Why do antibiotics upset my stomach and lower immunity?

I'm really sorry to hear that you're experiencing stomach upset and concerns about your immunity while taking antibiotics. It's completely understandable to be worried about these side effects. Let me provide you with some information that may help clarify what's happening. Antibiotics are designed to fight bacterial infections, but they don't discriminate between harmful and beneficial bacteria. This can lead to a disruption in your gut microbiome, which is the community of microorganisms living in your digestive system. When you take antibiotics, they can reduce the population of these good bacteria, leading to gut disturbances such as an upset stomach, bloating, or diarrhea. Additionally, the gut microbiome plays an essential role in your immune health. A balanced gut flora helps to maintain a robust immune system, so when antibiotics upset this balance, it can potentially lead to weakened immunity. This means your body may not be as efficient at fighting off other infections during and shortly after your antibiotic treatment. If you're experiencing significant discomfort, I recommend discussing this with your healthcare provider. They may suggest probiotics or other strategies to help restore the balance of your gut flora. It's essential to care for your overall health and well-being during this time. Always feel empowered to reach out to a healthcare professional for personalized advice and support.
