High blood sugar - self-care

High blood sugar is also called high blood glucose, or hyperglycemia.

High blood sugar almost always happens in people who have diabetes. High blood sugar occurs when:

• Your body makes too little insulin.
• Your body does not respond to the signal insulin is sending.

Insulin is a hormone that helps the body move glucose (sugar) from the blood into muscle or fat, where it is stored for later use when energy is needed.

Sometimes high blood sugar occurs due to stress from surgery, infection, trauma, or medicines. After the stress is over, blood sugar returns to normal.

Symptoms of High Blood Sugar

Symptoms of high blood sugar can include:

• Being very thirsty or having a dry mouth
• Having blurry vision
• Having dry skin
• Feeling weak or tired
• Needing to urinate a lot, or needing to get up more often than usual at night to urinate

You may have other, more serious symptoms if your blood sugar becomes very high or remains high for a long time. Over time, high blood sugar weakens your immune system and makes it more likely for you to get infections.

What to Think About When Your Blood Sugar is High

High blood sugar can harm you. If your blood sugar is high, you need to know how to bring it down. If you have diabetes, here are some questions to ask yourself when your blood sugar is high:

• Are you eating right?
• Are you eating too much?
• Have you been following your diabetes meal plan?
• Did you have a meal or a snack with a lot of carbohydrates, starches, or simple sugars?

Are you taking your diabetes medicines correctly?

• Has your health care provider changed your medicines?
• If you take insulin, have you been taking the correct dose? Is the insulin expired? Or has it been stored in a hot or cold place?
• Are you afraid of having low blood sugar? Is that causing you to eat too much or take too little insulin or other diabetes medicine?
• Have you injected insulin into a scar or overused area? Have you been rotating sites? Was the injection into a lump or numb spot under the skin?

What else has changed?

• Have you been less active than usual?
• Do you have a fever, cold, flu, or another illness?
