CONCLUSION:
In conclusion, we presented a case of a 74-year-old man with a history of pulmonary tuberculosis who showed signs of impaired consciousness, lower limb weakness, and severe hyponatremia. Mycobacterium tuberculosis was detected through GeneXpert. Our case indicates the significance of considering pulmonary tuberculosis as a possible cause of electrolyte imbalance. Particularly in regions where tuberculosis is endemic, healthcare professionals should not undervalue the link between pulmonary tuberculosis and electrolyte abnormalities. To avoid potential problems and improve patient outcomes, it is essential to identify and treat dyselectrolytemia in patients with respiratory symptoms. When dealing with electrolyte imbalances in cases presenting with these symptoms, healthcare providers should include tuberculosis in the differential diagnosis.
