For decades, long hours at a desk or in front of a screen were seen as harmless, just part of modern life. But for people with diabetes, sitting for extended periods is wreaking havoc on blood sugar, metabolism, and hormones. However, with regular physical movement, everyday, you can prevent many health issues.
Muscles are meant to move. Dr Shehla Shaikh, Consultant Endocrinologist at Saifee Hospital, Mumbai, says, “When you sit for long stretches, your body uses less glucose, insulin sensitivity drops, and Type 2 diabetes risks escalate. Even with medication, blood sugar control becomes harder.”
Apart from glucose, prolonged sitting slows metabolism, encourages weight gain, and puts the heart under strain. “People with diabetes are already more vulnerable to cardiovascular complications, and inactivity only compounds the danger.” Dr Shaikh tells, adding, “Hormones, fertility, and sleep cycles are affected too, making prolonged sitting a silent but serious enemy.”
Dr Shaikh further shares ways how sitting worsens diabetes and what to do about it:
Increases insulin resistance: Inactive muscles use less glucose, reducing the body’s response to insulin. This makes blood sugar management tougher.
Slows metabolism: Calorie burn drops, digestion slows, and excess glucose accumulates, promoting weight gain and insulin resistance.
Raises heart risk: Sitting more than eight hours a day can increase cardiovascular risk by almost 30%, affecting blood pressure, cholesterol, and vascular health.
Triggers hormonal and fertility issues: Insulin resistance and obesity disrupt hormone balance, men may see lower testosterone and erectile problems, women can experience ovulation issues and higher miscarriage risk.
Affects sleep and glucose regulation: Excessive screen time before bed suppresses melatonin, lowers sleep quality, and raises night-time glucose levels.
Leads to musculoskeletal problems: Back pain, neck stiffness, and poor posture limit movement, further reducing glucose control.
Here are simple ways to counteract the effects:
- Move every hour—stand, stretch, or take a few steps.
- Walk during calls or meetings to keep muscles active.
- Try small exercises at your desk—shoulder rolls, leg lifts, or calf raises.
- Track sitting time with reminders or fitness apps.
- Reduce screen exposure before bed using night mode or blue-light filters.
Sitting for long periods may worsen diabetes, but small, conscious changes can make a huge difference. “You don’t need a gym to protect your metabolism or improve blood sugar control,” adds Dr Shaikh. “Stand, stretch, and move regularly, your heart, hormones, and glucose levels will thank you.”
