I drew a family tree and left question marks on it

Thyroid problems appear in my family, though I realised I did not know the exact diagnosis for everyone. My cycles were irregular, and search results made the two facts feel connected before anyone had assessed me.

I drew a small family tree. I wrote confirmed conditions where I knew them, “unsure” where I did not, and approximate ages only when relatives had shared them. I did not call people for private medical details they had never offered.

On a separate page I listed my cycle dates, symptoms affecting daily life, medicines, and questions. At the GP appointment I said, “This is the family history I know, and this is my current pattern. I do not know whether they are related.”

That sentence prevented the family tree from becoming a homemade diagnosis. The clinician asked which relatives were affected and explained what information might matter. Some blanks stayed blank.

I had thought good preparation meant arriving with a complete lineage. It turned out to mean marking the quality of the information as honestly as the information itself. Family history can guide a professional question; it cannot make every resemblance causal. My page now contains facts, question marks, and a next step—three different things, all useful.
