#HEALTH: What lies beneath

The human gastrointestinal system is more than just a tool for breaking down and processing food. It plays a crucial role in maintaining the body's overall health and well-being, with a complex network of microorganisms known as the gut microbiome. This microbiome communicates with the brain through what is called the gut-brain axis, meaning that emotional and stress-related changes can impact gut function, while gut signals can also influence bodily sensations and symptoms.

Identifying an unhealthy gut is not straightforward, as there is no single symptom that definitively indicates a healthy or unhealthy gut. Rather, it's the pattern, frequency, persistence, and severity of symptoms that matter. Common digestive signs include bloating, abdominal discomfort, constipation, diarrhoea, excessive gas, changes in bowel habits, and recurrent heartburn.

While occasional digestive symptoms are common and may not signal a serious issue, persistent or worsening symptoms should not be dismissed as normal.

Diet plays a significant role in gut health, though it's not the sole determinant. A diet lacking in fibre and vegetables, particularly prevalent in Malaysia according to the National Health and Morbidity Survey 2023, can negatively impact digestive health. Factors like physical inactivity, poor hydration, inadequate sleep, and stress can also affect the gut. In individuals with conditions like irritable bowel syndrome (IBS), stress can exacerbate symptoms, as it is a disorder of gut-brain interaction.

Bloating is a common symptom, not a diagnosis, and can stem from numerous causes, including dietary factors, constipation, food intolerances, functional gastrointestinal disorders, and other digestive conditions. However, experiencing bloating alone does not automatically mean someone has IBS. Dietary restrictions vary from person to person, as some individuals may have specific food triggers while others may not.

For those with a diagnosed gastrointestinal condition, dietary advice should be tailored to the individual, rather than based on general restrictions.

Probiotic supplements are another area of concern. While some parents give their children probiotics believing them to be beneficial, Dr Suresh advises against assuming that every child requires these supplements. Evidence supporting probiotics varies depending on the specific strain, dose, age of the child, and the condition being treated.

For healthy children with normal growth and a varied diet, a balanced diet is the priority rather than automatically adding supplements. Health organizations also advise that generally healthy children do not need unnecessary supplementation when they are consuming a varied diet. Ultimately, achieving optimal gut health does not require expensive products; it starts with a varied and balanced diet, adequate fibre and fluids, regular physical activity, sufficient sleep, and effective stress management.
