There can be multiple reasons for missing an appointment some common ones include forgetfulness, scheduling conflicts, transportation issues, emergency illness, and lack of awareness about the importance of keeping the appointment. But I mean, life can get busy, and sometimes unexpected things come up and make it difficult for a patient to make it to their scheduled appointments. I think it is best to always communicate with the medical practice if something comes up so they can make adjustments. I tend to forget a lot of things so some of the strategies I use to remind me of my appointments are setting reminders on my phone, using sticky notes, setting alarms on the day of my appointment, using the appointment reminder services that they offer me$,$ and I usually keep a calendar but since I recently moved I usually just stick to reminders on my phone.
