Based on the information provided, I was unable to find a specific percentage of patients that experience gastrointestinal (GI) problems while on Tigecycline. However, I was able to find some information regarding the side effects of this drug.

Tigecycline is an antibiotic used to treat various infections caused by bacteria. Like many other antibiotics, Tigecycline can cause side effects, and GI problems are among them. According to the Tigecycline label from the U.S. Food and Drug Administration (FDA) [1]:

* Nausea occurred in 29% of patients in clinical trials
* Vomiting occurred in 17% of patients in clinical trials

These GI side effects can impact a patient's willingness or ability to continue taking the medication. It is essential to consult with healthcare professionals to weigh the benefits and risks of Tigecycline or any other antibiotic treatment.
