Probiotics are defined as ‘live micro-organisms which, when administered in adequate amounts, confer a health benefit on the host. Therefore our bodies naturally need such organisms. Our digestive system is home to more than 500 different types of bacteria. They help keep the intestines healthy and assist in digesting food. They are also believed to help the immune system.
Our digestive system normally has what we would call “good” bacteria and “bad” bacteria. Maintaining the correct balance between the “good” bacteria and the “bad” bacteria is necessary for optimal health. Things like medications, diet, diseases, and your environment can upset that balance.
It is believed that some digestive disorders happen when the balance of friendly bacteria in the intestines becomes disturbed. This can happen after an infection or after taking antibiotics. Intestinal problems can also arise when the lining of the intestines is damaged. Taking probiotics may help.
