Excessive blood sugar spikes are usually followed by rapid blood glucose decline, which can cause false hypoglycemia (low blood sugar) symptoms. The sharp decline from a high blood glucose to a normal level can cause the brain to mistakenly think that there is a crisis, resulting in low blood sugar symptoms, including feeling hungry, tired, dizziness, tingling lips, feeling shaky, moody, or turning pale.
If the blood sugar spike persists for long time, it can lead to serious health problems later in life. Over time, it can cause the blood vessels to harden and narrow, which could lead to a heart attack or stroke. In addition, the spike is associated with an increased risk of long-term diabetes complications, including nerve damage, vision loss, and kidney damage.
For Type 1 diabetes, significant rises in blood sugar after meal has been associated with earlier onset of kidney disease, as well as accelerating the progression of existing retinopathy, an eye condition that can cause vision loss and blindness that is most commonly associated with diabetes.
In people with Type 2 diabetes, post-meal blood sugar spikes have been identified as a risk factor for cardiovascular is dementia.
Post-meal spikes in blood sugar is a health challenge worth of attention.
