Introduction
In general, a persistent feeling of incomplete bowel movements accompanied by nausea may be caused by conditions such as functional dyspepsia, ulcerative colitis, or acute gastroenteritis. Patients should identify the underlying cause and receive appropriate treatment. It is recommended that patients consume more fresh vegetables and fruits in daily life and chew food thoroughly during meals, which not only aids nutrient absorption but also promotes gastric emptying.
Generally, the sensation of constantly needing to defecate accompanied by nausea may be caused by conditions such as functional dyspepsia, ulcerative colitis, or acute gastroenteritis. Patients should identify the underlying cause and receive appropriate treatment. Specific analyses are as follows:
1. Functional Dyspepsia
Functional dyspepsia is a non-organic disorder caused by multiple factors, including psychological stress, immune system abnormalities, and gastrointestinal hypersensitivity. In this condition, gastrointestinal motility and digestive function decrease, impairing food digestion and absorption. As undigested food accumulates in the gastrointestinal tract, symptoms such as nausea, persistent urge to defecate, and bloating may occur. Prokinetic medications such as domperidone tablets, mosapride citrate tablets, or itopride hydrochloride tablets may be used under medical guidance. Additionally, patients should relax mentally and avoid prolonged periods of emotional stress.
2. Ulcerative Colitis
Ulcerative colitis is a chronic nonspecific inflammation affecting the mucosa of the colon and rectum. Chronic inflammatory factors irritate the intestinal mucosa, leading to ulcerative lesions and reduced capacity for digestion and absorption, which can result in symptoms like nausea and vomiting. When the rectal mucosa is stimulated, patients may experience tenesmus—the urgent but ineffective need to defecate. First-line treatment typically includes aminosalicylate preparations such as sulfasalazine enteric-coated tablets or olsalazine sodium capsules, which must be used under medical supervision.
3. Acute Gastroenteritis
Acute gastroenteritis occurs when consuming contaminated food or experiencing abdominal chilling, leading to bacterial infection in the intestines. The resulting inflammation irritates the intestinal mucosa, increasing intestinal motility and causing symptoms such as abdominal pain, nausea, and vomiting. A frequent urge to defecate may also occur, although there may not be actual stool to pass. Under medical guidance, patients can take medications such as levofloxacin hydrochloride tablets or hydrotalcite (aluminum magnesium carbonate) tablets to control the condition and relieve symptoms. Additionally, dietary adjustments are essential: avoid overeating or binge eating; maintain regular meal times with moderate portions—about 70–80% fullness per meal. Also avoid spicy, greasy, raw, cold, hard, or overly dry foods that are difficult to digest.
Besides the above three causes, other conditions such as gastritis, intestinal obstruction, or colon cancer may also be responsible. It is recommended to seek timely medical evaluation and receive symptomatic treatment under professional guidance.
