Bowel Obstruction
Bowel Obstruction
Bowel obstruction is a condition in which there is a partial or complete blockage of the normal passage of intestinal contents through the small or large intestine. It occurs when food, fluids, and gas cannot pass normally through the digestive tract. Scar tissue from previous abdominal surgery, hernias, tumours, intestinal inflammation, or severe constipation can cause bowel obstruction. The expert team at Manipal Hospitals provides a multidisciplinary approach to bowel obstruction management.

Bowel obstruction symptoms may include severe abdominal pain, abdominal swelling, nausea, vomiting, constipation, and inability to pass gas. Some patients may also experience loss of appetite and abdominal cramping that results from the accumulation of intestinal contents.
How We Diagnose Bowel Obstruction
Bowel obstruction diagnosis begins with reviewing the medical history and performing a physical examination to assess abdominal tenderness, distension, and bowel sounds. Doctors may suggest imaging tests such as abdominal X-rays, ultrasounds, or CT scans to identify the location and severity of the obstruction. To evaluate dehydration, infection, or electrolyte imbalance associated with the condition, blood tests may also be recommended.
Treatment Options
Bowel obstruction treatment depends on the cause and severity of the obstruction. Treatment may include intravenous fluids, decompression with a nasogastric tube, and medications to relieve symptoms. If the obstruction does not resolve or complications occur, surgery may be required.
What to Expect
At Manipal Hospitals, patients diagnosed with bowel obstruction receive prompt evaluation and stabilisation to prevent further complications. Initial management aims to relieve symptoms and correct dehydration. Patients are admitted to the hospital for close monitoring, where intravenous fluids are administered to help restore hydration and electrolyte balance.
In some cases, doctors may insert a nasogastric tube through the nose into the stomach to remove excess gas and fluid buildup in the digestive tract. This procedure provides symptomatic relief while allowing the intestines to rest. If the obstruction is partial and caused by inflammation or temporary bowel slowing, conservative management and observation may allow the blockage to resolve without surgery.
If the obstruction is complete or caused by a tumour, hernia, or severe adhesions, surgical treatment may be necessary. Surgeons may perform minimally invasive or open procedures depending on the patient's condition.
After treatment, doctors closely monitor bowel function, hydration status, and nutritional recovery. Most patients can gradually resume oral intake once bowel activity returns. With early diagnosis and appropriate care, many patients can recover well and regain normal digestive function.

FAQs
-
Can bowel obstruction occur even without a history of previous surgery?
Yes. Although scar tissue after surgery is a common cause, bowel obstruction can also occur in people without prior surgery. Hernias, intestinal tumours, inflammatory bowel disease, volvulus, and impacted stool may also block the normal movement of intestinal contents.
-
What complications can occur if bowel obstruction is untreated?
If untreated, bowel obstruction may lead to intestinal perforation, severe abdominal infection, dehydration, and electrolyte imbalance. It may also damage intestinal tissues due to reduced blood supply. Prompt treatment can significantly reduce these risks.
-
How is bowel obstruction treated without surgery?
Partial bowel obstruction may sometimes be managed with observation in the hospital. Intravenous fluids, bowel rest, and nasogastric tube decompression to relieve pressure within the digestive tract may help manage the condition. Doctors monitor patients to ensure the obstruction resolves safely.
-
What are the most common causes of bowel obstruction?
Bowel obstruction causes include adhesions formed after abdominal surgery, hernias, tumours blocking the intestinal passage, and severe constipation. Inflammatory bowel diseases can also cause bowel obstruction by narrowing or swelling the intestinal tissues.
-
When should someone seek medical attention for suspected bowel obstruction?
It is important to seek medical attention if a person experiences severe abdominal pain, persistent vomiting, abdominal swelling, or inability to pass stool or gas. Early evaluation helps prevent complications such as intestinal perforation or infection.
