Which of the following is NOT a symptom of tuberculosis?

Elevated blood pressure is not recognized as a symptom of tuberculosis. Tuberculosis primarily affects the lungs and is characterized by respiratory symptoms. Coughing up blood, a persistent cough lasting for three weeks or longer, and weight loss accompanied by a lack of appetite are all direct manifestations of the disease. These symptoms occur due to the infection causing damage to lung tissue and affecting overall health, which aligns with the typical clinical presentation of tuberculosis. In contrast, elevated blood pressure is not associated with tuberculosis and is more commonly associated with other health conditions, such as hypertension or cardiovascular problems. This distinction helps in understanding the specific symptoms linked to tuberculosis and differentiating them from those that may arise from other medical issues.
