What makes my blood sugar go up?

In order to understand what makes your blood sugar go up, let’s review what blood sugar is and does. Blood sugar is the fuel we all have and need to function. Blood sugar is simply the amount of sugar in your blood. It is also sometimes called glucose. Blood glucose is simply the level of glucose, or sugar, in your blood. Pretty straightforward. A healthy fasting (i.e. without any food in your system) blood sugar range is between 70–100 mg/dl, and less than 140 mg/dl two hours after meals.

Normally, blood glucose levels are tightly regulated by insulin and several other hormones in the body. When people eat and digest food, blood glucose levels rise as the digested sugar passes into the bloodstream from the intestines. In response to rising blood glucose, the pancreas releases insulin. Insulin lowers blood sugar by moving glucose out of the bloodstream and into the liver, muscle, and fat tissues of the body, where it is used as fuel or stored for the body to use later.

As soon as someone eats after not eating for a while, insulin is quickly released from the pancreas. Insulin is a hormone that your body needs to break down the foods you eat into energy. After a meal, blood sugar levels peak at less than 140 mg/dl and then gradually fall back to the baseline (pre-meal) range. The extra insulin moves glucose from the meal out of the blood stream to be stored for future use or used immediately for fuel for the body.

All that said…blood glucose levels rise for a number of different reasons: food, irregular eating schedules, illness, injury, stress, medication… If your blood sugar levels are too high too often, let your doctor know so that, together, you can figure out what’s causing the high levels and adjust your treatment plan.
