Reasons for Blood Sugar Swings

 Reasons for Blood Sugar Swings

 

Upswing: Caffeine

Your blood sugar can rise after you have coffee — even black coffee with no calories — thanks to the caffeine. The same goes for black tea, green tea, and energy drinks. Each person with diabetes reacts to foods and drinks differently, so it’s best to keep track of your own responses. Ironically, other compounds in coffee may help prevent type 2 diabetes in healthy people.

Upswing: Sugar-Free Foods

Many of these will raise your blood sugar levels. Why? They can still have plenty of carbs from starches. Check the total carbohydrates on the label before you dig in. You should also pay attention to sugar alcohols such as sorbitol and xylitol. They add sweetness with fewer carbs than sugar (sucrose), but they may still have enough to boost your levels.

Upswing: Chinese Food

When you dig into a plate of sesame beef or sweet and sour chicken, it isn’t just the white rice that can cause a problem. High-fat foods can make your blood sugar stay up for longer. The same is true for pizza, french fries, and other goodies that have a lot of carbs and fat. Check your blood sugar about 2 hours after you eat to know how a food affects you.

Upswing: A Bad Cold

Your blood sugar rises as your body works to fight off an illness. Drink water and other fluids to stay hydrated. Be aware that some medicines, such as antibiotics and the decongestants that can clear your sinuses, can affect your blood sugar.

Upswing: Job Stress

Overwhelmed or unhappy at work? It takes a toll. When you’re under stress, your body releases hormones that can make your blood sugar rise. It’s more common for people with type 2 diabetes. Learn to relax with deep breathing and exercise. Also, try to change the things that are stressing you out, if that’s possible.

Upswing: Bagels

What’s the difference between eating a slice of white bread and a bagel? Bagels are packed with carbohydrates — more than a slice of bread. They have more calories, too. So if you’re craving one, go for a mini version.

Upswing: Sports Drinks

They’re made to help you replenish fluids quickly, but some of them have as much sugar as soda. Plain water is probably all you need for a moderate workout of less than an hour. A sports drink may be OK for longer, more intense exercise.

Upswing: Dried Fruits

Fruit is a healthy choice, but be aware that dried versions will pack more carbohydrates in a smaller serving size. Just 2 tablespoons of raisins, dried cranberries, or dried cherries have the carbs of a small piece of fruit. Three dates give you 15 grams of them.

Upswing: Steroids and Water Pills

People take corticosteroids, such as prednisone, to treat rashes, arthritis, asthma, and many other conditions. But they can boost your blood sugar, and may even trigger diabetes in some people. Diuretics that help high blood pressure, also called water pills, can do the same. Some antidepressants also raise or lower blood sugar.

Upswing: Cold Medicines

Decongestants that have pseudoephedrine or phenylephrine can raise blood sugar. Cold medicines also sometimes have a little sugar or alcohol in them, so look for products that skip those ingredients. Antihistamines don’t cause a problem with blood sugars. Ask your pharmacist about the possible effects of over-the-counter meds before you buy them

Lower: Household Chores

Cleaning the house or mowing the lawn can have an added bonus for people with diabetes: lower blood sugar. Many of the chores you do every week count as moderate physical activity, with plenty of health perks. Make a point of walking around the grocery aisles or parking farther from the entrance to the store. Small amounts of exercise add up.

Lower: Yogurt

Foods that have healthy bacteria, such as many types of yogurt, are called probiotic. They can improve digestion and also may help you control your blood sugar. Some yogurts have added sugar and fruit, so be careful to count the carbs. Your best choice is plain or light yogurt without extra sugar.

Lower: Vegan Diet

One study found that people with type 2 diabetes who switched to a vegan (or all vegetable-based) diet had better blood sugar control and needed less insulin. A boost in fiber from whole grains and beans might play a role, by slowing down the digestion of carbs.

Promising: Cinnamon

A sprinkle of this spice can add flavor without adding salt, carbs, or calories. Some studies suggest it also can help the body use insulin better and may lower blood sugar in people with type 2 diabetes

Roller Coaster: Alcohol

Alcoholic drinks have plenty of carbs, so at first they’ll raise your blood sugar. But your levels may drop for as long as 12 hours after drinking. It’s best to have your booze with food and to check your blood sugar

Roller Coaster: Heat

You’ll be safer inside with the AC when it’s hot outdoors. Heat makes your blood sugar harder to control. You should test it often and drink plenty of water to avoid dehydration. High temps can affect your medications, glucose meter, and test strips, too. Don’t leave them in a hot car.

What About the Glycemic Index?

Your daily carb total, spread steadily across the day, is one key to good blood sugar control. Some people also use the glycemic index (GI), a rating of how individual foods raise blood sugar levels. Beans and whole-grain breads and cereals have a lower GI than white bread or regular pasta. Juice has a higher GI than whole fruit. Craving a high-GI food? Eat it along with a lower-GI choice to help control your levels.
