Antibiotics are important medicines that can treat serious infections. They can also affect the helpful bacteria in your gut, and some people get an upset stomach or diarrhea. This article covers simple food and habit steps to support your gut during and after antibiotics, and the warning signs that need a doctor right away. ## Always Finish Your Antibiotics as Prescribed Before anything else, this needs to be clear. Do not skip doses, stop early, or change how you take your antibiotic because of gut concerns. The CDC’s guidance on [antibiotic use](https://www.cdc.gov/antibiotic-use/about/index.html) says to take antibiotics exactly as prescribed. It also says: - Do not share your antibiotics with others. - Do not save them for later. - Do not take antibiotics prescribed for someone else. If you have side effects, call the doctor who prescribed the antibiotic. They may have advice or may change your medicine. That decision belongs to your doctor. The tips in this article are meant to go alongside your antibiotic, never in place of it. ## Why Antibiotics Affect Your Gut Antibiotics work by killing bacteria or stopping them from growing. They are great at fighting the bacteria that cause infections. But they cannot always tell the difference between harmful bacteria and the helpful bacteria that live in your gut. Your gut is home to a large community of microbes that help with digestion and support your immune system. When an antibiotic reduces some of these helpful bacteria, the balance can shift for a while. Many people notice changes like loose stools, gas, or bloating. The CDC lists diarrhea as one of the common side effects of antibiotics. The CDC also reminds us that antibiotics do not work on viruses, such as colds and flu. Using them only when they are truly needed is one of the best ways to protect your gut. ## Know About C. diff The most serious gut problem linked to antibiotics is an infection called _ (short for _ ). The CDC explains in its overview of [C. diff infection](https://www.cdc.gov/c-diff/about/index.html) that it is a germ that causes diarrhea and inflammation of the colon, and that it can be life-threatening. According to the CDC, you are up to 10 times more likely to get _ while taking an antibiotic and during the month after you finish. Most cases happen during or soon after antibiotic use. People who are 65 or older, have a weakened immune system, or have had _ before are at higher risk. The CDC lists these symptoms of _ : - Diarrhea - Fever - Stomach tenderness or pain - Loss of appetite - Nausea ## When to Call a Doctor Right Away Call your doctor right away if you are taking an antibiotic, or finished one recently, and you have: - Diarrhea that is severe, frequent, or watery - Blood in your stool - Fever - Strong belly pain or cramping - Signs of dehydration, such as dizziness, very dark urine, or peeing very little Do not try to manage these at home. The CDC advises contacting a healthcare professional if you get diarrhea while taking an antibiotic or after taking one. ## Gut Health After Antibiotics: Food Tips For mild, normal side effects, gentle food choices can help you feel better while your gut adjusts. Always check with your doctor or pharmacist about whether to take your antibiotic with food, and whether to avoid any foods or drinks with your specific medicine. ### During your antibiotic - Stay hydrated. Sip water through the day, especially if your stools are loose. - Eat simple, easy meals. Soups, rice, bananas, oatmeal, eggs, and cooked vegetables are gentle on the stomach. - Go easy on greasy and very spicy foods if your stomach is upset. - Limit alcohol. Ask your pharmacist if it is safe with your antibiotic. ### After your antibiotic Once you finish, you can help your gut recover by feeding the helpful bacteria: - Add fiber back slowly. Beans, lentils, oats, fruits, and vegetables feed helpful gut microbes. Add them a little at a time. - Include fermented foods. Yogurt or kefir with live and active cultures, and refrigerated sauerkraut or kimchi, contain live microbes. - Eat a variety of plants. Different microbes thrive on different foods. - Cut back on added sugar and highly processed foods. These tend to be low in the fiber your gut needs. ## What About Probiotics? Many people ask about probiotics with antibiotics. The research is promising in some areas but still mixed. The National Center for Complementary and Integrative Health (NCCIH) explains in its overview of [probiotics: usefulness and safety](https://www.nccih.nih.gov/health/probiotics-usefulness-and-safety) that different types of probiotics may have different effects. A result for one strain does not apply to others. The NCCIH says some studies suggest probiotics may lower the chance of antibiotic-related diarrhea, but it calls that evidence tentative. It also says the best types, doses, and lengths of use are still not known. And it notes that the risk of harmful effects is greater in people who are very ill or have weakened immune systems. Because of this, talk with your doctor or pharmacist before you take a probiotic with an antibiotic. This is especially important if you have a weakened immune system or a serious illness. They can also tell you how to space a probiotic apart from your antibiotic if they think it is a good idea for you. ## A Simple Antibiotic Gut Care Checklist - Take every dose exactly as prescribed, until it is done - Ask your pharmacist about food, drinks, and timing - Drink water through the day - Eat simple meals if your stomach is upset - Watch for severe, watery, or bloody diarrhea or fever, and call your doctor right away if they happen - After you finish, add fiber and fermented foods back slowly - Ask your doctor before starting a probiotic ## How We Can Help At Living Well, we help people build eating habits that support their digestion over the long term.
