To keep your blood sugar level within this range, eat a healthy, balanced diet and eat meals and snacks on a consistent schedule. This blood sugar chart shows normal blood glucose levels before and after meals and the recommended HbA1c levels for people with and without diabetes. A meal with lots of carbohydrates (for example, cereal and waffles) will increase blood sugar faster than a meal that contains carbohydrates, proteins, and fats (for example, a hamburger and French fries). Blood sugar that stays low for a longer period of time can cause serious complications, such as a coma or seizures.
People who take insulin may have low blood sugar levels if they take too much insulin or if they miscalculate the insulin dose in relation to food, or if they exercise more than usual when there is “fast-acting” insulin on board (in the body). If your blood sugar level is low, you may start to feel some of the first signs of hypoglycemia, such as dizziness, lightheadedness, or sweating.
Blood glucose levelsthat fall outside the ranges mentioned above are classified as high or low blood sugar levels. Talk to a doctor about the amount of insulin you should take if your blood sugar level is above a certain level.
The following table outlines the recommended blood sugar range for people who are pregnant and have type 1 diabetes. People with type 1 diabetes must inject insulin or use it through a pump to control blood sugar levels. Blood sugar levels rise after eating a meal because the body breaks down carbohydrates into glucose, which is then distributed throughout the bloodstream. For people with type 2 diabetes, diet, exercise, and oral medications are used to control blood sugar.
A fasting blood sugar level indicates what your blood sugar level is when you haven't eaten for at least 8 hours. This lab test measures the average level of sugar (glucose) in your blood for the past two to three months. It's important for people with diabetes to talk to their healthcare provider about their blood sugar goals. Blood glucose levels are the amount of glucose, or sugar, that a person has in their blood at any given time.
The purpose of performing a fasting blood sugar test is to determine how much glucose (sugar) is in the blood, and this test is commonly used to detect diabetes or prediabetes.
