We often think of diabetes management as something that begins and ends with food and medicine. However, did you know that your mind plays a bigger role than you realise?Stress doesn't just make us feel anxious or overwhelmed; it triggers real, physical changes inside the body that can directly affect blood sugar levels. For people with diabetes, this connection between the mind and body becomes even more crucial, as emotional strain can quietly undo all the hard work of diet, exercise, and medication.

We spoke to Dr Jatin Kumar Majhi, Associate Consultant - Endocrinology, Manipal Hospital, Bhubaneshwar, who explained the mind-body connection in diabetes.

"Stress is more than just feeling tense or overworked. It triggers actual physical reactions in the body. These changes can directly affect blood sugar levels, especially in people with diabetes or other health conditions," said Dr Majhi.

The body may react to stress, whether this stress is psychological, as seen in the case of work, or actual, as seen with an illness or injury, by stimulating the 'fight-or-flight response,' which will then release a series of hormones, including adrenaline or cortisol.

How Stress Raises Blood Sugar Levels

"The stress hormones released during this response tell the liver to release stored glucose into the bloodstream, providing instant energy. At the same time, these hormones make the body less sensitive to insulin, meaning the cells absorb less sugar than usual," explained Dr Majhi.

As a result, blood sugar levels can rise unpredictably, especially in people with diabetes. Over time, this can make blood sugar control more challenging.

"Stress, both directly and indirectly, impacts behaviour, as stress could potentially lead to a person missing their medication, indulging in 'comfort foods' which are high in sugar, reduced physical activities, or poor sleeping habits, all of which will continue to disrupt blood sugar levels."

The link between emotional health and physical health is strong. Psychological or emotional distress doesn't just affect the mind; it alters hormone patterns and daily behaviour, both of which can raise blood sugar levels.

"When an individual experiences psychological or emotional distress, hormonal changes and behavioural shifts result in higher blood sugar levels due to stress impacting hormone regulation," said Dr Majhi.

This makes it essential for people with diabetes to pay attention not only to diet and medication but also to their mental and emotional well-being.

How to Manage Stress Effectively

Stress management is not independent of diabetes management. Both go together, and neglecting one will have an impact on the other. Dr Majhi suggests a few simple tips to manage stress better:

• Practice deep breathing or exercises that help relax the mind.
• Try mindfulness or meditation to become more present and not feel overwhelmed.
• Perform low-intensity exercises such as yoga or walking to release endorphins.
• Get sufficient rest, and practice good sleeping habits.
• Engage in hobbies or other enjoyable activities to improve your mood and reset mentally.

Bottomline

"Stress may be invisible, but its effects on blood sugar are very real. For people with diabetes, managing stress is as important as managing diet or medication. Taking care of your mental health helps keep your blood sugar and your overall well-being," concluded Dr Majhi.
