Im not interested in eating

Patient: I was never interested in eating but lately it has gotten worse. I will not actively look or get food. There will be days where I want nothing to do with food and won’t eat. The look,the smell ,the name of the food sound and smell gross. Even just thinking of it makes me sick. I rarely feel hunger and when I do I eat a tiny bit. And when I have the urge to eat something 5 minutes later it sounds gross.
