Learning ObjectivesDefine Nutritional Support
describe the Nutritional support for TB patients and its significance.
Nutrition constitutes an important part of TB Treatment. Undernutrition increases the risk of Tuberculosis (TB), and in turn, TB can lead to malnutrition. It has been demonstrated that undernutrition is a risk factor for progression from TB infection to active TB disease, and undernutrition at the time of diagnosis of active TB is a predictor of increased risk of death and TB relapse. There is, as yet, little evidence showing that additional nutrition support improves TB-specific outcomes, but low body mass index, as well as lack of adequate weight gain during TB treatment, are associated with an increased risk of TB relapse and death.
The following table illustrates the effect of undernutrition on outcomes in TB.

The basic recommendations to address the nutritional needs of TB patients are discussed below.
- Conducting an initial nutrition assessment of TB patients with further monitoring
- Providing ongoing counselling for patients on their nutritional status; Diet for TB patients starting treatment should include: cereals (maize, rice, sorghum, millets, etc.), pulses (peas, beans, lentils, etc.), oil, sugar, salt, animal products (canned fish, beef and cheese, dried fish), and dried skimmed milk
- Managing severe acute malnutrition according to national guidelines and WHO recommendations
- Managing moderate undernutrition for TB patients who fail to regain normal Body Mass Index (BMI) after two months of TB treatment or appear to lose weight during TB treatment and evaluating for proper treatment adherence and other comorbidities. If indicated, these patients should be provided with locally available nutrient-rich or fortified supplementary foods.
- Special categories of TB patients, such as:
- Children who are less than 5 years of age should be managed as any other children with moderate undernutrition.
- Pregnant women with active TB and patients with MDR-TB should be provided with locally available nutrient-rich or fortified supplementary foods.
6. Micronutrient supplementation for all pregnant women as well as lactating women with active TB. These women should be provided with iron and folic acid and other vitamin and minerals to complement their maternal micronutrient needs. In situations when calcium intake is low, calcium supplementation is recommended as part of antenatal care.
To achieve the above objectives, the guidelines for nutrition for TB patients are available and a mobile application (N-TB) is available for decision-making on nutritional support for TB patients.
Improving nutritional status at a population level is important for TB prevention which should be part of broader actions on social determinants. All efforts should be made to link TB patients for nutritional support which can be done through the existing public distribution system, local self-government or Non-governmental Organisations (NGOs)or donor agencies or through the corporate sector under Corporate Social Responsibility (CSR).
