Several over-the-counter and prescription medications, including some vitamins and supplements, can have an effect on blood sugar. Niacin, or vitamin B3, is often taken to help lower bad cholesterol, but it can also be used to treat a variety of health conditions. However, when taken in high doses, this supplement can cause hyperglycemia by affecting glucose tolerance in the body. Caffeine is another factor that can cause blood sugar to rise.
This is true for coffee, black tea, green tea and energy drinks. Everyone with diabetes reacts differently to food and drink, so it's important to keep track of your own responses. Interestingly, other compounds in coffee may help prevent type 2 diabetes in healthy people. Cinnamon is a spice that can add flavor without adding salt, carbohydrates or calories.
Some studies suggest that it may also help the body to use insulin better and may lower blood sugar in people with type 2 diabetes. However, more research is needed to confirm this and supplements that contain large doses can cause side effects. Therefore, it's best to talk to your doctor before trying cinnamon. The American Diabetes Association (ADA) notes that research has been mixed as to whether the routine use of nutrients such as vitamin D and magnesium can actually improve blood sugar among people with diabetes.
Certain medications can also increase blood sugar. Statins are a type of medication used to lower cholesterol levels. These medications can make the liver resistant to insulin, leading to a rise in blood sugar. Antibiotics and decongestants can also affect blood sugar.
Exercise is another factor that can affect blood sugar. When you work out enough to sweat and increase your heartbeat, your blood sugar level can rise and then fall. The hormone cortisol is released during exercise and it can increase insulin resistance and fat levels in the body, which can lead to an increase in blood sugar. Gymnema sylvestre is a herb that has been studied for its potential to lower fasting blood sugar.
Berberine is another supplement that may help lower fasting blood sugar, although people with type 2 diabetes should consult their doctor before taking it as there is a risk of slight increases in fasting blood sugar. Niacin supplements should also only be taken under the close supervision of a doctor as they can increase blood sugar. In conclusion, there are several medications, supplements and lifestyle factors that can affect blood sugar. People with diabetes should be aware of these factors and monitor their own responses carefully.
