When your blood sugar level is too low, it can lead to a range of symptoms that vary in severity. The body's primary source of energy, glucose, has dropped below its normal threshold, prompting the brain and other organs to adapt by releasing stress hormones like adrenaline.
Dizziness and Lightheadedness: Warning Signs
One of the first signs of low blood sugar is dizziness or lightheadedness. This occurs because the brain's ability to function efficiently is impaired when glucose levels drop below 70 mg/dL. According to a study, individuals with hypoglycemia often report feeling faint or disoriented (Source: American Diabetes Association). If left untreated, this can escalate into more severe symptoms.
Tremors and Shaky Hands
As low blood sugar worsens, the body starts releasing stress hormones that cause tremors in various parts of the body. This is a natural response to help stimulate glucose release from stored sources like glycogen in muscles or liver tissue. However, it can be quite unsettling for those experiencing these symptoms.
Sweating and Cold Sweats
A common symptom associated with low blood sugar is sweating. Whether cold sweats or normal perspiration, this bodily reaction aims to aid the process of glucose release from energy storage sites within cells.
Nausea and Vomiting: A Severe Warning Sign
More severe hypoglycemic episodes can result in nausea and vomiting as an extreme response by the body's defense mechanism. In rare cases, when left untreated, it could be a sign leading to unconsciousness or seizures.
Rapid Heartbeat: Body Trying to Stimulate Glucose Release
A rapid heartbeat is another symptom of hypoglycemia caused due to adrenaline rush stimulating cardiac activity for quick glucose delivery from glycogen reserves stored in muscles and liver. In most cases, the heart rate will increase rapidly as a natural mechanism triggered by falling blood sugar.
Unconsciousness: An Extreme Risk Situation
If left unattended or untreated when your body experiences extremely low levels of blood sugar (below 40 mg/dL), it could lead to unconsciousness due to failure in brain function and glucose delivery.
