A pregnant person puts a portable container of fast-acting glucose in a bag pocket before going for a walk.
Carrying the recommended source of glucose can make it easier to follow your personal plan if a low occurs while you are out.

A preventive plan, without making changes on your own

If you use insulin during pregnancy, preventing low blood glucose involves anticipating situations and following a plan agreed upon with your health care team. Insulin needs can change during pregnancy, so follow-up should be individualized. Do not reduce or stop your treatment on your own; tell your team if you have an episode so they can discuss next steps with you.

Confirm what to do if things change or symptoms occur

Ask how to follow your prescribed monitoring plan, whom to contact, and what steps to take if symptoms occur or your routine changes. Discuss what to do if you become ill, have less appetite, or cannot eat as usual. If you use more than one diabetes medication, bring an up-to-date list to your appointments. There is no adjustment that is right for everyone.

Coordinate meals and timing

Plan meal and insulin timing according to the instructions you received; the relationship between the two depends on your plan. If a meal is delayed, skipped, or you cannot eat as usual, follow the instructions you were given or contact your team. Avoid improvising changes to your schedule or medication.

Plan physical activity

Physical activity can affect blood glucose. Its effect depends on the type of activity, timing, and treatment. Before changing your routine, ask how to coordinate movement with meals, medication, and the monitoring recommended for you. When going for a walk or doing another activity, carry the fast-acting source of glucose recommended for you and make sure you know the instructions for using it.

Prepare for days that are different from usual

Travel, an appointment, a shift change, reduced appetite, or increased activity can disrupt your usual schedule. When possible, plan how to maintain coordination among meals, activity, and medication. If a change is unexpected and you do not know what to do, contact your care team for individualized guidance.

Carry the recommended source of glucose

Ask which fast-acting source of glucose is appropriate for you, how to carry it, and how to use it according to your plan. Make sure it is available when you go out. If you have discussed this with your care team, tell people close to you where to find it and what instructions to follow. Do not replace those instructions with general guidance.

Recognize symptoms and emergency signs

Low blood glucose can cause shakiness, sweating, sudden hunger, palpitations, dizziness, weakness, or difficulty concentrating; these symptoms alone do not confirm the cause. Follow the instructions in your plan. Tell your team about repeated or severe episodes. If there is a loss of consciousness, seek urgent care. If the person does not respond or cannot follow instructions, call for emergency help and do not give them food or drink by mouth.

Record what happened for follow-up

After an episode, write down the symptoms, timing, and context—for example, whether a meal was delayed or there was a change in activity—along with any information your team has asked you to record. Share this information during follow-up so they can review your plan individually.

When to seek medical care

If symptoms persist, test results are abnormal, or you have questions about medication, arrange an individual assessment. Do not change treatment or doses without medical guidance.

Frequently asked questions

Should I stop insulin if my blood glucose is low?

Do not stop or reduce it on your own. Follow the instructions you received for the episode and inform your care team so they can review the plan with you.

What should I do if a meal is delayed or my activity changes?

Follow the instructions you received for those situations. If you do not have clear instructions, contact your health care team rather than improvising changes to your insulin.

When is urgent care needed?

Tell your team about repeated or severe episodes. If there is a loss of consciousness, seek urgent care; if the person does not respond or cannot follow instructions, do not give them food or drink by mouth.
