What is blood sugar level?

Blood glucose or sugar is a sugar present in your blood. This sugar comes from the food you eat. Insulin secreted by the pancreas converts the sugar to energy and makes this energy available to your body’s cells. When your body cannot produce insulin or cannot utilise the insulin, too much sugar remains unconverted in your bloodstream. This raises your blood sugar levels. An increase in the blood sugar levels in your body leads to diabetes. Read on to find out what is a normal level of blood sugar.

What Factors Affect Blood Sugar Level? 

Many factors can cause fluctuations in blood sugar levels: 

  • Food: If you have diabetes, you must watch your carbohydrate intake. You should limit your rice, pasta, cookies, and white bread intake. Eating a balanced diet that consists of carbohydrates, protein, fat, and fibre would be beneficial in managing blood sugar levels. To keep the blood sugar levels consistent, you must go every 3 to 5 hours. Do not skip meals. Three nutritious meals and some healthy snacks can steady your blood sugar levels. Drink water instead of juice or soda. 
  • Physical Activity: Exercise can be highly beneficial in maintaining your blood sugar levels since physical activities burn energy. Regular exercise helps in keeping your blood sugar within the normal range. 
  • Medications: Certain medications can raise your blood sugar levels. 
  1. Common steroids such as hydrocortisone and prednisone used to treat rheumatoid arthritis and allergies can affect your blood glucose levels
  2. Drugs that treat high blood pressure, such as thiazide diuretics and beta-blockers, may affect your blood sugar levels.
  3. Birth control drugs 
  4. Statins used to lower cholesterol 
  5. Isotretinoin for acne 
  • Medical conditions: Hormonal conditions: Your body produces hormones to fight illnesses. These hormones can raise your blood sugar levels. 
  • Age: Blood glucose levels increase with age. 
  • Stress: Stress is another factor contributing to increased blood glucose levels. 
  • Dehydration: Dehydration raises your blood sugar levels, and it would be beneficial to keep yourself hydrated to manage your blood sugar levels.
  • Menstrual periods: Hormonal changes in women during the premenstrual phase can cause high blood sugar levels. If you notice that your blood sugar levels are raised during the week before your period, it would be helpful to reduce your carbohydrate intake during that time.
  • Alcohol: Alcohol consumption in moderation does not pose a problem. However, people consuming alcohol excessively drain their energy storage within a few hours, reducing the effectiveness of insulin. It can lead to very low blood sugar levels.

High Blood Sugar Level

If you have been wondering the maximum level for diabetes patients, read on to find out the symptoms and causes of high blood sugar levels. 

High blood glucose or hyperglycemia occurs due to too much sugar in your bloodstream caused by insufficient insulin. 

High blood sugar levels occur if you have not taken your diabetes medication or insulin. 

Not following your diet and exercise regimen may lead to high glucose levels in your blood. Stress and illnesses also contribute to an increase in your sugar levels.

The symptoms associated with high blood sugar are: 

  • Vomiting
  • Excessive thirst and hunger 
  • Rapid heartbeat 
  • Vision problems 
  • Frequent urination 
  • Weakness 

Targeted  Blood Sugar Level for Teen and Adult

To achieve the targeted blood sugar levels, follow a balanced diet, exercise regularly, and take your medications on time. Study the targeted blood sugar level chart to know a good sugar level for a person with diabetes. 


If you have diabetes, your blood sugar levels fluctuate based on factors such as the food you eat, physical exercise, medications, medical conditions, age, stress, menstrual periods, and alcohol. High blood sugar is caused by insufficient insulin in your body or inadequate insulin production in your body. Skipping medication or insulin, eating carbohydrate-rich meals, getting inadequate physical exercise, and stress cause high blood sugar levels.

Monitor your blood sugar levels regularly. Learn how to check diabetes levels with a blood glucose meter. Monitoring your blood sugar levels gives you a fair idea about whether your diabetes medication has been effective or not. If your medication hasn’t been effective, your doctor may change your medication or suggest a combination of medication.
