What causes bowel problems?
Bowel problems have a wide variety of causes, including structural abnormalities, infections, inflammations, surgical complications, medication use, and lifestyle factors such as diet.
Structural causes of bowel problems
Structural abnormalities of the bowel can be present at birth, acquired throughout life, or those caused by surgery. Examples include:
- Developmental abnormalities that are present at birth
- Intestinal surgery that removes part of the intestines or causes complications, such as scarring and adhesions
- Malrotation (incorrect positioning of the bowel that develops during fetal development)
- Short bowel syndrome, caused by surgical removal of part of the small intestine
Causes of physical obstructions of the bowel
Causes of physical blockage of the bowel include:
- Adhesions (scar tissue from previous surgery or infections)
- Diverticulitis (inflammation of small pouches of the bowel)
- Foreign bodies (bezoar, hair ball)
- Impacted feces
- Intussusception (sliding of part of the intestine into an adjacent part, like a collapsing telescope)
- Tumors (whether arising from the intestines or pressing on them)
- Volvulus (twisting of the intestines)
Infections and inflammation of the bowel
Infections and inflammatory disorders of the bowel include:
- Bacterial, fungal, parasitic or viral infections
- Inflammatory bowel disease, including Crohn’s disease and ulcerative colitis
- Gastroenteritis (inflammation of the gastrointestinal tract, due to numerous causes)
Other causes of bowel problems
Other causes of bowel problems include:
- Celiac disease (severe sensitivity to gluten from wheat and other grains that causes intestinal damage)
- Irritable bowel syndrome (IBS; digestive discomfort that does not cause intestinal damage or serious disease)
- Meckel’s diverticulum (congenital, abnormal pouch near the lower end of the small intestine)
- Polyps or benign growths
- Trauma to the abdomen
Serious or life-threatening causes of bowel problems
In some cases, bowel problems may be a symptom of a serious or life-threatening condition. These include:
- Bowel obstruction
- Mesenteric vessel obstruction
Questions for diagnosing the cause of bowel problems
To diagnose your condition, your doctor or licensed health care practitioner will ask you several questions related to your bowel problems including:
- How long have you felt the symptoms?
- When did you first notice them?
- Where do you feel pain?
- Is the pain relieved by defecating?
- Do you have any bleeding from the anus or rectum?
- Have you experienced appetite loss or weight loss?
- Do you have any other symptoms?
- What medications are you taking?
What are the potential complications of bowel problems?
Because bowel problems can be due to serious diseases, failure to seek treatment can result in serious complications and permanent damage. Once the underlying cause is diagnosed, it is important for you to follow the treatment plan that you and your health care professional design specifically for you to reduce the risk of potential complications including:
- Abdominal abscess
- Dehydration and electrolyte imbalance due to long-term diarrhea
- Fistula (abnormal hole or tube between organs or tissues, which can become seriously infected and cause other problems)
- Fluid and electrolyte disorders
- Nutritional deficiencies
- Osteoporosis (thinning and weakening of the bones)
- Poor quality of life
- Spread of cancer
- Spread of infection
- Stricture (narrowing) in the colon
- Unintended weight
