Well being

The materials, designs and replacement schedules that contact lenses come in, what each is good for, and why the fitting matters more than the prescription.

Diabetes distress and burnout as named and common experiences rather than character failings, the raised rates of depression and anxiety, fear of hypoglycaemia, eating problems in type 1 — and the psychological support that UK care is supposed to provide every year and most often does not.

Where online supply is allowed and where it is not, what a prescription does and does not contain, why pupillary distance matters, and which prescriptions are a poor bet to order unseen.

Lens materials, index and coatings; the options for reading and distance in one pair; what tints, photochromics and polarisation each actually do; and the frame material question that is a health matter rather than a style one.

Why screens tire the eyes, what actually helps, why most people do not need special glasses for it, and the eye test an employer has to pay for.

What exercise does to glucose and the delayed hypoglycaemia that older advice never mentions, how much activity UK guidance asks for, why there is no such thing as a diabetic diet, and the honest limits of weight loss as treatment.

Whether a child is ready for contact lenses, what the evidence says about infection risk in children, and how myopia management works — the reason lenses are now offered to children who would once have been given glasses and left to it.

Insulin in type 1 and why nothing substitutes for it; the type 2 sequence from metformin onwards, including the shift to using SGLT2 inhibitors for heart and kidney protection; how gestational diabetes is treated; and the treatments that were withdrawn or never existed.

Fear of the dentist runs from mild dislike to a phobia that makes it impossible to pick up the phone.

Difficulty falling asleep, staying asleep or waking too early, with the days affected by it. Why short-lived and chronic insomnia are different problems, why spending longer in bed makes it worse, what cognitive behavioural therapy for insomnia actually consists of, and the narrow and specific place sleeping tablets have in UK practice.

An urge to move the legs that comes on at rest and is relieved by moving, and the repetitive jerks that often accompany it in sleep. Why low iron is the first thing to look for, which common medicines make it worse, and why the drugs that work best at first are no longer the ones given first.
