What is oral glucose and what does it do?
Oral glucose is a concentrated sugar solution, usually in gel or liquid form, designed to raise blood sugar quickly. It is most often used in emergencies, such as for treating hypoglycaemia (low blood sugar), or as part of a diagnostic test like the oral glucose tolerance test (OGTT). In Nigeria, both uses are common in clinics and hospitals.
- Quickly raises blood sugar levels
- Used in emergency hypoglycaemia
- Essential for oral glucose tolerance test (OGTT)
How much is in oral glucose?
A typical tube of oral glucose gel contains between 15 and 25 grams of glucose. This amount is carefully measured to be effective for emergency use—enough to raise blood sugar without causing excessive spikes. The specific quantity can vary by manufacturer, but 15 grams is the most common standard globally.
- Standard tube: 15–25g glucose
- Check the label for exact amount
How much glucose in an oral glucose tolerance test?
For an adult oral glucose tolerance test (OGTT), the standard dose is 75 grams of glucose dissolved in water, taken after fasting. Children receive a lower dose, usually calculated based on their weight. This amount triggers a measurable blood sugar response, helping diagnose diabetes or prediabetes.
- Adults: 75g glucose
- Children: lower dose by weight

How much oral glucose do you give for hypoglycaemia?
For adults experiencing mild hypoglycaemia, the recommended dose is typically 15 to 20 grams of oral glucose. This is usually one tube of glucose gel. If symptoms persist after 15 minutes, the dose may be repeated. Children require less, based on their weight. Always follow medical advice for dosing.
- Adults: 15–20g (usually 1 tube)
- Recheck sugar after 15 minutes
How much oral glucose can an EMT give?
Emergency medical technicians (EMTs) are trained to administer oral glucose to conscious patients who can swallow safely. In most guidelines, they give 15 to 25 grams—usually a single tube. The dose is repeated only if symptoms and low blood sugar persist. Nigerian EMTs follow local protocols, which may vary slightly.
- One tube (15–25g) usually given
- Repeat only if needed and safe
How much sugar is in a tube of oral glucose?
A single tube of oral glucose gel contains 15 to 25 grams of sugar, all as glucose. This is specifically measured to act fast in emergencies and for use in blood sugar testing. Always check the packaging for the exact amount.
- Tube: 15–25g sugar (glucose)
- Always read the label
Why is oral glucose more effective than other forms?
Oral glucose is absorbed quickly through the digestive tract, raising blood sugar faster than many foods or drinks. It is more effective than some other sugars because glucose does not need to be broken down further. While IV glucose is faster in emergencies, oral glucose is safer and easier to administer outside a hospital setting.
- Rapidly absorbed
- No digestion needed
- Safer than IV outside hospital
When should you NOT use oral glucose?
Oral glucose should not be given to anyone who is unconscious, cannot swallow, or is at risk of choking. In such cases, intravenous glucose is safer. People with certain digestive conditions may need alternative treatments. Always consult your healthcare provider before administering oral glucose in uncertain situations.
- Do not use if unconscious
- Avoid if can't swallow safely
