Intestinal obstruction
Symptoms of intestinal obstruction
For symptoms of intestinal obstruction, the typical manifestations are abdominal pain, bloating, vomiting, and cessation of passing gas or stool. Most people may experience several of these symptoms; however, the severity of the symptoms depends on the location and condition of the obstruction. Once symptoms of intestinal obstruction occur, it is necessary to refrain from eating and then carry out appropriate examinations. Identifying the cause of the obstruction is crucial. If the obstruction is caused by tumor-related factors, surgical treatment should be considered based on a comprehensive assessment. If the obstruction is due to adhesions, conservative treatment methods should be adopted where possible.
Causes of intestinal obstruction
Generally, the basic causes of intestinal obstruction can be divided into three categories. The most common is mechanical intestinal obstruction, which mainly includes blockage of the intestinal lumen, such as large fecal masses or corresponding foreign objects, and even parasites. The second type is compression of the intestinal tube, which can be caused by adhesions leading to torsion of the intestine or compression by tumors, and congenital inflammatory strictures and tumors can cause mechanical intestinal obstruction. The second major category is dynamic intestinal obstruction, which is primarily due to weakened peristaltic ability of the intestine, resulting in paralytic intestinal obstruction. This condition can be improved by adjusting intestinal function disorders or treating intestinal spasms. The third type is intestinal obstruction caused by vascular issues in the intestines, most commonly thrombosis of the mesentery or compression causing vascular disorders of the intestines.
How long to fast for intestinal obstruction
Intestinal obstruction and the barrier to the passage of intestinal contents can lead to intestinal obstruction, typically characterized by abdominal pain, bloating, cessation of passing gas and stools, and in cases of high intestinal obstruction, it may also involve nausea and vomiting. How long fasting should be continued in the case of intestinal obstruction depends on whether the patient has resumed passing gas and stools, as well as whether symptoms such as abdominal pain, bloating, nausea, and vomiting have subsided. If the patient's abdominal pain and bloating have mostly subsided, passing gas and stools have resumed, and there is no bloody stool or symptoms of nausea and vomiting, then a gradual reintroduction of a liquid diet can be started. If abdominal pain and bloating do not worsen, and there is passing gas and stools, then a transition to a semi-liquid diet until a normal diet is resumed can be made. Therefore, the duration of fasting for intestinal obstruction should be determined based on the effectiveness of the treatment for the obstruction.
Do intestinal obstructions cause vomiting?
The typical four major symptoms of intestinal obstruction are pain, vomiting, bloating, and constipation. Vomiting refers to the urge to vomit; however, it does not mean that every patient with an obstruction must exhibit symptoms of vomiting, as the symptoms vary depending on the location of the obstruction. Obstructions can be categorized into lower and upper types. Upper obstruction may present more apparent vomiting symptoms, while lower obstruction might lead to significant bloating but less obvious vomiting. Therefore, vomiting is not a necessary symptom for the treatment of intestinal obstruction, but it can help in assessing the condition of the obstruction.
Can you fart with intestinal obstruction?
When the contents of the intestines cannot normally pass through the intestinal tract and be expelled from the body, it is called intestinal obstruction. The main clinical manifestations include abdominal pain, abdominal distension, vomiting, and the cessation of bowel movements and gas passage through the anus. Clinically, some cases of partial intestinal obstruction can still pass gas, and some cases of high intestinal obstruction may also allow gas accumulation below the blockage to be expelled through the anus. However, the ability to pass gas does not mean that the patient's condition has improved; continuous treatment and observation are still necessary.
What is intestinal obstruction?
Intestinal obstruction refers to a blockage condition caused by various factors leading to intestinal obstruction, compression, and torsion, which prevents the normal passage of intestinal contents through the intestine. This is collectively referred to as intestinal obstruction. Intestinal obstruction can be divided into three categories based on the cause: first, mechanical intestinal obstruction; second, dynamic intestinal obstruction; and third, vascular intestinal obstruction. The main clinical symptoms of intestinal obstruction are abdominal pain, abdominal distension, vomiting, and cessation of gas and feces from the anus. Clinically, intestinal obstruction can be treated conservatively or surgically.
Is intestinal obstruction dangerous?
Whether intestinal obstruction is dangerous depends on the actual individualized level. If the obstruction has progressed to symptoms of peritonitis, and if intestinal necrosis cannot be ruled out, not performing timely exploratory laparotomy surgery could potentially endanger the patient's life. However, if it is just a mild incomplete obstruction, with signs of passing gas and stools, and the patient’s abdominal symptoms are not pronounced, and related examinations are not concerning, then the risk to the patient might be relatively smaller. Therefore, in such cases, it is not possible to generalize, and decisions need to be made based on the individual situation.
Early symptoms of intestinal obstruction
What are the early symptoms of intestinal obstruction? For intestinal obstruction, the symptoms that appear in the early stages vary depending on the location of the obstruction. If it is a high-level obstruction, the main early symptoms are nausea and vomiting. If it is a low-level obstruction, abdominal distension is more prominent early on, and nausea and vomiting are less common. Additionally, the cause of the obstruction also leads to different symptoms. For instance, if the obstruction is simply due to adhesions in the abdominal cavity, the early symptoms may include poor appetite or nausea and vomiting. If it is caused by tumors in the digestive tract, early symptoms might include abdominal bloating, difficulty defecating, bloody stools, or changes in the characteristics of the stool, among others.
What can you eat with intestinal obstruction?
Intestinal obstruction, as the name implies, is when the contents within the intestines are blocked. Generally, patients are not allowed to eat, but this depends on the progress of the condition and whether there is a need for food or water intake. In some cases of incomplete obstruction, it is possible to consume a small amount of liquid or residue-free diet. However, for cases of obstruction with clear symptoms and severe conditions, patients are not permitted to eat. They might even require gastrointestinal decompression, which involves the insertion of a gastric tube for further treatment.
Does intestinal obstruction expel gas?
Intestinal obstruction typically refers to the inability of the intestinal contents to pass through the intestines and be expelled from the body normally. Common clinical manifestations include abdominal pain, bloating, vomiting, and cessation of bowel movements and passing gas. However, in some cases, such as partial intestinal obstruction or high intestinal obstruction, gas can still be expelled from the anus below the obstruction site. This means that some intestinal obstructions can still pass gas, but the ability to pass gas does not mean the patient has recovered.
