Understanding and Managing Stress
Although many variables can contribute to fluctuations of your INR, stress is often an unforeseen factor. It has the potential to influence lifestyle and can be brought on by a variety of factors:
Environmental: The human body responds to environmental changes such as temperature. Conditions vary across the United States and can result in drastic temperature changes that your body can take time to get used to.
Physical: Stress can be brought on by a variety of physical conditions. Pain can induce stress on the body, which can cause more complications if it is a result of a fall. Colds and flu can increase stress with body changes, fevers, or loss of sleep; which can introduce fatigue, another form of stress.
Emotional: The body also reacts to adverse emotional conditions. Some stress is due to worry and concern, or significant loss. Worry can be caused by various reasons including financial, work related, and changes in INR levels.
People taking warfarin, who are otherwise within therapeutic range, sometimes can experience instability of their INR test results. Stress and any resulting dietary deficiencies may be a possible reason for unexplained INR results, especially if your dose has remained constant, and other medication use has been consistently taken.
