1. Gastrointestinal agent

The gastrointestinal tract (GIT) is a complex system responsible for digestion and waste elimination, including organs like the esophagus, stomach, intestines, rectum, and anus. When GIT functions are impaired, conditions such as achlorhydria, hyperacidity, diarrhea, constipation, and swallowing difficulties can arise. To address these issues, various agents are used: acidifying agents to increase stomach acidity, antacids to neutralize excess gastric acid, and laxatives to relieve constipation.

Quadrant - IV (MCQs)

Which of the following conditions is caused by the absence or insufficient secretion of hydrochloric acid in the stomach?

A: Hyperacidity B: Achlorhydria C: Diarrhea D: Constipation

What happens when toxins or insufficient fluid absorption occurs in the intestine?

A: Constipation B: Hyperacidity C: Diarrhea D: Achlorhydria

What is the role of hydrochloric acid in the stomach?

A: Neutralizes stomach acid B: Softens fibrous food and kills bacteria C: Increases blood pH D: decreses blood pH

What is the result of long-term use of calcium carbonate as an antacid?
