach treatment more constructively.
If you are travelling from the Philippines for treatment, arrangements can be made with Alpine Surgical Practice before your trip to help ensure a smooth and efficient experience.
An online consultation with Dr Aaron Poh can be arranged before you arrive in Singapore.

Patients are encouraged to contact the clinic ahead of time so that appointments and investigations can be arranged around their travel dates whenever possible, ensuring a more seamless experience during their visit to Singapore.
At Alpine Surgical Practice, evaluation begins with understanding the full pattern of your symptoms, including meal-related triggers, previous treatments, stress factors and prior investigations. This helps determine whether symptoms are more consistent with functional dyspepsia or whether additional assessment may still be required.
Dr Aaron Poh carefully reviews each patient’s digestive history to ensure treatment recommendations are clinically appropriate, targeted and practical for long-term symptom control.
If you have persistent upper abdominal discomfort, bloating or recurring indigestion symptoms despite previous treatment, early specialist assessment can help provide greater clarity and a more structured management approach.
