What happens if type 2 diabetes is not treated?

High glucose may cause increased thirst, frequent urination, tiredness or unintentional weight loss. Over time, changes in small blood vessels can affect vision and kidney function. Changes in nerves may reduce feeling in the feet, so a blister or cut can go unnoticed and heal slowly. Larger blood-vessel damage can raise the risk of heart and circulation problems. These effects can develop quietly, even when a person feels well, which is why regular checks matter.

Arrange a clinical assessment rather than waiting for symptoms to worsen. A diabetes screening test can help confirm whether glucose is high, while a chronic disease review can check blood pressure, weight, feet, kidney health and treatment needs. Lifestyle support may include a diabetes education programme, nutrition counselling or a weight management programme. Do not stop or change prescribed medicine without medical advice; treatment is adjusted to your results, other conditions and daily routine.

Seek urgent medical help for confusion, severe weakness, repeated vomiting, difficulty breathing, fainting, or marked drowsiness. Prompt assessment is also needed for a new foot wound, spreading redness, sudden vision change, chest pain or one-sided weakness. These symptoms need examination because they can signal a serious glucose or circulation problem.

Ask which glucose checks you need, whether your kidneys, eyes and feet require review, what symptoms should trigger same-day help, and how food, activity and medicines can fit your routine.
