In the age of stress headaches and muscular tension or screen induced headaches, it’s often difficult to tell the root cause of what’s causing it.
Just like fever, headache is also a common symptom of many underlying health conditions, including diabetes. If you have diabetes, one of the reasons behind your frequent headaches could be fluctuations in your blood sugar levels.
As the blood sugar level goes up and down it may cause headache among the patients due to change in level of hormones such as epinephrine and norepinephrine. So, if you have diabetes, do headaches indicate a spike in blood sugar or a dip? Expert answers.
How high blood sugar can cause headaches
“In people with diabetes, headaches can be associated with high as well as low blood sugar levels. When a diabetic is affected by the condition of high blood sugar levels in the body, called hyperglycaemia, the body tries to eliminate the excess glucose, increasing urine production.
As a result, dehydration and inflammation start occurring in the body of the affected, causing constriction in the brain’s blood vessels. This constriction leads to headaches in people with hyperglycaemia,” says Dr Navneet Agrawal, Chief Health Officer, BeatO.
Early morning headaches associated with low blood sugar
On the other hand, a person afflicted by low blood sugar levels in people with diabetes, causing hypoglycaemia may also experience headaches due to a dearth of glucose reaching the brain.
