Esomeprazole, sold under the brand name Nexium [or Neksium] among others, [2] is a medication which reduces stomach acid. [11] It is used to treat gastroesophageal reflux disease, peptic ulcer disease, and Zollinger–Ellison syndrome. [11] [12] Its effectiveness is similar to that of other proton pump inhibitors (PPIs).

Cancer of the stomach is difficult to cure unless it is found at an early stage (before it has begun to spread). Unfortunately, because early stomach cancer causes few symptoms, the disease is usually advanced when the diagnosis is made. [80] Treatment for stomach cancer may include surgery, [81] chemotherapy, [13] or radiation therapy. [82]
Stomach cancer can cause nausea, vomiting, diarrhoea, constipation, and unexplained weight loss. [70] Gastric polyps are adenomas that are usually asymptomatic and benign, but may be the cause of dyspepsia, heartburn, bleeding from the stomach, and, rarely, gastric outlet obstruction. [61] [71] Larger polyps may have become cancerous. [61]

Nausea and vomiting may have a number of causes in people with cancer. [7] While more than one cause may exist in the same person stimulating symptoms via more than one pathway, the actual cause of nausea and vomiting may be unknown in some people.

Acid secretion by the human stomach results in a median diurnal pH of 1.4. This very large (>10 6 -fold) H + gradient is generated by the gastric H + /K + ATPase which is an ATP-driven proton pump. Hydrolysis of one ATP molecule is used to catalyse the electroneutral exchange of two luminal potassium ions for two cytoplasmic protons through the ...
