My son has to be admitted to hospital this week as he had a asthma attack. Unrelated to his asthma he is underweight after the acute phase of his illness had passed not one HCP commented on his very obvious low weight. I can't help thinking that if he had been obviously overweight it would of been mentioned as a contributory factor in his ill health. Surely very low weight is also unhealthy, is this more acceptable? (p s I'm working hard to correct his weight)
