Obese are more prone to asthma than those of normal weight.

Findings by the scientists at King’s College London who suggested that a protein contributes to inflammation of the lungs as well as increasing hunger:-

  • Th2 cells – specialised cells belonging to the immune system can inflame the lungs and contribute to the development of asthma.
  • Th2 cells also produce a protein known as PMCH which is known to increase appetite.

In one of the several European and American studies which was published earlier this year, out of 330,000 patients, for every normal weight person with asthma, 1.5 who were overweight or obese.

Although researchers wrote that “These findings may provide a mechanistic link between allergic inflammation, asthma and obesity,” as people with asthma are not always obese, further investigation was needed into possible genetic variations of PMCH.
