Prediabetes and Summer Weight Gain: What Your Numbers Are Telling You

Most people view seasonal weight gain as a winter issue, something that creeps up through the holidays and peaks in January. But summer has its own ways of packing on pounds, and if you’re already living with prediabetes, those extra pounds can have a big impact on your blood sugar. 

The West Bridgewater and southeastern Massachusetts community can rely on receiving exceptional care here at Bridgewater Primary Care and Cardiology, LLC. We have you covered with a full range of services from preventive care to chronic disease management. 

If you have or are at risk for prediabetes, the good news is that you have time to make meaningful changes to prevent progression to diabetes. 

What is prediabetes, and what do your numbers mean?

More than 115 million Americans have prediabetes, which means their blood sugar runs higher than normal, but not high enough for a diabetes diagnosis. Two numbers matter most: your fasting glucose and your A1C. A fasting glucose between 100 and 125 mg/dL, or an A1C between 5.7% and 6.4%, puts you in prediabetes territory.

Prediabetes is a warning sign and a window of opportunity to make changes that can bring your blood sugar levels back into the normal range, often without medication. While it’s tempting to overhaul your lifestyle with drastic changes, small, practical changes usually prove more sustainable over the long term. 

Why does summer spike blood sugar?

Diet and lifestyle habits often shift during the summer months. People tend to dine out more and eat more desserts like ice cream, which sneak in extra sugar and calories. Vacations disrupt sleep schedules, and irregular sleep raises insulin more than most people expect.

Add longer daylight hours packed with social events, and it becomes easy to get in the habit of grazing all evening without noticing. It happens because summer changes your environment, which in turn has a major impact on your habits.

What numbers should you keep an eye on this summer?

Beyond fasting glucose and A1C, pay attention to your weight and waist circumference. Carrying extra weight around your midsection raises insulin resistance more than weight carried elsewhere. 

If you’re testing at home, watch post-meal readings too. A spike above 140 mg/dL two hours after eating means a particular meal pushed your system harder than it should.

How can you turn your summer habits around?

Focus on making small swaps. Trade one sugary drink a day for sparkling water with fruit. Take a 15-minute walk after dinner, since movement right after eating blunts the blood sugar spike that follows a meal. Protect your sleep, even on vacation, since even a few nights of poor sleep can shift your numbers.

Stick to a regular eating schedule, even in the warmer months. While summer may involve less structure, eating at the same time each day prevents unintentional grazing. Unplanned snacking can easily add excess calories and carbohydrates to your daily intake. 

If you’ve gained weight, following these tips for the summer and beyond can help you reverse course. Weight loss is one of the most powerful ways to boost insulin sensitivity and improve glucose control. Shedding as little as 5% of your body weight helps prevent diabetes: that’s 10 pounds for a 200-pound person.

When should you talk with your provider?

If it’s been more than six months since your last A1C, or if you’ve noticed your weight creeping up this summer, don’t wait until fall to check in. Our team offers in-house lab testing, so you can get prompt answers about where your numbers stand today.
