If you take antibiotics repeatedly, you diminish the population of good bacteria that protects you against the "harmful" bacteria. In addition, the "harmful" bacteria become more resistant (harder to kill with antibiotics the next time). Over 100 different helpful intestinal bacteria are lost with the use of antibiotics which then give pathogenic (disease-causing) microbes the chance to proliferate and fill the ecologic vacuum created by the repeated administration of antibiotics.
