Sol.
Explanation:
·
Weight loss is a hallmark symptom of
active tuberculosis (TB), often referred to as
"consumption". This weight loss is due to the body's increased energy expenditure while fighting the infection and the overall effect of chronic illness on metabolism.
·
Increased appetite is typically not associated with TB; in fact, many TB patients experience
reduced appetite due to illness and other symptoms.
·
Dyspnea on exertion (difficulty breathing with activity) can occur in severe cases of TB when lung tissue is extensively damaged. However, it is not as common in the early stages of TB.
·
Mental status changes are not a typical symptom of active tuberculosis unless there is involvement of the
central nervous system, such as in
tuberculous meningitis (which is a more severe and less common form of TB).
