Diabetes and the Long Game

A new diagnosis of diabetes is not, for most patients, a medical event. It is a biographical one. Something shifts in the way they think about food, about their parents, about the next twenty years. The work of the first consultation is as much to meet that shift as it is to prescribe a drug.

Numbers that matter, and numbers that do not

HbA1c is a useful number; fasting sugar taken at a laboratory three days after a wedding is not. Part of our job is to help patients understand which number is the signal and which is the noise. A single high reading on an ordinary day means less than the average of the last three months. Conversely, a perfectly normal reading after a fasting morning tells us nothing about what happens after dinner.

The quiet complications

What we fear in diabetes is rarely the blood sugar itself. It is the slow, patient erosion — of kidneys, of retinas, of the small vessels of the feet. Annual review of these is not a formality. It is the actual practice of diabetes care, and the part most often neglected in busy clinics.

What usually works

Most patients can, with reasonable effort, reach a reasonable HbA1c with a familiar short list: a walk most days, a few changes in the evening meal, metformin unless contraindicated, and an honest conversation every three months. Newer drugs — the GLP-1 agonists, the SGLT2 inhibitors — have earned a real place, and for the right patient they change the story. But the foundation is ordinary, and that is its strength.

A word on the spouse

No other illness is so clearly a household matter. Whoever cooks, whoever walks, whoever notices the morning hypoglycaemia — they are, in practice, co-authors of the treatment plan. The consultation that excludes them is usually the consultation that fails.
