What Does It Mean If Blood Sugar Is Low

Possible Causes With Diabetes

Diabetes affects your bodys ability to use insulin. Think of insulin as the key that unlocks your cells, letting in glucose for energy.

If you have diabetes, a variety of treatments can help the cells in your body use the glucose in your blood. Among these are insulin injections and oral medications that increase insulin production.

If you take too much of these types of medications, your blood sugar may drop too low. You may also sometimes experience low blood sugar if you plan to eat a big meal but then do not eat enough.

Skipping meals, eating less than usual, or eating later than usual but taking your medication at your usual time can also lead to low blood sugar levels.

Unplanned excess physical activity without eating enough can also cause a drop in blood sugar levels.

Drinking alcohol when youre on these medications can also lead to low blood sugar, especially if it replaces food. When your body is trying to get rid of alcohol, it becomes worse at managing blood sugar levels.
