Hyperglycemia – Causes, Symptoms, Diagnosis, Treatment

By Dr Raghuram Y.S. MD (Ay) & Dr Manasa, B.A.M.S
Hyperglycemia means high levels of sugar in the blood. This occurs in patients suffering from Diabetes Mellitus.

This condition is caused when the body is not producing sufficient insulin, a hormone which is needed to convert excess sugar levels in the blood stream to glycogen and hence helps absorb glucose into the cells. This also happens when there is insulin resistance, a condition wherein insulin is produced but is not utilized by the body cells.

Types of Hyperglycemia

  1. Fasting Hyperglycemia – Here the blood sugar is higher than 130 mg/dL, when the person has not taken any food or drink for at least 8 hours.
  2. Post-prandial / After-meal hyperglycemia – Here the blood sugar level is higher than 180 mg/dL, 2 hours after having food. When you don’t have diabetes mellitus, you don’t see your sugar levels shooting above 140 mg/dL unless you have had a large meal.

Uncontrolled blood sugar levels are threat
Frequent episodes of high blood sugar levels can damage nerves, blood vessels and vital organs.

In type 1 diabetes mellitus, there is a buildup of acids in the blood and this condition is called as ketoacidosis.

In type 2 diabetes mellitus extremely high levels of blood sugar can lead to a condition in which your body doesn’t process sugar. This is a potentially dangerous condition and is called as Hyperosmolar nonketotic syndrome.

This is initially characterized by increased urination. Later the urination frequency and volume may come down. One may have dark urine and severe dehydration.

Other measures to control blood sugar levels
Seek doctors advice before trying any home remedies. He may guide you in a proper way about what you are doing or desire to do.

Check your carbohydrates (carbs) – Reduced carbs reduces blood sugar levels.

Choosing the right carbohydrates – Simple carbohydrates made up of one kind of sugar is found in foods like white bread, pasta and candy. They are quickly broken down into sugar. This causes rapid raise in blood sugar. Complex carbohydrates on the other hand are made up of three or more sugars and are broken after long time into sugars. Therefore the sugars are released gradually. Example – whole grain oats and sweet potatoes.

Increase fiber in your diet – Since the fiber slows down the digestion of carb and absorption of sugar, it promotes more gradual rise in blood sugar levels. It includes inclusion of good quantity of vegetables, fruits, whole grains and legumes.

Implementing portion control
This can be achieved by measuring the portion of consumable foods, using smaller plates, avoiding eating restaurants, road side foods, snacks etc, reading the food labels, maintaining food journals and eating slowly. It is useful to manage weight and blood sugar levels.

Eating foods having low glycemic index – The glycemic index was developed to access the response of blood sugar to the foods that contain carbs. Eating low glycemic index reduces long-term blood sugar levels in diabetics. Below mentioned are some of the foods with low glycemic index –

Lose weight – Maintaining healthy weight lowers the risk of developing diabetes. Even a 7% weight reduction can decrease your risk of developing diabetes by up to 58% (reference). Keep a check on your waistline. When your waist measures 35 inches or more if you are a woman and 40 inches or more if you are a man, you have increased risk of developing diabetes. (reference)

Control your stress levels – During stress cortisol and glucagon are increased which consequentially cause blood sugar levels to shoot up. Exercise, meditation and relaxation methods like yoga reduce stress, blood sugar levels. (ref)

Maintain quality sleep – Maintaining good quality of sleep is necessary for good health and to maintain sugar and insulin levels. Poor sleeping habits affect blood sugar levels, insulin sensitivity, increase appetite and cause weight gain. (research)

Sunlight – Diabetes and insulin resistance are linked to low vitamin D levels. Vitamin D plays a vital role in the production of insulin. If the vitamin D levels are low, the person is prone to develop type 2 diabetes mellitus. Exposure for at least 30 minutes to the sun reduces the risk of vitamin D deficiency. Vitamin D rich foods like orange juice, cheese, cereals, yogurt, soy milk etc should be included in the diet.

Foods rich in magnesium and chromium – Deficiency of chromium is said to predispose one to carb intolerance. Magnesium deficiency has been linked to higher risk of developing diabetes. One study showed 47% lower risk of becoming diabetic in people who take good quantity of magnesium. Green beans, broccoli, high bran cereals, nuts, whole grain products, coffee, meat and egg yolks are rich in chromium. On the other hand, dark leafy greens, beans, bananas, whole grains, avocados, dark chocolate and fish are rich in magnesium.

Apple cider vinegar – It influences body’s response to sugars and also improves insulin sensitivity. It can be added to salad or used by mixing in water.

Does hyperglycemia always cause symptoms?
Hyperglycemia usually causes noticeable symptoms when the blood glucose levels are significantly elevated, above 180-200 mg/dL.

Elevations of symptoms of hyperglycemia are not spontaneous and often take place over several days or even weeks.

If the symptoms are controlled earlier and if the condition is maintained well, the symptoms might not get serious. On the contrary if the blood glucose levels in hyperglycemia remain high for long time, without being addressed, the symptoms may get serious enough and also produce complications.

It is interesting to note that despite elevated sugar levels in the blood, some people suffering from type 2 diabetes mellitus for a long time might not show any symptoms.

b. Emergency complications – if blood sugar levels are high enough for prolonged time period it would lead to serious and life threatening complications. They are –

Diabetic ketoacidosis – happens due to deficit insulin levels in the body. Consequentially the glucose in the blood cannot enter the cells leading to raised blood sugar levels in the blood. Since the cells can’t get energy, there would be break down of fat to derive energy. This produces ketones which are toxic acids. The excessively accumulated ketones in the blood eventually spill over into the urine. This condition is called ketoacidosis. It leads to diabetic coma if left untreated and may become life-threatening.

Hyperglycemic hyperosmolar state – This condition manifests when you produce insulin but the insulin does not work properly. Blood sugar level in the blood becomes very high. The body cannot use either glucose or fat for energy since the insulin is not working. The glucose is spilled into the urine. As a result there is excessive urination. When this condition is not treated diabetic hyperglycemic hyperosmolar state can lead to life threatening dehydration and coma. This condition should be treated as soon as possible.
