IRRITABLE BOWEL SYNDROME

Irritable bowel syndrome (IBS) is a common gastrointestinal disorder with a range of symptoms that can vary among individuals. Some common symptoms associated with IBS include:

• Abdominal Pain: Crampy or sharp abdominal pain is a hallmark symptom of IBS. The pain is often relieved or improved after having a bowel movement.

• Bloating: Many people with IBS experience abdominal bloating, which can cause discomfort and a feeling of fullness.

• Altered Bowel Habits: IBS can manifest with both diarrhoea-predominant (IBS-D) and constipation-predominant (IBS-C) symptoms. Some individuals may alternate between periods of diarrhoea and constipation.

• Changes in Stool Consistency: Stool consistency may vary, with some individuals experiencing loose or watery stools (diarrhoea), while others may have hard, lumpy stools (constipation).

• Urgency: A sudden and strong urge to have a bowel movement is common in IBS.

• Mucus in Stool: Some individuals with IBS may notice the presence of mucus in their stool.

• Incomplete Evacuation: A feeling that you haven't fully emptied your bowels after a bowel movement is another common symptom.

• Fatigue: IBS can be associated with fatigue and a general feeling of tiredness.

• Anxiety and Depression: Emotional symptoms, such as anxiety and depression, can often accompany IBS, as there is a strong connection between the gut and the brain.

There are three forms of IBS:  

• Irritable bowel syndrome with constipation 

• Irritable bowel syndrome with diarrhoea 

• Mixed irritable bowel syndrome 

The exact cause of irritable bowel syndrome (IBS) remains unclear, and it is believed to be a complex condition with multiple contributing factors. While the exact cause may vary among individuals, several factors have been linked to the development or exacerbation of IBS symptoms. Some of these factors include:

• Gut-Brain Interaction: There is a strong connection between the gut and the brain, and alterations in this gut-brain interaction may play a role in IBS. Stress and psychological factors can trigger or worsen IBS symptoms in some individuals.

• Psychological Factors: Emotional stress, anxiety, and depression can contribute to the development and exacerbation of IBS symptoms. Stress management techniques and psychological therapies may be part of the treatment plan for some individuals with IBS.

• Early Life Events: Some individuals with a history of difficult or traumatic childhood events, such as physical or sexual abuse, may have a higher risk of developing IBS. These early life experiences can have long-lasting effects on the gut-brain axis.

• Infections: In some cases, bacterial infections in the digestive tract (gastroenteritis) have been associated with the onset of IBS symptoms. This is often referred to as post-infectious IBS (PI-IBS).

• Small Intestinal Bacterial Overgrowth (SIBO): An overgrowth of bacteria in the small intestine, known as SIBO, has been linked to IBS symptoms, particularly in individuals with diarrhoea-predominant IBS (IBS-D).

• Food Intolerances: Some individuals with IBS may have specific food intolerances or sensitivities that trigger digestive symptoms. Common culprits include lactose (found in dairy products), fructose, and certain carbohydrates known as FODMAPs.

• Altered Gut Microbiota: Imbalances in the gut microbiota (the collection of microorganisms in the digestive tract) may contribute to IBS symptoms. Research into the role of the gut microbiome in IBS is ongoing.

IBS can present with different predominant symptoms, including diarrhoea-predominant IBS (IBS-D), constipation-predominant IBS (IBS-C), or a combination of both. The choice of treatment depends on the specific symptoms and needs of the individual with IBS.

For IBS with diarrhoea (IBS-D), medical treatments may include:

• Loperamide: Loperamide is an over-the-counter medication that can help reduce diarrhoea and relieve abdominal cramps by slowing down bowel movements.

• Rifaximin: This antibiotic may be prescribed if small intestinal bacterial overgrowth (SIBO) is suspected as a contributing factor to IBS-D symptoms.

• Eluxadoline: Eluxadoline is a prescription medication that can alleviate abdominal pain and diarrhoea associated with IBS-D.

• Alosetron: Alosetron is a prescription medication used in women with severe IBS-D who have not responded to other treatments. It helps slow down bowel movements and reduce pain.

For IBS with constipation (IBS-C), medical treatments may include:

• Fibre Supplements: Fibre supplements, such as psyllium, can help regulate bowel movements and relieve constipation.

• Laxatives: Over-the-counter or prescription laxatives may be recommended to alleviate constipation.

• Lubiprostone: Lubiprostone is a prescription medication that can increase fluid secretion in the intestines, making it easier to pass stools.

• Linaclotide: Linaclotide is a prescription medication that can help relieve constipation and abdominal discomfort by increasing bowel movements.

• Plecanatide: Plecanatide is another prescription medication used to treat IBS-C by promoting regular bowel movements.

For managing abdominal pain associated with IBS, medical treatments may include:

• Antispasmodic Medications: Antispasmodic drugs, such as dicyclomine or hyoscyamine, can be prescribed to relieve abdominal cramping and spasms.

• Antidepressants: Certain antidepressant medications, such as tricyclic antidepressants (TCAs) or selective serotonin reuptake inhibitors (SSRIs), may be used to help manage abdominal pain and discomfort in some cases.

• Coated Peppermint Oil Capsules: Peppermint oil capsules with an enteric coating may provide relief from IBS-related abdominal pain and discomfort.

Natural approaches can be a valuable part of managing IBS symptoms, especially when combined with medical treatments. Here's a bit more detail on natural treatment options:

• Identify Trigger Foods: Many individuals with IBS have specific trigger foods that worsen their symptoms. Keeping a food diary and working with a healthcare provider or dietitian can help identify and eliminate trigger foods from the diet. Some common trigger foods include dairy products, gluten-containing foods, and high-FODMAP foods.

• Low-FODMAP Diet: FODMAPs (fermentable oligosaccharides, disaccharides, monosaccharides, and polyols) are types of carbohydrates that can trigger IBS symptoms in some individuals. A low-FODMAP diet involves avoiding high-FODMAP foods like certain fruits, vegetables, dairy products, and sweeteners. Consulting a dietitian experienced in the low-FODMAP diet is crucial to ensure a balanced and safe approach.

• Probiotics: Some studies suggest that certain probiotics may help alleviate IBS symptoms by promoting a healthy balance of gut bacteria. Probiotics containing Bifidobacterium or Lactobacillus strains are often recommended. However, their effectiveness can vary from person to person.

• Soluble Fibre: Soluble fibre can help regulate bowel movements and reduce diarrhoea in IBS-D (diarrhoea-predominant IBS). Foods rich in soluble fibre include oats, psyllium husk, and certain fruits like bananas and apples.

• Peppermint Oil: Enteric-coated peppermint oil capsules have shown promise in reducing IBS symptoms, particularly abdominal pain and bloating. Peppermint has natural antispasmodic properties that can relax the muscles in the gastrointestinal tract.

• Ginger: Ginger is known for its anti-inflammatory and soothing effects on the digestive system. Ginger tea or capsules may help alleviate nausea and abdominal discomfort.

• Yoga: Practising yoga can help reduce stress and anxiety, which are common triggers for IBS symptoms. Specific yoga poses and breathing exercises may also provide relief from digestive discomfort.

• Mindfulness Meditation: Mindfulness techniques involve staying present and non-judgmentally observing thoughts, sensations, and emotions. Mindfulness meditation can help individuals manage stress and better cope with IBS-related symptoms.

• Acupuncture: Some people with IBS find relief through acupuncture sessions. Acupuncture involves the insertion of fine needles into specific points on the body and is believed to promote balance and reduce pain and discomfort.

• Stay Hydrated: Proper hydration is essential for overall digestive health. Drinking enough water helps maintain the softness of stools and prevents constipation.

• Regular Exercise: Engaging in regular physical activity not only promotes better digestion but also helps reduce stress, which can trigger or worsen IBS symptoms. Activities like walking, jogging, and swimming can be beneficial.

• Manage Stress: Chronic stress can exacerbate IBS symptoms. Stress management techniques such as progressive muscle relaxation, deep breathing exercises, and biofeedback can be helpful.
