If it has deteriorated during the treatment, you should consult the customer and analyze it carefully. If he is willing to insist, he will insist (respect the patient's choice, although it costs a lot of money, it will not make the patient unwilling). If the patient chooses to give up, let him enjoy, eat and drink during this time, don't avoid eating, try to satisfy him and make him calm and have no regrets. It depends on the patient, not you. If the patient is highly conscious, this matter will naturally be solved with the best of both worlds.
