We frequently see people rub their belly after a heavy meal. Ever wondered why? It is an instinctive response providing a sense of comfort and helps relieve the feeling of fullness. After eating a large meal, the stomach stretches to accommodate food, which can cause temporary pressure, bloating, or mild discomfort. Gently rubbing the abdomen may provide a soothing sensation by relaxing the abdominal muscles, stimulating intestinal movement and relieving the sensation of tightness or bloating. In simple terms, it means the stomach area is physically swollen, stretched or enlarged outward beyond its normal size

Let us explore the causes of abdominal distension, symptoms, diagnosis and treatment options available at the same time, helping in understanding when to seek medical treatment and make simple lifestyle changes. If the swelling/bloating continues, it is time to seek medical intervention

What is Abdominal distension?

Distention refers to an abnormal increase in the physical size, girth, or volume of the abdomen, mainly due to food consumption followed by fluid or gas buildup. It is normal as long as it deflates as the food gets digested

Common causes of Abdominal Distension

Other causes

• Pregnancy
•  Menstruation, which causes water retention
• Significant recent weight gain, which tends to be stored as intra-abdominal fat and may restrict digestion.
• An obstruction of the small or large bowel, causing a build-up of gas and waste matter
• Partial paralysis of the stomach (gastroparesis) causing a build-up of digestive contents
• Certain gastrointestinal diseases
• Inflammation of the abdominal lining
• A build-up of fluid in the abdomen caused by liver disease
• Inflammation or a growth
• Internal bleeding
• Heart failure leading to fluid retention
• Kidney disease
• Pancreatitis
• Ovarian cysts or ovarian cancer
•  Tumours within the abdomen

Symptoms of Abdominal Distension

Diagnostic strategies

Conducting a thorough clinical history and physical examination of:

• Onset and timing of symptoms
• Relationship to diet
• Use of medications and supplements
• Surgical history
• Bowel movement habits and patterns

Tests include:

• Breath tests
• Endoscopy
• Celiac serologies
• Abdominal imaging (CT or MRI scan)
