The Primary Symptoms of High Small Bowel Obstruction Beyond Abdominal Pain

Nausea and vomiting are among the key symptoms associated with high small bowel obstruction, aside from abdominal pain. Patients may also experience bleeding, passage of gas, and inability to pass stool, all of which are typical signs of bow obstruction. When the blockage occurs in the upper part of the small intestine, it significantly impacts the upper digestive tract, often leading to frequent and severe vomiting, especially after eating.

Because digestive fluids accumulate above the obstruction, this symptom becomes more pronounced and is considered a hallmark of high intestinal blockages. As the condition progresses, abdominal distension may also become noticeable, particularly if the obstruction is complete or prolonged.

It's crucial for patients to undergo diagnostic tests such as X-rays, CT scans, or contrast studies to determine not only the presence of an obstruction but also its underlying cause. Possible causes include adhesions, tumors, or conditions like gastric phytobezoar, where indigestible material—often from consuming foods like persimmons—forms a mass that blocks the intestines.

Once the cause has been identified, appropriate treatment can be initiated. In most cases, consultation with a general surgeon or a specialist in gastrointestinal surgery is necessary to evaluate whether surgical or non-surgical intervention is required. Early diagnosis and management are essential to prevent complications such as bowel ischemia or perforation.
