From the Guidelines
Shortness of breath (SOB) is not explicitly mentioned as a symptom of TB in the provided evidence, however, it can be inferred that TB may lead to respiratory symptoms that could cause SOB. When considering the morbidity, mortality, and quality of life, it is crucial to evaluate patients with chronic cough, sputum production, hemoptysis, fever, or weight loss for TB, especially in high-risk populations or geographic areas with a high prevalence of TB 1. The evidence suggests that cough is a cardinal feature of tuberculosis, and TB should be considered early in the evaluation of patients with chronic cough when the likelihood of active TB is high 1. While the provided study does not directly link SOB to TB, it emphasizes the importance of considering TB in the diagnosis of patients with respiratory symptoms, particularly in high-risk populations or areas with a high prevalence of TB. Key points to consider in the evaluation of TB include:
- Geographic areas with a high prevalence of TB
- Populations at high risk of TB, such as HIV-seropositive persons
- Symptoms like chronic cough, sputum production, hemoptysis, fever, or weight loss
- The potential for TB to remain latent for many years, only to emerge as clinical infection when patients become immunocompromised.

From the Research
Symptoms of TB
- Shortness of breath (SOB) can be a symptom of various conditions, including tuberculosis (TB) 2
- TB is a bacterial infection that primarily affects the lungs, and its symptoms can include cough, chest pain, and difficulty breathing 3
Diagnosis of TB
- The diagnosis of TB typically involves a combination of clinical evaluation, chest radiography, and laboratory tests such as sputum smear microscopy and culture 3
- Breath tests have also been explored as a potential diagnostic tool for TB, with some studies showing promising results 4
- However, the accuracy of these tests can vary, and further research is needed to fully evaluate their effectiveness 4
Relationship between SOB and TB
- While SOB can be a symptom of TB, it is not a specific or definitive indicator of the disease 2
- A diagnosis of TB requires a comprehensive evaluation and laboratory testing, rather than relying solely on symptoms like SOB 3
- The pathophysiology of dyspnea (SOB) is complex and can involve various factors, including respiratory, cardiac, and neurological components 2
