Peptic Ulcer Disease, commonly called PUD, refers to open sores that develop on the inner lining of the stomach, known as a gastric ulcer, or the upper part of the small intestine, known as a duodenal ulcer. In clinical practice across Nigeria, midwives frequently encounter patients presenting with chronic epigastric pain attributed to this condition. While global medical literature heavily highlights bacterial infection and non-steroidal anti-inflammatory drugs as primary drivers, local realities heavily compound the disease burden.
Economic pressures, widespread self-medication with over-the-counter analgesics, and dietary habits rich in highly spiced foods all worsen mucosal injury. Many patients cope with early abdominal discomfort by taking potent analgesics from local chemist shops without a prescription, inadvertently accelerating gastric mucosal damage. Recognizing these local socioeconomic and cultural factors helps midwives provide contextually relevant care and education.
The stomach and duodenum are naturally designed to withstand a harsh chemical environment because they produce powerful protective mechanisms. Parietal cells secrete hydrochloric acid to break down food, while chief cells release pepsinogen, an enzyme activated by acid into pepsin for protein digestion. To prevent this acidic juice from digesting the stomach itself, specialized surface cells secrete a thick, alkaline mucus layer laced with bicarbonate.
A delicate balance exists between aggressive factors like acid and pepsin, and defensive factors like mucus, bicarbonate, and rich local blood flow. When mucosal blood flow drops or protective factors fail, acid breaches the barrier, causing cellular destruction and ulcer formation.
Two major culprits account for the vast majority of all peptic ulcer cases seen globally and locally:
Ulcer formation is fundamentally a mismatch between aggressive forces and mucosal defense. When *H. pylori* infects the mucosa, bacterial toxins and the body's immune response cause localized tissue inflammation, known as gastritis. The bacteria weaken the tight junctions between epithelial cells, making the tissue vulnerable to acid penetration.
Similarly, when NSAIDs suppress mucosal prostaglandins, local blood flow diminishes. Deprived of oxygen and nutrients, the superficial epithelial cells die off rapidly. Once the mucosal barrier is breached, hydrochloric acid and pepsin rush into the exposed submucosa, digesting local tissue, causing bleeding, and producing a crater-like wound known as a peptic ulcer.
Patients with peptic ulcer disease typically present with a burning, gnawing, or aching pain located in the epigastric region. A helpful clinical distinction exists between the two main types:
Associated symptoms include bloating, excessive belching, nausea, and vomiting. To confirm diagnosis, clinicians rely heavily on upper gastrointestinal endoscopy, which allows direct visualization of the ulcer crater and tissue biopsy for *H. pylori*. Non-invasive tests include the urea breath test and stool antigen tests.
Treatment goals for peptic ulcer disease focus on relieving pain, healing the crater, and preventing recurrence by targeting the underlying cause.
Untreated or severe peptic ulcer disease can lead to life-threatening emergencies that require prompt surgical and medical intervention:
Midwives play a vital role in managing patients with peptic ulcer disease through holistic care and targeted health education. The nursing care plan prioritizes managing acute pain, monitoring for signs of internal bleeding, and assessing nutritional status.
Midwives must educate patients on completing their full course of prescribed antibiotics if *H. pylori* is present, rather than stopping when pain subsides. Patients should be strictly advised to avoid routine use of non-prescription anti-inflammatory drugs and to seek safe alternatives like paracetamol under medical supervision. Dietary counseling focuses on eating balanced, regular meals while avoiding known personal irritants such as excessive caffeine, alcohol, and very hot, spicy foods.
