For people with diabetes, blood sugar can spike. Dehydration—less water in your body means your blood sugar is more concentrated. Nose spray—some have chemicals that trigger your liver to make more blood sugar. Gum disease—it's both a complication of diabetes and a blood sugar spiker.
Overweight, obesity, and physical inactivity
Extra weight sometimes causes insulin resistance and is common in people with type 2 diabetes. The location of body fat also makes a difference. Extra belly fat is linked to insulin resistance, type 2 diabetes, and heart and blood vessel disease.
Higher consumption of coffee, whole grains, fruits, and nuts is associated with lower risk of diabetes, whereas regular consumption of refined grains, red and processed meats, and sugar-sweetened beverages including fruits juices is associated with increased risk.
Common diabetes health complications include heart disease, chronic kidney disease, nerve damage, and other problems with feet, oral health, vision, hearing, and mental health. Learn how to prevent or delay these diabetes complications and how to improve overall health.
In general, foods that cause blood sugar level to rise the most are those that are high in carbohydrates, which are quickly converted into energy, such as rice, bread, fruits and sugar. Next are foods high in protein, such as meats, fish eggs, milk and dairy products, and oily foods.
Frequently Asked Questions. Fruits with a high GI ranging between 70 to 100 contain high sugar content. Such fruits include watermelon, ripen banana, pineapple, mango, lychee and dried dates. These fruits can cause blood sugar spikes and must be avoided.
Diabetics clearly should avoid heavy drinking (i.e., more than 10 to 12 drinks per day), because it can cause ketoacidosis and hypertriglyceridemia. Moreover, heavy drinking in a fasting state can cause hypoglycemia and ultimately increase diabetics' risk of death from noncardiovascular causes.
Target blood sugar levels differ for everyone, but generally speaking: if you monitor yourself at home – a normal target is 4-7mmol/l before eating and under 8.5-9mmol/l two hours after a meal.
For most people without diabetes, normal blood sugar levels are: between 4 and to 6 mmol/L before meals. less than 8 mmol/L two hours after eating.
Avoid Dangerous Blood Sugar if You Have Diabetes. Skipping a meal is typically no big deal. But if you're a person with diabetes, skipping meals or a lack of meal structure could result in dangerously low or high blood sugar levels.
If your insulin level falls too low overnight, your blood glucose rises. The reasons for the drop in insulin vary from person to person, but it most commonly occurs when your insulin secretion provide too little basal back up hence the glucose levels shoots up.
As blood sugar levels rise, the pancreas releases more insulin. Eventually the cells in the pancreas that make insulin become damaged and can't make enough insulin to meet the body's needs.
Over time, the high levels of sugar in the blood damage the millions of tiny filtering units within each kidney. This eventually leads to kidney failure. Around 20 to 30 per cent of people with diabetes develop kidney disease (diabetic nephropathy), although not all of these will progress to kidney failure.
Type 1 diabetes is considered worse than type 2 because it is an autoimmune disease, so there isn't a cure. Also, in a 2010 report⁴ from the UK, it's estimated that the life expectancy of people with type 2 diabetes can be reduced by up to 10 years, while type 1 can reduce life expectancy by 20 years or more.
Factors that contribute to developing type 2 diabetes include being overweight, not getting enough exercise, and genetics. Early diagnosis is important to prevent the worst effects of type 2 diabetes. The best way to detect diabetes early is to get regular check-ups and blood tests with a healthcare provider.
Stress doesn't cause diabetes but it can affect your blood sugar levels and how you look after your condition. Having diabetes to manage on top of life's normal ups and downs can itself be a cause of stress.
If you notice that your blood sugar levels are often high, (above 10mmol) you should contact your diabetes healthcare team. They will review your treatment and provide you with advice on how to get your blood sugar levels back within your target range. This advice may include increasing your medication.
