This last cause of bloating is not as common but it is still be a problem. High doses or long courses of antibiotics can cause a disruption in the amount and balance of the bacteria in your digestive track. Basically this bacteria is collateral damage in the antibiotics battle against the pathogenic bacteria that was making you sick. The result is that the landscape of good bacteria in your intestines is greatly diminished leading to impaired digestion and bloating. Fortunately the fix here is simple – probiotics. A 30 day course of probiotics will help repopulate your intestines with the bacteria it needs to maintain a healthy digestive process eliminating the cause of any bloating.
