7 Signs That Your Blood Sugar Levels Are Too High


Blood sugar, or glucose, is the main source of energy for the cells in the body. This type of sugar is found in flours, honey, carrots, and rice, amongst other foods.

This energy helps us perform important bodily functions such as digestion, and the functioning of the heart and synapses, as well as other. The sugar found in our blood must be kept between 70 and 110 mg/dL to make the most of its benefits, without negative health consequences.

A high level of blood sugar is called hyperglycemia and can cause damage to various organs. Then your blood sugar is above 180 mg/dL it’s diagnosed as diabetes mellitus. It’s important to keep this condition under strict medical observation, since it can cause many complications.

What is hyperglycemia?

Hyperglycemia is when your blood sugar level is above 140 mg/dL. This condition can happen for one of two specific reasons:

  • Your pancreas is having problems in creating the right amount of insulin, the hormone responsible for regulating blood sugar levels.
  • The body can’t use insulin properly.

In either case, it’s crucial that you visit a doctor to find out what medications you need, find out about necessary changes to your diet, and the amount of exercise you need to do.

Symptoms of high blood sugar levels

Hyperglycemia is difficult to detect if you don’t pay close enough attention, but there are always symptoms. The best thing to do is to have a medical examination every 6 months in order to get an early diagnosis for any changes occurring with your body.

A blood sugar test is normally very cheap and simple. A small amount of blood will be taken and that’s all. In any case, the symptoms you need to watch out for are:

1. Polydipsia

This is an urgent and exaggerated need to drink water, generally accompanied by the sensation of a dry mouth. It’s important to drink as much water as you need, since it’s the way that the body seeks to regulate blood sugar levels.


However, you must remember that the problem will persist until you normalise your blood sugar levels. To help, include some sporting activity in your day and take medication as indicated by your doctor.

2. Skin lesions

Excessive sugar in your blood can cause the appearance of skin lesions, coffee coloured marks on the legs, reddening of the face, and dry skin. You nails, palms, and soles of your feet can also turn yellow.

If you notices that any bruises appear and seem to last for a lot longer than normal, visit your doctor as soon as you can. Don’t ignore these symptoms, since they could be damaging your blood vessels.

3. Mood swings.

Hyperglycemia can cause many changes in your mood, such as irritability or depression. There are people who have a tendency to get grumpy, or have a more aggressive character, but if it’s not something common for you, this could be a symptom.

Remember that emotions depend of chemical processes in the brain, and these processes are affected by blood sugar levels.

4. Weakness and drowsiness

Due to the fact that your cells aren’t able to efficiently absorb blood sugar, energy levels will deplete. This can result in:

  • Weakness
  • Extreme tiredness
  • Drowsiness
  • Fainting

To address this problem it’s crucial that you eat enough fresh vegetables to get high-quality vitamins and minerals. If the problem is very serious, your doctor could provide you with some supplements.

5. Slow healing of wounds

Hyperglycemia causes a severe change in coagulation. This in turn causes a problem with the speed that wounds heal. This change can also cause the appearance of hematomas or bruising.

If you notice that any wounds are taking a long time to stop bleeding, and they don’t heal as fast as normal, you need to address this. Once you get control of your blood sugar levels, this will cease to be a problem.

6. Vision problems

Small veins and vessels in the retina, the macula, and the optic nerve can show signs of damage as a result of hyperglycemia.  Amongst the problems that this damage can cause are:

  • Blurred vision.
  • Dark spots in your field of vision.
  • Pain around the eyes.
  • Difficulty focusing on close objects in lateral of peripheral vision.

Regular visits to an opthamologist can help to identify these problems and stop your blood sugar levels getting excessive.

7. Sexual problems

Damage to nerves and blood vessels caused by high blood sugar levels can result in changes in sexual functions both in men and women. In men, hyperglycemia can cause:

  • Inability to achieve or maintain a firm enough erection in order to havesexual intercourse.
  • Retrograde ejaculation, a change whereby part, or all, of the semen flows through the bladder in place of through the end of the penis during ejaculation.

In woman, on the other hand, it can cause:

  • Vaginal dryness.
  • Absence of diminished libido.
  • Painful sexual intercourse.

Have you noted these symptoms? If so, don’t hesitate and visit a doctor as soon as possible.
