My father is 92 years old, has trouble walking due to sleeping most of the time, and lately his appetite has gone to almost nothing. He sips water, OJ, eats a few spoonfuls of food, but doesn t show any signs of hunger or interest in food. I give him soft foods, his teeth are bad, but I don t think that s it, as he shows no signs of hunger. He is losing weight. Seems like he s just slowly fading away, which wouldn t be unexpected at his age.
