In today’s fast-paced world, stress has become an inevitable part of life. Whether it’s a high-pressure job, personal challenges, or health issues, stress can affect our bodies in a variety of ways. One area that can go unnoticed is how stress affects our body. blood test results, which can lead to misdiagnosis or the need for further testing. Understanding the connection between stress and blood tests is critical to obtaining accurate results.
We spoke to Dr. Vishu Bhasin, MBBS, DCP, director and consultant pathologist, who explained that stress, both physical and mental, can significantly skew blood test results.
He said: “Cortisolthe primary stress hormoneincreases both during physical exercise and mental stresspotentially affecting adrenal or thyroid function tests.”
In addition, stress can raise glucose levelsThey affect white blood cell counts and alter lipid profiles, making interpretation of results difficult. Recognizing the effects of stress on blood tests helps prevent misinterpretations and unnecessary medical interventions.
Dr. Bhasin further classified stress into two main types: physical and mental. Physical stress Diabetes mellitus is a consequence of factors such as illness, surgery, or strenuous exercise. It can cause significant changes in blood markers, such as an increase in enzymes such as creatine kinase (CK) and lactate dehydrogenase (LDH) after strenuous workouts, or an elevated white blood cell count due to an immune response to infection or inflammation.
“Physical stressors such as dehydration, fasting or even intense physical activity can dramatically influence blood test results,” he added.
On the other hand, mental stress, which arises from psychological problems such as anxiety, depressionor life pressures—has more subtle, long-term effects. Chronic mental stress can lead to elevated inflammatory markers, such as C-reactive protein (CRP), and even hormonal imbalances, particularly in reproductive hormone tests.
Dr Bhasin said: “It is essential to recognise that mental stress can have a long-term impact, which is often reflected in blood tests related to cardiovascular health or hormonal regulation.”
To ensure accurate interpretations of blood test results, Dr. Bhasin recommended providing your healthcare provider with a complete picture of your recent physical and emotional states.
“Discuss any recent physical exertion, illnesses or life changes that may have affected your test results,” she suggested. By recognizing these factors, doctors can provide more accurate medical advice and avoid unnecessary interventions.
