If we take a holistic approach, treatment in bacterial overgrowth syndrome (BOS) should include correction of the primary underlying disease, if any, including antibiotic therapy and nutritional support.
In your case, IBS (irritable bowel syndrome) and malabsorption syndrome secondary to celiac disease could be the reason for this.
Studies show that Rifaximin eradicates bowel overgrowth syndrome in as many as 80 % of patients.
Higher doses (1200 or 1600 milligrams per day) are more effective than standard doses (600 or 800 milligrams per day).
Long-term favorable clinical results have been achieved with Rifaximin in patients with irritable bowel and bacterial overgrowth syndrome.
Flagyl (Metronidazole) is often tried, with results around 60 %. As it is readily available, so it is still worth trying.
Other antibiotics have also been used, like Tetracycline, Ciprofloxacin, and Co-amoxiclav.
Nutritional support with dietary modifications such as a lactose-free diet, vitamin replacement, and correction of deficiencies in nutrients like calcium and magnesium should be an important part of bacterial overgrowth syndrome treatment if present.
Methane formation occurs as bacterias ferment the products, so bacteria cause fermentation. Words are quite interchangeable.
