Things Not to Eat If You're Hypo- or Hyperglycemic

Both hypoglycemia and hyperglycemia relate to blood sugar and diabetes. Hypoglycemia, or low blood sugar, occurs when you have excessive glucose in your bloodstream. Hypoglycemia can occur in both diabetics and non-diabetics. You can control hypoglycemia with a proper diet. Hyperglycemia, or high blood sugar, occurs when your blood sugar levels are too high. Diabetes or unhealthy eating can cause hyperglycemia. You can prevent hyperglycemia with proper insulin control and a healthy diet.


Hypoglycemia occurs when your blood sugar becomes dangerously low. When you consume carbohydrates, whether they are in the form of bread or a piece of candy, your body absorbs the sugars as glucose in the bloodstream. Your pancreas then releases insulin into your bloodstream. This insulin converts the glucose into expendable energy, which is expended through metabolic function, exercise or internal processes. If your body releases too much insulin, and too much blood sugar is converted too rapidly, you can experience hypoglycemia.

Glycemic Index

All carbohydrates are processed in the bloodstream as glucose. How quickly a food is processed and converted into energy determines the effect it will have on your blood sugar and hypoglycemia. The glycemic index can help you determine which foods to avoid. Carbohydrates are assigned a number on the index relative to their glucose content compared to pure glucose. High-glycemic foods, such as candy, white bread and dates, have a greater effect on your blood sugar levels, as they will cause a spike, then crash, in your blood sugar levels. Avoid high-glycemic foods to manage your hypoglycemia.


Hyperglycemia, or high blood sugar, can occur in diabetics who cannot naturally control the insulin in their bodies. When insulin converts the glucose in your body into energy, it is preventing your blood sugar levels from becoming dangerously high. If your insulin secretion is not managed naturally or through medication, you can experience hyperglycemia, as glucose builds up in your bloodstream. This condition can be potentially dangerous if left untreated.

Hyperglycemia Prevention

Improper diet or exercise choices, not taking appropriate amounts of glucose medication, or illness can cause hyperglycemia. Proper diabetes management is the key to preventing hyperglycemia. Avoid high-glycemic carbohydrates such as starches or sugary foods. Eating excessive carbohydrates, especially without administering the necessary amount of insulin to lower blood sugar levels, can lead to hyperglycemia. High-fat foods such as fried foods or fatty meats may contribute to insulin imbalances through obesity. You should avoid these foods to prevent hyperglycemia.
