Blood sugar monitoring in pregnancy: Questions for Your Diabetes Team

Blood glucose monitoring helps your diabetes team see whether treatment is meeting your needs during pregnancy. The most useful plan explains not only how to obtain a number, but when to check, how to record it and what action to take. Ask for a demonstration before relying on unfamiliar equipment.

Make the instructions specific to you

Testing often includes a reading before breakfast and after meals. Some treatment plans need additional checks. Confirm your own schedule, including whether a meal timer starts with the first bite and whether you should test one or two hours later.

Write down the target for each testing time and the units shown on your meter. Numbers from an online discussion may use different units or a different timing, so they are not a substitute for your plan. Our gestational diabetes overview explains how monitoring fits into care.

Practise using and recording the equipment

Wash your hands before a finger prick check and follow the instructions supplied with your meter. Ask the team to watch you do a test if you are unsure about the strip, lancet or sample. Confirm how to obtain replacement supplies before the first pack runs out.

Record the time, result and relevant context, such as a delayed meal or illness. Ask how the team wants you to share readings and how often they review them. If an app does not work, arrange another way to send results instead of assuming that somebody can already see them.

Agree what to do outside the target range

Get clear instructions about when to call, which service to use outside office hours and any dose changes you have been taught to make. Do not invent a correction dose or skip food to make the next reading look better. The insulin guide discusses treatment support.

If you become unwell or have high glucose, seek urgent medical advice. Do not wait for the next scheduled upload. A home reading cannot explain every cause of illness during pregnancy.

Prepare for low glucose if your treatment can cause it

Insulin can cause low blood glucose. Shaking, sweating or confusion can be warning signs. Ask your team to explain treatment and what to carry with you. If symptoms occur, check if possible and follow the immediate treatment instructions rather than waiting for a routine reply.

Severe symptoms, loss of consciousness or inability to swallow safely need emergency help. Someone who cannot swallow safely must not be given food or drink by mouth. Tell a support person where to find your emergency instructions.
