Atrophic gastritis Archives

Tag: Atrophic gastritis

Atrophic gastritis is a process of chronic inflammation of the gastric mucosa of the stomach, leading to a loss of gastric glandular cells and their eventual replacement by intestinal and fibrous tissues. There is an autoimmune version.

Linked to Type 1 Gastric NETs, the most common type of stomach (gastric) neuroendocrine tumour accounting for between 70 and 80% of all Gastric NETs.

Experimental drug for Gastric NET – Netazepide

Clinical Trials and Research, TreatmentAtrophic gastritis, Clinical trial, Gastric NET, Gastrin, Netazepide, Neuroendocrine tumour (NET)

Update Apr 2026. Nothing has been published about this trial for some years. I spoke to a leading UK Gastroenterologist who thinks it has been quietly dropped. I will keep this blog open for a year or more just in case anything crops up. Gastric NETs When I wrote my post entitled "Spotlight on Gastric Neuroendocrine Neoplasms", I explained what these were with some emphasis on the association with hypergastrinemia (elevated fasting serum gastrin levels) with Type 1 and 2 gNETs being differentiated by the settings in which this occurs. This oversecretion is not the same as so called carcinoid…

A spotlight on Gastric Neuroendocrine Neoplasms (based on 2026 WHO Classification)

A spotlight on NENs - Types, Awareness, Patient Advocacy, Spotlight on NENs - Types Series, TreatmentAtrophic gastritis, Gastric NET, Gastrin, Gastrin pH, Gastrinoma, Hypergastrinemia, Neuroendocrine carcinoma (NEC), Neuroendocrine neoplasm (NEN), Neuroendocrine tumour (NET), Pernicious anaemia, Proton pump inhibitors (PPI)

What are Gastric NENs Unlike other anatomical types, the word Gastric is used to indicate a tumour (NET) or carcinoma (NEC) in the stomach. The stomach lies at the bottom of your oesophagus and connects to the first part of the small intestine (the duodenum). Clearly a key part of the gastrointestinal system, it processes food on its journey downwards. The stomach produces strong acid. This kills many microorganisms that might have been swallowed along with the food. It also contains special chemicals called enzymes. These are important for breaking down the food so it can be absorbed by the…

Ever wonder what caused your Neuroendocrine Cancer?

OPINION. When you're diagnosed, you go through a whole host of emotions. It's not just the initial shock, the disbelief, the anxiety and morbid worry produced by the words "you have cancer", it's other stuff such as anger and denial. With the latter, the denial normally wears off as you finally accept the predicament.In hindsight, the anger is interesting because there can be a mixture of thoughts including "why me", "what could I have done to head this off"; and would you believe I was even angry that my diagnosis was going to affect my performance at work and even…
