About Antibiotics

The word Antibiotic literally means "against" (anti) "life" (biotic).

Many Antibiotics are actually Naturally produced by Microorganisms (Bacteria or Fungi) to kill or slow the growth of other Microorganisms. They are purified by pharmaceutical companies for use in treatment.

Other antibiotics can be fully produced in the laboratory and are called Synthetic Antibiotics.

Semisynthetic antibiotics are chemically modified Natural antibiotics. These chemical modifiers can enhance many different properties of the Antibiotic, including:
- Protection from Bacterial Resistance
- Alter Tissue Distribution and/or Absorption
- Reduce Toxicity / Side Effects

Antibiotics and Inflammatory Bowel Diseases

Patients with Inflammatory Bowel Disease (IBD) often have alteration in Gastrointestinal Microbe balance or Bacterial Overgrowth. The greatest numbers of bacteria are found in areas of the Terminal Ileum and the Colon.

Antibiotics can be given to IBD patients:
-- To Treat an Existing Infection
-- To Prevent Against the Patient Getting an Infection (also called Antibiotic Prophylaxis or Prophylactic Antibiotic Treatment)
-- During Surgery or Certain Tests / Treatment to reduce Infection and Bacteremia Risk
---- Colonoscopy (0 - 25% Risk) [3]
---- Esophageal Bougienage (12 - 22% Risk) [3]
---- Flexible Sigmoidoscopy (0 - 1% Risk)[3]
---- Gastroscopy (0 - 8% Risk)[3]
---- Stricture Dilation [3]
---- Variceal Ligation (1 - 25%)or Sclerotherapy (0 - 52%)[3]
