High Blood Sugar: If your blood sugar gets high as soon as you wake up in the morning, it seems disturbing. Especially when you haven’t eaten anything the whole night. This condition creates even more confusion in people with type-2 diabetes or prediabetes. But experts say that increasing blood sugar on an empty stomach is a common thing and some natural processes of the body and some lifestyle reasons work behind it. The most common reason for this is Dawn Phenomenon. This is the time when the body releases certain hormones between 2 am and 8 am. Like cortisol, growth hormone, glucagon and adrenalin. These hormones prepare the body for the day’s activity and during this time the liver releases glucose into the blood so that energy remains in the morning.

In people where insulin works well, the body quickly handles the extra glucose. But in people with type-2 diabetes or insulin resistance, this glucose is not balanced, and morning blood sugar appears higher than expected. Gurugram-based physiologist Dr. Nalin Vikas says that this process is normal for the body, but in case of insulin resistance, it can increase blood sugar.

Sugar also increases due to these reasons

In some cases, increased sugar in the morning can also be due to Somoji effect. This happens when blood sugar drops too low at night and the body releases stress hormones to protect it. These hormones increase blood sugar excessively, and the morning reading comes high. Many times people mistake it for the dawn phenomenon, but it is actually a rebound from nocturnal hypoglycemia. Apart from hormonal reasons, many lifestyle factors also increase sugar in the morning. Stress and poor sleep increase cortisol, which further increases insulin resistance. Eating late at night, especially carbs or sweets, keeps glucose high throughout the night. Taking medicines at the wrong time can also spoil the fasting sugar. Apart from this, low activity makes the body weak in using glucose.

How can we control it?

Dr. Vikas advises that morning sugar can be controlled only by understanding all these reasons. He emphasizes that diabetes management does not depend only on medicines, but a balance between diet, sleep, stress and activity is very important. Eating a light and low-carb dinner in the evening prevents glucose spikes at night. Taking a short walk after dinner improves insulin sensitivity. Taking care of sleep and stress maintains hormonal balance. Checking blood sugar occasionally at night helps in identifying whether the problem is Dawn phenomenon or Somogy effect and setting the timing of the most important medicines as per the doctor’s advice.
