A “sensitive stomach” in medical terms means non-ulcer or functional dyspepsia. In this case, indigestion symptoms can affect the quality of life.
Tests such as a gastroscopy (endoscopic examination of the stomach) and ultrasound of the abdomen may not show any specific cause for the symptoms.
‘Gastritis’ is a term often used by the general public to describe indigestion. The medical definition of gastritis refers more specifically to inflammation of the lining of the stomach which is found during gastroscopy.
Some of the causes of gastritis are as a result of smoking, alcohol intake, the use of aspirin or painkillers called non-steroidal anti-inflammatory drugs (NSAIDs), or due to a specific type of bacterial infection known as Helicobacter Pylori.
