The consumption of coffee is a very old and popular habit. It is possible that it may have an effect on the respiratory system and on the regulation of respiration. Apart from the manifestations of hypersensitivity linked to the handling of green coffee, the consumption of coffee can have different effects. On the one hand it has a beneficial effect on bronchospasm. On the other hand its consumption has been suspected of contributing to the development of chronic airflow obstruction (COPD) and also in the genesis of bronchial cancer, without, however, its responsibility being proven in a clear fashion. In fact, in these two latter pathological circumstances, the causal relationship is probably indirectly linked to the fact that there is a strong positive correlation between the consumption of coffee and of tobacco. Finally the consumption of coffee increases ventilatory frequency in normal subjects and also in the course of COPD, and if taken in large quantities by pregnant women, there is an increased risk of neonatal apnoea in the newborn, by an abrupt cessation in the caffeine level.
