Tuberculosis is an infectious disease caused by the bacillus Mycobacterium tuberculosis. It affects the lymph nodes, intestine, meninges, bones and joints, skin etc.


Pulmonary tuberculosis is accompanied by

  • wasting of tissues
  • exhaustion
  • cough
  • expectoration (cough with respiratory secretions) and
  • fever

The acute phase resembles pneumonia, with high fever and increased circulation and respiration.

The chronic phase is accompanied by low-grade fever. Though the metabolic rate is high, it is lower than in acute fever.


Energy High calorie diet with 2500 to 3000 Kcal. It is not desirable to gain more than 10 per cent above the ideal body weight.

Protein Serum albumin levels are decreased, therefore, 80 to 120 g of protein per day is desirable.


  • The drug isoniazid interferes with vitamin D metabolism.
  • Decreased absorption of calcium and phosphorus. Therefore liberal amount of calcium for healing tuberculosis lesions.
  • Iron as per the level of haemorrhages.
  • Calcium, iron and phosphorus help in regeneration of cells, blood and fluids.


Vitamin A and C requirement increases.

Isoniazid is antimetabolite of pyridoxine and prevents the formation of pyridoxal phosphate. Hence 50 to 100 g of pyridoxine is necessary.


High calorie, high protein, high vitamin, high minerals, high fluid and soft diet is recommended. Along with high calorie, high protein, high vitamin and minerals.
