How to Prevent Hypoglycemia Symptoms

Hypoglycemia, or 'low blood sugar,' occurs when the glucose level in the blood falls below normal levels. Glucose is a crucial energy source for the body. When blood sugar levels drop too low, the cells and brain do not receive the necessary energy to function properly. Hypoglycemia can be caused by diabetes or reactions to food (or even not eating enough). It typically results in a rapid drop in blood sugar levels. The condition can be quickly treated by consuming a small amount of glucose-rich food. However, if left untreated, hypoglycemia can lead to confusion, headaches, fainting, and in severe cases, seizures, coma, or even death.

Follow your doctor's instructions. It's essential to follow your doctor's guidance on medication dosage and timing, including insulin and other diabetes medications. Additionally, if your doctor recommends a strict diet or you’ve consulted with a nutritionist, it's important to adhere to the diet plan — one that is designed specifically to avoid hypoglycemia complications and maintain stable blood sugar levels throughout the day.

• Sometimes, the best prevention method is simply to follow the rules and recommendations provided by your doctor.

Regularly check your blood sugar levels. People with diabetes should check their blood sugar at least once a day, ideally first thing in the morning and before meals. It’s important to record the readings, noting the date, time, and results. For diabetics, especially those with Type 1 diabetes, blood sugar levels can fluctuate significantly, so checking frequently is necessary — up to four times a day (before breakfast, lunch, dinner, and before bed). To monitor your blood sugar using a glucose meter, you’ll need to buy a meter, lancets for finger pricks, compatible test strips, and alcohol swabs to disinfect your fingers before pricking. Steps for testing blood sugar levels include:

• Wash your hands with soap and water.
• Use an alcohol swab to clean your index or middle finger.
• Place the lancet on your finger at a 90-degree angle and gently push to prick your finger.
• Squeeze a drop of blood onto the test strip.
• Insert the test strip into the glucose meter and wait for the result.
• Record the reading. A blood sugar level of 70 mg/dL or lower is considered low and is often when symptoms of hypoglycemia begin to appear.

Eat 3 main meals and 3 snacks each day. It’s important to have three main meals and three snacks throughout the day to ensure regularity. Meals should be spaced evenly, and skipping a snack or eating it later than usual can lead to hypoglycemia.

• Arrange meals so that they are no more than 4-5 hours apart.
• Never skip a meal, especially if you have diabetes. This is crucial if you're on diabetes medication.
• Ensure you’re consuming enough calories. For instance, if you’re engaging in physically demanding activities, you’ll need to eat more than usual.

Follow a balanced diet. Your main meals should include high-protein foods such as chicken, fish, or beef, around 90-120 grams. If you're vegetarian, substitute with protein from other sources like eggs, tofu, soybeans, or Greek yogurt. In addition to protein, meals should contain complex carbohydrates and a variety of fruits and vegetables.

• Complex carbohydrates should make up 40-60% of your daily intake, sourced from brown rice, beans, whole wheat bread, and vegetables like kale, cabbage, and broccoli. Limit refined carbohydrates such as white bread, pastries, syrups, and candy.
• Good fruit options include oranges, peaches, grapes, blueberries, strawberries, watermelon, and others; these fruits help balance your meal and provide valuable plant nutrients. Fresh fruit, rich in natural sugars, can help raise blood sugar levels and prevent hypoglycemia.
• The key principle is that your plate should be made up of 2/3 vegetables.

Limit caffeine consumption. Avoid beverages and foods that are high in caffeine, such as coffee, tea, and many sodas. Caffeine can trigger symptoms similar to hypoglycemia, making you feel more fatigued.

Always carry a snack with you. If you are at risk of hypoglycemia, you should always have a snack on hand. Convenient and healthy snacks include string cheese, nuts, yogurt, fruit, and smoothies.

Eat food when consuming alcoholic beverages. Drinking alcohol, especially on an empty stomach, can cause hypoglycemia in some individuals. In some cases, this reaction can be delayed by 1-2 days and may be difficult to identify. Therefore, it's recommended to eat food alongside alcoholic drinks.

Exercise at the right time. Physical activity is highly beneficial for people with diabetes as it helps lower blood glucose levels. However, exercise can also cause glucose levels to drop too low — even up to 24 hours after working out. If you exercise, it's best to wait 30 minutes to an hour after eating. Always check your blood glucose levels before and after exercising.

• Bring a snack if you are doing vigorous exercise, such as running or cycling. A snack can help prevent hypoglycemia.
• Adjust your medication or add a snack if you’re burning a lot of calories. This adjustment depends on your blood glucose test results and exercise intensity. Always consult your doctor if you’re a diabetic and wish to maintain your exercise routine while managing the condition.

Treat hypoglycemia symptoms. If you experience the first signs of hypoglycemia, immediately consume a quick snack. Eat whatever is available as quickly as possible. Symptoms should subside within 10-15 minutes after eating; recheck your blood glucose level after 15 minutes to ensure it has risen to 70 mg/dL or higher. If it’s still too low, eat more. There's no need to visit the hospital or see a doctor at the first sign of hypoglycemia. If possible, sit down to avoid fainting. Quick snack options include:

• 120 ml of fruit juice (orange, apple, grape, etc.)
• 120 ml regular soda (not diet soda)
• 240 ml milk
• 5-6 pieces of candy
• 1 tablespoon of honey or sugar
• 3-4 glucose tablets or 15g glucose gel. Note: The appropriate dosage for children may be lower; read the instructions carefully to determine the proper dosage before giving glucose medication to a child.

Understand how hypoglycemia occurs. Hypoglycemia, or low blood sugar, happens when blood sugar levels drop below normal. Symptoms of hypoglycemia usually occur when blood sugar is below 70 mg/dL. Hypoglycemia primarily occurs in people with diabetes due to reactions from insulin treatment, inadequate calorie intake, insulin overdose, or excessive energy expenditure without enough calorie replacement (for example, long-distance running without a snack).

• Rare causes include tumors in the pancreas that result in excess insulin production (insulinoma) and reactive hypoglycemia (which occurs when blood sugar drops after eating a specific food).
• Hypoglycemia can also be a side effect of some diabetes medications, including insulin and oral drugs (such as Glipizide and Glyburide) that promote insulin production. Some drug combinations (e.g., Glipizide and Metformin or Glyburide and Metformin) may also cause hypoglycemia. Therefore, it's important to provide your doctor with full information about your medications, vitamins, and supplements (including herbs).

Recognize the symptoms of hypoglycemia. There are various physical and mental signs that can help you identify hypoglycemia, including:

• Trembling
• Dizziness
• Fatigue
• Confusion (e.g., difficulty remembering the date or time)
• Changes in mental state, poor concentration, or drowsiness
• Cold sweats
• Coma (Note: severe disorientation and coma do not occur unless blood sugar drops to 45 mg/dL or lower.)

Prevent hypoglycemia. Check your blood glucose levels at least once a day (upon waking up and before meals). Follow the recommendations above, exercise regularly, and maintain regular meals and snacks throughout the day. Always carry a snack when going out for emergencies.

• Additionally, people with diabetes or those prone to hypoglycemia should inform friends, family, and close colleagues about their symptoms, so they can assist in case of a rapid or severe hypoglycemic episode. For children, teachers should be trained to recognize and treat hypoglycemia in children.
• Consider carrying identification that indicates you have diabetes, such as a medical alert bracelet or a wallet card, so others can assist you in case of an emergency.
• Be cautious when driving, as hypoglycemia symptoms can pose a driving hazard. If going on a long drive, check your blood glucose frequently (especially before setting off) and snack to keep your glucose levels above 70 mg/dL.

Consult your doctor. Notify your doctor if you frequently experience hypoglycemia (more than a few times a week) so they can adjust your medication dosage accordingly.

• Always bring a record of your blood glucose levels to help your doctor determine when insulin levels are too high and glucose levels are too low. This allows them to plan the correct timing for insulin (whether frequent, temporary, or long-acting). Taking your medication at the right time of day (based on your glucose log) can help prevent hypoglycemia.
