These drugs often cause gastrointestinal side effects, such as:
These side effects may be uncomfortable, but they tend to pass quickly.
Eating the right foods can help to prevent bothersome side effects and encourage healing. In this article, learn which foods to eat and which to avoid while taking antibiotics.
What to eat during and after taking antibiotics
Certain foods or drinks may affect antibiotics.
A person has trillions of bacteria and other microorganisms living in their gut. The medical community refers to these organisms, collectively, as the gut microbiome.
Antibiotics fight bacteria, and they can upset the balance of bacteria in the microbiome.
The gut microbiome keeps the digestive system functioning and helps the immune system to defend against viral infection.
When antibiotics upset the bacterial balance, a person may experience side effects, such as nausea or diarrhea. Consuming probiotics and prebiotics during and after a course of antibiotics can help to restore the balance of bacteria in the gut.
Probiotics are live microorganisms commonly known as “healthy bacteria.”
They can help to reduce some of the side effects of antibiotics, such as bloating and diarrhea.
While research about probiotics and antibiotics is still inconclusive, studies suggest that taking probiotics is a safe way to prevent antibiotic-related diarrhea.
Antibiotics can kill the beneficial bacteria in probiotics, so it is advisable to take the two a few hours apart.
After finishing a course of antibiotics, taking a mixture of probiotics can also help to restore balance in the microbiome.
Prebiotics are food for the beneficial bacteria that live in the gut microbiome.
Feeding the beneficial bacteria before and after taking antibiotics can help to bring balance back to the gut.
Some foods contain low levels of prebiotics, such as:
Manufacturers sometimes add prebiotics to foods, such as:
- infant formula
Prebiotics may appear on food labels as:
- galactooligosaccharides, or GOS
- fructooligosaccharides, or FOS
- oligofructose, or OF
- chicory fiber
Most prebiotics are dietary fibers. If a person consumes large quantities, they may experience gas or bloating.
Anyone who is considering adding prebiotics to their diet should do so slowly to allow their gut to adapt.
