1) Ask what to answer truthfully, and don't answer if you don't ask.
In line with the principle of maximum honesty, truthfully answer every health condition listed by the insurance company, and don't ask or answer. For example, "health notification" asks if you have been hospitalized in the last two years, but does not ask if you have taken drugs, so you don't need to take the initiative to inform. Even if you have taken medicine recently because of a cold, it will not affect underwriting and claim settlement.
In most cases, the "health notice" lists the types and symptoms of diseases. Generally, as long as the diseases are not listed, you can choose "None" and "None of the above". If you are unclear, you can consult customer service for confirmation.
2) The notification shall be subject to the recorded medical record/physical examination report.
It is precisely because of the importance of "health notification" that many people are too cautious when filling in, and always worry that their information is not detailed enough. Follow the above-mentioned limited notification principle, if there is no clear medical history diagnosis such as physical examination or medical records, there is no need to inform.
