Type 2 diabetes and pregnancy complications

Pregnancy changes insulin needs and can make glucose levels more difficult to predict. Higher glucose can contribute to problems involving blood pressure, placental function, fetal growth, or delivery planning. Diabetes may also coexist with chronic kidney disease, obesity, or circulation and nerve problems such as Peripheral Arterial Disease and Peripheral Neuropathy. These conditions do not mean a complication will occur; they help the care team decide what monitoring is appropriate.

Low glucose is another concern for people using insulin or certain medicines. Hypoglycaemia may cause shaking, sweating, hunger, dizziness, or confusion. A pregnancy team can review treatment choices, nutrition, glucose targets, kidney health, and fetal wellbeing at appointments.

Arrange pre-pregnancy or early-pregnancy review when possible, and keep antenatal, diabetes, and other specialist appointments connected. Check glucose according to the plan, record low or high readings, and take medicines exactly as prescribed until a clinician changes them. Ask about folic acid, safe activity, meals, home blood-pressure checks, and scans. Do not begin a weight-loss diet or stop medicine without clinical guidance. Foot checks matter, especially if sensation is reduced or a skin problem such as Cellulitis develops.

Seek urgent help for severe headache with visual change, heavy bleeding, severe abdominal pain, fainting, confusion, repeated low glucose symptoms, or breathlessness. Contact your maternity or diabetes team promptly if glucose readings repeatedly miss your agreed range, vomiting prevents food or fluids, swelling appears suddenly, or you notice reduced fetal movement later in pregnancy. Early contact allows the team to check both parent and baby.

Ask how often to check glucose, which medicines are suitable, what to do during vomiting or low readings, and whether kidney, eye, blood-pressure, or fetal-growth monitoring is needed. Clarify who to call outside appointments and how your delivery plan may depend on glucose control and pregnancy findings.
