Introduction
In general, common symptoms of pancreatitis include persistent upper abdominal pain, nausea and vomiting, abdominal bloating, fever, and referred pain to the lower back. If any of these symptoms occur, it is advisable to seek timely medical evaluation and treatment at a reputable hospital. Additionally, as the condition worsens, patients may experience decreased appetite and fatigue. In daily life, maintaining regular, balanced meals—and avoiding overeating or binge drinking—is essential.
Generally, common symptoms of pancreatitis include persistent upper abdominal pain, nausea and vomiting, abdominal distension, fever, and referred pain to the lower back or lumbar region. If any of these symptoms occur, it is advisable to seek prompt medical evaluation and treatment at a reputable hospital. A detailed analysis follows:
1. Persistent Upper Abdominal Pain
Persistent upper abdominal pain is the classic initial presentation of pancreatitis, typically manifesting as a continuous dull or severe pain. Inflammation, congestion, and edema of pancreatic tissue stimulate surrounding nerves, while inflammatory exudates irritate the peritoneum, resulting in deep-seated abdominal pain. Discomfort tends to worsen after consuming high-fat meals.
2. Nausea and Vomiting
During pancreatitis, gastrointestinal digestive function becomes disrupted, triggering spasms of gastrointestinal smooth muscle and causing recurrent nausea and vomiting. Vomitus usually consists of gastric food residue or gastric secretions. Unlike typical gastrointestinal discomfort, abdominal pain does not subside after vomiting.
3. Abdominal Distension
Pancreatic inflammation impairs normal gastrointestinal motility, hindering the expulsion of intestinal gas and leading to its accumulation within the abdominal cavity—causing bloating and abdominal rigidity. This distension persists alongside ongoing inflammation and may severely impair normal eating in advanced cases.
4. Fever
Local pancreatic inflammation activates the body’s immune defense mechanisms; inflammatory mediators enter the systemic circulation, inducing elevated body temperature. Mild cases often present with low-grade fever, whereas progressive inflammation may lead to sustained fever.
5. Referred Pain to the Lumbar Region and Back
The pancreas lies retroperitoneally, adjacent posteriorly to lumbar and dorsal nerve structures. As inflammation intensifies, it stimulates these nerves, producing aching or painful sensations in the lower back and lumbar area. Such pain may be slightly alleviated by bending forward or flexing the knees.
In addition, disease progression may cause loss of appetite and generalized fatigue. In daily life, maintaining regular dietary habits, avoiding overeating or binge eating, limiting intake of high-fat and high-oil foods, and abstaining from alcohol are essential measures to reduce pancreatic burden and lower the risk of pancreatitis.
