I started to track my health more closely in my early 30s when I developed a condition called
hyperthyroidism. I had to take a prescription to control my overactive thyroid as I began losing weight and hair seemingly inexplicably. I was also extremely anxious at times for no apparent reason. Prior to this, I didn't have any sort of long-term health issue. Over a period of a couple years, I monitored my weight, free T4 level, and Tapazole dosage. Fortunately, taking the prescription got my thyroid under control and now I don't have to take any prescriptions.
But I learned that it was necessary to not rely on my doctor's records to analyze how I was doing, whether I was improving or not. Also it was important to store my own records in an electronic form for ease of analysis (in this case, a simple spreadsheet).
After our premature son was born, he had a number of issues that required more doctor appointments and home care than the typical child, if there is such a thing as a "typical child". While we should be fortunate he didn't have anything of a serious nature, in my opinion, it became clear that it was necessary to make a log of his health and progress over time. Being new parents, sometimes there were disputes about what happened when and whether
X was "normal" or not. With a log, I could refer to it and say,
X happened on these dates and it has little correlation with
Y. Another benefit of a log for our child is I can see his motor skills or language development, for example, over time when curious in the future.
Finally, my dad's health has been noticeably deteriorating over nearly 10 years. But the downward slide was gradual so it wasn't obvious to me to track anything until last summer when my dad had two serious incidents over the span of a month. When numerous doctors asked my dad and I questions about his medical history, obviously I had to keep careful records of my dad's medical history as I couldn't rely on him or his family doctor.
Probably as a senior and as a man, and simply as someone with a sense of pride and self-dignity, my dad is very reluctant to talk about his health, even to his family members. Thus it was up to me to track my dad's medical history as I recalled it over the past 10 odd years, his prescriptions, symptoms, etc. And 80% of the questions asked by health practitioners were the same, so this effort was well spent to say the least. The flip-side is that by making careful notes of my dad's medical history, we (my dad and I) could bring to the health professionals' attention anything they might have missed in their direct questioning.
Only recently, I learned of a practice called the
Quantified Self. Monitoring everything possibly all the time is a logical progression and with consumer electronics available at an affordable price, I may look into it more. The idea is not much different to having a human coach, personal trainer, or mentor but at a more intimate level than ever before.
