It's not that unusual for a 20-something to text Mom from the doctor's office for help answering a health question. Or for patients of any age to struggle at recalling all their medicines. Getting the most out of a doctor's visit requires some advance preparation, whether it's a routine checkup or following up on health problems. Ask relatives about diseases that run in the family. Write down the names of prescribed and over-the-counter drugs and supplements you use. And bring a list of symptoms and questions to show at the beginning of the visit so nothing gets forgotten.
