Bloating is a common problem in Singapore that affects up to 30% or more of healthy adults.
It is a result of air or gas filling the gastrointestinal (GI) tract, and often presents as fullness, tightness, or pressure in the stomach, possibly accompanied by an obviously swollen or ‘hard’ abdomen, or pain in the abdomen. Bloating can make you feel anywhere between slightly uncomfortable to tremendously painful. The bloatedness can last for a short while or subside only after several hours. Recurrent bloatedness may be the case for those who experience digestive problems and hormonal fluctuations.
Bloating is a common digestive issue where the abdomen feels swollen or tight due to excess gas or fluid buildup in the gastrointestinal tract.
Bloating and excessive gas are common digestive concerns that can cause discomfort, embarrassment, and even disruption to daily activities. While occasional bloating and gas are normal bodily functions, persistent or severe symptoms may indicate an underlying gastrointestinal issue that requires medical attention.
Bloating occurs when the abdomen feels swollen or tight due to excess gas or fluid retention in the digestive tract. This sensation can be accompanied by visible distension, discomfort, and, in some cases, pain. Excessive gas, on the other hand, refers to an increased production or accumulation of gas in the stomach and intestines, leading to frequent belching, flatulence, or cramping.
The digestive system naturally produces gas as a byproduct of breaking down food. However, certain factors, such as diet, gut bacteria imbalances, or digestive disorders can lead to excessive gas production or impaired gas expulsion, resulting in bloating and discomfort. While dietary habits, such as consuming high-fiber foods or carbonated beverages, are common triggers, chronic or severe symptoms may be linked to conditions such as:
Irritable bowel syndrome (IBS) — IBS is a digestive disorder that affects gut motility and sensitivity, leading to bloating, cramping, and irregular bowel movements.
Small intestinal bacterial overgrowth (SIBO) — an overgrowth of bacteria in the small intestine that ferments food too quickly, causing excessive gas and bloating.
Food intolerances — difficulty digesting certain foods, such as lactose or fructose, leading to fermentation in the gut and increased gas production.
Functional dyspepsia — a chronic digestive condition that affects stomach emptying and causes bloating, fullness, and discomfort after eating.
If bloating and excessive gas persist despite lifestyle and dietary changes, a medical evaluation is recommended to identify the root cause and determine an appropriate treatment plan. At Alpine Surgical, we offer comprehensive assessment to help patients find relief from persistent digestive discomfort.
What causes bloating and excessive gas?
Bloating and excessive gas can result from a variety of factors, ranging from dietary habits to underlying medical conditions affecting the digestive system.
Consuming gas-producing foods — One of the most common causes is the consumption of gas-producing foods, such as beans, lentils, cruciferous vegetables, dairy products, and carbonated drinks, which can lead to increased fermentation in the gut.
Eating too quickly — Swallowing air while eating too quickly, chewing gum, or drinking through a straw can also contribute to excessive gas buildup.
Digestive disorders — play a significant role in persistent bloating and gas. Conditions such as:
Irritable bowel syndrome (IBS)can affect gut motility and sensitivity, leading to irregular digestion and excessive gas retention.
Small intestinal bacterial overgrowth (SIBO)occurs when an overgrowth of bacteria in the small intestine ferments undigested food too rapidly, causing bloating, distension, and discomfort.
Functional dyspepsia, a condition affecting how the stomach empties food, and chronic constipation, can trap gas in the intestines.
Coelic disease or inflammatory bowel disease — Bloating may be linked to more serious gastrointestinal conditions, such as coeliac disease, inflammatory bowel disease (IBD), or even blockages in the digestive tract.
Food intolerances — Food intolerances, particularly lactose and fructose malabsorption, can also contribute, as the body struggles to properly break down these sugars, resulting in fermentation and gas production.
Hormonal fluctuations — Hormonal fluctuations, particularly in women, can also influence bloating, with many experiencing increased symptoms before or during menstruation.
Conditions like irritable bowel syndrome (IBS) can disrupt gut movement and sensitivity, which may result in irregular digestion and excessive gas buildup.
What are the symptoms of bloating and gastric issues?
Bloating and excessive gas can present with a range of symptoms, which may vary in severity from mild discomfort to significant abdominal pain. While occasional bloating is common, persistent or severe symptoms may indicate an underlying digestive condition. Recognising these signs can help determine when medical attention is needed. Common symptoms include:
Abdominal swelling or distension — a visibly enlarged or tight abdomen, often worsening after meals.
Fullness and discomfort — a sensation of heaviness or pressure in the stomach, even after eating small amounts.
Excessive belching (burping) — frequent expulsion of gas from the stomach, sometimes with a sour taste.
Flatulence (passing gas) — increased frequency of gas release, often accompanied by discomfort.
Abdominal pain or cramping — sharp, dull, or cramping pain due to trapped gas or digestive irritation.
Gurgling or rumbling sounds — audible noises from the intestines as gas moves through the digestive tract.
Nausea or loss of appetite — feeling queasy or disinterested in food due to prolonged bloating.
Changes in bowel habits — constipation or diarrhoea, often linked to conditions like IBS or food intolerances.
If these symptoms are persistent, severe, or accompanied by weight loss, blood in the stool, or difficulty swallowing, a medical evaluation is essential to rule out more serious gastrointestinal conditions.
Bloating or excessive gas can cause abdominal pain and cramping by stretching the intestines and triggering digestive discomfort.
Who is at risk of bloating and excessive gas issues in Singapore?
While bloating and excessive gas can affect anyone, certain individuals are more prone to experiencing persistent or severe symptoms. Lifestyle, dietary habits, and underlying medical conditions all contribute to the likelihood of developing these digestive issues. In Singapore, individuals at higher risk include:
People with irritable bowel syndrome (IBS) — a functional gut disorder that disrupts normal digestion and gas regulation.
Those with small intestinal bacterial overgrowth (SIBO) — excessive growth of bacteria in the small intestine leads to rapid fermentation of food, resulting in bloating, gas, and discomfort.
People with chronic constipation — slowed bowel movements can trap gas in the intestines, leading to bloating and pain.
Individuals consuming a high-fibre diet — while fibre is essential for digestion, excessive intake without proper hydration can lead to gas buildup.
People experiencing high stress or anxiety — stress impacts gut motility and digestion, which often worsens bloating and gas symptoms.
Women undergoing hormonal changes — fluctuations during menstruation, pregnancy, or menopause can lead to water retention and bloating.
Elderly individuals — ageing affects digestion, enzyme production, and gut motility, which makes bloating more common in this age group.
How are bloating and gastric issues diagnosed?
At Alpine Surgical, we take a comprehensive approach to diagnosing bloating and excessive gas and make sure that we identify the root cause of your symptoms. Since digestive discomfort can stem from various factors, ranging from dietary triggers to underlying medical conditions, we use the following methods to assess your digestive health:
Detailed medical history and symptom assessment — we discuss your symptoms, dietary habits, and medical history to pinpoint potential triggers and patterns.
Physical examination — a thorough abdominal examination helps us detect any tenderness, swelling, or abnormal sounds in the digestive tract.
Blood tests — these help identify underlying conditions such as infections, inflammation, coeliac disease, or metabolic disorders that could contribute to bloating.
Lactose intolerance and food sensitivity tests — we conduct breath or blood tests to check for food intolerances, such as lactose or fructose malabsorption, which often cause excessive gas.
Stool analysis — testing stool samples can reveal infections, digestive enzyme deficiencies, or imbalances in gut bacteria.
Breath tests for small intestinal bacterial overgrowth (SIBO) — a non-invasive test that measures hydrogen and methane levels in the breath after consuming specific sugars, which helps detect bacterial overgrowth in the small intestine.
Endoscopy (gastroscopy or colonoscopy) — for persistent or severe symptoms, we may use a thin, flexible camera to examine the digestive tract for abnormalities such as inflammation, ulcers, or structural issues.
Abdominal imaging (ultrasound, X-ray, or CT scan) — imaging studies help detect blockages, fluid buildup, or structural abnormalities that may be contributing to bloating and gas.
By using these diagnostic techniques, we ensure that you receive an accurate diagnosis and a personalised treatment plan to relieve discomfort and improve your digestive health.
What are the treatment options for bloating and excessive gastric issues in Singapore?
At Alpine Surgical, we take a personalised approach to treating bloating and excessive gas and focus on the underlying cause rather than just managing the symptoms. Since digestive discomfort can stem from dietary habits, gut imbalances, or medical conditions, we tailor treatment plans based on your specific needs. Our goal is to restore digestive health and provide lasting relief. Here are some of the treatment options we offer:
Dietary adjustments and nutrition counselling — our healthcare expert guides you on modifying your diet to reduce gas-producing foods, manage food intolerances, and improve digestion.
Probiotics and gut microbiome support — introducing beneficial bacteria can help balance the gut microbiome, particularly for those with IBS or post-antibiotic digestive issues.
Lactose intolerance and food intolerance management — for patients with food sensitivities, we develop tailored dietary plans and recommend enzyme supplements where necessary.
Treatment for small intestinal bacterial overgrowth (SIBO) — targeted antibiotics or antimicrobial therapy can help restore a healthy bacterial balance in the small intestine.
Management of constipation and motility disorders — if slow digestion or constipation is contributing to bloating, we provide treatment options such as fibre modifications, laxatives, or motility-enhancing medications.
Endoscopic and surgical interventions — for severe cases linked to structural abnormalities, chronic inflammation, or digestive obstructions, we offer comprehensive diagnostic and minimally invasive surgical procedures.
Stress management strategies — recognising the gut-brain connection, we may recommend lifestyle modifications, relaxation techniques, or referrals for stress-related digestive concerns.
