Antibiotics may be effective at eliminating bacterial infections in the body, but they also disrupt the balance of desirable and undesirable bacteria in the gut. This can leave the digestive tract available for pathogenic bacteria to take up residence making it harder for the friendly bacteria to re-colonise to beneficial levels.
The symptoms of an imbalance of gut flora are: bloating, constipation, diarrhoea, indigestion, IBS and food intolerances. Friendly bacteria are found in cultured foods such as live yoghurt, cottage cheese, miso, sauerkraut, tofu, tamari, and kefir.
However, these may not be enough, and a friendly bacteria supplement known as a probiotic may be beneficial. You can research lots of information on probiotic supplements on the internet or you may choose to discuss with a dietician or nutritionist.
