Can caffeine affect blood sugar levels?

If you wake up groggy and feel like you need a gallon of coffee to function, don’t worry; we’ve all been there. However, have you ever wondered if caffeine affects your blood sugar levels? In this article, we will explore the relationship between caffeine and blood sugar levels.

What is Caffeine?

Before jumping into the topic at hand, let’s talk about what caffeine even is! Caffeine is a natural stimulant that can be found in various drinks such as coffee or tea. It stimulates the central nervous system and elevates energy levels while reducing fatigue.

Relationship between Caffeine and Blood Sugar

Now that we know what caffeine is let us dive into how it affects our bodies’ blood sugar level. Drinking caffeinated beverages raises cortisol levels in our body which releases glucose from storage sources like liver cells. Glucose then gets released into our bloodstream increasing blood sugar levels However once this occurs insulin secretion does its thing by decreasing elevated blood glucose concentrations down to normal resting rates.


The rise in cortisol level due to consumption of caffeine peaks at around 30 minutes after consumption (or taking supplements), when consequentially more energy begins releasing from fat tissues accelerating metabolism encouraging gluconeogenesis providing ample glycogen for energetic individuals.

While regular coffee drinkers may feel quite alright after consuming higher doses without unpleasant experiences newcomers then young children older folks pregnant women to name a few are more vulnerable to high dosage stimulant attributes
