Low blood sugar, also known as hypoglycemia, occurs when the level of glucose in the blood drops below normal. This can happen for various reasons, including skipping meals, excessive exercise, or taking too much insulin for those with diabetes. Symptoms may include dizziness, sweating, confusion, and weakness. When blood sugar levels fall too low, the body may struggle to function properly. It's important to address low blood sugar quickly by consuming fast-acting carbohydrates, such as fruit juice or glucose tablets. If left untreated, severe hypoglycemia can lead to more serious complications, including loss of consciousness.
