Introduction
The association between TB and undernutrition has long been known. TB and
undernutrition interrelate in such a way that TB negatively affects the nutritional
status of somebody and undernutrition exposes someone to active TB.1–3 Most
individuals with active TB are in a consumed state worsening undernutrition and
making them weak in defending against infections or allowing them to sustain

fatigue or may not get enough to eat if they have few resources.4,6 It has also been
