Many people live with high blood sugar for years without realizing it because the early symptoms are often mild and vague, according to Verywell Health.
However, if not well controlled, high blood sugar can cause serious damage to the eyes, heart, kidneys, nerves and even the feet.
Barbie Cervoni, a nutritionist working in the US, pointed out the signs of high blood sugar.

Thirst and frequent urination
When blood sugar levels are too high, the kidneys try to filter and excrete the excess through urine. This process draws water from the body's tissues, leading to dehydration. Even after drinking plenty of water, your mouth remains dry and your throat remains thirsty.
At the same time, the patient often has to urinate, especially at night. These are the two earliest and most obvious signs of increased blood sugar.
Hungry and tired
When the body cannot use blood sugar for energy, cells become starved for energy.
The patient will feel unusually hungry, eat more but still feel tired and lethargic, especially after eating a lot of starch.
Blurred vision
High blood sugar causes the body to pull water from the lens in the eye, disrupting the ability to regulate it. This condition causes the patient to feel blurred vision and difficulty concentrating.
susceptible to infection
High blood sugar affects the immune system, making the body susceptible to attack by bacteria, fungi and other pathogens.
The high sugar environment in the body creates favorable conditions for bacteria and fungi to grow. At the same time, slow-healing skin wounds, dry skin, and itching are also easily recognizable symptoms.
Skin discoloration and dark patches
A typical manifestation of insulin resistance is the appearance of dark, thick, velvety patches of skin, often found on the neck, armpits or groin.
Change emotions
High blood sugar can cause mood swings. People may become more irritable or sad, especially after meals.

Stomach-ache
Prolonged hyperglycemia can damage the nervous system that controls the stomach, slowing down digestion. Patients may experience nausea, bloating, and mild epigastric pain.
More serious cases can be ketoacidosis. This is a dangerous complication that requires immediate emergency treatment.
Unexplained weight loss
Children with type 1 diabetes often drink a lot of water, urinate a lot, eat a lot but lose weight quickly.
Numbness in hands and feet
Prolonged high blood sugar will damage the peripheral nerves, especially in the hands and feet. The patient will feel numbness, tingling, pain or loss of sensation. This is a common complication in people whose blood sugar has not been well controlled for a long time.
Chronic hyperglycemia can lead to many dangerous complications such as damage to the eyes (retina), kidneys (kidney failure), nerves (loss of sensation in hands and feet, digestive disorders), cardiovascular disease and stroke.
