Signs and Symptoms of Low Blood Sugar Levels

The medical condition of low blood sugar level is also known as hypoglycemia, and it occurs when the level of glucose or sugar in your bloodstream drops below normal.

The acceptable blood sugar level is 70 mg/dL (3.9 mmol/L) and any reading below this, is harmful but occurrence below 54 mg/dL (3.0 mmol/L) requires prompt action. Generally, hypoglycemia can cause short- and long-term complications for the patient. A cursory look at the causes of this condition includes skipping or delaying meals, less than enough carbohydrate foods in one’s meals, largely inadequate food intake, excessive consumption of alcohol, intense physical activity and the over-reliance on certain medically prescribed drugs. People who take insulin for the management of diabetes are at a high risk developing low blood sugar levels.

Spotting the signs and symptoms of low blood sugar is vital, as prompt action can help prevent complications. In this article, we will discuss the common signs and symptoms to watch out for.


  1. The feeling of dizziness

A primary symptom of low blood sugar is the feeling lightheaded or dizzy or as if you're about to faint. This is because your brain is not receiving enough glucose to function properly. If you suddenly experience dizziness or a spinning sensation, it could be an indication of low blood sugar levels. You can treat hypoglycemia quickly with 15g to 20g of fast-acting carbs, such as juices, as suggested by medical experts. Pay attention to this symptom, especially if it happens after a meal or during periods of increased physical activity.


  1. If you experience fatigue or weakness

Low blood sugar can also lead to fatigue and weakness. When your body lacks glucose, which is its main source of energy, you may feel excessively tired or weak. This can impact your daily activities, making it difficult to concentrate or perform physically demanding tasks. If you notice a sudden onset of fatigue or weakness, it is important to consider the possibility of low blood sugar.


  1. Excessive sweating

Sweating is commonly the first sign of hypoglycemia. If you find yourself sweating excessively, even in cool environments, it could be a sign of low blood sugar. Sweating is the body's way of trying to cool down, and when blood sugar levels drop, it can trigger this response. If you experience unexplained sweating, especially when combined with other symptoms like dizziness or weakness, it may be time to check your blood sugar level.


  1. Anxiety and irritability

Low blood sugar can also affect your mood, leading to feelings of anxiety or irritability. When glucose levels drop too low, hormones such as epinephrine and cortisol are released, signaling the liver to release more sugar in the blood, an episode which leads to anxiety. When your brain lacks glucose, it can also trigger emotional changes and make you more prone to mood swings. If you notice yourself feeling unusually anxious or irritable, especially if it is accompanied by other symptoms like lightheadedness or sweating, it is worth considering the possibility of low blood sugar.


  1. Hunger and cravings

Another common sign of low blood sugar is increased hunger or cravings, particularly for sugary foods. When your body senses a drop in glucose levels, it can trigger intense cravings for quick sources of energy. It will result in a strong desire for sweets or carbohydrates. If you find yourself constantly hungry or experiencing intense cravings, it might be worth checking your blood sugar levels to rule out hypoglycemia.

  1. Poor concentration

When blood sugar levels are low, your brain may struggle to concentrate and focus. This can make it challenging to perform tasks that require mental clarity. If you find yourself having difficulty concentrating, experiencing brain fog, or feeling easily distracted, low blood sugar could be a potential cause. It is important to address this symptom to ensure optimal cognitive function.


  1. Blurred vision

In some cases, low blood sugar can cause blurred vision or changes in your eyesight. This happens because the lenses in your eyes rely on glucose to function properly. When blood sugar levels drop, it can affect the way your eyes focus, leading to temporary vision problems. If you experience sudden changes in your vision, it is essential to consider the possibility of low blood sugar.


Some preventive action to consider.


  • Don’t skip meals
  • Check your blood sugar level regularly and know the associated symptoms
  • Always have sugary snacks with you
  • Consume less amount of alcohol
  • Regulate your exercise regime


Finally, recognizing the signs and symptoms of low blood sugar is crucial for prompt intervention and management. It is therefore important to note that if you continue experiencing any of the symptoms, you are advised to check your blood sugar levels using a glucometer or seek medical attention. Remember, early detection and appropriate treatment can help prevent complications and ensure your well-being.
