I had a major trauma about 4 months ago which resulted in a spell in intensive care and then about a week in an ordinary ward. As one who likes his food I found I wasn't fancying much, mainly due to having a dry mouth. The hospital didn't press me to eat and, when I got home, my wife let me choose the meals and let me eat as much, or little, as I wanted. My appetite soon returned to normal and now the problem is trying not to eat so much that I put on weight. Be patient, life will soon be back to normal.
