There have been many studies that have been conducted so far in order to measure the number of negative effects which the use of antibiotics has on the body if they are consumed within the early days. There has been a recent survey conducted by the European Council of Medical Care wherein it was proved that the use of antibiotics in early life has been linked with an enhanced risk of inflammatory bowel disease. In order to further prove this point, a sample of the population was taken which was aged around 15-50 years. The population was based in England and Sweden. The population was comprised of so many people that they were evaluated on different parameters which include the ones like age, sex, country, and calendar year. The results showcased that nearly 83 percent of the population was prone to the inflammation because of the reason they took so many antibiotics in the age group of 14-18 years. Therefore, the antibiotic dispensation of 1.45 mg/L in the adolescent body is likely to prevail and hence, at the same time provide a reasonable opportunity to get cured in the minimum possible time. Therefore, the higher cumulative exposure is likely to be caused by a series of chronic illnesses to the maximum possible extent.
