Diabetes Decoded: A Calm, Practical Guide to Living Confidently With Type 1 Diabetes - From Diagnosis to Daily Life (Smart Diabetes Living : The Type 1 Diabetes Series)

Revised and Expanded Second Edition 2026.

Newly diagnosed with Type 1 diabetes? Start here.

This clear, practical Type 1 diabetes guide helps replace fear and confusion with knowledge, confidence and a real plan for daily life.

Type 1 diabetes can feel like being handed a second full-time job overnight. Suddenly, you are expected to understand insulin, blood glucose, carb counting, hypos, hypers, CGMs, pumps, food, exercise, sick days, school, work, travel, sleep and constant decision-making.

Diabetes Decoded gives you the calm, plain-English explanation many people wish they had been given at diagnosis.

This revised and expanded second edition is a comprehensive real-world guide for newly diagnosed adults, parents, partners, families and carers. Across 524 pages, it explains diabetes in practical, human language, with guidance from Philip D. Hall, who has lived with Type 1 diabetes for more than 34 years.

Philip writes from decades of managing blood glucose through real life: work, family, exercise, travel, stress, illness, food, technology, sleep, fear, frustration and the mental load of diabetes.

This hardcover edition is designed as a lasting reference for the bookshelf, bedside table, clinic room or family home. It is a book to return to when questions come up, confidence dips, or diabetes starts to feel harder again.
