If you’re on antibiotics, your digestive health is likely to feel a bit off. Here’s what you can do to maintain the balance and restore gut functions to normalcy.
Antibiotics are one of the most frequently prescribed drugs and act only on bacterial infections, not viruses. It is important to only use them under a physician's advice because misuse can make bacteria resistant.
While it is necessary to treat infections, antibiotics can interfere with the balance of good bacteria in the gut. Dr Pooja Pillai, Consultant – Internal Medicine, Aster CMI Hospital, Bengaluru, explains how antibiotics impact gut health and shares advice on how to restore balance afterwards.
How Antibiotics Help Gut Flora and Digestion
Antibiotics are used to fight off harmful bacteria, but they also disturb the good bacteria in your gut.“These ‘good’ microbes play a big role in digestion, nutrient absorption, and even immune function,” says Dr Pillai, adding, “When antibiotics wipe out both bad and beneficial bacteria, you might notice digestive issues like bloating, Diarrhoea, or an upset stomach.”Citing an example, she explains, “It’s like throwing off the balance in a tiny ecosystem. Some people bounce back quickly, while others need more time to restore their gut health. Taking probiotics or eating fermented foods can help support recovery during or after a round of antibiotics.”
Foods To Eat to Restore Gut Health After Antibiotic Use
After antibiotics, your gut could use a little extra care.According to Dr Pillai, foods rich in probiotics and prebiotics can help restore the good bacteria. “Think yoghurt with live cultures, kefir, sauerkraut, kimchi, miso, and other fermented goodies, as they’re full of friendly microbes,” she recommends, adding that prebiotic foods like bananas, garlic, onions, oats, and asparagus can help feed those good bacteria.“It’s also helpful to eat a variety of fiber-rich fruits, veggies, and whole grains to keep things moving and balanced. Staying hydrated and limiting sugar and processed foods can support recovery too,” the doctor adds.
Can Probiotics Help?
The International Scientific Association for Probiotics and Prebiotics defines probiotics as live microorganisms that provide health benefits to the host when consumed in sufficient amounts.Dr Pillai says, “Probiotics can be taken both during and after a course of antibiotics, but timing matters. If you take them while on antibiotics, try to space them out by taking probiotics a few hours after your antibiotic dose to help more of the good bacteria survive. This can help reduce side effects like Diarrhoea.”
She adds, “Continuing probiotics for a couple of weeks after finishing antibiotics gives your gut extra support to rebuild its healthy bacteria. Everyone’s body reacts differently, but many find that this approach helps balance things out faster. When in doubt, a quick chat with your doctor can guide you.”
How Long Does It Take for A Digestive System to Recover from Antibiotic Use?
The duration of time it takes for the gut microbiome to restore after taking antibiotics varies, but it's usually a few weeks to a few months.At first, the gut might feel somewhat off due to bloating, unpredictable bowel movements, or discomfort. While some individuals recover quickly, others may take longer to rebuild their healthy gut bacteriaEating a balanced diet with prebiotics, probiotics, and fiber-rich foods can help speed up the process. Everyone’s gut is different, so if symptoms persist or you’re concerned, it’s always a good idea to check in with your doctor for personalized advice.
