Overview

Crohn Disease
Crohn disease is a chronic inflammatory bowel disease that can cause inflammation anywhere along the digestive tract, although the small intestine and beginning of the large intestine are commonly affected. Symptoms may include persistent diarrhea, abdominal pain, weight loss, fatigue, reduced appetite, and sometimes fever. The disease can alternate between periods of active symptoms and remission. Inflammation may extend through the bowel wall and lead to complications such as narrowing, fistulas, abscesses, or nutritional deficiencies.
Bronchiectasis
Bronchiectasis is a long-term lung condition in which the airways become permanently widened and damaged. Damaged airways do not clear mucus normally, allowing mucus and bacteria to accumulate and causing repeated lung infections. Symptoms may include a persistent cough, large amounts of mucus or phlegm, shortness of breath, wheezing, chest discomfort, fatigue, and repeated respiratory infections.

Diagnosis

Crohn Disease
Crohn disease is diagnosed using a combination of medical history, physical examination, laboratory tests, stool testing, endoscopy, and imaging. Blood tests may identify anemia or inflammation, while stool tests can help assess intestinal inflammation and exclude infections. Colonoscopy with examination of the terminal ileum and biopsy is commonly important. Cross-sectional imaging such as MRI or CT enterography may evaluate the small intestine and complications. No single test establishes Crohn disease in every patient.
Bronchiectasis
Bronchiectasis is evaluated using symptoms, medical history, and a physical examination. A chest CT scan is commonly used because it can show widening and structural damage of the airways. Lung function tests can measure breathing ability. Sputum may be tested to identify bacteria or other organisms causing infection. Additional blood tests may be used to look for an underlying cause.

Prevention

Crohn Disease
There is no guaranteed way to prevent Crohn disease because its causes are complex and include genetic and immune factors. Not smoking is particularly important because smoking can increase disease activity and complications. People with Crohn disease can reduce complications through regular medical follow-up, appropriate treatment, nutritional support, and monitoring for deficiencies. Individual food triggers can be identified with professional guidance. Vaccination and preventive health care are also important for people receiving medicines that affect the immune system.
Bronchiectasis
Preventing respiratory infections and treating them promptly can help reduce lung damage that may lead to bronchiectasis. Recommended vaccinations, including those against influenza and pneumococcal disease, can help protect against important infections. Avoiding tobacco smoke and other lung irritants is important. People with an underlying condition should follow treatment plans designed to maintain airway clearance and reduce infections.

Risk Factors

Crohn Disease
Risk factors for Crohn disease include a family history of inflammatory bowel disease, certain genetic factors, smoking, and some environmental influences. The disease can occur at any age but is often diagnosed in adolescents and young adults. People with certain immune-related conditions may have increased susceptibility. Smoking is particularly important because it can increase disease activity and complications. Diet does not directly cause Crohn disease, although individual foods may worsen symptoms during active disease.
Bronchiectasis
Risk factors for bronchiectasis include previous severe or repeated respiratory infections, cystic fibrosis, immune-system problems, inflammatory diseases, and conditions that interfere with airway clearance. Risk may also increase with certain structural lung abnormalities and long-term exposure to irritants. Older age can be associated with increased risk, particularly when other lung or immune conditions are present.
