DKA is more common in people with Type 1 diabetes than Type 2 diabetes, but can still occur in people with Type 2 diabetes. DKA can develop when the body does not have enough insulin. Without enough insulin, the body cannot use glucose for energy, so the body breaks down fats to use for energy. When the body breaks down fats, it makes waste products called ketones. The body tries to eliminate ketones in the urine, but the body cannot get rid of all the ketones, so they build up in the blood, which can lead to DKA. DKA can lead to a diabetic coma or death\u2014it is life-threatening and requires emergency treatment.\u00a0<\/span><\/p>\n<p><a href=\"https:\/\/my.clevelandclinic.org\/health\/diseases\/21147-hyperosmolar-hyperglycemic-syndrome\" target=\"_blank\" rel=\"noopener\"><span style=\"font-weight: 400;\">Hyperosmolar hyperglycemic syndrome<\/span><\/a><span style=\"font-weight: 400;\">, or HHS, is more common in people with Type 2 diabetes who do not have their diabetes under control. It can occur when blood sugar is high over a long time. Normally, the kidneys try to eliminate excess blood sugar in the urine, but this also causes water loss. If you do not drink enough fluids, you become dehydrated. When this happens, the kidneys can no longer eliminate extra sugar in the urine, and blood sugar levels become very high, sometimes more than 10 times the normal number. HHS is a medical emergency and can cause a coma or death if not treated. People who develop HHS often have very high blood sugar levels, around 600 mg\/dl. Along with very high blood sugar, dehydration and decreased alertness or consciousness may occur.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Having high blood sugar over <\/span><a href=\"https:\/\/medlineplus.gov\/ency\/patientinstructions\/000327.htm\" target=\"_blank\" rel=\"noopener\"><span style=\"font-weight: 400;\">long periods of time<\/span><\/a><span style=\"font-weight: 400;\"> can also lead to serious health problems, and long-term complications, such as problems with the eyes, feet, skin, blood pressure, cholesterol, nerves, kidneys, and digestion.

Conditions such as DKA or HHS are life-threatening and can cause coma or death if not treated.

For example, if your target range is 80-130 mg\/dl, your healthcare provider may advise you to inject a certain amount of insulin if your blood sugar is 200 mg\/dl, or check ketones and contact your doctor if your blood sugar is 240 mg\/dl.<\/span><\/p>\n<h3 id=\"what-are-normal-blood-sugar-levels-before-and-after-eating\"><span style=\"font-weight: 400;\">What are normal blood sugar levels before and after eating?<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">For adults with diabetes, a normal range before eating is generally 80-130 mg\/dl.
