HYPOGLYCAEMIA

Hypoglycaemia, also known as low blood sugar, can cause a range of symptoms that can vary in severity. These symptoms typically occur when the blood glucose (blood sugar) level drops below the normal range. Here's a breakdown of symptoms:

• Nervousness: Feeling anxious or nervous is a common symptom of hypoglycaemia. The brain relies on glucose as its primary energy source, and low blood sugar can affect brain function and mood.

• Big Appetite: Sometimes, individuals with hypoglycaemia experience intense hunger (polyphagia) as the body tries to increase blood sugar levels by prompting you to eat.

• Fatigue: Low blood sugar can lead to feelings of extreme tiredness or fatigue. It can make you feel weak and sluggish.

• Shaking: Trembling or shaking is a common symptom of hypoglycaemia. It's often referred to as "the shakes."

• Dizziness: Hypoglycaemia can cause dizziness or light-headedness, which can be particularly noticeable when standing up quickly.

• Carelessness or Lack of Concentration: Cognitive function can be impaired when blood sugar levels drop too low. This can lead to difficulty concentrating, making decisions, or thinking clearly.

• Irritation: Mood swings, irritability, or a feeling of being on edge are common emotional symptoms of hypoglycaemia.

• Rapid Heartbeat: A rapid heart rate (tachycardia) can occur as the body responds to low blood sugar by releasing stress hormones like adrenaline.

• Headache: Some individuals with hypoglycaemia may experience headaches as a symptom.

• Stuttering When Speaking: Speech difficulties or stuttering can occur due to impaired brain function caused by low blood sugar.

• Blurry Vision: Vision changes, including blurred or double vision, can be a symptom of hypoglycaemia.

• Loss of Consciousness: In severe cases of hypoglycaemia, loss of consciousness (fainting) can occur. This is a medical emergency.

• Seizures: Extremely low blood sugar levels can lead to seizures in some individuals.

There are several types of hypoglycaemia, each with different underlying causes. Here are some common types:

• Reactive Hypoglycaemia: Reactive hypoglycaemia occurs after eating a meal, especially one high in carbohydrates. It happens when the body produces an excessive amount of insulin in response to a rapid rise in blood sugar levels, leading to a subsequent rapid drop in blood sugar below normal levels.

• Fasting Hypoglycaemia: Fasting hypoglycaemia occurs when blood sugar levels drop below normal during prolonged periods of fasting or not eating, such as when skipping meals or fasting for medical reasons. It can be a result of certain medical conditions, medications, or hormone deficiencies.

• Postprandial Hypoglycaemia: Postprandial hypoglycaemia is similar to reactive hypoglycaemia but specifically refers to low blood sugar levels occurring after eating a meal.

• Drug-Induced Hypoglycaemia: Some medications, such as insulin or certain diabetes medications (e.g., sulfonylureas), can cause hypoglycaemia as a side effect, particularly if the dose is too high or if the medication is not taken with sufficient food intake.

• Insulinoma: Insulinoma is a rare tumour of the pancreas that secretes excessive amounts of insulin, leading to hypoglycaemia.

• Alcohol-Induced Hypoglycaemia: Consuming alcohol, especially on an empty stomach, can cause a drop in blood sugar levels.

• Non-Diabetic Hypoglycaemia: Non-diabetic hypoglycaemia refers to low blood sugar levels in individuals who do not have diabetes. It can occur due to various medical conditions or hormone imbalances.

• Exercise-Induced Hypoglycaemia: Intense or prolonged physical activity can cause hypoglycaemia, particularly in individuals with diabetes who are taking certain medications.

• Inborn Errors of Metabolism: Certain rare genetic disorders can lead to abnormalities in glucose metabolism, resulting in hypoglycaemia.

• Critical Illness-Induced Hypoglycaemia: People who are critically ill, especially in intensive care settings, can experience hypoglycaemia due to complex metabolic changes.

Common causes of hypoglycaemia may be: 

• Excess Insulin in the System: One of the primary causes of hypoglycaemia is the presence of too much insulin in the bloodstream. Insulin is a hormone produced by the pancreas that helps regulate blood sugar levels. When there is an excess of insulin, it can lead to a rapid decrease in blood sugar levels, causing hypoglycaemia. This can occur in individuals with diabetes who accidentally take too much insulin.

• Eating Disorder: Some eating disorders, such as anorexia nervosa or bulimia, can lead to irregular eating patterns and inadequate calorie intake, which may result in hypoglycaemia.

• Low-Carb Meals: Consuming meals that are very low in carbohydrates can contribute to hypoglycaemia, especially if not balanced with other nutrients. Carbohydrates are a primary source of glucose, which the body uses for energy.

• Prolonged Physical Exercise: Engaging in prolonged or intense physical activity without adequate carbohydrate intake can deplete glycogen stores in the muscles and liver, leading to low blood sugar levels.

• Medical Conditions: Certain medical conditions can disrupt normal glucose regulation and lead to hypoglycaemia. These conditions may include hormone deficiencies, liver disease, kidney disorders, and some rare genetic conditions.

• Alcohol Consumption: Excessive alcohol consumption, especially on an empty stomach, can interfere with the body's ability to maintain stable blood sugar levels. Alcohol can impair the liver's ability to release glucose into the bloodstream and can also mask the symptoms of hypoglycaemia.

Medical treatment for hypoglycaemia typically involves raising low blood sugar levels quickly to relieve symptoms. The choice of treatment depends on the severity of the hypoglycaemia and the individual's ability to take oral glucose. Here are some common medical treatments for hypoglycaemia:

• Oral Glucose: If the person with hypoglycaemia is conscious and able to swallow, consuming fast-acting carbohydrates is the first-line treatment. This can include glucose tablets, gel, or simple sugar sources like fruit juice, regular soda, or candy. These sources provide a rapid increase in blood sugar.

• Glucagon Injection: If the person is unconscious or unable to swallow, a family member, friend, or caregiver can administer an emergency injection of glucagon. Glucagon is a hormone that raises blood sugar levels quickly by causing the liver to release stored glucose. Glucagon emergency kits are available by prescription for individuals with diabetes who are at risk of severe hypoglycaemia.

• Intravenous (IV) Dextrose: In severe cases of hypoglycaemia where the person cannot take anything by mouth, they may need intravenous (IV) dextrose, which is a solution containing glucose administered through a vein. This provides a rapid and controlled increase in blood sugar levels.

• Adjusting Medications: For individuals with diabetes, especially those taking insulin or certain oral medications, preventing hypoglycaemia involves careful management of medication dosages. A healthcare provider may need to adjust insulin or medication regimens to reduce the risk of low blood sugar episodes.

• Monitoring and Education: Regular blood sugar monitoring is essential for individuals at risk of hypoglycaemia. Healthcare providers can offer guidance on managing diabetes or other conditions that predispose individuals to hypoglycaemia. Education on recognising and responding to low blood sugar symptoms is also crucial.

Natural treatment options for managing hypoglycaemia, promoting overall health and stable blood sugar levels:

• Regular Exercise: Physical activity can help improve insulin sensitivity and glucose metabolism. It's essential to have a consistent exercise routine, but individuals should monitor their blood sugar levels before, during, and after exercise to avoid hypoglycaemia.

• Adequate Hydration: Staying well-hydrated is important for overall health. Water can help regulate blood sugar levels indirectly by supporting kidney function.

• High Fibre Diet: A high-fibre diet, primarily composed of complex carbohydrates like whole grains, legumes, and vegetables, can help stabilise blood sugar levels by slowing down the absorption of glucose from food.

• Eating Slowly: Eating slowly and mindfully can aid in better digestion and blood sugar control. It allows for more effective insulin response.

• Good Sleep Habits: Getting enough quality sleep is crucial for overall health and can help regulate hormones that influence blood sugar.

• Frequent Small Meals: Eating smaller, balanced meals throughout the day can help prevent large spikes and drops in blood sugar levels.

• Avoiding Alcohol: Alcohol can cause blood sugar levels to fluctuate, and it's essential for individuals at risk of hypoglycaemia to drink alcohol in moderation or avoid it altogether.

• Stress Management: Chronic stress can affect blood sugar levels. Techniques like meditation, deep breathing, and yoga can help manage stress.

• Nutrient Intake: Magnesium, vitamin D, and chromium are micronutrients that play roles in blood sugar regulation. However, it's essential to consult a healthcare provider before taking any supplements to ensure they are appropriate for your specific needs.
