Peptic ulcers include gastric ulcers, duodenal bulb ulcers, complex ulcers, and so on. It is currently believed that about 80% of peptic ulcers are related to infection with Helicobacter pylori. Additionally, poor dietary and living habits are closely linked to the formation of peptic ulcers, such as excessive smoking and drinking, overeating cold, greasy, spicy, and irritating foods, as well as strong tea, coffee, etc. Moreover, many medications can cause damage to the gastric mucosa, leading to gastric ulcers, such as non-steroidal anti-inflammatory drugs. Furthermore, emotional excitement and major trauma and other stress responses can also lead to acute gastric mucosal lesions, resulting in peptic ulcers.

Can people with peptic ulcers exercise?

The primary cause of peptic ulcers is usually Helicobacter pylori infection, though other factors can also trigger the onset of peptic ulcers, such as tobacco and alcohol irritation, poor dietary habits, and emotional issues. Additionally, excessive fatigue is also one of the causes that can trigger or cause a recurrence of peptic ulcers. Therefore, whether or not a person with peptic ulcers can exercise depends on the specific condition of the illness. If it is an acute active phase or a subacute peptic ulcer that has not fully healed, strict rest is necessary in such cases. If a gastroscopy shows that the ulcer has completely healed, moderate and light activities are permissible, but excessive fatigue should still be avoided.

Treatment of bleeding from peptic ulcers

Gastrointestinal ulcer bleeding may require different management based on the volume of bleeding. With significant bleeding, the condition becomes critical and rapidly changing. Priorities include anti-shock measures, rapid replenishment of blood volume, maintaining a supine position, keeping the airway clear to avoid aspiration during vomiting, providing oxygen if necessary, fasting during active bleeding, closely monitoring the patient's vital signs, immediate blood typing and cross-matching, promptly establishing an effective intravenous infusion pathway, and replenishing blood volume. Medications such as PPIs or H2 receptor antagonists can be used; the former should be chosen for severe bleeding and administered intravenously. About 80% of patients with gastrointestinal ulcer bleeding may stop bleeding without any special treatment, while the remaining patients may experience persistent bleeding or rebleeding. Emergency gastroscopy is crucial to determine if the patient is at high risk of rebleeding or has ongoing bleeding and can include therapeutic endoscopic interventions such as drug injections, electrocoagulation, and the use of hemostatic clips. If endoscopic treatment fails, the gastric and duodenal arteries may be embolized via arterial intervention. If pharmacologic, endoscopic, and interventional treatments cannot control the bleeding, and there is ongoing significant blood loss threatening the patient's life, surgical treatment may be necessary. (Specific medications should be administered under the guidance of a physician.)

The main symptoms of peptic ulcers

Common types of peptic ulcers, including gastric ulcers, duodenal bulb ulcers, complex ulcers, and anastomotic ulcers after gastric resection, share common characteristics and have their own distinct symptoms. Abdominal pain is a usual symptom. The pain from duodenal bulb ulcers tends to be dull, bloating, or blunt, and it is generally more noticeable when hungry. The pain often eases after eating as food neutralizes stomach acid. Sometimes, there is pain at night. If the ulcer is beyond the bulb or is a penetrating ulcer, it often comes with back pain; gastric ulcers primarily manifest as postprandial pain, meaning pain occurring half an hour to an hour after eating, which gradually alleviates; complex ulcers often present with both types of symptoms mentioned above. As peptic ulcers are often associated with excessive stomach acid, symptoms like acid reflux, heartburn, and nausea are common.

Symptoms of peptic ulcer

Peptic ulcers typically include gastric ulcers, duodenal bulb ulcers, and complex ulcers, among others, all of which feature upper abdominal pain. For gastric ulcers, the pain is generally located below the xiphoid process or in the upper left abdomen, primarily occurring after meals and often accompanied by symptoms such as abdominal bloating and acid reflux. Duodenal bulb ulcers usually present as hunger-like pain in the upper abdomen, which can be alleviated by eating and may include nighttime pain, often with significant acid reflux and heartburn. These can be definitively diagnosed via gastroscopy. Additionally, many elderly individuals may develop gastric ulcers after taking nonsteroidal anti-inflammatory drugs, often without significant pain, typically requiring a gastroscopy for accurate diagnosis.

Characteristics of pain in peptic ulcers

Peptic ulcers include gastric ulcers, duodenal bulb ulcers, and gastro-duodenal composite ulcers. The common characteristic of peptic ulcers is upper abdominal pain, which tends to be recurrent, periodic, and regular. For duodenal bulb ulcers, the pain is primarily located above and to the right of the navel, mainly manifesting as hunger pain in the upper abdomen, which can be alleviated after eating, accompanied by nocturnal pain. Sometimes, bulb ulcers can cause back pain. Gastric ulcers are mainly located above and to the left of the navel, primarily characterized by postprandial pain.
