How Eating Sugar at Night Can Cause Sweating
Carbohydrates are a type of macronutrient. They include starches, fiber, and sugar. Carbs are a key source of fuel for your body.
How Your Body Processes Carbs
The amount and types of carbs you eat have a direct influence on your blood sugar level. For example, sources of starchy and fibrous complex carbohydrates, like whole grains, legumes, fruits, and vegetables, provide a slower release of sugar into the bloodstream for sustained energy.
On the other hand, the body quickly digests and absorbs simple carbohydrates, like refined or processed grains, sugar, honey, and candy. This causes your blood sugar to spike quickly. In response, your body produces a lot of insulin to control your blood sugar level.
In turn, your blood sugar level drops rapidly, perhaps to a level that is too low (hypoglycemia), resulting in a sudden drop in energy, or a “sugar crash.” One side effect of hypoglycemia is sweating.
Diabetes Medications Can Cause Low Blood Sugar and Sweating After Eating
This can happen to anyone, but it’s more common in people who are taking medications to treat diabetes.
“Sweating after eating is not considered a sign of diabetes,” says Seogeun Hong, MD, a primary care physician practicing in Orange, California. “However, if a patient who takes diabetes medications has sweating, it can be a sign of hypoglycemia.”
Sweating and feeling hot at night aren’t the only symptoms of hypoglycemia. Other nighttime symptoms include:
- Having nightmares or crying out
- Feeling tired the next morning
- Feeling disoriented when you wake up
- Irritability
