Low blood sugar, or hypoglycemia, most often occurs as a side effect of medication in people with diabetes, but it can also be caused by lifestyle factors or underlying medical conditions.
You're more likely to get low blood sugar if you: take too much insulin. have problems with the way you inject insulin, such as injecting in the same place too often. miss or delay meals, or do not eat enough carbohydrate.
Possible causes, without diabetes
Five key signs your blood sugar (glucose) is too low (hypoglycemia) include feeling shaky/weak, sweaty/pale, dizzy/lightheaded, experiencing a fast or pounding heartbeat, and having trouble concentrating, feeling irritable, or suddenly very hungry, all signaling the body needs quick energy.
Hypoglycemia involves low blood sugar levels. Various other conditions, including anxiety and menopause, can cause similar symptoms, such as headaches, fatigue, and shakiness. Dehydration, salt deficiency, and heat exhaustion can mimic hypoglycemia symptoms.
Hyperglycemia is a common occurrence in critically ill patients, even in those without any history of diabetes mellitus. During stress, injury or trauma, glucose metabolism will be altered because of changes in endocrine secretions and peripheral insulin resistance, resulting in hyperglycemia (1-3).
Stress can cause fluctuations that lead to both high and low blood sugar levels, and each comes with its own set of symptoms. Being aware of these warning signs can help you act before things get worse, whether you have diabetes or are simply feeling the effects of stress on your body.
For example, an older study found that participants with low blood sugar due to type 2 diabetes had an increased risk of developing heart-related conditions and problems in the blood vessels. Hypoglycemia can also increase the risk of other conditions, including: eye disease. kidney disease.
Honey contains the simple sugars glucose and fructose which can raise blood glucose quickly. Keeping small honey packets or honey sticks with you is a dietitian's favorite as they're compact, easy to carry, and work fast. 100% apple juice is mild in flavor when compared to other fruit juices and has very little fiber.
Physical activity, especially intense or new forms of exercise, can cause your blood sugar to decrease. Eating or drinking something with carbs or sugar before you start can help prevent a drop. Also, make sure you drink enough water during exercise, as dehydration can cause blood glucose levels to drop.
Low blood glucose at night
When blood glucose levels fall below 70 mg/dl while sleeping at night, the person experiences a condition called nocturnal hypoglycemia. Studies suggest that almost half of all episodes of low blood glucose — and more than half of all severe episodes — occur at night during sleep.
Therefore, meals that are high in simple carbohydrates can contribute to reactive hypoglycemia. Concentrated sweets such as candy, table sugar, soft drinks, cookies, cakes, and ice cream are mainly simple carbohydrates. Avoid these foods unless they are made with sugar substitutes.
Medicines that can cause drug-induced low blood sugar include:
A blood sugar level below 70 mg/dL (3.9 mmol/L) is low and can harm you. A blood sugar level below 54 mg/dL (3.0 mmol/L) is a cause for immediate action. You are at risk for low blood sugar if you have diabetes and are taking any of the following diabetes medicines: Insulin.
Constantly low blood pressure can be dangerous if it causes signs and symptoms such as:
The causes can include conditions such as liver disease, kidney disease, and hormone deficiencies (lack of certain hormones). It can also happen in people who have had certain types of weight loss surgery. Some medicines, such as certain heart medicines and antibiotics, can also cause it.
Glucose is the body's main source of energy. In most people, blood sugar levels should be within a range of 70 to 99 milligrams per deciliter (mg/dL). Most healthy people only need a quick high-carb snack, such as an apple or banana, to help get their blood sugar back up to normal.
Ways to manage your blood sugar
Hypoglycemia (low blood sugar) is common in people who have diabetes. But it can also sometimes affect people without diabetes. You need to treat hypoglycemia as soon as possible by consuming carbohydrates. If it's left untreated, severe low blood sugar can be life-threatening.
Five key signs your blood sugar (glucose) is too low (hypoglycemia) include feeling shaky/weak, sweaty/pale, dizzy/lightheaded, experiencing a fast or pounding heartbeat, and having trouble concentrating, feeling irritable, or suddenly very hungry, all signaling the body needs quick energy.
If blood glucose drops really low, the person is not able to function because physical and mental changes occur. They can have seizures or become unconscious. Hypoglycemia is the medical term used when the amount of glucose (sugar) in someone's blood is lower than 70 mg/dL, with symptoms and signs noted above.
Try one the following healthful snacks before bed to help manage blood sugar levels and satisfy nighttime hunger:
The fear of blood sugar fluctuations can be very stressful. Changes in blood sugar can cause rapid changes in mood and other mental symptoms such as fatigue, trouble thinking clearly, and anxiety. Having diabetes can cause a condition called diabetes distress which shares some traits of stress, depression and anxiety.
The reason is: Your brain!
If you don't have enough glucose to “feed your brain,” your brain can go haywire. Even though it seems like you are overly emotional, this is actually a physical response to low BG (aka hypoglycemia). You don't have to be below a certain number, like 70 mg/dL, to experience this.
