Just as the patient needs to educate himself about his disease, the caregiver too, needs to be well informed. Very often, you may be participating in the diet and treatment implementation. If you are ignorant about these, you may end up making serious errors.
Sometimes, acts of omission are as decisive, as preventive or corrective measures.
Encourage your patient to learn more with you. Ask questions, read books, visit web-sites. Do everything that is within your means, to be prepared for whatever your patient's disease entails
