Obesity makes asthma particularly difficult to control

From British Thoracic Society Winter Scientific Meeting December 2017 London

Researchers have demonstrated that diet induced obesity leads to the development of airways hyper-reactivity through the interplay of an immunological and metabolic pathway.

Resultant asthma can affect children as well as adults. Unfortunately obesity associated asthma responds poorly to standard asthma medications including steroids and can result in more hospitalisation and a reduced quality of life.

The most effective obesity treatment is probably bariatric surgery to achieve sustained weight loss. In contrast dietary management and drugs are far less effective.
