Living with diabetes: the things that actually move the needle

A diabetes diagnosis is not the emergency it can feel like, but it does change how you need to look after yourself. The encouraging part is that most of what determines long-term outcomes is within your influence, and it is a shorter list than people expect.

Know your HbA1c, not just your daily sugar

A finger-prick reading tells you about this moment. HbA1c reflects your average blood sugar over roughly three months, and it is what your risk of complications actually tracks. Most people with diabetes should have it checked every three to six months. Ask what your number is, ask what target your doctor is aiming for, and ask whether that target is the right one for you — targets differ with age and other conditions.

The checks that catch complications early

Diabetes complications are far more treatable when found before they cause symptoms. These are the ones worth being disciplined about:

• An eye examination every year — diabetic retinopathy is silent until it is advanced, and treatable when it is not
• Urine microalbumin annually, which detects kidney involvement long before a creatinine rise does
• A foot examination at each review, checking sensation and circulation
• Blood pressure at every visit — controlling it protects your kidneys as much as sugar control does
• A lipid profile annually, since cardiovascular risk is the main long-term concern

Habits, in rough order of impact

• Take your medication consistently. Nothing else on this list compensates for missed doses.
• Walk for about 30 minutes on most days. Regular moderate activity improves insulin sensitivity more reliably than occasional intense exercise.
• Reduce refined carbohydrates and sugary drinks rather than attempting an unsustainably restrictive diet.
• Sleep properly. Short sleep worsens glucose control measurably.
• Stop smoking. In someone with diabetes this is the single largest cardiovascular risk you can remove.

When to contact us sooner

Get in touch promptly if you have repeated very low readings or episodes of shakiness, sweating, and confusion; persistently high readings despite taking your medication; a foot wound, blister, or ulcer that is not healing; sudden visual change; or vomiting and inability to keep fluids down while unwell. Foot wounds in particular should be seen within days, not weeks.

A word on advice from elsewhere

Diabetes attracts more confident misinformation than almost any other condition. Please do not stop or reduce prescribed medication on the strength of something you read or were told, however plausible it sounded. If you want to try something, bring it to your review and discuss it — that conversation is a reasonable one to have, and we would much rather have it than find out later.
