10 Keto Flu Symptoms
Symptom #3: Headache
Headaches are among the frequent symptoms experienced during ketosis; the period when the body adjusts to using ketone bodies as a source of fuel. The reason for this is low blood glucose levels, a state referred to as hypoglycemia. This is a common occurrence during this transition period.
With decreased glucose levels, supply of energy to the brain is also diminished, which may interfere with brain function. Remember that the brain is one of the greatest users of the body’s energy reserves. It also receives a large proportion of the total blood supply. The headaches may be worsened by dehydration that usually also occurs during ketosis due to an increased urge to pass urine.
