Stress
In most people stress can affect blood glucose levels by causing it to rise. This is normally a result of other hormones released during stress, which stop insulin from acting properly. One common type of stress is an illness, such as flu.
In some people, especially children, the opposite can occur. This may be linked to other hormones or may be due to a disturbance of routine, such as missing meals or increased physical activity.
It is difficult to predict how you will be affected by stress, as stress itself is unpredictable. However, more frequent blood glucose tests will make you aware of what is happening. Treatments may require adjustment or alteration.
Another suggestion is to find a method of relaxation, such as yoga, meditation or massage. Many people find that this helps considerably with their glucose control.
