Short bowel syndrome
Short bowel syndrome (SBS) is a condition that can occur when a significant portion of the small intestine is removed or damaged, resulting in malabsorption of nutrients and fluid. The small intestine is responsible for absorbing most of the nutrients and water from food, and a loss of more than 60% of its length can lead to SBS.
-
- Diarrhea: The remaining small intestine may not be able to absorb enough water from the food, leading to frequent and watery bowel movements.
- Malnutrition: Without enough nutrients being absorbed, the body may not have enough energy to function properly, leading to weight loss and weakness.
- Dehydration: The loss of fluid through diarrhea can lead to dehydration, which can cause symptoms such as dizziness, lightheadedness, and fainting.
- Fatigue: Malnutrition and dehydration can lead to fatigue and a lack of energy.
- Abdominal pain: The remaining small intestine may become irritated or inflamed due to the increased workload, leading to pain and discomfort.
-
- Nutritional support: This may include supplements, fortified foods, or parenteral nutrition (nutrition delivered directly into the bloodstream) to provide the necessary nutrients and calories.
- Medications: Medications may be used to manage symptoms such as diarrhea or abdominal pain.
- Surgery: In some cases, additional surgery may be needed to reconstruct the digestive system or reduce the workload on the remaining small intestine.
- Lifestyle changes: Making dietary changes such as eating smaller, more frequent meals, avoiding high-fat or high-fiber foods, and drinking plenty of fluids can help manage symptoms and prevent complications.
The clinical picture of short bowel syndrome (SBS) can vary widely depending on the extent and location of the small intestine that is affected. Some common symptoms and complications associated with SBS include:
- Diarrhea: The remaining small intestine may not be able to absorb enough water from the food, leading to frequent and watery bowel movements.
- Malabsorption: Without enough nutrients being absorbed, the body may not have enough energy to function properly, leading to weight loss, malnutrition, and weakness.
- Dehydration: The loss of fluid through diarrhea can lead to dehydration, which can cause symptoms such as dizziness, lightheadedness, and fainting.
- Fatigue: Malnutrition and dehydration can lead to fatigue and a lack of energy.
- Abdominal pain: The remaining small intestine may become irritated or inflamed due to the increased workload, leading to pain and discomfort.
- Steatorrhea: Without enough bile salts being produced in the liver, the body may not be able to digest fats properly, leading to greasy, foul-smelling stools (steatorrhea).
- Vitamin and mineral deficiencies: Without enough nutrients being absorbed, the body may become deficient in vitamins and minerals such as iron, calcium, vitamin B12, and vitamin D.
- Bacterial overgrowth: Without enough nutrients being absorbed, bacteria in the small intestine may overgrow, leading to symptoms such as bloating, gas, and abdominal pain.
- Delayed gastric emptying: In some cases, SBS can lead to delayed gastric emptying (gastroparesis), which can cause symptoms such as nausea, vomiting, and bloating.
- Intestinal obstruction: In severe cases of SBS, the remaining small intestine may become obstructed due to scar tissue or adhesions (bands of tissue that connect organs), leading to symptoms such as abdominal pain, bloating, and vomiting.

The treatment of short bowel syndrome (SBS) aims to manage symptoms, prevent complications, and provide adequate nutrition. Here are some treatment options:
- Nutritional management: This involves providing the body with enough nutrients through a variety of sources, such as oral supplements, enteral nutrition (tube feeding), and parenteral nutrition (intravenous feeding). The type of nutrition will depend on the extent and location of the small intestine that is affected.
- Medications: Medications can be used to manage symptoms such as diarrhea, malabsorption, and bacterial overgrowth. For example, loperamide can be used to slow down bowel movements, and antibiotics can be used to treat bacterial overgrowth.
- Surgery: In some cases, surgery may be necessary to correct the underlying cause of SBS or to manage complications such as intestinal obstruction. For example, intestinal resection (removal of part of the small intestine) may be necessary to remove damaged or diseased tissue.
- Fluid management: Dehydration is a common complication of SBS, so it's important to replace fluids lost through diarrhea and vomiting. This can be done through oral rehydration solutions or intravenous fluids.
- Electrolyte management: Electrolyte imbalances are common in SBS due to dehydration and malabsorption. Electrolytes such as potassium, magnesium, and calcium may need to be replaced through supplements or intravenous fluids.
- Vitamin and mineral supplements: Without enough nutrients being absorbed, the body may become deficient in vitamins and minerals such as iron, calcium, vitamin B12, and vitamin D. Supplements may be necessary to prevent deficiencies.
- Psychological support: Living with SBS can be challenging both physically and emotionally, so it's important to provide psychological support and counseling to help manage the condition.
- Follow-up care: Regular follow-up care with a healthcare provider is important to monitor symptoms, nutritional status, and any complications that may arise. Adjustments to treatment may be necessary over time as the condition evolves.
Short bowel syndrome (SBS) can have various causes, some of which include:
- Surgical resection: This is the most common cause of SBS, resulting from the removal of a significant portion of the small intestine due to disease or injury. Conditions that may require surgical resection include Crohn's disease, ulcerative colitis, intestinal cancer, volvulus (twisting of the intestine), and intestinal obstruction.
- Intestinal diseases: Some intestinal diseases can cause damage to the small intestine, leading to SBS. Examples include Crohn's disease, celiac disease, and lymphangiectasia (a condition that causes swelling and damage to the lymphatic vessels in the intestine).
- Congenital malformations: Some people are born with congenital malformations of the small intestine, such as atresia (blockage) or malrotation (twisting), which can lead to SBS.
- Radiation therapy: Radiation therapy used to treat cancer in the abdomen or pelvis can damage the small intestine, leading to SBS.
- Infections: Infections such as bacterial overgrowth, viral gastroenteritis, or parasitic infections can cause inflammation and damage to the small intestine, leading to SBS.
- Trauma: Trauma to the abdomen or pelvis can cause damage to the small intestine, leading to SBS.
The severity and symptoms of SBS depend on the extent and location of the small intestine that is affected, as well as other factors such as age, overall health, and nutritional status.
