An adult checks a blood glucose meter reading after measuring their glucose at home during corticosteroid treatment.
A measurement taken during treatment can provide information to discuss follow-up; its interpretation depends on the clinical context.

Before Starting: Corticosteroids Can Raise Blood Glucose

Some corticosteroids can raise blood glucose. The effect varies from person to person and may depend on the type of medication, dose, duration of treatment, and other aspects of your health. Taking them does not mean you will necessarily develop diabetes.

Share Your Medical History and Clarify the Treatment Plan

Before starting treatment, tell the person prescribing the corticosteroid if you have diabetes, prediabetes, a history of gestational diabetes, or have previously been found to have high blood glucose. You can also mention family history and other relevant health information. Ask how long you are expected to take the medication and whether the plan might change. This information helps your healthcare team decide whether blood glucose monitoring is appropriate.

Agree on Whether You Need to Measure Your Blood Glucose

There is no monitoring frequency that is right for everyone. Your healthcare team may consider measurements based on your medical history, treatment, and how your health changes. If you already have a blood glucose monitoring plan, confirm whether it needs to be adjusted while you take the corticosteroid. If a professional other than the person who usually oversees your glucose control prescribes it, inform both professionals.

Report Symptoms That Develop During Treatment

Unusual thirst, needing to urinate more often, blurred vision, or fatigue can occur with high blood glucose, but they can also have other causes. If they occur, contact your healthcare team promptly and describe when they started. If symptoms are severe, worsen, or occur with vomiting, drowsiness, or confusion, seek urgent medical care.

One High Reading Does Not, by Itself, Confirm Diabetes

An elevated result during treatment needs to be interpreted in context. Your healthcare professional considers the type of measurement, your clinical situation, and, when appropriate, other tests or follow-up measurements. For some people, the increase may be temporary; for others, it may prompt further evaluation. A diagnosis is not established from a single isolated reading.

Do Not Change the Corticosteroid on Your Own

If you are concerned about your blood glucose or a reading is high, contact your healthcare team to agree on next steps. Do not stop, reduce, or change the corticosteroid without medical guidance, and do not start medication to lower your blood glucose on your own.

Make Clear Who Will Review the Results

A plan may specify who orders or reviews measurements, how to share the results, and whom to contact if symptoms occur. If different professionals oversee your corticosteroid treatment and blood glucose monitoring, coordinate with them about how to share information. This guide does not replace an individual evaluation.

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

If my blood glucose rises while I’m taking corticosteroids, does that mean I have diabetes?

Not necessarily. An increase during treatment does not, by itself, confirm a diagnosis. Your healthcare team interprets the result along with your medical history and decides whether additional measurements or follow-up are needed.

Does everyone taking corticosteroids need blood glucose monitoring?

There is no recommendation that applies equally to everyone. Whether measurements are needed, and how often, depends on the treatment, medical history, and assessment by your healthcare team.

What should I do if I’m very thirsty or urinating more during treatment?

Contact your healthcare team promptly and describe when the symptoms began and which corticosteroid you are taking. If they are severe or occur with vomiting, drowsiness, or confusion, seek urgent medical care. Do not stop or change the corticosteroid on your own.
