NHS Doctor Shares 5 Non-food-related Reasons That Could Spike Your Blood Sugar Levels

Blood sugar spikes are dangerous as it could trigger inflammation, oxidative stress, and damage blood vessel linings. The most dangerous, risk of type 2 diabetes, cardiovascular diseases and cognitive decline. When people think of blood sugar spikes, they think of food, carbohydrates or sugary food items that should be avoided. However, there are other things too that are not food, but could spike your blood sugar.

NHS doctor, Dr Amir Khan, who is a general physician with NHS England, resident doctor on ITV's Lorraine and Good Morning Britain, and host of the No Appointment Necessary podcast on his Instagram channel highlighted five non-food related reasons that could spike your blood sugar.

"Did you know your blood sugar can spike even if you haven't had a single bite to eat?" He starts his video with this disclaimer and goes on to say, "Let me share five surprising things that can raise your blood sugar and why it might not always be a bad thing."

<h2>Five Reasons Beyond Food That Could Spike Your Blood Sugar Levels</h2>

Dr Khan shares that stress triggers a rise in cortisol levels that activates the body's fight-or-flight response. This signals the liver to release stored glucose into the bloodstream to provide a quick boost of energy. This thus leads to a surge of glucose in blood and leads to the rise of blood sugar levels. 

"When you're stressed, your body releases cortisol, the fight or flight hormone that tells your liver to release stored glucose to give you energy. Great if you're running from a tiger, less helpful if you're just stuck in traffic. Remember, chronic stress equals chronic glucose spikes and that is not good for long-term health,” he explains. 

He also highlighted that even a single night of poor sleep could increase insulin resistance, which means glucose stays in the bloodstream for longer duration and could lead to elevated blood sugar levels. He said that chronic sleep deprivation could raise the risk of developing type 2 diabetes even in people who try to maintain otherwise a healthy diet. 

"One bad night, your body becomes more insulin resistant. That means glucose hangs around in the blood for longer and over time, poor sleep can increase your risk of type 2 diabetes, even if you try your best to eat well," he says. 

To many people's shock, he says exercise could temporarily spike blood sugar. "Number three, exercise. Yes, even the good stuff. Certain types of exercises, especially intense or resistance training, can temporarily raise your blood sugars. Why? Well, again, it's your body releasing glucose for fuel, but really importantly, long-term, exercise improves insulin sensitivity, meaning lower blood sugars overall. So, this is not a bad spike,” he explains. 

However, he does point out that it is not a bad thing. He notes that certain forms of physical activity, especially intense or resistance training could prompt the body to release more glucose in bloodstream to fuel the muscles. However, he also points out that regular exercise improves insulin sensitivity over time and helps the body regulate sugar more effectively. 

“When you're fighting off a bug, your immune system has to ramp up, and that comes with a glucose surge. It's your body's way of fueling the immune response. People living with diabetes often notice higher blood sugar levels when they're unwell. That's totally normal and they may have to adjust their medication accordingly,” explains Dr Khan. 

What this means is that when your body is fighting off infection, it releases more glucose in your bloodstream that works as a fuel for your immune system. This is why people with diabetes often notice higher blood sugar when they are unwell. However, he points out that this is body's normal response to combat illness.

"Ladies, this one's for you because it's mainly around your periods or the menopause. In the second half of your menstrual cycle, that's the luteal phase, progesterone levels rise. This can make your cells more insulin resistant, meaning higher blood sugars. And of course, in perimenopause and the menopause, estrogen levels decline, and that comes with insulin sensitivity dropping. So you become more resistant to insulin, leading to more frequent spikes in blood sugar. That's why women in their 40s and 50s may notice weight gain, fatigue, or brain fog which can be linked to blood sugar shifts.”

Dr Khan notes that hormonal fluctuations during different phases of menstrual cycle could also influence blood sugar levels. Higher progesterone during luteal phase could make cells more insulin resistant. When estrogen is declining during perimenopause or menopause, it could further reduce insulin sensitivity.

Dr Khan concludes, “So remember, not all blood sugar spikes are bad. Context matters. But if you're seeing high readings and you're not sure why, it's always worth talking to your doctor and it’s not always about what you're eating.”
