How can I help my mother deal with nausea from chemotherapy?

Encourage meds! Nausea is horrible! Thanks for helping your mother. Hopefully her doctor gave her several medicines to try. Make sure she tries them all. If she can't keep them down, ask her doctor for suppositories. If the medicines don't work, ask her doctor for others, and encourage your mom to take them even when she feels better. We have such good meds now that no one should have nausea from chemo!
Chemotherapy. Make sure your mother takes the scheduled and as needed medications for nausea prescribed by her doctor. Make sure she drinks lots of fluids. Have her try to eat frequent small amounts rather than 3 big meals.
