Keeping track of your blood sugar levels is very important, as is recognizing the symptoms of high blood sugar levels. They are easy to identify and should be treated ASAP, as they can harm your health if left untreated.


The symptoms may vary depending on numerous factors, but today we’re going to show you the most common symptoms of high blood sugar levels that you need to pay attention to.

Hyperglycemia develops when the body isn’t able to produce enough insulin or can’t use it properly. Insulin is a hormone that makes helps glucose from food to enter the body cells where it’s used as energy.

However, if you’re suffering from insulin deficiency, the glucose is unable to be absorbed into the bloodstream. If this goes on for a prolonged period, some body parts such as the kidneys, blood vessels, nerves and eyes may be permanently damaged.


• Physical inactivity;
• Fatigue;
• The common cold;
• Dehydration;
• Excessive eating;
• Excessive use of steroids.

Increased blood sugar levels don’t automatically mean diabetes, and they may be one symptom of the disease. People suffering from diabetes may not experience many symptoms, but these are the ones that indicate high blood sugar levels:

• Frequent urination, especially overnight;
• Blurred vision;
• Dry mouth;
• Thirst;
• Impotence;
• Difficulty focusing;
• Slow healing of cuts and wounds;
• Recurring infections;
• Digestive problems;
• Increased appetite;
• Nerve problems;
• Dry and itchy skin;
• Excess belly fat and weight gain.


In order to control your blood sugar levels, it’s very important to know what foods you can eat. Foods with a high glycemic index should be avoided. The Glycemic index is a scale which shows the number of carbs in foods which may increase your blood sugar levels. The higher the number, the bigger the risk of high blood sugar levels. The numbers range from 0-100 – foods between 0 and 54 are considered low glycemic foods.

Your diet can affect your health in general, so if you experience any symptoms of hyperglycemia, you need to change your habits before major problems occur.

When we hear people discussing high blood sugar levels, the first thing most of us think of is diabetes. Diabetes is an extremely serious condition but long before someone is diagnosed with it, their body will show signs that their blood sugar levels are too high. By educating ourselves on these signs of high blood sugar, we can avoid causing irreversible damage to our bodies.

The consumption of glucose through our diet is the most likely cause of elevated sugar levels. Glucose is distributed to every cell in the body and is an essential nutrient (in the right sized doses). However, when the levels of glucose become too high for too long, serious damage is caused to your kidneys, blood vessels, nerves, and eyes.

With processed and artificial food making up a significant portion of many people’s diet, the number of people suffering from high blood sugar is increasing. The only way to protect yourself and your loved ones is to begin reading the signs.

Signs of High Blood Sugar

Many of the symptoms on this list are often overlooked as signs that you are feeling ‘a little under the weather’ and that they will pass naturally. The reality is that your body is warning you that there is a chemical imbalance that needs rectifying. So keep an eye out for these symptoms:

• Frequent urination and urination during the night
• Blurred vision
• Difficulty concentrating
• Dry mouth
• Impotence
• Recurrent infections
• Slow healing of cuts and wounds
• Stomach problems
• Constant fatigue or extreme tiredness
• Increased thirst
• Dry and itchy skin
• Constant hunger
• Excess abdominal fat/weight gain
• Nerve problems

If blood sugar is a concern…

There is the Glycemic Index (GI), which indicates the number of carbohydrates in food products, in order to highlight those foods to avoid and which to eat. The GI measures food from 0-100, based on a system of the lower the number, the lower the glucose content.

Three high sugar foods to avoid

If you have either recognized symptoms in yourself or are proactively looking to avoid high blood sugar, certain foods should be removed from your diet immediately. Alongside the obvious advice to avoid processed sweets and fizzy drinks, these three foods should be banned from the house of anyone suffering from high blood sugar.
1. One slice of white bread – GI score 70

Considering that sandwiches require two slices of bread, continuing to eat white bread could be significantly raising your blood sugar levels. Switch it out for brown!
2. Rice cake – GI score 78

Although they can be eaten as a healthy snack if your blood sugar level is low or normal, eating them if you are already suffering from high blood sugar is extremely dangerous.
3. Baked potato – GI score 85

A staple part of many people’s diet, the baked potato will do you no favors if you are monitoring your blood sugar. Avoid at all costs if you are suffering any of the symptoms on the list above.

Three low sugar foods to enjoy

For those of you who are serious about reducing your blood sugar levels and maintaining them at a healthy rate, you should look to manage your diet effectively. That means eating low sugar foods, and the three here are some of the best for the job.
1. Walnuts – GI score 15

Great food for snacks or added to a salad, walnuts are low in sugar and have a range of other health benefits including boosting reproductive health (for men) and heart health.
2. Broccoli – GI score 10

Broccoli might have been many people’s least favorite vegetable as a child, but it actually helps repair the damage caused to your blood vessels by high blood sugar. Healthy and bulky enough to act as a substitute for meat, broccoli is a must in your diet.
3. Eggs – GI score 0

With absolutely no carbohydrates at all, a diabetic could dine on them all day every day if they so pleased (it would probably get pretty boring after a while). When not eaten to excess, eggs are great for your health and certainly won’t elevate your blood sugar.

Keeping tabs on your health is crucial to understanding where the deficiencies or excesses of your diet lie. With so many manufacturers filling their foods with high levels of sugar, it is easy for your body to become overloaded. Don’t assume that consistent issues are natural; it’s probably your body reaching out and trying to tell you something. When it does, don’t ignore it.
