Studies have shown a high occurrence of mental disorders, notably anxiety and depression, amongst patients with dyspepsia; however, there is little evidence to prove causation. Organic Dyspepsia
Esophagitis
Esophagitis is an inflammation of the esophagus, most commonly caused by gastroesophageal reflux disease (GERD). It is defined by the sensation of "heartburn" or a burning sensation in the chest as a result of inappropriate relaxation of the lower esophageal sphincter at the site where the esophagus connects to the stomach. It is often treated with proton pump inhibitors. If left untreated, the chronic damage to the esophageal tissues poses a risk of developing cancer. A meta-analysis showed risk factors for developing GERD included age equal to or greater than 50, smoking, the use of non-steroid anti-inflammatory medications, and obesity. Gastritis
Common causes of gastritis include peptic ulcer disease, infection, or medications. Peptic Ulcer Disease
Gastric and/or duodenal ulcers are the defining feature of peptic ulcer disease (PUD). PUD is most commonly caused by an infection with H. pylori or NSAID use. Helicobacter pylori (H.pylori) infection
The role of H. pylori in functional dyspepsia is controversial, and treatment for H. pylori may not lead to complete improvement of a patients dyspepsia. However, a recent systemic review and meta-analysis of 29 studies published in 2022 suggests that successful treatment of H. pylori modestly improves indigestion symptoms. Pancreatobiliary Disease
These include cholelithiasis, chronic pancreatitis, and pancreatic cancer. Duodenal micro-inflammation
Duodenal micro-inflammation caused by an altered duodenal gut microbiota, reactions to foods (mainly gluten proteins) or infections may induce dyspepsia symptoms in a subset of people.
Brachymetacarpia is a medical condition in which the metacarpals of the hands are shortened, the foot equivalent to this condition is brachymetatarsia. This condition is one of the causes of brachydactyly.
