A pregnant person pauses during a walk and wipes their forehead; their hands show a slight tremor.
Sweating and trembling can accompany low blood glucose, but on their own they do not establish the cause.

Symptoms alone do not confirm a blood glucose problem

Trembling, sweating, thirst, or feeling unwell can have various causes during pregnancy. If you have a blood glucose monitoring plan, follow the instructions you received when symptoms appear. Record the reading and what you felt, if you can do so without delaying necessary care.

Possible signs of low blood glucose

Hypoglycemia may be accompanied by trembling, sweating, sudden hunger, palpitations, weakness, dizziness, or difficulty concentrating. Some people also notice irritability or confusion. Symptoms vary and do not reveal your blood glucose level with certainty: follow your monitoring plan and the instructions you were given for what to do.

Discomfort that may accompany high blood glucose

Intense thirst, more frequent urination, fatigue, or blurred vision can occur with elevated blood glucose, but they can also have other causes. If a reading is outside the range your care team gave you, report it according to the plan you received. Check with your team if you feel unusually unwell, even if you do not have all these symptoms.

Being able to continue your activities does not rule out needing guidance

Contact the team managing your pregnancy and diabetes if episodes recur, you notice new symptoms, or your readings are outside your individual targets. Share your measurements and when the symptoms appeared, if possible. Do not delay urgent care to complete a record.

When to seek urgent care

Severe confusion, fainting, or seizures require urgent help. Get help immediately if the person cannot respond or treat themselves, and follow the emergency instructions your healthcare team has given you. Seek urgent evaluation if you have persistent vomiting, cannot keep fluids down, or are getting worse, especially if your blood glucose is outside the indicated range. In Colombia, go to an emergency department or request emergency assistance; do not drive if you are confused, weak, or feel you might faint.

While you are getting guidance

Follow your individual plan for monitoring and managing blood glucose, as well as the instructions for contacting your healthcare team. If symptoms are severe or getting worse, do not wait for your next appointment. Report any reading outside the indicated range. Targets and recommended actions can vary during pregnancy and from person to person.

Do not change medications on your own

Do not change, stop, or repeat insulin or other medications unless instructed by the team familiar with your pregnancy and treatment. Do not use a dose recommended for someone else, either. If you have questions about a reading or dose, contact your care team according to the instructions you received.

Monitoring information can help guide the next step

If you can, note when symptoms began, any available readings, and the instructions you followed. This information may help your healthcare team, but it does not replace an evaluation. This article is for educational purposes and does not replace your plan for gestational or preexisting diabetes or a medical consultation.

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 wait until my next appointment if I have trembling or sweating?

Not necessarily. Follow the monitoring plan you were given and contact your care team if episodes recur, concern you, or occur with readings outside your individual range. If there is severe confusion, fainting, or a seizure, seek urgent help.

Does intense thirst mean my blood glucose is high?

Not on its own. It can accompany elevated blood glucose, but it can also have other causes. Follow your monitoring plan and contact your healthcare team if it persists, you feel unwell, or you have a reading outside your targets.

Are blood glucose targets the same for everyone who is pregnant?

No. Targets and management plans are individualized. Use the values and instructions your healthcare team gave you; do not adjust medications on your own.

Does this topic resonate with you?

Every case is different. Book a consultation to review your history, test results and goals with a personalized plan.
