Given the above research findings, it is recommended that drivers with type 1 diabetes with a history of driving mishaps should never drive when their BG is less than 70 mg/dl (3.9 mmol/l). Instead, these drivers are advised to treat hypoglycemia and delay driving until their BG is above 90 mg/dl (5 mmol/l).[48] Such drivers should also learn as much as possible about what causes their hypoglycemia, and use this information to avoid future hypoglycemia while driving.
Keep your immunizations up to date. High blood sugar can weaken your immune system. Get a flu shot every year, and your doctor will likely recommend the pneumonia vaccine, as well. The Centers for Disease Control and Prevention (CDC) also recommends the hepatitis B vaccination if you haven't previously received this vaccine and you're an adult age 19 to 59 with type 1 or type 2 diabetes. The CDC advises vaccination as soon as possible after diagnosis with type 1 or type 2 diabetes. If you are age 60 or older, have diabetes and haven't previously received the vaccine, talk to your doctor about whether it's right for you.
Because many patients with diabetes have two or more comorbidities, they often require multiple medications. The prevalence of medication nonadherence is high among patients with chronic conditions, such as diabetes, and nonadherence is associated with public health issues and higher health care costs. One reason for nonadherence is the cost of medications. Being able to detect cost-related nonadherence is important for health care professionals, because this can lead to strategies to assist patients with problems paying for their medications. Some of these strategies are use of generic drugs or therapeutic alternatives, substituting a prescription drug with an over-the-counter medication, and pill-splitting. Interventions to improve adherence can achieve reductions in diabetes morbidity and mortality, as well as significant cost savings to the health care system.[62] Smartphone apps have been found to improve self-management and health outcomes in people with diabetes through functions such as specific reminder alarms,[63] while working with mental health professionals has also been found to help people with diabetes develop the skills to manage their medications and challenges of self-management effectively.[64]
As of 2015 the guidelines called for an HbA1c of around 7% or a fasting glucose of less than 7.2 mmol/L (130 mg/dL); however these goals may be changed after professional clinical consultation, taking into account particular risks of hypoglycemia and life expectancy.[18][19] Despite guidelines recommending that intensive blood sugar control be based on balancing immediate harms and long-term benefits, many people – for example people with a life expectancy of less than nine years – who will not benefit are over-treated and do not experience clinically meaningful benefits.[20]
