Background:
Depression is the most common mental health problem, and frequently associated with physical illnesses. A link between depression, dyspepsia and Helicobacter pylori (H. pylori) infection has previously been reported. However, there is limited data regarding the association between these conditions from sub-Saharan Africa where they are highly prevalent.
Objective:
This study aimed at elucidating the potential associations between depression, dyspepsia and H. pylori infection in Ethiopia.
Methods:
We conducted a community based cross-sectional study involving urban and rural residents aged 13 years or older in Jimma Zone, southwest Ethiopia. A total of 871 participants were evaluated using a structured case reporting format for symptoms of dyspepsia and the patient health questionnaire (PHQ-9) for depression. Additionally, participants were assessed for H. pylori infection using stool antigen and serology tests. A multivariate logistic regression was used to identify the association between depression, dyspepsia and H. pylori infection after controlling for potential confounders.
Results:
The prevalence of PHQ-9 scores indicative of probable case of depression among all participants was 10.9%. The prevalence of probable case of depression among patients who had at least one symptom of dyspepsia was 13.3% (X2 = 15.1 = p-value<0.001), while it was 11.9% (X2 = 1.23, p-value = 0.26) among patients who had H. pylori infection. Out of patients who took medications for their heartburn in the past 30 days, 14.9% (X2 = 3.6, p-value = 0.06) had probable case of depression. Dyspepsia symptoms such as epigastric discomfort (aOR = 2.59, 95%CI = 1.14, 5.87), postprandial fullness (aOR = 1.70, 95%CI = 1.48, 5.51), nausea (aOR = 1.71, 95%CI = 1.04, 2.82) excessive belching (aOR = 0.53, 95%CI = 0.31, 0.92) were associated with probable case of depression. However, being H. pylori test positive, gender, and age were not associated with probable case of depression.
Conclusions:
There was an increased prevalence of probable case of depression among patients who had dyspepsia symptoms and H. pylori infection. Longitudinal studies are needed to examine possible further determinants of association between symptoms of dyspepsia and probable case of depression.

Few clinical manifestations differentiate gastric ulcers from duodenal ulcers. Distinctions in the location, timing, and pain relief are crucial for healthcare providers in differentiating between gastric and duodenal ulcers during clinical assessments.

An acute ulcer, marked by superficial erosion and minimal inflammation, swiftly resolves upon identifying and addressing the underlying cause. In contrast, a chronic ulcer persists, potentially eroding through the muscular wall and forming fibrous tissue.

Clinical manifestations of acute gastritis
The patient with acute gastritis may have a rapid onset of symptoms, such as epigastric pain or discomfort, dyspepsia, anorexia, hiccups, or nausea and vomiting, which can last from a few hours to a few days. Erosive or hemorrhagic gastritis may cause bleeding, which may manifest as blood in vomit or as...
