What is the connection between dizziness and blood sugar levels?

Dizziness tends to follow blood sugar levels, typically when they are too high or too low.

Low blood sugar (hypoglycemia): When the blood sugar level drops below a normal level (typically below 70 mg/dL), dizziness, shakiness, confusion, sweating, and fainting are induced. Glucose is what the brain utilizes as its source of energy; therefore, when it has not enough glucose, it acts irrationally and induces the brain to create these symptoms of dizziness, and more.

High blood glucose (hyperglycemia): While dizziness is less common with high blood glucose, dizziness can still occur, especially when blood glucose levels are very elevated. Dehydration (excessive urination) from high blood sugar can be caused by high blood glucose, which causes dizziness. Furthermore, routine high blood sugars can wreak havoc on your circulation and body fluid management, creating the feeling of lightheadedness.

Maintaining blood sugar levels within their normal limits will prevent dizziness and other complications. If you are constantly feeling dizzy, you need to seek advice from a medical professional as it may be a sign of an underlying health issue.
The treatment for dizziness caused by low blood sugar (hypoglycemia) involves immediate action to increase your blood sugar level and prevent further complications. The following is how you should deal with it:

Consume fast-acting carbohydrates: If you’re feeling dizzy due to low blood sugar, quickly eat or drink something that contains fast-acting carbohydrates. These include:

Glucose tablets (about 15 grams of glucose)
Fruit juice (about 4 ounces or 120 mL)
Regular soda (not diet, about 4 ounces)
Hard candies (such as Life Savers, 3–5 pieces)
Honey or syrup (1 tablespoon)
Wait and test blood sugar: Wait for approximately 15 minutes after taking the fast-acting carbohydrate and test your blood sugar again. If it remains low, take another serving of fast-acting carbs.

Have a balanced snack or meal: After your blood sugar has leveled out, it’s necessary to have a snack or meal that contains both carbohydrates and protein to keep your blood sugar stable. For instance:

A piece of whole-grain bread with peanut butter
A small portion of nuts with fruit
Monitor blood sugar levels often: If you are prone to hypoglycemia, it is important to monitor your blood sugar often, especially before or after exercise, or when you are sick. This keeps you in touch with any changes.

Prevent future episodes: Consider adjusting your diet and medication with the guidance of a healthcare provider to prevent low blood sugar episodes. For example, eating smaller, more frequent meals and adjusting insulin doses (if applicable) can help.

If you’re unable to manage the dizziness or your blood sugar continues to be low, it’s important to seek medical attention, as severe hypoglycemia can lead to confusion, seizures, or unconsciousness.
