One hour after eating — reference ranges
The usual moment of the peak: glucose tops out roughly 45-75 minutes after a meal, then falls. There is no universal diagnostic threshold at one hour.
| Band | mmol/L | mg/dL | Was es bedeutet |
|---|---|---|---|
| Typical peak | under 7.8 | under 140 | In most people without diabetes, glucose stays below 7.8 mmol/L even at the peak. |
| Higher peaks | 7.8-11.0 | 140-199 | Common after very large or sugary meals; repeatedly high one-hour values with a slow fall are a pattern worth checking. |
| Very high peaks | above 11.1 | above 200 | A single random value of 11.1 mmol/L or higher with symptoms of diabetes is itself a diagnostic finding. |
Im Kontext lesen
One hour is a trend number, not a diagnosis: meal size, meal composition, exercise before eating and the speed of eating all move it, and the official criteria use fasting, two-hour and HbA1c values instead. What matters at one hour is the shape — how high it goes and how fast it comes back.
Meals that spike high at one hour and crash at two-to-three (the "roller coaster") are the pattern people notice as energy slumps, cravings and early hunger. Protein, fibre and fat in the meal flatten the same curve without changing the total calories.
Wann zum Kliniker
- Values repeatedly above 11.1 mmol/L after ordinary meals — see a clinician.
- Spikes followed by hypo-like symptoms (sweating, shaking, sudden hunger) — the pair is worth investigating.
Nur Referenz, keine Diagnose. Die Schwellen auf dieser Seite sind populationsbezogene WHO- und ADA-Werte; Ihr Kliniker interpretiert Ihre eigenen Zahlen gegen Vorgeschichte, Medikamente und andere Tests. Wenn ein Wert mit Symptomen kommt oder sich weiter in die falsche Richtung bewegt, ist das das Signal zum Handeln — nicht diese Seite.
