Hello @jonathanwinters. Cancer can take a toll on the body and mind, not just the disease itself but also the treatments and medications. It’s not unusual for someone going through cancer treatments to lose their appetite or just lose interest in eating. People in treatment may lose their taste buds and also the sense of taste. So food simply has no appeal.

But nutrition is extremely important throughout the journey. I’m sorry to read that someone you care about is not eating due to their cancer. Equally as sorry to hear that there’s an insurance denial for an appetite stimulating drug.
Has the doctor or medical team stepped in to appeal the denial? I had a drug that was intitially denied but my doctor wrote a narrative and actually called the insurance company to demand approval. It worked…hoping you might be able to do the same. Don’t settle for a no answer! Keep pushing.

You mentioned cannabis for appetite stimulant. There is another discussion in the forum from another member who had the same question. Here is a link to this conversation.
Cannabis use to stimulate appetite

Is your loved one going through treatment at this time? Is she nauseated? Has she been given anti-nausea meds? Is she not eating at all?
