Final answer:
False, Peptic ulcers are not mainly due to diet but are often caused by H. pylori or NSAIDs. Anti-inflammatory medications can help with diseases like IBD but also cause peptic ulcers with chronic use. Frequent screening for colorectal cancer is advised for those with ulcerative colitis.
Step-by-step explanation:
The question is concerned with gastrointestinal (GI) issues, particularly related to certain medications and conditions. For question 11, it's a common misconception that peptic ulcers are mainly caused by diet; however, they are primarily caused by the bacteria Helicobacter pylori, or long-term use of nonsteroidal anti-inflammatory drugs (NSAIDs). Therefore, the statement is false.
For question 12, an example of a disorder of the GI tract that can be helped by anti-inflammatory medications is inflammatory bowel disease (IBD), like Crohn's disease or ulcerative colitis. On the other hand, chronic use of NSAIDs can lead to the development of peptic ulcers or worsen existing ulcerative colitis, highlighting the complex nature of medication side effects.
For question 13, people with ulcerative colitis need to be frequently screened for colorectal cancer due to the increased risk associated with long-term inflammation of the colon.
