Can you see a pattern in specific food/containing ingredients, eaten before your sugar spike? Some people with type1 diabetes for example, react weird to specific ingredients they are sort of “allergic” to, making their glucose level spike, while for others the same ingredients cause no spike at all. These ingredients don’t even contain that much carbs/sugar that would explain a glucose spike.
