Final answer:
Dyspepsia, or indigestion, refers to symptoms of impaired digestion, such as abdominal discomfort and heartburn, often without an underlying organic disease. It can be related to stress, dietary habits, medications, and sometimes organic diseases like GERD, gastritis, or peptic ulcers. Dyspepsia is also associated with serotonin levels, which affect gut function and a general sense of well-being.
Step-by-step explanation:
Dyspepsia, commonly known as indigestion, is a medical condition characterized by impaired digestion. People with dyspepsia may experience symptoms such as upper abdominal fullness or pain, heartburn, nausea, belching, or a combination of these. It most often occurs without evidence of an underlying organic disease. However, it can also be symptomatic of conditions like gastroesophageal reflux disease (GERD), gastritis, peptic ulcers, or in rare cases, cancer. A peptic ulcer is a sore in the stomach or duodenal lining often associated with Helicobacter pylori infection, leading to symptoms like abdominal pain, which may improve after eating, belching, and vomiting. Stress can exacerbate functional dyspepsia and conditions like irritable bowel syndrome, which involve the neurotransmitter serotonin, linked to a sense of well-being and gut function.
